The present invention relates to the provision of a middleware platform apparatus and related method operating on top of the heterogeneous wireless network. In other words, there is provided at least one bearer service in a heterogeneous wireless network for at least one application running at a mobile endpoint roaming in the heterogeneous wireless network. It is proposed to dynamically adjust (S, S) the at least one bearer service provided through the heterogeneous wireless network () according to an operational context of a mobile endpoint ().

Middleware platform

A switching station etc., are provided. When a mobile station moves from an area of a switching station into an area of another switching station having a VLR which has accepted the maximum number of subscribers, the switching station registers subscriber location information about the mobile station in an HLR even through it cannot register the subscriber service information in its VLR. When a call origination signal is transmitted from the mobile station, the switching station performs call origination connection processing by acquiring the subscriber service information about the mobile station from the HLR. When call termination to the mobile station occurs, the switching station can perform call termination processing normally since the subscriber location information is correctly updated in the HLR. The switching station performs call termination processing by acquiring the subscriber service information from the HLR.
