1、 ATIS-0700008.v002 ATIS Standard on - Cell Broadcast Entity (CBE)-to-Cell Broadcast Center (CBC) Interface Specification As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings together the top global ICT companies to advan
2、ce the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, 5G, network functions virtualization, big data analytics, cloud services, device solutions, emergency services, M2M, cyber security, network evolution, quality
3、 of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions, and interoperability testing. ATIS is accredit
4、ed by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of the International Telecommunication Union (ITU), as well as a membe
5、r of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. Notice of Disclaimer to identify the requirements on the CBE and CBC to support the interface; and to identify requirements to support assumptions made in other specifications, such as the 3GPP sp
6、ecifications (e.g., Ref 1). One of the main goals behind the CBE-to-CBC interface is to have a common interface from the CBE to the CBC that is independent of Cell Broadcast applications and the technologies associated with the Commercial Mobile Service Provider (CMSP) infrastructure. Any applicatio
7、n-dependent functions are to be handled by the CBE, whereas any technology-dependent functions e.g., Global System for Mobile communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE) are to be handled by the CBC. 1.3 Application This specification is applica
8、ble to a CBE interfacing to a CBC. This specification is independent of the application supported by the Cell Broadcast Service (CBS) and is intended to support any text-based application over the Cell Broadcast Service. Depending on operator policy, a CBC may have to support the CBE-to-CBC interfac
9、e protocol as defined in this specification and the previous version of the CBE-to CBC-interface protocol as specified in ATIS-0700008 Ref 8. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this ATIS Standard.
