Description

Background Art

[0002] With the continuous development of 5G communication technology, 5G ProSe (Proximity Services) technology has gradually become a research hotspot. 5G ProSe technology allows user equipment (UE) to communicate directly without going through the core network, thereby improving communication efficiency and reducing communication latency. In 5G ProSe technology, the discovery of relay devices (i.e., user equipment that connects remote devices to the network through relays) is a key link.

[0003] At present, the discovery of relay devices is a direct discovery method, that is, the remote device simultaneously initiates a relay discovery request message to multiple relay devices (such as 5G ProSe UE to network relay), and then these relay devices return relay discovery response messages to the remote device respectively. However, this direct discovery method has a certain problem of wasting network resources. Specifically, when the remote device initiates a relay discovery request, it establishes multiple communication paths at the same time, but in the actual communication process, only one of the communication paths will be selected for communication, and the remaining communication paths will be abandoned, resulting in a waste of network resources.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0037] For ease of understanding, before introducing the embodiments of the present disclosure, several terms involved in the embodiments of the present disclosure are first explained as follows:

[0038] ProSe: Proximity Service, near-domain service, is a device-to-device (D2D) connection or direct communication between nearby mobile devices defined in 3GPP TS23.303 R12 version. In this communication mode, the user equipment (UE) can send and receive data directly in the uplink spectrum without forwarding through network infrastructure such as base stations.

[0039] RSC: Relay Service Code, a relay service code, is an identifier applicable to communication from a user device to a network relay device, or from a user device to a relay device. In the TS 23.303 v18.3.0 document, communication from a user device to a network relay device is defined. For communication from a user device to a relay device, the relay service code is used to identify the connection service provided by the relay device in the near-field communication scenario and the authorized user to whom the relay device will provide the service.

[0040] Remote device: A user device that supports near-field communication and can access the target network or communicate with other remote devices through a relay device.

[0041] Relay device: A relay user device or network relay device that supports near-area communications and can provide relay services. It can receive messages from remote devices and forward them to other remote devices or the network infrastructure of the target network.

[0042] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

Figure 1 As shown, the system architecture includes: a remote device 10, a relay discovery scheduling center 20 and at least one relay device (such as Figure 1 ); a first relay device 30A, a second relay device 30B and a third relay device 30C shown in FIG.

When the UE-to-network relay discovery process is started, the 5G ProSe relay scheduling center searches for an adapted relay according to the RSC in the received request message, and searches for the most adapted UE-to-network relay through the previous 5G ProSe UE-to-network relay discovery or through the strength of the secure PC5 connection signal between the 5G ProSe UE-to-network relay and the 5G ProSe remote UE.

[0047] By implementing the method of UE-to-network relay discovery through relay scheduling provided in the embodiments of the present disclosure, the problem of resource waste caused by the device initiating multiple communication paths at the same time can be avoided, and the 5G ProSe relay scheduling center can select the best UE-to-network relay, that is, discover the most suitable 5G ProSe UE-to-network relay with the least resources.

[0048] In some embodiments, the above-mentioned network connection information includes at least: signal strength; then the above-mentioned relay discovery scheduling center 20 is also used to: select the relay device with the largest signal strength from one or more relay devices that the remote device can connect to according to the signal strength from each relay device to the target network, and determine it as the target relay device that meets the conditions.

[0051] In some embodiments, the relay discovery scheduling center 20 is also used to store relay service codes of multiple relay devices and network connection information of each relay device to the target network, wherein the relay service code of each relay device is used to identify one or more remote devices authorized by the relay device to use the relay service.

[0052] It should be noted that the remote device in the embodiment of the present disclosure refers to a user device that cannot directly access the target network (such as a cellular network); the relay device refers to a user device that can directly access the target network (such as a cellular network). In the embodiment of the present disclosure, the relay device can access the target network through a wireless network or a wired network.

The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network).

[0057] Figure 2 A flowchart of directly discovering a relay in a near-field communication scenario in the related art is shown. Figure 2 As shown, specifically including:

[0058] S202: The remote device sends a relay discovery request message to multiple relay devices.

[0059] Taking 5G ProSe as an example, a 5G ProSe remote UE sends a 5G ProSe UE to network relay discovery request message. The 5G ProSe UE to network discovery request message contains the discovery message type, discoverer information, RSC and optional target information. The 5G ProSe remote UE discovering the 5G ProSe UE to network relay sends a request message with an RSC associated with the desired connection service.

