Method, device and system for maintaining information in adjacent region

Abstract

The invention discloses a method, a device and a system for maintaining the information in an adjacent region. In the scheme in the invention, eNB maintains the information stored in a GERAN (GSM EDGE radio access network) adjacent region according to the grouping switching capability information dynamically obtained in the GERAN adjacent region. The invention has the advantages that the eNB accurately obtains whether the GERAN region supports the grouping switching through the continuous self-learning of eNB according to the scheme provided by the invention so that the dynamic management of the information in the GERAN adjacent region is realized by the eNB; the interference degree of manpower on the list information of the adjacent region in the eNB can be reduced; the work load of network optimization personnel is reduced; and the accuracy of the list information in the adjacent region can be enhanced so as to reduce the failure rate of the switching and enhance the property of the system.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an evolved node B (eNB, eNodeB) maintenance GSM and enhanced data rate GSM evolution technology (EDGE, Enhanced Data Rate for GSM Evolution) wireless access network (GERAN, GSM EDGE Radio Access Network) neighbor cell information method and system. Background technique [0002] When a user equipment (UE, User Equipment) in a connected state moves from a current serving cell to another cell, in order to maintain the communication quality of the UE, the UE needs to be handed over to the newly entered cell. [0003] Handover includes intra-system handover and inter-system handover, that is, inter-system handover. In the initial stage of deployment of the Long Term Evolution (LTE, Long Term Evolution) / System Architecture Evolution (SAE, System Architecture Evolution) system, the typical coverage is that the traditional 2nd generation mobile communication technology (2G, Sec...

Problems solved by technology

One of the main characteristics of this manual configuration method is that it is prone to errors or deviations

For example, a certain GERAN neighboring cell can support packet switching (PS, PacketSwitched), but due to manual errors, the information of the GERAN neighboring cell is wrongly configured as not supporting packet switching; When grouping the neighbor cell information for handover, this "missing" GERAN neighbor cell will not be considered at all

[0005] In addition, when switching from the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) of the LTE / SAE system to the GERAN A / Gb interface mode (mode) of the 2G / 3G system, the source eNB The side cannot know whether the target GERAN cell supports packet handover, that is, the source eNB side cannot know the system capability of the target GERAN cell

Then, if there is a mistake in the manual configuration of the GERAN neighbor cell information in the eNB, it will easily cause the consequences of increasing the handover failure rate and reducing system performance.

For example, among the GERAN neighbor cell information configured in the eNB, if one of the GERAN neighbor cells actually does not support packet handover, but the GERAN neighbor cell is configured to support packet handover due to manual error, the UE will The information of the GERAN neighbor cell, when trying to perform packet handover to the corresponding GERAN neighbor cell, the handover will fail

For another example, when a GERAN neighboring cell of the eNB can support packet handover after its function is upgraded, then network optimization personnel are required to timely and correctly update the information of the corresponding GERAN neighboring cell of the eNB, that is, in the neighbor cell list information of the eNB, Modify the information of the GERAN neighboring cell to support packet handover, otherwise, the eNB will not provide the information of the GERAN neighboring cell to the UE performing packet handover, so the UE will not try to perform packet handover to the GERAN neighboring cell, so that the corresponding The system capacity of GERAN neighboring cells cannot be fully utilized, resulting in a waste of system resources
