Abstract:
A handover control device in heterogeneous access systems and a method thereof are provided to enable a 3GPP(3rd Generation Partnership Project)-based advanced mobile communication network consisting of plural access systems to determine handover of a terminal on the basis of the handover policy of an access system to which the handover will be performed, thus handover between heterogeneous access systems is effectively executed. A PCRF(Policy and Charging Rule Function)(220) receives a request for handover to the second access system(AF/SPR(Application Function/Subscriber Profile Repository))(230) from the first access system(Inter-AS(Access System) MM(Mobility Management))(210)(S201-S207). Based on a handover policy of the second access system(230), the PCRF(220) checks handover possibility for at least one service provided from the first access system(210)(S211-S213). The PCRF(220) determines a policy rule to be applied to the handover-possible service to deliver the determined rule to the second access system(230)(S215-S219). The handover request is acknowledged to a terminal(10)(S221).

Abstract:
PURPOSE: A method for recognizing a data transmission request of a terminal/base station RRC(Radio Resource Control) using a network transmission unit is provided to effectively use a radio resource by using a message mutual transmission between a terminal/base station RLC(Radio Link Control) or PDCP and RRC which can recognize a data transmission request to an uplink or a downlink. CONSTITUTION: In order for a terminal/base station RRC(110) to be transited from a standby state irrecognizable a data transmission request to an active state recognizable the data transmission request, a PDCP standby state set-up message to set the terminal/base station PCDP(120) to a state of recognizing a data transmission request from a down and up link, to the terminal/base station PDCP(Packet Data Convergence Protocol)(120). Upon receiving the PDCP standby state set-up message, the terminal/base station PDCP(120) is turned to a standby state, and transmits a PDCP standby set-up completion message to the terminal/base station RRC(110). The PDCP(120) remains in the standby state, and when it receives a data transmission request from an uplink or donwlink, the PDCP(120) transmits a PDCP transmission request recognition message to the terminal/base station RRC(110). Accordingly, the terminal/base station RRC(110) can recognize the data transmission request from the uplink or downlink. Thereafter, upon receiving the PDCP transmission request recognition message, the terminal/base station RRC(110) is transmitted from the state in which it can not recognize the data transmission request to an active state in which it can recognize the data transmission request, and transmits a PDCP re-starting set-up message to the PDCP(120) to re-start the PDCP(120) which is in the standby state.
