It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In this embodiment, a method for binding a base station to a virtual machine is provided. FIG. 1 is a flowchart of a method for binding a base station and a virtual machine according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:

Step 102: Sort all the location areas according to the total carrier frequency of all base stations in the coverage of each location area, and add the location information of the location area to the location area information list; according to each coverage area of each location area The number of carrier frequencies owned by the base station sorts all base stations, and adds the ordering information of the base station to the base station information list;

Step 104: Establish a mapping relationship between the location area information list and the base station information list, and query, according to the established mapping relationship, the sorting information of all the base stations in the coverage of all the location areas;

It should be noted that, in the embodiment of the present invention, the mapping relationship may include establishing base station information included in each location area; and by using the mapping relationship, querying, by using the location area information, all sorted base station information lists belonging to the location area; The base station information queries the location area information list to the location area information to which the base station belongs. Based on the mapping relationship, when the binding between the base station and the virtual machine in a location area is processed, the sorted base station information list may be queried according to the location area information, and the base station information list has been sorted according to the number of carrier frequencies. The base station is bound to the most idle virtual machine in turn; or the idle virtual machine can be sorted based on the mapping relationship to obtain the most idle virtual machine; if one virtual machine is not enough, the total number of carrier frequencies of all bound base stations When the virtual machine can process the upper limit of the carrier frequency, it is bound to the secondary idle virtual machine.

Step 106: Bind the base station to the virtual machine in sequence according to the sorting information that is queried according to the mapping relationship.

Through the above steps 102 to 106 of the embodiment, all the location areas are sorted according to the total carrier frequency of all base stations in the coverage of each location area, and according to each base station in the coverage of each location area. The number of carrier frequencies is sorted for all base stations, that is, the location areas covering the plurality of base stations and the base stations are respectively sorted, and the sorting information is added to the location area information list and the base station information list, thereby establishing a relationship between the two. Mapping the relationship, and the ranking information of each base station in the coverage of the location area can be found through the location area information list, that is, the ranking information can be obtained by using the location area and the carrier frequency of the base station, and then the base station is sequentially performed according to the ranking information. Binding with the virtual machine, so that the number of carrier frequencies of the base station is bound to the virtual machine, and the binding between the virtual machine and the telecommunication network service processing is realized.

The method for sorting all the location areas according to the total number of carrier frequencies of all base stations in the coverage of each location area involved in step 102 in this embodiment may include: according to the total load of all base stations in the coverage of each location area. The number of frequencies, sorting all location areas in order of increasing order;

And, in step 102, the manner in which all the base stations are sorted according to the number of carrier frequencies owned by each base station in the coverage of each location area may include: the number of carrier frequencies owned by each base station in the coverage of each location area. All base stations are sorted in order of increasing order.

According to the above sorting manner, the ordering of the location areas may include sorting according to the total number of carrier frequencies in the coverage of the location area, and each base station in the same location area may also be in the same location according to the number of carrier frequencies of the base station. In the optional implementation manner of this embodiment, the above two sortings are all sorted according to the principle of the number of carrier frequencies, and the above manner is only used for illustration, and The configuration is limited, and in other embodiments of the embodiment, the ordering may be performed according to the principle of being small to many.

For the manner in which the base station and the virtual machine are bound in sequence according to the sorting information in step 106 in this embodiment, in an optional implementation manner of this embodiment, the method may be implemented as follows:

Step 106-1: Acquire idle values of two or more virtual machines;

The idle value is the ratio of the number of carrier frequencies being processed by the virtual machine to the upper limit of the number of carriers processed by the virtual machine;

Step 106-2: Binding each of the base stations sorted according to the number of carriers according to the number of carriers in the sorting information that is queried according to the mapping relationship to the virtual machines sorted according to the idle value from small to large;

It should be noted that the binding process may include the following process: It is assumed that the sorted location area information list includes a location area A, a location area B, and a location area C. According to the location area information of the location area A, the three base stations including the base station A-01, the base station A-2, and the base station A-03 are queried from the mapping relationship to the sorted base station information list, and each of them includes 35 carrier frequencies. 30, 15 carrier frequencies; querying from the mapping relationship according to the location area information of the location area B, the sorted base station information list includes three base stations: base station B-01, base station B-02, and base station B-03, which The number of carrier frequencies included is 25, 20, and 10 carrier frequencies respectively; according to the location area information of the location area C, the information is searched from the mapping relationship to the sorted The base station information list includes three base stations: base station C-01, base station C-02, and base station C-03, and the number of carrier frequencies included is 20, 15, and 10 carrier frequencies, respectively. According to the carrier frequency of all unbound base stations, it is necessary to apply for virtual machine A, virtual machine B, and virtual machine C in advance; the maximum number of carrier frequencies that the virtual machine can process is 70. First, the location area A is selected from the location area information list, and the base station A-01 and the base station A-02 are bound to the virtual machine A in turn. At this time, all the base stations bound by the virtual machine A contain 70 carrier frequencies, and cannot be bound again. Base station A-03, because the maximum number of carriers that the virtual machine can handle is 70. The virtual machine B that is idle is selected, and the base station A-03 is bound to the virtual machine B. After the location area A is processed, the idle virtual machine A, the virtual machine B, and the virtual machine C are reordered, and the result of the sorting is virtual machine C, virtual machine B, and virtual machine A. Next, the unprocessed location area B is selected, and the base station B-01, the base station B-02, and the base station B-03 are bound to the most idle virtual machine C. After the processing of the location area B is completed, the idle virtual machines are reordered, and the result of the sorting is virtual machine B, virtual machine C, and virtual machine A. Finally, the unprocessed location area C is selected, and the base station C-01, the base station C-02, and the base station C-03 are bound to the most idle virtual machine B. This facilitates the centralized binding of base stations under one location area to one or more virtual machines, which improves the overall performance of the system.

