The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

Method for collecting system information in mobile communication network

FIG. 1 is a schematic diagram of a method for collecting system information in a mobile communication network according to the present invention, where 1 represents an application server, 2 represents a control point, and 3 represents a controlled point. As shown in Figure 1, due to the large number of network element boards in the network system and the large amount of information, simply relying on a control point to obtain the version and configuration information of the entire system will result in low collection efficiency and easily form a "bottleneck in system performance" ". Therefore, the present invention divides the network system into several hierarchical levels for hierarchical control. And at each level, there are control points 2, and control points 2 manage the control points 3 at this level, and control processes are set on control points 2. The control processes have the following functions:

1) storing the information of the controlled node;

2) receiving and processing the query from the superior node to the present node, and returning the corresponding version configuration information;

3) forward the query message to the lower node;

4) Receive and forward the response message from the lower node.

Currently, the version configuration information in mobile communication systems is divided into three categories:

1) Version information stored throughout the network: mainly including the version stored at each control point;

2) The version information of the entire network board is mainly the version information of the current actual running of each network element board, including software and hardware parts;

3) Board-wide configuration information of the entire network, which mainly includes information for specifying the running version of the board. The information collection method of the present invention can be accurate to the software and hardware version information and system configuration information of the system equipment of each single board.

A method for collecting system information in a mobile communication network that implements the above principles of the present invention will be described in detail with reference to the accompanying drawings. FIG. 2 is a flowchart of a method for collecting system information in a mobile communication network according to an embodiment of the present invention.

As shown in FIG. 2, in step 201, the mobile communication network is hierarchically divided. In this embodiment, the mobile communication network refers to a CDMA 3G mobile communication system, which includes a base station control center and a base station, both of which are composed of a number of subsystems, and a number of single boards are connected under the subsystem. Control board. In this embodiment, the mobile communication system is divided into three layers, and the base station control center It is on the first layer, the base station is on the second layer, and the subsystems under the base station are on the third layer.

In step 202, a control point is set for each layer of the divided mobile communication network. As shown in FIG. 1, in this embodiment, the first-level control point 101 is set at the base station control center, the second-level control points 102, 103, and 104 are respectively set at the main control module of the base station, and the third-level control point 105 is set at the base station. At the main control module of each subsystem below. The control points on each layer manage other control points in this layer and store the information of these control points.

In step 203, a method for starting a system information collection task is determined. In this embodiment, a task startup mode may be selected before system information collection. This embodiment provides two task starting modes: a task customization mode and an active initiation mode. If the active initiation mode is selected, that is, the determination result of step 203 is "No", the process proceeds to step 204, and if the task customization mode is selected, that is, the determination result of step 203 is "yes", the process proceeds to step 206.

In step 204, a user actively initiates a system information collection task and presets a query rule. The user constructs and sends out a network-wide collection task start command message through the client, which indicates the start of the collection task, and the message can be sent to, for example, an application server for processing. The process proceeds to step 208.

In step 205, the system information collection task is customized and a query rule is preset. The user browses and sets network-wide information collection task information through the client, including: the type of system information to be collected; and the time when the task is started, which can be selected in three ways: immediate start, one-time scheduled start, and periodic scheduled start (where the cycle Can be week, day, etc.). Users can customize the collection tasks according to actual needs.

In step 206, the status of the customized task is continuously monitored.

In step 207, it is determined whether it is the start time of the customized task. If the start time is up, a network-wide collection task start command message is automatically generated and sent, which indicates that the collection task starts. This message can be sent to, for example, an application server for processing. The process proceeds to step 208. Otherwise, the process returns to step 206 and continues to monitor the task status.

In step 208, topology configuration information of the mobile communication network is obtained. This can be obtained by querying the records stored in the database by the application server.

In step 209, a network-wide information query message is constructed. This can be achieved by the application server. Its According to the topology configuration information of the entire network and according to preset query rules, all detailed and specific system information query instruction messages to be sent to the mobile communication network are constructed.

In step 210, a system information query instruction message is sent. This can be performed by the application server. It sends the constructed system information query message through the data communication link to the first-level control point of the mobile communication network, that is, the first-level 101 at the base station control center.

In step 211, the mobile communication network collects system-wide system information. Now, the specific process of collecting network-wide system information by the mobile communication network will be described with reference to FIG. 3. FIG. 3 is a further flowchart of the steps of passing system control points and querying system information in a method for collecting system information in a mobile communication network according to an embodiment of the present invention.

As shown in FIG. 3, in step 301, each control point receives a message. In this embodiment, the primary control point 101 can receive both the signaling message from the application server and the response message from the secondary control point. The secondary control points 102, 103, and 104 can also receive the primary control point. The signaling message forwarded by 101 may also receive a response message from the third-level control point 105, and the third-level control point may receive the signaling message forwarded from the second-level control point 102.

In step 302, each control point judges the received message. That is, it is determined whether the received message is a system information query message. If yes, the process proceeds to step 303, and if not, the process proceeds to step 306.

In step 303, each control point further judges whether the received system information query message is an information query message of this layer. If it is, the process proceeds to step 304, and if not, the process proceeds to step 305.

In step 304, the system information query message received by each control point is an information query message of this layer, and then each control point reports the system information of this layer to the application server. In this embodiment, system information of this layer is stored in each control point, so it can be directly reported to the application server without re-querying.

In step 305, each control point forwards the received system information query message to a lower-level control point.

In step 306, each control point judges whether the received message is a response message from a lower layer, and if so, the process proceeds to step 307. If so, the process proceeds to step 307.

In step 307, each control point forwards the received response message from the lower control point to the upper layer.

It should be noted that when the version information of the network system is changed due to the insertion or removal of a board or the addition of a board in each layer, an active reporting method is adopted. If the main control point changes, the main control point actively reports the information of this layer to the application server. If the changed control point is the controlled point, the controlled point actively reports its information to the control point of this layer. The control point decides whether to report.

In step 212, the information collection result is received and stored. This can be achieved by the application server. It receives the version configuration information of this layer returned by the control points at all levels in the mobile communication network, and stores it in the database for use in system maintenance and upgrade of the network.

The reporting module 404 calls the storage module 401, and stores the version configuration information of this layer stored therein. The forwarding module 405 forwards the received system information query message from the upper layer to the lower control point, and forwards the received response message from the lower layer to the upper control point.

It should be noted that the controller 400 is located at a control point of each layer of the mobile communication network divided by the hierarchy.

It should also be noted that when the board at this layer changes, the controller 400 compares the changed version configuration information with the version configuration information stored in the storage module 401. If there is a change, it actively reports it to the application server. . System information collection system in mobile communication network
