First, some terms in the present application are explained so as to be easily understood by those skilled in the art.

1. VMR application scenario: as shown in fig. 2, the VMR application scenario in the network sharing scenario is as follows: a Public Land Mobile Network (PLMN) supported by the terminal device 1 is assumed to be PLMN a; the terminal device 2 supports PLMN B, the VMR supports PLMN a and PLMN B, and the network device supports PLMN a and PLMN B, so the specific requirements that the terminal device 1 and the terminal device 2 can be connected to networks of different PLMNs through the same VMR are as follows:

1) The 5G system may support Radio Access Network (RAN) sharing capability of the VMR, where the VMR broadcasts a shared PLMN(s) and the terminal device may connect to different PLMN core networks.

2) The 3GPP system may support actively connected UE end-to-end service continuity, which may be specifically in the following cases: when a UE changes between a shared mobile relay RAN (e.g., in-vehicle) and a fixed RAN (e.g., out-of-vehicle), or between different PLMNs through RAN sharing of the (same) mobile relay (e.g., inside a vehicle, when spanning geographic areas with different sharing protocols and/or configurations).

2. Radio access network sharing (RAN sharing): in order to deal with the problems of high spectrum license cost, network deployment cost, pressure for providing higher network coverage requirement in a short term limit, and site deployment challenge, the concept of network sharing is proposed. RAN sharing refers to that a radio access network is shared by multiple operators, and further, RAN sharing is divided into a multi-operator core network (MOCN) and a gateway core network (GWCN) according to whether core network devices are shared, where an architecture diagram of the MOCN is shown in fig. 3, an architecture diagram of the GWCN is shown in fig. 4, and the two are the same: the shared carrier frequency sharing and the sub-carrier frequency sharing of the RAN are supported; the difference is as follows: MOCN core networks are not shared, and the core networks of operators are independent; and the GWCN part is shared by core network elements.

The sharing mode of the radio access network mainly includes 3 forms: shared carrier frequency sharing, sub-carrier frequency sharing and mixed carrier frequency sharing.

The schematic diagram of common carrier frequency sharing is shown in fig. 5, and the schematic diagram of sub-carrier frequency sharing is shown in fig. 6, which are specifically explained as follows:

1) Shared carrier frequency refers to RAN resources, including spectrum resources and base station hardware resources, shared among multiple operators. The method comprises the steps that a plurality of operators share the same cell, and a plurality of PLMN identification (PLMN) identification numbers (IDs) are broadcasted in the shared cell, wherein the PLMNs comprise the PLMN ID of a main operator and the PLMN IDs of a plurality of slave operators.

2) The sub-carrier frequency sharing means that base stations are shared among different operators, but cells are not shared, and only one PLMN ID is broadcast by each cell. The cells used by different operators are independent.

3) The hybrid carrier frequency sharing refers to that operators share base station hardware resources, and share or individually share frequency spectrum resources. The operator broadcasts a plurality of PLMN IDs in the cell, including the PLMN ID of one main operator and the PLMN IDs of a plurality of slave operators, and the PLMN IDs of the main operators of the cells may not be consistent.

For the sharing of the common carrier frequency of the MOCN, the resource sharing modes among different PLMNs have the following forms:

1) And (3) full sharing: resources are completely shared, each PLMN is based on competition access, and the implementation is simple.

2) Static proportion sharing: the RRC connection number is distributed to different PLMNs according to a fixed proportion, the fairness is good, but the resource utilization rate is not high.

3) Dynamic proportional sharing: the method has the advantages that the method is shared in proportion, when the resource of one PLMN is idle, the method can be used by other PLMNs, is suitable for Radio Bearer (RB) resources, and is high in resource utilization rate and guaranteed in fairness;

the existing RAN sharing mechanism mainly aims at an application scenario under a single fixed network device, and the LTE RN mechanism does not involve relay mobility, and as shown in fig. 2, when there is no network device that meets the conditions near the relay node, that is, there is no network device that supports the same shared PLMN as the relay node near the relay node, how to implement the shared service of the relay node is a technical problem that those in the art are solving. In order to solve the above problem, the embodiments of the present application propose the following solutions.

Referring to fig. 7, fig. 7 is a communication processing method in a network sharing scenario according to an embodiment of the present application, where the method includes, but is not limited to the following steps:

step S701: the core network equipment acquires the capability information of the relay node.

Specifically, the relay node may be a relay UE in a D2D scenario, or may be a VMR. The capability information includes at least two PLMNs supported by the relay node. In one example, assuming two PLMNs of the relay node, the identification information of the two PLMNs is PLMN a and PLMN B, the capability information includes PLMN a and PLMN B.

Optionally, the capability information further includes second indication information, where the second indication information is used to indicate that the air interface resource of the relay node supports being shared by the RAN. Wherein, since the second indication information is used to indicate that the air interface resource of the relay node is supported by RAN for sharing, the relay node supports at least two PLMNs. If the capability information includes third indication information, where the third indication information is used to indicate that the air interface resource of the relay node does not support sharing by the RAN, the number of types of PLMNs supported by the relay node is less than 2, and the operation in step S701 is not executed.

Specifically, when the capability information does not include the second indication information or the third indication information, the core network device may determine, indirectly according to the capability information, that the air interface resource of the relay node is supported by the RAN for sharing. That is to say, according to whether the number of the types of PLMNs supported by the relay node included in the capability information is greater than or equal to 2, when the number of the types of PLMNs supported by the relay node included in the capability information is greater than or equal to 2, it is determined that the air interface resource of the relay node is supported by the RAN for sharing; and when the number of the types of the PLMNs supported by the relay node in the capability information is less than 2, determining that the air interface resources of the relay node are not supported to be shared by the RAN.

Specifically, the core network device may obtain the capability information of the relay node in the following two ways: the first mode is as follows: the core network device receives a non-access stratum (NAS) message from the relay node, the NAS message including capability information. The second mode is as follows: the core network device obtains subscription information of the relay node stored in the core network, wherein the subscription information comprises capability information. The storage of the core network may refer to storage in Unified Data Management (UDM), or storage in a local subscriber server (HSS), and the like.

Step S702: and the core network equipment determines a second host node sharing the air interface resource of the relay node with the first host node according to the capability information.

In particular, the first host node and the second host node support at least one of at least two PLMNs. In an example, it is assumed that the relay node supports two PLMNs, identification information of the two PLMNs is PLMN a and PLMN B, identification information of a PLMN supported by the first host node is PLMN a, and identification information of a PLMN supported by the second host node is PLMN B. In yet another example, it is assumed that the relay node supports two PLMNs, the identification information of the two PLMNs is PLMN a and PLMN B, the identification information of the PLMN supported by the first host node is PLMN a and PLMN C, and the identification information of the PLMN supported by the second host node is PLMN B and PLMN C.

Specifically, the first host node and the second host node provide communication services of different PLMNs to the air interface of the relay node at the same time. In an example, assuming that the identification information of the PLMNs supported by the relay node is PLMN a and PLMN B, the identification information of the PLMN supported by the first host node is PLMN a, and the identification information of the PLMN supported by the second host node is PLMN B, the first host node provides a communication service of PLMN a for the air interface of the relay node, and meanwhile, the second host node provides a communication service of PLMN B for the air interface of the relay node.

Specifically, the air interface resource is configured by the network device to the relay node, and is used for the relay node to communicate with the terminal device. The terminal device can be a terminal device supporting single card and single standby, and can also be a terminal device supporting double card and double standby. Among them, the resource for the relay node to communicate with the first host node and the second host node is called a backhaul (backhaul) resource.

Specifically, the core network device may determine, according to the capability information, that the second host node shares an air interface resource of the relay node with the first host node, by using the following method: the first host node broadcasts the self-supported PLMNs in a broadcasting mode, the relay node randomly accesses the first host node, reports the self-supported at least two PLMNs to the core network equipment through the first host node, and the core network equipment determines a second host node according to at least one of the at least two PLMNs supported by the first host node, the at least two PLMNs supported by the relay node and the PLMNs supported by the network equipment adjacent to the first host node.

