Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.
1) Data network name
The data network name related in the embodiment of the present application may be a Data Network Name (DNN) or an Access Point Name (APN), and the DNN and the APN are not specifically distinguished. In the embodiment of the present application, a network name DNN is taken as an example for explanation, and for an implementation manner based on an APN, reference may be made to description of the implementation manner based on the DNN in the embodiment of the present application, and details are not described again.
In the present application, the plurality of the present invention means two or more. Meanwhile, it should be understood that although the terms first, second, etc. may be used to describe various information, network names in the embodiments of the present application, the information, network names should not be limited to these terms. These terms are only used to distinguish one unit from another.
2) User routing Policy (UE Route Selection Policy, URSP):
the URSP is used for the UE to determine whether the triggered application can associate a PDU session already established by the terminal or newly establish a PDU session.
In 5G, the establishment of the PDU session is triggered by an application, and different applications have different requirements for PDU session attributes, such as network slice (network slice), DNN, and session and service connectivity mode (SSC mode). Different applications may trigger the establishment of different PDU sessions. Therefore, 5G introduces a URSP for the UE to determine whether data corresponding to an application can be associated to an existing PDU session transfer or whether a PDU session can be newly established for transfer.
For an application, after matching URSP, corresponding PDU session parameters can be obtained, if a PDU session meeting the parameter requirement exists, the application is associated to the PDU session, and if the PDU session not meeting the requirement does not exist, a PDU session is newly established.
The following information may be included in the URSP:
a policy priority;
traffic descriptor (traffic descriptor):
application (application) identification;
a network Protocol (IP) descriptor;
a non-IP (non-IP) descriptor;
path selection descriptor (route selection descriptor):
SSC mode selection;
selecting a network slice;
DNN selection;
a non-seamless offload indication (non-seamless offload indication) indicating whether to offload to a non-third Generation Partnership Project (3rd Generation Partnership Project 3 GPP);
access type preference (access type preference) for indicating adoption of 3GPP or non-3 GPP.
3)LADN
The concept of LADN was introduced in 5G. The UE can access the local data network only in a specific area, i.e. the service area of the LADN. The establishment of PDU sessions in 5G is application based, so for applications applicable to LADN, a PDU session for a data network to be LADN can only be established and used by the UE if it is located within the LADN SA. For example, as shown in fig. 2A, RA1 to RA3 are 3 registration areas divided by the network, and include 12 Tracking Areas (TAs) in total from TA1 to TA12, and TA1 to TA5 support LADN, that is, the LADN SA is TA1 to TA5, that is, the LADN may be distributed across the registration areas. It should be noted that the LADN SA in the present invention is exemplified by TA as granularity, but the use of other granularities to characterize the LADN SA is not limited, such as cell granularity and the like. In combination with the service area of the LADN, the data network or the service area corresponding to the data network name mentioned in the present invention refers to that the setting up, modification, deletion or activation operation of the user plane connection of the PDU session with the DNN as the data network name can be initiated only when the UE is in the corresponding service area.
For the sake of distinction, the LADN information configured to the UE in the related art is referred to as first LADN information. In the prior art, first LADN information configured for a UE includes a data network name of a LADN that can be used by the UE in a current registration area and service area information corresponding to the data network name, and it should be noted that when there are a plurality of data network names of the LADNs that can be used and service area information corresponding to the data network name of the LADN, the first LADN information includes a set of the data network names of the LADNs that can be used and the service area information corresponding to the data network name of each LADN. Wherein the first LADN information is configured by the AMF according to the local configuration of the LADN, the position of the UE and the network name of the LADN subscribed by the UE. The configuration of the local LADN on the AMF may be through an Operation Administration and Maintenance (OAM) system configured to the AMF). The network name of the LADN and the service area information are present in pairs in the first LADN.
For example: the DNNs of the LADNs to which the UE subscribes include DNN1, DNN2, and DNN 3. The network names of the LADN that the UE can use in the current registration area include DNN1 and DNN 2. For DNN3, the service area corresponding to DNN3 is not in the registration area of the UE or the AMF is not configured with the LADN of DNN3, so that the UE cannot be used in the current registration area, and the first LADN information does not include DNN3 and the corresponding service area information. The first LADN information includes the following: service area information corresponding to DNN1 and DNN 1; service area information corresponding to DNN2 and DNN 2; specifically, the following format can be expressed: the first LADN information { [ DNN1, DNN1-Service Area ], [ DNN2, DNN2-Service Area ] }. It should be noted that, if none of the three laddms corresponding to DNN1, DNN2, and DDN3 in the current registration area can be used, the first LADN information does not include any content, and accordingly, the UE does not receive the first LADN information.
