Description

Processing method of Iur-g interface message

technical field

The invention relates to the field of mobile communication, in particular to a method for processing Iur-g interface messages.

Background technique

In order to increase the switching speed between the Global System for Mobile Communications (GSM) network and the Third Generation Mobile Communication System (3G) network, the 3GPP standard protocol working group proposed to increase the base station controller (BSC) in the GSM network and the wireless network in the 3G network. An interface between controllers (RNCs) is generally referred to as an Iur-g interface. Through the Iur-g interface, the BSC and RNC produced by different manufacturers can interact with each other, so as to realize the fast switching between the GSM network and the 3G network. In practical applications, the messages involved in the interaction between the BSC and the RNC through the Iur-g interface are generally called Iur-g interface messages. Among them, the Iur-g interface messages mainly include two types: public measurement messages and information exchange information.

In the following, the processing method of the Iur-g interface message in the prior art will be described only by taking the information exchange message as an example.

Fig. 1 is a message flowchart for starting information interaction in the prior art, as shown in Fig. 1, the method mainly includes:

In step 101, the RNC sends an information exchange initiation request (Information Exchange Initiation Request) message to the BSC.

In practical applications, the information exchange process can be used by the RNC to obtain the radio resource capacity information of the GSM cells subordinate to the BSC. An information exchange initialization request message only carries the identity of one target GSM cell. If the RNC wants to obtain the radio resource capacity information of multiple GSM cells , it must be sent in the form of multiple information interaction initialization request messages.

In step 102, the BSC returns an Information Exchange Initiation Response (Information Exchange Initiation Response) message to the RNC.

An information exchange initialization response message only carries the radio resource capacity information of a target GSM cell, similar to step 101, if the RNC sends multiple information exchange initialization request messages, the BSC returns to the RNC the same amount of information as the information exchange initialization request message Interactive initialization response message.

Fig. 2 is the message flowchart of stopping information exchange in the prior art, as shown in Fig. 2, RNC sends information exchange termination request (Information Exchange Termination Request) message to BSC, wherein, an information exchange termination request message only carries a target GSM The identity of the neighborhood.

In addition, the public measurement process can be used by the RNC to acquire the radio resource occupancy of the GSM cell subordinate to the BSC, and the public measurement process is similar to the above information exchange process. Specifically, when the public measurement is started, the RNC sends a public measurement request message to the BSC. The public measurement request message carries the identity of the target GSM cell. At the same time, the BSC returns a public measurement response message to the RNC. The public measurement response message carries the target GSM cell ID. Resource occupancy information: when stopping the public measurement, the RNC sends a public measurement stop request message to the BSC, and the public measurement stop request message carries the identity of the target GSM cell.

The difference between the public measurement process and the information interaction process is that a public measurement request message can carry the identifiers of multiple target GSM cells, and can carry the identifiers of a maximum of 129 GSM cells. Similarly, the public measurement response message and the public measurement stop message are similar of.

Fig. 3 is the schematic diagram of the processing method of Iur-g interface message in the prior art, as shown in Fig. 3, RNC comprises an interface board, and interface board is the hardware equipment that processes Iur-g interface message, when RNC and BSC carry out public measurement Or when information is exchanged, the interface board is responsible for receiving and sending all Iur-g interface messages. Figure 3 only illustrates that the RNC has four BSCs, and each BSC has two GSM cells. Receiving and sending of Iur-g interface messages between the BSC and the fourth BSC.

However, in the existing network structure, the subordinates of RNC are required to plan according to at least 32 BSCs, and each BSC subordinates has hundreds of GSM cells. Since each information exchange initialization request message or information exchange stop request message is only It can carry a GSM cell ID. It can be seen that in the existing information exchange process, the interface board may be responsible for receiving and sending a large number of information exchange messages at the same time; in addition, although each public measurement request message or public measurement stop request message can maximum Carry 129 GSM cell identities, however, the GSM cells carried in a public measurement message must belong to the same BSC and have the same measurement characteristics, for example, the GSM cells carried in a public measurement message belong to the periodic report measurement characteristics, The GSM cells carried in another public measurement message are event-reported measurement features. It can be seen that in the existing public measurement process, the interface board may also be responsible for receiving and sending a large number of public measurement messages at the same time.

