Abstract
An apparatus and method for managing a Random Access CHannel (RACH) in a mobile communication system, in which a User Equipment (UE) receives a UE information transmit request for a RACH procedure from a network, and transmits, to the network, a message including information indicating a contention detected in the RACH procedure.
Claims22
A Random Access CHannel (RACH) management method performed by a User Equipment (UE) in a mobile communication system, comprising:
- determining successful completion of a RACH procedure when a contention resolution is received before a contention resolution timer expires;
- receiving a UE information transmit request from a network, upon the successful completion of the RACH procedure;
- and
- transmitting, to the network, a message including contention information of the completed RACH procedure, in response to the UE information transmit request.
A method for managing a Random Access CHannel (RACH) by a network in a mobile communication system, comprising:
- determining successful completion of a RACH procedure when a contention resolution is received before a contention resolution timer expires;
- transmitting a User Equipment (UE) information transmit request, to a UE, upon the successful completion of the RACH procedure;
- and
- receiving, from the UE, a message including contention information of the completed RACH procedure, in response to the UE information transmit request.
A User Equipment (UE) apparatus using a Random Access CHannel (RACH) in a mobile communication system, comprising:
- a receiver for determining successful completion of a RACH procedure when a contention resolution is received before a contention resolution timer expires, and receiving a UE information transmit request from a network, upon the successful completion of the RACH procedure;
- and
- a transmitter for transmitting, to the network, a message including contention information of the completed RACH procedure, in response to the UE information transmit request.
A network apparatus for managing a Random Access CHannel (RACH) in a mobile communication system, comprising:
- a receiver for determining successful completion of a RACH procedure when a contention resolution is received before a contention resolution timer expires;
- a transmitter for transmitting a User Equipment (UE) information transmit request, to a UE, upon the successful completion of the RACH procedure;
- and
- a receiver for receiving, from the UE, a message including contention information of the completed RACH procedure, in response to the UE information transmit request.
