Abstract: PURPOSE: A call processing method for a machine to machine communication terminal is provided to reduce power consumption by simplifying a data transmission procedure for transmitting the uplink data of a terminal. CONSTITUTION: A terminal transmits an RRC(Radio Resource Control) connection request message to a base station(803). The terminal receives an RRC connection setup message from the base station(805). The terminal receives an UL(UpLink) resource allocation message from the base station when the terminal does not transmit a service request message and a buffer state report message to the base station(806). The terminal transmits messages for processing calls.

Abstract: PURPOSE: An apparatus and a method for transmitting/receiving multimedia broadcast and multicast service(MBMS) in a wireless communication system are provided to minimize the unnecessary reception of an MBMS control channel(MCCH). CONSTITUTION: An MCCH configuration unit generates a sub-header by receiving control information related to MBMS traffic. The MCCH configuration unit generates medium access control(MAC) packet using the sub-header. The MCCH configuration unit maps the MAC packet with a logical MCCH. A scheduler(321) schedules the transmission timing and priority of the MBMS traffic channel(MTCH) and the MCCH. A transmission unit(341) maps either of the MTCH or MCCH with a physical downlink shared channel(PDSCH). The transmission unit provides identification information for transmitting the MBMS to the PDSCH a physical downlink control channel.

Abstract: A method for controlling uplink IP packet filtering in a mobile terminal in a 3GPP Evolved Packet System (EPS) is provided, including an information receiving operation of receiving IP address information allocated to user equipment, and filtering information required for delivering an uplink IP packet received from the user equipment; and a filtering operation for determining which packet data network and a bearer the IP packet is delivered to, based on the IP address information and the filtering information. In a 3GPP evolved packet system supporting a default bearer function, a packet data network to which an uplink IP packet is delivered and a bearer identifier can be efficiently determined when the user equipment simultaneously accesses one or more packet data networks and is allocated several IP addresses, resulting in effective uplink packet filtering.

Abstract: PURPOSE: An on-demand route search method in an Ad-hoc network is provided to enable all the nodes in an Ad-hoc network to rapidly optimize and search for the whole routes of the network by combining the merits of a table management method and an on-demand method. CONSTITUTION: If a route discovery message is received(S301), a mobile node defines a hop count as '1' and a transport flag as 'false'(S302). Then the mobile node judges whether 'pos', the value of an 'address_length' field, is smaller than '0'(S303). In case that 'pos' is smaller than '0', the mobile node judges whether the transport flag is defined as 'true'(S310). If 'pos' is not smaller than '0', the mobile node defines 'dest' as 'address(pos)'(S304) and judges whether the 'dest' address is its own address(S305). In case that the 'dest' address is its own address, the mobile node judges again whether the transport node is true(S310). However, if the 'dest' address is not its own address, the mobile node judges whether a route having a matched pair of£dest,next| exists in its own routing table(S306). If a route having a matched pair of£dest,next| exists, the mobile node compares the hop value of the route with the presently counted 'hop count' value(S307).
Abstract translation: 目的：提供Ad-hoc网络中的按需路由搜索方法，使Ad-hoc网络中的所有节点能够通过组合表管理方法的优点和 按需方法。 规定：如果接收到路由发现消息（S301），则移动节点将跳数定义为“1”，将传输标志定义为“假”（S302）。 然后，移动节点判断'地址长度'字段的值是否小于'0'（S303）。 在“pos”小于“0”的情况下，移动节点判断传输标志是否被定义为“真”（S310）。 如果'pos'不小于'0'，则移动节点将'dest'定义为'address（pos）'（S304），并判断'dest'地址是否是自己的地址（S305）。 在“dest”地址是其自己的地址的情况下，移动节点再次判断传输节点是否为真（S310）。 然而，如果'dest'地址不是其自己的地址，则移动节点判断具有匹配的对的路由是否为dest，next | 存在于其自己的路由表中（S306）。 如果一条路线具有匹配的一对£dest，next | 存在，移动节点将路由的跳数与当前计数的“跳数”值进行比较（S307）。