[0060] S204: The remote device receives a relay discovery response message returned by each relay device.

[0061] Taking 5G ProSe as an example, if the RSC contained in the request message matches any (pre-)configured RSC of the 5G ProSe UE to network relay, and the target information (if any) contained in the request message matches the 5G ProSe UE to network relay, the 5G ProSe UE to network relay (e.g. 1, 2 and 3) responds to the 5G ProSe remote UE with a UE to network relay discovery response message. The 5G ProSe UE to network relay discovery response message contains the discovery message type, discovery information and RSC.

[0062] S206: Select a relay device for near area communication.

[0063] Taking 5G ProSe as an example, the 5G ProSe remote UE selects the 5G ProSe UE to the network relay according to the relay discovery response message returned by each relay device received in S204.

[0064] Figure 3 A flowchart of performing relay discovery through a relay discovery scheduling center in a near-field communication scenario in an embodiment of the present disclosure is shown. Figure 3 As shown, specifically including:

[0065] S300, the relay discovery scheduling center pre-stores the relay service codes of all relay devices, previous discovery of the remote device to the relay device, and the network connection information between the relay device and the remote device.

[0066] Taking 5G ProSe as an example, a 5G ProSe relay scheduling center is added to the 5G ProSe UE to network relay discovery process, and all UE to network relay RSCs, previous 5G ProSe UE to network relay discoveries, and secure PC5 connection information between 5G ProSe UE to network relay and 5G ProSe remote UE are pre-stored in it.

[0067] S302: The remote device sends a relay discovery request message to the relay discovery scheduling center.

[0068] Taking 5G ProSe as an example, the discoverer 5G ProSe remote UE sends a UE to network relay discovery request message to the 5G ProSe relay scheduling center. The 5G ProSe UE to network relay discovery request message includes the discovery message type, RSC and direct discovery set, including the user information ID of the discoverer 5G ProSe remote UE.

[0069] S304, the relay discovery dispatch center searches for the most suitable relay device.

[0070] Taking 5G ProSe as an example, the 5G ProSe relay scheduling center searches for an adapted 5G ProSe UE to network relay according to the RSC in the received UE to network relay discovery request message, and searches for the most adapted UE to network relay through previous 5G ProSe UE to network relay discovery or through the strength of the secure PC5 connection signal between the 5G ProSe UE to network relay and the 5G ProSe remote UE.

[0071] S306: The relay discovery scheduling center forwards the relay discovery request message to the target relay device.

[0072] Taking 5G ProSe as an example, the 5G ProSe relay scheduling center sends a UE to network relay discovery request message to the selected most suitable 5G ProSe UE to network relay (e.g., 5G ProSe UE to network relay-3). The 5G ProSe UE to network relay discovery request message contains a direct discovery set, which includes the user information ID of the discoverer 5G ProSe remote UE and the RSC of the UE to network relay.

[0073] S308, the target relay device returns a relay discovery response message.

[0074] Taking 5G ProSe as an example, the 5G ProSe UE to network relay-3 returns a UE to network relay discovery response message to the 5G ProSe remote UE.

[0075] Figure 4A schematic diagram showing the complexity of a direct discovery relay in the related art is shown. Figure 5 A schematic diagram showing the complexity of performing relay discovery through a relay discovery scheduling center in an embodiment of the present disclosure is shown, and compared with Figure 4 and Figure 5 It can be seen that the complexity of the direct discovery process of the relay is 2N; the complexity of the relay discovery through the relay discovery scheduling center is 3. When the number of 5G ProSe UE to network relays exceeds 1, the embodiment of the present disclosure can significantly reduce the complexity of the 5G ProSe UE to network relay discovery process, and can effectively avoid resource waste without increasing the time consumption of the relay discovery process.

[0076] The near-area communication method provided in the embodiment of the present disclosure is applied to 5G ProSe, and a 5G ProSe relay scheduling center is added on the terminal side, and all RSCs of UE to network relays, previous 5G ProSe UE to network relay discovery, and secure PC5 connection information between 5G ProSe UE to network relay and 5G ProSe remote UE are pre-stored therein. When the UE to network relay discovery process is started, the 5G ProSe relay scheduling center searches for an adapted relay according to the RSC in the received 5G ProSe UE to network relay discovery request message, and searches for the most adapted UE to network relay through the previous 5G ProSe UE to network relay discovery or through the strength of the secure PC5 connection signal between the 5G ProSe UE to network relay and the 5G ProSe remote UE.

