Problems solved by technology

[0014] 2. The entire wireless network subsystem will fail when the base station controller is upgraded
[0015] 3. During network expansion, it is necessary to cut some base stations from the original home base station controller to the new home base station controller. It is necessary to manually modify complex configuration information to change the ownership relationship between the base station and the base station controller.
Moreover, the manual operation process is complex, time-consuming and error-prone, which can easily cause adverse effects on the normal operation of the network.

Embodiment 1

[0064] Please refer to Figure 3 and Table 1-Table 6. When the base station controller fails, in order to reconnect the base station controlled by the failed base station controller to other normal working base station controllers to continue to provide services, it is controlled by the reorganization controller Wireless access network reorganization, the reorganization process includes:

[0065] The operating status of the base station controller 1 is monitored by the reorganization group controller through the heartbeat protocol between it and the base station controller 1 . Once the reorganization controller detects that the base station controller 1 fails, the reorganization controller updates the status of the base station controller 1 as unavailable in the configuration database, so as to prevent the base station controller 1 from being reselected as the home base station controller of other base stations.

[0066] The reorganization controller queries the ID of the affec...

Embodiment 2

[0077] In this embodiment, the heartbeat protocol between the base station and the base station controller is used to detect the operation state of the base station controller, instead of the method of using the recombined controller to detect the operation state of the base station controller in the first embodiment.

[0078] For example, base station 1 monitors the operation status of base station controller 1 through the heartbeat protocol between it and base station controller 1. When base station controller 1 fails, base station 1 sends a report message to the preset reorganization controller, and the report message carries ID of base station 1 and ID of base station controller 1. The report message sent by the base station 1 may also carry the ID of the new home base station controller 2 expected by the base station 1 . The recombination controller responds to the report message of base station 1 after receiving the report message of base station 1 .

[0079] If base st...

Embodiment 3

[0088] Still taking the contents of Table 1-Table 6 as an example, in the wireless access network architecture of Figure 3, when the network administrator needs to reconnect one or some base stations to other base station controllers, the network administrator will Input the ID of the base station whose ownership relationship is to be changed, its home base station controller ID, and the desired new home base station controller ID, and the OMC sends a reorganization command to the reorganization controller through the interface X3. Wherein, the reorganization command sent by the OMC must carry: the ID of the base station whose ownership relationship is to be changed, the ID of the original base station controller and the expected new ID of the base station controller.

[0089] For example, when the network administrator needs to modify the original home base station controller 1 of base station 1 in the wireless access network to the new home base station controller 2, as shown...

Abstract

This invention relates to a regroup method, a system and a controller of a radio access network set with an operation and maintenance center, a base station controller and a base station, in which, the controller is set in the net to control regroup of the network, which includes: a regroup controller selects a new attribution controller for the base station and modifies the configured information for the controller and the base station accesses a new attritution controller, which can automatically put a base station of a subsystem of the original radio network under the control of a base station controller working normally to continue providing service to users in the sphere covered by the original one.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a wireless access network reorganization method, system and recombination controller. Background technique [0002] The architectures of the radio access networks of the second generation mobile communication systems (such as GSM and IS95) and the third generation mobile communication systems (such as 3GPP WCDMA R99 and 3GPP2CDMA20001x) are tree-like hierarchical structures. The base station is the leaf node at the bottom layer, and the base station controller is above the base station. The base station is mainly responsible for the physical layer of the air interface, such as intermediate frequency signal and baseband signal processing, and radio frequency signal transmission / reception. The base station controller is mainly responsible for the second and third layer processing of the air interface. [0003] One base station controller manages one or more base stations, and ...
