The base station apparatus according to the present invention places pilot data and transmission power control data independently of each other in a slot based on processing delays and propagation delays required for transmission power control and places slots by providing an offset for the slot locational relationship between the uplink and downlink. ses RTP (real time protocol) media, wherein the target gateway comprises an RTP handling unit and wherein said default frame generator comprises a portion of the RTP handling unit. 12. In the radio communication system of claim 1 wherein the communication system further comprises at least a third communication station, wherein the mobile station formed of the first communication station is operable in a multi-communication mode permitting concurrent communication sessions between the mobile station and the second communication station and between the mobile station and the third communication station, at least a selected one of the concurrent communication sessions in an inactive state when the effectuation of the subsequent communication through the target gateway occurs, a further improvement of apparatus for the at least one of the second and at least third communication stations, respectively, with which the communication session with the mobile station is in the inactive state, said apparatus for facilitating uninterrupted communications when the communication session between the mobile station and the at least the selected one of the second and at least third communication stations returns to an active state, said apparatus comprising: a timer located at least at the selected one of the second and at least third communication stations in the inactive state when the effectuation of the subsequent communication occurs, said timer for timing periods of absence of incoming data during the communication session with the mobile station, said timer for generating a request to alter communication session parameters if a timed period of the absence of incoming data exceeds a selected time period. 13. The apparatus of claim 12 wherein the packet-formatted data comprises RTP (real time protocol) media, wherein the at least one selected of the second and at least third communication stations having the communication session in the inactive state further comprises an RTP handling unit and wherein said timer forms a portion of the RTP handling unit. 14. In a radio communication system operable to permit concurrent communication of packet-formatted data between a mobile station and a second communication station and between the mobile station and a third communication station, the packet-formatted data communicated by way of a communication network having a radio part and a wireline part and the communication network including a source gateway through which communications are initially effectuated and a target gateway through which communications are subsequently selected to be effectuated, at least a selected one of the concurrent communication sessions in an inactive state when the effectuation of the subsequent communication through the target gateway occurs, an improvement of apparatus for the at least the selected one of the second and at least third communication stations, respectively, having the communication session in the inactive state, said apparatus for facilitating uninterrupted communications when the communication sessions between the mobile station and the at least the selected one of the second and at least third communication stations, having the communication session in the inactive state, returns to an active status, said apparatus comprising; a timer located at the at least the second one of the second and at least third communication stations, said timer for timing periods of absence of incoming data during the communication session with the mobile station, said timer for generating a request to alter communication session parameters if a timed period of the absence of incoming data exceeds a selected timer period. 15. In a method for communicating packet-formatted data between a first communication station and a second communication station by way of a communication network having a radio part and a wireline part, the first communication station forming a mobile station, and the communication network i ncluding a source gateway through which communications are initially effectuated and a target gateway through which communications are subsequently selected to be effectuated, an improvement of a method for the target gateway for informing the second communication station of selection of target gateway for effectuation of subsequent communications therethrough, said method comprising: providing to the target gateway indications of selection of the target gateway through which to effectuate the subsequent communications; generating a default frame at the target gateway responsive to the indications provided to the target gateway during said operation of providing, the default frame identifying the target gateway; and transmitting the default frame to the second communication station, thereby to inform the second communication station of the target gateway for the effectuation therethrough of the subsequent communications. 16. The method of claim 15 wherein the indications of selection provided to the target gateway during said operation of providing comprise uplink data generated by the mobile terminal. 17. The method of claim 16 comprising the additional operation of determining whether the uplink data generated by the mobile terminal and provided to the target gateway in valid data. 18. The method of claim 17 comprising the additional alternative operations of: forwarding on the uplink data to the second communication station if the uplink data is determined to be valid data; otherwise substituting each uplink data frame of the uplink data determined to be invalid with a default data frame. 19. The method of claim 15 wherein the default frame generated during said operation of generating comprises a SID (silence indication) frame. 20. The method of claim 17 comprising the additional operations of: timing, at the second communication station absence of incoming data from the mobile station; and generating a request to alter communication session parameters if a timed period of the absence of the incoming data exceeds a selected time period. es available to a wide range of users.
