    Abstract: A packet-switched Base Station System (200) transmission infrastructure is disclosed, whereby statistical multiplexing can be used to improve the utilization of installed transmission resources. In such a packet-based network, all types of traffic (e.g., signalling, speech, Circuit-Switched Data and GPRS traffic) can be mixed because efficient mechanisms are made available for assuring that Quality of Service requirements are met. As such, the mixing of speech and data traffic with their different Quality of Service requirements is made especially efficient by the infrastructure (200) disclosed. Notably, the infrastructure (200) disclosed can be implemented for any Internet Protocol-(IP-)based Random Access Network (RAN), and in particular (but not exclusively), can be implemented for TDMA and Code Division Multiple Access (CDMA) systems.

    Abstract: A Radio Access Network (RAN) (10) and method for rapid handover of a mobile station between a Source Radio Network Controller (SRNC) (12) and a Target Radio Network Controller (TRNC) (21) in the RAN. A mobile station (16) initially served by the SRNC accesses an Enhanced General Packet Radio Service (EGPRS) network (27) through the RAN for conducting a packet-switched call. When handover to the TRNC is required, the SRNC notifies the TRNC that relocation of the mobile station to the TRNC is requested. The TRNC reserves radio resources required to serve the mobile station in the TRNC, and notifies the SRNC that relocation is approved. An Iux interface (11) may be established between the SRNC and the TRNC for direct communication of control signaling. Alternatively, the control signaling between the SRNC and the TRNC may pass through the EGPRS network. The EGPRS begins bi-casting Packet Data Units (PDUs) (44) to both the SRNC and the TRNC until notified by the TRNC that the handover is complete (45). The mobile station is then handed over to the TRNC, and the EGPRS network is notified by the TRNC that the handover is complete. With the Iux interface (11), control signaling that is specific to the RAN does not have to be passed through the EGPRS network.

    Abstract: The present invention relates to packet-distributed data transmission of compressed data. According to the invention, parity bits are supplied to the compressed data. The parity bits are used in the entire transmission chain between an encoder having compressed the data, and a decoder which decompresses it. According to one embodiment, the data is speech and the packet-distributed network is a mobile radio network with packet-distribution in included links. However, sending in the radio link of the compressed speech is circuit switched.

    Abstract: A method for protecting the transmission of network independent clocking and status information over an air interface (20) between a mobile station (10) and base transceiver station (15) is disclosed. The method involves defining a parallel logical channel (35) between the mobile station (10) and base transceiver station (15) to carry network independent clocking (50) and status information. The network independent clocking (50) and status information are removed from the data stream (90) of the traffic channel (25) and transmitted on the parallel channel (35) over the air interface (20). Alternatively, a buffer (79) may be used in conjunction with or singly to process the data stream (90) of the traffic channel (25) to delete or insert bits or characters to minimize or eliminate the need for network independent clocking information (50).

    Abstract: A base station subsystem (BSS) and method is provided that handles an increase in traffic volume which temporarily overloads at least one terrestrial link in an IP network by gracefully downgrading the transmission rate of one or more calls. More specifically, the BSS includes a base station transmitter (BTS), an IP gateway and an IP network which passes at least one packet based call on a terrestrial link between the BTS and the IP gateway. The BTS and IP gateway each include an end-point having a buffer for measuring a delay in passing the at least one packet based call through the terrestrial link of the IP network and for downgrading a service when the delay as measured by one of the buffers exceeds a predetermined value.

    Abstract: A RATIO ACCESS NETWORK (RAN) AND METHOD FOR RAPID HANDOVER OF A MOBILE STATION BETWEEN A SOURCE RADIO NETWORK CONTROLLER (SRNC) AND A TARGET RADIO NETWORK CONTROLLER (TRNC) IN THE RAN. A MOBILE STATION INITIALLY SERVED BY THE SRNC ACCESSES AN ENHANCED GENERAL PACKET RADIO SERVICE (EGPRS) NETWORK THROUGH THE RAN FOR CONDUCTING A PACKET-SWITCHED CALL. WHEN HANDOVER TO THE TRNC IS REQUIRED, THE SRNC NOTIFIES THE TRNC THAT RELOCATION OF THE MOBILE STATION TO THE TRNC IS REQUESTED. THE TRNC RESERVES RADIO RESOURCES REQUIRED TO SERVE THE MOBILE STATION IN THE TRNC, AND NOTIFIES THE SRNC THAT RELOCATION IS APPROVED. AN IUX INTERFACE MAY BE ESTABLISHED BETWEEN THE SRNC AND THE TRNC FOR DIRECT COMMUNICATION OF CONTROL SIGNALING. ALTERNATIVELY, THE CONTROL SIGNALING BETWEEN THE SRNC AND THE TRNC MAY PASS THROUGH THE EGPRS NETWORK. THE EGPRS BEGINS BI-CASTING PACKET DATA UNITS (PDUs) TO BOTH THE SRNC AND THE TRNC UNTIL NOTIFIED BY THE TRNC THAT THE HANDOVER IS COMPLETE. THE MOBILE STATION IS THEN HANDED OVER TO THE TRNC, AND THE EGPRS NETWORK IS NOTIFIED BY THE TRNC THAT TH HANDOVER IS COMPLETE. WITH THE IUX INTERFACE, CONTROL SIGNALING THAT IS SPECIFIC TO THE RAN DOES NOT HAVE TO BE PASSED THROUGH THE EGPRS NETWORK.FIGURE 3
