Method for communication switch, method, base station, terminal and system for obtaining neighboring district

Abstract

The embodiment of the invention discloses a communication switching method, an adjacent subdistrict obtaining method, a basic station, a terminal and a system thereof, belonging to the communication field. The method comprises the following steps: adjacent subdistrict list information is transmitted to the terminal, and the adjacent subdistrict list information comprises a plurality of pseudo noise offsets; pilot frequency intensity information transmitted by the terminal is received, and the pilot frequency intensity information comprises at least one group of searched pseudo noise offset assembly, wherein, the pseudo noise offset assembly includes at least two pseudo noise offsets, and the at least two pseudo noise offsets are transmitted by a basic station where the adjacent subdistrict of the current service subdistrict is positioned at the different time spans in an alternative way to the terminal; a target adjacent subdistrict corresponding to the at least group of the pseudo noise offset assembly is determined according to the incidence relation information of the stored pseudo noise offset assembly and the adjacent subdistrict; and the communication switching is carried out according to the target adjacent subdistrict. The embodiment of the invention can solve the problem of communication interruption.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for communication handover, a method for acquiring adjacent cells, a base station, a terminal and a system. Background technique [0002] Code Division Multiple Access (CDMA) air interface stipulates that the 1X system supports a maximum of 40 adjacent cells, and the DO system supports a maximum of 31 adjacent cells. In current network applications, as the number of indoor coverage sites increases, the number of adjacent cells also increases, and adjacent cells may be marked with different or the same pseudo noise (Pseudo Noise, PN) offset. When a terminal needs to switch from the current serving cell to an adjacent cell during communication, if the adjacent cells are configured with different PN offsets, the length of the adjacent cell information is insufficient, that is, the maximum number of adjacent cells that the system can support Restricted by the existing prot...

Problems solved by technology

When a terminal needs to switch from the current serving cell to an adjacent cell during communication, if the adjacent cells are configured with different PN offsets, the length of the adjacent cell information is insufficient, that is, the maximum number of adjacent cells that the system can support Restricted by the existing protocol, the terminal cannot search for adjacent cells in time, and eventually the terminal cannot switch in time, and communication is interrupted; if adjacent cells are configured with the same PN offset, the base station cannot correctly identify The adjacent cell where the terminal wants to switch, the terminal cannot switch in time, and the communication is interrupted
