A method for activation release of PDF context and its device

Abstract

This invention discloses one method to remove activating PDP message, which comprises the following steps: receiving the remove message of activation PDP message sent by receive user device; judging whether to remove the PDP address same with designed PDP content in activation status all PDP message; if yes, then finding out all the same PDP address in activation status; removing the found PDP message composed of designed PDP message. This invention also discloses one device to remove activation PDP message.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for deactivating a PDP context in a GPRS or WCDMA system. Background technique [0002] GPRS or WCDMA system network structure such as figure 1 As shown, it includes the radio access network UTRAN and the core network CN, where the radio access network handles all wireless-related functions, while the core network handles all voice calls and data connections in the system, and realizes communication with the external network (External Network) switching and routing functions. The UE is user equipment, which performs data interaction with the wireless access network, and provides users with various service functions in the circuit domain and packet domain. [0003] Subdividing the UE can be divided into two parts: TE and MT. TE is a specific application module, including a specific application program APP, and MT is a communication interface module. TE i...

Problems solved by technology

[0006] Due to the limitation of the existing AT command function, when the user equipment side generates the deactivation PDP context message, a message will be generated for each PDP context that is inquired, and the network side will receive multiple messages, and Each message must be executed, that is to say, a deactivation process must be performed for each PDP context that uses the same address during the deactivation operation, so it is necessary to perform multiple deactivation processes, and one deactivation process requires multiple Signaling interaction between secondary devices, including inside the core network, inside the access network, inside the user equipment, and between the user equipment and the core network through the wireless access network, thus resulting in a slow response speed of the communication system and reducing the communication speed. equipment efficiency
