The technical scheme of the invention is used for realizing direct communication between the near-distance user equipment, namely Proximity Services (ProSe for short).

Fig. 1 is a flowchart of a first embodiment of a communication method provided by the present invention, and as shown in fig. 1, the communication method of the present embodiment includes:

s101, a first network entity receives a first message sent by first User Equipment (UE), or the first network entity receives a second message sent by a first proximity service server.

Optionally, the first message or the second message may include at least one of:

identification information of the second UE;

the first UE and the second UE are proximate to an identity of the traffic direct communication path.

For example, the identification information of the second UE may be directly carried in the first message, or the identification information of the second UE may be indicated by the identifications of the first UE and the second UE in the proximity service direct communication path in the first message.

The identification information of the second UE may be an ID of the second UE, a ProSe ID, or identification information such as an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), a Global Unique Temporary Identity (GUTI), and the like, which is not limited in this embodiment.

It is understood that the first message may also include identification information of the first UE, and the identification information of the first UE may be a ProSe ID or identification information such as IMSI, IMEI, GUTI, and the like.

S102, a first network entity initiates a first proximity service process to a first UE, so that the first UE obtains a first resource allocated by a first base station to the first UE and a second resource allocated by a second base station to a second UE.

Specifically, the network entity receives a first message sent by a first UE, or after receiving a second message sent by a first proximity service server, the network entity initiates a first proximity service process for the first UE, so that the first UE obtains a first resource allocated by a first base station to the first UE and a second resource allocated by a second base station to the second UE, where the first proximity service process may include all interactive operations performed by the first network entity, which are performed by the first UE, to enable the first UE to obtain the first resource and the second resource.

S103, the first network entity triggers the second network entity to initiate second proximity service processing on the second UE, so that the second UE can acquire the first resource and the second resource.

The second proximity traffic process may be all interoperations performed by the second network entity to cause the second UE to acquire the first resource and the second resource.

Specifically, when a first UE needs to implement direct communication with a second UE, it needs to acquire communication resources required for communication, that is, a first resource allocated by a first base station to the first UE, a second resource allocated by a second base station to the second UE, and an IP address of the second UE, and it can be understood that the second UE also needs to acquire communication resources required for communication, that is, the first resource, the second resource, and the IP address of the first UE, based on which, the first UE and the second UE can use the IP addresses of the first UE and the second UE as a source address and a destination address of an IP data packet therebetween, and simultaneously the first UE uses the first resource to perform data transmission and uses the second resource to perform data reception; the second UE uses the second resource to transmit data and uses the first resource to receive data; meanwhile, the measurement report can be sent to the base station according to the measurement control, and the base station can also be sent to the network entity.

In this embodiment, a first network entity initiates a first proximity service process for a first UE, which may only enable the first UE to acquire a first resource and a second resource, and a second network entity is triggered by the first network entity to initiate a second proximity service process for a second UE, which may only enable the second UE to acquire the first resource and the second resource, and then the first UE and the second UE use the first resource and the second resource to acquire an IP address of the other party through signaling interaction of a control plane, that is, the first UE acquires an IP address of the second UE, so that the second UE acquires the IP address of the first UE.

Another possible implementation manner is that the first network entity initiates a first proximity service process for the first UE, so that the first UE can acquire the first resource, the second resource, and the IP address of the second UE, and the first network entity triggers the second network entity to initiate a second proximity service process for the second UE, so that the second UE can acquire the first resource, the second resource, and the IP address of the first UE.

The bearer establishment request message at least comprises first UE identification information, second UE identification information and a direct connection ID allocated by the MME, and can indicate the first base station to allocate resources for the prose service. The bearer establishment request message is a possible implementation of the twelfth message in the present invention, and the message for implementing the function may also be a proximity communication Resource allocation request (ProSe Comm Resource allocation request) including the first UE, the second UE identity, and the direct connection ID

S1204, the first base station sends a bearer establishment response message to the first network entity.
