It should be understood that the terms "system" and "network" are often used interchangeably herein.

Currently, a common terminal device may perform data service transmission through a public network (i.e., PLMN). However, in some scenarios, such as an office scenario, a home scenario, or a factory, a local user or administrator will typically deploy the NPN network in order to enable more effective and secure management.

The NPN Network includes a Public Network Integrated NPN (PNI-NPN) Network and an independent Non-Public Network (SNPN) Network.

The PNI-NPN Network is a private Network supporting private use of a Public Land Mobile Network (PLMN), that is, a private Network service is provided using a Public PLMN. SNPN is a private network of a non-3 GPP public network, i.e., a particular subject, such as a factory operator, uses the private network to reserve PLMNs for serving the private network. Wherein, the PNI-NPN is also called a Closed Access Group (CAG).

As shown in fig. 2, one NPN network may serve other networks. The other network may be a third party Service Provider (SP), or may be a PLMN network, or may be a third party subscription or certificate Provider. In this scenario, the terminal device may discover other networks and may connect to other networks for related communications through the NPN network.

In some particular scenarios, a single entity may connect multiple NPN networks simultaneously. Referring to fig. 3, in fig. 3, the NPN1 network and the NPN2 network support SP1 at the same time. In this case, the terminal device may move from the NPN1 network to the NPN2 network. However, when a plurality of NPN networks are simultaneously connected to a single entity, how a terminal device is connected from one of the plurality of NPN networks to another of the plurality of NPN networks has not been specified yet.

In view of this, the present invention provides a method for wireless communication, which can effectively implement the movement of a terminal device from one NPN network to another NPN network of a plurality of NPN networks when a single entity is simultaneously connected to the plurality of NPN networks.

The method described in fig. 6 may be applied to a separate entity (which may be, for example, SP1 in fig. 3). As shown in fig. 6, the method 400 may include at least some of the following.

In 410, the individual entity receives a request message sent by the source core network device, where the request message is used to request to switch the connection between the terminal device and the source network to the connection between the terminal device and the target network.

In 510, the terminal device receives first information sent by a source access network device, where the first information is used to instruct the terminal device to switch from a source network to a target cell of a target network.

In 520, the terminal device switches from the source network into the target cell based on the first information.

The source network and the target network are NPN networks, and the source network and the target network are simultaneously connected with a single entity.

It should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The method of wireless communication according to the embodiments of the present application will be further described with reference to fig. 4-7. It is to be understood that the following description applies to both the method 200 and the method 300-500.

It should be understood that the above mentioned switching of the terminal device from the source NPN network to the target NPN network can also be expressed as: the terminal device moves from the source NPN network to the target NPN network.

In order to more clearly describe the technical solutions of the embodiments of the present application, the following detailed description is made in conjunction with three embodiments.

Example 1

The technical solution of embodiment 1 may be applied to a scenario where there is no interface between the target NPN network and the source NPN network. At this time, the context information of the terminal device may be forwarded through a separate entity providing the service.

As shown in fig. 8, the specific steps of the technical solution of the embodiment 1 are as follows:

step 1: and the source Access Network equipment, namely a source Radio Access Network (S-RAN), sends the measurement configuration information of the measurement target NPN Network to the terminal equipment.

Specifically, the measurement configuration information may include, but is not limited to, frequency point information where the target NPN network is located and/or cell information of the target NPN network, and further include individual entity information supported by the target NPN network.

Step 2: and the terminal equipment performs cell measurement and reports the measurement result to the source access network equipment based on the measurement configuration information.

The measurement result may include target cell information, and the target cell information may include, but is not limited to, at least one of the following: the frequency point and Physical Cell Identity (PCI) of the target Cell, the Identity of the target Cell, and the index of the target Cell.

Optionally, the measurement report may further include information of the first individual entity supported by the target cell.

Alternatively, the first individual entity information may not be included in the measurement report. The terminal device may determine the first individual entity information of the relevant connection in a process of establishing the connection, for example, in a signaling interaction through a Radio Resource Control (RRC) layer or through a Non-access stratum (NAS) layer.

