Embodiment 1

[0040] An embodiment of the present invention provides a trunking dedicated communication system, figure 1 It is a schematic diagram of the system architecture of the trunking dedicated communication system in the embodiment of the present invention, see figure 1 As shown, the communication system includes: user equipment 11 and base station 12 . Wherein, the base station 12 governs multiple cells, and the user equipment 11 may reside in these cells.

[0041] In the embodiment of the present invention, the cluster private network may be a wireless communication network with the function of Isolated E-UTRAN Operation for Public Safety (IOPS, Isolated E-UTRAN Operation for Public Safety), and the base station 12 in the network is When the loop is interrupted or the loop fails and the signaling and data cannot be transmitted normally, a certain level of communication service can still be provided for the cluster users; the user equipment 11 can be a smart phone, a tablet compute...

Embodiment 2

[0095] At present, the 3GPP protocol has made detailed regulations on the implementation of ANR. At the initial stage of network construction, there is no neighbor relationship in the neighbor relationship list, and all the handover target cells reported by the user equipment are missing neighbors. The base station guides The user equipment reports the neighbor cell PCI, and schedules appropriate idle time to allow the UE to read the ECGI of the new cell and add it to the neighbor cell list.

[0096] The problems existing in the ANR configuration in the prior art will be analyzed with specific examples below.

Abstract

The embodiment of the invention discloses a cell selection method. The user equipment in a cluster private network stores a PCI list comprising all cell PCI in the cluster private network issued by a base station in the cluster private network, the user equipment carries out cell searching, the PCI of a first strongest cell is obtained, when the PCI of a first strongest cell is inquired in the PCI list, the first strongest cell is judged as a residential cell, the reading of the system message of the first strongest cell is continued, and the cell selection is completed. On the contrary, the first strongest cell is judged as a non-residential cell, the cell selection is ended. The embodiment of the invention also discloses an automatic neighbor cell relation (ANR) configuration method, user equipment carries out cell searching, a third strongest cell is obtained, and when the third strongest cell is determined as the neighbor cell of a service cell, the system message of the third strongest cell is read directly and reported to a service base station such that the service base station carries out automatic neighbor cell relation configuration.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a cell selection method, an automatic neighbor cell relationship configuration method and equipment. Background technique [0002] At present, the cluster private network is developed to meet the needs of industry users for command and dispatch, and it is a dedicated wireless communication system for specific industry applications. The trunking private network is a private communication network independent of the public mobile communication network. In addition to providing the two-way conversation function of the mobile phone, it can also provide group (group) calls and all calls in the private network, and even establish call priority levels, and It can carry out communications such as priority calls and emergency calls that ordinary mobile phones do not have. At the same time, it can also provide special functions such as dynamic reorganization and virtual private network...
