The embodiment of the present invention determines the idle load by determining the idle load capacity of at least one core network node shared between the core network node pools, and according to the load information of the core network node pool sharing the core network node. The capacity is allocated to each core network node pool, so that the core network node pool to which the idle load capacity is allocated has a larger load capacity, effectively solving the problem of processing resource shortage of the overloaded core network node pool. Because the core network node shared by the core network node pool provides idle load capacity, the embodiment of the present invention does not need to reserve a load capacity for each core network node, and multiple core network node pools can share one idle. The core network node loads capacity resources.

The core network node includes network elements of various core networks capable of performing similar functions, such as a mobile switching center, and the core network node pool is a collection including a plurality of such core network nodes.

The main implementation principle, the specific implementation manner, and the corresponding beneficial effects of the technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings, taking the mobile switching center MSC and the mobile switching center pool MSC Pool as examples. The implementation principle, other types of core network nodes can also achieve the same function.

As shown in FIG. 1 , a specific flow chart of a method for allocating idle capacity of a core network node according to an embodiment of the present invention includes the following steps: Step 11: Determine an idle load capacity of at least one core network node MSC that is preset between the core network node pool MSC Pool and the MSC Pool, and the shared MSC may also be referred to as an edge MSC, the MSC Pool and the edge MSC. The positional relationship between the two is shown in Figure 2a, 2b, which may be that two MSC Pools share one edge MSC, or that multiple MSC Pools share one or more edge MSCs;

Step 12: According to the load information of each MSC Pool sharing the edge MSC, allocate the determined idle load capacity to each MSC Pool, where, according to the MSC Pool load information, according to the MSC Pool, which is light to heavy, respectively Corresponding to the capacity factor from small to large, the corresponding capacity factors are respectively configured for each MSC Pool, and then the determined idle load capacity is not repeatedly divided into the load capacity components corresponding to the above capacity factors, and will be divided. The obtained idle load capacity components are respectively allocated to the corresponding MSC Pools.

The executor of the foregoing steps may be the edge MSC, or may be a device for allocating the idle load capacity of the foregoing solution. The device will be described in the following device embodiments, and details are not described herein again.

Preferably, the application environment of the foregoing method provided by the embodiment of the present invention is generally applicable to the MSC Pool overload. Therefore, before determining the idle load capacity of the edge MSC in the foregoing step 11, the method may further include the steps of: determining to share the edge. At least one MSC Pool in the MSC Pool of the MSC is greater than a preset negative value. The following two methods may be used to determine that the MSC Pool sharing the edge MSC is greater than a preset negative Planting threshold:

The first method is: a passively determined manner, that is, according to the received allocated idle load capacity request message, determining that at least one MSC Pool in the MSC Pool sharing the edge MSC is greater than a preset load threshold, where The request message is sent by the MSC Pool that is greater than the preset load threshold when determining that the load is greater than a preset load threshold;

The second method is to actively determine the MSC Pool's load, and according to the preset load threshold and the MSC Pool's load information obtained by monitoring (for example, the MSC Pool can be used to report to the edge MSC periodically). The manner of carrying the information or the manner in which the edge MSC actively acquires the MSC Pool load information to obtain the bearer information of the MSC Pool), and determines that the edge MSC is shared. At least one MSC Pool in the MSC Pool has a load greater than a preset load threshold.

For the above step 12, since the idle bearer capacity of the edge MSC may be too small, even if there is no idle load capacity before the step 12 is performed, in the embodiment of the present invention, the edge MSC may also be used. The load is transferred to other MSCs in the smaller MSC Pool sharing the edge MSC to release the load capacity of the edge MSC, and then step 12 is performed. Specifically, the process includes the following steps:

Step 1 : First, according to the idle load capacity of the edge MSC and the preset idle load capacity threshold, determine whether the idle load capacity of the edge MSC is less than a preset idle load capacity threshold, and when the judgment result is no, perform Step 12, and when the determination result is yes, step 2 is performed;

Step 2: The bearer of the edge MSC is transferred to the other MSC, and after the current idle load capacity of the edge MSC is greater than or equal to the threshold of the idle load capacity, the step 12 is performed, where the other MSCs are shared. In the MSC Pool of the edge MSC, and the MSC Pool in which the other MSCs are located is not greater than a preset load threshold, and the edge MSC may transfer its own load to one of the other MSCs or On multiple MSCs, it is also possible to transfer its own load multiple times to one or more of the other MSCs.

