Abstract

This is an application for a patent related to the invention of the System for Identifying Multiple mobile terminals of Users with the same base in the same location (SIMU). The SIMU is designed for mobile telecommunication companies to immediately identify users' mobile terminals with a common pseudo-random noise (PN) from a specific base station and enable them to locate information they are looking for faster and more efficiently than previous systems. With less investment costs for extra equipment or facilities, the Invention will serve the users to contact other users, destinations or information wanted. It may be valuable for any individuals, businesses or organizations, or, for military purposes, police work and other intelligence missions. The SIMU is executed as follows. The mobile terminal user inputs his or her information as well as the information he or she wants. A System for Identifying Multiple mobile terminals of Users in the Same Base (SIMUSB) classifies the information by the field, which in turn are classified into the same base (i.e. input data on personal information are corresponded to the information wanted). The collective information is then sent to the System for Identifying Multiple mobile terminals of Users in the Same Location (SIMUSL) installed at the controller of the mobile telecommunication company. The information is stored in a SIMUSL until base station receives access signal (AS) from users located within a common location. On identifying the signal, SIMUSL informs SIMUSB the numbers of mobile terminals of the concerned users in order to access various information on other users or destinations and whether they are located within his or her immediate range. The Invention includes the technology and equipment to achieve this result, which is how to provide information and connect terminals between users.

Description

TITLE OF THE INVENTION: SYSTEM FOR IDENTYFYING MULTIPLE MOBILE TERMINALS OF USERS WITH THE SAME BASE IN THE SAME LOCATION

TECHNICAL FIELD

The Invention seeks to improve the existing technology with various features of mobile terminals combined. The essence of the Invention is to connect a system of identifying multiple mobile terminals of users with the same base (SIMUSB)'s combining function and a system of identifying multiple mobile terminals of users in the same location (SIMUSL)'s filtering function for a novel result. The SIMUSB's combining function is a technology of producing various combinations by classifying the data about the user as well as the information he or she is looking for. The SIMUSL's filtering function is to filter the set of numbers provided by SIMUSB from the PN+AS signal groups received by the controller at the company.

BACKGROUND ART

All the base stations throughout the country are to be classified by different PNs and their locations are precisely registered. And the user's terminal will be connected to the PN of the closest base station from where the terminal is located. To pinpoint the exact location of a mobile terminal, the closest base station may measure the suspension time of the signal received when it receives access signal (AS) of the concerned terminal From the suspension time (X), it can calculate the distance between the concerned base station and the mobile terminal as follows: the distance = ( X/2)CCDOTS (C is the speed of electric wave). From the distance between other base stations and the MT (distance between the nearest base station and MT + Xprime x C). the location of the concerned MT may be deduced by trigonometry calculation I lowever this method of finding out a location is not only costly but also unnecessary except in special occasions In most cases, the consumers require not so much precise locations but rather, the relation between their location and the conditions in the sin rounding area The Invention therefore is designed to form a network of certain - tei minals and provide information of such conditions, rather than figuring out the exact locations of mobile terminals

When a specific mobile terminal is within the range of a certain base station the conti oiler at the mobile telecommunication identifies the PN from the base station and the ΛS tiansmitted with the switching on of the terminal The controller also identifies to the location of the base station to which the specific terminal belongs However this data is only resources For the Invention to be effective these materials must be effectively combined and reconstructed into an innovative way

DISCLOSURE OF INVENTION l T he Invention refers to a total system that identifies and provides various services tor usei s who can share the same input of personal data and look for data on those within a common location through the SIMU

SIMU works on two pieces of equipment the SIMUSL and SIMUSB SIMUSL installed at the controller of the mobile telecommunication companies identifies ASs

20 li om mobile terminals and PNs from base stations SIMUSL then filters the ASs with the identical PNs those that coincide with the data stored in SIMUSB known as the same base (1 e input data on personal information are corresponded to the information wanted) SIMUSB stores the users' personal data as well as that of those they are looking at in classification by fields It then filters users with the same base to send

2^ then terminal numbers to SIMUSL so that the latter mav alert to them the fact that they are in the same location and then receive the data for use

\ combination of SIMUSL and SIMUSB, the SIMU can perform a vast array of sei vices For example, the System can tell whether there is a police chase in pursuit of a suspect (terminal) in a certain category, or whether the category is broad or narrow ^■> w ithout a satellite surveillance system or other costly facilities For an emergency i cscue SIMU can list information of hospitals, police stations, fire rescue units, or administrative agencies in the area in which the user is located The users can find information on restaurants, theaters, hotels, drugstores, etc in the vicinity of where they happen to be as well as general information of the area and even a map if the area o information has been put in The users can also call a taxi, and conversely, a taxi ch ivei can locate a passenger The military, the company or the police can use SIMU m special operations to organize or disassemble at its convenience a tentative network to exchange secure messages between agents and headquarters

