[0027] The method for determining the layer 2 identifier provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0028] like Figure 2 As shown, one embodiment of the present invention provides a method 200 for determining a Layer 2 identifier. This method can be executed by a terminal device; in other words, it can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0029] S202: The first terminal determines the destination layer 2 identifier of the relay additional discovery information based on the target information.

[0030] The target information includes one of the following: the Layer 2 identifier of the relay additional discovery information configured in the target configuration information; the source Layer 2 identifier of the first terminal obtained in the target process before obtaining the relay additional information; and the source Layer 2 identifier of the second terminal obtained in the target process before obtaining the relay additional information.

[0031] The first terminal is one of a relay terminal and a remote terminal, and the second terminal is the other of the relay terminal and the remote terminal.

[0032] Optionally, the target configuration information mentioned above may include policy parameters. The target configuration information may be configured by the network side, or it may be pre-configured in the Universal Subscriber Identity Module (USIM) or Mobile Equipment (ME) of the first terminal. In one implementation, during the process of obtaining additional relay discovery information, the relay terminal and the remote terminal use the configured L2 ID as the target L2 ID for the additional relay discovery information.

[0033] In another implementation, the relay terminal and the remote terminal determine the target L2 ID for additional relay discovery information based on the source Layer 2 identifier of the peer terminal during the relay discovery process. For example, this could be the source Layer 2 identifier of the first terminal obtained during the target process prior to acquiring additional relay information; or the source Layer 2 identifier of the second terminal obtained during the target process prior to acquiring additional relay information. The target process may include: a relay discovery process, a cell identifier broadcast process, or a unicast establishment process, etc.

[0034] This invention provides a method for determining a Layer 2 identifier. By determining the target Layer 2 identifier of relay additional discovery information based on target information, the target information includes one of the following: the Layer 2 identifier of the relay additional discovery information configured in target configuration information; the source Layer 2 identifier of a first terminal obtained during the target process before obtaining the relay additional information; and the source Layer 2 identifier of a second terminal obtained during the target process before obtaining the relay additional information. The first terminal is one of a relay terminal and a remote terminal, and the second terminal is the other of the relay terminal and the remote terminal. This method solves the problem that during the process of obtaining relay terminal additional information, the relay terminal cannot determine the target Layer 2 identifier of the relay discovery additional information, which may cause the remote terminal to fail to accurately receive the relay additional information.

[0035] like Figure 3As shown, one embodiment of the present invention provides a method 300 for determining a layer 2 identifier. This method can be executed by a terminal device; in other words, it can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0036] S302: When the first terminal is a relay terminal, the Layer 2 identifier of the relay additional discovery information configured in the target configuration information is used as the destination Layer 2 identifier; the relay discovery additional information is sent through the destination Layer 2 identifier.

[0037] The target information includes a Layer 2 identifier for the relay additional discovery information configured in the target configuration information. The source Layer 2 identifier for the relay discovery additional information is generated by the first terminal and / or the second terminal.

[0038] The remote terminal uses the Layer 2 identifier of the relay additional discovery information configured in the target configuration information as the destination Layer 2 identifier; and listens for the relay discovery additional information according to the destination Layer 2 identifier.

[0039] Optionally, the first terminal may also receive a relay discovery additional information reply sent by the second terminal. The relay discovery additional information reply uses the Layer 2 identifier of the relay additional discovery information configured in the target configuration information as the destination Layer 2 identifier.

[0040] Correspondingly, in another implementation, when the second terminal is a relay terminal, the second terminal uses the Layer 2 identifier of the relay additional discovery information configured in the target configuration information as the destination Layer 2 identifier; and sends the relay discovery additional information through the destination Layer 2 identifier. The first terminal, as a remote terminal, uses the Layer 2 identifier of the relay additional discovery information configured in the target configuration information as the destination Layer 2 identifier; and listens for the relay discovery additional information according to the destination Layer 2 identifier.

