38、es a protocol for the exchange of routing and registration information between a Mobile End System (M-ES) and a serving Mobile Data Intermediate System (MD-IS). This part was originally known as Part 407.This protocol is connectionless and is designed to operate in close conjunction with protocols p
39、roviding connectionless mode network service, such as Connectionless Network Protocol (CLNP) ISO-8473 and Internet Protocol (IP) RFC-791. It is also designed to operate in conjunction with the Mobile Network Location Protocol (Part 501) for providing Mobility Management services in the CDPD Network.
40、This protocol provides configuration information about M-ESs to MD-ISs. An MD-IS is informed of the Network Entity Identifiers (NEIs) supported by each M-ES and the subnetwork point of attachment (SNPA) address of the M-ES. That is, a serving MD-IS obtains information that allows it to associate des
41、tination network addresses to specific channel streams and to specific data link connections on the channel stream. Once the MD-IS obtains this information, reachability information and routing metrics concerning these NEIs may be disseminated to other MD-IS for the purpose of calculating routes to/
42、from each M-ES on the subnetwork.This protocol performs logically the same functions specified in ISO-9542. However, the characteristics of the CDPD environment invalidate the operation of ISO-9542 as follows:TIA/EIA-732-507 Mobile Network Registration Protocol507212345678910111213141516171819202122

The Redirection subset of ISO-9542 is invalidated by the Radio Frequency (RF) subnetwork topology, which is a point-to-multipoint star subnetwork type. All data traffic originating from an M-ES is received by, and only by
44、, a single MD-IS controlling the subnetwork channel. There are no better paths to use when forwarding Network Protocol Data Units (NPDUs) to their destination.b. Portions of the Configuration subset of ISO-9542 are invalidated by the RF subnetwork topology and presence of a single MD-IS on the subne
45、twork channel to which the M-ES is attached. Direct M-ES to M-ES communication is not possible, nor can NPDUs be routed other than through the single MD-IS on the subnetwork.c. It is desirable for an M-ES to be able to deregister specific NEIs from the CDPD Network in a controlled manner.2 Overview
46、of the ProtocolThis protocol provides the following services:a. Notification of reachability and registration of NEIs associated with an M-ES to a serving MD-ISb. Conveyance of data origin authentication information about each of an M-ESs NEIsc. Confirmation by an MD-IS of its willingness and abilit
47、y to provide network routing services to an M-ESd. Deregistration of an NEI with the serving MD-IS.NEIs are not valid for use until they have been successfully registered by the procedures defined by this Part. Additional procedures for NEI authentication and access control defined in Part 406 and P
48、art 501 are assisted by information carried in Protocol Data Units (PDUs) defined in this Part. Once confirmation of registration has been received, the M-ES is able to send and receive NPDUs addressed to that NEI and the serving MD-IS is able to validate subsequent use of the NEI by the M-ES on eac
