Problems solved by technology

Some RRC messages are used to establish radio bearers, which are high-priority messages, and some messages are low-priority messages, such as measurement control messages and some measurement report messages. The mixed transmission of the two messages may result in high-priority messages. Class messages cannot be transmitted in time

Embodiment Construction

[0035] The core of the present invention is to process the transmission of RRC layer messages with priority.

[0036] The present invention mainly adopts following several implementation modes in the realization process:

[0037] (1) Add an RLC entity on the basis of the existing DCCH structure, and provide a new SRB for transmitting RRC messages on the RLC entity, so that it cooperates with the original SRB for transmitting RRC messages so that RRC messages are transmitted in Different priorities can be distinguished during transmission;

[0038] (2) RRC indicates the priority of each RRC message to be transmitted to RLC2 used to transmit the RRC message, and RLC2 preferentially transmits the RRC message of high priority to the MAC (Media Access Control) layer;

[0039] (3) When the RRC layer has multiple messages to be transmitted and needs to be submitted to the RLC2 for transmission at the same time, the RRC layer first submits the high-priority RRC message to the RLC2 to...

Abstract

This invention relates to a method for transmitting radio resource control information in the communication system including: first of all, determining the PRI information of the RRC messages in the communication system, then, transmitting high prior RRC messages firstly in the DCCH, in which, the realization of this invention enables the RRC layer information in the radio communication system to be transmitted hierarchically, the RRC of the high priority is sent first and the RRC layer information of low priority is sent after the high priority information is sent so as to secure that information of high priority is sent timely.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method for sending RRC (Radio Resource Control) messages in a communication system. Background technique [0002] In the existing 3GPP (Third Generation Partnership Project) protocol, there are four DCCHs (Dedicated Control Channels) carrying RRC messages, such as figure 1 As shown, the numbers are 1, 2, 3, and 4 respectively, and the four channels are respectively RLC1 (RLC, radio link control), RLC2, RLC3, and RLC4. In the control plane, the service provided by the RLC to the upper layer is SRB (Signaling Radio Bearer), that is, SRB1, SRB2, SRB3 and SRB4 are provided respectively. [0003] The four DCCHs carry RRC messages according to the following criteria: [0004] SRB1 is used for all messages sent on DCCH and RLC-UM (Radio Link Control in Unacknowledged Mode); [0005] SRB2 is used for all messages sent on DCCH and RLC-AM (radio link control in a...
