Abstract

A communication terminal initiates a Wireless Session Protocol (WSP) session by forwarding a request of data to a server. The request comprises an identification of the requested data and a communication terminal identification number provided by the server. The server, when receiving a request containing a communication terminal identification number, recalls user profile information from an associated database memory corresponding to said communication terminal identification number. The user profile information indicates a data format which will be handled by the communication terminal. Then the server replies to the request by forwarding the requested data in the format defined by the user profile information.

Description

1 A method of and a network for handling Wireless Session Protocol (WSP) sessions.
The invention relates to a new method and system for a session service in a wireless session protocoi (WSP) between a user and a server terminal.

The Wireless Application Protocol (WAP) is a result of continuous work to define an industry wide standard for developing applications over wireless communication networks. WAP is disclosed in the Wireless Application Protocol Architecture Specification; Version 30 April 1998; by Wireless Application Protocol Architecture Working Group;

The scope for the WAP working groups is to define a set of standards to be used by service applications. The wireless market is growing very quickly, and reaching new customers and services. To enable operators and manufacturers to meet the challenges in advanced services, differentiation and fast/flexible service creation WAP defines a set of protocols in transport, session and application layers.

The Session layer protocol family in the WAP architecture is called the Wireless Session Protocol, WSP. WSP provides the upper-level application layer of WAP with an interface for session services and management. One example of a session service is a connection-mode service that operates above a transaction (ayer protocol called Wireless Transport Layer (WTP), see also Wireless Application Protocol: Wireless Transport Protocol specification, version 30 April 1998, by Wireless App(ication Protocol Transport Working Group, CONRRMATZON COPY
2 Another session service may be a connectionless service that operates above a secure or non-secure datagram service.

The Wireless Session Protocols comprises one protocol most suited for browsing applications (WSP/B). WSP/B provides HTTP 1.1 fuinctionality and incorporates new features such as long-lived sessions, a common facility for data push, capability negotiation, and session suspend/resume. HTTP 1.1 is disclosed in Fielding, R., et. al., "Hypertext Transfer Protocol-HTTP/1.1 ", RFC 2068, UC
Irvine, January 1997. The protocols in the WSP family are optimised for low bandwidth bearer networks with relatively long latency.

The WAP Architecture is very similar to the Internet Architecture. Fig.1 shows a comparison between the Internet Architecture 10 and the WAP Architecture 20.
The Internet Architecture 10 comprises a Hypertext Markup Language (HTML) 12, e.g.
Java ScriptTM, a Hypertext Transfer Protocol (HTTP) 14, Transport Layered Security (TLS) I Secure Sockets Layer (SSL) 16, and a Transport Configuration Protocol (TCP) / User Datagram Protocol (UDP) 18. The Internet Architecture 10 is a well known prior art, and is disclosed e.g. in US-A-5,657,390. The WAP
Architecture 20 comprises a Wireless Application Protocol (WAE) 22 corresponding to HTML 12 a Wireless Session Layer (WSP) 24 corresponding to HTTP 14, a Wireless Transport Layered Security (VIITLS) 26 corresponding to TLS I SSL 16, and a Wireless Transport Layer (WTP) 28 corresponding to TCP / UDP 18.
Further, the WAP Architecture comprises different bearers 29 like e.g. SMS, USSD and CDMA 30. There is also a possibility to implement different kinds of services and applications in the WAP Architecture, e.g. Value Added Services (VAS). The WAP
Architecture 20 is a well known prior art and more information about the different blocks WAE, WSP, WTLS, WTP and bearers is found in information available from Open Mobile Alliance Ltd.
3 - -The present invention relates to WSP, which provides a means for organized exchange of content between co-operating client/server applications.
Specifically, it provides the applications with a means to:
a) establish an optionally secure, reliable session from client to server, and release the session in an orderly manner;
b) exchange content between client and server;
c) suspend and resume the session.

In addition, WSP also supports a non-confirmed session service. The connectionless session service can be used over unreliable transport when applications do not care about confirmation. The non-confirmed service is accessed outside the context of an established session.

