Specific embodiment
Below in conjunction with the attached drawing in the application, the technical solution in the application is described.In embodiment of the method Concrete operation method also can be applied in Installation practice or system embodiment.Wherein, in the description of the present application, unless separately It is described, the meaning of " plurality " is two or more.
Framework and business scenario described herein are the technical solutions in order to more clearly illustrate the application, not Constitute restriction for technical solution provided by the present application, those of ordinary skill in the art it is found that with the network architecture differentiation With the appearance of new business scene, technical solution provided by the present application is equally applicable for similar technical problem.
Currently, 5G net definitions LADN, and there are certain regions by LADN, only when terminal is in the overlay area of LADN It is interior, the service of LADN offer could be provided.
It is the registration area relation schematic diagram of LADN provided by the present application and terminal, the current Acceditation Area of terminal with reference to Fig. 1 Domain indicates that the overlay area of LADN is indicated with B with A, and the two has overlapping, and overlapping region is indicated with C, when terminal is in registration area A And not in overlapping region C, then terminal is not under the covering of LADN, at this point, LADN cannot provide service for terminal；Work as terminal When positioned at overlapping region C, terminal is under the covering of LADN, at this point, LADN can provide service for terminal.
As a kind of implementation, LADN be can be by tracking area list (tracking area list, TA List) structure At, each TA List includes one or more TA, and each TA is made of one or more cells, and using TA as minimum unit, It is made of that is, LADN can regard as one or more TA, for example, LADN B shown in FIG. 1 includes { TA1, TA2 }, wherein TA1 Including { cell 1, cell 2 }, TA2 includes { cell 3, cell 4 }.As another implementation, LADN be can be by TA List It constitutes, each TA List includes one or more TA, and each TA is made of one or more cells, and using cell as minimum Unit, either, LADN can be directly made of one or more cells, and cell is as minimum unit, for example, shown in FIG. 1 LADN B includes { cell 1, cell 2, cell 3, cell 4 }.
As a kind of implementation, registration area can be to be made of TA List, and each TA List includes one or more A TA, each TA are made of one or more cells, and using TA as minimum unit, that is, registration area can be regarded as by one Or multiple TA are constituted, and for example, registration area A shown in FIG. 1 includes { TA2, TA3 }, wherein TA2 includes { cell 3, cell 4 }, TA3 includes { cell 5 }.As another implementation, registration area can be to be made of TA List, and each TA List includes One or more TA, each TA are made of one or more cells, and using cell as minimum unit, either, registration area It can be directly made of one or more cells, cell is as minimum unit, for example, registration area A shown in FIG. 1 includes { small Area 3, cell 4, cell 5 }.
To, as a kind of implementation, when LADN and the registration area of terminal using TA as minimum unit when, then may be used Whether to include identical TA according to the registration area of LADN and terminal, to judge whether the two has overlapping region, for example, on It states in example, LADN B includes { TA1, TA2 }, and registration area A includes { TA2, TA3 }, therefore, the overlapping region of the two are as follows: TA2, when terminal is located at TA2, then LADN B can provide service for terminal, and when terminal is located at TA3, then LADN B cannot be Terminal provides service.
As another implementation, when LADN and the registration area of terminal using cell as minimum unit when, then may be used Whether to include identical cell according to the registration area of LADN and terminal, to judge whether the two has overlapping region, for example, In above-mentioned example, LADN B includes { cell 1, cell 2, cell 3, cell 4 }, and registration area A includes { cell 3, cell 4, cell 5 }, the overlapping region of the two are as follows: cell 3 and cell 4.Therefore, in conjunction with Fig. 1, when terminal is located at cell 3 or cell 4, then LADN B can provide service for terminal, and when terminal is located at cell 5, then LADN B cannot provide service for terminal.
For terminal when registration accesses network, the mobile management function to ps domain entity of core net can give terminal distribution registration area, Since the position of terminal can move, it is that terminal redistributes Acceditation Area that the movement of terminal, which may cause mobile management function to ps domain entity, Simultaneously it is handed down to terminal in domain.
It with reference to Fig. 2, is the registration area relation schematic diagram of another kind LADN and terminal provided by the present application, terminal is currently Registration area is registration area 1, and due to the movement of terminal, when terminal removes registration area 1, terminal can initiate register flow path, For example, when terminal is in position 1, the registration area of terminal is registration area 1, if terminal is moved to position 2, since terminal removes Registration area 1, terminal initiate register flow path, and mobile management function to ps domain entity is that terminal redistributes registration area 2.Compare again Such as, if terminal is moved to position 3 by position 1, mobile management function to ps domain entity is that terminal redistributes registration area 3.
