And the opposite end user equipment transmission related business. However, the high-level user equipment does not know which network environment the peer user equipment is in, and can only randomly select a certain access method to try, and it may take multiple attempts to restore the business with the peer user equipment, which will cause comparison. Big time delay.

As shown in FIG. 2, this exemplary embodiment provides a method for determining an access mode, which can be applied to a first user equipment of wireless communication, and the method includes:

Step 101: Receive access indication information through a direct link, where the access indication information is used to indicate one or more alternative access methods that can be used.

The first user equipment and the second user equipment may be two user equipments in a state of being connected to each other. For example, the first user equipment may establish a connection with the second user equipment through a direct link or the like.

The second user equipment may send its currently available access mode to the first user equipment in the form of the first candidate access mode information. Wherein, the currently available access mode of the second user equipment itself may be an access mode through a Uu port and/or an access mode through a PC5. The currently available access mode of the second user equipment may be used by the first user equipment to select the target access mode for access.

Exemplarily, the second user equipment may determine whether the Uu port is available according to whether it currently resides in the cellular communication network; the second user equipment may determine whether the Uu port is available according to whether it supports the direct connection and whether the transmission resources of the direct connection can be obtained To determine whether the current direct link is available.

When the currently available access mode of the second user equipment itself changes, the access indication information may be sent to update the access mode.

Exemplarily, when the direct link between the first device and the second device fails, the first user equipment may select a target access mode from an alternative access mode according to the access indication information to perform link reestablishment. The selected target access mode can be any alternative access mode. The direct link can be preferentially selected as the target access mode. In this way, the negotiation process of the connection between the first device and the second device can be simplified.

In this way, the first user equipment determines the access mode that can be used to establish a connection with the second user equipment according to the access indication information, and then can select the access mode to establish a connection with the second user equipment, thereby reducing invalid connection attempts, thereby The time delay for establishing a connection with the second user equipment is reduced, and the connection efficiency is improved.

In an embodiment, the method for determining an access mode further includes: selecting a target access mode that meets the access requirement from one or more alternative access modes that can be used, and establishing a connection with the second user equipment.

The access requirement may be determined according to the transmission service between the first user equipment and the second user equipment. Different transmission services between the first user equipment and the second user equipment have different access requirements. The access requirements can be determined according to the type of transmission service, and the access requirements can be selected according to the access requirements among the alternative access methods. The target access method.

The first user equipment may select a target access mode to establish a connection with the second user equipment when the preset condition is met. Satisfying the preset condition may be determined according to the current connection status between the first user equipment and the second user equipment. For example, when the current connection between the current first user equipment and the second user equipment cannot meet the transmission service requirement or the connection fails, it is determined that the preset condition is satisfied. For example: when the current connection between the first user equipment and the second user equipment fails, the target access mode may be selected to establish a connection with the second user equipment.

In one embodiment, the method for determining the access mode further includes: receiving the device identifier of the second user equipment through the direct link; step 101 includes: establishing the connection with the second user equipment in the target access mode based on the device identifier of the second user equipment. 2. Connection of user equipment.

When the first user equipment and the second user equipment establish a direct link, the first user equipment and the second user equipment exchange their respective device identifiers through high-level signaling during the mutual discovery process. The device identification can be used to uniquely identify the user equipment during the establishment of the direct link.

In the case where the first user equipment fails in the current direct link connection, the first user equipment needs to continue the unfinished transmission service with the second user equipment. The first user equipment may re-establish a connection with the second user equipment in a target access mode based on the equipment identification of the second user equipment.

In an embodiment, the device identification includes: a direct link layer 2 identification.

The direct link layer 2 identification can uniquely identify the second user equipment in the direct link. In the process of mutual discovery of the first user equipment and the second user equipment, the first user equipment may obtain the direct link layer 2 identifier of the second user equipment. Exemplarily, the first user equipment currently establishes a connection with the second user equipment through an NR direct link unicast connection. The target access mode selected by the first user equipment is an access mode accessed through an LTE direct link. When a radio link failure occurs in the access mode through the NR direct link, the first user equipment can find the second user equipment again through the LTE direct link based on the direct link layer 2 identification of the second user equipment, and The connection is established to complete the communication service with the second user equipment.

In one embodiment, step 101 includes: selecting a target access method that meets the access requirement and can be used by the first user equipment from one or more available alternative access methods.

If the target access method is an access method through a Uu port, the first user equipment and the second user equipment may use different cellular mobile communication technologies. For example, the first user equipment adopts 4G cellular mobile communication technology, and the second user equipment adopts 5G cellular mobile communication technology, and the first user equipment and the second user equipment may interact through a base station.

If the target access mode is the direct link access mode, the first user equipment and the second user equipment need to adopt the same direct link access mode. For example, alternative access methods include: access through 5G (ie, new air interface NR) direct link access. If the first user equipment supports the access method through NR direct link, it can Determine the access method through the NR direct link as the target access method. Otherwise, because the first user equipment cannot establish a connection through the NR direct link access method, it cannot be connected through the NR direct link. The access mode for link access is determined as the target access mode.

In an embodiment, selecting a target access mode that meets the access requirement includes: selecting a target access mode that meets the QoS requirements of the transmission service.

Different transmission services have different requirements for QoS, and the first user equipment can select an access mode that meets the QoS of the current transmission service among the alternative access modes for access.

