Abstract

An application server (113) receives, from a client mobile terminal (101), a request to initiate a first client application session, as well as first client specific data, where the data comprises a first mobile terminal identifier, e.g. a mobile station integrated services digital network number and a hash code. An association is made in the server (113) of a first client session identifier with the first mobile terminal identifier. The first client session identifier is then stored in a session management database (115). Maintenance of communication between the client terminal (101) and the application session is then enabled, including receiving a communication request and verifying that the communication request originate from the first client terminal (101).

Claims

1. A method of client session management in an application server (113) capable of communicating via a connectionless communication protocol with at least one client mobile communication terminal (101) in a digital mobile communication system (105), the method comprising maintaining at least a first client session identifier being associated with a client terminal identifier.

2. A method according to claim 1, comprising the steps of

receiving, from the client terminal (101), a request to initiate a first client application session,

receiving, from the client terminal (101), first client specific data, said data comprising a first mobile terminal identifier,

associating a first client session identifier with said first mobile terminal identifier,

storing said first client session identifier in a session management database (115),

enabling maintenance of communication between the client terminal (101) and the application session, including receiving at least one communication request and verifying that said at least one communication request originates from said first client terminal (101).

3. A method according to claim 2, wherein the association of a first client session identifier with said first mobile terminal identifier includes a calculation of the first client session identifier.

4. A method according to claim 2, wherein the step of enabling maintenance of communication between the client terminal (101) and the application server (113) involves use of a time-out procedure capable of disabling communication between the client terminal (101) and the application server (113), said disabling depending on a time-out limit.

5. A method according to claim 4 wherein the communication session comprises a plurality of connection requests from the client terminal (101) and service retrievals to terminals within predefined time limit.

6. A method according to claim 2, wherein the reception of first client specific data includes reception of a mobile station integrated services digital network number and a hash code.

7. A method according to claim 2, wherein the session management depends on commands received from the client mobile communication terminal (101).

8. A method according to claim 2, wherein the application server (113) sends messages to the mobile terminal (101) which are not yet sent and changes the status of these messages as sent status in the application server (113).

9. A method according to claim 2, wherein the next available message in a list of messages is sent.

17. A computer program product comprising software instructions stored on a readable medium for execution by a processor to perform the method of claim 1.

10. A client session management system arranged to communicate via a connectionless communication protocol with at least one client mobile communication terminal (101) in a digital mobile communication system (105), the system comprising means for maintaining at least a first client session identifier being associated with a client terminal identifier.

11. A system according to claim 10, comprising means for:

receiving, from the client terminal (101), a request to initiate a first client application session,

receiving, from the client terminal (101), first client specific data, said data comprising a first mobile terminal identifier,

associating a first client session identifier with said first mobile terminal identifier,

storing said first client session identifier in a session management database (115),

enabling maintenance of communication between the client terminal (1011) and the application session, including means for receiving at least one communication request and means for verifying that said at least one communication request originate from said first client terminal (101).

12. A system according to claim 11, where the means for association of a first client session identifier with said first mobile terminal identifier includes means for calculating the first client session identifier.

13. A system according to claim 11, where the means for enabling maintenance of communication between the client terminal (101) and the application server (113) include time-out means capable of disabling communication between the client terminal (101) and the application server (113), said disabling depending on a time-out limit.

14. A system according to claim 11, where the means for reception of first client specific data includes means for reception of a mobile station integrated services digital network number and a hash code.

15. A method of client session management in an application server (113) in a digital mobile communication system (105), the method comprising the steps of:

communicating with a client mobile communication terminal (101) by subsequent connectionless communication protocol messages,

receiving a request for a service through a service application server (117) from a service application,

setting a first client session identifier being associated with a client terminal identifier based on the request,

maintaining the first client session identifier being associated with a client terminal identifier of said client mobile communication terminal (101), wherein said session identifier indicates the session with said client terminal between the subsequent messages.

16. A method according to claim 15, wherein at least part of a service of the service application is retrieved from the service application to the application server (113) and the session identifier is the same during the communication both between the client terminal (101) and the application server (113) and the client terminal (101) and the service application through the service application server (117).

18. A computer program product comprising software instructions stored on a readable medium for execution by a processor to perform the method of claim 15.
