Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] For achieving the above object, technical scheme of the present invention is achieved in that way:

[0034] figure 1 It is a flow chart of a method for allocating wireless network temporary identifiers in the present invention, which is applicable to the process of handover of UE from a source base station serving a source cell to a target base station serving a target cell, such as figure 1 said,

[0035] Step 101, the source base station sends a handover request message to the target base station, and the handover request message carries the cell-level wireless network temporary identifier C-RNTI of the UE in the source cell;

[0036] Step 102, the target base station receives the handover request message sent by the source ...

Abstract

The invention discloses a radio network temporary identity distributing method and system. The technical scheme provided by the invention is suitable for a process of switching UE (User Equipment) from a source cell into a target cell, wherein a source base station provides services for the source cell, and a target base station provides services for the target cell. The source base station sends a switching request message carrying a cell radio network temporary identification (C-RNTI) of the UE in the source cell to the target base station; the target base station receives the switching request message, and figures out a C-RNTI of the UE in the target cell according to a preset strategy in accordance with the C-RNTI of the UE in the source cell and cell identification information of the source cell; and the target base station sends a switching response message to the source base station, wherein the switching response message carries the C-RNTI of the UE in the target cell. The technical scheme provided by the invention can solve the problem that the mapping relationship of the C-RNTI before and after switching is individually stored and post-processed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for assigning wireless network temporary identifiers. Background technique [0002] In the LTE system, the radio network temporary identifier RNTI information is used for the UE identifier in the E-UTRAN mode of the Evolved Universal Terrestrial Radio Access Network, and is automatically allocated by the system. The value range of RNTI stipulated in the existing agreement is shown in Table 1, [0003] [0004] Wherein, a cell-level radio network temporary identifier C-RNTI is used to provide a cell-level unique identifier for a connected user. The C-RNTIs of different cells before and after the handover are assigned independently, which are generally inconsistent and have no fixed mapping relationship. Therefore, operations such as separate storage and post-processing comparison of the C-RNTI mapping relationship before and after the handover are re...
