Definitions
- the present invention relates to telecommunications systems and methods for providing caller information, and specifically for a technique for providing information regarding the location of the calling party.
- a party receiving a call can have access to the identity of the party initiating the call as well as the directory number of the party initiating the call.
- subscriber features such as CallerlDTM allow the recipient of a call to view the calling directory number and the identity of the subscriber who was assigned the calling directory number on a visual display.
- the called party does not have immediate access as to the caller's location.
- the location can only be determined by reference to the calling party's directory number. For example, the area code and first three digits of a directory number (in North America) identify the switch serving the calling party.
- the present invention is also directed to a router for forwarding the approximate location of a calling party, which includes a routing database, means for determining the approximate location of the calling party from the routing database, and transmitting means for transmitting the approximate location of the calling party to the called party.
- the invention is also directed to a method for providing a called party with the approximate location of a calling party by receiving, at an originating switch, a communication from an originating terminal, determining the approximate location of the calling party, concatenating the location of the calling party with the identity of the calling party, and transmitting the location and identity of the calling party to the called party.
- FIGURE 1 is an illustration of a Global System for Mobile Communication
- GSM Public Land Mobile Network
- FIGURE 2 is an illustration of a Mobile Services Center (MSC) in accordance with the present invention.
- FIGURE 3 illustrates a communication between a calling party and a called party using a signaling network.
- GSM Global System for Mobile Communication
- PLMN Public Land Mobile Network
- cellular network 110 which in turn is composed of a plurality of areas 112, each with a Mobile Services Center (MSC) 114 and an integrated Visitor Location Register (VLR) 116 therein.
- Each Location Area 112 is divided into a number of cells 122.
- Mobile Station (MS) 120 is the physical equipment, e ⁇ , a car phone or other portable phone, used by mobile subscribers to communicate with the cellular network 110, each other, and users outside the subscribed network, both wireline and wireless.
- the MSC 114 is in communication with at least one Base Station Controller (BSC) 123, which, in turn, is in contact with at least one Base Transceiver Station (BTS) 124.
- BSC Base Station Controller
- BTS Base Transceiver Station
- the BTS is the physical equipment, illustrated for simplicity as a radio tower, that provides radio coverage to the geographical part of the cell 122 for which it is responsible. It should be understood that the BSC 123 may be connected to several base transceiver stations 124, and may be implemented as a stand-alone node or integrated with the MSC 114. In either event, the BSC 123 and BTS 124 components, as a whole, are generally referred to as a Base Station System (BSS) the area of which is designated by the reference numeral 125.
- BSS Base Station System
- the traffic handler 205 sends the information pertaining to location to the location database application 206, and sends information pertaining to the directory number to the name database application 207.
- the name database application 207 sends inputs and receives outputs from a
- the CN/ND 202 is a database which cross-references directory numbers of MSs (such as 120, in FIGURE 1) with the name of the subscriber who is assigned that directory number.
- the name database application 207 inputs a directory number to the CN/ND 202, the CN/ND outputs the name of the subscriber, who is assigned the directory number, to the name database application 207.
- the location database application 206 inputs and receives outputs from a Location Database 201.
- the Location Database 201 cross-references the location information in the format it is received in by the MSC 203, with approximate geographical landmarks.
- the location information might contain a number associated with the particular cell (such as 122, in FIGURE 1) in which an MS (such as 120, in FIGURE 1) is located.
- the location information might contain the coordinates (such as latitude and longitude) of the location of an MS (such as 120, in FIGURE 1).
- the cross-referenced approximate geographical landmarks can be, for example, the municipality or district where the particular cell (such as 122, in FIGURE 1), or coordinates are located.
- the approximate geographical landmark and subscriber name are concatenated and then inserted into a Calling Name field of an ISUP packet known by those skilled in the art as an Initial Address Message (IAM).
- IAM Initial Address Message
- the location database application 206 can be modified to input the directory number to the Location Database 201.
- the Location Database 201 can be modified to cross- reference directory numbers with approximate geographical landmarks such as, for example, the address of the subscriber who is assigned the directory number.
- the Location Database 201 can then output the address of the subscriber to the location database application 206 for insertion into the ISUP packet built by the ISUP Interface 204.
- FIGURE 3 a terminating switch 303 receiving an ISUP protocol message originating from an originating switch 301 is illustrated.
- the originating switch 301 and the terminating switch 303 service a number of subscriber terminals including those designated as 300 and 304 respectively.
- Subscriber terminal 300 can be, but is not limited to, a telephone, cellular phone, computer, or FAX machine (not shown).
- STP 302 in FIGURE 3 is shown connected to both the originating switch 301 and the terminating switch 303, it should be understood that the STP 302 may be connected to multiple other switches as well.