In the figure 2 example, the registration area 1 Yu LADN of terminal have overlapping region, therefore, when terminal is located at registration When region 1 and the overlapping region of LADN, LADN can provide service for terminal.But if the registration area of terminal becomes Change, for example be updated to registration area 3, since registration area 3 and LADN do not have overlapping region, at this point, LADN cannot mention for terminal For service.
Further, for the terminal in Idle state, when terminal moves in registration area, network side does not perceive end Specific position is held, i.e. network side only knows the registration area where terminal, in this case it is not apparent that the specific cell where terminal.To scheme For 1, if registration area A includes { cell 3, cell 4, cell 5 }, when the terminal of Idle state moves in registration area A, than Such as be moved to cell 5 from cell 3, or be moved to cell 4 etc. from cell 3, network side only know terminal in registration area A, but It is not aware that terminal is in cell 3, in cell 4, or in cell 5.
Further, for the terminal in connected state, when terminal moves in registration area, then network side can be felt Know the specific position of terminal, that is, can determine that terminal in which cell.And the terminal for connected state, it can be between LADN One or more PDU session is established, and PDU session can there are many states, for example including activated state, deactivated state etc..
Currently, in long term evolution (long term evolution, LTE) network, when LADN has downlink data, under Row data arrive first at user plane functions entity, if user plane functions entity has available tunnel, show user plane functions entity It can be communicated by the PDU session of activation with the terminal of connected state, therefore can directly pass through PDU session, downlink data is sent out It send to terminal；If user plane functions entity does not have available tunnel, there are two types of situation, a kind of situation is that terminal is in connected state, But the corresponding PDU session of the downlink data is in deactivated state, at this time user plane functions entity can not by PDU session will under Row data are sent to terminal；Another situation is that terminal is in Idle state, i.e., all PDU sessions all in deactivated state, this When, downlink data also can not be sent to terminal by PDU session by user plane functions entity, regardless of situation, user face Functional entity can all send a notification message to conversation management functional entity, and announcement session management function entity has downlink data to arrive It reaches, after the notified message of conversation management functional entity, notifies mobile management function to ps domain entity call terminal, terminal receives shifting After the paging of mobility management functional entity, initiating business request process initiates the process for establishing PDU session, then terminal is logical Cross the downlink data that the PDU session established receives LADN.
Main problem existing for above-mentioned technical proposal is: the registration area that terminal is currently located is possible to not weigh with LADN It is folded, cause LADN that cannot provide service for terminal, therefore, even if mobile management function to ps domain entity call terminal, terminal initiates industry Business request process, conversation management functional entity can also refuse the service request of terminal after receiving service request.The process meeting Cause the unnecessary energy consumption of terminal and the unnecessary process consumption of network.
To solve the above problems, the application provides a kind of paging method, mobile management function to ps domain entity, which receives, comes from session The notification message of management function entity, the downlink data that notification message is used to indicate the session of terminal reach, and the session is The session of local area data network LADN, notification message include LADN information；If mobile management function to ps domain entity is according to LADN It is overlapping that information determines that the registration area of terminal has with the overlay area of LADN, then mobile management function to ps domain entity pages the terminal. This method first judges the Acceditation Area of terminal when mobile management function to ps domain entity receives the notification information of downlink data arrival It is overlapping whether domain has with the overlay area of LADN, and the ability call terminal when there is overlapping improves the success rate of call terminal, avoids Terminal does invalid service request, reduces the energy consumption of terminal and network side equipment.
With reference to the accompanying drawing, paging method provided by the present application is illustrated.
As shown in figure 3, being a kind of possible network architecture schematic diagram provided by the present application, which includes mobile management Functional entity and conversation management functional entity.

The downlink data that UPF entity receives comes from LADN, and UPF entity judges whether there is downlink N3 tunnel information, if There is N3 tunnel information, shows that the downlink data can be sent to terminal by the PDU session of terminal, terminal is in connected state at this time； If there is no N3 tunnel information, show that downlink data can not be sent to terminal by the PDU session of terminal, terminal is in sky at this time Not busy state or terminal are in connected state but the corresponding PDU session of the downlink data is in deactivated state, therefore, it is impossible to pass through PDU Downlink data is sent to terminal by session.
