Method for network service entity for managing session affairs mark and its correspondent information

Abstract

This invention provides a method for a network service entity management session matter marker and its related information. The key point is that when a TID is invalid, it is not cancelled by NAF immediately but is kept for a period of time so as to prevent the network signaling resources from waste. When a user uses said invalid TID again, NAF can design the time for keeping the invalid TID and its related information to preserve the storage load of NAF at a reasonable situation.

Description

technical field [0001] The invention relates to the technical field of third-generation wireless communication, in particular to a method for managing session transaction identifiers and corresponding information of network service entities. Background technique [0002] In the third-generation wireless communication standard, the general authentication framework is a general structure used by various application business entities to complete the verification of user identities. The application of the general authentication framework can realize the inspection and verification of users of application services identity. The various application services mentioned above can be multicast / broadcast services, user certificate services, instant information provision services, etc., or agency services, such as multiple services connected to an agent. This general authentication framework treats agents as a kind of The organizational structure can be very flexible, and the general a...

[0009] The disadvantage of the above method is: if NAF marks the invalid TID and its corresponding information as disabled, NAF needs to keep the invalid TID all the time, and the update of TID may be very frequent, then NAF needs to occupy its own effective resources to save a large number of invalid TIDs. TID, which also makes local retrieval of the TID very slow

[0010] If the NAF directly deletes the expired TID and its corresponding information, the following situation may occur: When the user uses the expired TID to request a service, because the NAF does not store the TID information locally, it has to go to the BSF for retrieval, because the TID retrieved by the NAF All of them are invalid information, which will inevitably lead to a waste of signaling resources; when many users use expired TIDs to request services, NAF will frequently go to BSF to retrieve expired TIDs, which will make the service of NAF itself The ability to decline, unable to provide services to users normally, that is, for NAF, there will be a phenomenon similar to denial of service attacks
