Problems solved by technology

Therefore, the wireless link resource of NodeB is abnormally suspended, which will affect the subsequent wireless link establishment process
As shown in Figure 1, in the subsequent radio link establishment message, if the RNC uses the same control radio network controller (CRNC) communication context identifier (CRNCCommunication Context ID, one-to-one correspondence with the NodeB Communication Context), the NodeB will If the CRNC communication context identifier in the radio link establishment request message sent by the RNC is considered to be duplicated, the radio link establishment failure message will be returned, resulting in user call failure

Embodiment Construction

[0015] As shown in Figure 2, in the embodiment of the present invention, according to the principle of radio link establishment priority, if NodeB receives the radio link establishment request message from RNC, it finds that the UE corresponding to the CRNC communication context identifier in the message has already Existence, that is, resources have been allocated and wireless links have been established for the UE, delete all resources and all wireless links allocated for the UE in the NodeB, that is, reset the UE, and then according to the received wireless link establishment request message, in The NodeB allocates corresponding resources for the UE and establishes a radio link, and then returns a radio link establishment response to the RNC.

[0016] Below in conjunction with accompanying drawing 3, describe the specific implementation steps of the embodiment of the present invention:

[0017] Step 100, the RNC sends a wireless link establishment request message to a certa...

Abstract

A method for setting up radio link includes judging whether resource and radio link is distributed to UE or not by Node B according to communication context identification of control radio network controller in received request message of radio link build-up based on priority principle of radio link build-up , deleting distributed resource and radio link of user device and then redistributing resource and setting up radio link according to request message of radio link build-up if it is.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a node B (NodeB) subsystem in a TD-SCDMA or WCDMA system. Background technique [0002] According to the 25433 protocol standard of the TD-SCDMA system, there are strict audit procedures for public resources, such as cells, local cells, and public channels. The resource is reported to the radio network controller (RNC), and the RNC compares it with its own public resources after receiving it. If it finds that the NodeB has inconsistent public resources, it initiates a public resource deletion process. Therefore, the consistency between the public resources on the NodeB and the RNC can be guaranteed. For dedicated resources, the audit process only includes the audit of the Communication Control Port (Communication Control Port), and there is no audit for the wireless link. Therefore, once a communication abnormality or other abnormality occurs, for example, the RNC does not rec...