Wherein, the tunnel N3 refers to the tunnel between RAN equipment (such as base station) and the UPF entity being connected with RAN equipment, described The tunnel N3 is used for transmission the uplink and downlink business datum between terminal and data network (LADN in such as the application).
Step 502, UPF entity sends downlink data notification message to SMF entity, and SMF entity is received from UPF entity Downlink notification message.
When the determination of UPF entity cannot send downlink data to terminal by PDU session, then one is sent to SMF entity Downlink data notification message, for notifying SMF entity to have downlink data arrival.Optionally, include in downlink data notification message PDU session identification.
SMF entity can determine after receiving the downlink data notification message according to the PDU session identification wherein carried The PDU session is a LADN session, and can determine the mark of the corresponding terminal of PDU session identification, that is, be can determine down Which terminal is row data be for.Certainly, if in downlink data notification message not including PDU session identification, can also lead to Cross the mark that other modes know terminal, for example, in downlink data notification message carried terminal mark etc..
Step 503, SMF entity sends response message to UPF entity, and UPF entity receives the response from SMF entity and disappears Breath.
SMF entity sends response message for informing UPF entity to UPF entity, and confirmation receives downlink data notification and disappears Breath.
501~step 503 through the above steps, SMF entity can learn downlink data arrival, and the downlink data Currently terminal cannot be sent to by PDU session.It should be noted that above-mentioned steps 501~503 are optional step, i.e. SMF Entity can also learn downlink data arrival by other means, and the downlink data cannot currently be sent by PDU session To terminal, for example, it may be notifying the SMF entity etc. by other SMF entities, the application is not construed as limiting this.
Step 504, SMF entity send a notification message to AMF entity, and AMF entity receives the notice from SMF entity and disappears Breath.
The downlink data that the notification message is used to indicate the session of terminal reaches, and the session is local area data net The session of network LADN, and further include LADN information in notification message.That is, notification message has in LADN for informing AMF entity The downlink data of PDU session reaches.
Optionally, which, which can also be, issues by other means to AMF entity, for example, by one other Message is sent to AMF entity.
As a kind of implementation, which includes the overlay area of LADN.Optionally, further include in LADN information LADN mark, which is used to indicate the type of the LADN, i.e. LADN mark includes in the LADN information for showing Overlay area be LADN overlay area, rather than the overlay area of other DN.Certainly, if made an appointment, as long as receiving It then must be the overlay area of LADN to the information about overlay area, then there is no need to carry in LADN information Therefore, in LADN information whether LADN mark needs to carry LADN mark, can be depending on practical implementation.Regardless of with what Kind mode, may make AMF entity to obtain the overlay area of a LADN.
As another implementation, which carries data network title (data network name, DNN), The DNN can determine that the corresponding DN of the DNN is a LADN according to the DNN for identifying LADN；Alternatively, LADN packet DNN and LADN mark is included, which cannot judge whether the DNN is LADN according to the DNN for identifying a DN, therefore, Need to indicate that the corresponding DN of the DNN is a LADN by LADN mark, i.e. LAND mark is corresponding for identifying the DNN The type of data network (data netword, DN) is LADN.No matter AMF entity in which way, may make to obtain one The DNN of LADN.
It is overlapping that step 505, AMF entity judge whether the registration area of terminal has with the overlay area of LADN, if there is overlapping, Step 508 is executed, if not being overlapped, executes step 506.
For the registration area of terminal, due to being that AMF entity distributes, AMF entity can get terminal from local Registration area.
For the overlay area of LADN, there are many acquisition modes, for example, in one implementation, if above-mentioned steps 504 In LADN information include LADN overlay area, alternatively, including LADN overlay area and LADN mark, then AMF entity is straight The overlay area that LADN is obtained from LADN information is connect, i.e. the overlay area of LADN is sent to after being got by SMF entity AMF entity.Wherein, SMF entity can be from the local overlay area for getting LADN, be also possible to obtain from PCF entity It arrives, it is of course also possible to be to be got from other entities, the application is with no restrictions.
