Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for selecting a mobility management mechanism for a terminal as needed.

Background technique

According to the description of 3GPP TR 22.891, future 5G networks need to provide mobility support with different requirements. Because there are different communication scenarios in 5G networks: different terminals have different mobile paradigms, for example, some terminals access the network in high-speed mobile, while others are nomadic access networks or static access networks; different services It also has different mobility support requirements. For example, some services want to reduce the interruption and packet loss rate in the service transmission process. Therefore, the network is required to shield the application layer from mobility events, including keeping the IP address unchanged during the handover process. Some applications can use application layer means to support business continuity. Based on these considerations, 3GPP proposes on-demand mobility support.

At present, SA2 proposes a method for on-demand mobility management (3GPP TR 23.799), which specifically requires a mobility management control function in the network, which can acquire the mobility level of the terminal based on information such as subscription of the terminal. Based on the mobility level of the terminal, the mobility management control function configures the mobility management sub-function in the network, activates the mobility management sub-function that needs to provide services to the terminal, thereby providing a tailor-made mobility management mechanism for the terminal.

The existing solution for on-demand mobility support requires all mobility management sub-functions in the network to increase the complexity of the network. The mobility management control function in the network needs to determine which mobility managers are activated according to the mobility support level.

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

Those skilled in the art will appreciate that embodiments of the present disclosure may be implemented as a system, apparatus, device, method, or computer program product. Thus, embodiments of the present disclosure may be embodied in the form of full hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

According to an embodiment of the present disclosure, a method and apparatus for selecting a mobility management mechanism for a terminal as needed are proposed.

In some embodiments of the present disclosure, the operator may mine the user terminal in the network through the user information acquired by the operation support system, the terminal information, the service information provided by the service network or the third party application, the communication model of the user, and the like. Mobility model (or regularity), characteristics of mobile applications. Then based on the obtained information obtained, it is possible to determine the mobility support level that needs to be provided in the network, such as high, medium or low level mobility support.

Correspondingly, the operator's network management system divides its network according to the required mobility support level, for example, network slicing, so that different networks implement different levels of mobility support. However, multiple levels of mobility support may be implemented in a network.

When the terminal accesses the carrier network, a mobility support level determining function (also referred to as a mobility support level determining function entity) in the network, such as a mobility level determining function (also referred to as a mobility level determining function entity) First, the mobility support level required by the terminal is determined according to an access request of the terminal, such as an attach request, a location update request, a connection establishment request, and the like. Based on the determined level of mobility support required by the terminal, a network selection function (also referred to as a network selection function entity) selects a network for the terminal that can provide the required mobility support.

Referring to FIG. 1, a method for selecting a mobility management mechanism for a terminal on demand is shown, and an execution body of the method may be a mobility support level determination function (also referred to as mobility level determination). Function), including the following steps.

Step S110, determining a mobility support level required by the terminal;

The definition of on-demand mobility support concept is proposed in 3GPP TR 23.799, that is, the network provides different mobility support based on different characteristics of terminals and services. The specific functions of the above mobility support may include any one or more of the following: mobility Context management, location tracking (location update), paging, handover control, path optimization (anchor reselection), reachability management, and of course not limited to this.

In this embodiment, the mobility support level may be divided into high-level mobility support, medium-level mobility support, and low-level mobility support, and the mobility support level is classified based on the priority of the terminal or the service. Or, based on the specific function of the mobility support level, it is of course understood that the specific level division mode of the mobility support level is not limited in this embodiment.

In step S110, the mobility support level required by the terminal may be determined according to the terminal information and/or the service type requested by the terminal.

In this embodiment, when the condition of any one or more of the following conditions is met, the mobility support level required for determining the terminal is triggered, and the specific conditions are as follows: when the terminal is attached to the network, determine the mobility support level required by the terminal. Determining the mobility support level required by the terminal when the terminal performs location update; and/or determining the mobility support level required by the terminal when the terminal initiates the connection request.