[0041] The present invention provides a method for determining a Layer 2 identifier. By using the Layer 2 identifier of the relay additional discovery information configured in the target configuration information, the method determines the destination Layer 2 identifier of the relay additional discovery information. This method can solve the problem that during the process of obtaining additional information from a relay terminal, the relay terminal cannot determine the destination Layer 2 identifier of the relay discovery additional information, which may cause the remote terminal to fail to accurately receive the additional relay information.

[0042] like Figure 4 As shown, one embodiment of the present invention provides a method 400 for determining a Layer 2 identifier. This method can be executed by a terminal device; in other words, it can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0043] S402: When the first terminal is a remote terminal, the Layer 2 identifier of the relay additional discovery information configured in the target configuration information is used as the destination Layer 2 identifier; the relay discovery additional information request is sent through the destination Layer 2 identifier.

[0044] The target information includes the Layer 2 identifier of the relay additional discovery information configured in the target configuration information. Optionally, the target configuration information includes policy parameters, which are configured by the network side or pre-configured in the USIM or ME of the first terminal.

[0045] S404: Receive additional relay discovery information from the second terminal.

[0046] Wherein, the destination Layer 2 identifier of the relay discovery additional information response is the source Layer 2 identifier of the relay discovery additional information request, and the source Layer 2 identifier of the relay discovery additional information response is generated by the second terminal. Therefore, the source Layer 2 identifier of the relay discovery additional information request can be determined as the destination Layer 2 identifier of the relay discovery additional information.

[0047] The present invention provides a method for determining a Layer 2 identifier, which can solve the problem that when a relay terminal cannot determine the destination Layer 2 identifier of the relay to discover additional information during the process of obtaining additional information from the relay terminal, the remote terminal may not be able to accurately receive the additional relay information.

[0048] like Figure 5 As shown, one embodiment of the present invention provides a method 500 for determining a layer 2 identifier. This method can be executed by a terminal device; in other words, it can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0050] The target process includes: relay discovery process, cell identifier broadcast process, or unicast establishment process.

[0051] The remote terminal uses the source layer 2 identifier of the relay terminal obtained during the target process as the destination layer 2 identifier of the relay additional discovery information, and listens for the relay discovery additional information based on the destination layer 2 identifier.

[0052] Correspondingly, in another implementation, when the second terminal is a relay terminal, the second terminal uses the source layer 2 identifier of the remote terminal obtained in the target process as the destination layer 2 identifier of the relay additional discovery information, and sends the relay discovery additional information through the destination layer 2 identifier.

[0053] The first terminal, acting as a remote terminal, uses the source layer 2 identifier of the relay terminal obtained during the target process as the destination layer 2 identifier of the relay additional discovery information, and listens for the relay discovery additional information based on the destination layer 2 identifier.

[0054] The present invention provides a method for determining a Layer 2 identifier, which can solve the problem that when a relay terminal cannot determine the destination Layer 2 identifier of the relay to discover additional information during the process of obtaining additional information from the relay terminal, the remote terminal may not be able to accurately receive the additional relay information.

[0055] like Figure 6 As shown, one embodiment of the present invention provides a method 600 for determining a layer 2 identifier. This method can be executed by a terminal device; in other words, it can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0056] S602: When the first terminal is a remote terminal, the source layer 2 identifier of the relay terminal obtained in the target process is used as the destination layer 2 identifier; a relay discovery additional information request is sent according to the destination layer 2 identifier.

[0057] The target process includes: relay discovery process, cell identifier broadcast process, or unicast establishment process.

[0058] S604: Receive additional relay discovery information from the relay terminal.

[0059] Wherein, the destination layer 2 identifier of the relay discovery additional information response is the source layer 2 identifier of the relay discovery additional information request, and the source layer 2 identifier of the relay discovery additional information response is generated by the relay terminal.

[0060] It should be noted that the method for determining the layer 2 identifier provided in this application embodiment can be executed by a layer 2 identifier determining device, or a control module in that device for executing the loading of the above method.
