Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figure 2, in the present invention, when the communication between the network element 101 and the management and maintenance network 200 is interrupted, the communication capability provided by the communication network 100 where the network element 101 is located is used to establish the management and maintenance terminal 201 and The communication between the network elements 101 obtains the operation information of the network elements 101, so as to realize the remote management and maintenance of the network elements 101.

As shown in FIG. 3 , a remote management system 300 is built in the network element 101 . The remote management system 300 may be a software system running in the network element 101 or a hardware unit integrated in the network element 101 . The remote management system 300 includes a remote access module 301 and a modem module 302, wherein:

The remote access module 301 is used to simulate the call signaling processing behavior of a phone within the jurisdiction of the network element 101, such as a mobile phone or a fixed phone, and establish a connection between the remote management system 300 and the management and maintenance terminal 201 by simulating the call processing behavior of the phone. The service flow channel between them is used to transmit the remote management operation instruction of the management and maintenance terminal 201 to the network element 101. The remote access module 301 has an access identification number, such as a telephone number, IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity), TMSI (Temporary Mobile Subscriber Identity, temporary Mobile Subscriber Identity) or IP (Internet Protocol, Internet Protocol ) address, etc.;

The function of the modulation and demodulation module 302 is to perform modulation, demodulation or encoding and decoding on the management operation instruction information transmitted in the service flow channel, and then transmit it to the operation management module 1011, triggering the network element 101 to perform related operations according to the operation and maintenance command.

Fig. 4 is an implementation flow chart of the remote management method provided by the present invention, which is described in detail as follows:

In step S401, the management and maintenance terminal 201 establishes a communication route with the network element 101 through the communication capability of the communication network to which the network element 101 belongs. The specific method is to set an access identification code in the network element 101 to manage and maintain The terminal 201 initiates a call to the access identification code through the communication network, the network element 101 responds to the call, and performs connection processing on the call, or the management and maintenance terminal 201 sends a short message to the access identification code through a short message, and the network element After receiving the short message, 101 returns a message response, thereby establishing a communication route with the management and maintenance terminal 201;

In step S402, the management and maintenance terminal 201 sends a management operation instruction to the network element 101 through the established communication route;

In step S403, receiving the management operation instruction, demodulating or decoding the management operation instruction, and triggering the network element 101 to execute the management operation instruction;

In step S404, the execution result of the management operation instruction by the network element 101 is received, the execution result is modulated or coded, and then returned to the management and maintenance terminal 201 .

The implementation process of the present invention will be described below by taking the remote management and maintenance of the BSC (Base Station Controller, base station controller) as the network element 101 as an example.

As shown in Figure 4, BSC401 is connected to MSC (Mobile-service Switching Centre, mobile service switching center) 402, and management maintenance terminal 201 is connected to the telephone line in the public switched telephone network 404 by modem 403, also can manage maintenance terminal 201 is connected to the mobile phone, and the mobile phone is used as the modem 403 at the same time, so that the management and maintenance terminal 201 is connected to the mobile communication network, and the management and maintenance terminal 201 uses the access identification number of the communication module access 301 as the called number to BSC401 The remote management system 300 in the call initiates a call, and the telephone call connection signaling, in this example, the paging with the callee's IMSI as the target, will be delivered to the BSC401.

After receiving the above telephone call connection signaling or paging, the call processing module 4011 of the BSC 401 recognizes that the called party is the remote management system 300 built in the network element 101 according to the IMSI of the called party carried in the paging, and then sends the call to the The call connection signaling is forwarded to the remote management system 300;

The remote access module 301 of the remote management system 300 simulates the call signaling processing behavior of the mobile phone by the BSC401 to answer the call, thereby establishing a service flow channel between the remote management system 300 and the management and maintenance terminal 201;

The management and maintenance terminal 201 sends an operation and maintenance instruction to the remote management system 300 of the network element 101 on this service flow channel, and the modem module 302 of the remote management system 300 demodulates/decodes the operation instruction, sends it to the operation management module 1011, and triggers the network element 101 to perform related operations, such as collecting some of its own operating status information, etc.;

After the execution of the network element 101 is completed, the operation management module 1011 forwards the execution result to the modem module 302, and the modem module 302 modulates/codes the execution result information and transmits it to the management and maintenance terminal 201 through the service flow channel.

Similarly, the built-in remote management system 300 of the network element 101 can also actively dial the access identification code of the management and maintenance terminal 201 , and transmit the operation information of the network element 101 to the management and maintenance terminal 201 after establishing a call connection.

For switches and base station controllers that support the short message function, the built-in remote management system 300 can also communicate with the management and maintenance terminal 201 by sending short messages, without the need to establish a service flow channel, and transmit management operation instructions and Running information of the network element 101.
