As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 1 is a flowchart of a method for disaster recovery HSS subscription information according to an embodiment of the present invention, and as shown in fig. 1, the method includes:

step 101, judging whether the home HSS of the UE can be accessed normally according to the attachment request message sent by the UE.

And 102, if the home HSS of the UE cannot be normally accessed, judging whether the number section of the UE is configured.

And 103, if the number segment of the UE is not configured, inquiring an MME where the emergency information of the UE is located through a DNS, and acquiring the emergency subscription information of the UE from the MME where the emergency information is located so that the UE can perform normal communication through the emergency subscription information.

The method for disaster recovery HSS subscription information provided by the embodiment of the invention can realize the scene that HSS cannot provide service due to various reasons of MME near-end disaster recovery, thereby greatly improving the robustness of the network.

Fig. 2 is a flowchart of a method for disaster recovery of HSS subscription information according to another embodiment of the present invention, as shown in fig. 2, the method includes:

step 201, according to the attachment request message sent by the UE, determining whether the home HSS of the UE can be normally accessed, if not, executing step 202; if yes, go to step 205.

In the embodiment of the invention, the MME where the UE is located executes the following steps. It should be noted that the MME where the UE is located may include a local MME and a roaming MME. For example, when a UE with tianjin number segment is currently in beijing, the MME where the UE is currently located is the MME in beijing, and the local MME of the UE is the MME in tianjin.

In the embodiment of the invention, if the home HSS capable of normally accessing the UE is judged, the home HSS of the current UE is in a state of normally providing services; and if the home HSS of the UE cannot be normally accessed is judged, the home HSS of the current UE is in a state of being incapable of normally providing the service. The reason for the current UE's home HSS failing to provide services normally may include a failure of the HSS itself or a failure of a network connected to the HSS.

In the related art, the schemes of disaster tolerance HSS subscription information are all concentrated on the HSS side, that is, the availability of HSS services is ensured by performing redundant backup on the HSS, for example, by creating a plurality of backed-up HSS, and the embodiment of the present invention provides a method of disaster tolerance HSS subscription information for a current home HSS of a UE in a state where the home HSS cannot provide services normally.

In the embodiment of the present invention, before step 201, the method further includes: and acquiring the number segment of the user, and configuring the number segment of the user to the corresponding MME.

In the embodiment of the present invention, the number segment is used to indicate the first 3 digits of the mobile phone number of the user, for example, the number segment of the user may include 139.

In the embodiment of the present invention, the premise that the user can perform normal communication is that the number segment of the user needs to be configured to the corresponding MME, that is, the number segment of the user needs to be set as the number segment of the MME coverage area corresponding to the service, where the corresponding MME usually belongs to the MME to which the number segment of the user belongs, for example, the number segment of the user is 155, and the number segment belongs to the number segment of tianjin, so that the number segment is configured to the MME of tianjin. It should be noted that each MME may be configured with multiple number segments, for example, each MME may be configured with 100 number segments. In addition, a specific number segment may be configured to a designated MME.

After the number segment of the user is configured to the corresponding MME, when the user in the number segment performs a service operation in the corresponding MME, the corresponding MME can create or update the emergency subscription information and the emergency authentication information of the user in the emergency subscription information table using the subscription information and the authentication information of the user in the subsequent steps.

Step 202, judging whether a number segment of the UE is configured, if not, executing step 203; if yes, go to step 204.

In the embodiment of the invention, the premise that the user can carry out normal communication is that the MME where the user is located needs to configure the number segment configuration of the user. Therefore, if the MME where the UE is located is judged not to be configured with the number segment of the UE, the MME where the UE is located is indicated to comprise a roaming MME, and the number segment of the UE is not configured in the roaming MME; if the MME where the UE is located configures the number segment of the UE is judged, the MME where the UE is located includes a local MME, and the local MME is configured with the number segment of the UE.

In the embodiment of the present invention, before step 202, the method further includes:

step 201a, establishing an emergency subscription information table according to a plurality of fields, user emergency subscription information items and user emergency authentication information items in the acquired mobility contexts of a plurality of users.

In an embodiment of the present invention, the plurality of fields in the mobility context may include, for example, a Subscriber International Mobile Subscriber Identity (IMSI) field and a Subscriber Mobile station International ISDN number (MSISDN) field. The MSISDN is a number which is called by a calling user for calling a mobile user in a GSM PLMN and is used as a fixed network PSTN number; is a number that uniquely identifies a mobile subscriber in a public telephone network switching network numbering plan.

Step 201b, judging whether the function of the emergency contract information table is started, if so, continuing to execute step 202; if not, the process is ended.

In this embodiment of the present invention, after the step 201a, the emergency subscription information table may include emergency information of a plurality of users, where the emergency information includes subscription emergency information of the users and authentication emergency information of the users. Since the emergency information of the UE is stored in the emergency subscription information table, after the function of the emergency subscription information table is determined to be enabled, the MME where the emergency information of the UE is located can be queried through a Domain Name System (DNS) in the subsequent step 203.

