3)LADN

The concept of LADN is introduced in 5G.UE can only be in specific region, the coverage of specific region i.e. LADN, The local data network can just be accessed.The foundation of PDU session is based on application, therefore for suitable for LADN in 5G Using when UE is only located in LADN SA, could establish and use data network is the PDU session of LADN.For example, referring to figure Shown in 2A, RA1~RA3 is 3 registration areas that network divides, and altogether includes that TA1~TA12 amounts to 12 tracking area (tracking Area, TA), TA1~TA5 supports that LADN, i.e. LADN SA are TA1~TA5, i.e. LADN can across registration area distribution.It needs Bright, LADN SA is to illustrate by granularity of TA, but be not intended to limit using other granularities and characterize LADN SA in the present invention, Such as cell (cell) granularity etc..In conjunction with the coverage of LADN, data network or data network name mentioned in the present invention When corresponding coverage being claimed to refer both to UE in corresponding coverage, the PDU meeting that DNN is the data network title could be initiated The activation operation of foundation, modification, deletion or the connection of user face of words.

In order to distinguish, the LADN information for being allocated to UE in the prior art is known as the first LADN information.Match in the prior art Set the data network title including the UE LADN being able to use in current registration area in the first LADN information to UE And its corresponding service region information, it should be noted that when the data network title and the LADN of the LADN being able to use When the corresponding service region information of data network title has multiple, the first LADN information includes the number of multiple LADN being able to use According to the set of the corresponding service region information of the data network title of network name and each LADN.Wherein, the first LADN information It is AMF according to local about the network name of the configuration of LADN, the position of UE and the UE LADN to contract is that UE is configured.AMF On the local configuration about LADN can be through operation and maintenance management system (Operation Administration and Maintenance, OAM) it is allocated to AMF).The network name and service region information of LADN is to go out in pairs in the first LADN Existing.

Such as: the DNN of the LADN of UE signing includes DNN1, DNN2 and DNN3.UE can make in current registration area The network name of LADN includes DNN1, DNN2.And it is directed to DNN3, the corresponding coverage DNN3 is not in the registration area of UE The LADN of DNN3 is not configured on interior or AMF, so that UE is not available in current registration area, thus in the first LADN information It does not include DNN3 and corresponding service region information.It include the following: DNN1 in first LADN information, the corresponding service area of DNN1 Domain information；The corresponding service region information of DNN2, DNN2；It can specifically be expressed as format: the first LADN information [DNN1, DNN1-Service Area], [DNN2, DNN2-Service Area] }.It should be noted that if UE is in current Acceditation Area If corresponding three LADN of DNN1, DNN2, DDN3 are unable to use in domain, the first LADN information does not include any content, Correspondingly, UE not will receive the first LADN information.

It is understood that the LADN that UE is able to use refers to that if UE is located within the corresponding coverage the LADN, The PDU session that the LADN (i.e. the data network of the corresponding DNN instruction of PDU session is the LADN) can be initiated to be linked into is built Vertical/modification/deletion/user face connection activation request, to receive the service of LADN offer.

Determine that a LADN is that the LADN that UE is able to use needs to meet following all conditions:

Condition one, UE's LADN have contracted, i.e. UE has the subscription data using the LADN；

The LADN and its corresponding coverage LADN are configured in condition two, AMF, i.e. the AMF supports the LADN；

Condition three, UE registration area include the coverage of LADN, i.e. there is friendship in UE registration area and the coverage LADN Collection.

In order to distinguish, the coverage of the LADN configured on AMF is known as first service region in the present invention, AMF is sent It is known as second service region to the coverage of the LADN of UE, wherein second service region is the registration area and first service of UE The intersection in region.

