Embodiment 1

[0037] A method provided by the invention is used to manage the baseband resource pool of the GSM system. Such as figure 1 Shown is the structural block diagram of the GSM system baseband resource pool management system that the present invention provides, and this system comprises baseband resource pool 100 (abbreviation baseband pool, is made up of 4 GBP boards), cell radio frequency device 200, IQ switching channel 300 and baseband pool management device 400 (such as figure 1 shown in the dashed box). Each baseband unit (such as 101-108) in the baseband pool 100 represents a baseband resource for processing a carrier frequency wireless channel, and these baseband units have equal status. The radio frequency units (such as 201-204) contained in the radio frequency device 200 of the cell are pre-assigned with frequency point information and priority, and the priority is configured according to different business needs, for example figure 1 Medium priority decreases gradual...

Embodiment 2

[0054] Another method provided by the present invention is used to manage the baseband resource pool of the GSM system. In order to avoid the rapid increase of initial dynamically allocated signaling traffic caused by large traffic volume, baseband resources can be allocated in advance according to the average traffic volume, for example, in the station type of S444 (three 4 radio frequency cells), pre-allocate S222 (3 2 radio frequency cells), that is, 3 cells with 4 radio frequency units controlled by a certain base station, and each cell is pre-allocated only baseband resources of 2 radio frequency units including BCCH radio frequency, including BCCH baseband resources.

[0055] In this embodiment, the BSC uses the baseband pool management device 400 to realize the method flow of GSM system baseband resource pool management as follows: image 3 shown, including the following steps:

[0056] Step 600: Pre-allocating and activating two or more radio frequency units including...

Abstract

The invention provides a management method for a GSM system baseband resource pool and a system thereof. The core of the management method is that baseband resources are distributed dynamically according to the calls of a user, namely just BCCH baseband resources are distributed in advance at communities before the baseband resources are distributed dynamically one by one based on the unit of the carrier frequency with the initiation of the calls of the communities and the gradual increase of the services, and the baseband resources are released one by one based on the unit of carrier frequency with the gradual reduction of the services of the communities; the baseband resources can be distributed in advance according to the average traffic in order to prevent high traffic from causing the flow of the signals initially distributed dynamically to grow quickly; the mutual backing-up of GBP single boards can be formed, the disaster recovery capability of the GBP single boards is improved and the baseband resources are optimized in combination with the advantages of the static distribution and dynamic distribution.

Description

technical field [0001] The present invention relates to a resource management method and system of a digital mobile communication system, in particular to a baseband resource management method and system of a Global System for Mobile Communications (GSM, Global System for Mobile Communications). Background technique [0002] In the field of new-generation communication equipment manufacturing, remote radio systems are gradually attracting attention. The typical architecture is to divide the base transceiver station BTS into two parts: BBU (Baseband Unit, baseband unit) + RRU (Remote Radio Unit, remote radio frequency unit). The BBU is composed of a baseband processing board (GBP, Baseband Process). Multiple baseband resources are gathered together to form a baseband resource pool, which can be shared by multiple RRUs; the RRU provides the radio frequency processing function of the signal. The connection constitutes the remote radio system architecture. Compared with the tr...