It can be understood that the LADN that the UE can use means that the UE can initiate a PDU session setup/modification/deletion/user plane connection activation request for accessing the LADN (that is, the data network indicated by the DNN corresponding to the PDU session is the LADN) as long as the UE is located in the service area corresponding to the LADN, so as to receive the service provided by the LADN.
Determining one LADN as a LADN that can be used by the UE requires all of the following conditions to be satisfied:
the first condition is that the UE signs a contract for the LADN, namely the UE has subscription data using the LADN;
secondly, configuring the LADN and a corresponding LADN service area on the AMF, namely the AMF supports the LADN;
and thirdly, the registration area of the UE comprises a service area of the LADN, namely the registration area of the UE and the service area of the LADN have intersection.
For the purpose of differentiation, the service area of the LADN configured on the AMF is referred to as a first service area, and the service area of the LADN sent by the AMF to the UE is referred to as a second service area, where the second service area is an intersection of the registration area of the UE and the first service area.
Specifically, the PCF or UDM on the network side configures DNN of the LADN subscribed by the UE to the AMF, and when the AMF configures the first LADN information for the UE, the AMF configures the first LADN information for the UE according to the local configuration of the LADN, the location of the UE, and the DNN of the LADN subscribed by the UE, and the AMF sends only DNN of the LADN that the UE can use in the registration area and the second service area corresponding to the DNN as the first LADN information to the UE. That is, the first LADN information includes DNN of the LADN and the second service area information. As shown in fig. 2B, taking the AMF configured with one LADN as an example, it is the first LADN, which is the LADN subscribed by the UE, and the first service area includes 5 TAs, TA1-TA 5. When the terminal is located in RA1, the received second service area is 4 TAs, TA1-TA4, and when the terminal is located in RA2, the received second service area is only TA5, and when the terminal is located in RA3, since there is no second service area (RA3 does not intersect with the first service area), the LADN cannot be used by the UE on RA3, and the AMF does not configure the first LADN information for the UE.
It should be noted that, if the AMF is configured with two ladders, it is referred to as a first ladder and a second ladder, and when the terminal is located in RA3, if the second ladder is a ladder that can be used by the terminal, the AMF may configure first ladder information for the UE, but the first ladder information only includes a DNN corresponding to the first ladder and a second service area corresponding to the first ladder.
When the UE is located in the registration area RA3 and needs to initiate the establishment, modification, deletion, and activation of the PDU session, if the DNN associated with the PDU session is the DNN of the first LADN, since there is no service area of the LADN in RA3, the AMF is not configured with any LADN information for the UE before, that is, the UE does not have the first LADN information. Therefore, the UE cannot determine that the DNN associated with the PDU session is the DNN of the LADN, and therefore, cannot determine whether the DNN is located in the corresponding second service area, but directly initiate a procedure of the PDU session (a procedure of establishing, activating, or modifying the PDU session). Since the data network indicated by the DNN of the PDU session association is the LADN and the UE is located outside the first service area or the second service area, the network side may reject the related request of the UE, which may result in a waste of signaling resources.
Based on this, the embodiment of the application provides an indication method and an indication device for a local data network, which are used for solving the problem of signaling resource waste. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
In order to solve the problem of the signaling resource waste, the embodiment of the present application provides the following three ways:
a first possible way is: if the data network indicated by a certain DNN is a LADN, when the DNN is configured to the UE, indication information indicating that the DNN is the LADN is configured to the UE together. This is illustrated in detail by the following example one.
A second possible way is: and configuring DNN of all LADN subscribed by the UE to the UE. The following example two will be used to illustrate the details.
A third possible way is: a new way of configuring the LADN information is proposed, and for convenience of description, the LADN information configured by this way is referred to as second LADN information. The following example III is used for specific illustration.
