Embodiment 1

[0076] For the scenario where UE1 is located within the coverage of the operator's network, Picture 10 It is the process of using D2D to realize the public safety communication method according to the preferred embodiment of the present invention Figure one ,Such as Picture 10 As shown, the process includes the following steps:

[0077] Step S1002: UE1 finds UE2 in the neighboring area;

[0078] Among them, the discovery is D2D discovery, that is, direct discovery through the air interface; UE1 automatically uses D2D discovery, or user 1 to which UE1 belongs manually sets UE1 to use D2D discovery;

[0079] Step S1004, UE1 authenticates UE2;

[0080] UE1 queries the subscription data of UE2 through the PSC server and determines whether UE2 has the authority to participate in the PS service. If the authentication fails (for example, the PSC server does not return the subscription data of UE2, or the subscription data shows that UE2 does not subscribe to the PS service), then UE1 does ...

Embodiment 2

[0088] For a scenario where a user uses D2D group communication for public safety communication with two or more UEs at the same time, UE1, UE2, and UE3 subscribe to PS services. Picture 11 It is the process of using D2D to realize the public safety communication method according to the preferred embodiment of the present invention Figure II ,Such as Picture 11 As shown, the process includes the following steps:

[0089] Step S1102, UE1, UE2, UE3 are configured to belong to the same D2D group G1; wherein, the group configuration can be statically or dynamically completed; static configuration can be configured in subscription data, and dynamic configuration can be through attachment / location update / OMA DM, etc. achieve. It should be noted that the D2D group refers to that the communication between UEs in the group can be realized through D2D group communication, and the members of the D2D group have the same group identifier, such as G1.

[0090] In step S1104, group members UE1...

Embodiment 3

[0096] For the scenario where a PS UE acts as a relay for PS communication, Picture 12 It is the process of using D2D to realize the public safety communication method according to the preferred embodiment of the present invention Figure three ,Such as Picture 12 As shown, user equipment UE1 and UE2 are within the D2D communication range, UE2 and UE3 are within the D2D communication range, and UE1 and UE3 are not within the D2D communication range. UE2 has the capability of relay communication; UE1, UE2, and UE3 are configured into group G1. The procedure includes the following steps:

[0097] In step S1202, UE1, UE2, and UE3 exchange the UE lists in their neighboring areas. This step is the same as step S1104, and will not be repeated here.

[0098] In step S1204, UE1 notifies the start of G1 group communication. This step is the same as step S1106, and will not be repeated here.

[0099] Step S1206: UE2 forwards the G1 group notification message to UE3. Among them, UE2 judges t...

Abstract

Provided are a method and system for processing a public safety communication. The method comprises: a source D2D device sending a public safety communication request to a target D2D device over a public safety spectrum; the source D2D device and the target D2D device performing mutual authentication/authorization over the public safety spectrum; and in the case where mutual authentication/authorization has been passed, the source D2D device and the target D2D device performing public safety communication over the public safety spectrum. By means of the present invention, the problems of non-uniform technologies for realizing public safety networks, poor interoperability, and high network loads which exist in the related art are solved, thereby achieving an effect that using D2D to realize public safety communication can not only reduce the network load, but can also improve the robustness of public safety communication.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and system for processing public safety communications. Background technique [0002] Two types of networks provide wide-area wireless communication: commercial cellular networks and private public safety networks. The public safety network provides communications for public services such as public security, fire protection, and first aid. Public safety networks require high robustness and address specific communication requirements for emergency service communications. The representative system is the Terrestrial Trunked Radio (TETRA) system defined by the European Telecommunications Standards Institute (ETSI). It can provide a series of functions that were not previously used in commercial cellular systems. stand by. Emergency communication is also a type of public safety communication. [0003] Mobile broadband enables people to communicate in more ways anywhere, en...