In another implementation, if the LADN information in above-mentioned steps 504 includes DNN, alternatively, LADN information includes DNN and LADN mark, thus, the available DNN to a LADN of AMF entity, further, AMF entity can basis DNN gets the overlay area of LADN, for example, AMF entity gets covering for LADN corresponding with DNN according to DNN, from local Cover area, for another example, AMF entity send request message to PCF entity, include DNN in request message, the request message is for asking The overlay area for obtaining LADN is asked, after PCF entity receives request message, obtains DNN therein, then according to DNN from local The overlay area of the corresponding LADN of the DNN is obtained, and is carried in response message and is sent to AMF entity.
Step 506, AMF entity sends response message to SMF entity, and SMF entity receives the response from AMF entity and disappears Breath.
Wherein, response message is for notifying SMF entity, and the terminal not in the overlay area of LADN, i.e. do not page by AMF entity Terminal.
Step 507, SMF entity notice UPF entity abandons the downlink data of caching.
It should be noted that above-mentioned steps 506 and step 507 are optionally step, for example, step can be only carried out 506, step 506 and step 507 can also be executed, can also not executed.When executing step 506 and step 507, can make UPF entity abandons the downlink data that cannot be sent to terminal, can save memory space.
So far, process terminates.
Step 508, AMF entity call terminal.
After AMF entity call terminal, terminal starts initiating business request process, establishes PDU session, further, UPF Downlink data is sent to terminal by the PDU session established by entity.Wherein, the process of AMF entity call terminal is existing skill Art, the application do not do expansion explanation, and particular content can refer to pertinent literature record.
So far, process terminates.
The application, 504, step 505 and step 508, AMF entity receive downlink data arrival through the above steps When notification information, it is overlapping first to judge whether the registration area of terminal has with the overlay area of LADN, just paging is whole when there is overlapping End, improves the success rate of call terminal, terminal is avoided to do invalid service request, reduce the energy of terminal and network side equipment Amount consumption.
The application, 504~step 507, AMF entity receive the notification information of downlink data arrival through the above steps When, it is overlapping first to judge whether the registration area of terminal has with the overlay area of LADN, the not call terminal when not being overlapped avoids Terminal does invalid service request, reduces the energy consumption of terminal and network side equipment.
As an example, if terminal is currently located at registration area 3, AMF entity is in the notice for receiving SMF entity with reference to Fig. 2 After message, determine that the registration area 3 of terminal and the overlay area of LADN be not be overlapped, therefore AMF entity is not paged, to save The expense of terminal and network side, because even call terminal, since LADN cannot provide service for terminal, SS later Service request process also still will fail.
For another example, if terminal is currently located at registration area 2, AMF entity is after the notification message for receiving SMF entity, really Determine the registration area 3 of terminal and there is overlapping, therefore AMF entity call terminal in the overlay area of LADN.But it should be recognized that After AMF entity call terminal, the service request process of terminal is also possible to failure, for example, when terminal be located at registration area 2 but The overlapping region of registration area 2 and the overlay area of LADN it is not located at, the service request process of terminal also will fail at this time, only When terminal is located at the overlapping region of registration area 2 and the overlay area of LADN, the service request process of terminal can just succeed.It should Embodiment, while it is not guaranteed that AMF entity, after call terminal, the service request process of terminal can succeed, but compared to more existing It is not call terminal at least in the registration area of terminal and the not be overlapped overlay area of LADN, therefore should for technology Compared to the prior art, the success rate of paging can be improved in embodiment.
As another implementation, to further increase paging success rate and reducing the energy consumption of terminal, the application, In above-mentioned steps 508, AMF entity, can be in paging domain call terminal, wherein paging domain is terminal in call terminal Registration area and LADN overlay area overlapping region.Therefore, if terminal is in paging domain, AMF entity can be with Successful page is to terminal, and the service request process of SS later can also succeed；If terminal not in paging domain, AMF entity not call terminal, thus reduce the energy consumption of terminal, because under the situation, even if call terminal, after terminal Continuous service request process also will fail.For example, referring to fig. 2, terminal is located at registration area 2, and AMF entity only can be at this time The overlapping region call terminal of registration area 2 and LADN, if terminal can page terminal just in the paging domain, if eventually End is not in the paging domain, then the paging of AMF entity is less than terminal, because without triggering following terminal originating service request process, The energy consumption of terminal is saved.
Further, may be replaced by above-mentioned steps 505: when terminal is in Idle state, AMF entity judges terminal Registration area whether have with the overlay area of LADN it is overlapping；When terminal is in connected state, AMF entity judges the covering of LADN Whether region includes cell where terminal.