In e.g. the GSM system it is relatively expensive to transfer data. At the same time it is desired to reduce the size of the required memory space in the phone.

EP-A2-0,851,696 discloses a way of providing data from an information database in response to a request from a mobile station in a wireless network, by using short messaging service, SMS. The subscriber uses a mobile station to place a call via the wireless network and a PSTN to an information service provider. An identification (lD) of the mobile station is forwarded to the information service provider. That provider can then use the ID to retrieve a user personal identification number (PIN) or user identification number. The database information service provider constructs a message containing the desired data and the appropriate PIN or user ID number and forwards that to a message centre. The message centre then forwards the data from the provider to the mobile station as an SMS.
4 - ' However, this document EP-A2-0,851,696 uses the ID every time it retrieves a user PIN or user ID number. Thus, this procedure has to be repeated every time when the user sends a request to the server. This means that it will not be easier or faster when the user would like to establish another session.
This is a major drawback since the cost for a call will then increase. Also, this document does not describe how it is possible to support different types of data formats/types, upon sending/receiving a request. One example of a data forrnat/type supported by WAP is the MIME multipart format, which transports composite data objects (e.g. multipart/mixed), see WAP WSP draft version 02-Apr-1998, 7.4 Multipart data. WSP defines a compact binary form of the MIME multipart entity and the content type. Thus, there is a need to support different data formats of a WSP session, and to increase the speed to establish a session.

WO/A2/98/34414 discloses a communication system providing a subscriber unit (e.g. a portable phone) with access to an information network through gateway equipment that is coupled to a network server. The network server conveys data to the subscriber unit, as a respond to a request sent by the subscriber unit, via an SMS message. The request includes an identifier, which is used to communicate with the originating communication device via a message service (SMS) that provides extemal access to the radio communication system. The information network may be a public access network, such as the Internet, comprising world wide web (www) information sites.
However, as in EP-A2-0,851,696, the system in WO/A2/98/34414 has to repeat its procedure every time the user sends a request to the server. Thus, it will neither be easier or faster when the user would like to establish another session, i.e. it will establish the session as it usually does. In other words, the network has to identify the user every time the user would like to obtain data.

EP-A2-0,833,313 discloses a method and a system for transferring data from an Internet Protocol (IP) network to a mobile station in a non-IP network. A
special server acts as an interface between the Internet and a CDPD network. The mobile station could be a mobile phone, and the server is a software platform. The system permits the
5 user to communicate with a data network while either in an idle mode or while in a voice mode.

An object of an aspect of the invention is to provide a method of handling Wireless Session Protocol (WSP) sessions in such a way that the amount of redundant information is reduced.

This is obtained by a method of handling Wireless Session Protocol sessions between a wireless communication terminal and a corresponding server, comprising: the communication terminal initiating a first session by forwarding a request comprising a header indicating a data format which will be handled by the communication terminal;
the server, when receiving a request containing a header, deriving user profile information from this header and storing the user profile information in a database memory and generating an associated communication terminal identification number;
the server forwarding the communication terminal identification number to the communication terminal; the communication terminal initiating a subsequent session by forwarding a second request of data to the server, the second request comprising an identification of the requested data and the communication terminal identification number provided by the server; the server, when receiving a request containing a communication terminal identification number, recalling the user profile information corresponding to the communication terminal identification number from the database memory; and the server replying to the second request by forwarding the requested data in the data format defined by the user profile information. Hereby the server unit is able to store the user profile information for a period and to recall this information when appropriate. The requesting communication unit does not have to transmit information about its user profile once these are stored in the database memory of the server. This information would otherwise have to be transferred in every session, and this would lead to an unacceptable overhead with up to 50 percent of data transferred in the request being redundant user
6 profile information. Once the server has stored the user profile information it provides the communication terminal with a communication terminal identification number that uniquely identifies the communication terminal.