Specifically, the terminal device may notify the source access network device of the first individual entity information in the RRC connection setup procedure, or

The source core network device may obtain information of an individual entity to which a connection established by the terminal device belongs, in a NAS interaction process with the terminal device. For example, the source core network device may acquire the single entity information in a registration process, a service establishment process, or a Protocol Data Unit (PDU) session connection establishment process. Then, the source core network device may provide the individual entity information to which the context of the terminal device belongs to the source access network device in the terminal device context establishment process.

Alternatively, the terminal device may report only cell information capable of supporting the information of the individual entity to the source access network device.

And step 3: the source access network device sends a request message to a core network device of the source NPN, namely a source AMF (S-AMF) entity, according to the measurement report reported by the terminal device, wherein the request message is used for requesting to switch the connection between the terminal device and the source NPN to the connection between the terminal device and the target network.

The request message may include context information of the terminal device and also include target cell information.

Optionally, the source access network device may further determine whether to allow the terminal device to switch to the target NPN network. The specific judgment method may be as follows: the source access network equipment acquires the first authorization information through the source AMF entity, and then, the source access network equipment judges whether the terminal equipment is allowed to be switched to the target NPN network or not according to the first authorization information, or judges whether the terminal equipment is allowed to be authorized to be switched to the target NPN network or not, or judges whether the terminal equipment is authorized to be switched to the target NPN network in the supported single entity service or not. The individual entity service may be, but is not limited to: and performing voice and emergency call services by using the PLMN network.

And 4, step 4: after receiving the request message, the source AMF entity may determine the individual entity according to the target cell information and/or the first individual entity information. The source AMF entity may then forward the request message, which may include context information of the terminal device and target cell information, to a separate entity.

Optionally, the request message may also carry identification information of the source NPN network and identification information of the terminal device, and the like.

In addition, the source AMF entity may obtain a Session Management (SM) context of the terminal device through the SMF, and then the source AMF entity may carry the SM context of the terminal device in the request message.

Optionally, the source AMF entity may also determine whether to allow the terminal device to handover to the target NPN network.

Further, the source AMF entity may obtain an AMF entity of the target NPN network, that is, a target AMF (T-AMF) entity, according to the target cell information and/or the first individual entity information.

And 5: after receiving the request message sent by the source AMF entity, the single entity determines a network entity which needs to forward the context information of the terminal equipment.

Specifically, if the request message sent by the source AMF entity to the separate entity includes information indicating the target AMF, the separate entity may send the request message to the target AMF entity, i.e., forward the context information of the terminal device to the target AMF entity. If the request message sent by the source AMF entity to the separate entity does not include the information indicating the target AMF entity, the separate entity may determine the target AMF entity according to the target cell information included in the request message sent by the source AMF entity to the separate entity. The individual entity may then forward the request message to the target AMF entity.

The request message sent by the separate entity may include target cell information and identification information of the terminal device.

It should be understood that the information for indicating the AMF entity may indicate the target AMF entity, or may implicitly indicate the target AM entity F, which is not specifically limited in this embodiment of the application.

Alternatively, the separate entity may also determine whether to allow the terminal device to switch to the target NPN network. Specifically, the individual entity may obtain, by the source AMF entity, third authorization information, where the third authorization information is used to indicate whether to authorize the terminal device to access the target NPN network, or whether to allow the terminal device to be switched to the target NPN network, or whether to authorize the terminal device to be switched to the target NPN network in the supported individual entity service.

Step 6: the target AMF entity establishes a context for the SM.

Further, if the SMF entity is not changed, i.e. the source SMF entity and the target SMF entity are the same, the address of the terminal device may not be updated. If the SMF entity is changed, the address of the terminal device needs to be updated.

And 7: and the target AMF entity determines target access network equipment (T-RAN) according to the received target cell information.

The target AMF entity may then forward the request message to the target access network device.

And 8: the target access network equipment is ready for switching resources and returns confirmation information to the target AMF entity, namely, a request response message is sent to the target AMF entity.

The request response message may include context information of the terminal device and handover configuration information determined by the target access network device.

And step 9: the target AMF entity forwards the request response message sent by the target access network equipment to the single entity.

Step 10: and after receiving the request response message, the individual entity forwards the request response message to the source AMF entity.

Step 11: and after receiving the request response message, the source AMF entity forwards the request response message to the source access network equipment.