That is, AMF entity can only get the registration area where terminal when terminal is in Idle state, in this case it is not apparent that eventually TA or cell where end is specific, therefore to judge whether the registration area of terminal has with the overlay area of LADN overlapping for AMF entity. When terminal is in connected state, due to the available cell to terminal where specific of AMF entity, more accurate position is obtained, Therefore, AMF entity judges whether the overlay area of LADN includes cell where terminal.Since the granularity of cell is smaller, when When the overlay area of LADN includes the cell where terminal, indicate that the terminal is in the overlay area of the LADN, paging at this time is eventually End, the registration request process of terminal can succeed；When cell where the overlay area of LADN does not include terminal, the end is indicated End is not in the overlay area of the LADN, and not call terminal, reduces the energy consumption of terminal and network side at this time.The embodiment, at terminal When different conditions, judged using different methods, can further improve the success rate of call terminal, be further reduced end The energy consumption at end.
With reference to Fig. 6, for another paging method schematic diagram provided by the present application, the master with paging method shown in fig. 5 Distinguish are as follows: embodiment shown in fig. 6 be judged whether by SMF entity initiating terminal page, and embodiment shown in fig. 5 be by AMF entity judges whether that initiating terminal is paged.Process shown in fig. 6 may be based on Fig. 3 or framework shown in Fig. 4, lower mask body Explanation.
Step 601~step 603, it is identical as step 501~step 503 in process shown in fig. 5, it can refer to aforementioned retouch It states.
601~step 603 through the above steps, SMF entity can learn downlink data arrival, and the downlink data Currently terminal cannot be sent to by PDU session.But it should be recognized that above-mentioned steps 601~603 are optional step, i.e., SMF entity can also learn downlink data arrival by other means, and the downlink data cannot currently pass through PDU session It is sent to terminal, for example, it may be notifying the SMF entity etc. by other SMF entities, the application is not construed as limiting this.
Step 604, SMF entity judges whether to initiate call terminal, however, it is determined that paging thens follow the steps 606, however, it is determined that no Paging, thens follow the steps 605.
Wherein, when the registration area of terminal has overlapping with the overlay area of the LADN, then terminal initiating terminal is paged, When the registration area of terminal and the not be overlapped overlay area of LADN, then terminal not page by initiating terminal.
Step 605, SMF entity notifies UPF entity, abandons the downlink data of caching.
It should be noted that the step 605 is that optionally step can be such that UPF entity abandons not when executing step 605 It can be sent to the downlink data of terminal, memory space can be saved.
So far, process terminates.
Step 606, SMF entity sends a notification message to AMF entity, and AMF entity receives the notice from SMF entity and disappears Breath.The notification message is used to indicate AMF entity call terminal.
Step 607, AMF entity call terminal.
After AMF entity call terminal, terminal starts initiating business request process, establishes PDU session, further, UPF Downlink data is sent to terminal by the PDU session established by entity.Wherein, the process of AMF entity call terminal is existing skill Art, the application do not do expansion explanation, and particular content can refer to pertinent literature record.
So far, process terminates.
The application, 602, step 604, step 606 and step 607, SMF entity have received lower line number through the above steps According to the notification message of arrival, only when the registration area for determining terminal has overlapping with the overlay area of LADN, just indicate that AMF is real Body call terminal improves the success rate of call terminal, avoids terminal from doing invalid service request, reduces terminal and network side The energy consumption of equipment.
The application, 602, step 604 step 605, SMF entity receive the logical of downlink data arrival through the above steps Know message, when the registration area and the not be overlapped overlay area of LADN for determining terminal, does not then indicate the paging of AMF entity eventually End, avoids terminal from doing invalid service request, reduces the energy consumption of terminal and network side equipment.
For above-mentioned steps 604, SMF entity judges whether to initiate call terminal there are many implementation, and the application combines Attached drawing introduces two kinds of concrete methods of realizing.But it should be recognized that the application is not limited to the two methods, it can also be other Method.
Method one passes through identification information judgment.
SMF entity obtains mark information, which is used to indicate the registration area of terminal and the overlay area of LADN Whether overlapping is had, if identification information is the first label, SMF entity indicates AMF entity call terminal, if mark information is second Label, then SMF entity does not indicate that AMF entity call terminal, the first label are used to indicate the registration area of terminal and covering for LADN Cover area has overlapping, and second marks the registration area for being used to indicate terminal and the overlay area of LADN not be overlapped.