\n advantage of the SIMU is that it eliminates the cost of access to the satellite system HI installing large-capacity computers, filling up the base station with bulkv equipment and installing sensors at individual terminals Installing costly facilities or equipment is neither agreeable to modern consumers nor economical SIMU Network on the othei hand can meet the needs of the consumers at a much-reduced cost and with i nu eased efficiency Conducting the search in the categories of small, medium and o lame SIMU is much more effective than existing methods that works in a single uenerahzed-category on the supposition of a generalized demand

( in l ent technologies in location-search systems include the method of searching tei initials with sensors attached via satellite, and the method of searching exact locations oi tei minals bv trigonometry calculation using a special equipment installed at the base ^ station to measure the distance from the mobile station Both require high cost with inefficient results In comparison, its search is conducted among the users with the same base when they are located in a common area in SIMU Thus, it does not require for mobile telecommunication companies to re-install their facilities gear to suit each mobile terminal, but connects the server with the controller at the companies through SIMUSL

BEST MODE FOR CARRYING OUT THE INVENTION

The Invention has SIMUSL and SIMUSB. SIMUSL is controlled by the channels shown in Fig. 2 When users on the same base are in the same location, their mobile terminals send off their specific ASs. Through the antenna of the nearest base station, lo the controller at a MTC identifies the ASs along with the PN of the base station connected with the AS signals SIMUSL installed at the controller at the mobile telecommunication company is connected with SIMUSB As the SIMUSB is constantly providing the numbers of users' terminals or destinations in the same base to the SIMUSL. the SIMUSL immediately identifies number combinations sharing the same l ^ base in the same location The SIMUSL then sends the number combinations to SIMUSB, which in turn sends the concerned data to the terminal of the user who have sent the specific ASs

Fig 3 shows the components of SIMUSL It is designed to reconcile the identification of the same locations coinciding with the existing mobile telephone signal system It

2o also reconciles the automatic linkage between the users and the server or between users SIMUSL is capable of self-programming and constantly being controlled in connection w ith the SIMUSB The most critical unit of this equipment is the SIMUSL's filtering sensor shown in Fig 5 The SIMUSL sensor consists of the link controlling unit and t he filtering unit, which filters numbers in combination As shown in Fig 5, when users

2 who belong to the same base and exit in the same location sends out AS¹ and AS², the base station links them with its corresponding PN¹, and sends the [... PN '+AS ' , PN'+AS" . . .] to the controller of the mobile telecommunication company. These are then combined with signals from other base stations, producing PN'+AS¹, PN'+AS². .. ; PN²+AS³, PN²+AS⁴... PNⁿ+ AS" ... While the filter of the SMUSL sensor is programmed to identify both the preset AS¹ and AS² displayed with a same PN (i.e. PN¹), it recognizes the PN'+AS² and PN^!+AS² and sends the signal to proceed to the next step.

Following the procedures in Fig. 9, SIMUSB performs what has been defined by the combination. Users are supposed to input information classified as his/her own data and others' wanted. The data the user has put in is then distributed among the fields categorized as the user's data or that of others' in the Revelation Unit The Revelation Unit then reveals the association between the data to suit the required function. Then Combination Defining Unit forms combination groups according to the association set by the Revelation Unit. As seen in Fig. 8, each user has the option of forming various combinations with other users, but the relation is shown either by a or b of Fig 8. Those combinations in Fig. 8 are put into the SIMUSL by the Combination Defining Unit as [AB, AC, BC, CE]. If we suppose that As AS value is AS¹, B's AS², C's AS\ D^'s AS⁴, and E's AS⁵, the SIMUSL filter must have an input of [PN+(AS'~ AS²), PN+(AS '~ AS¹), PN+(AS²~ AS³), PN+(AS ^« AS⁵ )]. If the users^' locations are as shown in Fig. 5, the {PN+(AS - AS )} combination has the common location (PN ), so the users will have achieved their objectives.

