Description

Address information processing method and device and functional entity

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an address information processing method, an address information processing apparatus, and a functional entity.

Background

With the increasing of mobile network users and the increasing diversification of user requirements, in order to ensure the information security of users and to manage the user behaviors more specifically, corresponding IP addresses can be allocated in corresponding address pools according to different attributes of the users when the users surf the internet, so that the user surfing behaviors can be controlled and traced more effectively, and the range of other users affected is reduced.

Specifically, IP address subdivision can be realized in a 4G existing network according to the location of a user, and GGSN (gateway GPRS (general packet radio service) support node), a converged GGSN, and SAE GW (system architecture evolution gateway) devices can allocate an IP address to the user from a corresponding IP address pool according to LAC (location area number) and TAC (tracking area number) information of the user, that is: each GGSN, the converged GGSN and the SAE GW device carries out address pool segmentation, each section of address pool corresponds to a smaller physical area, such as a district or a county (for example, one section of address pool corresponds to one district or county), but not one GGSN, the converged GGSN and the SAE GW device correspond to a whole province, and rapid user positioning is realized.

However, in order to ensure that the location of the user strictly corresponds to the address pool where its IP address is located, in the 4G network, by configuring a relevant offline policy on an MME (mobility management entity), the user can be forced to be offline and a new IP address can be reallocated when the user moves across regions.

In order to implement different cross-region offline strategies for different users, different APNs (access network names) and different regions, complex strategy configuration needs to be performed on an MME (mobility management entity), which may cause a great increase in the amount of strategy configuration, and once the cross-region offline strategies change, the change period is too long, which affects the service online time and user experience.

From the above, the existing address information processing scheme has the defects of high complexity and long period.

The address information processing method provided in the embodiment of the present invention is further described below with reference to multiple sides, such as a first functional entity, a second functional entity, and a third functional entity, where the first functional entity takes a user address management function UAMF entity (a special management function AF entity) as an example, the second functional entity takes a session management function SMF entity as an example, and the third functional entity takes an access and mobility management function AMF entity as an example.

In view of the above technical problems, embodiments of the present invention provide an address information processing method, so that UAMF can actively add, delete, and modify an address management policy and a user address of a user to an SMF. In addition, if the address management policies of multiple users are the same, the UAMF may also merge the address management policies of multiple users and issue them to the SMF through one message, so as to reduce the waste of signaling.

Specifically, the invention provides a 5G-based user policy management scheme, so that a special network element on a network side can manage and update the address of the user more effectively.

The scheme mainly provides a related address reallocation scheme aiming at the following points:

consider that: in order to implement different cross-region offline strategies for different users, different regions and different services, complex strategy configuration needs to be performed on the MME, which may cause a great increase in the amount of strategy configuration, and once the cross-region offline strategies change, the change period is too long, which affects the service online time and user experience.

For example, in some cases: firstly, performing cross-region offline on voice service on an access network 1 (such as an IP multimedia subsystem IMS), and performing cross-region offline on data service on an access network 2 (such as a CMNET); executing cross-regional offline for 1-5 counties and executing cross-regional offline for 6-9 counties; and executing cross-region offline for the user group A and executing cross-region offline for the user group B. The three-dimensional policy configuration requires configuring and modifying the MME in the country or province one by one, which is a huge workload.

Therefore, the embodiment of the present invention provides a solution, which may deliver the above-mentioned tedious Address Management task to a special AF (Application Function) to implement a related Function, such as a UAMF (user Address Management Function), so as to reduce the complicated configuration policy on each network element of the whole network when implementing different policies. The scheme mainly relates to UAMF which can realize the active addition, deletion and modification of the user address management strategy and the user address to the SMF.

(1) Part 1: the UAMF may implement active addition, deletion, and modification of user address and address management policies for the SMF.

Considering that when an address management policy of a user changes and needs to be updated urgently, for example, it is found that a network hacker is performing DoS or DDoS attack, some special users need to be managed and controlled urgently, and UAMF needs to issue related address management and change policies to SMF urgently, so that there is a need that UAMF actively adds, deletes, and modifies the address management policy and user address of the user to the SMF.

The present solution will be described below by way of example, but the present solution includes, but is not limited to, the following implementations.

