Abstract

The invention discloses a calling / switching-in receiving method of GSM micro-micro base stations / micro-micro-micro base stations. The method comprises the following steps: configuring a plurality of micro-micro base stations / micro-micro-micro base stations configured by adopting the same frequency in a BSC side into a logical subdistrict, distributing a subdistrict identification for the logical subdistrict, storing a mapping relation between the logical subdistrict identification and the physical identification of the micro-micro base stations / micro-micro-micro base stations in BSC, and carrying out the interaction of signals and information by using the logical subdistrict identification in the communication of the BSC and a service support node of MSC and GPRS, i.e. the MSC and SGSN donot need to know about the mapping relation between the logical subdistrict identification and the actual physical identification of the micro-micro base stations / micro-micro-micro base stations, thereby the problem of logical subdistrict management when the micro-micro base stations / micro-micro-micro base stations are applied in large scale in a network is solved.

Description

technical field

[0001] The present invention relates to mobile communication technology, in particular to a GSM (Global System for Mobile Communication, Global System for Mobile Communications) pico base station / pico base station method for receiving calls and switching in. Background technique

[0002] The logical cell management method widely used in the prior art is as follows: two or more base stations that are in continuous coverage or physically close to the same area are set as the same logical cell, and these base stations have the same BCCH (Broadcast Control Channel, broadcast Control channel) and control channel format, pilot burst, synchronization burst and BCCH are sent synchronously in the same time slot of all base stations or only by some base stations. These physical base stations need to maintain precise synchronization of frames and multiframes.

[0003] When the coverage of the base stations basically overlaps, control channel messages such as pilot burs...

Embodiment Construction

[0035] Main technical idea of ​​the present invention is as follows:

[0036] On the BSC (Base Station Controller, base station controller) side, configure several pico base stations / pico base stations with the same frequency configuration as a "logical cell", and assign a cell identity (logic CGI) to it. Using the same frequency configuration means that the pico base station / pico base station uses the same carrier frequency as its own pilot burst, synchronization burst, broadcast control channel BCCH and common control channel CCCH carrier frequency, and adopts the same control channel structure, independent The dedicated control channel SDCCH also needs to use the same radio channel structure.

[0037] The mapping relationship between the logical cell identifier and the physical identifier of the pico base station / pico base station is stored inside the BSC. BSC connects with MSC through standard A interface, and connects with SGSN (Serving GPRS Support Node, GPRS service su...
