Embodiment 1

[0070] FIG. 3-FIG. 4 show the backup process according to the first embodiment of the distributed storage structure of the present invention.

[0071] First, the process of global backup is described in detail in conjunction with FIG. 3 .

[0072] Step 1, the SCM main board receives the all resource backup message sent by the OM, packs all the resources stored on it in a certain format and sends it to the hot backup driver module;

[0073] Step 2, the SCM standby board receives the data packet sent by the hot backup driver module, unpacks it, and then modifies the corresponding resource according to the backup data;

[0074] Step 3: After all backups of the SCM standby board are completed, a backup success response message is sent to the OM of the SCM standby board.

[0075] Next, the incremental backup process will be described in detail in conjunction with FIGS. 3 and 4 .

[0076] The incremental backup process is included in the specific NBAP process, which is divided int...

Embodiment 2

[0099] FIG. 5 shows a second embodiment of the data backup method of the distributed storage structure of the present invention.

[0100] It can be seen from the incremental backup process that when the NBAP process is running inside the NodeB, there is inter-board communication. There will be a period of time between the receipt of the request message and the return of the response message between the boards, and the hot backup driver module will transfer the backup resources. It takes a while to get to the standby board. Although the multiprocessor system with distributed data storage structure greatly improves the efficiency of hot backup, it may still appear that some NBAP resource configuration has been generated on the BBU, and when the active / standby switchover occurs The SCM standby board still does not have corresponding NBAP resources.

[0101] In order to solve this abnormal situation, when the switchover occurs, the SCM standby board will upgrade to the new SCM mai...

Embodiment 3

[0121] The following mainly describes the processing of the RNC message and the OM configuration message during the NBAP resource recovery process (switching process) and the processing of the ongoing process.

[0122] During the restoration of NBAP resources, since it is necessary to ensure that the NBAP resources of the SCM and multiple BBUs are consistent at this time, it is required that a new NBAP process cannot be performed during the recovery of NBAP resources, otherwise, the NBAP resources stored on the SCM are prone to confusion . For the RNC resource configuration request message and OM resource configuration message received during the resource recovery process, this part of the message is temporarily cached in the SCM, and the processing of this part of the message is performed after the resource recovery process is completed.

[0123] For the NBAP process initiated by the RNC, after the BBU judges that the switchover has occurred, it will send a post-switching res...

Abstract

The invention relates to a backup method and a recovery method of an NBAP resource of an NodeB, wherein the NodeB includes an SCM and a BBU. The backup method comprises following steps: a step 1 in which an SCM mainboard receives a resource configuration request message sent from a RNC, and sends an NodeB inner configuration request message to the BBU effected by current NBAP; a step 2 in which the BBU receives the NodeB inner configuration request message, completes configuration towards a base band unit, and returns a response message for successful configuration to the SCM mainboard; a step 3 in which the SCM mainboard receives the response message of the successful configuration in the BBU, then configures the NBAP resource on the SCM mainboard, sends the resource to be copied to a SCM spare board; a step 4 in which the SCM spare board modifies corresponding resource based on the copied resource. With the method of the invention, reliability of the resource during the NBAP process is ensured.

Description

technical field [0001] The invention relates to a backup and recovery method of NBAP resources of a NodeB, in particular to a fast data backup and recovery method capable of keeping the data stored on the SCM and multiple BBUs consistent in the NodeB. Background technique [0002] The NBAP (NodeB Application Part) protocol belongs to the Iub interface wireless network control plane, and is located in the SCM (System Control Management Unit, System Control Management) in the NodeB (base station) to realize the management of wireless network resources. [0003] Since the NBAP resources on the SCM are very important, and are often located on a piece of hardware (hereinafter collectively referred to as the SCM board), once the hardware is abnormal, it will directly cause the NodeB product to be in an unusable state. Therefore, NodeB products usually adopt a hot backup processing method for these resources, and use the active and standby board structure to back up wireless networ...
