Communication system and method for building/deleting communication context

Abstract

The invention relates to a communication system, which comprises: a mobile terminal with the first access layer signaling treatment module to the second one, a base station controller with a second layer signaling treatment module, a central control module to connect with the second A interface signaling treatment module through the first A interface signaling treatment module, and a second non-access layer information treatment module connected to said second access layer signaling treatment module, central control module and first A interface signaling treatment module; and a kernel network system. It also provides a method to build / upgrade / cancel communication context. This invention simplifies business build process and time, and releases network load.

Description

technical field [0001] The present invention relates to a communication system and a method for establishing / deleting a communication context, in particular to a base station controller that can replace a mobile terminal and interact with a core network system to realize processing of non-access stratum signaling, including the base station controller A communication system and a method for establishing a communication context in the communication system. Background technique [0002] When a mobile terminal (User Equipment, referred to as UE) initiates a service request, the UE first needs to establish an access layer (Radio Resource Layer, referred to as RR layer) connection with a base station controller (Base Station Controller, referred to as BSC), and the BSC communicates with the RR layer order, and provide a connection channel from the UE to the core network, so that it can establish a non-access layer (Layer 3, L3 layer for short) connection with the core network sys...

Problems solved by technology

[0003] It can be seen from the above technical solution that since the existing BSC cannot perform any processing on the L3 layer signaling, the processing of each L3 layer signaling requires at least one interaction between the CN and the UE, that is to say, the BSC needs to transfer at least two Subsequent to the L3 layer signaling, thus increasing the amount of signaling transmitted over the air interface

When the UE changes from the idle state to the connected state, a large amount of similar L3 layer signaling needs to be exchanged between the UE and the CN, and the transfer of each signaling needs to go through the air wireless transmission between the UE and the BSC and between the BSC and the CN The wired transmission between the BSCs also includes the forwarding process in the middle of the BSC, which occupies the bandwidth of wired transmission and wireless transmission and increases the network burden; in addition, it also prolongs the time for UE state transition, wasting the time of the UE user , and it may also give up the opportunity to contact other UE users, which will bring great inconvenience to UE users
