Negotiation requirements for the extended mobile service environment

The Japanese mobile phone markets proved in the late 1990's by selling a great number of attachable intelligent devices with i-mode phone that mobile devices have a market driven need to serve as a gateway to the Internet for devices that are lacking a radio module such as PDA equipment and lap top computers. They are referred to as terminal equipment and when attached to a mobile phone's service environment they impose additional requirements for a mobile phone’s capability negotiation framework. They increase a user's service personalisation options and cause additional threats to service security. All these new requirements must be negotiated in the service environment. This paper aims to define some of the additional negotiation requirements imposed by terminal equipment (TE) for a mobile service environment. The research method in the paper is based on the constructive method of related publications and technologies and the results are derived from the abstractive analysis of the available material. The over all discoveries were that terminal equipment must have a capability register, three new capability attributes are needed, the Session Initiation Protocol (SIP) should be utilised for profile capability negotiation and the capability negotiation event should me managed by mobile terminal (MT) for the TE-MT functional split
