Description

A method for transmitting messages between communication interfaces

technical field

The invention relates to the field of mobile communication, in particular to a method for transmitting messages between various interfaces in a mobile communication system.

Background technique

In the WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) system, when the user is establishing a connection, after the RNC (Radio Network Controller, radio network controller) initiates a request for establishing a wireless link to the NodeB, it will start a or Periodic measurement of multiple NodeBs, each periodic measurement will generate a periodic measurement report. Processing a periodic measurement report requires the cooperation of multiple modules. As shown in Figure 1, the periodic measurement request is sent to the corresponding signaling processing module through the Iub interface processing module. It is sent to the corresponding measurement executive for measurement, sampling and execution; the measurement report is generated by the measurement executive and forwarded to the signaling processing module, and then forwarded to the IUB interface processing module by the signaling processing module. Taking the user's Sir (Signal-to-Interference Ratio, Signal-to-Interference Ratio) measurement as an example, firstly send the execution measurement command to the demodulation unit of NodeB as the measurement execution body, and the demodulation unit performs sampling filtering and other processing and generates a measurement report Then it is forwarded to the Iub interface processing module through the signaling processing module.

In the prior art, the method for the measurement executive to send an interface message to the signaling processing module is as follows: the system first judges whether the measurement report of each user process of the measurement executive has reached the sending cycle, and if it reaches the sending cycle, it immediately sends a message to the signaling processing module. The module sends the measurement report of the arrival sending time one by one. The measurement report is an interface message sent through the interface between the measurement executive and the signaling processing module.

However, there is a problem with the above existing technologies: as shown in Figure 1, each measurement executive may carry multiple users, that is, contain multiple user processes, and the more users it carries, the more periodic measurement reports may be sent at the same time . Assuming that the number of users supported by a certain measurement execution body is N=200, and each user needs to start 2 periodic measurements, and all measurement report periods are 100ms (that is, 10 measurement reports per second), the measurement execution body per second The number of measurement reports to be sent by the bus interface with the signaling processing module is 200*2*10=4000/second. Since the interface between the measurement executive and the signaling processing module may be an interface between different boards or a certain type of bus on the same board, and the processing capacity of the bus interface is certain, therefore, too frequent interface messages will lead to message queue Phenomena such as congestion, message retransmission, and message discarding will lead to system crashes in severe cases.

Detailed ways

The basic principle of the present invention is: multiple messages to be sent at a certain moment are combined into a large message body for sending according to a certain message format, so as to achieve the purpose of reducing interface messages.

To use the present invention, it is first necessary to set the sending message format; then combine the messages of multiple user processes arriving at a measurement execution body at the sending time according to the sending message format; then send the message combined according to the sending message format to the signaling processing module.

In order to enable the signaling processing module to analyze the combined message, before combining each message arriving at the sending time, a certain sending message format must be set. The present invention sets the sending message format as two parts of the message header and the message body. part. The key field of the message header is the number of message reports,

In addition, the message header of the combined message may include a message type field in addition to the message report number as a key field. The message type is used to distinguish different types of messages so that the signaling processing module can perform classified processing and speed up the processing speed of the signaling processing module. After receiving the combined message, the signaling processing module splits the combined message according to the number of valid messages displayed by the number of message reports, and at the same time combined with the message type. Common message types include: public message types, private message types, specific message types, error message types, etc.

In the WCDMA system, during the connection establishment process of the user, after the RNC initiates a request for establishing a wireless link to the NodeB, it will start periodic measurement of one or more NodeBs. In the process of processing a periodic measurement report, the measurement report reported by the measurement execution body to the signaling processing module is a relatively common interface message, and the specific implementation process of the transmission method described in the present invention will be described in detail below as the first embodiment .

Embodiment 1: In this embodiment, a centralized message processing module is defined to complete the message combination function.