According to the preferred embodiment of the invention the server only stores the user profile information for a predetermined period of time, e.g. 3 hours or 3 days. The period of time may be differentiated in dependence of the kind of subscription the user has. The server deletes the user profile information from the database memory upon expiration of said period of time. In order to avoid double use of the same communication terminal identification number the server informs the communication terminal about the duration of this period, whereby the terminal knows when the period has expired. When the period has expired and the communication terminal starts a new session it has to transfer the user profile once more. When the server has stored the user profile information once more it provides the communication terminal with a new communication terminal identification number that uniquely identifies the communication terminal for a new period.

The invention furthermore relates to a method of handling Wireless Session Protocol sessions between a wireless communication terminal and a corresponding server, comprising: the communication terminal initiating a first session by forwarding a first request of data to the server, the first request comprising an identification of the requested data and a header indicating the data format which will be handled by the communication terminal; the server, upon reception of a request comprising a header, generating a communication terminal identification number and storing the header associated with the communication terminal identification number; the server replying to the first request by forwarding the requested data and the communication terminal identification number to the requesting communication terminal; the communication terminal storing the communication terminal identification number in a memory;
the communication terminal, when subsequently initiating a second session, forwarding a second request to the server, the second request including identification of the requested data and the communication terminal identification number received from the server; and the server upon receipt of the second request recalling the header from the database memory which corresponds to the communication terminal identification
7 number.

The invention furthermore relates to a wireless communication network for handling Wireless Session Protocol sessions between a wireless communication terminal and a corresponding server connected via the network, the server comprising processing means and transmission means, and a database memory connected to the server, the communication terminal comprising means for including a header in a request indicating a data format which will be handled by the communication terminal;
the processing means in the server arranged to derive user profile information from the header, to store the user profile information in the database memory, the user profile information indicating the data format which may be handled by the communication terminal, to generate an associated communication terminal identification number; and to forward the communication terminal identification number via the transmission means to the communication terminal; means in the communication terminal for initiating a subsequent session by forwarding a second request of data to the server, the request comprising an identification of the requested data and the communication terminal identification number; the processing means being arranged in response to receiving the second request to recall the stored user profile information corresponding to the communication terminal identification number and for replying to the request by forwarding the requested data in the format defined by the user profile information via the transmission means to the communication terminal. Such a network will be especially useful when it is used as a cellular network, e.g. a GSM network and the bearer for the request is the standard data transfer or a chain of SMS
messages. The savings in cost for a sessions will be important for the user since the saving of the re-transmission of resending the user profile information several times may reduce the number of transmitted messages by up to 50 %.

When the communication unit is aware that the user profile information is not stored in the database memory of the server, it has to include a header in the request indicating the data format which will be handled by the communication terminal. The processing means in the server is arranged to derive the user profile information from the header, to store the user profile information in said
8 database memory, to generate an associated communication terminal identification number; and to forward the communication terminal identification number via said transmission means to the communication terminal. This communication terminal identification number will be valid for the next session if that occurs within the period set by the server.

According to the invention a server unit for use in a wireless communication network for supporting Wireless Session Protocol sessions, comprising: input means; output means; processing means controlling the input and output means and a database memory; the database memory contains user profile information for a plurality of communication terminals, the user profile information indicates the data format which may be handled by the communication terminal; wherein on receiving a first request, initiating a first session, the first request including a header indicating the data format which may be handled by the communication terminal, the processing means derives the user profile information from the header, stores the user profile information in the database memory, and generates an associated communication terminal identification number; and the processing means forwards the communication terminal identification number via the output means to the communication terminal, and the input means are adapted to receive a second request for data from a communication terminal, the second request initiates a second session and comprises an identification of the requested data and the communication terminal identification number; the processing means recalls the stored user profile information by means of the communication terminal identification number received in the request; and the processing means replies to the second request by forwarding the requested data in the format defined by the user profile information via the output means. Very often it will be the network operator to which a phone user subscribes that operates the WSP server, too.
In practice it can occur that it is the network server that generates the communication terminal identification number to the WSP server, but as far as both the network server and the WSP server are controlled by the same operator these servers may be regarded as are entity. This is also the case when the WSP server operator decides to use communication terminal identification numbers otherwise existing in the system.
9 When the communication terminal includes a header in the request indicating the data format which may be handled, the processing means of the server has to derive the user profile information from the header, to store the user profile information in said database memory, and to generate an associated communication terminal identification number. Furthermore the processing means forwards the communication terminal identification number via said output means to the communication terminal.

