Specific embodiment
Technical solution of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments of the specification.
As shown in Fig. 2, being applied in AMF the present embodiment provides a kind of paging method, comprising:
Step S110: the exclusive paging policy of user equipment (UE) is obtained；
Step S120: according to the exclusive paging policy, in the first area of the registration area of the UE described in paging
UE；
Step S130: it when the paging failure in the first area, is sought in the second area of the registration area
Exhale the UE, wherein the first area and the second area are the different subregions in the registration area.
The registration area of the UE first area and second area have been divided into the present embodiment；The first area and
Different subregions when second area in the registration area of UE.According to the daily scope of activities of UE, the UE appears in first
The frequency in region is higher than the frequency for appearing in the second area.Alternatively, duration of the UE in the first area is greater than
The duration of the second area.Therefore paging is above the probability of the second area to the probability of the UE in first area.
In the present embodiment, when needing to page UE, the UE preferentially is paged in first area, when in first area
When the UE is arrived in failed paging, the UE just is paged in the second area.In compared with the existing technology, directly in the whole of UE
The paging UE in a registration area pages the UE being paged in the high first area of probability due to only limiting, can subtract
The paging of few a large amount of unnecessary second area, so that reducing UE on the whole pages expense.
In step s 110, AMF can be with the exclusive paging policy of UE described in local search, if local inquire this not successfully
The exclusive paging policy of UE, so that it may by requesting to PCF sending strategy, the exclusive paging policy of the UE is inquired in PCF.
In some embodiments, the step S120 can, including at least one of:
According to the exclusive paging policy, the UE in the private network of the UE is paged, wherein the private network paging zone is
The region that the private network that the UE is accessed is covered；
According to the exclusive paging policy, the UE is paged in the special paging zone of the UE, wherein described especially to seek
Exhaling area is the statistical analysis determination based on the behavioral data of the UE.
In the present embodiment, the first area can be the private network paging zone or a behavioral data system based on UE
Count determining special paging zone.The second area can be other other than the deduction first area in the registration area of the UE
Region.
The private network can be sliced corresponding network for network end to end.Communication network can include: wireless domains, core network domain
And domain transmission etc..The wireless domains may include one or more base stations, or at least one resident accesses network (Resident
Access Network, RAN), the core network domain can include: the network functions network element such as MME and GW, AMF, SMF, PCF.It is described
End to end network slice, it may include: the sub-network positioned at the wireless domains of communication network, core network domain and domain transmission is sliced, and is passed through
End to end network slice, terminal can obtain entire specific transactions service.In the present embodiment, the end to end network slice
Referred to as private network is usually to have special-purpose, or for the network of specific transactions transmission, generally correspond to UE registration in wireless domains
Portion of base stations in region.
If UE access is to a private network, it is clear that UE is very high using the probability of the private network, and the wireless domains positioned at the private network are covered
The probability that likelihood ratio within the scope of lid is located at other regions is high.It therefore in the present embodiment, can be by the wireless of the private network of UE access
The coverage area in domain is defined as the private network paging zone.If the first area is the private network paging zone, directly in the special of UE
The paging UE in net paging zone, the paging success rate relative to the paging UE other than private network paging zone is higher, in this way
If, private network paging zone described in priority paging, it is clear that the unnecessary paging other than private network paging zone can be reduced, to reduce
The expense of paging UE.
In some embodiments, the network element of network side, for example, network analysis logic function network element (Network Data
Analytics, NWDA) etc. can analyze the behavioral data of UE to generate the statistic analysis result of behavioral data.The row of the UE
For data can include: the mobile management etc. of UE can determine UE often from which regional access network network, or in which region
Using network, then at this point, determining special paging zone according to the behavioral data of UE, which is the area that UE often haunts
Domain, the probability of paging to UE is very high in the area.For example, the region that UE often haunts in present period, UE at night and
The region often haunted daytime may be different, therefore in the special paging zone of determination, it need to also be distinguished according to the period.Therefore if
The first area is defined as the special paging zone, there will be very big probability only when special paging zone is paged,
The UE is arrived with regard to paging, so as to avoid the paging in other regions other than special paging zone.For example, statistics UE in the predetermined time
The interior number carried out data transmission using base station or cell, is ranked up the number, forward one or more of selected and sorted
A base station, one or more cells construct the special paging zone.In short, the present embodiment can be according to the system of the behavioral data of UE
Meter analysis is as a result, form the exclusive paging policy of the UE.
Further, the step S120 can include:
According to the exclusive paging policy, the UE is paged in the special paging zone；
When the UE is arrived in paging not successfully in the special paging zone, in the private network paging zone described in paging
UE, wherein the private network paging zone is greater than the special paging zone.