The "user" here is not confined to mobile terminal users. It could be data regarding destination, or about the locations that the service provider has put in for users The users have the choice to access from the services inputting their own data for further services Also they may define the categories of the location as Small, Medium, and Large, according to which they may get different services In the Small category, the services may include random people search (under applicable law), emergency aid search, destination search, and data retrieval within the location, the same-objective oldei search, and small-scale network formation On top of these, the Medium and 1 aige category services include searches for missing people or friends

1 he procedures of processing field and personal messages of SIMUSB data are shown in P ig 7 The Input/Output Controlling Unit controls the information the user has put in and is looking for The Data Field Processing Unit classifies it, and the Storing Unit stoies it The Combination Producing Unit filters the stored data for combinations of lo numbers of mobile terminals before sending it to the SIMUSL Since the SIMUSL l eceix es filtered data on number combinations, the SIMU can execute the operation at a \ eι v competitive speed Recognizing that the information is readv for the user, the SI MUSB sends the information to the Combination Processing Unit, which in turn sends the data through the Data Processing Unit to the Data Dispatch Unit The data is l _^ t en ehveied through the SIMUSL to the users

I in 1 shows the general structure of SIMU The service provider's server (SIMUSB) c onsists of the Controlling Unit, Launching Unit, Receiving Unit, Sending Unit, Relaying Unit and Data Input Unit, while the Controlling Unit of the mobile telecommunication company is equipped with SIMUSL provided by the service o pi vidci

The execution of the SIMU is shown in Fig 4 When the SIMUSL is installed t hi ough the Input Unit in the Controlling Unit at the mobile telecommunication i ompam oi when the pre-programmed execution file is installed, it sets the same- location searcher into operation When the user enters his/her data as well as the data he/she wants in his/her terminal, SIMUSB classifies, stores, and forms groups of those with the same ranges (bases) It then sends the combinations of terminal numbers of to t he SIMUSL, which stores the combinations in its filters for the user to access When the user is in the common (same) location as his/her destination or as the person he/she i s looking ior, SIMUSL immediately recognize the fact and informs the SIMUSB The ^ S I MUSB then instructs the SIMUSL to connect it to the users SIMUSB then asks, Do von want to see the information you want?" If the user presses Yes (Number 1 ) he/she is led to follow the directions for the information either by pressing certain letters oi bv voice command If the user presses No (Number 2), the SIMU Network is i din ned to its original waiting status When all the intoi mation has been transmitted l o S I MUSB asks the user if it should connect him/her to other users or to the destination he/she wants If the user presses Yes, he or she is connected through the telephone w ith the other user through the SIMU Unless the user requests, his/her terminal numbei s will not be released I he f unctions of the programs in SIMUSL include identifying whether the pre-set

I - i ci minals of users (destinations or information) are in the same location informing S I MUSB of the information it has identified, relaying the data between the user s tci minal and SIMUSB, and, relaying phone connections between users thi ough the SI M USB The first is the most important function of all Fig 6 shows how the S I M U pi ocesses the signals or messages sent to users Ml messages oi data ai e o (. ontiollcd by the Input/Output Controlling Unit and relayed through the Message I l ansmission Unit to the Linkage Controlling Unit As the messages are being relayed to the Linkage Controlling Unit, they are combined with the stored data and l eleased t hi ough the Data Call Processing and Producing Unit They will then be transformed i nto lettei s or voice by choice Then the signals and messages go through the Linkage

2 ⁽ onti olling Unit and Error Controlling Unit, before being sent off to the Controlling Unit of the mobile telecommunication company by either wire or wireless means Tig 10A and 10B shows how SIMUSL works in the system of the company SIMUSL is directly related to location registers including home location register (HLR) and visitor location register (VLR) The HRL is the database needed for a mobile station s (MS) to search for a mobile serviced switching center (MSC) in which it is located as well as of subscription information on the MS The VLR is the database temporarily storing the information on the MS in the coverage area of the MSC (Fig 10A) SIMUSL is interfaced with HLP and VLR An important function of SIMUSL is filtering the terminal numbers of users sharing the same base to check whether they are 0 in the same location In a more advanced system, this filtering function can be controlled by an operation and maintenance center (OMC), a headquarter of the mobile telecommunication company, or a server provided by the company Also, it can be controlled by connecting SIMUSL directly to MSCs In the present cellular mobile telecommunication system, as MS changes a cell area, it ^ is open to send a signal {through the base transmission station (BTS) and base station controller (BSC) to MSC} In the process of performing this job encumbrance can be produced Due to this problem, the mobile telecommunication company sometimes gioups several cells into a specific category and makes the information be sent as a MS is out of the category In this case, the cell unit does not identify the location of MS o However it will be identifiable by changing operating data