Specifically, the DNN of the UE LADN to contract is allocated to AMF by network side PCF or UDM, and AMF is for UE configuration the When one LADN information, the DNN according to local about the configuration of LADN, the position of UE and the UE LADN to contract configures first for UE LADN information, AMF only make the corresponding second service region the DNN and DNN of the UE LADN that can be used in registration area UE is sent to for the first LADN information.It that is include the DNN and second service area information of LADN in the first LADN information.Such as Fig. 2 B It is shown, by taking AMF is configured with a LADN as an example, become first LADN, which is the LADN of UE signing, first service area Domain includes TA1-TA5 totally 5 TA.When terminal is located at RA1, the second service region received is TA1-TA4 totally 4 TA, and eventually End in RA2, the second service region received is only TA5, when terminal is located at RA3, due to no second service region (RA3 and First service region is without intersection), therefore the LADN can not be used on RA3 by UE, AMF will not configure the first LADN letter for UE Breath.

It should be noted that referred to as first LADN and second LADN works as end if AMF configuration is there are two when LADN When end is located at RA3, if second LADN is the LADN that terminal is able to use, AMF can configure the first LADN information for UE, but It only include the corresponding second service region corresponding DNN and first LADN of first LADN in first LADN information.

UE is located in registration area RA3, needs to initiate the foundation modification of PDU session, modification, deletes, activation user face company When connecing, if the DNN of the PDU session association is the DNN of first LADN, due in RA3 without the coverage of LADN, AMF, which is not configured, before gives the UE any LADN information, i.e. UE is without the first LADN information.Therefore UE can not determine the PDU session Associated DNN is the DNN of LADN, therefore does not determine whether to be located in corresponding second service region, but directly initiates PDU The process (establishing, the process of activation or modification PDU session) of session.The data network indicated due to the DNN of the PDU session association Network is LADN, and UE is located at except first service region or second service region, therefore network side can refuse the correlation of UE Request, so as to lead to signaling resource wastage.

Based on this, the embodiment of the present application proposes the indicating means and device of local data network, for solving signaling money The problem of source wastes.Wherein, method and apparatus are the principles solved the problems, such as due to method and device based on the same inventive concept It is similar, therefore the implementation of apparatus and method can be with cross-reference, overlaps will not be repeated.

In order to solve the problems, such as above-mentioned signaling resource wastage, the embodiment of the present application proposes following three kinds of modes:

The first possible mode is: if the data network of some DNN instruction is LADN, configuring the DNN to UE When, it will indicate that the DNN is that the instruction information of LADN is allocated to the UE together.It is specifically described by following examples one.

Second of possible mode is: the DNN of the UE all LADN to contract is allocated to UE.Pass through following examples Two are specifically described.

The third possible mode is: proposing that a kind of mode of new configuration LADN information will pass through for convenience The LADN information of which configuration is known as the 2nd LADN information.It is specifically described by following examples three.

Wherein, UE described in the DNN set and DNN set of the LADN including UE signing in the 2nd LADN information The corresponding service region information of the network name for the LADN being able to use in current registration area (second service region).It is described It does not include the corresponding service region information of DNN of the non-serviceable LADN of UE in the DNN set in 2nd LADN information.It needs Illustrate, determine that a LADN is that the non-serviceable LADN of UE needs to meet following condition in the embodiment of the present application:

The UE unsigned LADN, i.e. UE do not use the subscription data of the LADN；

The LADN and its corresponding coverage LADN are not configured on AMF, i.e. the AMF does not support the LADN；

The registration area of UE does not include the coverage LADN, i.e., endpoint to register region is not handed over the coverage LADN Collection.

Above-mentioned three kinds of modes provided by the embodiments of the present application are specifically described with reference to the accompanying drawing.

Embodiment one:

It is shown in Figure 3, it is specifically described for the first possible mode.

The data network of some DNN instruction is LADN, when configuring the DNN to UE, will indicate the corresponding data network of the DNN Network is that the instruction information of LADN is allocated to the UE together.

It should be noted that the data network of some DNN instruction is LADN, DNN mark can be understood as on technological essence The data network of knowledge is LADN, or can be understood as the DNN is the corresponding DNN of a LADN.Two kinds are described in the present invention Mode does not do technical specific differentiation.

Configuration mode may include:

1) it is pre-configured to be in UE, such as when UE contracts the LADN, DNN and instruction information configuration is identified in Global Subscriber Module (universal subscriber identity module, USIM) or Universal Integrated Circuit Card (universal Integrated circuit card, UICC) in.

