Method and system for regulating autonomous messaging by subscriber units in a wireless communication network

A wireless communication network generally includes a number of subscriber units, a base station controller, and a base station transceiver coupled to the base station controller. A parameter specifying an interval at which subscriber units in the wireless communication network are permitted to generate autonomous messages is stored, for example, in a system parameter database at the base station. The parameter is broadcast by the base station transceiver over-the-air to subscriber units in the wireless communication network. In response to receipt of the parameter, the subscriber units store the parameter and thereafter transmit autonomous message over-the-air only in accordance with the parameter. In one preferred embodiment, the parameter regulates how often autonomous messages can be transmitted by individual subscriber units. Alternatively or additionally, the parameter can be used to ensure that the subscriber unit is in a stable state before an autonomous message is transmitted by ...

用于混合移动终端的方法和装置

... 构造接入网控制器和基站控制器以定义它们之间的接口，使这两个系统能够实现并响应将要建立的到混合移动台的语音呼叫，即使混合移动台目前为纯数据呼叫占用。更具体地讲，基站被构造为生成到接入网控制器的伪寻呼信号，从而在基站生成寻呼信号以建立语音呼叫之前确定混合移动台是否存在且可用。根据从接入网控制器接收的响应，基站要么寻呼混合移动台以建立语音呼叫，将呼叫转发至语音邮件，要么将呼叫转发至因特网呼叫传送服务器或因特网呼叫等待服务器。 ...

Method and apparatus for a hybrid mobile terminal

An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Method and apparatus to control handoff between different wireless systems

A wireless communications network includes a first base station system that performs wireless communications according to a first protocol (e.g., 1xEV-DO protocol) and a second base station system that performs wireless communications according to a second, different protocol (e.g., IS-2000). A link is provided between the first and second base station systems to enable a network-initiated handoff procedure. If a source base station system detects that a handoff of a mobile station to a target base station system is required, the source base station system exchanges messaging over the link with the target base station system to perform the handoff. In one example, the handoff is a hard handoff.
