It in one implementation, can be with when not having directly to carry the IMSI of roaming terminal in network connecting request The mark of roaming terminal is determined according to the content in step S202, or true according to the communication network that the roaming terminal last time is accessed Determine the mark of roaming terminal.

S203b, the IMSI that roaming terminal is determined according to the GUTI of roaming terminal.

Specifically, since the GUTI of roaming terminal corresponds to unique roaming terminal in a communication network, and roaming terminal IMSI also corresponds to unique roaming terminal, and therefore, there are a kind of one-to-one correspondence by the GUTI of the IMSI of roaming terminal and roaming terminal Relationship.The IMSI of roaming terminal can be directly determined according to the GUTI of roaming terminal.

S203c, the PLMN that ownership place operator is determined according to the IMSI of roaming terminal.

Specifically, the IMSI of roaming terminal has been determined, ownership place operation can be directly determined according to the IMSI of roaming terminal The PLMN of quotient.In network connecting request, roaming terminal carries the IMSI of roaming terminal, is returned according to the IMSI of roaming terminal calculating The PLMN of possession operator.The coding rule of the IMSI of roaming terminal are as follows: MCC+MNC+MSIN, the PLMN=of ownership place operator MCC+MNC。

It should be noted that in the embodiment of the present invention in order to determined according to network connecting request the mark of roaming terminal with And the mark of ownership place operator, judge whether roaming terminal is the terminal tested in target communication network.In a kind of reality In existing mode, it may not be necessary to determine the mark of roaming terminal and the mark of ownership place operator, directly to roaming terminal into Row judgement.When the mark of the mark and ownership place operator that do not need determining roaming terminal, the embodiment of the present invention is provided Method, S201-S203 can not be executed, and directly start execute S204-S205:

The roaming terminal of S204, with judging request the access roaming communication network of operator, if for returning for roaming terminal Possession operator is used for the terminal tested in target communication network.

Wherein, between roaming place operator and the ownership place operator of roaming terminal belonging to target communication network, exist The roaming agreement of other communication networks in addition to target communication network, and the roaming agreement of target communication network is not present.

Illustratively, target communication network includes 5G network, other communication networks include 4G network.

With the judging request access roaming roaming terminal of the communication network of operator A, if be the ownership place of roaming terminal Operator B is used for the terminal tested in the 5G network of roaming place operator A.Roaming place operator A and ownership place operation There are 4G roaming agreements between quotient B, and 5G roaming agreement is not present.

In a kind of implementation of the present embodiment, judge that the roaming of with the requesting access roaming communication network of operator is whole End, if be the terminal that the ownership place operator of roaming terminal is used to be tested in target communication network, specifically include step Rapid S204a:

S204a, judge that ownership place operator identifies whether to be recorded in first database, and judge roaming terminal It identifies whether to be recorded in the second database.

Wherein, first database, for recording the roaming agreement between the operator of roaming place there are target communication network Operator mark.

Second database, for being recorded in the terminal iidentification tested in target communication network.

Specifically, judge ownership place operator identifies whether to be recorded between the operator of roaming place that there are destinations traffics Among the mark of the operator of network protocol, and judge identifying whether to be recorded in target communication network and carrying out for roaming terminal Among the terminal iidentification of test.The mark of ownership place operator may be recorded in first database, it is also possible to not recorded.It is unrestrained The mark of trip terminal may be recorded in the second database, it is also possible to not recorded.

Illustratively, ownership place operator is identified as 46001, and roaming terminal is identified as 8618611111111.Judgement Whether 46001 be recorded in first database, judges whether 8618611111111 be recorded in the second database.

In a kind of implementation of the present embodiment, judge that the roaming of with the requesting access roaming communication network of operator is whole End, if be the terminal that the ownership place operator of roaming terminal is used to be tested in target communication network, specifically further include Step S204b-S204d:

S204b, first identifier is determined from first database, and second identifier is determined from the second database.

Specifically, including that multiple there are the roaming of target communication network associations between the operator of roaming place in first database The mark of the operator of view determines first identifier from first database, that is, determines a mark in first database. Include multiple terminal iidentifications tested in target communication network in second database, second is determined from the second database Mark, that is, determine a mark in the second database.

If the mark of S204c, ownership place operator includes each feature of first identifier, it is determined that ownership place operator Mark and first identifier successful match.

Wherein, first identifier is an operator identifier in first database.

Specifically, by a mark (first identifier) progress in the mark and first database of ownership place operator Match.