2) by configuration device configuration to UE, such as by downloading (over-the-air, OTA) technology, open movement in the air The modes such as alliance device management (open mobile alliance-device management, OMA-DM) are allocated to UE.

3) data network of the DNN and DNN instruction is carried in the strategy configured for UE by the first equipment of the core network It is the instruction information of LADN.Such as the strategy is configured by equipments of the core network such as UDM, PCF, MME, AMF or SMF, and pass through letter Order is sent to UE.

S301, UE obtain the first information.

Wherein, the first information includes the instruction of the first DNN and first, and first instruction is used to indicate described first The data network of DNN instruction is LADN；Alternatively,

The first information includes the first DNN, and the first DNN includes the second instruction, and second instruction is used to indicate The data network of the first DNN instruction is the LADN.

It is to be understood that the data network of the first DNN instruction is LADN, it can be understood as the data of the first DNN mark Network is LADN.The data network that i.e. described first instruction is used to indicate the first DNN mark is LADN.Wherein, LADN is corresponding DNN can be understood as the DNN that the DNN is a LADN.It should be noted that the implementation of the first instruction may include as follows Implementation:

First is designated as the subparameter in an independent parameter or a parameter, is also possible to an indicating bit.

First instruction can indicate whether that the data network of instruction is LADN by value 0 or 1, when value is 0 table Show that the first DNN is not the corresponding DNN of LADN；Indicate that the first DNN is the corresponding DNN of LADN when value is 1.Or it is on the contrary.When Whether the data network that the first DNN instruction can also be so indicated by other values is LADN.

The subparameter in an independent parameter or a parameter is designated as when first, when the first DNN is LADN corresponding DNN when, the first information include first instruction；When the first DNN is not LADN corresponding DNN, the first information does not include the first finger Show.

The implementation of second instruction may include following implementation:

It optionally, is institute according to the data network that the first information determines that the first DNN is indicated in step S302, UE After stating LADN, when determining that the UE does not save the first LADN information, then the PDU session establishment/repair is not sent to SMF Change/delete/request message, also not to AMF send activation user face connect request message.It is understood that UE is not protected The first LADN information is deposited, UE can determine current location except the corresponding coverage the first DNN.

It should be noted that UE not to equipment of the core network (AMF/SMF) send PDU session establishment/modification/deletion/ask Seek message, it can be understood as UE cannot initiate PDU session establishment/modification/deletion/activation user face connection process, Huo Zheke This PDU session establishment/modification/deletion/activation user face connection process (or process) is terminated to be interpreted as UE.

It optionally, is institute according to the data network that the first information determines that the first DNN is indicated in step S302, UE After stating LADN, if determining that the UE is located at except the corresponding coverage the first DNN according to the first LADN information, Then PDU session establishment/modification/activation request message is not sent to SMF.

Wherein, determine that the UE is located at the clothes of the data network of the first DNN instruction according to the first LADN information It is engaged in except region, can be accomplished in that

If it is determined that the first LADN information does not include the corresponding coverage letter of the first DNN and the first DNN In breath at least one of when, it is determined that the UE be located at the first DNN indicate data network coverage except；Or Person, however, it is determined that the first LADN information includes the first DNN and the corresponding service region information of the first DNN, but root Determine that the UE is located at the service of the data network of the first DNN instruction according to the corresponding service region information of the first DNN Except region.

Shown in Figure 5, optionally, in step s 304, UE determines that the UE is located at according to the first LADN information When the corresponding coverage the first DNN, after establishing the request message of the PDU session to AMF transmission, the method may be used also To include:

S305, UE save the second information, and second information is used to indicate the number of the corresponding DNN instruction of the PDU session It is the LADN according to network.

To after saving second information, however, it is determined that when needing to modify or activate the PDU session, the method Can also include:

S306, UE determine the number of the corresponding DNN instruction of PDU session of the to be modified/activation according to second information It is the LADN according to network.The PDU session for determining to be modified/activation is the PDU session of LADN.

S307, UE determine that the first LADN information includes the corresponding service region information of the LADN.