[0090] It should be noted that after determining the target relay device that meets the conditions, the relay discovery request message initiated by the remote device can be forwarded to the target relay device. When the target relay device returns a relay discovery response message to the remote device, the remote device conducts near-field communication with the target relay device.

[0091] In some embodiments, Figure 7 As shown, before searching for one or more relay devices to which the remote device can connect according to the relay service code included in the relay discovery request message and obtaining network connection information of each relay device to the target network, the near area communication method provided in the embodiment of the present disclosure may further include the following steps:

[0092] S600, storing relay service codes of multiple relay devices and network connection information of each relay device to a target network, wherein the relay service code of each relay device is used to identify one or more remote devices authorized by the relay device to use relay services.

[0093] It should be noted that the relay service code of each relay device and the network connection information of each relay device to the target network can be collected in advance, and as the near-field communication is subsequently established, the stored relay service code of each relay device and the network connection information of each relay device to the target network can be continuously updated, for example, deleting unavailable relay network connections, or updating the status information of the relay network connection, or adding new relay network connections for near-field communication.

[0094] From the above, it can be seen that the near-field communication method provided in the embodiment of the present disclosure, by adding a relay discovery scheduling center on the terminal side, after receiving the relay discovery request message initiated by the remote device, searches for one or more relay devices that the remote device can connect to according to the relay service code contained in the relay discovery request message, and then obtains the network connection information of each relay device to the target network. According to the network connection information of each relay device to the target network, a target relay device that meets the conditions is selected from the one or more relay devices that the remote device can connect to, and the relay discovery request message initiated by the remote device is forwarded to the target relay device, so that the target relay device returns a relay discovery response message to the remote device.

[0095] Through the near-field communication method provided in the embodiments of the present invention, it is possible to find the most suitable relay device at the moment according to the relay discovery request message initiated by the remote device, and establish near-field communication with the relay device. This can avoid the problem of network resource waste in the traditional near-field communication process, in which the remote device simultaneously initiates the communication process of relay discovery to multiple relay devices.

[0096] In some embodiments, the above network connection information includes at least: signal strength; then the above S206 can be implemented through the following steps: according to the signal strength from each relay device to the target network, select the relay device with the largest signal strength from one or more relay devices that the remote device can connect to, and determine it as the target relay device that meets the conditions.

[0097] In this embodiment, the signal strength may be the signal strength of the network connection from each relay device to the target network, and / or the signal strength of the network connection from the remote device to each relay device.

[0098] In some embodiments, the above-mentioned relay discovery request message also includes: the message type of the near-field communication message; the above-mentioned network connection information also includes: the message type of the relay service provided by the relay device; then the above-mentioned S606 can be implemented through the following steps: according to the message type of the near-field communication message and the message type of the relay service provided by each relay device, select one or more relay devices that meet the corresponding message type from one or more relay devices that the remote device can connect to; according to the signal strength from each relay device to the target network, select the relay device with the largest signal strength from the one or more relay devices that meet the corresponding message type, and determine it as the target relay device that meets the conditions.

[0099] In the above embodiment, when the relay discovery request message contains the message type when the remote device performs near-field communication, one or more relay devices that meet the corresponding message type can be selected from one or more relay devices to which the remote device can connect, and then the relay device with the largest signal strength can be selected.

[0100] In some embodiments, the relay discovery request message further includes: user information of the remote device; Figure 8 As shown, the near area communication method provided in the embodiment of the present disclosure can also obtain the network connection information of each relay device to the target network through the following steps:

[0101] S802, according to the relay service code included in the relay discovery request message, searching for one or more relay devices to which the remote device can connect, and obtaining the relay service code of each relay device, wherein the relay service code of each relay device is used to identify one or more remote devices authorized by the relay device to use the relay service;

[0102] S804, based on the user information of the remote device contained in the relay discovery request message and the relay service code of each relay device, screening one or more relay devices that authorize the remote device to use the relay service from the one or more relay devices to which the remote device can connect;

[0103] S806, obtaining network connection information from each relay device that authorizes the remote device to use the relay service to the target network.

[0104] It should be noted that, for security reasons, some relay devices may only allow authorized user devices to access. Therefore, when the relay discovery request message contains user information of the remote device, it can be determined whether the remote device is a user device authorized by the relay device. Through the above embodiment, it can be ensured that the remote device accesses the relay device that authorizes it to access, avoids unauthorized user devices from accessing the relay device, and improves the security of near-field communication.
