Abstract

A terminal connection method includes that: a first terminal sends a first message to a second terminal, the first message including a first access layer configuration parameter, and the first access layer configuration parameter being used by the second terminal to configure a parameter of an access layer to communicate with the first terminal.

First claim

The invention claimed is:

1. A method for connecting terminals, comprising:
sending, by a first terminal, a first message to a second terminal, wherein the first message comprises a first access layer configuration parameter, the first access layer configuration parameter being used by the second terminal to configure a parameter of an access layer to communicate with the first terminal,
wherein the method further comprises: before sending, by the first terminal, the first message to the second terminal,
receiving, by the first terminal, a second access layer configuration parameter corresponding to at least one of the first terminal or the second terminal from a first network device, wherein the second access layer configuration parameter comprises a first set of mapping relationships, the first set of mapping relationships comprising a mapping relationship between a Quality of Service (QoS) Flow Identifier (QFI) and a bearer, and the bearer being used for communication between the first terminal and the second terminal.

2. The method of claim 1 , further comprising: before sending, by the first terminal, the first message to the second terminal,
sending, by the first terminal, a first set of QoS attribute information corresponding to at least one of the first terminal or the second terminal to a first network device,
wherein the first set of QoS attribute information includes at least one of:
a PC5 5 th Generation Mobile Communication Technology (5G) QoS Indicator (PQI), a data rate requirement, a communication range requirement, or the QFI.

3. The method of claim 1 , wherein the second access layer configuration parameter is transmitted through Radio Resource Control (RRC) reconfiguration signaling.

4. The method of claim 1 , wherein the first access layer configuration parameter is used by the second terminal to configure a parameter of at least one of following access layers: an SDAP layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, or a physical (PHY) layer.

5. A first terminal, comprising:
a transceiver, configured to send a first message to a second terminal, wherein the first message comprises a first access layer configuration parameter, the first access layer configuration parameter being used by the second terminal to configure a parameter of an access layer to communicate with the first terminal,
wherein the transceiver is further configured to receive a second access layer configuration parameter corresponding to at least one of the first terminal or the second terminal from the first network device before sending the first message to the second terminal, and
wherein the second access layer configuration parameter comprises a mapping relationship between a Quality of Service (QoS) Flow Identifier (QFI) and a bearer, the bearer being used for communication between the first terminal and the second terminal.

6. The first terminal of claim 5 , wherein the transceiver is further configured to send a first set of QoS attribute information corresponding to at least one of the first terminal or the second terminal to a first network device before sending the first message to the second terminal, and the first set of QoS attribute information comprises at least one of the following:
a PC5 5 th Generation Mobile Communication Technology (5G) QoS Indicator (PQI), a data rate requirement, a communication range requirement, or the QFI.

7. The first terminal of claim 5 , wherein the second access layer configuration parameter is transmitted through Radio Resource Control (RRC) reconfiguration signaling.

8. The first terminal of claim 5 , wherein the first access layer configuration parameter is used by the second terminal to configure a parameter of at least one of the following access layers: an SDAP layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, or a physical (PHY) layer.

9. A second terminal, comprising:
a transceiver, configured to receive a first message from a first terminal, wherein the first message comprises a first access layer configuration parameter; and
a processor, which is to configure a parameter of an access layer based on the first access layer configuration parameter to communicate with the first terminal,
wherein the transceiver is configured to send a second set of mapping relationships to the first terminal before receiving the first message from the first terminal, and
wherein the second set of mapping relationships correspond to the second terminal; the second set of mapping relationships comprise a mapping relationship between a Quality of Service (QoS) Flow Identifier (QFI) and a bearer, the bearer being used for communication between the first terminal and the second terminal.

10. The second terminal of claim 9 , wherein the first message comprises at least one of the following information corresponding to at least one of the first terminal or the second terminal:
a PC5 5 th Generation Mobile Communication Technology (5G) QoS Indicator (PQI), a data rate requirement, a communication range requirement, or the QFI.

11. The second terminal of any one of claim 9 , wherein the transceiver is configured to send a second message to the first terminal, the second message comprising a second access layer configuration parameter.

12. The second terminal of claim 11 , wherein the second access layer configuration parameter is transmitted through Radio Resource Control (RRC) reconfiguration signaling.

13. The second terminal of claim 11 , wherein the transceiver sends the second message to the first terminal when at least one of the following conditions is met:
a bearer used by at least one of the first terminal or the second terminal is different from a bearer of the existing connection; or
the bearer used by at least one of the first terminal or the second terminal is the same as the bearer used by the existing connection, but a configured destination terminal is different.
