Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The present disclosure proposes a communication method for establishing a user plane data link for a UE of a private network, described below in connection with fig. 1-3.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S114.
In step S102, the access network receives a first registration request sent by a UE of the private network.
The UE sends a first registration request to AN access network ((R) AN), which may be composed of network elements such as a base station. The first registration request may include: UE identity, network slice identity.
In step S104, the access network identifies the UE as a private network according to the UE identifier, and determines AMF, SMF, and UPF corresponding to the network slice according to the network slice identifier.
In some embodiments, one or more corresponding network slices are preset for the UE of the private network, and access networks, AMFs, SMFs and UPFs corresponding to the network slices are determined; for each network slice, configuring the corresponding relation of the identification of the UE, the identification of the network slice, the AMF, the SMF and the UPF in the access network corresponding to the network slice, and configuring the corresponding relation of the identification of the UE and the identification of the network slice in the UPF corresponding to the network slice.
The private network UE can configure a corresponding private network slice, and the access network determines whether the UE is the UE of a private network according to the comparison result of the identification of the UE and the identification of the locally configured private network UE. And further, corresponding AMF, SMF and UPF can be determined according to the identification of the network slice.
In step S106, the access network sends a second registration request to the AMF.
And if the access network determines the AMF corresponding to the network slice, the access network directly sends a second registration request to the AMF, and the AMF selection process is not required to be executed. The second registration request may include: UE identity, network slice identity.
In step S108, the AMF confirms that the UE is provided with service.
In some embodiments, before step S108, further comprising: in step S107, the AMF sends a UE identity authentication request to the AUSF (authentication service function) and completes the authentication procedure with the UE. As shown in fig. 2, the AMF interacts with the AUSF through an N12 interface. In case the authentication passes, the AMF sends a subscription data query request to the UDM (unified data management platform), e.g. interacting through an N8 interface. Wherein the subscription data query request includes: an identification of the UE, an identification of the network slice; the AMF receives a subscription data query response returned by the UDM, wherein the subscription data query response comprises information of whether the network slice is an authorized network slice corresponding to the UE; in the case that the network slice is an authorized network slice corresponding to the UE, the AMF confirms that the UE is provided with service.
The procedure of the AMF and the UE for identity authentication may refer to the existing standard, and will not be described herein. The UDM may store an identification of a corresponding one or more network slices formulated in advance for the UE, and whether each network slice is currently in an authorized state. For example, assume that the identities of the network slices are customized for the UE in advance as a and B, and the two network slices correspond to the monitoring function and the management signaling function, respectively. If the UE needs to temporarily turn off the monitoring function (the function of network slice a), the configuration of network elements such as (R) AN need not be changed, but subscription slice a is cancelled or modified to AN unauthorized state in the UDM. When the UE requests the slice A, the AMF discovers that the subscription information of the slice A is not available in the UDM or the slice A is in an unauthorized state, and the registration request of the UE is refused.
In step S110, the SMF and UPF corresponding to the network slice establish a session.
In some embodiments, the SMF receives a session establishment indication sent by the UDM, wherein the session establishment indication comprises: the identification of the UPF is determined by the UDM according to the identification of the network slice; the SMF establishes an N4 session with the UPF, activates the context of the UE to the UPF through an N4 interface, and the context of the UE comprises: the identification of the UE, the identification of the network slice.
After receiving the subscription data query request sent by the AMF, the UDM may determine, according to the identifier of the network slice, the SMF and the UPF corresponding to the network slice. As shown in fig. 2, the UDM may interact with the SMF through the N10 interface, and the SMF may establish an N4 session with the UPF through the N4 interface and activate the context of the UE. The specific session establishment procedure and context activation procedure may refer to existing standards, and will not be described in detail herein.
In step S112, the access network receives a registration success message returned by the AMF.
In step S114, the access network establishes a connection with the UPF.
After confirming that the UE is served, the AMF may return a registration success message to the access network. The access network receives the registration success message returned by the AMF, and can activate the identification of the UE and the identification of the network slice according to the registration success message. The access network is configured with the UPF corresponding to the network slice, so that the access network can directly establish connection with the UPF, and compared with the prior art, the process of establishing the GTP-U tunnel is omitted. As shown in fig. 2, the (R) AN interacts with the UPF through AN N3 interface.
