Embodiment 1

[0076] For the scenario where UE1 is located within the coverage of the operator's network, Figure 10 It is a process of implementing a public safety communication method using D2D according to a preferred embodiment of the present invention Figure 1 ,Such as Figure 10 As shown, the process includes the following steps:

[0077] Step S1002, UE1 discovers UE2 in the adjacent 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 judges whether UE2 has the right to participate in the PS service. UE2 initiates a PS service request.

[0081] The PSC server may store the subscription data locally or query the subscription data of the UE2 through a home subscriber server (Home Subscriber Serve...

Embodiment 2

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

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

Embodiment 3

[0096] For the scenario where a PS UE acts as a relay for PS communication, Figure 12 It is a process of implementing a public safety communication method using D2D according to a preferred embodiment of the present invention Figure three ,Such as Figure 12 As shown, 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 relay communication capability; UE1, UE2, and UE3 are configured in group G1, and the process includes the following steps:

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

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

[0099] Step S1206, UE2 forwards the G1 group notification message to UE3. Wherein, UE2 judges that UE3 belongs to group G1 throu...

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 communication field, and in particular, to a public safety communication processing method and system. Background technique [0002] Two types of networks provide wide-area wireless communications: commercial cellular networks and private public safety networks. Public safety networks provide communications for public services such as police, fire, and first aid. Public safety networks require high robustness and address the specific communication needs of emergency services communications. The representative system is the Terrestrial Trunked Radio (TETRA) system defined by the European Telecommunications Standards Institute (ETSI), which can provide a series of functions that were not previously supported in commercial cellular systems . Emergency communication is also a kind of public safety communication. [0003] Mobile broadband enables more ways for people to communicate anywhere, enabling governments and ...
