It should be noted that features of the embodiments of the invention and of the different embodiments may be combined with each other without conflict.
The inventor of the present invention has encountered in practice that the related art of relay discovery based on proximity service has a problem of unreasonable relay selection, which is reflected in that the selected relay cannot provide an accurate network service.
The present inventors have continued to research and find that, in the related art, the relay discovery mechanism only uses limited local parameters, and in this case, when the remote ue performs processing based on the relay selection algorithm, due to the limitation of required information, the selected relay cannot provide high-quality network service.
Therefore, the present inventors have determined that the limitation of parameter information is one of the reasons for the low accuracy of relay discovery in the related art.
Based on the reasons discovered by the inventor of the present disclosure, the embodiments of the present disclosure provide a relay discovery scheme, and an inventive idea thereof is that a relay user equipment obtains network information of itself from a core network, and sends a relay discovery announcement message to a remote user equipment based on the network information. In this case, the remote user equipment can obtain richer parameter information of the relay user equipment, so that the relay user equipment can be selected more accurately, and the relay discovery accuracy is improved, so that the remote user equipment can obtain higher-quality network service.
Fig. 1 is an architecture diagram of a relay discovery system according to an embodiment of the present disclosure, and as shown in fig. 1, the relay discovery system includes a relay user equipment 1a and a core network 1b, which are capable of establishing a communication connection therebetween.
Among them, the relay user equipment 1a is a user equipment capable of providing a relay service.
The function of the core network 1a is mainly to provide user connection, user management and service-implemented bearer, and to provide an interface to an external network as a bearer network, because it processes and distributes services of the whole network, it is usually in a relatively high platform position and in a more core position with respect to the underlying network, and is therefore called the core network.
Fig. 2 is a timing diagram of a relay discovery method based on a relay discovery system according to an embodiment of the present disclosure, and the following describes specific functions of the relay user equipment 1a and the core network 1b in the relay discovery system shown in fig. 1 with reference to fig. 2.
As shown in fig. 2, the relay discovery method may include the following steps:
step 210: the relay user equipment 1a sends a network information acquisition request carrying a relay user equipment identifier to a core network 1 b;
step 220: the core network 1b receives a network information acquisition request carrying a relay user equipment identifier from the relay user equipment 1a, responds to the network information acquisition request, and acquires the network information of the relay user equipment 1a according to the relay user equipment identifier;
step 230: the relay user equipment 1a sends response information to the relay user equipment 1a according to the acquired network information;
step 240: the relay user equipment 1a receives response information of the network information acquisition request from the core network 1b, and extracts the network information of the relay user equipment from the response information;
step 250: the relay UE 1a sends relay discovery announcement messages to remote UEs UE-1, UE-2 and UE-3 based on the network information.
In this case, each of the remote UEs UE-1, UE-2 and UE-3 processes the relay advertisement message based on the relay selection algorithm to determine whether to select the relay UE 1a for network connection.
As shown in fig. 3, the relay UE communicates with the core network to obtain network information, and also communicates with the remote UE to broadcast the relay discovery advertisement message.
By using the embodiment of the disclosure, the remote user equipment can obtain richer parameter information of the relay user equipment, so that the relay user equipment can be more accurately matched, and the relay discovery accuracy is improved, so that the remote user equipment can obtain higher-quality network service.
In the embodiment of the present disclosure, the core network may be configured with a relay policy control network element entity, and the core network processes the specific network information acquisition request through the relay policy control network element entity. Specifically, the relay policy control network element entity is specifically configured to:
responding to the network information acquisition request, sending corresponding parameter request messages to other network element entities of the core network based on the relay user equipment identification, receiving parameter response messages of the other network element entities, acquiring corresponding parameter information from the parameter response messages, and acquiring network information according to the parameter information.
Therefore, the feasibility of the scheme is improved by adding a relay strategy control network element entity in the core network.
With this embodiment, different network element entities have different functions, and therefore different network element entities provide different parameter information, and therefore, the relay policy control network element entity requests specific parameter information from other network element entities, and obtains network information by summarizing the information, and responds the network information to the relay user equipment.
The network element entity is a certain network element or node in a network system, and can independently complete equipment with one or more functions, and the core network realizes the opening of specific network control capability, monitoring capability, network information, basic network service capability and the like through the network element entity.

And the remote user equipment judges whether the relay user equipment is a relay node for providing the relay network connection according to the subscription information.
In the core network, the other network element entities may include, but are not limited to, AMF (Access and Mobility Management Function), SMF (Session Management Function), and UPF (User Plane Function). The network element entities contained in the core networks may be different and may be selected according to the needs.
In this embodiment of the present disclosure, the relay policy control network element entity may also locally query corresponding parameter information based on the relay user equipment identifier. If the relay strategy control network element entity stores a plurality of parameter information, the relay strategy control network element entity can directly respond to the relay user equipment.

In this case, the relay user equipment serves as a relay node, providing a relay network service, through which the remote user equipment can communicate with other user equipments.
In this embodiment of the present disclosure, before the relay user equipment sends the relay discovery announcement message, the relay user equipment may also locally obtain a local parameter of the relay user equipment, and send the relay discovery announcement message to the remote user equipment based on the local parameter and the network information when the local parameter of the relay user equipment is obtained.
Compared with the related art, the embodiment of the disclosure expands the information content of the relay discovery announcement message on the basis of the local parameter of the relay user equipment, so as to improve the relay discovery accuracy. Compared with the related technology, the scheme solves the problem that the remote user equipment flexibly and accurately selects the required network information parameters from a plurality of relay user equipment.
