Embodiment 1

[0071] Such as figure 1 As shown, the method for determining the handover candidate cell set in Embodiment 1 of the present invention includes the following steps:

[0072] Step 101: According to the downlink measurement results reported by the terminal, determine whether the terminal is currently in a non-dominant serving cell; if yes, go to step 102; if not, go to step 103.

[0073] Step 102: Add the neighbor cell whose corresponding downlink reception level value in the downlink measurement result is greater than the first level value to the handover candidate cell set, and the process ends.

[0074] Step 103: Add the neighboring cells whose corresponding downlink receiving level values ​​in the downlink measurement results are greater than the second level value to the handover candidate cell set, and the process ends.

[0075] In step 101, the downlink measurement result reported by the terminal includes the downlink reception level values ​​of each neighboring cell dete...

Embodiment 2

[0103] The second embodiment is a method for determining a set of handover candidate cells that belongs to the same inventive concept as the first embodiment.

[0104] Such as figure 2 As shown, the method for determining the handover candidate cell set in Embodiment 2 of the present invention includes the following steps:

[0105] Step 201: According to the downlink measurement result reported by the terminal, add the neighboring cells whose corresponding downlink reception level value in the downlink measurement result is greater than the minimum reception level value to the handover candidate cell set;

[0106] Step 202: Screen the neighboring cells in the handover candidate cell set.

[0107] In step 201, the downlink measurement result reported by the terminal includes the downlink receiving level of each neighboring cell detected by the terminal. The minimum receiving level value is a preset value, which can be adjusted according to system performance. The minimum rec...

Embodiment 3

[0132] Embodiment 3 is a kind of network side device belonging to the same inventive concept as Embodiment 1. Therefore, the implementation of Embodiment 3 may refer to the implementation of Embodiment 1, and repeated descriptions will not be repeated.

[0133] Such as Figure 4 As shown, the equipment includes:

[0134] A judging module 41, configured to judge whether the terminal is currently in a non-dominant serving cell according to the downlink measurement results reported by the terminal;

[0135]The processing module 42 is configured to, after the judging module 41 determines that the terminal is currently in no dominant serving cell, add a neighboring cell whose corresponding downlink receiving level value is greater than the first level value in the downlink measurement result to handover In the set of candidate cells, the first level value is obtained according to the preset first offset and the preset minimum receiving level value; when the judging module 41 deter...

Abstract

The invention relates to the technical field of communication, in particular to a method and equipment for determining a candidate switching cell set. According the embodiment, the method comprises the steps that whether a terminal is currently in a cell without leading services or not is judged according to a downlink measuring result reported by the terminal; after the fact the terminal is currently in the cell without the leading services is confirmed, a neighborhood with corresponding downlink receiving electrical level values larger than a first electrical level value in the downlink measuring result is added in the candidate switching cell set; after the fact that the terminal is currently not in the cell without the leading services is confirmed, a neighborhood with corresponding downlink receiving electrical level values larger than a second electrical value in the downlink measuring result is added in the candidate switching cell set. When the terminal is currently in the cell without the leading services, the terminal can be limited to be switched to the neighborhood, and ping-pong switching can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and equipment for determining a handover candidate cell set. Background technique [0002] With the development of the global mobile communication system, the application range of Small Cell base stations (small base stations) is becoming wider and wider, involving blind spot coverage, enterprise internal coverage, and home coverage. [0003] The introduction of Small Cell base stations can absorb traffic and reduce network load to a certain extent. Therefore, deploying Small Cell base stations indoors can absorb traffic and optimize network resources. In the case of large-scale deployment of Small Cell base stations, there will be both Small Cell base stations and macro base stations around the Small Cell base station. When a user terminal in a call moves within the overlapping area covered by multiple Another Small Cell base station may also be handed...
