The form that software (including firmware, resident software, microcode etc.) or hardware and software combine.
Embodiment according to the present invention proposes a kind of method and dress for selecting mobility management mechanism for terminal on demand
It sets.
First embodiment
In embodiments of the present invention, the user information that operator can be obtained by its Operation Support System, terminal letter
The business information that breath, business network or third-party application provide, the traffic model etc. of user excavate the user in its network
The mobility model (or rule) of terminal, the feature of mobile application.The above- mentioned information of acquisition are then based on, can determine its network
It is middle need to mobility support grade to be offered, such as it is high, in or inferior grade mobility support.
Correspondingly, the network management system of operator divides its network according to required mobility support grade, such as
Network slice is carried out, so that heterogeneous networks realize different grades of mobility support.But it can be able to achieve in a network multiple etc.
The mobility support of grade.
When terminal accesses the carrier network, the mobility support rank decision-making function in network (is alternatively referred to as moved
Property support level decision-making function entity), such as mobility grade determines that (alternatively referred to as mobility grade determines function reality to function
Body), first according to the access request of terminal, such as attach request, position updating request connects and establishes request etc., determines the end
Mobility support rank needed for end.According to mobility support rank needed for determining terminal, network selection functional (can also claim
For network selection functional entity) it is the network that terminal selection is capable of providing required mobility support.
Referring to Fig. 1, a kind of method for selecting mobility management mechanism on demand for terminal, the execution of this method are shown in figure
Main body can be mobility support rank decision-making function (alternatively referred to as mobility grade determines function), the specific steps are as follows:
Step S110, mobility support rank needed for determining terminal；
The definition that code-on-demand migration supports concept is proposed in 3GPP TR 23.799, i.e., network is based on terminal and business
Different characteristics provide different mobility supports, and the concrete function of above-mentioned mobility support may include following any one or more
: it is mobility context management, position tracking (location updating), paging, switching control, path optimization's (anchor point gravity treatment), reachable
Property management, is also not limited to this certainly.

Dynamic property is supported and the mobility support of inferior grade, and the priority based on terminal or business carries out grade to mobility support rank and draws
Point, or the progress grade classification of the concrete function based on mobility support grade, it is of course possible to understanding, in the present embodiment simultaneously
The specific grade division mode of mobility support rank is not limited.
In step s 110, can be according to end message and/or the type of service of terminal request, shifting needed for determining terminal
Dynamic property support level.
In the present embodiment, when condition any one or more below meeting, movement needed for determining terminal is triggered
Property support level, actual conditions are as follows:
When terminal is attached to network, mobility support rank needed for determining terminal；
When terminal carries out location updating, mobility support rank needed for determining terminal；And/or

In the present embodiment, before above-mentioned steps S110, mobility support rank decision-making function can receive network selection
The request of mobility support rank needed for function determines terminal.Mobility support rank is triggered by network selection functional to sentence
Determine mobility support rank needed for function determines terminal, is also not limited to this certainly.
Step S120, the mobility support rank according to needed for determining terminal, notice network selection functional selection can
The network or network function of mobility support rank needed for supporting, to provide the terminal with corresponding mobile management.
The network or network function of mobility support rank needed for above-mentioned support include following any one: being moved needed for supporting
One group mobility management function of mobility support rank needed for the network slice of dynamic property support level and support (is alternatively referred to as moved
Mobility management functional entity), it is also not limited to this certainly.
Above-mentioned network slice or mobile management function to ps domain can be generated according to the mobility rank needed support in network.
In the present embodiment, judge whether the mobile management function to ps domain of current service terminal can provide the terminal with the end
Mobility support needed for end；If can not, mobility support rank needed for the terminal carries out the choosing of mobile management function to ps domain
It selects.
In the present embodiment, judge terminal access network whether can provide the terminal with terminal needed for mobility branch
It holds；If can, provide the terminal with corresponding mobile management；If can not, carry out the gravity treatment of target network.
It should be noted that in the present embodiment, carrying out the gravity treatment of target network in the following manner:

Business information, the traffic model etc. of user excavate the mobility model (or rule) of the user terminal in its network, mobile application
Feature.Information based on acquisition, determining needs mobility support grade to be offered in its network, such as high, in, inferior grade
Mobility support, and be stored in the signing attribute of terminal user.As shown in Fig. 2, the mobile description system of operator deployment carries out
The discovery of terminal mobility model and the description of mobile service, so that it is determined that needing to provide mobility support in network.
Based on the decision of mobile description system, the operation management layer of carrier network can determine whether how to provide required movement
Property support.If the network slice manager judgement of operation management layer needs to create new network slice, network is sliced manager
Network slice description system need to be requested to carry out the description of network slice to be established.Network slice description system is for defining wait establish
The all-network function of network and interconnection.In order to provide the mobility management mechanism that can satisfy mobility support demand,
System can increase mobile management function to ps domain body description (MMF description, mobility management
Functionality description) function carries out the specific definitions of all mobile management sub-functionalities, assist network
It is sliced the definition that representation function carries out network slice.After network slice representation function completes slice description, notice network slice
Manager triggers the generation of network slice.In specific implementation, operator or MMF function may be defined as follows the mobility of type
Administrative mechanism:
1. control planar movement management function and user plane mobility anchor concentration are deployed in core net, session is supported
