Terminal Discovery Method, Terminal, Server, Base Station, Management Entity, and System

A terminal discovery method, wherein the method comprises:

• receiving, by a base station, a fourth request sent by a management entity;
• allocating, by the base station, a discovered resource to a second terminal according to the fourth request, wherein the discovered resource is a resource used when the second terminal sends a second message;
• and
• sending, by the base station, the discovered resource to the second terminal, or sending, by the base station, the discovered resource to the management entity such that the management entity sends the discovered resource to the second terminal.

A terminal discovery method, wherein the method comprises:

• receiving, by a management entity, a third request sent by a second terminal, or receiving, by a management entity, a sixth request sent by a server;
• and
• sending, by the management entity, a fourth request to a base station such that the base station allocates and sends a discovered resource to the second terminal according to the fourth request, or sending, by the management entity, a fourth request to a base station, and receiving a discovered resource that is allocated and sent by the base station according to the fourth request, and sending the discovered resource to the second terminal,
• wherein the discovered resource is a resource used when the second terminal sends a second message.

A second terminal, wherein the second terminal comprises:

• a first request sending module configured to send a third request to a management entity such that the management entity sends a fourth request to a base station;
• a second request sending module configured to send a fifth request to a server such that the server sends a sixth request to a management entity, and the management entity sends a fourth request to a base station;
• a first discovered resource receiving module configured to receive a discovered resource sent by the base station, wherein the discovered resource is a resource that is allocated by the base station according to the fourth request;
• and
• a second discovered resource receiving module configured to receive a discovered resource that is sent by the base station to the management entity and sent by the management entity to the second terminal, wherein the discovered resource is the resource that is allocated by the base station according to the fourth request.

A base station, wherein the base station comprises:

• a second request receiving module configured to receive a fourth request sent by a management entity;
• a discovered resource allocating module configured to allocate a discovered resource to a second terminal according to the fourth request received by the second request receiving module, wherein the discovered resource is a resource used when the second terminal sends a second message;
• a first discovered resource sending module configured to send the discovered resource allocated by the discovered resource allocating module, to the second terminal;
• and
• a second discovered resource sending module configured to send the discovered resource allocated by the discovered resource allocating module, to the management entity such that the management entity sends the discovered resource to the second terminal.

A management entity, wherein the management entity comprises:

• a fourth request receiving module configured to receive a third request sent by a second terminal;
• a fifth request receiving module configured to receive a sixth request sent by a server;
• a sixth request sending module configured to send a fourth request to a base station according to the third request or the sixth request such that the base station allocates and sends a discovered resource to the second terminal according to the fourth request;
• a seventh request sending module configured to send the fourth request to the base station according to the third request or the sixth request;
• a third discovered resource receiving module configured to receive a discovered resource that is allocated and sent by the base station according to the fourth request sent by the seventh request sending module;
• and
• a third discovered resource sending module configured to send the discovered resource received by the third discovered resource receiving module to the second terminal, wherein the discovered resource is a resource used when the second terminal sends a second message.
