A method and device are provided for of supporting a plurality of mobile station operation modes in a wireless communication system by user control. Presently, communication protocols exist for supporting end user equipment which operates in a single mode of operation. However, it is desirable to combine protocols from various technologies to form end user equipment which operates in multiple modes of operation. Thereby, the present method allows the mobile station to operate in a multi-mode environment where a user can invoke a certain mode.

Operating mobile stations of wireless communication systems in multiple

A method is disclosed for improving the efficiency of the packet data channel by providing means for interrupting tranmsissions so as to allow a communication system to send a short message to a different mobile station. The packet channel feedback information includes several flags: Busy-Reserved/Idle (BRI); Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.

Packet channel feedback

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.

Method for increasing throughput capacity in a communication system

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.

Activity control for a mobile station in a wireless communication system

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.