It will be paged by different level in first area in the present embodiment, for example, paging institute in special paging zone first
UE is stated, when the UE is arrived in paging not successfully only in special paging zone, just pages UE in entire private network paging zone.
In some embodiments, if the special paging zone has overlapping with the private network paging zone, private network paging is carried out
When the paging in area, can the region only in the private network paging zone other than overlapping region paged.
In further embodiments, if the special paging domain and the private network paging zone be not be overlapped, if special
After the paging failure of paging zone, with regard to directly being paged in entire private network paging zone.
In the present embodiment, the private network paging zone is greater than the special paging zone, the probability being first paged at one
The higher and paging smaller special paging zone of expense is paged, it is clear that can also reduce unnecessary in private network paging zone seek
It exhales, to further reduce the paging expense of UE.
Optionally, the method also includes:
Receive the registration request of the UE；
Based on the registration request, the private network ID of the UE request access is obtained；
It identifies whether the UE has permission and accesses the private network that the private network ID is directed toward；
The exclusive paging policy for obtaining user equipment (UE), comprising:
When the UE has permission the private network for accessing the private network ID direction, connect from the corresponding PCF of SUPI of the UE
Receive the exclusive paging policy.
If needing to adhere to network after UE booting in the present embodiment, registration can be sent to the network element of network side by base station and asked
It asks.The registration that such AMF can receive UE by base station (for example, eNB or next-generation base station (Ng-RAN)) is asked
It asks.In embodiments of the present invention, if AMF receives the registration request, the private network ID of the private network of UE request access can be obtained,
Private network ID can be the information such as any title for indicating corresponding private network and/or number.
For example, the AMF can inquire the private network ID of the private network of the UE request access from other network elements, it is also possible to
The private network ID is extracted from the registration request.Here, other network elements can be next-generation base station.
After determining UE request access or the private network ID for allowing to access, just whether UE is had permission and is linked into pair
The private network answered carries out permission identification.
For example, by current private network ID identify corresponding UE whether have permission be linked into its request access RAN be attached to
Network.
For example, the AMF can also obtain network slice selection assistance information (the Network Slice of the UE
Selection Assistance Information, NSSAI) and/or subscription persistent identifier (Subscription
Concealed Identifier, SUPI) etc..If the NSSAI of the UE is matched with private network ID, if successful match,
Think that the UE has permission the corresponding private network of access, otherwise it is believed that UE does not have permission access.
In another example if further inquiring the UE according to the SUPI that UE is provided when the NSSAI that UE is provided is matched with private network ID
Whether have permission and private network is linked by current RAN, determines that UE has permission if having, otherwise it is assumed that UE does not have permission.
What the NSSAI and SUPI can voluntarily provide for the UE of request registration, pass through NSSAI and SUPI and private network ID
Matching, carry out permission identification.
In further embodiments, the UE itself possibly can not provide NSSAI, then can be by inquiring the signing of the UE
Database obtains the NSSAI of the UE.
The step of above-mentioned permission is identified can be completed by AMF itself, other network elements can also be requested to assist it by the AMF
It completes.For example, in some embodiments, whether the identification UE, which has permission, is accessed the private network that the private network ID is directed toward, packet
It includes:
The private network ID is sent to UDM；
Receive the unified data management network element (Unified Data Management, UDM) transmission based on described
The permission qualification result that private network ID is generated.
For example, the UDM can inquire the private network ID of the accessible private network of the UE, if the private network of UE request access is special
Net ID is the private network ID for the private network that UE is allowed to, then generates the permission qualification result that instruction UE has permission access, if UE request connects
The private network ID of the private network entered is not the private network ID for being the private network that UE is allowed to access, then generates the permission of instruction UE lack of competence access
Qualification result.
In some scenes, the UDM can permit the private network ID of the private network of access with local search UE.If UDM sheet
Ground does not inquire the private network ID of the private network of UE request access, then UDM inquires the UE from other network elements such as subscribed database and permits
Perhaps the private network ID of the private network accessed, to generate the permission qualification result.In the present embodiment, other described network elements can be described
Private network provides the book server of service.The book server can be third-party server, the business service of the book server
It needs to provide communication service etc. by corresponding private network.The book server can be enterprise servers, for example, the enterprise servers
Live data can be provided can be carried out data transmission by corresponding private network, if the not stored private network for having UE request access in UDM
Private network ID, then UDM can inquire whether the UE has permission access to the corresponding book server of private network ID.
The UDM is based on NSSAI, SUPI, and private network ID identifies whether UE can adhere to the permission identification of network by the RAN
It can be as follows:
If UE has NSSAI, compare whether NSSAI matches with private network ID, mismatches then UE and have no right to access private network；
If UE does not provide NSSAI, UDM obtains the NSSAI of UE by inquiry signing information, with private network ID comparison whether
Matching mismatches then UE and haves no right to access private network
If NSSAI is matched with private network ID, go at the corresponding exclusive server of private network to inquire whether the UE has based on SUPI
Power accesses private network by the RAN.