To sum up, the interface board may be responsible for receiving and sending a large number of Iur-g interface messages at the same time. This situation is particularly prominent when the Iur-g interface is turned on or off. Therefore, the instantaneous Iur-g interface message may exceed the RNC interface board. Congestion due to load.

If the total number of interface boards N _bsc cannot be divisible by the total number of _BSCs under the RNC N card, then L _max1* N _card -N _bsc interface boards among the N _card interface boards correspond to L _max1 -1 BSCs, and the remaining interfaces Plates are corresponding to L _max1 BSC.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

Fig. 4 is a flow chart of a method for processing an Iur-g interface message provided by the present invention. As shown in Figure 4, the method includes the following steps:

Step 401, pre-setting multiple interface boards in the RNC, respectively establishing a corresponding relationship between each interface board and a BSC subordinate to the RNC, wherein one interface board corresponds to multiple BSCs, and the BSCs corresponding to different interface boards are different from each other.

Assign BSCs to each interface board according to the scheduling strategy, and establish paths for all BSCs assigned to a certain interface board to process Iur-g interface messages of all GSM cells under the BSC, which is equivalent to the total Iur-g interface The message is processed by air division, and the total load is distributed to each interface board, thereby reducing the load capacity of the interface board. In practical applications, due to the limitation of manufacturing costs, the number of multiple interface boards set in the RNC is generally much smaller than the number of BSCs, that is to say, when establishing the correspondence between each interface board and BSC, one interface board Usually corresponds to multiple BSCs.

The method for establishing the corresponding relationship between each interface board and the BSC is relatively flexible, and the following only uses two methods for establishing the corresponding relationship as examples for illustration.

其中，表示向上取整运算。若接口板总量N_card可被RNC下属BSC的总量N_bsc整除，则每个接口板与L_max1个BSC对应，若接口板总量N_card不能被RNC下属BSC的总量N_card整除，则N_card个接口板中L_max1*N_card-N_bsc个接口板均对应L_max1-1个BSC，而剩余的接口板均对应L_max1个BSC。The total number N _bsc of BSCs subordinate to the RNC can be evenly distributed to each interface board. When the total number of interface boards is N _card , the maximum number of BSCs corresponding to each interface board

in, Indicates a round-up operation. If the total number of interface boards N _card is divisible by the total number of N _bsc of BSCs subordinate to the RNC, each interface _board corresponds to L _{max1 BSCs} . Then L _max1* N _card -N _bsc interface boards among the N _card interface boards correspond to L _max1 -1 BSCs, and the remaining interface boards correspond to L _max1 BSCs.

However, since the total amount of Iur-g interface messages processed by an RNC is determined by the total amount of all GSM cells subordinate to all BSCs subordinate to it, the optimal principle to reduce the load on the interface board is to allocate all GSM cells subordinate to all BSCs subordinate to the RNC The total amount of cells is evenly distributed to each interface board.

其中，

表示向上取整运算。当建立每个接口板与BSC的对应关系时，使得不同接口板对应的所有BSC的下属所有GSM小区的总量相同，但是，由于每个BSC下属GSM小区的总量可能存在差异，因此，即使N_card可被N_cell整除，不同接口板对应的所有BSC的下属所有GSM小区的总量也不一定完全一致。在实际应用中，只是尽量使得不同接口板对应的所有BSC的下属所有GSM小区的总量基本一致。Based on the above principles, if the total number of all GSM cells subordinate to all BSCs subordinate to the RNC is N _cells , the maximum number of GSM cells corresponding to each interface board

in,

Indicates a round-up operation. When establishing the corresponding relationship between each interface board and BSC, the total amount of all GSM cells subordinate to all BSCs corresponding to different interface boards is the same. However, since the total amount of GSM cells subordinate to each BSC may be different, even if N _card can be divisible by N _cell , and the total amount of all GSM cells under all BSCs corresponding to different interface boards may not be exactly the same. In practical application, it is just as far as possible to make the total amount of all GSM cells under all BSCs corresponding to different interface boards basically the same.

