Embodiment 1

[0053] Figure 4 Shown is the processing flow of resource allocation and D2D device discovery provided in Embodiment 1 of the present invention. For the convenience of description, the user terminal as the sender in the D2D device is called the first user terminal, and the user terminal as the receiver is called It is called the second user terminal, and specifically includes the following processing steps:

[0054] Step 401 , when the transmission period arrives, the base station determines the first communication resource for discovering D2D devices allocated to the user terminal in advance according to the resource requirements of the D2D service and corresponding to the current environment.

[0055] The first communication resource is that the base station pre-allocates communication resources corresponding to the environmental conditions for the user terminal based on its own different environmental conditions and according to the resource requirements of the D2D service....

Embodiment 2

[0070] Figure 5 Shown is the processing flow of resource allocation and D2D device discovery provided in Embodiment 2 of the present invention. For the convenience of description, the user terminal as the sender in the D2D device is called the first user terminal, and the user terminal as the receiver is called It is called the second user terminal, and specifically includes the following processing steps:

[0071] Step 501 , the first user terminal having the requirement of initiating a D2D service sends a D2D resource allocation request to the base station, for requesting resources for discovering D2D devices from the base station.

[0072] Further, the sent D2D resource allocation request may also carry service attribute information of the application service carried by the D2D service initiated by the first user terminal, such as service type and service ID.

[0073] Step 502: After receiving the D2D resource allocation request sent by the first user terminal, the base s...

Embodiment 3

[0100] Based on the same inventive concept, according to the method for sending a resource allocation message provided in the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a base station, the structural diagram of which is as follows Image 6 shown, including:

[0101] The allocating unit 601 is configured to allocate a first communication resource for discovering a D2D device to a user terminal according to a preset allocation policy and according to the resource requirement of the current device-to-device communication D2D service;

[0102] The first sending unit 602 is configured to send a D2D resource allocation message carrying the allocated first communication resource.

[0103] Further, the allocating unit 601 is specifically configured to, when the sending period arrives, determine the first communication resources for discovering D2D devices allocated to the user terminal in advance according...

Abstract

Disclosed are a resource allocation message sending method, a device discovery method, and a related device, comprising: a base station allocating, according to a preset allocation policy and according to a resource demand of a current D2D service, a first communication resource used for discovering a D2D device to a user terminal; and sending a D2D resource allocation message carrying the allocated first communication resource. Correspondingly, the user terminal serving as a sender in the D2D device and the user terminal serving as a receiver in the D2D device may use the first communication resource allocated by the base station to discover the D2D device. By means of the solutions provided by embodiments of the present invention, the waste of the communication resources used for discovering the D2D device is reduced.

Description

technical field [0001] The present invention relates to the technical field of D2D (Device to Device Communication, device-to-device communication) in the technical field of wireless communication, and in particular to a resource allocation message sending method, a device discovery method and related devices. Background technique [0002] The D2D technology refers to a technology that directly communicates between user terminals without infrastructure. Traditional D2D technologies include bluetooth, wifi direct, etc. At present, in the actual application of the current cellular network, the user terminals do not have the D2D function, and the communication between the user terminals must be performed by the base station for data forwarding. The introduction of D2D technology in the cellular network can enable user terminals with close distances to discover each other and directly perform data transmission, which can save air interface and core network resources, and provid...