The second LADN information includes a DNN set of LADNs subscribed by the UE, and service area information (second service area) corresponding to a network name of a LADN that can be used by the UE in the current registration area in the DNN set. The second LANN information does not include service area information corresponding to DNN of the LANN which cannot be used by the UE in the DNN set. It should be noted that, in the embodiment of the present application, determining one LADN as an LADN that cannot be used by the UE needs to satisfy the following conditions:
the UE does not subscribe to the LADN, i.e., the UE does not use subscription data of the LADN;
the LADN and the corresponding LADN service area are not configured on the AMF, namely the AMF does not support the LADN;
the registration area of the UE does not include the LADN service area, i.e. the terminal registration area and the LADN service area do not intersect.
The three modes provided by the embodiments of the present application are specifically described below with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 3, a first possible way is specifically described.
When a DNN is configured to a UE, indication information indicating that the data network corresponding to the DNN is a LADN is configured to the UE.
It should be noted that a DNN indicates a data network is a LADN, and in the technical essence, a DNN identifies a data network as a LADN, or a DNN corresponding to a LADN. . The two descriptions in the present invention are not technically distinguished.
The configuration mode can include:
1) the DNN and the indication information are pre-configured in the UE, for example, when the UE signs up for the LADN, the DNN and the indication information are configured in a Universal Subscriber Identity Module (USIM) or a Universal Integrated Circuit Card (UICC).
2) The UE is configured by the configuration device, for example, through over-the-air (OTA) technology, open mobile alliance device management (OMA-DM), and the like.
3) And carrying the DNN and indication information that the data network indicated by the DNN is the LADN by the first core network equipment in a strategy configured for the UE. The policy is configured by core network equipment such as UDM, PCF, MME, AMF, or SMF, and is signaled to the UE.
S301, the UE acquires first information.
Wherein the first information comprises a first DNN and a first indication indicating that a data network indicated by the first DNN is a LADN; alternatively, the first and second electrodes may be,
the first information comprises a first DNN comprising a second indication indicating that a data network indicated by the first DNN is the LADN.
It can be understood that: the data network indicated by the first DNN is a LADN, which is understood to mean that the data network identified by the first DNN is a LADN. I.e. the first indication indicates that the data network identified by the first DNN is a LADN. Wherein, DNN corresponding to LADN can be understood as DNN of a LADN. It should be noted that, the implementation manner of the first indication may include the following implementation manners:
the first indication is an independent parameter or a sub-parameter in a parameter, and may also be an indication bit.
The first indication can indicate whether the indicated data network is a LADN by taking a value of 0 or 1, and when the value is 0, the first DNN is not a DNN corresponding to the LADN; when the value is 1, the first DNN is the DNN corresponding to the LADN. Or vice versa. Of course, it may also be indicated whether the data network indicated by the first DNN is a LADN by other values.
When the first indication is an independent parameter or a sub-parameter in a parameter, when the first DNN is a DNN corresponding to the LADN, the first information includes the first indication; the first information does not include the first indication when the first DNN is not a DNN to which the LADN corresponds.
Implementations of the second indication may include implementations as follows:
an indicator bit is added in the structure of the first DNN, the value of the indicator bit can be 0 or 1, and when the value is 0, the first DNN is not the DNN corresponding to the LADN; when the value is 1, the first DNN is the DNN corresponding to the LADN. Or vice versa. The indication bit can be added to the head, tail or any middle position in the DNN structure, and the specific position of the indication bit in the DNN structure is not limited by the present invention.
And after the UE triggers a certain application, when the application is matched with the first DNN according to the URSP, determining whether the data network indicated by the first DNN is a LADN or not according to the first information.
And when the UE determines that a PDU session needs to be modified or activated, the UE determines that the PDU session corresponds to the first DNN, and then determines whether the data network indicated by the first DNN is a LADN or not according to the first information.
It should be noted that: the PDU session corresponds to said first DNN, it being understood that the DNN parameter of the PDN session is the first DNN; or the DNN used by the PDU session is the first DNN; or the PDU session is a connection between the providing terminal and the first DNN; or the PDN session is accessed to the first DNN.
S302, the UE determines that the data network indicated by the first DNN is the LADN according to the first information.
It may be understood that, the UE determines, according to the first information, that the data network indicated by the first DNN is the LADN, or may also be understood that, according to the first information, the UE determines that the data network identified by the first DNN is the LADN.