When S308, UE determine that the UE is located at the coverage of the LADN according to the service region information, to first Equipment of the core network sends the request message of activation (or modification) PDU session.The PDU is activated specifically, sending to the AMF The service request information of the user face connection of session is asked by AMF to the PDU session modification that SMF sends the modification PDU Seek message.Sending in S308 using UE to the AMF activates the request message of the PDU session as example.

Optionally, UE is not when determining the LADN information includes the service region information of the LADN, not to the AMF The service request information for activating the user face connection of the PDU session is sent, does not also send modification/deletion PDU's to SMF PDU session modification request message；Alternatively, not sent to the AMF when UE determines the first LADN information without preservation The service request information for activating the user face of the PDU session to connect also is not repaired to the PDU session that SMF sends the modification PDU Change request message.

The scheme provided by embodiment one can be directly according to the configuration of UE after UE is matched to a DNN according to URSP Information or URSP know that the data network whether DNN indicates is LADN, whether determine whether to execute inspection UE at this The movement of the coverage LADN.In addition, saving the data network of the corresponding DNN instruction of the PDU after the PDU session that UE establishes LADN Network is the information of LADN, thus it is subsequent for the session modify or activate again user face connect when, can direct root The data network that the PDU corresponding DNN instruction is determined according to the information of preservation is LADN, thus again determine whether to initiate to establish/ Modification/active session process.

Embodiment two:

It is shown in Figure 6, it is specifically described for second of possible mode.

Second of possible mode is: the corresponding DNN of all LADN that the UE contracts is allocated to UE.

Configuration mode is as in the first embodiment, may include:

1) it is pre-configured to be in UE.Such as when UE contracts one or more LADN, by one or more LADN's DNN configuration is in Global Subscriber identification module (universal subscriber identity module, USIM) or general In integrated circuit card (universal integrated circuit card, UICC).

2) UE is allocated to UE, such as by UDM or PCF by configuration device configuration.For example pass through OTA technology, OMA-DM Etc. modes be allocated to UE.

3) You Xiang UE is allocated to UE by the first equipment of the core network during registering to network side.Such as by UDM, The equipments of the core network such as PCF, MME, AMF or SMF configure this and include the parameter of the corresponding DNN of all LADN of UE signing, and lead to It crosses signaling and is sent to UE.

Specifically, the indicating means of LADN includes:

S601, UE get parms, and the parameter includes the DNN set of the local data network LADN of the UE signing.

It should be noted that if the DNN of the LADN of UE signing is one, then it include a DNN in DNN set, if UE is signed The DNN of LADN about is multiple, then includes multiple DNN in DNN set.I.e. UE Subscribed LADN LADN1, LADN2 ... }

S602, UE determine the first DNN.

It should be noted that UE determines that the first DNN can be according to URSP, i.e. UE is after triggering some application, according to URSP It determines a certain rule in application matching URSP, includes the first DNN in the rule.Alternatively, terminal is true by other means When establishing a PDU session surely, the corresponding DNN of the PDU session is the first DNN, and the application is to the specific side for determining the first DNN Formula is without limitation.

S603, UE determine that the DNN set includes the first DNN.

It is understood that UE determines the first DNN instruction when UE determines that the DNN set includes a DNN Data network is the LADN, and further, UE determines whether to be located within the corresponding coverage the first DNN；When UE is determined When the DNN set does not include a DNN, UE determines that the first DNN is not the corresponding DNN of the LADN, i.e. the first DNN refers to The data network shown is a non-LADN.If the first DNN is not the corresponding DNN of the LADN, whether UE is located at without executing Judgement within the corresponding coverage first DNN is being initiated to establish, modification, is deleting or activate and use to equipment of the core network Before the request message of family face connection, without judging UE within the corresponding coverage the first DNN.

S604, UE determine that the UE whether in the coverage of the first data network, if so, executing S605, is held if not Row S606.First data network is the data network of the first DNN instruction.

When determining whether the UE is located in the coverage of the first data network, can specifically be believed according to the first LADN Whether breath determines the UE in the coverage of the first data network.

Wherein, the first LADN information includes the network name for the LADN that the UE is able to use in current registration area Title and its corresponding service region information.
