Description

Data processing method, server and network element

Technical Field

The present invention relates to data processing technologies, and in particular, to a data processing method, a server, and a network element.

Background

The roaming mechanism of the existing second generation/third generation/fourth generation mobile communication (2G/3G/4G) network is as follows:

after a roaming user registers to a visited service network element, such as an MSC, an MME or an SGSN, at a roaming place, the roaming user performs location registration to a home subscriber HSS or HLR of the roaming user, and meanwhile, acquires user subscription data of the roaming user from the home subscriber HSS or HLR, and in a 4G network, when the roaming user establishes a session, it is further required to notify a PCRF of the home subscriber of the roaming user, acquire a service policy of the roaming user, and download the service policy to a PCEF of the roaming place, so that a session process of the roaming user is controlled at the roaming place. Further, when the roaming user moves in the roaming place and changes the visited service network element, the home HSS or HLR of the roaming user and the PCRF must be revisited to retrieve the user subscription data and the service policy corresponding to the roaming user, so that when the roaming user changes the visited service network element frequently in the visited place, roaming signaling is increased, and since the processes of acquiring the user subscription data and the service policy are the same, the session efficiency of the roaming user is reduced, and the above processes are not simplified by using the flow under the fifth mobile communication (5G) network architecture.

Detailed Description

So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Example one

FIG. 1 is a first schematic flow chart illustrating an implementation of a data processing method according to an embodiment of the present invention; the method is applied to a roaming user server; as shown in fig. 1, the method includes:

step 101: acquiring user subscription data and a service strategy corresponding to at least one roaming user from a home network, and storing the user subscription data and the service strategy corresponding to the at least one roaming user;

step 102: acquiring first position information and second position information corresponding to the at least one roaming user from a roaming service network element and a roaming session management network element, and recording the first position information and the second position information corresponding to the at least one roaming user; the first location information is used for representing the identifier of the roaming service network element currently visited by the roaming user; the second location information is used for representing the identifier of the roaming session management network element currently accessed by the roaming user;

step 103: according to the first position information and the second position information corresponding to the at least one roaming user, distributing user subscription data and a service strategy corresponding to the at least one roaming user so as to assist a roaming service network element and a roaming session management network element in providing visited network service and session management for the at least one roaming user;

The data processing method of the embodiment of the invention is characterized in that a roaming user server is deployed at a roaming place and is used for carrying out centralized registration on the position of a local roaming user and carrying out unified query and distribution on the user subscription data and the service strategy of the roaming user, thus when the roaming user frequently changes a service network element at the roaming place where the roaming user server is deployed, the user subscription data of the roaming user does not need to be acquired from a home subscription data server, such as a home HLR or an HSS, of a home network to which the roaming user belongs for many times, the service strategy of the roaming user does not need to be acquired from the home strategy server of the home network to which the roaming user belongs for many times, and the purposes of providing visited network service for the roaming user and carrying out session management on the roaming user can be realized only by acquiring the user subscription data and the service strategy from the roaming user server, therefore, the method reduces the cost of roaming signaling, improves the session efficiency of the roaming user, and is suitable for the flow simplification target under the 5G network architecture.

In this embodiment, a specific process of the roamer server acquiring the user subscription data of the roamer from the home network of the roamer is as follows:

the roaming user server receives a position updating request corresponding to the target user equipment, which is sent by the roaming service network element when the target user equipment is determined to be a roaming user; the location updating request is generated by the roaming service network element according to the received mobility-related request message sent by the target user equipment; here, the roaming service network element may specifically be a visited service network element of a roaming place where the target device is currently located, for example, an MME, an MSC, and an SGSN. The mobility-related request message may particularly characterize a location update or a location registration.

Further, when the mobility-related request message corresponding to the location update request represents location update or location registration, the roaming subscriber server determines whether user subscription data and first location information corresponding to the target user equipment are stored in the roaming subscriber server according to the location update request; and further processing the user subscription data and the first position information corresponding to the target user equipment according to the judgment result.

