    Abstract: An apparatus and method of effecting hand-off of a mobile station (104) in a first wireless communication system, which has a first mobile switching node (204) operable with a first base station (208) and a second mobile switching node (220) operable with a second base station (224), and a second wireless communication system, is claimed. A handoff required message (404) is received at the first mobile switching node (204) and sent (408) to a second mobile switching node (220). A message (412) from the second mobile switching node is sent to request allocation for a handoff. In an embodiment, this message (412) is sent to the VLR of the second wireless communication system. In response, a handoff request acknowledge message (428) is received by the second mobile switching node (220) and sent to the first mobile switching node (204). An initial address message (432) is sent to initiate a circuit connection between the first mobile switching node (204) and the second mobile switching node (220). Then, the call is received from the first mobile switching node (204).

    Abstract translation: 一种在第一无线通信系统中实现移动台（104）越区切换的设备和方法，该设备和方法具有可与第一基站（208）和第二移动交换节点（220）一起操作的第一移动交换节点（204） ）可与第二基站（224）一起操作，以及第二无线通信系统。 在第一移动交换节点（204）处接收到切换请求消息（404）并将其发送（408）到第二移动交换节点（220）。 发送来自第二移动交换节点的消息（412）以请求分配用于切换。 在一个实施例中，该消息（412）被发送到第二无线通信系统的VLR。 作为响应，切换请求确认消息（428）由第二移动交换节点（220）接收并发送到第一移动交换节点（204）。 发送初始地址消息（432）以发起第一移动交换节点（204）和第二移动交换节点（220）之间的电路连接。 然后，从第一移动交换节点（204）接收该呼叫。

    Abstract: A method of authenticating a mobile station (18) from a first base station (12) in a first cellular communications system controlled by a first mobile switching control station (10) to a second base station (14) 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.

    Abstract: A method for enabling a mobile telephone to operate in a communications network, including: generating a random authentication number and an expecte d response to the random authentication number, and transmitting a forward sho rt message service (SMS) message incorporating the random authentication number to the mobile telephone. The method further includes generating at the mobil e telephone, responsive to the random authentication number, an authentication response, and receiving from the mobile telephone a return SMS message incorporating the authentication response. The method also includes performi ng a comparison between the authentication response in the return SMS message a nd the expected response, and authenticating the mobile telephone to operate in the communications network responsive to the comparison.