Illustratively, ownership place operator is identified as 46001, first identifier 46001.In the present embodiment, 46001 It include two features in=460+01, that is, first identifier, two features include MNC and MCC, that is, 460 and 01, i.e., PLMN=MNC+MCC.The mark 46001 of ownership place operator includes each feature of first identifier 46001, determines that ownership place is transported Seek the mark 46001 and 46001 successful match of first identifier of quotient.If ownership place operator is identified as 46001, first identifier is 46000, the mark of ownership place operator does not include each feature of first identifier, it is determined that the mark of ownership place operator and the One mark matching is unsuccessful.

If the mark of S204d, roaming terminal includes each feature of second identifier, it is determined that the mark of roaming terminal and the Two mark successful match.

Wherein, second identifier is a terminal iidentification in the second database.

Specifically, the mark of roaming terminal is matched with a mark (second identifier) in the second database.

Illustratively, roaming terminal is identified as 8618611111111, second identifier 8618611111111.In this reality It applies in example, includes three features, three feature packets in 8618611111111=86+186+11111111, that is, second identifier Include CC, NDC, SN, that is, 86,186,11111111, i.e. MSISDN=CC+NDC+SN.The mark of roaming terminal 8618611111111 include each feature of second identifier 1818611111111, determines the mark of roaming terminal 8618611111111 with 8618611111111 successful match of second identifier.If roaming terminal is identified as 8618611111111, Second identifier is 8618611111119, and the mark of roaming terminal does not include each feature of second identifier, it is determined that roaming terminal Mark matched with second identifier it is unsuccessful.

In an implementation of the embodiment of the present invention, the second database further includes carrying out in target communication network The number section of test.

If the mark of roaming terminal includes each feature of third mark, it is determined that the mark and third of roaming terminal identify Successful match.Wherein, third is identified as a number section in the second database.

Specifically, the mark of roaming terminal is matched with a mark (third mark) in the second database.

Illustratively, roaming terminal is identified as 8618611111111, and third is identified as 1861111,186111 is one Number section.In embodiments of the present invention, using the preceding 4-digit number of the part SN in MSISDN as a feature, this feature is for indicating Geographical location belonging to roaming terminal.The mark 8618611111111 of roaming terminal includes each spy of third mark 1861111 Sign determines that the mark 8618611111111 of roaming terminal and third identify 1861111 successful match.If the mark of roaming terminal It is 8618611111111, third is identified as 1860000, and the mark of roaming terminal does not include that each feature of third mark is then true Determine roaming terminal mark and third mark match it is unsuccessful.

If S205, roaming terminal are not the ownership place operators of roaming terminal for being tested in target communication network Terminal, then by roaming terminal access roaming in multiple communication networks of operator network formats lower than target communication network Communication network.

Illustratively, if roaming terminal is not the ownership place operator B of roaming terminal for being surveyed in 5G network The terminal of examination, then by roaming terminal access roaming 4G network (i.e. multiple communication networks of roaming place operator A of operator A Middle network formats are lower than the communication network of target communication network).

In a kind of implementation of the present embodiment, if the ownership place operator that roaming terminal is not roaming terminal is used for The terminal tested in target communication network, then by roaming terminal access roaming network in multiple communication networks of operator Standard is lower than the communication network of target communication network, specifically includes step S205a:

If not having to record the mark of ownership place operator in S205a, first database, and do not remember in the second database The mark of roaming terminal is recorded, then by roaming terminal access roaming network formats grade is lower than in multiple communication networks of operator The communication network of target communication network.

Specifically, if the mark of ownership place operator is not present in first database, and there is no unrestrained for the second database The mark of terminal is swum, then by roaming terminal access roaming network formats grade is lower than target in multiple communication networks of operator The communication network of communication network.

If first database has recorded in the mark or the second database of ownership place operator and has recorded roaming terminal Mark, then by roaming terminal access roaming the target communication network of operator.If roaming terminal possesses access, target is logical Network formats are double lower than the communication network of target communication network in communication network and multiple communication networks of roaming place operator Connection ability, then by roaming terminal access roaming multiple communications of the target communication network of operator and roaming place operator Network formats are lower than the communication network of target communication network in network.

Illustratively, the mark 46001 of ownership place operator B is not present in first database, and in the second database There is no the marks 8618611111111 of roaming terminal, then by roaming terminal access roaming the 4G network (target of operator A Communication network includes the 5G network of roaming place operator, and network formats grade is lower than in multiple communication networks of roaming place operator The communication network of target communication network includes the 4G network of roaming place operator).

If there are the marks 46001 of ownership place operator B in first database, and there is roaming in the second database The mark 8618611111111 of terminal, then by roaming terminal access roaming the 5G network of operator A (if roaming terminal is gathered around The doubly-linked of the 4G network of the network 5G of operator A and roaming place operator A leads to ability with having access roaming, then by roaming terminal Access roaming ground the 5G network of operator A and the 4G network of roaming place operator A).