In an example, it is assumed that a relay node supports two PLMNs, identification information of the two PLMNs is PLMN a and PLMN B, and identification information of a PLMN supported by a first host node is PLMN a and PLMN C, the first host node broadcasts identification information of the PLMN supported by itself in a broadcast manner to be PLMN a and PLMN C, the relay node randomly accesses the first host node, reports the identification information of the two PLMNs supported by itself to a core network device through the first host node to be PLMN a and PLMN C, and the core network device determines, according to the identification information of the PLMN supported by the first host node, that the identification information of the PLMN supported PLMN is PLMN a and PLMN C, the identification information of the two PLMNs supported by the relay node is PLMN a and PLMN B, and the PLMN supported by a network device adjacent to the first host node, that the identification information of the supported PLMN is a second host node including PLMN B.

Step S703: the core network equipment sends first indication information to the first host node.

Specifically, the first indication information includes identification information of the second host node. The identification information of the second hosting node may be identification information of a plurality of second hosting nodes.

Specifically, the first indication information may further include identification information of PLMNs supported by the second donor node, or the first indication information includes an indication field for indicating PLMNs supported by the second donor node. In one example, assuming that the identification information of the PLMN supported by the second host node is PLMN B, the first indication information may further include PLMN B.

Step S704: the first host node receives first indication information from the core network device.

Step S705: the first host node sends a request message to the second host node.

Specifically, the request message is used to request the second donor node to provide a communication service for the relay node. The request message is used to request the second host node to provide a communication service for the relay node, that is, after the second host node agrees with the request message, the relay node adds the second host node, and then the first host node and the second host node allocate air interface resources belonging to different PLMNs for the relay node, thereby realizing sharing of the air interface resources of the relay node among different PLMNs. Optionally, the request message includes indication information, where the indication information is used to indicate air interface resource sharing of different PLMNs between the first host node and the second host node. The request message may include identification information of PLMNs supported by the first host node. Assuming that the identification information of the PLMN supported by the first host node is PLMN a, the request message includes PLMN a.

Specifically, the request message may further include first air interface resource configuration information of a PLMN supported by the first host node and the relay node. The first air interface resource configuration information is used for determining air interface resources of the shared relay node. The first air interface resource configuration information includes a Radio Resource Control (RRC) connection number under a PLMN provided by the first host node for the air interface of the relay node, a Resource Block (RB) ratio under the PLMN provided by the first host node for the air interface of the relay node, a Protocol Data Unit (PDU) session number under the PLMN provided by the first host node for the air interface of the relay node, and a terminal device maximum access number under the PLMN provided by the first host node for the air interface of the relay node.

In an example, assuming that the identification information of the PLMN supported by the first host node is PLMN a and the identification information of the PLMN supported by the relay node is PLMN a and PLMN B, the identification information of the PLMN supported by both the first host node and the relay node is PLMN a. The identifier information of the PLMN provided by the first host node for the air interface of the relay node is PLMN a, and the first configuration information includes the RRC connection number under PLMN a, the RB ratio under PLMN a, the maximum PDU session number under PLMN a, and the maximum access number of the terminal device under PLMN a.

Step S706: the second host node receives the request message from the first host node.

Step S707: the second host node sends a first acknowledgement message to the first host node.

Specifically, the first acknowledgement message may include the first air interface resource configuration information after the first host node and the second host node coordinate. That is to say, the second host node may modify the first air interface resource configuration information sent by the first host node, and then carry the modified first air interface resource configuration information through the first acknowledgement message.

Step S708: the first host node receives a first acknowledgement message from the second host node.

Step S709: and the second host node sends second air interface resource configuration information under the PLMN commonly supported by the second host node and the relay node to the first host node.

Specifically, the second air interface resource configuration information is used to determine an air interface resource of the shared relay node. The second air interface resource configuration information includes: the number of RRC connections under the PLMN provided by the second host node for the air interface of the relay node, the RB proportion under the PLMN provided by the second host node for the air interface of the relay node, the number of PDU sessions under the PLMN provided by the second host node for the air interface of the relay node, and the maximum number of terminal equipment accesses under the PLMN provided by the second host node for the air interface of the relay node.