The measurement report reported by each user measurement process to the signaling processing module is a periodic report. Multiple user measurement processes share a periodic timer. When the timer expires, the periodic report of the user process at the sending time is sent. The method for judging whether the sending period is reached is the same as that of the prior art, specifically as follows: a timer Tc is started when the system starts, and the timer can be guaranteed to be an integer multiple of all periodic measurement reports, that is, the minimum granularity time of the periodic measurement reports unit; then for each user's periodic measurement process, start a counter Nj, the time increases a cycle Tc every time, the measurement process counter adds 1, and judges whether the product of this counter and Tc is an integer multiple of the current measurement process cycle T, if If yes, it is determined that the user measurement process has reached the sending time.

In this embodiment, when the timer reaches the time, the centralized message processing module judges the user measurement process of each activity, and when it is judged that the measurement process needs to report the measurement report, all the measurement report messages that need to be reported at this time are sent according to the predetermined The sending message format is combined, and after being combined into a large measurement report message combination, it is sent to the signaling processing module. After receiving the large measurement message assembly, the signaling processing module splits all the small measurement report messages from the front to the back one by one from the head of the message body, and immediately sends the split measurement report messages one by one. The number of split measurement reports is indicated by the number of messages field in the header of the combined message body.

FIG. 2 is a schematic structural diagram of the large measurement report message assembly assembled according to the predetermined sending message format. As shown in the figure, the message body of each large measurement report is divided into two parts, that is, a message header part and a message body part. The message header in this embodiment includes two fields: message type and message report number.

The message type is used to distinguish different message types, which is convenient for the signaling processing module to classify and process. Common message types include public message types, dedicated message types, specific message types, and error message types. The number of message reports refers to the number of effective messages starting from the first message after the message header, and the number of messages indicates the number of messages to be split by the signaling processing module.

The message body part contains all valid small message reports, that is, message reports for each user process up to the send time. The information contained in each small message report includes three parts: measurement process identifier PID, small message length, and small message content body. The measurement process identifier PID is used to distinguish each measurement process ID. The length of the small message refers to the length of the content body of each small message that follows it. The content body of the measurement report of different user processes, that is, the content body of each small message can be different. equal length.

Figure 3 is an application example of the above-mentioned large measurement report body. As shown in the figure, a certain measurement executive body has four user measurement processes at a certain moment that need to report measurement reports, that is, the number of measurement reports N=4; the message type is public message Type; the lengths of the four messages, that is, the lengths of the content bodies of the four measurement reports are 4, 5, 6, and 7 bytes in sequence.

The reporting process is as follows: the message centralized processing module first initializes a large memory, and initializes a variable to record the filling position of the next message report. The message centralized processing module cycles all active measurement report processes. If the conditions are met, the measurement process PID of the current measurement report and the length of the measurement report are obtained respectively, and filled to the back of the content body of the previous message report, and the entire memory is copied according to the length of the measurement report. The measurement report message body, after each message report is filled, the filling position of the next message report is recorded and recalculated, and the number of measurement reports in the message header is increased by 1. After traversing all active user measurement processes, multiple preset The large measurement message body of the measurement report sent is sent to the signaling processing module. After the signaling processing module receives the large measurement message assembly, it first takes out the number of valid messages from the message header according to the agreed data format, and then starts from the header of the message body and splits all the small measurement report messages one by one from front to back. And immediately send the split measurement report messages one by one.

In addition, it is also possible to record the type of the copied message report while adding 1 to the number of measurement reports in the message header as described above. After the signaling processing module receives a large measurement message assembly, it The number of effective messages indicated by the number of message reports is sent to different sub-modules for processing according to the message type.

Fig. 4 is a schematic diagram of the processing flow of the measurement report by the message centralized processing module.