Specifically, in a specific embodiment, when the determination result indicates that the user subscription data and the first location information corresponding to the target user equipment are stored, the roaming subscriber server obtains current first location information of the target user equipment from a received location update request sent by the roaming service network element, and updates the stored first location information corresponding to the target user equipment when determining that the current first location information is different from the stored first location information; here, since the roaming service network element sends a location update request to the roaming user server, that is, the location of the target user equipment in the roaming network changes, so that the roaming service network element visited by the target user equipment in the roaming network changes, the first location information stored in the roaming user server, that is, the first location information of the visited roaming service network element before the location of the target user equipment changes, is obviously different from the first location information of the currently visited roaming service network element, and therefore, in practical applications, the current first location information acquired by the roaming user server is necessarily different from the stored first location information.

Further, the roaming user server obtains user subscription data corresponding to the target user equipment from user subscription data stored in the roaming user server, and sends the user subscription data corresponding to the target user equipment to the currently visited roaming service network element according to the updated first location information corresponding to the target user equipment, that is, the first location information of the currently visited roaming service network element of the target user equipment, so that the currently visited roaming service network element provides a visited place network service for the target user equipment through the user subscription data corresponding to the target user equipment. That is to say, in practical application, when the location of the target user equipment in the roaming network changes, that is, the roaming service network element visited by the target user equipment in the roaming network changes, at this time, the roaming service network element currently visited by the target user equipment only needs to acquire the user subscription data corresponding to the target user equipment from the roaming user server, and can provide the visited network service for the target user equipment.

In another embodiment, when the determination result indicates that the user subscription data corresponding to the target ue is not stored, the roamer server obtains the user subscription data corresponding to the target ue from a home subscription data server in a home network of the target ue, stores the user subscription data corresponding to the target ue, and informs a home subscription data server of the target ue of an address of the roamer server;

the roaming user server acquires the current first position information of the target user equipment from the received position updating request sent by the roaming service network element, and records the current first position information of the target user equipment; and then according to the current first position information of the target user equipment, sending the stored user subscription data corresponding to the target user equipment to a roaming service network element, so that the roaming service network element provides the visited network service for the target user equipment through the user subscription data corresponding to the target user equipment.

Here, the home subscription data server may specifically be an HLR or an HSS to which the target user equipment belongs, that is, the HLR or the HSS of the home network of the target user equipment.

In another specific embodiment, the roaming subscriber server receives a registration deletion request corresponding to the target user equipment, which is sent by the roaming service network element when the target user equipment is determined to be a roaming subscriber; the registration deletion request is generated by the roaming service network element according to the received detach message sent by the target user equipment; and the roaming user server deletes the user subscription data and the first position information corresponding to the target user equipment according to the registration deletion request.

In this embodiment, the specific process of the roaming user server obtaining the service policy of the roaming user from the home network of the roaming user is as follows:

the roaming user server receives a session management request corresponding to the target user equipment, which is sent by a roaming session management network element when the target user equipment is determined to be a roaming user; the session management request is generated by the roaming session management network element according to the detected session state related information corresponding to the target user equipment; here, the roaming session management network element may specifically be a service network element capable of providing a service policy in a roaming location where the target user equipment is located, that is, a service network element capable of providing a service policy in a roaming network where the target user equipment is currently accessed, for example, a PCEF; the session state related information may particularly characterize a session establishment, a session change or a session deletion.

Further, in a specific embodiment, when the session state related information corresponding to the session management request represents session establishment or session change, the roaming user server determines, according to the session management request, whether a service policy and second location information corresponding to the target user equipment are stored in the roaming user server;

and processing the service strategy and the second position information corresponding to the target user equipment according to the judgment result.

Specifically, when the judgment result represents that the service policy and the second location information corresponding to the target user equipment are stored, the roaming user server obtains the current second location information of the target user equipment from the received session management request sent by the roaming session management network element, and updates the stored second location information corresponding to the target user equipment when determining that the current second location information is different from the stored second location information; here, since the roaming session management network element sends the session management request to the roamer server, that is, the location of the target ue in the roaming network changes, so that the roaming session management network element accessed by the target ue in the roaming network changes, the second location information stored in the roamer server, that is, the second location information of the roaming session management network element accessed before the location of the target ue changes, is obviously different from the second location information of the currently accessed roaming session management network element, and therefore, in actual application, the current second location information acquired by the roamer server is inevitably different from the stored second location information.

Further, a service policy corresponding to the target user equipment is acquired from the service policies stored in the roaming session management network element, and the service policy corresponding to the target user equipment is sent to the roaming session management network element according to the updated second location information, so that the roaming session management network element performs session management on the target user equipment through the service policy corresponding to the target user equipment. That is to say, in practical application, when the position of the target user equipment in the roaming network changes, that is, the roaming session management network element accessed by the target user equipment in the roaming network changes, at this time, the roaming session management network element currently accessed by the target user equipment only needs to acquire the service policy corresponding to the target user equipment from the roaming user server, and then session management can be performed on the target user equipment.

