Problems solved by technology

These two C-RNTIs need to be transmitted during the two processes of the handover request response from the target base station to the original base station and the handover command from the original base station to the terminal, and the length of the C-RNTI is 16 bits. Obviously, doing so will occupy more RRC signaling resource

Embodiment Construction

[0022] During the handover process of the terminal from the original base station to the target base station, it is necessary to initiate a random access process to the target base station, during which the target base station will allocate a temporary C-RNTI (Temporary C-RNTI) for the terminal; When the terminal has the persistent scheduling service, the temporary C-RNTI is used as the persistent scheduling C-RNTI, without the target base station assigning the persistent scheduling C-RNTI to the handover user through RRC signaling. In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0023] Since the solution of the present invention involves the random access process, firstly, the non-contention random access process and the contention random access process in handover are introduced. The process of contention for random access ...

Abstract

The invention discloses a method and a system for distributing persistent scheduling cell-radio network temporary identities (C-RNTI) during terminal switching. The method comprises the following steps that: a target base station judges whether a persistent scheduling C-RNTI is needed to be distributed to a terminal according to switching request information from an original base station and a admission control process of the target base station; and if the persistent scheduling C-RNTI is needed to be distributed to the terminal, the target base station and the terminal updates a temporary C-RNTI distributed in a random access process into a persistent scheduling C-RNTI. The invention also discloses a system for realizing terminal switching. The scheme of the invention can reduce radio resource control signaling load during terminal switching.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and system for allocating a cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI) for continuous scheduling when a terminal is switched. Background technique [0002] In the Long Term Evolution (LTE) system, resource scheduling is divided into persistent scheduling and dynamic scheduling. Persistent scheduling means that the base station allocates fixed resources (the resources include time, frequency, code channel, etc.) to data packets of a certain service and specifies a fixed transmission format, and the data packets are sent in the specified transmission format at the specified resource location. The base station indicates the occurrence cycle of persistent resources through radio resource control (Radio Resource Control, RRC) signaling, and specifies the resource and transmission format of persistent schedul...