In the above embodiment, for the UE of the private network, the first registration request sent by the UE carries the identifier of the UE and the identifier of the network slice, the access network identifies the UE as the UE of the private network according to the identifier of the UE, directly determines the AMF, the SMF and the UPF corresponding to the network slice according to the identifier of the network slice, does not need to perform the selection process of the AMF, the SMF and the UPF, directly confirms by the AMF corresponding to the network slice to provide services for the UE, and establishes a session by the SMF and the UPF corresponding to the network slice, and the access network directly establishes connection with the UPF when receiving the registration success message returned by the AMF. The scheme of the embodiment simplifies the selection process of network elements such as AMF, SMF, UPF in the communication process, omits the establishment process of a GTP-U tunnel, reduces the signaling overhead in the access process, is suitable for private network environment, simplifies the core network, and enables the terminal with opposite morphology and service of the IoT terminal to be more immobilized and determined, thereby facilitating the establishment of a data channel between the IoT terminal device and the private network, improving the establishment efficiency of a user plane data link, realizing the efficient data distribution of the private network, improving the communication quality, and meeting the requirements of industrial enterprises on the communication quality.
Further embodiments of the disclosed communication method are described below in conjunction with fig. 3.
Fig. 3 is a flow chart of other embodiments of the disclosed communication method. As shown in fig. 3, the method of this embodiment includes: steps S302 to S324.
In step S302, one or more corresponding network slices are preset for the UE, and access networks, AMFs, SMFs, and UPFs corresponding to the network slices are determined, and QoS policies are preset for the UE, for each network slice, first slice instance information and QoS policies are configured in the access network corresponding to the network slice,
the QoS policy may include: priority of each network slice. The QoS policy may be different for each UE, or may be different for the traffic of the private network, and may specifically be configured according to actual requirements.
In step S304, for each network slice, the second slice instance information and QoS policy are configured at the UPF corresponding to the network slice.
The first slice instance information includes, for example: the identity of the UE, the identity of the network slice, the correspondence of AMF, SMF and UPF. The second slice instance information includes, for example: the identity of the UE, the identity of the network slice. The UPF may not have to configure the AMF, SMF, and UPF corresponding to the network slice.
In some embodiments, qoS policies may be sent to access networks and UPFs corresponding to respective network slices of the UE by UDM or PCF (policy control function), without requiring advanced configuration.
In step S306, the access network receives a first registration request sent by a UE of the private network.
In step S308, the access network identifies the UE as a private network according to the UE identifier, determines an AMF corresponding to the network slice according to the network slice identifier, and sends a second registration request to the AMF.
In step S310, the AMF confirms that the UE is provided with service.
In step S312, the SMF and UPF corresponding to the network slice establish a session.
The SMF establishes an N4 session with the UPF, and the SMF activates the UE's context (including but not limited to the UE's identity, the network slice's identity) to the private network UPF through N4. Establishing an N4 session retains control of the UPF function by the SMF. The SMF does not need to acquire GTP-U TEID (Tunnel Endpoint Identifier, tunnel endpoint identification) information, etc. through the N4 session to establish the data plane management QoS flow in this step, because the UPF corresponding to each network slice is already configured with priority.
In step S314, the access network receives a registration success message returned by the AMF.
In step S316, the access network establishes a connection with the UPF.
In step S318, the access network receives a data packet sent by the UE, where the data packet includes: the identification of the UE and the identification of the network slice are matched with the context of the UE according to the identification of the UE and the identification of the network slice, and the QoS strategy corresponding to the UE is searched.
In step S320, the access network executes QoS policies and sends a data packet to the UPF, where the data packet includes: the identity of the UE and the identity of the network slice.
In step S322, the UPF matches the context of the UE according to the UE identity and the network slice identity, and searches for the QoS policy corresponding to the UE.
In step S324, the UPF enforces the QoS policy and forwards the packet.
The UPF sends a packet to a DN (Data Network), for example.
