TRANSFERENCIA ENTRE REDES INALAMBRICAS DE DIFERENTES TECNOLOGIAS.

摘要

A telecommunications apparatus comprises an applications server and a mobility manager. The applications server is operable to provide a telecommunications service to at least one mobile terminal via at least one of a first access network and a second access network. The mobility manager is operable to monitor an affiliation of the mobile terminal with at least the first and the second access networks. The applications server in combination with the mobility manager is operable to negotiate a change in the telecommunications service as a result of the change in communications parameters associated with the change of affiliation from the first to the second access networks. The telecommunications apparatus can provide a facility for a mobile terminal to change affiliation, from one access network to another access network, with the effect that the mobile terminal is provided with one of a pre-specified set of services which can be supported by the second access network. Accordingly, when there is a change of communications parameters, resulting from the mobile terminal changing affiliation, a facility for changing the service to the mobile terminal is provided in accordance with the change of communications parameters, reducing a likelihood of services crashing.