Further, referring to FIG. 3, in order to transfer the load of the edge MSC to other MSCs, FIG. 3 intuitively illustrates the process of transferring the edge MSC.

For the above step 12, the determined idle load capacity may be allocated to the MSC Pool sharing the edge MSC by using the following steps:

First, according to the bearer information of each MSC Pool sharing the edge MSC, corresponding capacity factors are respectively configured for each MSC Pool according to the small to large capacity factor corresponding to the MSC Pools that are light to heavy;

Then, according to the small to large space load capacity components respectively corresponding to the small to large capacity factors, the idle load capacity determined in step 11 is not repeatedly divided into corresponding upper capacity factors. The idle load capacity component, for example, if the total amount of current idle load capacity of the edge MSC determined in step 11 is 1, and the capacity factors allocated for MSC Pool1 and MSC Pool2 sharing the edge MSC are respectively 1 and 3, Corresponding to the capacity of MSC Pooll and MSC Pool2 The child needs to divide the idle load capacity component occupying 1/4 of the idle load capacity from the determined idle load capacity as the idle load capacity component corresponding to the MSC Pool1, and the remaining idle load capacity. The idle load capacity component of 3/4 size is obtained as a divided idle load capacity component corresponding to MSC Pool2;

Finally, the allocated idle load capacity components are respectively allocated to the corresponding MSC Pool, for example, the idle load capacity component of the 1/4 of the idle load capacity obtained by the above division is allocated to the MSC Pooll, and the rest is The idle load capacity component of the 3/4 size of the idle load capacity is allocated to the MSC Pool2.

In particular, if the load of the MSC Pooll is small, and the load of the MSC Pool2 is large, the total idle capacity of the total amount of 1 can also be allocated to the MSC Pool2, corresponding to the MSC Pooll and the MSC Pool2. The capacity factor can be set to 0 and 1, respectively.

The foregoing is a description of the method for allocating the idle load capacity of the core network node provided by the embodiment of the present invention, and the specific implementation manner thereof. According to the foregoing description, the method for allocating the idle load capacity of the core network node provided by the embodiment of the present invention is The following technical effects can be achieved:

1. It is not necessary to make major changes to the existing network, but by assigning the idle load capacity of the edge core network node shared between the core network node pools to the over-loaded core network node pool, The over-carrying core network node pool provides more load capacity, and solves the problem that the over-the-counter core network node pool processing resources existing in the prior art are tight;

2. In the embodiment of the present invention, a certain core network node in the core network node pool with a heavy load is faulty, or the load of the entire core network node pool suddenly increases, causing the core network node pool to process resources. The problem of the tension, even if the edge core network node is heavy at this time, the embodiment of the present invention can also transfer the load of the edge core network node to the same core network node pool as the edge core network node. The other core network nodes are lightly loaded, so that the idle load capacity is effectively obtained for the core network node pool with heavy load, and the pressure of the core network node pool is alleviated, and the load is also realized. Equilibrium distribution on each core network node pool.

Specifically, the following is an example of the application of the method for allocating the idle load capacity of the core network node provided by the embodiment of the present invention, and details the specific method provided by the embodiment of the present invention. Implementation process:

Example 1:

As shown in FIG. 4a, it is a schematic diagram of an application environment of Embodiment 1. In this figure, an edge MSC is shared between MSC Pool1 and MSC Pool2, and the edge MSC can be logically divided into five units in the figure, that is, logical MSC1. The unit, the logical MSC2 unit, the determining MSC1 unit, the determining MSC2 unit, and the allocating MSC unit, the five units cooperate to complete the method for allocating the idle network capacity of the core network node provided by the embodiment of the present invention. Referring to FIG. 4b, the following embodiment is used. The method for allocating the idle network capacity of the core network node is described in the specific application flow in the application environment as shown in FIG. 4a, and the process includes the following steps:

