Method for requesting resource based on timer in mobile telecommunication systems
View Patent ↗Provided is a timer-based resource requesting method in a mobile telecommunication system. The resource requesting method includes the steps of: a) waiting in a waiting mode for an event to occur while a timer of a terminal operates; b) transmitting scheduling information including information on a quantity of packets existing in a terminal buffer to a base station when operation of the timer ends at a predetermined threshold time; and c) initializing the timer.
1. A timer-based resource requesting method in a mobile telecommunication system, comprising:
waiting in a waiting mode for an event to occur while a request timer of a terminal operates;
determining whether a service data unit exists in a terminal buffer when operation of the request timer ends at a predetermined threshold time;
transmitting scheduling information including information on a quantity of packets existing in the terminal buffer from the terminal to a base station when the service data unit exists; and
resetting the request timer and returning to the waiting mode, wherein the resetting the request timer comprises:
resetting the request timer when the service data unit does not exist; and
resetting the request timer after transmitting the scheduling information when the service data unit exists.
2. The resource requesting method of claim 1 , wherein the scheduling information is transmitted based on a random access message.
3. The timer-based resource requesting method of claim 1 , further comprising:
waiting in a waiting mode for an event to occur while a query timer of a base station operates;
receiving a random access message including the scheduling information from the terminal; and
resetting the query timer and returning to the waiting mode.
4. A timer-based resource requesting method in a mobile telecommunication system, comprising:
waiting in a waiting mode for an event to occur while a request timer of a terminal operates;
receiving a query from a base station;
determining whether a service data unit exists in a terminal buffer;
transmitting scheduling information from the terminal to the base station based on resource allocation information of the query when the service data unit exists;
transmitting buffer empty information to the base station when determining that the service data unit does not exist; and
resetting the request timer and returning to the waiting mode, wherein the resetting the request timer comprises:
resetting the request timer after transmitting the scheduling information when the service data unit exists; and
resetting the request timer after transmitting the buffer empty information when the service data unit does not exist,
wherein the query includes uplink resource allocation information for transmitting the scheduling information.
5. The timer-based resource requesting method of claim 4 , further comprising:
waiting in a waiting mode for an event to occur while a query timer of a base station operates;
transmitting the query to the terminal when operation of the query timer ends at a predetermined threshold time; and
resetting the query timer and returning to the waiting mode.