Step 12: after receiving the request response message, the source access network device may determine that the terminal device may be switched from the source NPN network to the target NPN network, and then the source access network device may send switching information to the terminal device, where the switching information is used to instruct the terminal device to switch from the source NPN network to a target cell of the target NPN network.

As can be seen from the technical solution of embodiment 1, when a single entity is simultaneously connected to a plurality of NPN networks, the technical solution of embodiment 1 can implement movement of a terminal device from one NPN network to another NPN network in the plurality of NPN networks, that is, movement from a source NPN network to a target NPN network can be implemented, and service continuity of the terminal device can be implemented without any interface between the source NPN network and the target NPN network.

Example 2

The technical solution of embodiment 2 may be applied to a scenario where an interface exists between a source AMF entity and a target AMF entity. As shown in fig. 9, the specific steps of the technical solution of the embodiment 2 are as follows:

step 1: and the source access network equipment sends the measurement configuration information of the measurement target NPN network to the terminal equipment.

And step 3: the source access network equipment sends a request message to the source AMF entity.

And 4, step 4: after receiving the request message, the source AMF entity determines a target AMF entity according to the target cell information and/or the first single entity information, and then the source AMF entity sends the request message to the target AMF entity.

The request message may include context information of the terminal device and target cell information.

And 5: the target AMF entity establishes the context of the AMF.

Step 6: and the target AMF entity determines the target access network equipment according to the received target cell information. The target AMF entity may then forward the request message to the target access network device.

And 7: the target access network equipment is ready for switching resources and returns confirmation information to the target AMF entity, namely, a request response message is sent to the target AMF entity.

And 8: and the target AMF entity forwards the request response message sent by the target access network equipment to the source AMF entity.

And step 9: and after receiving the request response message, the source AMF entity forwards the request response message to the source access network equipment.

Step 10: after the source access network device receives the request response message, it is confirmed that the terminal device can be switched from the source NPN network to the target NPN network, and then the source access network device can send switching information to the terminal device.

As can be seen from the technical solution of embodiment 2, when a single entity is simultaneously connected to a plurality of NPN networks, the technical solution of embodiment 2 can implement movement of a terminal device from one NPN network to another NPN network in the plurality of NPN networks, that is, can implement movement from a source NPN network to a target NPN network, and service continuity of the terminal can be implemented between the source NPN network and the target NPN network only in a scenario where an interface exists in a core network device.

Example 3:

the technical solution of embodiment 3 may be applied to a scenario where there is an interface between the source access network device and the target access network device. As shown in fig. 10, the specific steps of the technical solution of the embodiment 3 are as follows:

And step 3: and the source access network equipment judges whether the terminal equipment is allowed to be switched to the target NPN network. If the terminal device is allowed to switch from the source NPN network to the target NPN network, the source access network device may send a request message to the target access network device.

And 4, step 4: the target access network equipment is ready for switching resources, and returns confirmation information to the source access network equipment, namely, sends a request response message to the source access network equipment.

Before step 4, the target access network device may further determine whether to allow the terminal device to switch from the source NPN network to the target NPN network. Specifically, the target access network device may obtain, by the target AMF entity, second authorization information, where the second authorization information is used to indicate whether to authorize the terminal device to access the target NPN network, or whether to allow the terminal device to switch to the target NPN network, or whether to authorize the terminal device to switch to the target NPN network in the supported individual entity service.

And 5: after the source access network device receives the request response message, it is confirmed that the terminal device can be switched from the source NPN network to the target NPN network, and then the source access network device can send switching information to the terminal device.

As can be seen from the technical solution of embodiment 3, when a single entity is simultaneously connected to a plurality of NPN networks, the technical solution of embodiment 3 may implement mobile movement of a terminal device from one NPN network to another NPN network in the plurality of NPN networks, that is, may implement movement from a source NPN network to a target NPN network, and in addition, an interface exists between the source NPN network and the target NPN network in an access network device, and service continuity of the terminal device may be implemented in a scenario where the source NPN network and the target NPN network share a core network.

It should be understood that although embodiments 1-3 are described above separately, this does not mean that embodiments 1-3 are independent and that the descriptions of the various embodiments may be referred to one another. For example, the description related to embodiment 1 can be applied to embodiment 2 and embodiment 3.