Step 41: Determine the MSC1 unit and the judgment MSC2 unit to monitor the load of the MSC Pool1 and the MSC Pool2 respectively. For example, determine that the MSC1 unit/determination MSC2 unit can obtain the load information of the MSC Pool1/ MSC Pool2 in real time, timed or periodically. The method of monitoring the bearer of the MSC Pooll/MSC Pool2 may also be performed by the MSC1 unit/determining the MSC2 unit receiving the real-time, timing or periodic reporting of the bearer information of the MSC Pooll MSC Pool2, for the MSC Pooll/MSC Pool2 The bearer is monitored, wherein the load information of the MSC Pooll/MSC Pool2 includes the VLR user number information, the traffic information, and the like;

Step 42: When determining the load information of the MSC Pool1 obtained by the MSC1 unit 1 and the preset load threshold, and determining that the current load of the MSC Pool1 is greater than the preset load threshold, reporting the current MSC Pool1 to the allocated MSC unit. Carrying information;

Step 43, the allocation MSC unit sends a pre-answer message to the determining MSC1 unit after receiving the current bearer information of the MSC Pool1 reported by the MSC1 unit;

Step 44: The allocating MSC unit sends a notification message requesting to report the current bearer information of the MSC Pool2 to the determining MSC2 unit.

Step 45: The allocating MSC unit receives the current load information of the MSC Pool2 that is determined by the MSC2 unit according to the notification message.

Step 46: The allocating MSC unit further determines an idle load capacity of the edge MSC, and determines, according to the bearer information of the MSG Pool1 and the MSC Pool2, and the idle load capacity of the edge MSC. The allocation of idle load capacity;

Step 47: The allocating MSC unit allocates the MSC Pool1 and the MSC Pool2 to the MSC Pool1 and the MSC Pool2 respectively according to the determined allocation manner, and notifies the MSCI unit and the judgment unit 1^€2 of the allocation result;

Step 48: Determine that the MSC1 unit and the determining MSC2 unit return a response message to the allocated MSC unit after determining that the idle load capacity is successfully allocated, and the process is terminated.

Specifically, in the foregoing step 46, if the determined idle load capacity of the edge MSC is large (at the same time, it may further be determined that the load of the MSC Pool2 at this time is not greater than a preset load threshold), then the determination is made. The time allocation method may be a method of allocating idle load capacity by changing the edge MSC capacity factor, that is, according to the load information of MSC Pooll and MSC Pool2, according to the light to heavy MSC Pool of the bearer, respectively, corresponding to small to large In the capacity factor mode, the corresponding capacity factor is configured for the MSC Pool. For example, a larger capacity factor is allocated for the relatively heavy MSC Pool1, and a smaller capacity factor is allocated for the relatively light MSC Pool1; then, the idle bear capacity of the edge MSC is not repeatedly divided into corresponding The idle load capacity component of the capacity factor; finally, the divided idle load capacity components are respectively allocated to the corresponding MSC Pool. In the first embodiment, the edge MSCs are respectively assigned to correspond to the allocated MSC Pooll. The logical MSC1 unit of the idle load capacity and the logical MSC2 unit corresponding to the idle load capacity allocated to the MSC Pool2. Therefore, in the foregoing allocation manner, the non-access stratum can be notified by the configured capacity factor in the first embodiment. The node selection function (NNSF, Non Access Stratum Node Selection Function) module, and the capacity factor of the edge MSC is readjusted by the NNSF module, thereby changing the idle load capacity of the logical MSC1 unit and the logical MSC2 unit.

It should be noted that, in the foregoing step 46, when the determined idle bearer capacity of the edge MSC is too small to be allocated to the MSC Pool1 to alleviate the problem of resource shortage of the MSC Pool1 processing, if the MSC Pool2 is idle at this time, If there are many processing resources, it may be considered to transfer part or all of the edge MSC's own load to other MSCs in the MSC Pool2. For example, before performing step 47, if it is determined that the idle load capacity of the edge MSC is not greater than the preset idle negative capacity The threshold value can further obtain the load information of the other MSCs other than the edge MSC in the MSC Pool2; then, the load of the edge MSC is transferred to other MSCs, so that the current idle load capacity of the edge MSC is greater than or equal to the preset. The idle load capacity threshold. In this way, the load can be transferred from one MSC Pool to another, thereby realizing the transfer between the MSC Pool and balancing the load between the MSC Pools.