In practical applications, one of the methods to try to make the total amount of all GSM cells under all BSCs corresponding to different interface boards basically the same is as follows: first, arrange all BSCs in ascending order of the total number of cells under them, among which the cells The BSC with the largest total amount is regarded as the tail of the team, and the BSC with the smallest total amount of cells is regarded as the head of the team; secondly, starting from the BSC at the tail of the team, each BSC at the tail of the team is sequentially accumulated from the BSC at the head of the team. When the sum of the cells of the BSCs is just less than L _max2 , these BSCs are allocated to one interface board. Then continue to allocate the BSCs that are not allocated at the tail side of the team and the head side of the team according to the above principle (if the number of remaining interface boards is equal to the number of remaining BSCs, the remaining BSCs are directly allocated to the remaining interface boards).

The above method of making the total amount of all GSM cells of all BSCs corresponding to different interface boards basically the same as possible is just an example, and in practical application, it is not limited to the enumerated method.

因此，建立第一接口板与第一BSC和第四BSC的对应关系，建立第二接口板与第二BSC与第三BSC的对应关系，使得第一接口板对应的所有BSC的下属所有GSM小区的总量为4，第二接口板对应的所有BSC的下属所有GSM小区的总量为5，二者基本相同。In order to clearly illustrate the establishment methods of the above two corresponding relationships, the following is illustrated in conjunction with Fig. 5. Fig. 5 is a schematic diagram of a processing method of an Iur-g interface message provided by the present invention, and Fig. 5 is only set in the RNC Two interface boards (N _card =2), and the RNC has four BSCs (N _bsc =4) as an example. According to the establishment method of the above-mentioned first correspondence relationship, each interface board corresponds to two BSCs, or according to the establishment method of the above-mentioned second correspondence relationship, assuming that the total number of all GSM cells subordinate to the first BSC is 1, and the second The total number of all GSM cells under the BSC is 3, the total number of all GSM cells under the third BSC is 2, and the total number of all GSM cells under the fourth BSC is 3, then the total number of all GSM cells under all BSCs under the RNC N _cells = 9,

Therefore, the corresponding relationship between the first interface board and the first BSC and the fourth BSC is established, and the corresponding relationship between the second interface board and the second BSC and the third BSC is established, so that all GSM cells subordinate to all BSCs corresponding to the first interface board The total amount is 4, and the total amount of all GSM cells subordinate to all BSCs corresponding to the second interface board is 5, which are basically the same.

Step 402, determine the number of batches when each BSC processes the Iur-g interface messages in batches.

The Iur-g interface messages of each BSC subordinate cell are sent in batches by using timers and other methods, which is equivalent to performing time-division processing on the Iur-g interface messages sent to each interface board by space division. The Iur-g interface messages to each interface board are shared among the batches of the BSC, thereby further reducing the load on the interface board.

Specifically, methods for determining the batch size include:

First, calculate the maximum number of messages processed by each BSC in the BSCs corresponding to each interface board.

其中，

为向下取整运算，i为大于等于1且小于等于N_card的正整数。If the maximum number of messages that can be processed by each interface board is M _quen , assuming that the number of BSCs corresponding to the i-th interface board is L _i , the maximum number of messages processed by each BSC among the L _i BSCs

in,

For the rounding down operation, i is a positive integer greater than or equal to 1 and less than or equal to N _card .

Second, calculate the total amount of Iur-g interface messages processed by each BSC in the BSCs corresponding to each interface board.

其中，为向上取整运算，第j个BSC的Iur-g接口消息的处理总量

Assume that among the L _i BSCs corresponding to the i-th interface board, the total number of subordinate GSM cells of the j-th BSC is M _{i, j} , where j is a positive integer greater than or equal to 1 and less than or equal to L _i , and there are M _{i, j} GSM cells belong to Q feature sets, and the number of GSM cells included in each feature set is M _{i, j_1} , M _{i, j_2} ... M _{i, j_Q} , and the total number of GSM cells included in this Q feature set is M _{i, j} , then the information exchange message processed by the jth BSC is M _{i, j} , and the public measurement message processed by the jth BSC is

in, For rounding up operations, the total amount of messages processed on the Iur-g interface of the jth BSC

It should be noted that in practical applications, once the network structure is determined, the number L _i of BSCs corresponding to the i-th interface board, the total number of subordinate GSM cells M _i,j of the j-th BSC, and the number of GSM cells contained in Q feature sets The numbers of cells M _{i, j_1} , M _{i, j_2} ... M _{i, j_Q} are all known.

Thirdly, calculate the number of batches when each BSC processes Iur-g interface messages in batches according to the maximum number of messages processed by each BSC in the BSCs corresponding to each interface board and the total amount of Iur-g interface messages processed.

