摘要： A method and apparatus allocates a first predetermined plurality of frame time slots (102) to a first protocol, and allocates a second predetermined plurality of frame time slots (102) to a second protocol having a base frame management capability. The base frame management capability is applied such that portable selective call receiving devices (10) utilizing the second protocol normally perform battery saving throughout the first predetermined plurality of frame time slots (102).

摘要： A selective call receiving device (10) such as a pager is controlled to dynamically change a base frame assigned to the device and subsequent control frames derived therefrom. The time that the device is operative to look for its address in a received signal can thus be dynamically changed to improve the efficiencies of a mixed systems environment without substantially reducing the battery life of the selective call receiving device (10). In two embodiments of the invention a new base frame for the device is derived from an originally assigned base frame that is stored in the selective call receiving device. In another embodiment, a new base frame for the device is derived from the device's address along with frame management information that is received by the selective call receiving device.
摘要翻译：控制诸如寻呼机的选呼接收设备（10）动态地改变分配给设备的基本帧和从其导出的后续控制帧。因此，可以动态地改变设备在接收信号中寻找其地址的时间，以提高混合系统环境的效率，而不会显着降低选呼接收设备（10）的电池寿命。在本发明的两个实施例中，用于设备的新的基本帧从存储在选择呼叫接收设备中的原始分配的基本帧导出。在另一个实施例中，从设备的地址以及由选择呼叫接收设备接收到的帧管理信息导出用于设备的新的基本帧。

摘要： A communication system (100) providing analog message re-transmission on demand comprises a base station (114) and at least one portable communication transceiver (118). The base station (114) transmits an address (414) identifying the portable communication transceiver (118) to which a voice message is directed, and a session number (415) modulated in a first modulation format and a compressed analog message (418) representing the voice message modulated in a second modulation format. When the signal quality of the voice message played back in the portable communication transceiver (118) is perceived by the user to be unintelligible, the user can receive from the base station (114) a re-transmission of the compressed analog message (418) by generating a request for re-transmission of the compressed analog message (418).
摘要翻译：根据需要提供模拟消息重传的通信系统（100）包括基站（114）和至少一个便携式通信收发器（118）。基站（114）发送识别语音消息所针对的便携式通信收发信机（118）的地址（414）和以第一调制格式调制的会话号码（415）和代表以第二调制格式调制的语音消息。当在便携式通信收发器（118）中回放的语音消息的信号质量被用户感知为不可理解时，用户可以从基站（114）接收压缩的模拟消息（418）的重新发送，通过产生对所述压缩模拟消息的重传的请求（418）。