Optionally, the method may further include:
s303, the UE determines that the first LADN information includes the first DNN and service area information corresponding to the first DNN.
The first LADN information includes DNN corresponding to the LADN which can be used by the UE in the current registration area and second service area information corresponding to DNN corresponding to the LADN.
S304, when the UE determines that the UE is located in the service area corresponding to the first DNN according to the first LADN information, the UE initiates the operation of the PDU session corresponding to the first DNN. It should be noted that the UE is located in the service area corresponding to the first DNN, which means that the UE stores the first LADN information, and the TA where the current location of the UE is located belongs to the service area corresponding to the first LADN in the first LADN information.
Wherein the initiating the PDU session corresponding to the first DNN may include: establishing the PDU session, or modifying the PDU session, or activating the user plane connection of the PDU session.
The fact that the UE is located in the service area corresponding to the first DNN means that the location of the UE (the TA in which the UE is located) is included in the service area corresponding to the first DNN.
Specifically, the operation of initiating the PDU session corresponding to the first DNN may be sending a request message for PDU session establishment/modification/activation to the first core network device, where a network name corresponding to the PDU session is the first DNN.
If the PDU session is established, modified or deleted, the first core network equipment is the SMF, namely the UE sends a request message for establishing, modifying or deleting the PDU session to the SMF through the AMF; if the PDU session is activated (the user plane connection of the PDU session is activated), the first core network device is the AMF, that is, the UE sends a request message for activating the user plane connection of the PDU session to the AMF. It should be noted that the term "activate" used in the present invention refers to activating the user plane connection (the wireless connection between the UE and the AN and the N3 connection between the AN and the UPF) for the PDU session already established, and in addition, the UE sends a message to the core network device through the AN node, and the message sent by the UE to the SMF is sent to the AMF and then forwarded to the SMF by the AMF, as shown in fig. 3, in step S304 of fig. 3, the operation of initiating the PDU session corresponding to the first DNN is exemplified by sending a request message for establishing the PDU session to the SMF through the AN and the AMF.
If the UE triggers AN application and executes steps S302 to S304, and if the UE determines that there is no PDU Session corresponding to the first DNN at present, the UE sends a Request message (PDU Session Establishment Request) for establishing the PDU Session corresponding to the first DNN to the SMF through the AN and the AMF. And if the UE triggers and establishes the user plane connection (connection between the UE and the AN and connection between the AN and the UPF) of the PDU session, sending a Service Request message (Service Request) to the AMF through the AN. If the UE triggers and modifies the PDU Session, after executing steps S302-S304, a Request message (PDU Session Establishment Request) for modifying the PDU Session is sent to the SMF through the AN and the AMF. If the UE triggers to delete (Release) the PDU Session, after executing steps S302-S304, sending a Request message (PDU Session Release Request) for deleting (releasing) the PDU Session to the SMF through the AN and the AMF
The UE acquires the first information, which may be implemented in several ways:
the first mode is as follows: the UE may obtain the first information from information preconfigured in the UE.
The second mode is as follows: and the UE receives the configuration information of the UE, wherein the configuration information comprises the first information.
The third mode is as follows: the UE receives a policy sent by a first core network device, such as an AMF or a PCF, where the policy carries the first information. Where the policy may be a URSP. If the data network indicated by the DNN comprised in the URSP is a LADN, a first indication is added to the URSP or an indication bit is added to the DNN comprised by the URSP, the indication bit comprising a second indication.
For example:
the following information may be included in the URSP:
a policy priority;
traffic descriptor:
an application identifier;
a network protocol descriptor;
non-IP descriptor；
route selection descriptor：
SSC mode selection;
selecting a network slice;
DNN selection: comprising DNN, and a first indication;
non-seamless offload indication；
access type preference。
for example, referring to fig. 4, an indication bit for indicating LADN is added in the structure of DNN. It should be noted that the indicator bit may be added to the head, tail, or any position in the middle of the DNN structure. In fig. 4, LADN is an indicator bit for indicating LAND.
For a second implementation manner of the UE to acquire the first information, specifically, before step S301, the method further includes:
s301a, the AMF sends the first information to the UE.
