in response to sending the attach request message, receive information about the resource for broadcasting the information of the UE; and
broadcast the information of the UE on the resource for establishing the D2D connection with another UE, wherein the information of the UE comprises an identifier of the UE and a service code of the UE, and the service code of the UE indicates application layer service information.
5. The UE of claim 4 , wherein a protocol stack of an air interface between the UE and the another UE comprises a user plane protocol stack, wherein the user plane protocol stack comprises at least one of internet protocol, media access control-d (MAC-d) information, and physical layer information.
6. The UE of claim 4 , wherein the resource for establishing the D2D connection comprises an acquired resource in a discontinuous transmission (DTX) cycle.
7. An apparatus configured in a user equipment (UE), comprising:
a storage medium storing executable instructions; and
a processor, wherein the executable instructions, when executed by the processor, cause the UE to:
send an attach request message to a base station for triggering the base station to allocate a resource for broadcasting information of the UE, wherein the attach request message triggers the base station to send an initial UE message that includes the attach request message in a non-access-stratum protocol data unit (NAS-PDU) information element of the initial UE message to a mobility management entity, the attach request message comprises a device-to-device (D2D) capability of the UE and an indication for a bearer for a D2D connection, the first message indicates the mobility management entity to send an initial context setup request message that includes an attach accept message in a NAS-PDU information element of the initial context setup request message to the base station, and the initial context setup request message indicates that a D2D function is supported in a UE radio capability information element of the initial context setup request message;
in response to sending the attach request message, receive information about the resource for broadcasting the information of the UE; and
broadcast the information of the UE on the resource for establishing the D2D connection with another UE, wherein the information of the UE comprises an identifier of the UE and a service code of the UE, wherein the resource is allocated by the base station, and the service code of the UE indicates application layer service information.
8. The apparatus of claim 7 , wherein a protocol stack of an air interface between the UE and the another UE comprises a user plane protocol stack, wherein the user plane protocol stack comprises at least one of internet protocol, media access control-d (MAC-d) information, and physical layer information.
9. The apparatus of claim 7 , wherein the resource for establishing the D2D connection comprises an acquired resource in a discontinuous transmission (DTX) cycle.
10. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause a user equipment (UE) to carry out steps of:
