Abstract

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.

Claims

1-45. -45. (canceled)

46. 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;

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.

47. The method of claim 46, 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.

48. The method of claim 47, wherein a communicating method for the subsequent communication is determined by the communication parameter.

49. The method of claim 46, wherein the response condition information or the new response condition information includes a target identifier.

50. 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,

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.

51. The source device of claim 50, 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.

52. The source device of claim 51, wherein a communicating method for the subsequent communication is determined by the communication parameter.

53. The source device of claim 50, wherein the response condition information or the new response condition information includes a target identifier.

54. A method for communication with at least one target device, the method performed by a source device and comprising:

setting at least one group;

requesting a response from at least one target device corresponding to one of the at least one group, wherein a response time is set for each of the at least one group;

determining a number of the at least one target device from which a response to the request is received; and

performing or not performing a communication parameter setting operation according to the number of the at least one target device from which a response to the request is received.

55. The method of claim 54, further comprising determining a number of the at least one group.

56. The method of claim 55, wherein the number of the at least one group is determined in order to control the number of the at least one target device from which a response to the request is received.

57. The method of claim 54, further comprising comparing the number of at least one target device from which a response to the request is received to a predetermined value.

58. A source device for communication 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;

set at least one group,

transmit, via the interfacing unit, a request for a response from the at least one target device corresponding to one of the at least one group, wherein a response time is set for each of the at least one group,

determine a number of the at least target device from which a response to the request is received, and

perform or not perform a communication parameter setting operation according to the number of the at least one target device from which a response to the request is received.

59. The source device of claim 58, wherein the controller is further configured to determine a number of the at least one group.

60. The source device of claim 59, wherein the controller determines the number of the at least one group in order to control the number of the at least one target device from which a response to the request is received.

61. The source device of claim 58, wherein the controller compares the number of the at least one target device from which a response to the request is received to a predetermined value.

62. A method for transmitting a message in a mobile communication system, the method comprising:

receiving, by one or more terminals, response condition information from a network;

determining whether the one or more terminals are qualified to respond based on the received response condition information; and

responding to the network based on a result of the determination.

63. The method of claim 62, wherein the response condition information is set differently for each of the one or more terminals.

64. The method of claim 62, wherein the response condition information comprises identification information about a group to which a response message is to be transmitted or identification information about at least one terminal that belongs to a corresponding group.

65. The method of claim 62, wherein the response condition information comprises information required for determining to which group a terminal of the one or more terminals having received the response request message belongs and information about whether a specific terminal of the one or more terminals is qualified to respond.
