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.
1. A method for communicating with at least one target device, the method performed by a source device and comprising:
configuring, by the source device, response condition information;
transmitting, by the source device, the configured response condition information to the at least one target device;
receiving, by the source device, at least one response, wherein the at least one response is transmitted from one or more of the at least one target device that is qualified to respond based on the response condition information and a target identifier of each of the at least one target device, wherein each of the at least one target device is configured to process the target identifier using the response condition information, and wherein a result of the processing is used to determine if the one or more of the at least one target device is qualified to respond;
determining, by the source device, whether a network condition is met based on a number of the one or more of the at least one target device from which the at least one response was transmitted;
re-configuring, by the source device, new response condition information if it is determined that the network condition is not met; and
transmitting, by the source device, the new response condition information to the at least one target device.
2. The method of claim 1 , further comprising setting a communication parameter for a subsequent communication with the at least one target device if it is determined that the network condition is met.
3. The method of claim 2 , wherein a communicating method for the subsequent communication is determined by the communication parameter.
4. The method of claim 1 , wherein the response condition information or the new response condition information includes a target identifier.
5. A source device for communicating with at least one target device, the source device comprising:
an interfacing unit configured to at least transmit data to the at least one target device or receive data from the at least one target device; and
a controller configured to:
configure response condition information,
transmit, via the interfacing unit, the configured response condition information to the at least one target device,
receive, via the interfacing unit, at least one response, wherein the at least one response is transmitted from one or more of the at least one target device that is qualified to respond based on the response condition information and a target identifier of each of the at least one target device, wherein each of the at least one target device is configured to process the target identifier using the response condition information, and wherein a result of the processing is used to determine if the one or more of the at least one target device is qualified to respond,
determine whether a network condition is met based on a number of the one or more of the at least one target device from which the at least one response was transmitted,
re-configure new response condition information if it is determined that the network condition is not met, and
transmit, via the interfacing unit, the new response condition information to the at least one target device.
6. The source device of claim 5 , wherein the controller is further configured to set a communication parameter for a subsequent communication with the at least one target device if it is determined that the network condition is met.
7. The source device of claim 6 , wherein a communicating method for the subsequent communication is determined by the communication parameter.
8. The source device of claim 5 , wherein the response condition information or the new response condition information includes a target identifier.