Further, when the determination result indicates that the service policy and the second location information corresponding to the target ue are not stored, the roamer server obtains the service policy corresponding to the target ue from a home policy server in a home network of the target ue, stores the service policy corresponding to the target ue, and informs the home policy server of the target ue of the address of the roamer server;

and sending the stored service strategy corresponding to the target user equipment to a roaming session management network element according to the current second position information of the target user equipment, so that the roaming session management network element performs session management on the target user equipment through the service strategy corresponding to the target user equipment.

In another specific embodiment, the roaming subscriber server receives a session management request corresponding to the target user equipment, which is sent by the roaming session management network element when the target user equipment is determined to be a roaming subscriber; the session management request is generated by the roaming session management network element according to the detected session state related information corresponding to the target user equipment;

and when the session state related information corresponding to the session management request represents session deletion, the roaming user server deletes the service policy and the second position information corresponding to the target user equipment according to the session management request. Here, the home policy server may specifically be a PCRF of a home network to which the target user equipment belongs.

In practical application, when the user subscription data of a roaming user changes, the roaming user server also needs to synchronize the updated user subscription data; in particular, the amount of the solvent to be used,

the roaming user server receives a user subscription data modification request sent by a home subscription data server corresponding to a first roaming user in the at least one roaming user when the user subscription data corresponding to the first roaming user is determined to be changed; updating the user subscription data corresponding to the first roaming user according to the user subscription data modification request; the roaming user server acquires first position information of the first roaming user recorded by the roaming user server; and sending the updated user subscription data corresponding to the first roaming user to a current roaming service network element of the first roaming user according to the first position information of the first roaming user recorded by the user subscription data synchronization device, so as to synchronize the user subscription data.

Similarly, when the service policy of the roaming user changes, the roaming user server also needs to synchronize the updated service policy; in particular, the amount of the solvent to be used,

the roaming user server receives a service policy modification request which is stored by the roaming user server and sent by an attribution policy server corresponding to a second roaming user in the at least one roaming user when the service policy is determined to be changed; updating the service policy corresponding to the second roaming user according to the request for modifying the service policy; the roaming user server acquires second position information of the second roaming user recorded by the roaming user server; and sending the updated service policy corresponding to the second roaming user to a current roaming session management network element of the second roaming user according to the second position information of the second roaming user recorded by the self so as to synchronize the service policy.

In practical application, when a roaming user serves as a short message receiving party, a network needs to inquire the position registered by the roaming user, so that the method provided by the embodiment of the invention can change a short message receiving scene; in particular, the amount of the solvent to be used,

the roaming user server receives a short message issuing message sent by a short message service center; the short message issuing message represents a request message of sending the short message to a third roaming user in the at least one roaming user by the short message service center; here, the first location information of the third roaming subscriber has been stored in the roaming subscriber server; further, the roaming subscriber server acquires the first location information of the third roaming subscriber according to the information corresponding to the third roaming subscriber as the called subscriber in the received short message issuing message, modifies the destination address in the short message issuing message into the first location information of the third roaming subscriber, and sends the short message issuing message to the current roaming service network element of the third roaming subscriber according to the first location information of the third roaming subscriber, so as to issue the short message corresponding to the short message issuing message through the roaming service network element.

In practical application, when a roaming user is used as a called user, a network needs to inquire the position registered by the roaming user, so the method of the embodiment of the invention can change the called flow; in particular, the amount of the solvent to be used,

the roaming user server receives routing query information; the route query information represents route query information which is generated according to route request information of a calling party and sent by a home subscription data server to which a fourth roaming user belongs in the at least one roaming user; here, the first location information of the fourth roaming subscriber has been stored in the roaming subscriber server; further, the roaming user server obtains first location information corresponding to the fourth roaming user according to the routing query information, obtains target routing information from a roaming service network element currently visited by the fourth roaming user according to the first location information corresponding to the fourth roaming user, and sends the target routing information to an attribution subscription data server to which the fourth roaming user belongs, so that the calling user and the roaming service network element of the fourth roaming user establish a call through the target routing information.
