Problems solved by technology

[0003] In the EPS network, the IP address of the UE is generally dynamically allocated by the Packet Data Network Gateway (P-GW). It is assigned to another UE. However, since ANDSF cannot perceive the change of the UE state, it still records the context of the original UE. Therefore, when ANDSF sends data according to the recorded IP address, it may send the data to a wrong UE.
In the process of implementing the present invention, the inventor found that the prior art has the following problems: after the UE state changes, because the ANDSF cannot perceive the UE state change in time, and thus cannot delete the invalid UE context in time, resulting in garbage data recorded in the ANDSF Too much, it is also possible to send data to the wrong UE

Embodiment Construction

[0031] Embodiments of the method for processing UE context in the present invention include:

[0032] Step A: ANDSF receives the deletion indication message after the UE state changes. Wherein, the deletion instruction message may be sent by the UE to the ANDSF after the state changes, or may be generated by the ANDSF after not receiving a response from the UE (for details, please refer to the following method embodiment 1), or may be sent by the wireless network device in Send it to the ANDSF after learning that the state of the UE has changed (for details, refer to the second method embodiment below).

[0033] Step B: ANDSF deletes the UE context corresponding to the UE according to the deletion indication message.

[0034] The technical solution of the present invention will be described in further detail below with reference to the drawings and specific embodiments.

[0035] see figure 1 , a schematic network structure diagram provided for Embodiment 1 of the method for...

Abstract

The invention discloses a method and a device for processing user equipment context. The method for processing user equipment context comprises the following steps that: an access-network discovering-selecting functional entity receives a deletion-indicating message after the state of user equipment changes; and the access-network discovering-selecting functional entity deletes user equipment context corresponding to the user equipment according to the deletion-indicating message. The device for processing user equipment context comprises the user equipment, wireless network equipment and the access-network discovering-selecting functional entity corresponding to the method. The embodiment of the invention can enable ANDSF to delete invalid UE context in time, thereby avoiding the problems of storing excessive waste data and sending data to wrong UE.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for processing user equipment context. Background technique [0002] In order to meet the challenges of wireless broadband technology, Long Term Evolution (LTE) defines a new communication network architecture - Evolved Packet System (EPS), EPS integrates multiple access methods, Including 3GPP access, trusted non-3GPP access, and untrusted non-3GPP access. After user equipment (User Equipment, UE), or called user equipment, accesses the network, the access network discovery and selection functional entity (Access Network Discovery and Selection Function, ANDSF) in the network collects network status information of the access network, such as Load status, etc., according to the relevant policies of the operator, such as the access mode available to the UE, send the access network information and handover policy to the UE, and the UE wil...