(2) Part 2: for the same group of users (such as same number segment or DNN) in the same service and the same area, if the adopted strategies are completely the same, a message can be sent to the SMF by combining the UAMF, and the SMF adds, modifies and deletes the address management strategy according to the user group.

<1> implementation of the solution in this section can be based on the networking architecture shown in fig. 8, where UDM represents unified data management; UAMF indicates a user address management function; AMF denotes access and mobility management functions; SMF denotes a session management function; PCF denotes policy control function; UPF represents user plane functionality; DN denotes a data network; 5GC represents a 5G core network.

(3) Part 3: when the UAMF informs the SMF to add, modify and delete the address management strategy according to the user group, the UAMF, the SMF or the AMF can realize that users in the group are off-line in batches randomly, thereby avoiding sudden congestion caused by simultaneous on-line and off-line of a large number of users in an area. The specific implementation mode is as follows:

and <1> when the UAMF adds, modifies and deletes the users in the user group, the UAMF issues instructions for adding, deleting and modifying the address management strategies of the users to the SMF one by one, wherein the instructions comprise a random offline waiting time specified by the UAMF, and sudden congestion caused by simultaneous online and offline of a large number of users in an area is avoided. See section 1 for details of the definition of Offline Waiting Timer.

Specifically, it may be: the UAMF issues a processing instruction (deletion, update and/or addition) aiming at one or a group of users to the SMF, wherein the instruction carries a strategy ID (identity) and an offline waiting timer (optional) which need to be processed; if the group is a group, the group also comprises parameter identification used for grouping; so that the SMF, AMF operate on a set of users.

The random offline waiting time may be a time point or a time period, and then a time point is determined from the time period by the AMF.

And 2, when the SMF receives an instruction of adding, modifying and deleting an address management strategy to the user group by the UAMF, the SMF carries out offline in batches on the users in the group, thereby avoiding sudden congestion caused by simultaneous online and offline of a large number of users in an area to a network.

And <3> when the AMF receives the command of adding, modifying and deleting the address management strategy to the user group by the UAMF forwarded by the SMF, the AMF carries out batch offline on the users in the group, thereby avoiding sudden congestion caused by simultaneous online and offline of a large number of users in an area.

As can be seen from the above, the solution provided by the embodiment of the present invention involves:

(1) in a 5G core network, adding and defining a mechanism or a message of UAMF (universal asynchronous receiver/transmitter) to actively push an adding, modifying and deleting user address management strategy to an SMF (simple message forwarding); specifically, the method comprises the following steps:

the UAMF sends a request for subscriber address management to the SMF, which includes the type of subscriber address management and the IP address assigned to the subscriber (add, modify). After receiving the request, the SMF sends a response to the UAMF.

(2) For the same group of users (such as number segments) in the same service and the same area, if the adopted strategies are completely the same, a message can be sent to the SMF by combining the UAMF, and the SMF adds, modifies and deletes the address management strategy according to the user groups;

that is, the sent request carries a group identifier, and the SMF issues the IP address in units of groups according to the group identifier after receiving the request.

(3) When the UAMF informs the SMF to add, modify and delete the address management strategy according to the user group, the UAMF, the SMF and the AMF can realize that users in the group are off-line in batches randomly, thereby avoiding sudden congestion caused by simultaneous on-line and off-line of a large number of users in an area.

In summary, compared with the prior art, the present solution utilizes a special user Address to manage uamf (ue Address Management function) so as to manage, allocate, and update the IP Address conveniently: using an addition definition UAMF to actively push a mechanism or a message for adding, modifying and deleting a user address management strategy to the SMF in a 5G core network (part 1); for the same group of users (such as number segments) in the same service and the same area, if the adopted strategies are completely the same, a message can be sent to the SMF by combining the UAMF, and the SMF adds, modifies and deletes the address management strategy according to the user group (part 2); when UAMF informs SMF to add, modify and delete address management strategy according to user group, UAMF, SMF and AMF can implement random batch off-line of users in group, so as to avoid sudden congestion of network caused by simultaneous on-off line of a large number of users in one area (part 3).

Likewise, operational data may be identified within the modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.

When a module can be implemented by software, considering the level of existing hardware technology, a module implemented by software may build a corresponding hardware circuit to implement a corresponding function, without considering cost, and the hardware circuit may include a conventional Very Large Scale Integration (VLSI) circuit or a gate array and an existing semiconductor such as a logic chip, a transistor, or other discrete components.