For the above steps 106-1 and 106-2, it should be noted that the ordering in the obtained ordering information involved in the foregoing embodiment is sorted according to the number of carrier frequencies of the base station, and in the embodiment, In the selected embodiment, the sorting is performed according to the number of carrier frequencies, and the plurality of virtual machines and sorting information sorted according to the idle value are sorted according to the number of carrier frequencies. Each base station is bound to know that the virtual machine with a small idle value is bound to the former base station in the sorting information, that is, the relatively idle virtual machine is bound to the base station with a large number of carrier frequencies, so that The ability to make full use of resources and make efficient use of virtual machines.

In another optional implementation manner of this embodiment, after the step 102 is sequentially bound to the virtual machine according to the sorting information that is queried according to the mapping relationship, the method in this embodiment may further include:

Step 108-1: When all virtual machines are bound to the base station, and one or more base stations are not bound, the corresponding virtual machine is applied according to the unbound base station;

Step 108-2: Bind the unbound base station to the applied virtual machine.

It can be seen from step 108-1 and step 108-2 that, after one or more base stations are not bound after the currently applied virtual machine has been bound, the application needs to correspond to the number of unbound base stations. a virtual machine, and in turn performing a binding operation, the binding operation is performed and the above steps 102 to S106 are performed. The approach adopted is the same. In this way, the binding manner between the base station and the virtual machine is more flexible.

In another optional implementation manner of this embodiment, after the base station is bound to the virtual machine in sequence according to the sorting information that is queried according to the mapping relationship, the method in this embodiment may further include: when deleting the base station. The debinding relationship between the deleted base station and the virtual machine is removed. That is, when the base station is deleted, the binding relationship between the deleted base station and the virtual machine is released, which is advantageous for saving resources.

In another optional implementation manner of this embodiment, after the base station is bound to the virtual machine in sequence according to the sorting information that is queried according to the mapping relationship, the method in this embodiment may further include: When the traffic of the bound base station is lower than the preset traffic threshold, the base station that is lower than the preset traffic threshold is migrated and bound to other virtual machines. That is to say, when the base station has no service to be executed, the base station can be migrated to other virtual machines, which can avoid unnecessary waste and save the virtual machine overhead. The virtual machine of the embodiment of the present invention may include: a virtual machine with a traffic higher than a preset traffic threshold, and the virtual machine after the migration is completed, releasing the occupied hardware resources, and realizing the use of hardware resources. optimization. In the embodiment of the present invention, the threshold below the preset traffic volume includes no service.

It should be noted that the traffic threshold may be calculated according to a calculation formula, and the reference factor may include: the number of channels for the CS voice service application, the number of measurement reports of the CS language service, the number of channels for the PS data service application, and the CPU processing of the virtual machine. ability. The traffic value is a value within one measurement period. The formulas that can be referred to are: Caps=10000* (CSAccWeight*CS request number/100+PSAccWeight*PS request number/100+CSTrafficWeight*CS traffic volume/100)/time length (10ms);

(1) The number of CS requests is the number of wireless channel requests when the CS voice service is accessed, and CSAccWeight is the weight value related to the number of CS requests;

(2) The number of PS requests is the number of radio channel requests when the PS data service is accessed, and the PSAccWeight is the weight value associated with the number of PS requests;

(3) CS traffic is the number of CS traffic measurement reports, and CSTrafficWeight is the weight value associated with CS traffic;

(4) The duration is a measurement period, and the unit is 10 milliseconds;

(5) The traffic threshold can be configured through the user interface. The value range can be 0 to 0xFFFFFF.

The setting of the weight value involved in the above traffic threshold is a value obtained by a person skilled in the art based on data analysis. In the embodiment of the present invention, related parameters such as a measurement period may be adjusted according to actual conditions.

In another optional implementation manner of this embodiment, after the base station is bound to the virtual machine in sequence according to the sorting information that is queried according to the mapping relationship, the method in this embodiment may further include:

Step 110-1: When adding a new base station, determine whether there is a virtual machine binding with a base station in a coverage area of the location area to which the new base station belongs;

Step 110-2: When the result of the determination is that the virtual machine is bound to the base station in the coverage area of the location area to which the new base station belongs, the virtual base station is bound to the base station in the coverage area of the location area to which the new base station belongs. Machine binding;

It should be noted that when there are multiple virtual machines bound by the base station included in the location area, the total number of carrier frequencies of all base stations in the location area bound by the virtual machine is sorted from large to small, and the first one is sequentially searched. A conditional virtual machine (the total number of carrier frequencies of all the base stations bound to the virtual machine does not exceed the maximum carrier frequency that the virtual machine can accommodate). If found, bind the new virtual machine to the virtual machine. If not found, bind to the most idle virtual machine.

Step 110-3: When the result of the determination is that the virtual machine is not bound to the base station in the coverage area of the location area to which the new base station belongs, the virtual machine with the lowest idle value is bound to the new base station, where the idle value is The ratio of the number of carrier frequencies being processed by the virtual machine to the upper limit of the number of carriers processed by the virtual machine.

When the new base station is added, the binding operation is also performed by the step 110-1 to the step 110-3, and the binding operation may bind the new base station to the base station within the coverage area of the location area to which the base station belongs. The virtual machine is bound, and if the virtual machine bound to the base station within the coverage area of the location area to which the new base station belongs is not found, the virtual machine selected from the idle virtual machine is tied to the new base station. set.
