1、 ATIS-0700008 ATIS Standard on - CELL BROADCAST ENTITY (CBE) TO CELL BROADCAST CENTER (CBC) INTERFACE SPECIFICATION ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment a

2、nd communications industry. More than 250 companies actively formulate standards in ATIS 18 Committees, covering issues including: IPTV, Service Oriented Networks, Energy Efficiency, IP-Based and Wireless Technologies, Quality of Service, and Billing and Operational Support. In addition, numerous In

3、cubators, Focus and Exploratory Groups address emerging industry priorities including “Green”, IP Downloadable Security, Next Generation Carrier Interconnect, IPv6 and Convergence. ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a member and major

4、 U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications Sectors, and a member of the Inter-American Telecommunication Commission (CITEL). For more information, please visit . Notice of Disclaimer to identify the requirements on the CBE and CBC to support the

5、 interface; and to identify requirements to support assumptions made in other specifications, such as the 3GPP specifications (e.g., Ref 1). One of the main goals behind CBE to CBC interface is to have a common interface from CBE to CBC that is independent of Cell Broadcast applications and the tech

6、nologies associated with the CMSP infrastructure. Any application-dependent functions are to be handled by the CBE, whereas any technology-dependent functions (e.g., GSM, UMTS, LTE) are to be handled by the CBC. 1.3 Application This specification is applicable to a CBE interfacing to a CBC. This spe

7、cification is independent of the application supported by the Cell Broadcast Service, and is intended to support any text-based application over the Cell Broadcast Service. 2 NORMATIVE REFERENCES The following standards contain provisions which, through reference in this text, constitute provisions

8、of this ATIS Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this ATIS Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
