Introduction As a mobile service network evolves to a versatile packet data network, the service paradigm of mobile operat
24、ors is gradually shifting from voice oriented communication to multimedia information sharing. A mobile device is no longer a simple tool for person to person communication, but now becomes an indispensable item for receiving essential information distributed for human society. Information for enter
25、tainment services such as TV or Radio show, as well as information for public safety, energy saving, environmental conservation, and for searching emergency aid, need to be delivered to the right person at the right time in any location. The multimedia broadcast service, MBMS 2, and packet switched
26、streaming 89 is a widely deployed technique which fulfils the basic service requirements. However provisioning of content is currently allowed for a limited group of content providers, and ordinary users have no way to utilize the service. The rationale of Personal Broadcast Service is to give an op
27、en opportunity for ordinary people to generate content, and broadcast it on air. A variety of broadcast services and a new device market may emerge once users are able to access the content distribution service. Abundant broadcast content will be available to be selected by 3GPP users. The extent of
28、 other potential service area is unbounded. The objective of this document is to present some envisaged use cases of Personal Broadcast Service, for creative engineers and standard developers to pursue further investigation of PBS, and move to the next steps necessary for enhancement of relevant 3GP
29、P standards. ETSI ETSI TR 122 947 V14.0.0 (2017-03)63GPP TR 22.947 version 14.0.0 Release 141 Scope This Technical Report presents potential use cases of Personal Broadcast Service. It aims to take account of service and system aspect of PBS. The minimum set of service requirements associated with e
30、ach use case will be identified. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

39、 Personal Broadcast Service Provider PBSF Personal Broadcast Service Function PBCP Personal Broadcast Contents Provider UGC User Generated Contents VoD Video on Demand 4 General description 4.1 Service concept and definition Personal Broadcast Service (PBS) is a content distribution service using 3G
40、PP accesses. This enables any Internet user, private company or mobile user to generate content, and broadcast/multicast it to mobile users. Types of User Generated Content (UGC) in this context include not only multimedia files such as video, audio or image, but also variety of digital information
41、distributed for various purposes such as e.g. public safety, energy saving, environment conservation. The User Generated Content can be distributed in either a time unconstrained Content on-Demand (CoD) method, or in a time constrained, real-time method. In the former case, the contents are uploaded
42、 to a server and downloaded at the request of users at a convenient time. Most CoD applications and some MBMS user services may be delivered using unicast bearers as defined in 310. However in some application, CoD users may share the content using multicast bearer service. A use case of shared VoD
43、service is presented in this document. In the case of live broadcast, content is delivered to multiple users simultaneously, as such a broadcast or multicast bearer is necessary for resource saving. A broadcast bearer service 3 is efficient when a large number of receivers are expected and the recei
44、vers are spread in many cellular areas. Major TV or Radio services are examples that may utilize such a broadcast bearer. UGC stream may also be transmitted using broadcast bearer if the population of receivers justifies cost for delivering the content. Private show of very popular celebrity or dail
45、y episodes of small production company may be a potential example. Another area of use case is localized broadcast in campus, theatre or theme park. Details of the use cases are presented in this document. In contrast to broadcast bearer service, UGC will be delivered using multicast bearer service
46、in many use cases. Content providers of Personal Broadcast Service may appear and disappear at any time. Content distribution may commence on an ad-hoc basis. Therefore, it will be inefficient to pre-allocate resources for such unpredictable content providers. New interfaces and requirements will be
47、 necessary to support such content providers. The communication may occasionally be bi-directional. Interactive data generated by mobile receivers needs to be passed to content providers. Some additional functions, e.g. time-stamping or adding cell ID, may need to be performed on upstream user data.
48、 This aspects associated with interactivity will be discussed in detail. Currently, 3GPP supports an OMA 6 defined interface to be used between mobile operator and broadcast content provider 4. Therefore, most broadcast applications that require a static allocation of resource may be supported using
49、 existing 3GPP and OMA standards. However new set of requirements and standards may be necessary to support distinctive features of PBS use cases as introduced in this document.