第i接口板分批次处理Iur-g接口消息时的批次数量其中，MAX为取最大值运算，为向上取整运算。Among L _i BSCs corresponding to the i-th interface board, the number of batches when the j-th BSC processes Iur-g interface messages in batches

The number of batches when the i-th interface board processes Iur-g interface messages in batches Among them, MAX is the maximum value operation, is an upward rounding operation.

It should be noted that for each BSC corresponding to the current interface board, the total amount M _{total_i, j} of the Iur-g interface messages processed by each BSC is not exactly the same, and each BSC when processing messages, is It is carried out according to the maximum number of message processing M _{batch_i} , which means that some BSCs need more batches when processing Iur-g interface messages, and some BSCs need more batches when processing Iur-g interface messages However, for the current interface board, the number of batches when processing Iur-g interface messages is equal to the maximum number of batches in the corresponding BSC.

This step is illustrated with reference to FIG. 5 . Assuming that each interface board can handle the maximum number of messages M _quen =201, and the number of BSCs corresponding to the first interface board is L ₁ =2, then the maximum number of messages processed by the first BSC and the second BSC M _{batch_1} =[M _quen /L ₁ ]=100, similarly, the maximum message processing quantity M _{batch_2} =[M _quen /L ₂ ]=100 of the third BSC and the fourth BSC.

Assume that the total amount of Iur-g interface messages processed by the first BSC M _{total_1,1} =100, the total amount of Iur-g interface messages processed by the second BSC M _{total_1,2} =300, and the Iur-g interface messages of the third BSC The total amount of processing M _{total_2,3} =200, the total amount of processing M _{total_2,4} =300 of the Iur-g interface message of the fourth BSC, then the number of batches T _1,1 of the first BSC=[M _{total_1,1} / M _{batch_1} ]=1, the batch quantity T _1,2 of the second BSC=[M _{total_1,2} /M _{batch_1} ]=3, the batch quantity T _2,3 of the third BSC=[M _{total_2,3} /M _{batch_2} ]=2, the batch quantity T _2,3 of the fourth BSC=[M _{total_2,4} /M _{batch_2} ]=3, for these two interface boards, the batch quantity S ₁ of the first interface board=MAX( 1, 3)=3, and the batch quantity S ₂ of the second interface board =MAX(3,2)=3.

When the first BSC processes Iur-g interface messages, the number of batches required is 1, and when the fourth BSC processes Iur-g interface messages, the number of batches required is 3. The number of times is 3; the number of batches required when the second BSC processes Iur-g interface messages is 2, and the number of batches required when the third BSC processes Iur-g interface messages is 3, then the second interface board processes Iur-g The batch size for interface messages is 3.

In addition, it should be noted that the Iur-g interface messages processed by the first interface board and the second interface board are different, and the Iur-g interface messages processed by the first BSC, the second BSC, the third BSC, and the fourth BSC are also different. Different from each other, the batch messages with the same name shown in Figure 5 are only used to illustrate that each BSC performs parallel processing of Iur-g interface messages in the same time period, and it does not indicate that the batch messages with the same name contain the same content.

Step 403, determine the time interval between adjacent batches when each BSC processes the Iur-g interface messages in batches.

Set the interval T _interval between adjacent batches to ensure that when the next batch of messages arrives, the previous batch of messages has been processed.

Step 404, each BSC processes the Iur-g interface messages in batches according to the determined batch quantity and the interval time between adjacent batches.

So far, this process ends.

According to the technical scheme provided by the present invention, a plurality of interface boards are preset in the RNC, the corresponding relationship between each interface board and the BSC subordinate to the RNC is established respectively, and the Iur-g interface message is distributed to each interface board, and the total Iur -g interface messages have been space-divided, and then determine the number of batches and the interval between adjacent batches when each BSC in the BSC corresponding to each interface board processes Iur-g interface messages in batches, according to the determined The number of batches and the interval between adjacent batches, each BSC processes the Iur-g interface messages in batches, and performs time-division processing on the Iur-g interface messages that are space-divided to each interface board, and each interface board The Iur-g interface messages are shared among the batches of the BSC, thereby reducing the load of each interface board and avoiding the congestion of instantaneous Iur-g interface messages.
