Method, apparatus and system for maintaining service RL

Abstract

The invention discloses a method, apparatus and system for maintaining a service RL, and relates to the field of mobile communication systems. The method comprises the following steps: when a base station reconfigures an established DPA / UPA non-service RL of a user terminal as a DPA / UPA service RL, judging whether the user terminal is in a macro diversity state according to a macro diversity indication from an RNC; if the base station judges that the user terminal is in the macro diversity state, reporting an RL restoration message to the RNC, so that the DPA / UPA service RL falls into a macrocell; and after the DPA / UPA service RL falls into the macro cell, determining, by the base station, whether to send an RL failure message to the RNC by judging whether the RL is out of synchronizationand whether the state of the user terminal changes. By adoption of the method, apparatus and system disclosed by the embodiment of the invention, when a failure reporting condition is satisfied, no failure is reported, and the service RL of the DPA / UPA user terminal in a macro diversity uplink / downlink imbalance scene remains stable.

Description

technical field [0001] The present invention relates to the field of mobile communication systems, in particular to a method, device and system for maintaining a service radio link (Radio Link, RL). Background technique [0002] After the 3rd Generation Partnership Project (3GPP) protocol introduced High Speed ​​Downlink Packet Access (HSDPA) technology in R5, the service types of users accepted in the downlink direction of the base station are more abundant, such as R99 Business, there is HSDPA business, HSDPA business has greatly improved the user's downlink data rate. After 3Gpp introduced the High Speed ​​Uplink Packet Access (HSUPA) technology in R6, the service types of users accepted in the uplink direction of the base station are more abundant, including R99 service and HSUPA service, and the HSUPA service greatly improves the user's uplink data. rate. [0003] The unbalanced uplink and downlink of soft handover scenarios, especially the macro-micro handover enviro...

AI Technical Summary

Problems solved by technology

Because the downlink quality of the macro cell is much better than that of the micro cell, the user equipment (User Equipment, UE) immediately reports the 1a event (this event will trigger handover to increase the RL), the 1d measurement event (this event will trigger the change of the serving cell), and the serving RL Switching back to the macro cell, the macro cell is prone to wireless link failure or failure, and the service RL cannot be stably established in the macro cell, resulting in Downlink Packet Access (DPA) DPA / Uplink Packet Access (Uplink Packet Access) Access, UPA) user rate drop, or even call drop, poor user experience
