An arrangement and method for radio network relocation of a mobile terminal () from a first base station controller () to a second base station controller (') by anchoring at least some SGSN functions with respect to the first base station controller; and relocating at least some RNC functions from the first base station controller to the second base station controller. RNC (), SGSN () and GGSN () components may be integrated together, and the RNC () may be parented by an SGSN. Alternatively, RANAP SGSN functionality may be split between SGSN and RNC, RANAP and user plane signals may be relayed by the first base station controller to the second base station controller, and the first base station controller may act as an anchor.

Arrangement and method for radio network relocation

A wireless access network system comprises a RADIUS (Remote Access Dial-In User System) arrangement with an associated RADIUS accounting function. The RADIUS arrangement is arranged to track access activity by a user accessing the network via wireless user equipment and via the RADIUS arrangement. The access activity is recorded in an accounting database which is associated with the RADIUS accounting function. The wireless access system also comprises a radio network controller which comprises a RADIUS client. The RADIUS arrangement is arranged to receive information from a radio network controller of the system in order to track the access activity. The Invention is applicable to cellular communication systems such as UMTS (Universal Mobile Telecommunication System).

Use of radius in UMTS to perform accounting functions

Controlling packet sessions and QoS in a wireless network is disclosed. An apparatus provides application-specific packet sessions in the wireless network, with application-specific QoS parameters, without requiring the explicit cooperation of an application.

Controlling QoS in a wireless apparatus

An arrangement and method for session control in a wireless UMTS radio access network () by performing creation and deletion of application-specific packet sessions (PDP contexts) in the network, with application-specific QoS parameters, without requiring the explicit cooperation of the application software (either via software API or modem AT command). This allows session set-up and tear-down control of dedicated packet sessions for particular data services, in a UMTS 3G mobile wireless network, with application-specific QoS parameters, with umodified applications operating over the network.

Arrangement and method for session control in wireless communication network

Internet web technology is used to allow a wireless Internet customer to acquire a virtual subscriber identity module (VSIM) in an anonymous session connection and then transfer the VSIM to any other desired PC (personal computer).