The categories of locations (Small, Medium and Large) are determined by cell groups designated by the company being contracted with the SIMU In each category, information stored in LR identifies users on the same base In SIMU a user's location is identified by location registration (Fig 10A) Location ^ l egistration is a process of storing a location information of MS into VLR and HLR, and it is for a mobile telecommunication system to search for MS within a system area Here, the location area is a field in which MS can be roaming without renewing its location information As the MS moves into another location area, location registration restarts There arc three kinds of location registration MSC and VLR carry out the renewal In -> t his case it is unnecessary to provide a new routing information to HLR since location areas are covered by an identical MSC Also, MSC, HLR and VLR are involved in the l enewal of location registration Moreover, the renewal occurs between VLR and HLR as VLR reallocates mobile station roaming number (MSRN)

I n SIMU, location area is renewed by the three cases described above In ordei to show l o t he renewal of location registration in the SIMU, a few but the most significant examples ai e given in Fig 10A-C Fig 10A shows processing procedures of a renewal of location information including MSC, VLR and HLR

I MS moves into an area of a base station covered by a new MSC I s 1 MS i ecognizes that it enters into a new location area through the broadcasting control channel (BBCC) at the base station

MS requests the renewal of its location area using international mobile station identity (IMS1) or temporary mobile station identity (TMSI) I Base station sends a renewal request to MSC 20 ^~ MSC i equests the location area renewal for MS to VLR in the new area ( VLR-new) '-> When there are no information on the MS in the VLR-new and a need to send a new i outing information on MS to the HLR, the VLR-new requests the location area i enewal to HLR

I ILR-new requests the VLR in which the MS has been registered previously (VLR- 2s old) to cancel the information on the MS M The VLR-old informs the HLR the fact that the location cancellation request from the HLR is successfully executed ' i HLR informs the VLR-new the successful completion of its request for the renewal of location area as well as the user's information needed ι The VLR-new informs the MSC the successful execution of the renewal 11 The MSC transmits the messages received from the VLR-new to the base station '-' The base station informs the messages to the MS

I he above procedures of location registration applies to both the PCS and DCN As shown in Fig 10A, SIMUSL and SIMUSB are connected to OMC linked with HLRs I hus, through OMC, SIMUSL can identify the SIMU user's location Fig 10B show the procedures of controlling the user's access signal (AS) as a public switch telephone network (PSTN)/ integrated services digital network (ISDN) user calls a mobile telephone users in the SIMU

I s

I With a t equest of call connection to a mobile telephone user, the PSTN controller carries out preset routing to the nearest gateway digital MSC (GMSC) The GMSC requests the information on the mobile telephone user^'s present location to the HLR in which his/her information concerned is stored _o T he HLR informs the mobile station roaming number (MSRN) including the location information to the GMSC

! Using MSRN, the GMSC is rerouting a call to the MSC covering the area in which the MS is located

^"i The MSC requests the VLR for the information on the mobile telephone user _s '-> VLR sends the information to the MSC According to the user's information provided by VLR, the MSC requests a paging to base stations covering the corresponding location area Base stations carry out a paging

' i The MS senses the call and responds to a base station when the call is for it s ι The corresponding base station informs the MSC the fact that there is a response from the MS and the MSC authenticates the user and encodes his/her information

Fig I OC shows the procedures of the SIMU service provision to the users from different mobile telecommunication systems The users, in and //, request services for l o the identification and connection of each other when they are in a common location (B /^•,^') defined by different telecommunication companies (x anά y)

1 The MSs of the users, m and n, move into a common area (B -E) defined by x and y companies 1 s _ Each MS senses that it has entered into a new location area by broadcasting control channel (BCCC)

Each MS request its location area renewal using international mobile station identity (1MSI) or temporary mobile station identity (TMS1) 1 The corresponding base station sends the location area renewal request to MSC 2o ^"» Each MSC requests the location area renewal to VLR fi Each VLR requests the renewal to HLR when no information on Ms is available in VLR. and there is a need to inform a new routing information to HLR storing the related information of MS ^~ The request from VLR is sent to HLR through MSC and GMSC 2s s Through GMSC and MSC, HLR sends a request of cancellation for the information on MS to the VLR in which MS has been registered before (VLR-old). At this time, the VLR-old informs the VLR-new as the request for location cancellation by HLR is successfully completed. HLR informs the VLR-new that its renewal request for location area has been successfully completed. 5 ^{( |} Through HLRs, SIMUSLs installed at both companies request locations of the users, m and /?, belong to the same base. 1 - Each HLR inform the user' location to the corresponding SIMUSL. ii Since the users, m and n, are located in areas B and E, respectively (B and K are considered as the same location by the SIMU), the SIMUSLs inform the SMUSB lo that m and n are in the same location.

