A method and apparatus for negotiating mobile services

摘要

A method and apparatus for performing a service negotiation between a mobile terminal (100) and a server (110) offering mobile services. A service request is received from the mobile terminal (100) including a list of requested services, which is compared with a set of available services that the server (110) can provide. It is then determined which services that were requested but are not available and cannot be provided by the server (110). A delta list is finally transmitted to the mobile terminal (100) comprising the services not available, such that the mobile terminal (100) can determine which services that can be used. A pre-defined tree structure is preferably used for specifying services in the service request and delta lists such that a single root node specifies all services in nodes subordinated to the root node. In this way, the amount of exchanged information and processing in the mobile terminal are reduced.