For example, mark information can be a marker bit, value is " 0 " or " 1 ", when mark information value is " 1 ", table The registration area for showing terminal has overlapping with the overlay area of LADN, and here, " 1 " is properly termed as the first label；When mark information takes When value is " 0 ", the registration area and the overlay area of LADN for indicating terminal be not be overlapped, and here, " 0 " is properly termed as the second mark Note.It is of course also possible to be " 0 " indicate terminal registration area have with the overlay area of LADN it is overlapping, " 1 " indicate terminal registration Region and the overlay area of LADN be not be overlapped, and the application is without limitation.
It is of course also possible to be other way to indicate mark information, for example, an arbitrary positive number indicates the first mark Note, arbitrary label of negative number representation second, etc..The mark information that two states can arbitrarily be distinguished, can apply In this application.
In this method one, SMF entity can determine whether by obtaining mark information according to the value of mark information Need to indicate AMF entity call terminal, rapidly and efficiently.
Wherein, the source of mark information can have following implementations:
Implementation one, SMF entity generate mark information and are stored in local.
SMF entity obtains the registration area of terminal and the overlay area of LADN, and the registration area of the terminal according to acquisition And the overlay area of LADN, mark information is generated, and be stored in local.Therefore when SMF entity is needed using mark information, It can be from local acquisition.
For the overlay area for generating LADN used in mark information, can be by SMF entity from local acquisition, it can also To be to be obtained by SMF entity from PCF entity.
For the registration area for generating terminal used in mark information, can be by SMF entity from local acquisition, and The registration area for the terminal that SMF entity is locally stored is reported by AMF entity, for example, in one implementation, SMF is real Body can subscribe to the registration area of terminal to AMF entity, when AMF entity determines that the registration area of terminal updates, then to SMF entity sends the registration area of the terminal updated, so that SMF entity locally saved is the newest Acceditation Area of terminal always Domain, in other words, what SMF entity locally saved is the registration area that terminal is currently located always.
With reference to the accompanying drawing 7 and attached drawing 8 come illustrate SMF entity to AMF entity subscribe to terminal registration area a kind of reality Existing mode.
With reference to Fig. 7, switch to the process schematic of Idle state by connected state for terminal provided by the present application, SMF entity can be The registration area of terminal is subscribed to during this to AMF entity.
Step 701, terminal or AMF entity initiate to deactivate request.
For example, the step 701 can be with if being initiated to deactivate request by terminal are as follows: terminal sends to AMF entity and deactivates Request message；If being initiated to deactivate request by AMF entity, which can be with are as follows: AMF entity, which determines, to be needed to initiate to deactivate Request living.
Step 702, AMF entity sends to SMF entity and deactivates request message.
For example, the deactivation request message, which can be PDU session, deactivates request message, it is used to indicate and deactivates PDU meeting Words.
Step 703, SMF entity sends session modification request message to UPF entity, and UPF entity is received from SMF entity Session modification request message.
It after UPF entity receives the session modification request message, executes and removes tunnel, open the operation such as caching.
Step 704, UPF entity sends response message to SMF entity, and SMF entity receives the response from UPF entity and disappears Breath.
The response message opens the operation such as caching for notifying UPF entity that removal tunnel has been completed.
Step 705, SMF entity determines the registration area for needing to notify AMF entity reporting terminal.
For example, when SMF determines that PDU session is the session of LADN, it is determined that need to notify the note of AMF entity reporting terminal Volume region, can be generated instruction information at this time, and instruction information is used to indicate AMF entity and occurs more in the registration area for determining terminal When new, the registration area of the terminal updated is sent to SMF entity.
Step 706, SMF entity is sent to AMF entity deactivates response message, and the reception of AMF entity is gone from SMF entity Activate response message.
It include above-mentioned instruction information in the deactivation response message.
Step 707, AMF entity discharges resource, and terminal enters Idle state.
701~step 707 of above-mentioned steps enters the normal flow of Idle state for terminal from connected state, and the application is in the stream Cheng Zhong sends an instruction information to AMF entity, for subscribing to the Acceditation Area of terminal by SMF entity through the above steps 706 Domain sends the registration of the terminal updated to SMF entity that is, whenever AMF entity is when the registration area for determining terminal is updated Region.