Step 203, inquiring the MME where the emergency information of the UE is located through the DNS, and acquiring the emergency subscription information of the UE from the MME where the emergency information is located, so that the UE can perform normal communication through the emergency subscription information.

In the embodiment of the invention, the DNS generally serves a domain name system of the province where the UE is located.

In the embodiment of the present invention, the step of querying, by using a DNS, an MME where the emergency information of the UE is located specifically includes the following steps:

step 2031, obtaining the IMSI field of the user in the emergency information of the UE.

In the embodiment of the invention, the emergency information further comprises a user IMSI field, and the user IMSI field comprises a field in the mobility context.

Step 2032, judging whether the IMSI field of the user comprises the IMSI field of the province user or the IMSI field of the province user, if the IMSI field of the user comprises the IMSI field of the province user, executing step 2033; if the subscriber IMSI field includes the foreign subscriber IMSI field, go to step 2034.

In the embodiment of the present invention, if the IMSI field of the user includes the IMSI field of the user of this province, it indicates that the DNS of the province where the UE is located is the DNS of the province where the UE is located, so the subsequent step 2033 is executed to obtain the device address of the MME to which the number segment of the UE belongs; if the IMSI field of the user includes the IMSI field of the out-province user, it indicates that the DNS of the province where the UE is located is not the DNS of the province where the UE belongs, so that the subsequent step 2034 is performed to acquire the DNS to which the number segment of the UE belongs by analyzing the IMSI field of the user through the DNS of the previous stage.

Step 2033, analyzing the IMSI field of the user through DNS, acquiring the device address of the MME to which the UE belongs, and querying the MME where the emergency information of the UE is located according to the device address.

In this embodiment of the present invention, before executing step 2033, the method further includes: DNS inside each province network is configured with IMSI number segment analysis data of the province, and the equipment address of each MME in the MME pool to which the number segment belongs can be obtained by analyzing the number segment of the province, wherein the equipment address comprises an S10 interface address.

Since the IMSI field of the user includes the IMSI field of the user in this province, that is, the DNS of the UE home province is configured with the resolution data of the IMSI field of the user, the DNS resolves the IMSI field of the user by executing step 2033, so that the device address of the MME to which the number field of the UE belongs can be acquired.

Step 2034, the user IMSI field is analyzed through the upper level DNS to obtain the DNS to which the UE number segment belongs.

In this embodiment of the present invention, before executing step 2034, the method further includes: DNS inside each province network is configured with analysis data of IMSI number sections of the external provinces, and the DNS of the upper level can be obtained by analyzing the number section of the province. Wherein, the DNS at the upper level is used to indicate a higher level DNS than the DNS where the UE is located.

It should be noted that the DNS at the upper level configures pointing data of each province number segment, so that the DNS to which the number segment of the UE belongs can be acquired by analyzing the IMSI field of the user through the DNS at the upper level, and the MME device address storing the emergency information of the UE is acquired.

In the embodiment of the present invention, for example, the UE in jilin is located in tianjin at this time, that is, the DNS where the UE is currently located is the DNS in tianjin, and the number segment of the UE in jilin is resolved by the DNS in tianjin, so that the DNS in the previous stage can be obtained, for example, the DNS in the previous stage is the DNS in beijing. By executing step 2034, i.e. by using the DNS in beijing to resolve the IMSI field of the user, the DNS with the UE number segment as the DNS of gilin is obtained.

Step 2035, the IMSI field of the user is analyzed through the DNS to which the number segment of the UE belongs, the device address of the MME to which the number segment of the UE belongs is acquired, and the MME in which the emergency information of the UE is located is queried according to the device address.

In the embodiment of the present invention, acquiring the emergency subscription information of the UE from the MME where the emergency information is located specifically includes the following steps:

step 2036, sending an inquiry instruction of the emergency information to the MME where the emergency information of the UE is located.

In the embodiment of the present invention, the MME where the emergency information of the UE is located may be a local MME, or may be another MME in the same MME pool as the local MME, which is not limited in the present invention.

Step 2037, acquiring the emergency information of the user returned by the MME where the emergency information of the UE is located.

In the embodiment of the present invention, step 2037 is executed to enable the MME where the UE is located to continue providing services for the user by acquiring the emergency subscription information of the UE.

In the embodiment of the present invention, further, the method further includes: and if the emergency subscription information of the UE is not acquired from the MME where the emergency information is located, ending the process.

And 204, inquiring emergency information of the UE in a pre-established emergency subscription information table, wherein the emergency information comprises the emergency subscription information so that the UE can carry out normal communication through the emergency subscription information.