The invention will be described in greater detail in the following by way of example only and with reference to the attached drawings, in which Fig. I shows a comparison between the Internet Architecture and the WAP
Architecture;

Fig. 2 schematically shows a connection between a communication terminal and a server according to a preferred embodiment according to the present invention, and Fig. 3 shows a flowchart over the establishment of a session according to a preferred embodiment according to the present invention.

Fig. 2 shows a wireless communication network for handling Wireless Session Protocol (WSP). The network comprises a wireless communication terminal 100, comprising an antenna 110, and an server 220 connected to a server antenna 200. The communication terminal 100 is for example an ordinary cellular phone provided with a Wireless Application Protocol (WAP). The server is provided by an operator and can handle WAP applications. The WAP comprises the WSP which the present invention is based on. How the WSP is implemented in WAP is described in detail in the Wireless Application Protocof Architecture Specification; Version 0.9; by Wireless Appiication Protocol Architecture Working Group; available from Olpen Mobile Alliance Ltd.
The server 220 includes processing means 221 or a CPU controlling the activity of the server 220. The server 220 will in general be sited at a network operator and 5 therefore not be directly connected to the antenna. Hovvever, the hardware between the server 220 and the antenna is not important to understand the invention and these parts are therefore ornitted to improve the clarity of the invention.
The server receives the request via input means 224. The processing means 221 looks for a heading containing user profile information or a communication terminal
10 identification number in the request.

If the request contains a heading containing user profile information this information is stored in a database memory 222 for use when the server 220 replies. If the request contains a communication terminal identification number the corresponding user profile information is recalled from the database memory 222 when the request is replied to. The server 220 is ready for responding the processing means 221 transmits the response via output means 223 to the communication terminal 100 via said output.

When using a connectionless WSP session, it is not possible to store WSP
headers as a part of a session state at both ends of the connection peers, i.e.
between the terminal 100 and the server 220. Therefore, all headers must be re-sent every time a WAP user agent requests a resource from the server 220 via a WAP proxy. Over a low bandwidth, high latency bearer, such as Short Messaging Services (SMS), this leads to an unacceptable overhead (only 50 - 75 % of the data sent is pay-load). The present invention solves this problem by using a cookie for storing session headers on the server within the user agent profile (uaprof) resource file defined by WAP. The idea is, that a request of data 120, conveys headers to the server 220, after which the user
11 . -agent (client) uses a file-handle to reference the information stored on the server. It is also possible for the operator to provide some pre-defined file-handle in the communication terminal, i.e. the operator has some cookies on the server. Therefore, it is not always necessary for the user agent to define a header, which saves a lot of time for the user agent.

If the operator has provided some cookies on the server, the method is disclosed by the following steps by reference to Fig.2:
the communication terminal 100 initiates a session by forwarding a request 120 of data to the server 220, the request 120 comprises an identification of the requested data and a communication terminal identification number provided by the server 220;
the server 220, when receiving the request 120 containing a communication terminal identification number, recalls user profile information from an associated database memory (not shown) corresponding to the communication terminal identification number, and said user profile information indicates a data format which will be handled by the communication terminal 100; and the server 220 repiies 130 to the request by forwarding the requested data 120 in the format defined by the user profile information.
the communication terminal can initiate a session comprising a header in a request 140 indicating the data format which can be handled by the communication terminal 100;
the server 220, when receiving the request 140 containing a header, can derive the user profile information from this header and store the user profile information in said database memory and generate an associated communication terminal identification number; and the server 220 can forward the communication terminal identification number in a reply 150 to the communication terminal 100.
12 As an alternative method of the invention, which does not require the server to have pre-defined cookies is disclosed by the folfowing steps by reference to Fig.2:
the communication terminal 100 initiates a session by forwarding a request 140 of data to the server 220, the request 140 comprises an identification of the requested data and a header indicating the data format which shall be handled by the communication terminal 100;
the server 220 upon receipt of the request 140 generates a communication terminal identification number and stores said header associated with said communication terminal identification number;
said server 220 replies 150 to the request by forwarding the requested data and the communication terminal identification number to the requesting communication terminal 100;
the communication terminal 100 stores the communication terminal identification number in a memory (not shown).