Example 2:

The embodiment 2 still uses the schematic diagram of FIG. 4a as the application environment, and the specific implementation flowchart of the embodiment 2 is as shown in FIG. 5, and includes the following steps:

Step 51: Determine that the MSC1 unit and the determining MSC2 unit respectively monitor the bearers of the MSC Pool1 and the MSC Pool2, for example, determine that the MSC1 unit/determination MSC2 unit can obtain the bearer information of the MSC Pooll/MSC Pool2 through real-time, timing, or periodicity. Way to monitor the load of MSC Pooll/ MSC Pool2;

In step 52, the MSC1 unit/determination MSC2 unit reports the received bearer information of the MSC Pool1/MSC Pool2 to the allocated MSC unit by means of the timing report or the periodic report. Step 53: The allocated MSC unit receives the judgment MSC1 unit. / After determining the bearer information of the MSC Pool1/MSC Pool2 sent by the MSC2 unit, sending a response message to the determining MSC1 unit/determining MSC2 unit;

Step 54: The allocated MSC unit determines, according to the received bearer information of the MSC Pool1, whether the bearer information of the MSC Pool1 is greater than a preset load threshold, and determines the negative of the MSC Pool2 according to the received bearer information of the MSC Pool2. Whether the planting information is greater than the preset load threshold, and if the judgment is MSC Pooll, the load information at this time is greater than the preset load threshold, then step 55 is performed, and when the judgment result is the load of MSC Pooll and MSC Pool2 When the information is not greater than the preset load threshold, the process may be terminated or the process may be skipped to step 51. In the second embodiment, the allocated MSC unit may also directly determine the allocation capacity request message sent by the MSC Pool 1 to determine. The load of the MSC Pool 1 is greater than the preset load threshold, wherein the request message is sent by the MSC Pooll after determining that the load is greater than the preset load value;

Step 55: The MSC unit is allocated to determine the idle load capacity of the edge MSC, and according to the MSC The bearer information of the pool1 and the MSC Pool2 and the idle bearer capacity of the edge MSC are correspondingly allocated to the MSC Pool1 and the MSC Pool2, and the allocation manner of the step 55 is specifically referred to the edge MSC in Embodiment 1. The allocation of the idle load capacity is not described here. In this step 55, if it is determined that the current idle load capacity of the edge MSC is not greater than the preset idle load capacity threshold, the edge may also be used. The load of the MSC is transferred to the other MSCs, so that the current idle load capacity of the edge MSC is greater than or equal to the preset idle load capacity threshold, and then the current idle load capacity of the edge MSC is allocated to the MSC Pool1 and the MSC Pool2. At the same time, the allocating MSC unit may also notify the determining MSC1 unit and the determining MSC2 unit of the allocation result; Step 56, determining that the MSC1 unit and the determining MSC2 unit return a response message to the allocating MSC unit after determining that the idle load capacity is successfully allocated, and the process ends. .

The above embodiment of the present invention takes the MSC as a representative core network node as an example, and illustrates a method for allocating idle core capacity of the core network node in the case that the core network node constitutes a core network node pool, and accordingly, The embodiment of the invention provides a device for allocating idle capacity of a core network node, and a specific structure diagram thereof is shown in FIG. 6 and includes the following functional units:

Therefore, the core network node provided by the embodiment of the present invention is idle and negative. The dispensing device of the planting capacity may further comprise:

The determining unit 64 is configured to determine, after the allocation unit 62 allocates the idle load capacity of the edge core network node determined by the idle load capacity determining unit 61 to the core network node pool, according to the current bearer information of the core network node pool. Whether the current idle load capacity of the edge core network node pool determined by the load capacity determining unit 61 is less than a preset idle load capacity idle value;

The transferring unit 65 is configured to transfer the load of the edge core network node to the other core network node when the determination result of the determining unit 64 is YES, until the edge core network node determined by the idle load capacity determining unit 61 is currently idle.