In one example, assuming that the identification information of the PLMN supported by the second donor node is PLMN B and the identification information of the PLMN supported by the relay node is PLMN a and PLMN B, the identification information of the PLMN supported by both the second donor node and the relay node is PLMN B. The identifier information of the PLMN provided by the second donor node for the air interface of the relay node is PLMN B, and the second configuration information includes the RRC connection number under PLMN B, the RB ratio under PLMN B, the maximum PDU session number under PLMN B, and the maximum access number of the terminal device under PLMN B.

Step S710: and the first host node receives second air interface resource configuration information under the PLMN jointly supported by a second host node and the relay node from the second host node.

Step S711: the first host node sends a second acknowledgement message to the second host node.

Specifically, the second acknowledgement message may include second air interface resource configuration information after the first host node and the second host node coordinate. That is to say, the first host node may modify the second air interface resource configuration information sent by the second host node, and then carry the modified second air interface resource configuration information through the second confirmation message.

Step S712: the second host node receives a second acknowledgement message from the first host node.

Step S713: and the first host node configures the air interface resource shared in the relay node for the relay node according to the first air interface resource configuration information and the second air interface resource configuration information.

Specifically, the form in which the first host node configures the air interface resource shared in the relay node for the relay node may be shown in table 1.

Table 1

Step S714: and the relay node randomly accesses the second host node.

Step S715: the relay node starts to operate in the RAN ringing mode.

In the method, when the network device which supports the same shared PLMN as the relay node does not exist near the relay node, the capability information of the relay node can be obtained through the core network device, the second host node is determined according to the capability information, and the first indication information is sent to the first host node, so that the first host node and the second host node can provide communication services of different PLMNs for an air interface of the relay node, that is, the relay node is connected into the first host node and the second host node which provide the communication services of different PLMNs, so that the terminal device can be connected to networks of different PLMNs through the relay node, the cost of network deployment is reduced, and when the network device which supports the same shared PLMN as the relay node does not exist near the relay node, the shared service of the relay node is realized.

step S801: the first host node acquires the capability information of the relay node.

In particular, the capability information includes at least two PLMNs supported by the relay node. In one example, the capability information includes two PLMNs supported by the relay node, and the identification information of the two PLMNs is PLMN a and PLMN B.

Specifically, the first host node may obtain the capability information of the relay node in the following two ways: the first host node receives a NAS message from the relay node, the NAS message including capability information. The second mode is as follows: the first host node receives capability information from the core network device, where the capability information may be reported to the relay node by the terminal device, the relay node sends the capability information to the first host node, the first host node forwards the capability information to the core network device, and the core network device sends the capability information to the first host node. The capability information may also be subscription information of the relay node, which is obtained by the core network device and stored in the core network, where the subscription information includes the capability information.

Step S802: and the first host node determines a second host node sharing the air interface resource of the relay node with the first host node according to the capability information.

In particular, the first host node and the second host node simultaneously provide communication services of different PLMNs for the air interface of the relay node.

Specifically, the air interface resource is configured to the relay node by the network device, and is used for the relay node to communicate with the terminal device. The terminal equipment can be terminal equipment supporting single card and single standby, and can also be terminal equipment supporting double card and double standby. The resources between the relay node and the first host node and the second host node are called backhaul (backhaul) resources.

Specifically, the first host node may determine, according to the capability information, that the second host node shares an air interface resource of the relay node with the first host node, by: the first host node broadcasts the PLMNs supported by the first host node in a broadcasting mode, the relay node randomly accesses the first host node and reports the capability information to the first host node, and the corresponding first host node determines a second host node according to at least one of the at least two PLMNs supported by the first host node and the at least two PLMNs supported by the relay node.

In an example, it is assumed that a relay node supports two PLMNs, identification information of the two PLMNs is PLMN a and PLMN B, and identification information of a PLMN supported by a first host node is PLMN a and PLMN C, the first host node broadcasts identification information of the PLMN supported by itself in a broadcast manner to be PLMN a and PLMN C, the relay node randomly accesses the first host node and reports capability information to the first host node, the capability information includes identification information of the two PLMNs supported by itself to be PLMN a and PLMN C, and the first host node determines, for PLMN a and PLMN B, identification information of the supported PLMN to be a second host node including PLMN B according to the identification information of the PLMN supported by itself and the identification information of the two PLMNs supported by the relay node.
