Abstract: A system and a method for transmitting/receiving a binding update message in a communication system are provided to sense movement of an MS and set an overlay multicast session between control stations. When an ACR(Access Control Router) to which an MS(Mobile Station) 1 belongs does not receive a router advertisement message or receives the router advertisement message from ACRs, the MS senses that the MS 1 reaches to an IP(Internet Protocol) domain boundary. The ACR 1 managing the MS 1 receives data which an MS 2 transmits(335). The received data is delivered to an adjacent ACR in which the overlay multicast session is set(337,339).
Abstract translation: 提供了一种用于在通信系统中发送/接收绑定更新消息的系统和方法，以感测MS的移动并在控制站之间设置覆盖多播会话。 当MS（移动台）1所属的ACR（接入控制路由器）没有收到路由器通告消息或从ACR接收到路由器通告消息时，MS检测到MS 1到达IP（因特网协议）域 边界。 管理MS 1的ACR 1接收MS2发送的数据（335）。 所接收的数据被传送到设置了覆盖多播会话的相邻ACR（337,339）。

Abstract: A CQI transmitting device for reducing the uplink overhead and a method thereof are provided to reduce the power loss and overhead which are caused in the uplink due to unnecessary CQI transmission. A CQI transmission period change information generator(220) performs the correlation operation between the previous CQI and current CQI, and then changes the CQI transmission period according to a result value of the operation. A CQI calculation/transmission unit(214) calculates the CQI and transmits the calculated CQI to a base station by the changed transmission period.

Abstract: A method for routing a multicast packet and a system thereof are provided to reduce the signaling overhead by limiting the wireless transmission range of a control message within a multi-request zone. A source node confirms whether a multicast packet to be transmitted exists(802). The location of a destination node which will receive the multicast packet is confirmed(804). A multi-request zone including the destination node and source node is formed(808). The control message is transmitted and received to and from nodes existing in the multi-request zone(812). The multicast packet is transmitted to the destination node(816).

Abstract: A method and an apparatus for transmitting data in a communication system are provided to reduce a signaling overhead by reducing a transmission of a PHSP(Payload Header Suppression Profile) information element. A terminal confirms a generation of a traffic to be transmitted(S400), and transmits a DSA(Dynamic Service Addition)-RSQ message including a PHSP to a base station(S410). One bit PHSP information indicates byte information corresponding to a PHSS(PHS Size), a PHSM(PHS Mask), and a PHSV(PHS Valid). The terminal receives a DSA-RSP from the base station(S420), and receives a DSA-ACK message from the base station(S430).
