Description

Method and device for judging gateway co-installation

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a method and a device for judging gateway setting.

Background

An Evolved Packet Core (EPC) is mainly composed of a Mobility Management Entity (MME), a serving gateway (S-GW), a packet data gateway (PDN gateway, P-GW), a Home Subscriber Server (HSS) storing subscriber subscription information, and a policy and charging functions (PCRF), where the S-GW and the P-GW are logically separated, and may be physically combined or separately arranged. The routing forwarding between the combined S-GW and the P-GW needs to pass through a bearer network, and the combined S-GW/P-GW changes one hop between networks into one hop in the equipment, so that the time delay caused by the forwarding of the data routing is reduced, the method has the advantages of smaller time delay and higher forwarding efficiency, and the user perception is improved. And simultaneously, the combined S-GW/P-GW mode is also beneficial to reducing the load of the bearing network.

The existing network users generally use the combined S-GW/P-GW network elements. However, there is also a case where the S-GW/P-GW is separately configured when a user is powered on for attachment or Tracking Area Update (TAU), and the occupation ratio is high. Currently, most of the methods determine whether an S-GW/P-GW device is separately configured when a user powers on to attach or moves a TAU based on a network signaling flow. The current network has complex network flow, and for some network emergency situations, the situation of incomplete signaling can occur, and the problem cannot be judged.

301. and acquiring a preset interface ticket in the XDR data of the target user.

The predetermined interface ticket in the XDR data of the target user comprises an address field of a Service Gateway (SGW) and a protocol IP address field interconnected among networks of the user.

When the preset interface ticket is an S1 interface ticket, the address field of the SGW is a service network management USER interface address SGW-GTP-IP field in the S1 interface ticket, and the IP address field of the USER is a USER-IP field in the S1 interface ticket.

For example, the S1 interface ticket in the XDR data of the target user, as shown in table 1 below, obtains an SGW-GTP-IP of 10.100.00.00 (for example only, not representing a real address).

TABLE 1

When the predetermined interface ticket is an S11 interface ticket, before obtaining the predetermined interface ticket in the XDR data of the target user, the method further includes: the TAU ticket or the service request ticket is associated with an S11 interface ticket in XDR data of a local user through the IMSI; the SGW Address field is a service gateway Address SGW Address field in the S11 interface ticket, and the USER IP Address field is a USER-IP field in the S11 interface ticket.

The data processing equipment matches the SGW-GTP-IP field in the S1 interface ticket with the S1 interface address of the SGW to obtain FQDN1, and then searches the SGW identifier according to the configuration parameter table through the FQDN 1; or after the data processing equipment is matched with the S1 interface address of the SGW through the SGW-GTP-IP field in the S1 interface ticket, the identification of the SGW is directly searched in the configuration parameter table through the S1 interface address, wherein the identification of the SGW can be the name or the number of the SGW. For example, when the SGW-GTP-IP field in the S1 interface ticket is 10.100.00.00, as shown in table 2 below, the S1 interface address that can be matched to the corresponding SGW is 10.100.00.00, and the identifier of the SGW, that is, the name of the SGW is AA _ XX _ sae gw011, is queried.

Name of SAEGW	The city of SAEGW	S1 interface address of SAEGW
			AA_XX_SAEGW011	XX	10.100.00.00
AA_XX_SAEGW012	XX	10.100.XX.XX
			AA_XX_SAEGW013	XX	10.100.XX.XX

TABLE 2

And when the preset interface ticket is the S11 interface ticket, the interface address of the SGW is the S11 interface address of the SGW. The data processing equipment matches an SGW Address field in an S11 interface ticket with an S11 interface Address of an SGW to obtain FQDN1, and then searches an SGW identifier according to a configuration parameter table through FQDN 1; or after the data processing equipment is matched with the S11 interface address of the SGW through the SGW-GTP-IP field in the S11 interface ticket, the identification of the SGW is directly searched in the configuration parameter table through the S11 interface address, wherein the identification of the SGW can be the name or the number of the SGW.

303. Matching the first 16 bits of the user IP address field in the preset interface ticket with the IP PooL corresponding to NET APN configured by PGW in XDR data of the local user to obtain a second full-name domain name FQDN 2; the identification of the PGW selected by the target user is queried by FQDN 2.

Wherein the identification of the PGW may be the name or number of the PGW.

304. And combining the SGW identifier and the PGW identifier selected by the target user to obtain the target identifier.

The identification of the SGW may be the name of the SGW or the number of the SGW, and the identification of the similar PGW may be the name of the PGW or the number of the PGW. If the identifier of the SGW may be the name of the SGW and the identifier of the PGW may be the name of the PGW, the target identifier is a combination of the name of the SGW and the name of the PGW; similar identification of SGWs is the number of the SGW and identification of PGWs is the number of the PGW, then the target identification is a string of numbers that are a combination of the number of the SGW and the number of the PGW.

305. And inquiring in a combined list of the combined SGW identifier and the combined PGW identifier according to the target identifier, and if the target identifier is inquired, determining that the SGW and the PGW selected by the target user are combined.

the processing module is used for combining the SGW identifier and the PGW identifier selected by the target user and obtained by the matching module to obtain a target identifier;

and the query module is used for querying in a combined list of the combined SGW identifier and PGW identifier according to the target identifier obtained by the processing module, and if the target identifier is queried, determining that the SGW and the PGW selected by the target user are combined.

7. The apparatus for determining gateway convergence according to claim 6,

the preset interface ticket is an S1 interface ticket, the address field of the SGW is a service network management USER interface address SGW-GTP-IP field in the S1 interface ticket, and the IP address field of the USER is a USER-IP field in the S1 interface ticket;

the interface address of the SGW is the S1 interface address of the SGW.

8. The apparatus for determining gateway convergence according to claim 6,

the interface address of the SGW is an S11 interface address of the SGW;

before acquiring the predetermined interface ticket in the XDR data of the target user, the matching module is further configured to associate the TAU ticket or the service request ticket with the S11 interface ticket in the XDR data of the local user through the international mobile subscriber identity IMSI.

9. The apparatus for determining gateway convergence according to claim 6,

the acquisition module is also used for acquiring XDR data of a user.

10. The apparatus for determining gateway convergence according to claim 9,

the processing module is further configured to delete abnormal data and repeated data in the XDR data of the user;

the processing module is further configured to filter out XDR data of a local user from the XDR data of the user through an IMSI, where the target user is any one of the local users.

11. A device for judging gateway closing is characterized by comprising a communication interface, a processor, a memory and a bus; the memory is used for storing computer execution instructions, the processor is connected with the memory through the bus, and when the device for judging gateway conjunction runs, the processor executes the computer execution instructions stored in the memory, so that the device for judging gateway conjunction executes the method for judging gateway conjunction according to any one of claims 1-5.

12. A computer storage medium comprising instructions that, when executed on a computer, cause the computer to perform a method of determining a gateway contract as claimed in any of claims 1-5.