It should be noted that above-mentioned only by taking terminal enters Idle state from connected state as an example, exemplary to introduce a kind of SMF real The method that body subscribes to the registration area of terminal to AMF entity when practical application, can also be when terminal is in connected state, go It also can also be certainly during activating some PDU session from SMF entity to the registration area that AMF entity subscribes to terminal It is other during from SMF entity to AMF entity subscribe to terminal registration areas, the application to this with no restriction.
As shown in figure 8, being terminal registration process schematic diagram provided by the present application, such as when terminal is in Idle state, eventually The movement at end may triggering terminal register flow path so that AMF entity is that terminal redistributes registration area, and During being somebody's turn to do, AMF entity reports the registration area of the terminal of update to SMF entity, is specifically described below.
Step 801, terminal sends login request message to RAN, and RAN receives the login request message for carrying out self terminal.
For terminal due to the movement of position, triggering terminal initiates register flow path, therefore sends login request message to RAN, uses Network is registered in request.For example, the RAN can be base station etc..
Step 802, RAN selects an AMF entity.
Wherein, which may be the AMF entity that the instruction information from SMF entity is received in Fig. 7, and also having can It can be a new AMF entity.
Step 803, RAN sends login request message to AMF entity, and AMF entity receives the registration request from RAN and disappears Breath.
The login request message is for requesting endpoint to register to network.
Step 804, AMF entity sends information request information to former AMF entity, and former AMF entity sends response to AMF entity Message.
Step 805, former AMF entity sends response message to AMF entity, and AMF entity receives the response from former AMF entity Message.
Wherein, above-mentioned steps 804 and step 805 are optional step, only when the AMF entity of terminal last access with work as It when the AMF entity difference of preceding selection, can just execute, the AMF entity currently selected is to former AMF entity requests contextual information, AMF The contextual information of terminal is carried on the AMF entity for being sent in response message and currently selecting by entity.Also, in the step In 805, it is real to be sent to current AMF for the instruction information from SMF entity that former AMF entity will also receive in Fig. 7 embodiment Body.
Certainly, if the AMF entity of terminal last access is identical as the AMF entity currently selected, the step is not executed 804 and step 805, and the instruction letter that SMF entity is sent in the process of Fig. 7 has been contained in the AMF entity currently selected Breath.
Step 806, AMF entity sends the registration area of terminal to SMF entity according to instruction information.
Here, the registration area for the terminal that AMF entity is sent to SMF entity is newest, that is, whenever terminal is infused When the replacement in volume region, it can all trigger and execute process shown in Fig. 8, then AMF entity can send the current registration area of terminal Give SMF entity, therefore being always maintained at of being locally stored of SMF entity is synchronous with the registration area for the terminal that AMF entity is locally stored, It and is the registration area that terminal is currently located.
Step 807, SMF entity sends response message to AMF entity, and AMF entity receives the response from SMF entity and disappears Breath.
Step 808, other processes are registered.
It should be noted that 801~step 808 of above-mentioned steps is the normal flow that terminal initiates registration, specifically executed Journey can refer to prior art pertinent literature, and the application in this process, increases registration of the AMF entity to SMF entity reporting terminal The operation in region, so that SMF entity can get the registration area of terminal in real time, and then SMF entity can be according to acquisition The overlay area of the terminal arrived current registration area and LADN generates mark information.
Therefore, in the implementation one, SMF can be obtained when generating mark information by Fig. 7 and process shown in Fig. 8 The registration area of terminal is got, and combines the overlay area of LADN, mark information is generated, is stored in local, if also, SMF reality When the mark information of body generation and locally currently stored mark information difference, then SMF entity updates the mark information.
Implementation two, AMF entity generate mark information and are sent to SMF entity.
In the implementation, AMF entity generates label letter according to the overlay area of terminal current registration area and LADN Breath, is sent to SMF entity.
If the registration area of terminal updates, according to the area of coverage of the registration area of updated terminal and LADN Domain regenerates mark information.If also, the new mark information is different from the mark information that AMF is locally stored, that is, after updating The registration area of terminal and the positional relationship of overlay area of LADN change, positional relationship is to have overlapping or without weight Folded, then new mark information is sent to SMF entity by AMF entity, updates the mark information being locally stored by SMF entity.
