20090131042 | APPARATUS AND METHOD FOR CONTROLLING ACCESS TO NETWORK IN WIRELESS COMMUNICATION SYSTEM - In a wireless communication system, an apparatus and method for managing an uplink communication between a network and a plurality of terminals is achieved by transmitting a response condition parameter from the network to the plurality of terminals subscribing to a multicast service. The parameter is associated with controlling the uplink communication of the plurality of terminals. The terminal then applies the response control parameter to a predetermined test and responds to the network if the terminal determines that it is qualified to respond to the network in response to a result of the predetermined test. The network evaluates whether the parameter needs to be transmitted to the plurality of terminals and whether the parameter needs to be updated based on at least part of responses received by the network. | 05-21-2009 |
20090131063 | RRC CONNECTION REQUEST METHOD AND APPARATUS FOR MOBILE COMMUNICATIONS - A method and apparatus for transmitting a single counting end message to reject the RRC connection requests of a plurality of terminals, thus minimizing the waste of radio resources and providing a quick response to those terminals that transmitted a connection request. RRC connection request messages are sent by a plurality of terminals to a network in response to an RRC connection-required message received from the network on a first channel. Each terminal monitors a second channel for an RRC connection setup message. The network establishes connections with a predetermined number of terminals by transmitting an RRC connection setup message to each terminal on the second channel and then transmits a single RRC connection-not-required message to the plurality of terminals on the first channel. Each terminal that does not receive an RRC connection setup message on the second channel after a predetermined period of time then monitors the first channel and, after receiving the RRC connection-not-required message, terminates the network connection procedure and does not re-transmit an RRC connection request message. | 05-21-2009 |
