Embodiment 1

[0093] This embodiment provides a specific embodiment for implementing network sharing and D2D discovery under the D2D technology. In this embodiment, the eNB allocates radio resources used when sending D2D discovery signaling.

[0094] eNB allocates their own discovery resource pools and their own communication resource pools for D2D operators participating in network sharing

[0095] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D communication for each D2D operator in the total resource pool of D2D communication.

[0096] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D discovery for each D2D operator within the total resource pool for D2D discovery.

[0097] The eNB notifies the D2D UEs served by different operators of the D2D discovery resource pool information it uses and the D2D communication resource pool information it uses...

Embodiment 2

[0112] This embodiment provides a specific embodiment for implementing network sharing and D2D discovery under the D2D technology. In this embodiment, the eNB allocates radio resources used when sending D2D discovery signaling. The difference from the first embodiment is that this method is to notify the user equipment in the D2D UE that when sending a resource allocation request, it carries the information of its own service operator.

[0113] The eNB allocates respective discovery resource pools and respective communication resource pools to D2D operators participating in network sharing.

[0114] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D communication for each D2D operator in the total resource pool of D2D communication.

[0115] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D discovery for each D2D operator within the tot...

Embodiment 3

[0129] This embodiment provides a specific embodiment of implementing network sharing and D2D discovery under the D2D technology. In this embodiment, the D2D UE allocates wireless resources used for sending D2D discovery signaling by itself.

[0130] eNB allocates their own discovery resource pools and their own communication resource pools for D2D operators participating in network sharing

[0131] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D communication for each D2D operator in the total resource pool of D2D communication.

[0132] According to the PLMNIDs of the D2D operators participating in network sharing, the eNB allocates a resource pool for D2D discovery for each D2D operator within the total resource pool for D2D discovery.

[0133] The eNB notifies the D2D UEs served by different operators of the D2D discovery resource pool information it uses and the D2D communication resource pool infor...

Abstract

Embodiments of the invention disclose a device-to-device communication method and a system based on network sharing. The method comprises the steps as follows: device-to-device user equipment D2D UE receives at least one piece of following information sent by a network side via a radio or dedicated message, namely, a list of different public land mobile networks supporting D2D, resource pool information of D2D discovery and / or D2D communication of different public land mobile networks PLMN, and a PLMN list corresponding to the resource pool information of the D2D discovery and / or D2D communication; and the D2D UE uses the resource pool information or the resource pool information corresponding to the PLMN list to determine the range of resources used in D2D discovery and / or D2D communication.

Description

technical field [0001] The present invention relates to a device-to-device (D2D, Device-to-Device) communication technology, in particular to a device-to-device communication method and system based on network sharing. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements on the system capacity and coverage of traditional cellular networks. On the other hand, the popularity of applications such as social networks, short-distance data sharing, and local advertisements has gradually increased the demand for proximity services (ProximityService) that people can learn about and communicate with nearby interested people or things. The traditional base station-centric cellular network has obvious limitations in terms of high data rate and proximity service support. Against this background of demand, Device-to-Device (D2D, Device-to- Device) te...
