Problems solved by technology

[0019] In this technology, when the destination MME does not choose a new one but still uses the old Serving SAEGW, the source MME will also initiate a delete user context request to the old Serving SAE GW, which will cause the old Serving SAE GW to be related to the user resources were released by mistake
In this scheme, the source MME cannot know whether the destination MME has selected a new Serving SAE GW

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as image 3 As shown, this embodiment includes the following steps:

[0036] Step 301, the destination MME judges whether to use the old Serving SAE GW or reselect a new Serving SAE GW;

[0037] Step 302, if the destination MME judges to select a new Serving SAE GW, then the destination MME sends a delete context request to the old Serving SAE GW;

[0038] In step 303, after the old Serving SAE GW releases the user resource, it returns a context delete response to the destination MME.

[0039] In step 302, after the target MME judges that a new Serving SAE GW is selected, before the target MME sends a delete context request to the old Serving SAE GW, the target MME sends a bearer establishment request to the new Serving SAEGW; the new Serving SAE GW allocates the relevant bearer resource, after the bearer is established, return...

Abstract

The invention discloses a method for preventing wrong release of resources in updating or switching process in a tracking area, which comprises that: an objective MME judges whether to use an old Serving SAE GW or reselect a new Serving SAE GW; if the objective MME judges to choose the new Serving SAE GW, the objective MME sends a request of deleting context to the old Serving SAE GW. Since the objective MME knows whether to use the old Serving SAE GW or reselect the new Serving SAE GW, the objective MME does not send deleting request when using the old Serving SAE GW and only sends the deleting request when selecting the new Serving SAE GW, thereby solving the problem of wrong release of resources in source Serving SAE GW and guaranteeing successful updating or switching.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for avoiding wrong release of resources during tracking area update or handover. Background technique [0002] With the sudden emergence of Wimax (World Interoperability for Microwave Access, the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. cost. Therefore, the standardization working group of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is currently working on researching PS Core (Packet Switch Core, packet switching core network) and UTRAN (Universal Mobile Telecommunication System Radio Access Network, The evolution of the Global System for Mobile Communications Radio Access Network), this research topic is called System Architecture Evolution (SAE for short), the...
