In the prior art, limited by inter-slice transmission conditions (for example, the user capacities of the respective slices are different), services in the respective slices can only be carried through SGW devices in the respective slices, and the service disaster tolerance in the respective slices can only basically satisfy the service disaster tolerance when 1 to 2 SGW devices of the same communication device manufacturer in the SGW POOL are faulty or damaged, when a plurality of SGW devices in the SGW POOL of a certain slice are faulty or damaged, the service disaster tolerance in the slice cannot be realized, but limited by the inter-slice transmission conditions, the service disaster tolerance in the slice cannot be realized in the prior art, so that the service interruption of the slice is caused.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
It should be noted that the parcel mentioned in each embodiment of the present invention may be a parcel determined according to an administrative division, as described in the background art, or a geographical area with a certain physical range may be divided into parcels according to actual needs, or a parcel may be divided based on a location of a network element device of a mobile network, or certainly, a parcel determined in other reasonable division manners may also be used. Those skilled in the art should understand that the fragment referred to in the embodiments of the present invention is a fragment that is divided in advance, and Service Gateway (SGW) devices in each fragment form an SGW POOL (SGW POOL) to implement service disaster tolerance in each fragment, and the user capacity of each fragment is determined in advance. Therefore, the present invention will be specifically described with reference to the following examples.
As shown in fig. 1, the embodiment discloses a method for sharing inter-chip user capacity, which may include the following steps 101 to 103:
101. after determining to share the inter-slice user capacity, respectively configuring transmission parameters of each base station corresponding to a target Tracking Area Code (TAC) of a shared source slice with a serving gateway SGW pool and a target mobility management entity MME pool of a shared target slice, where the transmission parameters are used for communication connection.
The main execution body of the embodiment is a server, and the server can be arranged in a network management system of a communication equipment operator. In this embodiment, the determining to perform inter-tile user capacity sharing may be manually triggered when it is determined that inter-tile user capacity sharing is required, that is, the executing subject of this embodiment may determine to perform inter-tile user capacity sharing after receiving a manually input triggering instruction. Triggering conditions that require inter-tile user capacity are for example: in the prior art, an SGW pool capacity early warning module or an SGW pool fault early warning module gives an alarm, and manually determines whether hardware capacity expansion is feasible or not, if so, inter-segment user capacity sharing is not needed, and if not, for example, when capacity expansion cannot be timely performed due to various reasons, inter-segment user capacity sharing is needed.
In this embodiment, when it is determined manually that inter-slice user capacity sharing needs to be performed, a target TAC sharing a source slice (to which services of base stations corresponding to the target TAC are to be transferred out) and a target MME pool sharing a target slice are usually specified based on an actual situation, and since a plurality of MME pools are usually located in one slice, it is necessary to manually specify the target MME pool to accommodate user handover according to the actual situation, and an SGW pool sharing the target slice is used to carry services sharing the source slice.
After the transmission parameter configuration is performed in step 101, configuration information is generated. In practical application, after the configuration information is generated, the server can send the configuration information to the corresponding base station, MME and routing device of Packet Transport Network (PTN), so that the base station, MME and routing device modify the configuration by themselves; in practical applications, after the configuration information is generated, the base station, the MME and the routing device may be configured manually.
In this embodiment, the inter-cell base station may also be configured with transmission parameters manually in advance to implement the inter-cell base station to communicate with the MME and the SGW. Namely, the interconnection of S1-U interfaces between the base stations of the various cells and the SGW is realized.
102. After the configuration of the transmission parameters is completed, modifying original corresponding information of the target TAC of the shared source fragment area stored in a Domain Name System (DNS) server, so that the target TAC corresponds to the SGW pool and the target MME pool of the shared target fragment area, respectively.
In this embodiment, the execution main body of this embodiment is connected to the DNS server, and may directly modify data stored in the DNS server, and may also send a modification instruction message to the DNS server, so that the DNS server modifies itself based on modification information carried in the modification instruction message, where the modification information is used to indicate that the target TAC corresponds to the SGW pool and the target MME pool of the shared destination slice, respectively.
103. And sending deletion indication information to each MME in the MME pool indicated by the original corresponding information of the target TAC so that each MME deletes the DNS cache, thereby realizing the user capacity sharing among the cell areas.
In this embodiment, the execution main body of this embodiment is connected to each MME of the respective segments, but the DNS cache in each MME cannot be directly modified, so that it is necessary to send deletion instruction information to the MME so that the MME deletes the DNS cache.
