摘要:
Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Bandwidth in the second (or third) time slot can be used to carry information in a fast out-of-band channel (FOC). The FOC may provide information relating to the same connection as the payload or data field in that time slot, e.g., a service type identifier which informs the mobile or base station of the type of information (e.g., voice, video or data) being conveyed in the payload. Alternatively, the FOC information may be associated with a connection or connections which are different from that supported by the payload or data field containing the FOC.

Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate. Moreover, FACCH information need only be transmitted in the master channel.

摘要:
A method for reassigning mobile stations a new phase within a channel is disclosed. In a communication system, a plurality of mobile stations attempt to communicate on a limited number of channels. The invention first uses a general allocation method to approximately evenly distribute the mobile stations on the available channels. After a mobile station begins active communication on the system, a second allocation method is used to change the phase of some mobile stations on a channel which has become heavily loaded. In addition, a message can also be sent to mobile stations assigned to but not yet actively communicating on the heavily loaded channel indicating that the mobile stations should change to a new channel.
摘要:
A method for increasing throughput capacity of a mobile station transmitting a plurality of consecutive bursts to a base station in a communication system is disclosed. The first burst is transmitted using a normal burst format while succeeding consecutive bursts are transmitted using an auxiliary burst format wherein the auxiliary bursts contain larger data fields than normal bursts.

A method for paging mobile stations in a communication system with a packet data control channel which is subdivided into master slots and slave slots is disclosed. First, each mobile station is assigned a paging slot, wherein the paging slot is a master slot. The system then pages one of the mobile stations on the paging slot assigned to the mobile station.

A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.
摘要:
A method for registering a mobile station when the mobile station first enters a communication system which supports packet data channels is disclosed. The mobile station receives system information broadcasted on a digital control channel. The mobile station is then assigned to a beacon packet data channel over which the mobile station registers with the communication system.

A radiocommunication system supports multi-user multiplexing. Half rate data communications with interleaving of data between two sources are described.
摘要:
A communication system includes a politeness zone (PZ); a wireless communication device configured to receive incoming communications over a first communication channel and politeness requests over a second communication channel, the communication device comprising an alerting mechanism configured to indicate receipt of an incoming communication over the first communication channel, the alerting mechanism operable in a politeness mode and a non-politeness mode, the politeness requests indicating that operation of the alerting mechanism should be set to politeness mode, wherein, upon receipt of a politeness request over the second communication channel, the device is configured to accept the politeness request and set operation of the alerting mechanism to politeness mode, or to reject the politeness request and leave operation of the alerting mechanism in its present mode of operation; and a politeness zone transmitter (PZT) configured to send politeness requests to the communication device over the second communication channel when the communication device is proximate the PZ.
