Abstract
Provided in the embodiment of the present invention are a D2D-based communication method and a terminal. The method comprises: a first terminal receives a discovery signal of a second terminal, the discovery signal comprising indication information for indicating the capability and/or the status of the second terminal; and the first terminal performs D2D communication with the second terminal on the basis of the instruction information. The embodiment of the present invention implements the D2D communication on the basis of the capability and/or status of the terminal, improving the flexibility of the D2D communication mode.
Claims13
A Device to Device (D2D)-based communication method, comprising:
- receiving, by a first terminal, a discovery signal of a second terminal, wherein the discovery signal comprises indication information,
- wherein the indication information comprises at least one of:
- information indicating whether the second terminal allows another terminal to access a base station through the second terminal, information indicating a type of a service for which the second terminal allows other terminals to access the base station through the second terminal or information indicating an access probability of a service;
- determining, by the first terminal, a state of the second terminal according to the indication information;
- determining, by the first terminal, whether the first terminal is allowed to access the base station through the second terminal according to the state of the second terminal;
- and
- when the first terminal determines that the first terminal is allowed to access the base station through the second terminal, performing, by the first terminal, D2D communication with the second terminal to access the base station.
A terminal, which is a first D2D-based communication terminal, the first terminal comprising a processor and one or more units stored on a memory and executable by the processor, the one or more units comprises:
- a receiving unit, configured to receive a discovery signal of a second terminal, wherein the discovery signal comprises indication information, wherein the indication information comprises at least one of:
- information indicating whether the second terminal allows another terminal to access a base station through the second terminal, information indicating a type of a service for which the second terminal allows other terminals to access the base station through the second terminal or information indicating an access probability of a service;
- and
- a communication unit, configured to perform D2D communication with the second terminal according to the indication information;
- wherein the communication unit is configured to determine a state of the second terminal according to the indication information, determine whether the first terminal is allowed to access the base station through the second terminal according to the state of the second terminal, and when the communication unit determines that the first terminal is allowed to access the base station through the second terminal, perform, by the communication unit with the second terminal to access the base station.
