Problems solved by technology

[0004] During the process of RRC connection establishment, there is a certain time waiting between the time when the message arrives at the NodeB and the time when the message is actually sent to the air interface by the NodeB, and the message will be stored in the NodeB for a period of time, so the UE may take a long time to The RRC connection establishment message is received, resulting in a long UE access or call connection time
When the wireless situation is poor and the transmission delay is large, the UE cannot even receive the message, resulting in access or call failure

Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] figure 1 It is a flowchart of a method for reducing RRC connection establishment delay provided by an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0036] In step S101, the NodeB receives and saves the data packet of the forward access channel FACH.

[0037] UE sends RRC connection request to RNC. UE sends RRC connection request message RRCCONNECTIONREQUEST to RNC, requesting to establish an RRC connection.

[0038] The RNC sends an RRC connection establishment message to the UE. After receiving the RRC connection request message from the UE, the RNC determines whether to accept or re...

Abstract

The invention discloses a method and a device for reducing RRC (radio resource control) connection delay. The method includes that a base station NodeB receives and stores a data packet of a front access channel (FACH), the NodeB analyzes the data packet, and if the data packet contains common control channel (CCCH) data, the data are sent to an air interface after the data are subjected to scheduling treatment in advance. The CCCH type data carried by the FACH are identified and subjected to the dynamic scheduling treatment selectively, so that time for UE (user equipment) receiving the RRC connection to establish information is reduced, and the problem of long access or call completion time caused by long information receiving time is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for reducing RRC connection delay when UE (User Equipment, user terminal) accesses UTRAN (UMTS Terrestrial Radio Access Network, Universal Mobile Telecommunications System Terrestrial Radio Access Network). Background technique [0002] UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) air interface technology. The UMTS system adopts a structure similar to that of the second generation mobile communication system, including RAN (RadioAccess Network, radio access network) and CN (Core Network, core network). Among them, RAN mainly refers to UTRAN, which includes one or several RNS (Radio Network Subsystem, wireless network subsystem). An RNS is composed of an ...
