    摘要: An apparatus and method of effecting hand-off of a mobile station in a first wireless communication system, which has a first mobile switching node operable with a first base station and a second mobile switching node operable with a second base station, and a second wireless communication system, is claimed. A handoff required message is received at the first mobile switching node, and sent to a second mobile switching node. A message from the second mobile switching node is sent to request allocation for a handoff. In an embodiment, this message is sent to the VLR of the second wireless communication system. In response, a handoff request acknowledge message is received by the second mobile switching node and sent to the first mobile switching node. An initial address message is sent to initiate a circuit connection between the first mobile switching node and the second mobile switching node. Then, the call is received from the first mobile switching node.

    摘要: A method of effecting handoff of a mobile station from a first base station in a first cellular communications system controlled by a first mobile switching control station to a second base station in a second, different cellular system controlled by a second mobile switching control station is described. The method comprises generating at the second cellular communication system an authentication code as the result of applying an algorithm to a private key assigned to the mobile station for the second cellular communications system and a random number generated by the second cellular communications system. An authentication code is also generated at the first cellular communication system as the result of applying an algorithm to the private key and the random number. The authentication code generated at the first cellular communication system is then transmitted to a mobile station in a data packet, and, from there, the authentication code is transmitted to the second cellular communication system. The authentication code generated at the first cellular communications system is then compared with the authentication code generated at the second cellular communications system.

    摘要: A method of effecting handoff of a mobile station from a first base station in a first cellular communications system controlled by a first mobile switching control station to a second base station in a second, different cellular system controlled by a second mobile switching control station is described. The method comprises measuring at the mobile station a parameter of a signal transmitted by said first base station and a parameter of a signal transmitted by said second base station. When the parameters reach a predetermined condition, a signal quality message is communicated from the mobile station via the first base station to said first mobile switching control station, which responds by generating information for a channel request message for the second mobile switching control station and transmitting the same to the mobile station. The mobile station generates from the information a channel request message for the second mobile switching control station and transmits the same to the second mobile switching control station. The second mobile switching control station generates channel information identifying a channel in the second communications system for the mobile station so that the handoff may be effected.

    摘要: A system and method are provided for supporting a multi-mode portable user terminal (UT) hard handoff procedure for a call from a wireless local area network (WLAN) to a cellular telephone network. The method includes: establishing a link between a UT and a serving WLAN; establishing a call via the established WLAN link; monitoring the WLAN link signal strength; simultaneously monitoring a serving cellular network; initiating a hard handoff to the cellular network, responsive to the monitored WLAN link signal strength falling below a minimum threshold; and, continuing the call via the cellular network. More specifically, the method initiates a call handoff to a Cellular Gateway (CGW) telephone number, responsive to the monitored WLAN link signal strength falling below the minimum threshold. Then, continuing the call via the cellular network includes continuing the call to the first telephone number via the CGW handoff telephone number.

    摘要: A GSM1×-to-GSM handoff feature allows a GSM1× subscriber with a dual-mode (GSM1× and GSM modes) handset to seamlessly roam from GSM1× coverage areas to GSM coverage areas. This functionality is facilitated by the GSM1× system design which integrates a CDMA RAN with a standard GSM core network. The GSM1× system is built using standard CDMA as its air interface and an unmodified CDMA RAN with a standard IOS interface to the MSN. The only modifications are done at the MSN and the MS.