In this embodiment, before the step S110 described above, the mobility support level determining function may receive a request for the network selection function to determine the mobility support level required by the terminal. That is, the mobility support level determination function is triggered by the network selection function to determine the mobility support level required by the terminal, and is of course not limited thereto.

Step S120: The network selection function is notified to select a network or network function capable of supporting a required mobility support level according to the determined mobility support level required by the terminal, to provide corresponding mobility management to the terminal.

The above network or network features that support the required mobility support level include any of the following: network slicing that supports the required mobility support level and a set of mobility management features that support the required mobility support level (also known as mobile The sexual management function entity) is of course not limited to this.

The network slicing or mobility management functions described above can be generated based on the level of mobility that needs to be supported in the network.

In this embodiment, it is determined whether the mobility management function of the current serving terminal can provide the terminal with the mobility support required by the terminal; if not, the terminal needs the mobility support level to perform the mobility management function selection. .

In this embodiment, it is determined whether the network accessed by the terminal can provide the terminal with mobility support required by the terminal; if so, the terminal is provided with corresponding mobility management; if not, the target network is reselected.

It should be noted that, in this embodiment, the reselection of the target network is performed by:

Method 1: Send a request message to the network selection function, and the network selection function reselects the target network for the terminal, and the request message carries at least the mobility support level required by the terminal;

Manner 2: performing target network selection according to the required mobility support level of the terminal; determining an identifier of the target network capable of providing the required mobility support level, providing the identifier of the target network to the network selection function, and the network selection function according to the target network Identify the target network.

In this embodiment, first determining a mobility support level required by the terminal, and then notifying the network selection function to select a network or network function capable of supporting the required mobility support level according to the determined mobility support level required by the terminal, Provide corresponding mobility management to terminals, simplifying the composition of different networks by implementing different levels of mobility support in different networks; and avoiding complex network function configuration for different mobility support terminal services through different networks. , effectively reducing the complexity of mobility management.

Referring to FIG. 2, FIG. 2 is introduced to divide the carrier network into networks that implement different mobility support levels.

Specifically, the user information acquired by the operator, the terminal information, the service information provided by the service network or the third-party application, the communication model of the user, etc., excavate the mobility model (or law) of the user terminal in the network, and the mobile application Characteristics. Based on the acquired information, determine the mobility support level that needs to be provided in the network, such as high, medium, and low level mobility support, and save it in the subscription attribute of the end user. As shown in FIG. 2, the operator deploys a mobile description system to perform discovery of the terminal mobility model and description of the mobile service, thereby determining that mobility support needs to be provided in the network.

Based on the decision of the mobile description system, the operational management of the operator's network can determine how to provide the required mobility support. If the network slice manager of the operation management layer determines that a new network slice needs to be created, the network slice manager needs to request the network slice description system to perform a description of the network slice to be established. The network slice description system is used to define all network functions and interconnections of the network to be established. In order to provide a mobility management mechanism that can meet the mobility support requirements, the system can add a mobility management functionality description (MMF description, mobility management functionality description) function to perform detailed definition of all mobility management sub-functions, and assist network segmentation. Describe the function to define the network slice. After the network slice description function completes the slice description, the network slice manager is notified to trigger the generation of the network slice. In a specific implementation, the operator or MMF function may define the following types of mobility management mechanisms:

1. The control plane mobility management function and the user plane mobility anchor point are centrally deployed in the core network to support session continuity;

2. The control plane mobility management function and the user plane mobility anchor point are centrally deployed in the core network, and session continuity is not supported;

3. The control plane mobility management function is deployed centrally on the core network, and the user plane mobility anchor point is deployed close to the user location to support session continuity;

4. The control plane mobility management function is deployed centrally on the core network. The user plane mobility anchor is deployed close to the user location and does not support session continuity.

5. The control plane mobility management function is deployed on the access network side, and the user plane mobility anchor point deploys the core network to support session continuity;

6. The control plane mobility management function is deployed on the access network side, and the user plane mobility anchor point is deployed close to the user location to support session continuity;

7. The control plane mobility management function is deployed on the access network side, and the user plane mobility anchor point is deployed close to the user location, and session continuity is not supported.

