Strategy, customer service continuity strategy, user plane selection strategy etc..
The Mobility Management Strategy is including but not limited to mobile and connection status administrative mechanism, mobility grade, movement
Property restricted area etc..
Control module performs the request, storage and execution work(of network dicing strategy as network dicing strategy execution module
Can, mainly include：Judge whether a certain cut into slices supports the policy control ability of slice-level (to judge whether to support dicing strategy control
Condition processed)；(advised using network section as granularity to policy module application and the management of request user conversation, mobile management etc. are tactful
Then)；Receive and store the strategies (rule) such as the corresponding user conversation management of each section, mobile management；For in network section
Corresponding user performs corresponding control (rule).
The generation module for the dicing strategy that policy module is cut into slices as network, generates network according to the business demand of section and cuts
The strategy such as the corresponding session management of piece, mobile management (rule), and be handed down to control module and performed.
The policy module, mainly includes：The business demand or network performance demand cut into slices according to network, according to certain
Strategy and algorithm, generate the strategies such as the corresponding user conversation management of each network section, mobile management；Receive control module
Strategy application request, distributing policy；The corresponding network Control architecture information of each network section is recorded, is issued with guarantee strategies
Validity etc..
Note：This example is suitable for the business applied field that user and business demand are consistent under the same conditions in section
Scape, therefore the scheme provided in this example proposes：Judge whether a certain network section is applicable in by control module and be based on dicing strategy control
Condition processed.
Example two：
As shown in fig. 6, this example provides a kind of policy control method, it may include：
Step 1：First user reaches the standard grade, i.e., user equipment is connected to network；
Step 2：Control module detects new network section, judges that network section is if new network section is detected
No support dicing strategy control condition.
Step 3：Cut into slices when the network and support dicing strategy control condition, send dicing strategy request, carry map network
Section mark (Identity, ID).
Step 4：The corresponding control module information of policy module record network section, the corresponding session control of generation network section
Make the section plan such as (Session Management, SM) strategy and mobile control (Mobility Management, MM) strategy
Slightly.
Step 5：Issue and cut the dicing strategies such as SM strategies, MM strategies.
Step 6：Dicing strategy is stored, and the subscriber policy of the first user is generated according to dicing strategy.
Step 7：Second user is reached the standard grade；
Step 8：Judge whether the network used section has been stored dicing strategy by second user, if having stored generation second
The subscriber policy of user.
Step 9：The end-to-end subscriber policy for performing response.
Example three：
It is as follows that this example provides a kind of dicing strategy foundation request based on network section：
During new user access network (during such as new user plane session establishment), control module perceives new network section and connects
Enter into network, control module inquires about whether the section supports the tactical management work(based on section according to configured list or signing
Energy.Configured list includes section mark ID；Section positioned at configured list is identified as the strategy pipe whether supported based on section
The mark of the network section of reason.
If the tactical management based on section is supported in network section, control module is initiated to cut based on network to policy module
The strategy session of piece establishes request, and section ID, control module information etc. are carried in request.
Policy module is received after strategy session establishes solicited message, using the ID that cuts into slices as the corresponding meeting of the index search section
Management strategy and Mobility Management Strategy (such as conversation continuity, routing policy, QoS/ chargings, mobility grade strategy) are talked about,
Store and record the corresponding control module information of section ID at the same time.
Policy module replys strategy session and establishes response, and issues the corresponding session management of the section and shifting to control module
Mobility management strategy (such as conversation continuity, routing policy, QoS/ chargings, mobility grade strategy).
Control module receives strategy session management and Mobility Management Strategy information (such as session company that policy module issues
Continuous property, routing policy, QoS/ chargings, mobility grade strategy etc.) after, record and store the corresponding session managements of section ID and
Mobility Management Strategy information (such as conversation continuity, routing policy, QoS/ chargings, mobility grade strategy).
When section ID has new user to reach the standard grade or when new connection is established (such as UE initiates new session establishment flow),
Control module no longer removes request strategy, but is directly performed according to the stored corresponding policy information of section corresponding dynamic
Make, such as perform corresponding QoS mechanism, the corresponding movement of generation and session state transfer mechanism.
Example four：
As shown in fig. 7, this example provides a kind of policy control method, it may include：
Step 11：The information that policy module receives third party's request or signing information causes chip property to change；
Step 12：According to new business demand, dicing strategy is updated.
Step 13：Dicing strategy renewal request is initiated, carries the SM plans of the corresponding network sections of section ID and section ID
The dicing strategies such as summary, MM strategies.
Step 14：The dicing strategy of the corresponding network sections of the section ID is updated, generates new subscriber policy；Inquiry is worked as
Preceding online user account；
Step 15：The subscriber policies such as end-to-end renewal current online SM, MM of user account.
Step 16：New user reaches the standard grade：
Step 17：Judge whether the new user has existing network section user, generate the new user's according to storage strategy
Subscriber policy；
Step 18：It is end-to-end to perform corresponding subscriber policy.
Example five：
The detailed process that this example provides the strategy modification control based on network section is described below：
Because third party's request or service contracting modification cause network section network performance or quality of service to change, network is carried
The section mark and required network performance or quality of service requirements of section.
Policy module is calculated according to the section network performance demand received with reference to current network load state etc. according to conversion
Method, decomposition conversion is carried out by the overall network performance that network is cut into slices, and changes into the session management of single user and shifting in network section
Mobility management policy information (such as conversation continuity, routing policy, QoS/ chargings, mobility grade strategy).
Using network section as granularity, policy module judges the single user changed according to newest section network performance demand
Whether the grade of service is identical with the strategy being carrying out, and is exited if identical；If it is different, then corresponding to policy module to the section
The renewal request of control module distributing policy, network is carried in request and is cut into slices corresponding session management and Mobility Management Strategy letter
Cease (such as conversation continuity, routing policy, QoS/ chargings, mobility grade strategy) and corresponding network section ID.
Control module receives the session management that policy module issues and Mobility Management Strategy information, and (such as session is continuous
Property, routing policy, QoS/ chargings, mobility grade strategy etc.) after, renewal has stored the corresponding strategies of section ID.
Control module searches current online user and user conversation connection based on section ID, according to strategy is locally configured,
Initiate the end-to-end policy update flow of user in the section (qos parameter renewal, mobility grade renewal etc. can be included).
To new reach the standard grade user or session (the session establishment flow that such as UE is initiated, or attachment flow), perform after updating
Qos policy, mobility grade strategy etc..
The technical solution that above example provides, carries out the mechanism of policy control, in strategy based on the concept of network section
During control only when thering is new section to establish or corresponding strategy of cutting into slices has renewal, just generation policy module and control module it
Between tactful interaction flow, otherwise directly cut into slices corresponding user QoS, charging using network of its ownership when new user accesses
Deng strategy, without initiating new strategy interaction flow.The interaction flow between policy module and control module is simplified, also makes system