For example, it is assumed that the currently stored mark information of AMF entity is the first label, the registration area and LADN of terminal are indicated Overlay area have overlapping, if terminal moves, triggering terminal register flow path, AMF entity is the new Acceditation Area of terminal distribution Domain, and according to the overlay area of new registration area and LADN, it determines that mark information is the second label, indicates the current note of terminal Volume region and the overlay area of LADN be not be overlapped, then the mark information that AMF entity reports this new gives SMF entity.If AMF entity According to the overlay area of new registration area and LADN, determines that mark information remains as the first label, then do not report, letter can be saved Enable expense.
The implementation two generates mark information by AMF entity and is reported to SMF entity, and determining mark information When changing, new mark information is just reported to SMF entity.
Method two is judged by the registration area of terminal, the overlay area of LADN.
This method two, SMF entity do not generate mark information, also do not obtain mark information from AMF entity, but are needing When, it is overlapping directly to judge whether the registration area of terminal has with the overlay area of LADN.
That is, when SMF entity needs judge whether to initiate call terminal, SMF entity obtains in step 604 shown in Fig. 6 Take the registration area of terminal and the overlay area of LADN, however, it is determined that the registration area of terminal have with the overlay area of LADN it is overlapping, Then SMF entity indicates AMF entity call terminal, i.e. execution step 606；If it is determined that the registration area of terminal and the area of coverage of LADN Domain is not overlapped, then SMF entity not call terminal, i.e. execution step 605.
Wherein, the overlay area of LADN can be by SMF entity from local acquisition, be also possible to obtain from PCF entity.
Wherein, the registration area of terminal can be through Fig. 7 and method shown in Fig. 8 acquisition, i.e. SMF entity is real from AMF Body subscribes to the registration area of terminal, and SMF entity is sent to when the registration area for determining terminal updates by AMF entity, has Body is referring to foregoing description；The registration area of terminal can also be to be obtained from AMF entity in real time by SMF entity, for example, in Fig. 6 institute Need to use the registration area of terminal in the step 604 for the process shown, then can further execute after step 604: SMF is real Body sends request message to AMF entity, for the registration area of request terminal, then by AMF entity by the registration of terminal Region is sent to SMF entity, to realize when needing to use endpoint to register region, just obtains to AMF entity, can saving signaling Expense.
As another implementation, to further increase paging success rate and reducing the energy consumption of terminal, the application, In above-mentioned steps 607, AMF entity is in paging domain call terminal, wherein paging domain is terminal in call terminal Registration area and LADN overlay area overlapping region, which can be takes in the notification message of step 606 Band, be also possible to individually be sent to AMF entity by other message, therefore, if terminal in paging domain, AMF Entity can be with successful page to terminal, and the service request process of terminal can also succeed at this time；If terminal is not being paged Region, then AMF entity is not paged, thus reduces the energy consumption of terminal, because under the situation, even if call terminal, eventually The service request process at end also will fail.For example, referring to fig. 2, terminal is located at registration area 2, and AMF entity only can be at this time The overlapping region call terminal of registration area 2 and LADN, if terminal can page terminal just in the paging domain, if eventually End is not in the paging domain, then the paging of AMF entity is less than terminal, because without triggering following terminal originating service request process, The energy consumption of terminal is saved.
Further, when above-mentioned steps 604 are realized using the above method two, i.e. step 604 specifically: pass through terminal Registration area, LADN to judge whether the registration area of terminal has with the overlay area of LADN overlapping for overlay area, then at this time should Step 604 may be replaced by: when terminal is in Idle state, SMF entity judges the covering of the registration area and LADN of terminal Whether region has overlapping, when terminal is in connected state, where SMF entity judges whether the overlay area of LADN includes terminal Cell.
That is, SMF entity can only get the registration area where terminal by AMF entity when terminal is in Idle state, The TA or cell being not aware where terminal is specific, therefore SMF entity judges the registration area of terminal and the overlay area of LADN Whether overlapping is had；When terminal is in connected state, since SMF entity can get the specific place of terminal by AMF entity Cell obtains more accurate position, and therefore, SMF entity judges whether the overlay area of LADN includes cell where terminal, by It is smaller in the granularity of cell, when cell where the overlay area of LADN includes terminal, indicate that the terminal is in the LADN's Overlay area, call terminal, the registration request process of terminal can succeed at this time, when the overlay area of LADN does not include terminal institute Cell when, indicate the terminal not in the overlay area of the LADN, then not call terminal at this time reduces terminal and network side Energy consumption.The embodiment is judged using different methods when terminal is in different conditions, can further improve call terminal Success rate, be further reduced the energy consumption of terminal.