Optionally, before S301a, the method may include:
s301b, receives the third information sent by the PCF or SDM. Specifically, the PCF or the SDM may carry the third information in a policy or a subscription service, for example, a policy request service response, such as Npcf _ AMF policy control _ GET response, or a registration request service response, such as numdm _ SDM _ GET response.
Wherein the second information may include the first DNN and a third indication indicating that the data network indicated by the first DNN is the LADN; alternatively, the second information includes the first DNN, which includes a fourth indication indicating that the data network indicated by the first DNN is the LADN.
Optionally, in step S302, after determining that the data network indicated by the first DNN is the LADN according to the first information, and when determining that the UE does not store the first LADN information, the UE does not send a PDU session establishment/modification/deletion/request message to the SMF, and does not send a request message for activating a user plane connection to the AMF. It is understood that the UE may determine that the current location is outside the service area corresponding to the first DNN without saving the first LADN information.
It should be noted that, the UE does not send a PDU session setup/modification/deletion/request message to the core network device (AMF/SMF), which may be understood as a procedure that the UE cannot initiate PDU session setup/modification/deletion/activation of a user plane connection, or may be understood as a procedure (or process) that the UE terminates this PDU session setup/modification/deletion/activation of a user plane connection.
Optionally, in step S302, after determining that the data network indicated by the first DNN is the LADN according to the first information, if it is determined that the UE is located outside the service area corresponding to the first DNN according to the first LADN information, the UE does not send the PDU session establishment/modification/activation request message to the SMF.
Wherein determining that the UE is located outside the service area of the data network indicated by the first DNN according to the first LADN information may be implemented as follows:
if it is determined that the first LADN information does not include at least one of the first DNN and service area information corresponding to the first DNN, determining that the UE is located outside a service area of the data network indicated by the first DNN; or, if it is determined that the first LADN information includes the first DNN and service area information corresponding to the first DNN, determining that the UE is located outside the service area of the data network indicated by the first DNN according to the service area information corresponding to the first DNN.
Referring to fig. 5, optionally, in step S304, after the UE sends a request message for establishing the PDU session to the AMF when determining that the UE is located in the service area corresponding to the first DNN according to the first LADN information, the method may further include:
s305, the UE stores second information, wherein the second information is used for indicating that the data network indicated by the DNN corresponding to the PDU session is the LADN.
Thus, after saving the second information, if it is determined that the PDU session needs to be modified or activated, the method may further include:
s306, the UE determines the data network indicated by the DNN corresponding to the PDU session to be modified/activated as the LADN according to the second information. I.e. determines that the PDU session to be modified/activated is a PDU session of the LADN.
S307, the UE determines that the first LADN information includes service area information corresponding to the LADN.
S308, when the UE determines that the UE is located in the service area of the LADN according to the service area information, the UE sends a request message for activating (or modifying) the PDU session to the first core network equipment. Specifically, a service request message for activating a user plane connection of the PDU session is sent to the AMF or a PDU session modification request message for modifying the PDU is sent to the SMF through the AMF. In S308, the UE sends a request message for activating the PDU session to the AMF as an example.
Optionally, when determining that the LADN information does not include the service area information of the LADN, the UE does not send a service request message for activating a user plane connection of the PDU session to the AMF, and does not send a PDU session modification request message for modifying/deleting the PDU to the SMF; or, when the UE determines that there is no stored first LADN information, it does not send a service request message for activating a user plane connection of the PDU session to the AMF, and does not send a PDU session modification request message for modifying the PDU to the SMF.
Through the solution provided in the first embodiment, after the UE matches a DNN according to the URSP, the UE may directly know whether the data network indicated by the DNN is a LADN according to the configuration information of the UE or the URSP, so as to determine whether to perform an action of checking whether the UE is in the LADN service area. In addition, after the UE establishes the PDU session of the LADN, the information that the data network indicated by the DNN corresponding to the PDU is the LADN is stored, so that when the session is modified or the user plane connection is activated again in the following process, the data network indicated by the DNN corresponding to the PDU is determined to be the LADN directly according to the stored information, and thus whether to initiate a session establishment/modification/activation process is determined again.
Example two:
referring to fig. 6, a second possible manner will be described in detail.
A second possible way is: and all DNNs corresponding to all LADNNs subscribed by the UE are configured to the UE.
