First Claim
1. A wireless base station device arranged to handle wireless communication between a plurality of associated wireless terminals (T1, T2, T3) and an IP network, the device comprising:
- a radio transceiver (RT) arranged to wirelessly communicate with the plurality of wireless terminals (T1, T2, T3),a network interface (NI) arranged to communicate with the IP network, anda processor with software arranged to implementa communication application, anda communication session management (CSM) for controlling sessions of communication with the plurality of associated wireless terminals (T1, T2, T3),wherein the communication session management (CSM) is arranged to control a communication session with an associated wireless terminal (T1, T2, T3), while wireless radio frequency communication with said associated wireless terminal (T1, T2, T3) involved with said communication session is handled by an associated external device (B2, B3),wherein a lower layer (LL) comprises the radio transceiver (RT), wherein an upper layer (UL) comprises the communication application and the communication session management (CSM), wherein the device comprises a routing layer (RL) serving to separate the lower layer (LL) and the upper layer (UL) so as to allow the upper layer (UL) to handle communication sessions with associated lower layers (LL) physically separate from the upper layer (UL) and, wherein the radio transceiver (RT), the network interface (NI) and the processor are housed within one single casing.

Abstract
Wireless base station device for handling wireless communication, e.g. DECT, between a plurality of associated wireless terminals and an IP network. The base station device has a radio transceiver, a network interface, and a processor with communication application and a communication session management software. The communication session management is arranged to control a communication session with an associated wireless terminal (upper layer management), while wireless communication with said associated wireless terminal involved with said communication session (lower layer) is handled by another base station device. Thus, the base station can manage separate operation of its upper and lower layer, thereby enabling e.g. hand-over of a session to and from other base stations. This allows self contained single casing base station devices to operate in a network without the need for at central server, and still such network is easy to extend by adding base stations.
