摘要： 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.

摘要： The present invention relates to a mobile communication system supporting communication of data which comprises a base station communicating with a switching arrangement. A communication protocol is used for communication between a mobile station and the switching arrangement. The connection between the base station and the switching arrangement supports packet switched communication and detecting means are provided in the base station to detect if data frames sent from the mobile station are correctly received over the air interface. Means are also provided for sending only data frames detected as correctly received on to the switching arrangement using the packet switched connection between the base station and the switching arrangement.

摘要： 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).

摘要： A method and system are provided for optimal routing of calls in an Internet Protocol-based Base Station System (IP-based BSS) (200), whereby a plurality of new messages are introduced on the A-interface. One such message informs the BSS (200) that the Circuit Identity Codes (CICs) included in the message can be connected to the BSS (200) to provide optimal routing of one or more calls. Another such message informs the BSS (200) that the CICs included in the message are to be restored as separate CICs on the A-interface. The provision of such messages overcomes the significant disadvantages of the existing and developing BSS implementations.

摘要： 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.

摘要： A synchronization frame is first formated and transmitted in accordance with the Global System for Mobile (GSM) 08.60 specification. After an initial synchronization procedure is accomplished between a transcoder/rate adaptor (TRAU) (40) and a particular base transceiver station (BTS) (50) serving a mobile station (60), a modified GSM 08.60 frame is thereafter used to transport greater user data payload across the established communications link. The modified frame replaces the synchronization bits included in the GSM 08.60 formatted data frame with user data to increase data payload from the conventional 13.5 Kbit/s to a more desirable 14.4 Kbit/s without altering the standardized 16 Kbit/s transmission rate supported by the IWF and the BTS (50).

摘要： The present invention relates to the technique of handover in mobile telephony. A new Transcoder and Rate Adaptation Unit (100, fig. 3) is introduced which provides two uplink (230, 250 respectively, fig. 3) and two downlink (240, 260 respectively, fig. 3) channels. The use of these two channels (230, 250 respectively, fig.3) on the uplink during handover provides for the use of distributed handover on the uplink. The result minimizes the audible interruption during handover by minimizing the loss of Traffic Channel frames to what is possible within the GSM standard. Additionally, interruption of the speech or background noise during these lost frames is masked by an error concealment algorithm, since the Transcoder and Rate Adaptation Unit (100, fig. 3) still has information from the Base Transceiver Station responsible for transmission before the handover.
