Problems solved by technology

In this way, when the base station side cannot know the equivalent frequency band information of the adjacent cell, and the terminal does not support the main frequency band, it is impossible to determine whether the terminal can switch to the adjacent cell when judging whether to perform handover based on the frequency band information supported by the terminal itself.
If the adjacent cell does not support the equivalent frequency band, the terminal will fail to handover; if the adjacent cell supports the equivalent frequency band, but the base station cannot initiate the handover when it cannot know the equivalent frequency band information of the adjacent cell, then the user service will be interrupted, thus Affecting the quality of service (Quality of Service, QOS) of user business

Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] figure 1 A schematic diagram of the implementation flow of a method for obtaining frequency band information of adjacent cells provided by an embodiment of the present invention, as shown in figure 1 As shown, a method for obtaining adjacent cell frequency band information provided in this embodiment includes:

[0062] Step 101, sending a request for CGI measurement configuration and reporting of adjacent cell frequency band information;

[0063] Here, before the sending of the CGI measurement configuration, the method further includes: a PCI measurement task, and receiving the reported unknown PCI;

[0064] Correspondingly, the reported CGI of the neighboring cell and the frequency band information of the neighboring cell are the CGI and frequency band information of the unknown PCI.

[0065] Here, the frequency band information of ...

Abstract

The invention discloses a method for obtaining the neighbor frequency band information, and the method comprises the steps: transmitting a request of CGI (Cell Global Identifier) measurement configuration and neighbor frequency band information uploading; receiving an uploaded neighbor CGI and the neighbor frequency band information. The invention also discloses the other method for obtaining the neighbor frequency band information, a method for mobile management and a device corresponding to the above methods at the same time.

Description

technical field [0001] The present invention relates to automatic neighbor relation (Automatic Neighbor Relation, ANR) technology, in particular to a method and device for acquiring frequency band information of neighboring cells and mobility management. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) protocol architecture, the physical frequency of the Long Term Evolution (LTE) system is divided into different multiple frequency bands, each frequency band corresponds to a frequency, and some frequency bands There is the same physical frequency point between them. A cell can support one main frequency band, and can support multiple equivalent frequency bands at the same time, and these equivalent frequency bands and the main frequency band of the cell have overlapping physical frequency points. In this way, it can be guaranteed that even if the terminal supports the equivalent frequency band but not the main frequency band, It can also access ...