Exemplarily, the alternative access methods that can be used by the second user equipment include: an access method through an LTE air interface and an access method through an LTE direct link. The transmission service between the first user equipment and the second user equipment is an Internet of Vehicles business, and the corresponding access requirements for the Internet of Vehicles business include: the QoS requirement is a delay of 10 ms and a rate of 10 Mb/s. In this way, for this access requirement, among the alternative access modes, the access mode that meets the access requirements is the access mode through the LTE direct link. Therefore, the access mode that the first user equipment can select may be through The access method of LTE direct link access.

In one embodiment, step 101 includes:

The access instruction information contained in the wireless command is received through the direct link.

The second user equipment may carry the access instruction information in the wireless instruction, and use the currently connected direct link to send the wireless instruction. In one embodiment, receiving the access indication information contained in the wireless command via the direct link includes:

Receive the access indication information contained in the PC5 radio resource control RRC command through the direct link.

The second user equipment may send an RRC instruction to the first user equipment through the PC5 interface of the direct link with the first user equipment, and the RRC instruction carries the access indication information. The first user equipment receives the access indication information included in the RRC instruction sent by the second user equipment through the PC5 interface.

In an embodiment, the alternative access method includes at least one of the following: access method through LTE Uu port; access method through NR Uu port; access method through LTE direct link ; Access method through NR direct link; access method through non-terrestrial network (NTN, Non-Terrestrial Network).

The second UE can determine whether the access mode through the LTE Uu port, the access mode through the NR Uu port, and the access mode through the NTN network according to whether it is camped on the LTE, NR, or NTN network. Available access methods.

The second UE may determine whether it has the ability to access through the LTE direct link and through the NR direct link, and whether it can obtain the available direct link radio resources to determine whether it is accessed through the LTE direct link. Whether the access mode and the access mode accessed through the NR direct link are available access modes.

Similarly, the first user equipment may send its currently available access mode to the second user equipment by sending the second candidate access mode information. Wherein, the currently available access mode of the second user equipment itself may be an access mode through an air Uu port and/or an access mode through a PC5. When the direct connection between the first user equipment and the second user equipment fails, the second user equipment may select the access mode indicated in the second alternative access mode information to initiate a connection with the first user equipment. The first and second user equipment initiates the connection with the first device, which is similar to the manner in which the first user equipment initiates the access to the second device, and will not be repeated here.

A specific example is provided below in conjunction with any of the foregoing embodiments:

The specific steps of the interaction between the first UE and the second UE are shown in Figure 3 and include:

Step 301: After the first UE establishes the direct link unicast connection, it sends the available access mode to the opposite second UE through the PC5RRC message, indicating that the available access mode for the first UE includes at least one of the following: The access method of LTE Uu port access; the access method of NR Uu port; the access method of LTE direct link; the access method of NR direct link; the access method of NTN Access method.

In step 301, the first UE can determine the access mode through the LTE Uu port according to whether it camps on the LTE, NR or NTN network; the access mode through the NR Uu port and the access mode through the NTN access Whether the access mode is an available access mode.

In step 301, the first UE may determine the access through the LTE direct link according to whether it has the capabilities of the LTE direct link and the NR direct link and whether it can obtain the available direct link radio resources. Mode and whether the access mode accessed through the NR direct link is an available access mode.

Step 302: When the available access mode of the first UE is changed, the first UE needs to send a PC5RRC message to the second UE at the opposite end to update the available access mode.

Step 303: After the first UE receives the access mode that can be used for the transmission service sent by the second UE, it sends the direct link layer 2 identifier of the second UE and the transmission service access mode available for the second UE to the second UE. A UE high-level.

Step 304: When the direct link unicast connection fails between the first UE and the second UE, the first UE higher layer selects a new access mode for the service from the access modes available to the second UE, and instructs the connection Enter the layer for access.

Exemplary:

The UE1 high-level instructs the access layer to use the NR direct link to send the Internet of Vehicles service to UE2. The QoS requirement of the Internet of Vehicles service is a delay of 10ms and a rate of 10Mb/s.

The access layer of UE1 establishes an access mode of access via NR direct link unicast connection with UE2 according to the high-level instruction, which is used to transmit the Internet of Vehicles service to UE2.

UE2 currently resides on the LTE network, and the available access methods for UE2 include access through the LTE Uu port; UE2 has LTE direct link capability and NR direct link capability, and the LTE network provides LTE and NR direct link capabilities. Link wireless resources. Therefore, UE2 can send a PC5 RRC message to UE1, which carries available access methods including: access through LTE Uu port, access through LTE direct link, and through NR direct link. The access method of incoming.

After UE1 receives the PC5RRC message sent by UE2, the access layer identifies the direct link layer 2 of UE2 and the access method through the LTE Uu port, the access method through the LTE direct link and the access method through NR The three access methods of direct link access are reported to the higher layer.

When the direct link unicast connection between UE1 and UE2 has a radio link failure, the upper layer of UE1 judges that the service can only be accessed through the LTE direct link and through the NR Uu port according to the QoS requirements of the Internet of Vehicles service. The access mode transmission can meet the requirements, and UE2 supports the access mode through the LTE direct link, but does not support the access mode through the NR Uu port, then the transmission technology of this service is changed to The access mode accessed through the LTE direct link is then indicated to the access layer.

The access layer of UE1 establishes a connection with UE2 and continues the Internet of Vehicles business by using the access method of NR Uu port access according to the instructions of the higher layers.
