Description

A method for realizing base station power failure alarm

technical field

The invention relates to a method for realizing a power failure alarm, in particular to a reporting method for a base station system power failure alarm.

Background technique

In modern base station management, it is required to implement the function of power failure alarm, so as to distinguish whether the base station is a power failure failure or other line reasons causing communication failure. Generally, the power supply of the base station will give a power-off signal when it is powered off, and maintain the power supply for 100ms to 500ms. The base station must reliably report the power-off warning message to the base station controller during this period.

The existing power failure alarm generally has the following implementation methods:

The first method is to use the internal register bits of the communication chip to realize power failure alarm. When the base station is powered off, the communication between the base station and the base station controller is still intact. By modifying one or more register bits of the physical communication chip on the base station side, the communication chip will transmit these bit information to the opposite chip through the physical link. And save it in its specific register, and then the base station controller software detects these data to realize power failure alarm. Since generally few bits are available, and the transmitted information is completely implemented by physical links, this method is extremely susceptible to interference and has low reliability.

The second method is to realize the power failure alarm by the communication chip. Some communication chips will automatically update some status information when the opposite end sends an abnormality. When the base station is powered off, the communication chip of the base station controller will automatically report the abnormality. The base station controller will realize the power failure alarm by detecting these abnormalities. Because the two situations of power failure and disconnection have basically the same impact on the communication chip, it is generally difficult for the communication chip to distinguish whether it is power failure or disconnection, and its reliability is low.

The third is to realize the power failure alarm by the upper layer protocol. After the base station receives the power-off signal, it notifies the upper-layer protocol, and the upper-layer protocol generates a power-off warning message and then transmits it to the base station controller through the physical link. After the base station receives the power-off signal, it needs to be encapsulated by the upper-layer protocol and then transmitted through the physical link, which makes the reporting delay relatively large. When the maintenance time of the power supply cannot be guaranteed, it often causes the power-off alarm information to be reported too late. The power failure warning information will be lost.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for realizing a base station power failure alarm with fast response speed and high reliability.

In order to solve the above-mentioned technical problems, the basic design concept of the present invention is: after the base station software receives the power-off alarm signal, it reports a pre-defined and specific power-off alarm message rapidly through the existing communication link, and is controlled by the base station. The device recognizes and reports a power failure alarm.

Based on the design idea above, the present invention provides a method for realizing a base station power failure alarm, comprising the following steps:

(a) When the base station is powered off, the power supply module generates a power failure alarm signal. After receiving the power failure alarm signal, the processing module of the base station writes the predefined power failure alarm text into the communication chip, and the communication chip writes the power failure alarm message into the communication chip. Send the alarm message to the base station controller;

(b) The base station controller generates power failure warning information in a specific format after obtaining the power failure warning message, and reports the power failure warning information.

Furthermore, the above method may also have the following characteristics: when the base station sends the power-off warning message, it uses repeated sending for many times until the base station is powered off.

Further, the above-mentioned method may also have the following features: the power-off warning message is defined to have a message length and data different from that of a general communication message.

Further, the above method may also have the following features: the power supply module of the base station notifies the processing module of the base station of the power failure alarm signal by way of interruption.

Further, the above method can also have the following characteristics: the step (b) can be further divided into the following steps:

(b1) The processing module of the base station controller obtains the power-off alarm message from the communication chip on the side of the base station controller;

(b2) Whether the processing module of the base station controller identifies whether the received message is a power-off alarm message, if yes, step (b3) is performed, otherwise, normal communication message processing is carried out, and the end is completed;

(b3) The processing module of the base station controller reports the power failure alarm information to the network management of the base station.

Furthermore, the above method may also have the following features: in step (b3), the processing module of the base station controller regenerates a power failure warning message in a specific format and reports it to the network management of the base station.

The power failure alarm realized by the present invention can use the existing physical link to actively send specific power failure alarm information multiple times, which effectively shortens the design and development cycle, and improves the real-time performance, reliability and anti-interference ability of the system , high response speed. At the same time, the invention has the characteristics of simple interface, flexible message definition, strong expansion function and low cost, and successfully solves the problem of high reliability, high response speed and low cost in the prior art.

Fig. 2 is a flowchart of a method for implementing a power failure alarm according to an embodiment of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

FIG. 1 is a schematic diagram of a base station power failure alarm in this embodiment. The figure shows base station 108, base station controller 111, base station network management 114 and other equipment and related modules. Path 101 is the transmission path of power failure alarm information.

As shown in Figure 2, the flow of the method for implementing a power failure alarm in this embodiment includes the following steps:

Step 110, when the base station 108 is powered off, the base station power supply 110 generates a power failure alarm signal, and notifies the embedded processor 107 through the interrupt 109;

The base station system requires that after the base station is powered off, the power supply of the base station can maintain power supply for hundreds of milliseconds to ensure the transmission of the power failure alarm message.

Step 120, after the embedded processor 107 of the base station 108 receives the interrupt signal, in the interrupt processing program, directly write a predefined power failure alarm message to the communication chip 105 through the communication bus 106;

In order to reduce the burden of receiving and processing of the base station controller as much as possible, the power-off warning message needs to be quickly identified, so the power-off warning message is a specific message different from the general communication message, such as the length plus data, The power failure warning message has a different message length and data from the general communication message to ensure fast and reliable identification by the base station controller.

Step 130, the communication chip 105 of the base station sends the power failure warning message to the communication chip 103 of the base station controller 111 through the communication link 104;

All these tasks are required to be completed within the power supply maintenance time of hundreds of milliseconds. In order to improve reliability, the communication chip can perform multiple repeated transmissions until the base station is powered off.

Step 140, the embedded processor 112 of the base station controller 111 obtains a power-off alarm message from the communication chip 103 through the communication bus 102;

Step 150, the embedded processor 112 first carries out the identification of the power-off warning message, if it is a power-off warning message, execute step 160, otherwise, execute step 170;

Step 160, the embedded processor 112 generates a power failure warning message in a specific format, and reports it to the base station network manager 114 through the communication link 113, and ends;

Since the power-off warning message reported by the base station has a special length and data, the general base station controller needs to regenerate a power-off warning message in a specific format to report to the network management. Of course, the base station controller can also transparently transmit the power failure warning message reported by the base station.

Step 170, perform normal communication packet processing, and end.

It can be seen that by adopting the method of the present invention to realize the power failure alarm, the existing physical link can be used to actively send specific power failure alarm information multiple times, which effectively shortens the design and development cycle, and improves the real-time performance and reliability of the system. High performance and anti-interference ability, high response speed. At the same time, the invention has the characteristics of simple interface, flexible message definition, strong expansion function and low cost, and successfully solves the problem of high reliability, high response speed and low cost in the prior art.

Although the disclosed implementation method related to a power failure alarm has been specifically described above with reference to the embodiments, the embodiments described above are illustrative rather than restrictive, without departing from the spirit and scope of the present invention , all changes and modifications are within the scope of the present invention.
