Problems solved by technology

[0015] Therefore, in this handover process, the user equipment's frequent measurement activities and measurement report messages for neighboring cells will consume a large amount of power of the user equipment. It is more important to save the use of power resources, but the above-mentioned mobile management process for user equipment is not conducive to saving the power of user equipment

Embodiment Construction

[0065] In the present invention, when the user equipment needs to carry out business, the measurement frequency of the neighboring cell is reduced due to the need of power saving, so its serving base station does not know its mobility in time. When the user equipment camps in a new cell due to movement or cell reselection, if it needs to send uplink data or signaling, it will send a service request message or a forward access message to the base station of the current cell, thereby triggering the current cell The base station, that is, the target base station performs the corresponding handover operation process, so that the user equipment can smoothly access the network through the target base station to carry out services. The present invention increases the flexibility of the handover process, and facilitates the selection of different handover operations in the network according to different application scenarios. processing method.

Abstract

The related mobile management method for UE comprises: when UE has no data but connects with RRC, decreasing the interaction for saving power to lead other BS can not learn UE state in time; for this condition, when UE sending up message to make target BS detect UE existence, target BS active initiates switch process for message interaction with SBS. This invention can reduce signaling interaction between UE and network for non-necessary condition to save power, and can also up transmit data for UE.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a technology for implementing mobility management of user equipment. Background technique [0002] In the current WCDMA (Wideband Code Division Multiple Access) system, when the user equipment (user equipment) in the connected state changes the cell or system where the user equipment is located, handover occurs. The purpose of handover is to deal with the over-area caused by movement in connection mode, so as to ensure the continuity of coverage. [0003] In the WCDMA system, the handover includes hard handover, soft handover, same-frequency / different-frequency hard handover and inter-system handover. [0004] In the WCDMA system, according to whether there is an RRC (Radio Resource Control) connection between the user equipment and the network, the user equipment is divided into a connected state and an idle state. The process of changing the current cel...