The AMF receives the permission qualification result that the UDM is provided.The AMF is based on the permission qualification result
Determine whether the registration of the UE.If allowing the UE's to be registered to corresponding private network, in order to facilitate subsequent paging institute
State AMF in step s 110 can include:

Step 1: NSSAI, SUPI and private network ID are reported to UDM by AMF, to realize UDM to the identity authentication of UE；
Step 2: UDM is based on NSSAI, SUPI, private network ID identifies whether UE can adhere to network by the RAN；
Step 3: AMF obtains exclusive paging policy from PCF, the parameter carried include but is not limited to NSSAI, SUPI,
Private network ID；
Step 4: preferentially being paged in special paging zone when UE is in CM-IDLE state, sought if UE is without response in private network
Area is exhaled to page, if still without response, the RAN in the whole region of UE registration is paged.
The special paging zone described in this example is determined based on the daily moving range of UE, and the private network paging zone is base
Determining in the network slice of UE registration.Under normal circumstances, a private network corresponds to several base stations in the registration area of UE, and
Not every base station.Special paging zone may generally correspond to one or several base stations.Special paging zone is that UE often haunts
Position is the current optimal possible location UE, therefore is preferentially paged in special paging zone, has very high probability to seek
Exhale UE.If not paging UE in special paging zone, paged in UE registration or ownership private network, relative to spy
Other paging zone, the corresponding paging domain of private network paging is larger, and in this case, the paging relative to special paging zone increases
The probability that UE is paged.If UE is arrived in the failed paging of private network paging, the whole network paging of the registration area of UE is carried out, thus really
Guarantor can finally page UE.
Due to the region that the paging of special paging zone and the private network paging UE high frequency time that has all been priority paging occur, have very big
Probability UE is paged in special paging zone or in the private network of private network paging, and is paged without carrying out the whole network of registration area,
To reduce paging expense.
For example, the working time of such as certain UE (Mon-Fri) on weekdays, (NWDA can analyze out the specific time
Section, such as 9:00~18:00), use the office private network of China Mobile's ChuangXin Building；And public affairs are used except the above period
Net, position distribution are predominantly located at family and major outdoor sight spot.Based on information above, when UE is in CM-IDLE state, AMF makes
It is paged with when registration from the paging policy that PCF is obtained.If it is workaday working hour, then in China Mobile, innovation is big
It is paged under one or several base stations in tall building, if not receiving UE response in specified time, uses the whole in UE registration
It is paged in region.The office private network is one kind of the private network of aforementioned end to end network slice.If working day first leads to
Private network paging UE is crossed, the whole network paging of registration area is just carried out in the case where paging failure, it is clear that reduce and participate in paging
Base station reduces base station and sends running time-frequency resource and/or power consumption consumed by paging message, therefore reduces paging consumption, and can
Ensure that UR can be still paged.
Example 2:
As shown in figure 8, this example provides the register method of UE a kind of, comprising:
1, UE sends registration information to RAN.
2, RAN is based on NSSAI and RAT and selects AMF；

4, AMF is based on SUPI and private network ID and selects AUSF；
5, AMF is based on SUPI and private network ID and selects UDM；
6, AMF reports SUPI, NSSAI, private network ID to UDM, request user identity identification, UDM according to NSSAI, private network ID,
SUPI inquired in local cache the user whether be the private network registration equipment.For example, from CMRI (for example, enterprise servers)
Middle acquisition subscriber identity information, for example, using the subscriber identity information of the corresponding private network of private network ID, for request registration
User carries out permission identification.
7, if do not found in local cache as a result, if UDM according to private network ID, SUPI, NSSAI, to the exclusive service of enterprise
Device (in figure for moving research institute CMRI) inquires whether the UE is private network registration user；
8, query result is returned to AMF by UDM；
9, AMF is based on SUPI and selects PCF；
10a, AMF obtain access and the mobility strategy of UE from PCF, and PCF has been looked for whether from local cache first
The exclusive paging policy of the UE；If 10b, the local exclusive paging policy without the UE cache, PCF, which is based on private network ID, to be returned
Give UE mono- private network paging zone, which is base station granularity in private network.PCF obtains UE's based on SUPI from NWDA simultaneously
Behavioural habits, zone of action (Activity Area) generate a special paging zone (Special Tacking Area).If
There are no the records about the UE in NWDA, then report the primary analysis sample as NWDA.PCF be based on private network paging zone and
The special paging zone (Special Tacking Area) that NWDA is provided, generates exclusive paging policy.Step 10a and step 10b,