In the real-time example of the present invention, in the case that the MME where the UE is located fails to normally access the home HSS of the UE, if the MME where the UE is located is configured with the number segment of the UE, it indicates that the MME where the UE is located includes a local MME, and the local MME is configured with the number segment of the UE.

Step 205, judging whether the number segment of the UE is configured, if so, executing step 206; if not, the process is ended.

In the embodiment of the present invention, when the MME where the UE is located can normally access the home HSS of the UE, it indicates that the home HSS of the UE is in a state of normally providing a service, and therefore step 205 needs to be executed to further determine whether the MME where the UE is located configures a number segment of the UE, and if the MME where the UE is located configures a number segment of the UE, it indicates that the MME where the UE is located can provide a service for the UE, that is, subsequent step 206 can be executed to obtain emergency subscription information of the UE, so that normal communication can be achieved.

And step 206, creating or updating the emergency information of the UE in the pre-established emergency subscription information table, and acquiring the emergency subscription information from the emergency information so that the UE can perform normal communication through the emergency subscription information.

Step 2063, sharing the emergency information to other MMEs except the MME where the UE is located in the current MME pool.

In the embodiment of the present invention, the other MMEs may include backup MMEs. The step 2063 is executed to make the data information of the emergency subscription information table in each MME of the same MME pool identical. I.e. the emergency information of the users in each MME is the same. Step 2063 is executed to avoid that when a failure of disaster recovery is caused by damage of one MME, other MMEs in the same MME pool can provide services for the user, so that the user can communicate normally, thereby improving the security of the service.

It should be noted that, the manner of executing step 2063 may include sharing to MME in other MME pools through S10 interface.

Step 2064, sharing the emergency information to the MME in other MME pools except the current MME pool.

The step 2064 is executed to make the data information of the emergency subscription information table in each MME be the same between different MME pools. That is, the emergency information of the user in each MME is the same between different MME pools. Step 2064 is executed to avoid that when a failure of disaster recovery is caused by damage of one MME pool, the MMEs in other MME pools can provide services for the user, so that the user can communicate normally, thereby improving the security of the service.

Step 2065, if the emergency information of the UE is updated through the pre-established emergency subscription information table, generating the updated emergency subscription information and the updated emergency authentication information according to the acquired subscription information and the authentication information of the UE.

In the embodiment of the invention, the MME where the UE is located can initiate the bearing establishment request of the corresponding service for the user by establishing the session request according to the updated emergency subscription information of the user by generating the updated emergency subscription information and the updated emergency authentication information of the UE, thereby ensuring the safety of the service.

Step 2066, updating the emergency information of the corresponding UE in the pre-established emergency subscription information table according to the updated emergency subscription information and the updated emergency authentication information.

In the embodiment of the invention, when each MME in different MME pools subsequently updates the emergency information of the UE in the emergency subscription information table, the updated emergency subscription information and the updated emergency authentication information acquired by the MME where the UE is located are used as the standard.

Step 2067, sharing the updated emergency information to other MMEs except the MME where the UE is located in the current MME pool.

In the embodiment of the present invention, the specific implementation process of step 2067 can be referred to as step 2063.

Step 2068, sharing the updated emergency information to the MME in other MME pools except the current MME pool. In the embodiment of the present invention, the specific implementation process of step 2068 can be referred to as step 2064.

In the embodiment of the present invention, further, the method further includes:

step 301, if the service provided by the home HSS of the UE cannot be used, adding a tag field in the mobility context, where the tag field is used to tag whether the UE is an emergency subscriber.

In the embodiment of the present invention, the condition that the MME where the UE is located cannot use the service provided by the home HSS of the UE may include that the MME where the UE is located cannot normally access the HSS, or that the MME where the UE is located fails to acquire the authentication information of the UE.

Step 302, if the emergency information of the UE is not queried in the pre-established emergency subscription information table, or if the MME where the emergency information of the UE is located is queried through the DNS, adding an identifier to a label field corresponding to the UE.

In this embodiment of the present invention, for example, the manner of adding the identifier in the tag field corresponding to the UE may include: the flag field "if emergency subscriber" of the UE is marked as "yes".

In the embodiment of the present invention, the specific steps of querying the MME where the emergency information of the UE is located through the DNS may refer to steps 2031 to 2035.

And 303, if the service provided by the home HSS of the UE is normally used, inquiring whether the UE is an emergency subscriber or not through the identifier according to a set period, and if the UE is the emergency subscriber, sending an detach instruction to the UE so that the UE can register again according to the detach instruction.

In the technical scheme provided by the embodiment of the invention, when the home HSS of the UE cannot provide services, the MME where the UE is located can inquire the emergency subscription information table of the UE or inquire the emergency subscription information tables in other MMEs to provide network services for the user, so that the problem that the user cannot normally use the network to cause large-scale service influence is solved, and the service safety is improved.