First, when the timer time arrives, initialize a large measurement message body and define its length according to the sending message format defined above (step 1);

Next, it is judged whether all active user measurement processes have been traversed (step 2). If traversed, then further judge whether the number of measurement reports in the current large measurement message body is 0, if it is 0, then wait for the next period of the timer (step 4), otherwise, replace the currently filled large measurement message body Send out (step 5); if not traversed yet, proceed to the next step;

Step 6, judging whether the product of the current measurement process counter Nj and Tc has been an integer multiple of the current measurement process period T, that is, Nj×Tc=Tj;

If the formula described in step 6 is satisfied, it is further judged whether the addition of the current measurement report will cause the large measurement message body to exceed the defined maximum length (step 7);

If the defined maximum length is not exceeded, the entire small measurement report message is copied into a large message structure according to the message sending format defined above (step 8);

If the addition of the current measurement report causes the large measurement message body to exceed the maximum length Lmax that the system can support, then first send the large measurement message body (step 9), and re-initialize a large measurement message body (step 10), and add the current measurement report to In the new large measurement message body (step eleven), continue to the next step.

In step 12, add 1 to the current measurement process counter, and continue to traverse active user measurement processes.

The present invention is not only applicable to periodic messages, but also applicable to a certain type of message sent at a certain moment. For example, when a certain cell is deleted and the messages of 100 users corresponding to the cell need to be deleted, the present invention can be used In the transmission method, 100 messages are combined into a large message body and sent to the signaling processing module. The transmission process will be described below as the second embodiment of the present invention.

Embodiment 2: Since deleting a certain cell is a predictable behavior, it is not necessary to set a timer to trigger the occurrence of an event in this case. Therefore, after deleting a cell, if it is considered that the measurement executive needs to send several messages to the signaling processing module continuously, then combine the messages to be sent into a large message body in the following manner:

The message centralized processing module first initializes a large memory, and initializes a variable to record the filling position of the next message report. The message centralized processing module cycles all active measurement report processes, and if it needs to be sent, obtains the measurement process PID of the current measurement report and the length of the measurement report, fills them in the back of the content body of the previous message report, and copies the entire measurement report according to the length of the measurement report The measurement report message body, after each message report is filled, the filling position of the next message report is recorded and recalculated, and the number of measurement reports in the message header is increased by 1. After traversing all active user measurement processes, multiple preset The large measurement message body of the measurement report sent is sent to the signaling processing module. After receiving the large measurement message assembly, the signaling processing module first takes out the number of valid messages from the message header according to the agreed data format, and then splits all the small measurement report messages from the front to the back one by one starting from the message body header , and immediately send the split measurement report messages one by one. Since the messages sent in this embodiment are of the same type, there is no need to record the message type field in the message header.

The processing flow of the message centralized processing module is as follows:

First, according to the sending message format defined above, initialize a large measurement message body and define its length (step 1);

Next, it is judged whether all active user measurement processes have been traversed (step 2). If it has been traversed, then further judge whether the number of measurement reports in the current large measurement message body is 0, if it is 0, end the operation, otherwise, send the currently filled large measurement message body (step 3); if it has not been traversed , then further judge whether adding the current measurement report will cause the large measurement message body to exceed the defined maximum length (step 4);

If the defined maximum length is not exceeded, the entire small measurement report message is copied into a large message structure according to the message sending format defined above (step 5);

If the addition of the current measurement report causes the large measurement message body to exceed the maximum length Lmax that the system can support, then first send the large measurement message body (step 6), and re-initialize a large measurement message body (step 7), and add the current measurement report to In the new large measurement message body (step eight), continue to traverse the active user measurement process (step nine).

The interface information transmission method described in the above two embodiments is not only applicable to the message forwarding of the interface between modules in a single board, but also applicable to the message forwarding of the interface between single boards and between products with interface message interaction. For the message forwarding of the inter-interface, as shown in Figure 2, the measurement executive body can be located in board A, while the signaling processing module can be located in board B, and a large number of messages sent by board A to board B at certain periodic intervals can be first The method for organizing the sending information format described in the present invention is combined into a large message body and then sent. Similarly, the measurement executive and the signaling processing module may also be located between different products.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be It is regarded as the protection scope of the present invention.
