example 1

[0069] like image 3 As shown, the flow of the specific implementation method includes the following steps:

[0070] Step 301 , if the UE in the connected state needs to modify the RRC connection during the service process, the E-UTRAN (evolved terrestrial radio access network) sends an RRC connection reconfiguration message to the UE.

[0071] Step 302, UE processes according to relevant fields in the RRC connection reconfiguration message. The specific implementation process is as follows:

[0072] If the reconfiguration failure is caused by an exception in one of measConfig (measurement configuration), dedicatedInfoNASList (non-access stratum dedicated information list) or radioResourceConfigDedicated (radio resource configuration specific meaning), use 000, 001, 011 respectively express. Finally, the reconfiguration failure cause value is encapsulated into an RRCConnectionReestablishmentRequest (RRC connection reestablishment request) message and sent to the network sid...

[0078] like Figure 4 As shown, the flow of the specific implementation method includes the following steps:

[0079] Step 401, if the UE in the connected state needs to modify the RRC connection during the service process, the E-UTRAN sends an RRC connection reconfiguration message to the UE.

[0080] Step 402, UE processes according to relevant fields in the RRC connection reconfiguration message.

[0081] The specific implementation process is as follows:

[0082] If the reconfiguration failure is caused by an exception in the configuration of a certain item in mobilityControlInfo or SecurityConfigHO, it is indicated by 001 and 100 respectively. Finally, the reconfiguration failure cause value is encapsulated into the RRCConnectionReestablishmentRequest message and sent to the network side.

[0083] Step 403, when the network side receives the RRCConnectionReestablishmentRequest (RRC connection reestablishment request) message, the decision processing unit of the network...

[0087] like Figure 5 As shown, the flow of the specific implementation method includes the following steps:

[0088] Step 501, if the UE in the connected state needs to modify the RRC connection during the service process, the E-UTRAN sends an RRC connection reconfiguration message to the UE.

[0089] Step 502, UE processes according to relevant fields in the RRC connection reconfiguration message. The specific implementation process is as follows:

[0090] If the reconfiguration fails due to handoverFailure or otherFailure, etc., it is indicated by 101, 110, and 111 respectively. Finally, the reconfiguration failure cause value is encapsulated into the RRCConnectionReestablishmentRequest message and sent to the network side.

[0091] Step 503, when the network side receives the RRCConnectionReestablishmentRequest message, the judgment processing unit of the network side judges the ReestablishmentCause value in the message.

[0092] The judgment process at the network sid...

Abstract

The invention relates to a system and method for processing failure of radio resource control (RRC) connection reconfiguration. The method is characterized in that the specific failure cause value is added at the user equipment (UE) terminal according to the specific cause of failure of RRC connection reconfiguration, then the failure cause value is encapsulated in a RRC connection reestablishment request message and the request message is sent to the network terminal, namely the evolved universal terrestrial radio access network (E-UTRAN), and the network terminal receives the RRC connection reestablishment request message, learns that the RRC connection reconfiguration process fails, analyzes the specific failure cause value encapsulated in the RRC connection reestablishment request message, carries out judgment according to the convention rule of the UE terminal and initiates RRC connection reconfiguration or RRC connection reestablishment. The technology in the invention reduces the realization complexity of the RRC connection reconfiguration process and improves the connection efficiency.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a radio resource control (RRC, Radio Resource Control) connection reconfiguration technology in a long-term evolution (LTE, Long Term Evolution). Background technique [0002] A mobile communication system full of vitality can be continuously enhanced with the increase of human needs, providing users with higher data rates, and providing networks with wider coverage and greater capacity. The main performance goals of 3GPP LTE include: providing a peak rate of 100Mbps downlink and 50Mbps uplink in a 20MHz spectrum bandwidth; improving cell edge user performance; increasing cell capacity; reducing system delay —— The internal one-way transmission delay of the user plane is less than 5ms, the transition time of the control plane from the sleep state to the active state is less than 50ms, and the transition time from the resident state to the active state is less than 10...