Further, when the communication terminal 100 once again initiates a session, and forwards a request 120 of the same data as in the first step, the request 120 includes an identification of the requested data and the communication terminal identification number received from the server 220. When the server 220 receives the request 120, it recalls the header from the database memory which corresponds to said communication terminal identification number, and replies 150 to the communication terminal 100.

In both of the methods it is possible for the server to define a period of time in which the user profile information can be stored in the database memory. It is also possible for the server to delete the user profile information from the database memory upon expiration of the defined period of time. The time may for example be 3 hours or 3 days. The period of time may be differentiated in dependence of the kind of subscription the user has. In order WO 99/56431 PCT/EP99/02844 '
13 to avoid double use of the same communication terminal identification number the server informs the communication terminal about the duration of this period, whereby the terminal knows when the period has expired. When the period has expired and the communication terminal starts a new session it has to transfer the user profile once more. When the server has stored the user profile information once more it provides the communication terminal with a new communication terminal identification number that uniquely identifies the communication terminal for a new period.

The header data structure used by the terminal and the server comprises a sequence of header fields, followed by e.g. image-type-specific data and actual image data. The header field comprises an image type identifier of a multi-byte length (TypeField), an octet of general header information (FixHeaderField), followed by zero or more extension header fields (ExtField).
The extension headers may be of type binary 00 through binary 11. A header of Type 00 could e.g. indicate a multi-byte bitfield used to specify additional header information. The first bit may be set if a type 00 extension header is set if more data follows. A header of the Type 11 indicates a sequence of parameter/value pairs. These can be used for optimisations and special purpose extensions, e.g., animation image formats. The "parameter size" tells the length (1-8 bytes) of the following parameter name. The "value size" gives the length (1-16 bytes) of the following parameter value. The concatenation flag indicates whether another parameter/value pair will follow after reading the specified bytes of data. The actual organisation of the image data depends on the image type.

Fig. 3 shows an example of the establishment of a session in accordance with the present invention. The session uses the Wireless Session Protocol, which is to be established between a wireless communication terminal and a corresponding server, START 300.. The communication terminal initiates a
14 session by forwarding a request of data to the server, "FORWARD
REQUEST" 310. This request comprises an identification of the requested data and a header indicating the data format, which shall be handled by the communication terminal. If the server does not receive the request, it could be possible to forward a new request, "RECEIVED REQUEST?" 320. When the server has received the request, the server can check whether the identification is recognised or not, "ID UNKNOWN" 330, i.e. if the identification has been stored on the server as a communication terminal identification number or not. If the identification of the terminal is recognised, then the server recalls user profile information from an associated database memory corresponding to the communication terminal identification number. The user profile information indicates a data format which shall be handled by the communication terminal. The server sends a reply to the request by forwarding the requested data in the format defined by the user profile information, "SEND REPLY" 340. Thereafter, the session can be ended by the user, "END" 345.

If the identification of the terminal is not recognised, "ID UNKNOWN" 330, then the server upon receipt of the request generates a communication terminal identification number, "GENERATE ID" 350. Thereafter, the server stores the header associated with said communication terminal identification number, "STORE HEADER" 360. The server replies to the request by forwarding the requested data and the communication terminal identification number to the requesting communication terminal, "SEND REPLY + ID" 370.
Finally, the communication terminal stores the communication terminal identification number in a memory, "STORE ID" 380. Thereafter, the user may choose to end the session, "END" 345.

Once the communication terminal identification number has been stored, "STORE ID" 380, it can be possible for the communication terminal to initiate further sessions, by simply forwarding a request to the server which may include both an identification of the requested data and the communication terminal identification number received from the server. Then it would be possible for the server, upon reception of a request, to recall the header from 5 the database memory which corresponds to the communication terminal identification number.