12 SMUSB sends the message prepared to m and n and communicates with them regarding the information they want and whether they want to be connected with each other. 1 5 When m and n sends the signal indicating that they want to be connected with each i s other to SIMUSLs through the SIMUSB, each SIMUSL requests the corresponding

GMSC for the connection between m and n. 1 1 The GMSCs in both mobile telecommunication companies connect in and //

For the provision of the SIMU services shown in Figure 10C, the existing mobile 20 telecommunication system needs to be adjusted for the identification of a minimum unit location At present, messages including changes of cell information are sent off to MSC However, these messages should also be sent off to VLR and HLR A minimum unit of information stored in VLR and HLR is per LAI which is a unit of a base station controller Information is sent directly to MSC, but the information from MSC to 25 VLR and HRL includes the changes occurred in higher than BSC units. Therefore, for the identification of location information in detail at SIMUSL, messages and their pi cessing procedures need to be modified so that the messages sent from MSC to VLR and HLR enable to include the concerned information on cell Also by a connection of SIMUSL to MSC, SIMUSL can receive the information on the changes of cell location s dii ectly from MSC

I n SIMUSL, there are no technical problems in the identification of user's location by a use of terminals available now The fact that ASs sent by MSs are not continuously generated will not limit the provision of the SIMU services to users AS is generated c ontinuously by switching on-off of terminals and reassigning of call channels Changes lo of parameters, location area (with fixed time difference following a timer criterion), and AC signals (exceeding critical distances) generate AS AS is produced when a base station i eceives call/response messages or it requires MS to be re-registered Thus, the mobile telecommunication system can always recognize the locations of MSs For this i cason, SIMUSL can be constantly operated, although the function of MS needs to be l s upgraded to enhance the quality of the SIMU services

I t is desirable for all telecommunication companies to set up identical categories ( l anges) for the same locations For this purpose, the companies need to share a part of their system (1 e base station and MSC) as well as information and technology as necessai y This kind of cooperation, however, will not be accomplished immediately It,

20 howevei will be feasible in near future by the effort for maximizing standardization and i nterchangeability in mobile telecommunication systems Meanwhile, the categories of specific locations in the SIMU can be defined by drawing common categories from cell bundles sd by each telecommunication company Each company can have an access to the infoi mation on the categories of locations by storing it in the SIMUSL oi making

2s 1 II Rs of different companies interchangeable I n the SIMU, upgrading terminals needs to be done in two ways In order for users to be connected to the services in Fig 11, menus indicating services available should be i cvealed in their terminals To accomplish this task, the capacity and function of l ei minals needs to be enhanced ^s I he υsei s of not only mobile terminals but also cable terminals connected to PSTN can have access to the SIMU services (Fig 11 A) Fig 1 I B is a supplement for the Fig I I \ The users are connected to the SIMUSB through the companies they belong to I he services of the SIMUSB include as follows 1 ) information on the SIMU users and \ aι ιous facilities and the connection within and between them. 2) chatting and l o advei tisement, phone home page, personal secretary, games etc , 3) searches for people, ti ansportation. and emergent medical needs (e g blood), 4) connection to various internet sites and 5) network establishment and cancellation Among the SIMU services, i hose w ith the letter B in Fig I I A can be provided by a use of the existing mobile i ci minals In order to have other services in Fig I I A more completely , it is necessary

I s ui upgrade the existing terminals

I he following describes the procedures of providing a service for network establishment at the SIMU

¹ Mobile telecommunication or PSTN users request a netwoi k service to the SIMU 2o _. SIMUSB classifies the users as a network group and pi ovides their phone numbers to SI MUSL

SIM USL identifies the users' locations (I e Small. Medium and Large categoπes) and then sends the concerned information to SIMUSB

i S I M USB connects the users with each other when they are located in the area ^{"• s} where the service requested can be provided Other procedures for a network establishment are similar to those for other services in the SIMU

One can receive the SIMU services by mobile and fixed terminals, as well as by attaching a transmitter to cars or facilities

Without modifying the existing MSC, SIMUSL can be connected to MSC by trunk interface module, used for the connection of MSC to other systems at present λt SIMU users can receive information by the signal path or traffic path methods By the signal path method, information can be sent any time, yet the software in MSC,

