연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A group transfer function (GTF) receives a plurality of inputs and media for delivery to a plurality of mobile devices. The mobile devices are served by a plurality of cells potentially having a plurality of different radio access technologies such that each mobile device is wirelessly connected to one of the cells. The GTF applies policy rules to the inputs to determine, for each mobile device, content delivery using point-to-multipoint or point-to-point media transport based on the capabilities of the servicing cell. The GTF initiates an allocation of a set of resources in each cell to transport the media to each mobile device in the group using the determined media transport for that mobile device. Media is then replicated by the GTF for delivery to the mobile devices over the allocated resources.

1. A method of delivering media to a plurality of mobile devices in a communication group, the method comprising: a group transport function (GTF) performing:receiving media for delivery to a plurality of mobile devices in a group, wherein the plurality of mobile devices are served by a plurality of cells, wherein each mobile device is wirelessly connected to one of the cells;receiving a plurality of inputs comprising at least capabilities of each mobile device in the group to receive the media using point-to-multipoint media transport and capabilities of each cell of the plurality of cells to deliver the media using point-to-multipoint or point-to-point transport;applying a set of policy rules to the plurality of inputs to determine, for each mobile device in the group, whether to deliver the content to the mobile device using point-to-multipoint or point-to-point media transport, wherein the policy rules are based on one or more of a role, in the communication group, of a group member associated with the mobile device and a type of an incident for which a group member associated with the mobile device is involved;initiating an allocation of a set of resources in each cell to transport the media to each mobile device in the group using the determined media transport for that mobile device, wherein initiating an allocation of a set of resources comprises initiating allocation of at least one Multicast Broadcast Multimedia Service bearer;replicating the media; andconveying the replicated media to the plurality of cells for delivery to the plurality of mobile devices over the allocated resources using the determined media transport for each mobile device. 2. The method of claim 1, wherein initiating an allocation of a set of resources in each cell further includes updating the plurality of inputs. 3. The method of claim 2, wherein the inputs are provided by each cell to the GTF. 4. The method of claim 1, wherein initiating an allocation of a set of resources in each cell further includes updating allocation of a set of resources in each cell subject to at least one real time constraint. 5. The method of claim 1, wherein initiating an allocation of a set of resources in each cell further includes re-determining utilization of point-to-point or point-to-multipoint resources based on updated inputs received by the GTF. 6. The method of claim 1, wherein the plurality of mobile devices are served by a plurality of cells operating using at least two different radio technologies. 7. The method of claim 1, wherein initiating an allocation of a set of resources comprises initiating a point-to-multipoint resource or a point-to-point resource. 8. The method of claim 1, wherein the group is a first responder group. 9. The method of claim 1, wherein initiating an allocation of a at least one Multicast Broadcast Multimedia Service bearer comprises initiating at least one resource for an LTE evolved Multicast Broadcast Multimedia Services (eMBMS) communication group. 10. The method of claim 1, wherein initiating an allocation of a set of resources comprises initiating at least one resource for a Land Mobile Radio (LMR)-based communication group. 11. The method of claim 1, wherein the plurality of inputs further comprises proximal location of the plurality of mobile devices from a zone of interest to at least one cell in the plurality of cells. 12.
