Method for establishing connected state, terminal, core network function, and access network device
This application discloses a method for establishing a connected state, a terminal, a core network function, and an access network device. A method for establishing a connected state performed by a first terminal includes: receiving first information sent by a second terminal, where the first information includes at least one of: a second identifier, and network access information; and sending first indication information to a network side, where the first indication information includes at least one of: the second identifier, and a first identifier. The second identifier is used for indicating, to the network side, that the second terminal enters a connected state, and the first identifier is used for indicating, to the network side, that the first terminal enters a connected state.
1 . A method for establishing a connected state, performed by a first terminal, the method comprising:
receiving first information sent by a second terminal, wherein the first information comprises a second identifier, or the first information comprises the second identifier and network access information; and
sending first indication information to a first core network function, wherein the first indication information comprises the second identifier, and a first identifier, wherein
the second identifier is used for indicating, to the first core network function, that the second terminal enters a connected state, and the first identifier is used for indicating, to the first core network function, that the first terminal enters a connected state.
2 . The method according to claim 1 , wherein the first terminal sends, through the second terminal, the first indication information to the first core network function.
3 . The method according to claim 1 , wherein the network access information is obtained by the second terminal from a random access process.
4 . The method according to claim 1 , wherein the network access information comprises at least one of: synchronization information of an access network device; beam information of the access network device; contention resolution identifier; and radio resource control RRC configuration information.
5 . The method according to claim 1 , wherein the first terminal receives the first information sent by the second terminal in a PC 5 connection establishment process of the first terminal and the second terminal.
6 . The method according to claim 1 , further comprising:
sending, through the second terminal, a Msg3 to a network side; and
receiving, through the second terminal, a Msg4 from the network side.
7 . The method according to claim 1 , further comprising:
receiving a Msg3 sent by the second terminal and forwarding the Msg3 to the to a network side; and
receiving a Msg4 from the network side and sending the Msg4 to the second terminal.
8 . A first terminal, comprising a processor, a memory, and a program or an instruction stored in the memory and executable in the processor, wherein the program or instruction is executed by the processor to perform:
receiving first information sent by a second terminal, wherein the first information comprises a second identifier, or the first information comprises the second identifier and network access information; and
sending first indication information to a first core network function, wherein the first indication information comprises the second identifier, and a first identifier, wherein
the second identifier is used for indicating, to the first core network function, that the second terminal enters a connected state, and the first identifier is used for indicating, to the first core network function, that the first terminal enters a connected state.
9 . The first terminal according to claim 8 , wherein the first terminal sends, through the second terminal, the first indication information to the first core network function.
10 . The first terminal according to claim 8 , wherein the network access information is obtained by the second terminal from a random access process.
11 . The first terminal according to claim 8 , wherein the network access information comprises at least one of: synchronization information of an access network device; beam information of the access network device; contention resolution identifier; and radio resource control RRC configuration information.
12 . The first terminal according to claim 8 , wherein the first terminal receives the first information sent by the second terminal in a PC5 connection establishment process of the first terminal and the second terminal.
13 . The first terminal according to claim 8 , wherein the program or instruction is executed by the processor to perform:
sending, through the second terminal, a Msg3 to a network side; and
receiving, through the second terminal, a Msg4 from the network side.
14 . The first terminal according to claim 8 , wherein the program or instruction is executed by the processor to perform:
receiving a Msg3 sent by the second terminal and forwarding the Msg3 to the to a network side; and
receiving a Msg4 from the network side and sending the Msg4 to the second terminal.