The specific mobility management function is shown in Figure 2. It may include: mobility context management Mobility context management; location tracking Location tracking; paging paging; handover control Handover control; path optimization Path optimization; Reachability mangement.

The network slice manager requests the orchestration control layer to perform specific generation of the network slice, for example, requesting the MANO (Management and Orchestration) system to generate a specific network slice. After the network slice is generated, the network slice manager is also responsible for managing its life cycle, such as modifying or revoking the network slice.

The network slicing framework enables the network to generate network slices that support different mobility levels, such that terminals with different mobility requirements may be served by different network slices, for example, when receiving a small data transmission request from a static smart meter device, Selecting the control plane mobility management function and the user plane mobility anchor point for the terminal to be deployed centrally on the core network, the network that does not support the session continuity, does not need to support location tracking; when receiving the IMS call service initiated by the SMART phone (smart phone) When the terminal selects the control plane mobility management function and the user plane mobility anchor point is deployed centrally on the core network, the network supporting the session continuity does not need to support path optimization (the anchor point is unchanged).

In some embodiments, as shown in FIG. 3A and FIG. 3B, the mobility level determination function is implemented in each network. In specific implementation, the mobility level determination function is located in the corresponding network, see FIG. 3A; mobility level determination. Features may be shared by multiple networks, see Figure 3B. The purpose is to determine the mobility support level required by the current terminal according to the mobile information and service of the terminal after the terminal accesses the network, thereby selecting a network capable of providing a suitable mobility management mechanism or function for the terminal.

It should be noted that, in this embodiment, the terminal is attached to the network process, and the network selection function selects the target network according to the type of the terminal, signing, and the like.

Referring to FIG. 4, the process of initiating connection establishment or location update in a connected network is described in conjunction with FIG. 4, and the specific steps are as follows:

Step S401: The UE sends an access request, such as a location update request, a connection establishment request, and the like, in the attached network.

Step S402: After receiving the request from the terminal, the attached network determines the mobility support level currently required by the terminal by the mobility level determining function in the network, and determines whether the network can provide the required mobility support to the terminal. If so, provide corresponding mobility management to the terminal;

In step S403, it is determined that the attached network cannot provide the required mobility support to the terminal, and the mobility level determining function requests the network selection function to reselect the target network, and the request message carries at least the mobility support level required by the terminal. Or the mobility level determination function performs target network selection according to the required mobility support level, step S404 skips, and proceeds to step S405.

Step S404: The network selection function reselects the target network according to the received information, and responds.

Step S405, triggering and performing a handover or location update process to redirect the terminal to the target network.

In some embodiments, referring to FIG. 5, the network selection function is required according to the terminal. The mobility support level selects the target network. As shown in FIG. 5, the mobility level determination function is independent of each network. When the terminal accesses the network, requests location update or establishes a connection, the network selection function selects an appropriate target network according to the mobility level currently required by the terminal. It is of course understood that the mobility level determination function may be set to a functional entity with the network selection function.

It should be noted that, in this embodiment, the terminal is attached to a network-related related technology, and the network selection function selects a target network according to the type of the terminal, signing, and the like.

Referring to FIG. 6, the process of initiating connection establishment or location update of a terminal is introduced. The specific steps are as follows:

Step S601: The network selection function is based on an access request of the terminal, such as a connection establishment request, a location update request, and the like;

Step S602: The network selection function requests the mobility level determining function to determine a mobility support level required by the terminal;

Step S603: The mobility level determining function determines, according to the terminal information, for example, the terminal type, the terminal location, and/or the service type requested by the terminal, the mobility support level currently required by the terminal, and returns;

Step S604: The network selection function selects, according to the mobility support level required by the terminal for the access, the target network that can provide the required mobility support.

Step S605: If the target network is a network to which the terminal is attached, send an access request to the attached network, otherwise trigger and perform a handover or location update process to redirect the terminal to the target network.