The configuration manner is the same as that of the first embodiment, and may include:
1) is preconfigured in the UE. For example, when the UE subscribes to one or more lans, DNNs of the one or more lans are configured in a Universal Subscriber Identity Module (USIM) or a Universal Integrated Circuit Card (UICC).
2) The UE is configured by a configuration device, such as a UDM or PCF. Such as over OTA technology, OMA-DM, etc.
3) The first core network equipment is configured to the UE in the process of registering the UE to the network side. For example, the core network device such as UDM, PCF, MME, AMF, or SMF configures the parameters of DNN corresponding to all LADNs subscribed by the UE, and sends the parameters to the UE through signaling.
Specifically, the method for indicating the LADN includes:
s601, UE acquires parameters, wherein the parameters comprise DNN sets of local data networks LADN signed by the UE.
It should be noted that, if there is one DNN of the LADN subscribed by the UE, the DNN set includes one DNN, and if there are multiple DNNs of the LADN subscribed by the UE, the DNN set includes multiple DNNs. Namely UE Subscribed LADN { LADN1, LADN2, … }
S602, the UE determines a first DNN.
It should be noted that the UE determines that the first DNN may be according to the URSP, that is, after the UE triggers a certain application, the UE determines that the application matches a certain rule in the URSP according to the URSP, where the rule includes the first DNN. Or, when the terminal determines that a PDU session is to be established through other methods, the DNN corresponding to the PDU session is the first DNN, and the specific method for determining the first DNN is not limited in this application.
S603, the UE determines that the set of DNNs includes the first DNN.
It is to be understood that, when the UE determines that the DNN set includes the first DNN, the UE determines that the data network indicated by the first DNN is the LADN, and further determines whether the UE is located within a service area corresponding to the first DNN; when the UE determines that the DNN set does not include the first DNN, the UE determines that the first DNN is not a DNN corresponding to the LADN, i.e., the data network indicated by the first DNN is a non-LADN. If the first DNN is not the DNN corresponding to the LADN, the UE does not need to perform the determination of whether the UE is located in the service area corresponding to the first DNN, that is, before initiating the request message for establishing, modifying, deleting, or activating the user plane connection to the core network device, the UE does not need to be determined to be located in the service area corresponding to the first DNN.
S604, the UE determines whether the UE is in the service area of the first data network, if so, performs S605, and if not, performs S606. The first data network is the data network indicated by the first DNN.
When determining whether the UE is located in the service area of the first data network, it may specifically be determined whether the UE is located in the service area of the first data network according to the first LADN information.
The first LADN information comprises a network name of the LADN which can be used by the UE in the current registration area and service area information corresponding to the network name.
And if the UE determines that the UE is outside the service area of the first data network, the UE does not send the request message for establishing/modifying/activating the user plane connection/deleting the PDU session to the first core network equipment.
If the PDU session is established, modified or deleted, the first core network equipment is the SMF, namely the UE sends a request message for establishing, modifying or deleting the PDU session to the SMF through the AMF; if the PDU session is activated (the user plane connection of the PDU session is activated), the first core network device is the AMF, that is, the UE sends a request message for activating the user plane connection of the PDU session to the AMF. S605 and S606 both have established the PDU session as an example, and the PDU session is established as an example in the following, and the implementation of other operations may refer to the implementation for establishing the PDU session.
S605, the UE sends a request message for establishing the PDU session to the SMF.
Wherein the PDU session corresponds to the first DNN.
S606, the UE does not send a request message to the SMF to establish the PDU session.
Optionally, the UE determines whether the UE is in the service area of the first data network according to the first LADN information, which may be implemented as follows:
the UE determines that the first LADN information comprises the first DNN and service area information corresponding to the first DNN, and determines whether the UE is located in a service area of the first data network according to the service area information corresponding to the first DNN; alternatively, the first and second electrodes may be,
if the UE determines that the first LADN information does not include at least one of the first DNN and service area information corresponding to the first DNN, determining that the UE is not in the service area of the first data network.
Optionally, in step S603, after determining that the DNN set includes the first DNN, if the UE determines that the first LADN information is not stored, the UE determines that the UE is located outside a service area of the first LADN, and does not send a request message for establishing/modifying/activating a PDU session to the SMF.