10 conti oiler base station and terminals need to be reformed The softwaie do not need to lie l elbi med with the use of traffic path method although the information can be sent off m the idle state of terminals In this case, only the software in terminals and the SIMU need to be upgraded In general, the signal path method is used for short messages while the tiaffic path method is for interactive long messages Thus, it seems economical to

| s use the traffic path method rather than changing the existing hardware at the mobile I elecommunication company

\dditional hardware is necessary for the connection between two terminals In order tor MSC to provide this service, MSC should have a call nuxei equipment bridging two usei s Since this equipment is in the MSC in general, the users can be connected by call 0 nuxei hardware equipment used for a conference call system Additional software will lie definitely necessary So far, there is no software for operator to connect two users w ith each other If the hardware equipment for the connection of usci s is installed in SIMUS1 no modification is necessary in the MSC, yet considerable additional work on softwai e and hardware in SIMUSL needs to be done

2s SIMUSL does not always have to relay a connection between two users It is, thus, possible to provide the concerned telephone numbers to each user after terminating the connection between the users and the SIMUSB. Moreover, it is feasible for the SIMUSB to relay the users be connected to it through all mobile telecommunication companies 5 The SIMU can be operated in various modes such as frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), and packet access. As shown in Fig. 12 and 13, the SIMU can be operated in all personal communication networks (PCN) used world widely such as DCS- 1800, PHS, DECT, GSM, JDC, etc. Figures 14, 15 and 16 show that the SIMU can also be lo operated in the satellite communication system when S-HLR and S-VLR for the identification of location are interfaced with SIMUSL. In this case, even better services can be provided

With the operation of the public land mobile telecommunication system (FPLMTS) and IMT 2000 in the near future, the SIMU will provide services more easily and

I s completely The quality of most of the SIMU services in Fig 1 1 will be improved The SIMU will also have a considerable influence on the establishment of improved intelligence network, the purpose of the future communication system Fig 12 shows how SIMUSL and SIMUSB work in the PHS system and Fig 13 reveals the locations of SIMUSL and SIMUSB in the packet radio PCS network Fig 14, 1 5,

2o and 16 provide the procedures of call transmission at the SIMU in the satellite mobile telecommunication system without and with link between satellites In any of these three cases, the SIMU provides services by connecting SIMUSL to HLR and VLR or MSC following the procedures in Fig 10C in general A SIMUSB will not be able to cover all of the world or a country due to the limitation

2 ^ {^~ computer capacity Thus it is important for a SIMUSB to cover users from an appropriate area and then to link all SIMUSBs in a row so that all service users and locations are connected

I NDUSTRIAL APPLICATION s \s noted above, the Invention offers a lot of benefits Since it does not conduct searches of all PNs and all ASs to locate a certain mobile terminal, the Invention eli minates the need to equip each and all of the terminals with a sensor, build a satellite chasing system, and install a large-capacity computer in the mobile telecommunication companv All it requires is to link the SIMUSB with the Controlling Unit of the l o company and to install the SIMUSL at the controller Such a small investment can achieve full results, thanks to the fact that the SIMU already is equipped with combinations of terminal numbers of users on the same base for their purposes To i ecognize a common (same) location, it does not have to conduct a time-consuming l andom search but merely check whether the ASs from the users sharing the same base i have the same PN Since it is programmed to automatically recognize a PN with the same base AS group, the search is simple The benefit of the invention is not only ec nomic but it can also achieve the various advantageous objectives as noted above With this invention, mobile telecommunication is able to provide various high quality seivices appeared in Fig 1 1 to many consumers With being interfaced with 1MT 2000, o t he SIMU services will be more improved

\s shown in Fig 14, 15, and 16, with the connection among all of the mobile and fixed net win k telecommunications in the world and the installment of the SIMUSBs the ai eas needed web condition like Internet can be established Therefore all users of tei minals for telecommunication enable to connect with each othei as well as with the

2s places and information in the world Mobile terminal is a computer with low capacity This small computer is made to maintain the status of being connected to a web environment by continuously sending ΛS unless switching off of the terminal The SIMU, which identifies users with the same base in the same location, then provides the information needed and connects them with each other, is a new PC or telephone network being able to connect all users and information needed whenever and wherever This telephone network may be behind i n terms of the speed and capacity for transmission than the PC network, however, it is much better than the latter in terms of convenience, immediacy, universality and market shai e T he SIMU will provide a basis of the technology for information and c ommunication necessary to establish web environment in a new dimension
