Method for deleting wireless link under out-of-step state

Abstract

The invention relates to a method for deleting the wireless chain circuit in out-of step condition, which comprises: when the user terminal (UE) receives the RRC connection release message sent from the network, and the responding to said RRC connection release message to the network, if the UE detects that it is out-of-step, directly releasing the chain circuit between it and network and deleting all local resource relative to said chain circuit; when the network UE sends RRC connection release message, and there is no RRC connection release complete message received in some time, responded by said UE, and if the network detects the chain circuit of said UE is out-of-step, directly releasing the network resource occupied by said chain circuit; when the network receives the region refresh message about RL chain circuit failure sent by UE at the second region, and assuring that said UE is in the RRC connection release process in the first region, the network uses the second region to send RRC connection release message to UE; and after said UE receives the RRC connection release message, it releases the chain circuit between it and networks, and deleting all local resource relative to the chain circuit. The invention can reduce the electricity consumption of terminal, and reduce the signal interference on other users.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for deleting a wireless link in an out-of-synchronization state. Background technique [0002] According to the current protocol, when the user's normal call ends, the network side will send a radio resource control (RRC) connection release message to the terminal. After the RRC (UE-RRC) on the terminal side receives the message, if the UE is currently The state is CELL_DCH, and the UE will send N308 RRC connection release complete messages continuously, and the interval between each time is T308. If the RRC connection release completion message needs to be sent 8 times, and each time interval is 320ms, then UE-RRC needs to release the RL normally after 2 seconds. If the user wants to talk again during this period, he will not be able to access it. [0003] If the RL fails to be detected through the physical layer, UE-RRC releases the RL in advance is actu...

[0007] In addition, during the RRC connection release process, if the RL resource is not deleted on the user side in the out-of-synchronization state, it will have the following impact: If the network side receives the RRC connection release completion message of user 1, and the user 1's Resources (through the RB establishment process) are allocated to user 2 in the same cell. User 1 continues to use these code channels to send RRC connection release completion messages. User 2 also uses these code channels, which will cause relatively large interference to user 2.

Moreover, if the interference of user 2 increases, user 2 will increase the transmission power. Since CDMA is a self-interference system, it will inevitably affect other user signals at the same time slot in this cell. Although user 1's code channel and time slot It has been deleted on the base station side, but user 1 continues to send uplink data, and the signals of these two users may be detected on the same time slot and code channel on the base station side, so that the signal interference increases