The UE may obtain the parameters in several ways: for the configuration of the specific parameter, reference may be made to the above description for the configuration, and details are not described here.
The first mode is as follows: the UE may obtain the parameters from information pre-configured at the UE.
The second mode is as follows: and the UE receives the configuration information of the UE, wherein the configuration information comprises the parameters.
The third mode is as follows: receiving a registration acceptance message sent by the AMF, wherein the registration acceptance message comprises the parameters; or receiving a configuration update message sent by the AMF, wherein the configuration update message comprises the parameters.
Referring to fig. 7, a flowchart of a third implementation manner of obtaining parameters by the UE is shown, taking the example of including the parameters in the registration accept message.
S701, the UE sends a registration request (registration request) message to the AMF through the AN.
S702, after receiving the registration request message, the AMF sends a registration request service, such as numm-UECM _ registration, to the UDM.
S703, the UDM sends a registration request service response to the AMF, e.g. Nudm _ SDM _ GET, which includes the DNN of the LADN to which the UE has subscribed. The DNN of the LADN to which the UE subscribes may be one or more.
S704, the AMF sends a policy request service, e.g. Npcf _ AMF policy control _ GET,
s705, the PCF sends a policy request service response, e.g., Npcf _ AMF policy control _ GET response, to the AMF.
The AMF sends a registration accept (registration accept) message to the UE S706. Wherein the registration acceptance message includes a DNN corresponding to the LADN subscribed by the UE. Optionally, the registration acceptance message may further include the first LAND information.
By the scheme provided in the second embodiment, after the UE matches the DNN corresponding to the triggered application according to the URSP, whether the data network indicated by the DNN is a LADN may be known through the DNN corresponding to the saved signed LADN, so as to determine whether to execute an action of checking whether the UE is in a service area of the LADN. Thereby saving signaling resources to some extent. In addition, the success rate of initiating the process of establishing/modifying/activating the session is improved.
With respect to the first embodiment: the UE obtains all signed LADN DNN, and can directly inquire whether the data network indicated by DNN corresponding to the session is LADN when the session is established, modified or activated. In the first embodiment, after the UE knows that the data network indicated by the DNN is an LADN from the URSP, the UE needs to mark the corresponding PDU session with the LADN. Because the subsequent modification or activation of the session will not determine through the URSP that the data network indicated by the DNN is a LADN.
Example three:
referring to fig. 8, a third possible way is specifically described.
A third possible way is: a new way of configuring the LADN information is proposed, and for convenience of description, the LADN information configured by this way is referred to as second LADN information.
The second LANN information comprises a DNN set of LANNs signed by the UE and service area information corresponding to DNNs of the LANNs which can be used by the UE in the current registration area in the DNN set; the LADN that the UE can use in the current registration area is located in the registration area of the UE. The second LANN information does not include service area information corresponding to DNN of the LANN which cannot be used by the UE in the DNN set.
For example: the DNNs of the LADNs to which the UE subscribes include DNN1, DNN2, and DNN 3. The network names of the LADN that the UE can use in the current registration area include DNN1 and DNN 2. For DNN3, the service area corresponding to DNN3 is not in the registration area of the UE or the AMF is not configured with the LADN of DNN3, so that the UE cannot use the current registration area, and the service area information of DNN3 is not included in the second LADN information. The second LADN information includes the following: service area information corresponding to DNN1 and DNN 1; service area information corresponding to DNN2 and DNN 2; DNN 3. Specifically, the following format can be expressed: the second LADN information { [ DNN1, DNN1-Service Area ], [ DNN2, DNN2-Service Area ], [ DNN3] }. It should be noted that the second LADN information does not include the service area information of DNN3, that is, does not include any TA information, and specifically, the service area information corresponding to DNN3 may be null, that is, the content of the field indicating the service area information corresponding to DNN3 is set to null, or the field indicating the service area information corresponding to DNN3 may be default.
S801, the UE acquires second LADN information.
The UE acquires the second LADN information, which may be implemented as follows: receiving a registration acceptance message sent by the AMF, wherein the registration acceptance message comprises the parameters; or receiving a configuration update message sent by the AMF, wherein the configuration update message comprises the parameters. It is to be understood that the AMF needs to generate the second LADN information before sending the registration receipt message or the configuration update message including the second LADN information to the UE.
