33、Foreword TIAIEIAITSB-87-2016 PART 2016 Multicast Perspectives O Foreword This foreword is not part of this Telecommunications Systems Bulletin. This Telecommunications Systems Bulletin has been developed by Subcommittee TR-45.6, and contains information which may be useful to implementors of systems
34、 compliant with TSB-87, “Cellular Digital Packet Data System Specification,“ or its derivatives. This document contains significant portions of material originally submitted by the Cellular Digital Packet Data Forum Inc. CDPD is a technology intended to provide packet data networking services to mob
35、ile hosts. The media used to provide these services consists of radio channels typically used for Advanced Mobile Phone System (AMPS) cellular service. 0.1 Docu ment Structure This Telecommunications Systems Bulletin is published as a series of Parts. Each Part contains information pertaining to one
36、 aspect of the system. The functional structure of this TSB is as follows: o Part 1000 to Part 1999-Guidelines for Service Providers These Parts are informative and discuss non-CDPD specific entities (such as Intermediate Systems), support services (such as directory - 2016-iii Previous page is blan
37、k TIA/EISB-87-2016 Multicast Persrrectives services, accounting summary and settlement procedures, authentication, etc.), value-added services (such as subscriber location) and Service Provider issues (such as an interoperability test plan overview and parameter configuration). Part 1000 contains th
38、e detailed listing of all Parts of this TSB. Part 2000 to Part 2999-Guidelines for Manufacturers of CDPD equipment These Parts are informative and discuss such concerns as CDPD-specific entities (such as Mobile End Systems (M-ESs), Mobile Data Base Stations (MDBSs) and Mobile Data Intermediate Syste
39、ms (MD-ISS), external interfaces (such as that between the Subscriber Unit (SU) and the Subscriber Identity Module (SIM) and multicasts from the perspective of each of the participating entities. Part 3000 to Part 3999-Guidelines for the CDPD Network Information Center (NIC). These Parts are informa
40、tive and describe the issues and procedures which must be addressed by an agency serving as a NIC on behalf of the CDPD community. o o 20161v Introduction TINEIAKSB-87-2016 PART 2016 Multicast Perspectives 1 Introduction The Multicast Perspectives is a high level view of the processes involved in re
41、ndering CDPD and IP Multicast services. The CDPD Multicast service features include the following: a. b. C. d. e. f. Multiple M-ESs get a copy of the message, regardless of the number of M-ESs or their location More efficient use of the network; therefore, it should be less work for applications Una
42、cknowledged; no confirmation of reception by intended receivers Data is not encrypted by the network Multicast registrations are authenticated on a per-Multicast group member basis; each Multicast group member has its own authentication credentials for a Multicast NE1 Application must use UDP-style
43、transport service: TCP-style transport service is not valid for Multicast. 1.1 CDPD M u It icast Ad min ist rat ion Service The administration of a Multicast Group Member Identifier (GMID) for each of the members of a Multicast NEI, is performed by the Service Provider - 201 6-1 TIAIEIAITSB-87-2016
44、Multicast Perspectives who operates the MD-IS that is the home of a Multicast NEI. The administration of a Multicast NE1 between Service Providers occurs over the I-interface using the Remote Activation interexchange as described in Part 1017. 1.2 CDPD Multicast Data Reliability Since the data is se
45、nt through any IP network using UDP unacknowledged link service, one possible suggestion is to let the application level provide any required increase in reliability protection. Other data systems with similar multicast function get around this problem by transmitting the packet more than once and l
46、etting duplicate detection, based on sequence numbers, ensure only one copy is passed to the application. 1.3 M-ES CDPD Multicast View 1.3.1 Multicast Registration Before registering a Multicast NEI, the M-ES must acquire a point-to-point TE1 and have entered the Mobile Data Link Protocol establishe
47、d state and established point-to-point encryption with the serving MD-IS to allow for authentication over an encr.ypted Airlink. a. Registering a Multicast NE1 requires the M-ES to: Transmit an END SYSTEM HELLO (ESH) Packet Data Unit (PDU) containing the NEI, the Multicast Group Member Identifier (G
48、MID) and its appropriate authentication credentials. The ESH PDU is transmitted using the MDLP acknowledged data service (i.e., within an I frame). NE1 registrations are completely independent of each other-there is no need (for example) to register a point-to-point NE1 prior to a Multicast NEI. b.
49、All normal Mobile Network Registration Protocol (MNRP) actions are followed after this point, i.e., expecting an INTERMEDIATE SYSTEM CONFIRM (ISC), retransmitting on Response Timer or Configuration timer expiration or responding to END SYSTEM QUERY (ESQ) Changing the Authentication Credentials is optional, if an ISC was recently performed. The Multicast IP PDU segments are received as SN-UNITDATA PDUs via the MDLP unacknowledged data service using TEI= 1. Segments are reassembled into a complete IP packet using the procedure specified in IS-732-4041. d. On a cell transfer, an
