Abstract:
A communication system including a mobile sending a plurality of uplink radio link control data blocks (328, 332, 336, 340) to a base station in an uplink temporary block flow and receiving a plurality of downlink radio link control data blocks (326, 330, 334, 338, 342) from the base station in a downlink temporary block flow. A GPRS/EDGE subsystem having a mobile station medium access control layer is located in the mobile and communicates with a protocol control unit having a base station medium access control layer in the base station.

Abstract:
A terminal 300 arranged to initiate a call or indicate an incoming call with a voiced alert and methods thereof, the terminal including a receiver 303 for receiving a signal corresponding to a call alert, a processor 309 for determining that the signal is a call alert signal corresponding to the voiced alert and for providing an alert signal corresponding to the voiced alert; and an audio transducer 317 coupled to the alert signal corresponding to the voiced alert for generating a user perceptible voiced alert. The terminal for initiating includes an audio transducer 321 for converting a caller party voiced signal to an alert signal and a processor 309 for generating a call alert signal corresponding to the alert signal; and a transmitter 305 for sending the call alert signal corresponding to the alert signal to a network and thereby to the called party.
Abstract:
An access point ( 102 ) conveys ( 202 ) to communication units ( 104 ) of a plurality of multicast groups, a first indication that the access point supports a method for sending a multicast message. The access point receives ( 204 ) a multicast message directed to a receiving one of the plurality of multicast groups, and determines ( 206 ) that the communication units belonging to the receiving one of the plurality of multicast groups also support the method. The access point signals ( 208 ) a second indication to selectively awaken the communication units belonging to the receiving one of the plurality of multicast groups, and transmits ( 210 ) the multicast message to the receiving one of the plurality of multicast groups in a manner that allows ( 212 ) at least one communication unit not belonging to the receiving one of the plurality of multicast groups to remain asleep during the transmitting.
Abstract:
A communication system including a mobile station ( 202, 322 ) sending a plurality of uplink radio link control data blocks ( 328, 332, 336, 340 ) to a base station ( 208, 320 ) in an uplink temporary block flow ( 248 ), and receiving a plurality of downlink radio link control data blocks ( 326, 330, 334, 338, 342 ) from the base station in a downlink temporary block flow ( 225 ). The communication system includes a protocol control unit ( 214 ) within the base station, having a base station medium access control layer ( 213 ) that sends an identifier during setup of the downlink temporary block flow ( 224 ), and sends an uplink state flag indicating channel availability in a first one of the plurality of downlink radio link control data blocks ( 326 ). A GPRS/EDGE subsystem ( 210 ) is located within the mobile station, having a mobile station medium access control layer ( 211 ) that receives the identifier and the uplink state flag, and sends uplink data in a first one of the plurality of uplink radio link control data blocks ( 32 ) to the base station in response to the uplink state flag indicating channel availability. The base station medium access control layer sends a directed acknowledgement in a subsequent one of the plurality of downlink radio link control data blocks ( 330 ) in response to receipt of the uplink data from the mobile station, and the mobile station sends uplink data in a second one of the plurality of uplink radio link control data blocks ( 332 ) in response to the directed acknowledgement.