S802, the UE determines a first DNN.
It should be noted that the UE determines that the first DNN may be according to the URSP, that is, when the UE triggers an application, the UE determines a rule that the application is matched to the URSP according to the URSP, where the rule includes the first DNN, or when the terminal determines that a PDU session is to be established through other methods, a DNN corresponding to the PDU session is the first DNN, and the specific method for determining the first DNN is not limited in this application.
S803, the UE determines that the second LADN information includes the first DNN.
It can be understood that, when the UE determines that the second LADN information includes the first DNN, the UE determines that the data network indicated by the first DNN is the LADN, and further needs to perform the determination of whether the UE is in the service area corresponding to the first DNN; when the UE determines that the second LADN information does not include the first DNN, the UE determines that the first DNN is not a DNN corresponding to the LADN, and does not need to perform the determination of whether the UE is in the service area corresponding to the first DNN.
S804, the UE determines whether the second LADN information includes service area information corresponding to the first DNN. If so, go to S805, otherwise go to S806.
S805, the UE determines whether the UE is located in the service area of the first data network indicated by the first DNN according to the service area information corresponding to the first DNN; if so, go to step S807, otherwise, go to step S806.
And if the UE determines that the UE is outside the service area of the first data network, the UE does not send the request message for establishing/modifying/activating the user plane connection/deleting the PDU session to the first core network equipment.
If the PDU session is established, modified or deleted, the first core network equipment is the SMF, namely the UE sends a request message for establishing, modifying or deleting the PDU session to the SMF through the AMF; if the PDU session is activated (the user plane connection of the PDU session is activated), the first core network device is the AMF, that is, the UE sends a request message for activating the user plane connection of the PDU session to the AMF. S806 and S807 take the establishment of the PDU session as an example, and then take the establishment of the PDU session as an example, the implementation of other operations may refer to the implementation of establishing the PDU session.
S806, the UE does not send a request message to the SMF to establish the PDU session.
S807, UE sends a request message for establishing PDU session to SMF; wherein the PDU session corresponds to the first DNN.
Optionally, after step S803, if it is determined that the second LADN information does not include the first DNN, the request message is not sent to the SMF.
Referring to fig. 9, a flowchart of an implementation manner for acquiring the second LADN information for the UE is shown, taking the example that the registration acceptance message includes the parameter.
S901, the UE sends a registration request (registration request) message to the AMF through the AN.
S902, after receiving the registration request message, the AMF sends a registration request service, e.g., numm-UECM _ registration, to the UDM.
S903, the UDM sends a registration request service response to the AMF, e.g., Nudm _ SDM _ GET, which includes the DNN of the LADN to which the UE has subscribed. The DNN of the LADN to which the UE subscribes may be one or more.
And the AMF determines second LADN information according to the LADN signed by the UE, the LADN condition configured by the AMF, the position of the UE and the like. S904, the AMF sends a policy request service, e.g., Npcf _ AMF policy control _ GET,
s905, the PCF sends a policy request service response, e.g. Npcf _ AMF policy control _ GET response, to the AMF.
S906, the AMF sends a registration accept (registration accept) message to the UE. Wherein the registration acceptance message includes the second LAND information.
By the scheme provided in the third embodiment, after the UE obtains the DNN included in the matched URSP rule according to the application, it can know whether the data network indicated by the DNN is a LADN or not by obtaining the second LAND information, so as to determine whether to execute an action of checking whether the UE is in a LADN service area or not. Thereby saving signaling resources to some extent. In addition, the success rate of initiating the process of establishing/modifying/activating the session is improved.
Relative to example two: the UE acquires all signed LADN DNN of the UE through the LADN information, and can directly inquire the second LADN information to determine whether the data network indicated by the DNN corresponding to the session is the LADN and whether the UE is located in the corresponding service area when the session is established, modified or activated. In the second embodiment, the first LADN information needs to be configured to the UE, and also all subscribed LADNs of the UE need to be additionally configured, and the UE needs to determine that a DNN corresponding to the session is a LADN through all the configured subscribed LADNs, and then determine whether the UE is located in the corresponding service area through the first LADN. Thereby saving overhead compared to the second embodiment.