In an implementation of the embodiment of the present invention, if not having to record the mark of ownership place operator in first database Know, and do not have to record the mark of roaming terminal, this method in the second database further include:

The target communication network function of logical roaming terminal is not put in roaming place operator.

Illustratively, do not have to record the mark of ownership place operator in first database, and do not have in the second database Record the mark of roaming terminal.Roaming place operator does not put the 5G function of roaming terminal logical.MME does not start the selection of 5G gateway and expands Open up function: i.e. tracking area (trace area, TA) fully qualified domain name (fully qualified of MME construction inquiry SGW Domain name, FQDN) when, TA FQDN does not carry the parameter that filling forms are " x-3gpp-sgw:x-s5-gtp+nc-nr " "Service Parameters".When the APN FQDN of construction inquiry PGW, it is " x-3gpp- that APN FQDN, which does not carry filling forms, The parameter " Service Parameters " of sgw:x-s5-gtp+nc-nr ".MME is according to TA FQDN and APN FQDN inquiry field Name system (domain name system, DNS), query result returns to non-5G SGW (common 4G SGW) and non-5G PGW is (general Logical 4G PGW) Internet protocol address (internet protocol address, IP).

In a kind of implementation of the present embodiment, if the ownership place operator that roaming terminal is not roaming terminal is used for The terminal tested in target communication network, then by roaming terminal access roaming network in multiple communication networks of operator Standard is lower than the communication network of target communication network, specifically further includes step S205b:

If the mark of S205b, ownership place operator matches unsuccessful, and the mark of roaming terminal and the with first identifier Two mark matchings are unsuccessful, then by roaming terminal access roaming network formats grade is lower than in multiple communication networks of operator The communication network of target communication network.

Specifically, if the mark of ownership place operator does not include each feature of first identifier, and roaming terminal Mark does not include each feature of second identifier, then by roaming terminal access roaming network in multiple communication networks of operator Standard grade is lower than the communication network of target communication network.

If the mark and second identifier of the mark of ownership place operator and first identifier successful match or roaming terminal With success, then by roaming terminal access roaming the target communication network of operator.

Illustratively, ownership place operator B is identified as 46001, first identifier 46002.Roaming terminal is identified as 8618611111111, second identifier 8618611111119.The mark 46001 and first identifier 46002 of ownership place operator B Match it is unsuccessful, and the mark 8618611111111 of roaming terminal matched with second identifier 8618611111119 it is unsuccessful, Then by roaming terminal access roaming the 4G network of operator A.

If ownership place operator B's is identified as 46001, first identifier 46001.Or roaming terminal is identified as 8618611111111, second identifier 8618611111111.The mark 46001 and first identifier 46001 of ownership place operator B Successful match.Or the mark 8618611111111 of roaming terminal and 8618611111111 successful match of second identifier, then will Roaming terminal access roaming operator A 5G network.

In an implementation of the embodiment of the present invention, if the ownership place operator that roaming terminal is not roaming terminal is used In the terminal tested in target communication network, then by roaming terminal access roaming in multiple communication networks of operator Network formats are lower than the communication network of target communication network, specifically further include:

If the mark of ownership place operator matches unsuccessful with first identifier, and the mark of roaming terminal and third are identified Match unsuccessful, then by roaming terminal access roaming network formats grade is led to lower than target in multiple communication networks of operator The communication network of communication network.

Specifically, if the mark of ownership place operator does not include each feature of first identifier, and roaming terminal Mark does not include each feature of third mark, then by roaming terminal access roaming network in multiple communication networks of operator Standard grade is lower than the communication network of target communication network.

If mark and the third mark of the mark of ownership place operator and first identifier successful match or roaming terminal With success, then by roaming terminal access roaming the target communication network of operator.

Illustratively, ownership place operator B is identified as 46001, first identifier 46002.Roaming terminal is identified as 8618611111111, third is identified as 1860000.The mark 46001 of ownership place operator B matches not with first identifier 46002 Success, and the mark 8618611111111 of roaming terminal and third identify 1860000 match it is unsuccessful, then by roaming terminal Access roaming operator A 4G network.

If ownership place operator B's is identified as 46001, first identifier 46001.Or roaming terminal is identified as 8618611111111, third is identified as 1861111.The mark 46001 of ownership place operator B is matched into first identifier 46001 Function.Or the mark 8618611111111 of roaming terminal and third identify 1861111 successful match, then access roaming terminal The 5G network of roaming place operator A.
