Embodiment 1

[0113] This embodiment provides a method for establishing D2D multicast broadcast communication in a no-coverage scenario. The feature of this embodiment is that there is no central node for resource coordination and allocation of D2D multicast / broadcast air interface identifiers, and the UE needs to independently complete resource competition and D2D multicast / broadcast air interface identifier mapping or acquisition in a predefined manner. The following is described in detail by Examples 1 to 5.

example 1

[0115] In the public security scenario, Officers A, B, C, and D use public security UE1, UE2, UE3, and UE4 with D2D functions. Officers A, B, C, and D all subscribe to public security services, and UE1, UE2, and UE3 are configured to belong to D2D communication group X, while UE4 belongs to D2D communication group Y. Before Officers A, B, C, and D arrive at the rescue location, the D2D communication group identifier GID and wireless resource information for public safety are known in advance, where the wireless resource information may include frequency point and frequency band information. After arriving at the rescue location, none of them are within the coverage of the network, but UE1, UE2, UE3, and UE4 are within the D2D communication range of each other.

[0116] At the rescue site, Officer A wants to initiate a multicast communication to inform other Officers in the group of related information. UE1 of Officer A monitors the usage of pre-allocated wireless resources, a...

example 2

[0119] In the public security scenario, Officers A, B, C, and D use public security UE1, UE2, UE3, and UE4 with D2D functions. Officers A, B, C, and D all subscribe to public security services, and UE1, UE2, and UE3 are configured to belong to D2D communication group X, while UE4 belongs to D2D communication group Y. Before Officers A, B, C, and D arrive at the rescue location, they should know the GID of the D2D communication group application layer and the wireless resource information for public safety in advance, where the wireless resource information can include frequency point and frequency band information. After arriving at the rescue location, none of the UEs is within the coverage of the network, but UE1, UE2, UE3, and UE4 are within the D2D communication range of each other.

[0120] At the rescue site, Officer A wants to initiate a multicast communication to inform other Officers in the group of related information. At the same time, UE2, UE3, and UE4 of Officer ...

Abstract

The present invention provides a device-to-device D2D multicast / broadcast communication processing method, device, and user equipment. The method includes: acquiring an air interface identifier for identifying D2D multicast / broadcast communication and / or D2D multicast / broadcast communication Resource information: perform D2D multicast / broadcast communication processing on resources corresponding to the resource information according to the air interface identifier. The present invention solves the problem in the related art that the UE cannot implement D2D multicast and broadcast communication in the scenarios of no coverage or coverage and partial coverage, and further achieves the goal of making the UE in the scenarios of no coverage or coverage and partial coverage The effect of smooth D2D multicast and broadcast communication.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device-to-device D2D multicast / broadcast communication processing method, device and user equipment. 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, application scenarios such as public security, social networking, short-distance data sharing, and local advertising have gradually increased people's demand for understanding and communicating with nearby people or things (Proximity Services, Proximity Services). 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 (Device-to-Device, Referred to as D2D) technology c...