In this embodiment, because each MME in the MME pool indicated by the original corresponding information of the target TAC deletes the DNS cache, when a certain user of each base station corresponding to the target TAC initiates a service, the MME in the MME pool cannot query the DNS cache, so as to request the DNS server to acquire DNS data, where the DNS data fed back by the DNS server includes the DNS data modified in step 102 (i.e., the information obtained by modifying the original corresponding information of the target TAC), and because the original corresponding information of the target TAC changes, that is, the target TAC corresponds to the SGW pool and the target MME pool sharing the target parcel, respectively, the service is borne by the SGW pool sharing the target parcel, so that sharing of user capacity among parcels is achieved.
It can be seen that, in the method for sharing user capacity between slice regions disclosed in this embodiment, the inter-slice-region intercommunication is realized by configuring transmission parameters of the shared source slice region and the shared destination slice region, and then the target TAC corresponds to the SGW pool and the MME pool of the shared destination slice region respectively by modifying the target TAC information of the shared source slice region stored in the DNS server, so that when a user of each base station corresponding to the target TAC initiates a service, the user capacity can be carried by the SGW of the shared destination slice region, and thus, the inter-slice user capacity sharing is realized.
In a specific example, the step 101 of configuring transmission parameters of each base station corresponding to the target tracking area code TAC of the shared source parcel with the serving gateway SGW pool and the target mobility management entity MME pool of the shared destination parcel respectively includes:
configuring static routes of all base stations corresponding to the target TAC of the shared source parcel so as to enable all the base stations to be communicated with the SGW pool of the shared target parcel;
and configuring a traffic Control Transmission Protocol (SCTP) link address of each base station corresponding to the target TAC of the shared source fragment area, so that each base station is communicated with the target MME pool of the shared target fragment area.
In this embodiment, each SGW in the SGW pool and each MME in the target MME pool of the target parcel need to be manually and previously ping each base station corresponding to the target TAC to share each SGW in the target parcel.
In a specific example, the modifying, in step 102, original corresponding information of the target TAC of the shared source parcel, which is stored in the domain name system DNS server, specifically includes:
modifying the SGW pool corresponding to the target TAC in the original corresponding information into the SGW pool of the shared target fragment area;
modifying the MME pool corresponding to the target TAC in the original corresponding information into a target MME pool of the shared target fragment area;
wherein the original corresponding information includes an SGW pool corresponding to the target TAC and an MME pool corresponding to the target TAC.
In a specific example, before modifying the original corresponding information of the target TAC of the shared source parcel stored in the domain name system DNS server in step 103, steps 103' and 103 ″ not shown in fig. 1 are further included:
103' and adding the resolution information of the SGW pool of the sharing destination fragment to the resolution file of the sharing source fragment stored in the DNS server.
103 ″ from the TAC resolution file of the shared source film area stored in the DNS server, original corresponding information of the target TAC is queried.
In this embodiment, it is considered that the files stored in the DNS server include two types, one is an analysis file of a parcel, and the other is a TAC analysis file of a parcel, and therefore, the two files need to be modified respectively.
It should be noted that, in order to prevent misoperation and subsequent operation after the shared source partition recovers to normal operation, the DNS data should be backed up first.
In a specific example, after it is determined that the user capacity sharing between the slice regions is stopped, that is, the shared source slice region returns to normal operation, the modified corresponding information of the target TAC of the shared source slice region stored in the DNS server is returned to the original corresponding information.
In this embodiment, the recovery operation specifically includes the following step A, B, C:
A. deleting the analysis information of the SGW pool of the shared target fragment area added in the step 103';
B. deleting the modified corresponding information of the target TAC of the sharing source film area stored in the DNS;
C. and rewriting the original corresponding information which is backed up in advance into the TAC analysis file of the sharing source area.
Meanwhile, deletion indication information should be sent to each MME in the MME pool indicated by the original correspondence information of the target TAC, so that each MME deletes the DNS cache, and further each MME acquires the original correspondence information from the DNS server.
Based on the inter-segment user capacity sharing method disclosed in the above embodiments, considering that different segments may use SGW devices of different communication device operators, when manually specifying a target SGW pool that shares a target segment, the target SGW pool is specified based on the following policy:
firstly, considering each subarea which is the same as an operator of SGW equipment sharing a source subarea; and then, considering the user capacity size of each same fragment of the operator, thereby specifying a target SGW pool sharing the target fragment.
Secondly, considering each subarea different from an operator of the SGW equipment sharing the source subarea; and then, considering the user capacity size of each different fragment of the operator, thereby specifying a target SGW pool sharing the target fragment.
The same technical concept as the inter-tile user capacity sharing method embodiment shown in fig. 1, as shown in fig. 2, this embodiment discloses a server, which may include the following units: a configuration unit 21, a modification unit 22 and a sending unit 23.
