摘要： A method and system are provided for synchronizing wireless communication devices. The method and system involve providing a first unit and a second unit for communication over a wireless communication link. Further, an identical identifier is assigned to the first and second units. Also, a data message is constructed having control data. The data message includes a plurality of data bytes and a portion of the control data corresponds to the identifier. The data message is split into a plurality of message portions and the message portions are transmitted from the first unit to the second unit. The message portions are received at the second unit. Control data from the message portions is assembled to form a control message at the second unit. The identifier portion of the control message is compared with the identifier assigned to the second unit. When the identifier portion of the control message matches the identifier assigned to the second unit, the second unit enters an in-synchronization state. When the identifier portion of the control message is different from the identifier assigned to the second unit, the second unit enters an out-synchronization state. At least one prior control message is searched for the identifier assigned to the second unit when the second unit is in the out-synchronization state. A matching identifier is synchronized with when the matching identifier is found in the prior control messages. When the prior control messages are free of the identifier, the second unit resynchronizes with the first unit.

摘要： A method and system are disclosed for avoiding bad frequency subsets in a frequency hopping cordless telephone system. A base station communicates with the handsets using frequencies selected from active frequency subsets. Bad frequency subsets are avoided by monitoring the air interface between the base station and handsets for errors in active frequency subsets. Errors in each active frequency subset are counted during a short-term interval using an associated short-term error counter and during a long-term interval using an associated long-term error counter. After each short-term interval, it is evaluated whether any of the short-term error counters has a value that is greater than a defined threshold. After each long-term interval, it is evaluated whether any of the long-term error counters has a value greater than an error count for a blocked frequency subset. A blocked frequency subset is then substituted for an active frequency subset if an associated short-term error counter is greater than the defined threshold or if a long-term error counter is greater than the error count for a blocked frequency subset.

摘要： A method and system are disclosed for shifting frequency subsets to avoid base station interference in a frequency hopping cordless telephone system. A base station communicates with the handsets using frequencies selected from active frequency subsets. Frequency subsets are shifted to avoid interference by selecting frequencies initially from a defined number of active frequency subsets where each of the active frequency subsets is used before repeating an active frequency subset. The number of active frequency subsets is then changed for a defined period of time to change the period with which the active frequency subsets are used. After the defined period of time, the number of active frequency subsets is returned to the defined number of active frequency subsets.

摘要： A system and method for call screening in a wireless telephone system. When a call is received on an answering machine (17) associated with a base part (11), the user at a portable part (12) may select a call screen button (19). The resulting signal is received at the base part (11), which then enters a broadcast mode. The incoming answering machine message is broadcast to all handsets (12, 14, 16). In a TDMA system, an audio message is broadcast from a base part (11) during a single time slot of a time division. The user at a particular portable part may then select a pick up button to pick up the call.

摘要： A frequency hopping spread spectrum telecommunication system is provided, which selects carrier frequencies based on the number of active slots. The duration that carriers have been employed is then based on the number of active slots (401, 402), rather than the number of frames (22). Thus, non-interfered with carriers can be used more often than interfered with carriers, thereby improving voice quality.

In steps two, the parameters for each of the individual communication links (14a-17a) are evaluated to determine the optimum quality for each link. In step three, transmission attributes are selected in response to the evaluated parameters to optimize the transmission quality of each link.
