摘要:
An apparatus and method is provided for transmitting a signal in a communication system. Upon transition to a power saving mode, a lower layer unit sends a notification indicating the transition to the power saving mode to an upper layer unit. Upon receipt of the notification indicating the transition, the upper layer unit activates a traffic filter having a filtering condition. If upper layer traffic is generated after activating the traffic filter, the upper layer unit filters the upper layer traffic using the traffic filter, and processes the upper layer traffic according to the filtering result.

In a communication system, a terminal receives user information while an initial network entry operation is performed. The terminal transfers the received user information to an authentication server and receives an authentication information mapped to the user information required for the authentication from the authentication server. The terminal performs authentication with the authentication server using the received authentication information. Therefore, the terminal and the authentication server can securely share the authentication information, and the authentication server can easily change and manage the authentication information.

A method and apparatus is provided for transmitting data in a broadband wireless access communication system. If transmission data is generated, a data packet generator sets information corresponding to a service type of the generated data in a predetermined field of the generated data. A data packet parser parses the set information, and quality-of-service determiner determines a quality-of-service of the data set in the predetermined field according to the parsing result. A data mapper maps the data to transmission traffic according to the determined quality-of-service before transmission.

Provided is a method for setting up a route path between source and destination nodes in a mobile ad hoc network. The source node transmits a RREQ message to the destination node, which transmits a RREP message to the source node. A first intermediate node having failed to transmit the original RREP stores the original RREP, and generates and transmits a PRREQ message, to neighbor intermediate nodes. If an ID of the PRREQ and an original IP address included in the received PRREQ are identical to those of the RREQ received from the source node, a second intermediate node receiving the PRREQ generates and transmits a PRREP message corresponding to the PRREQ to the first intermediate node. If a partial route path is set up between the first and second intermediate nodes, the first intermediate node transmits the original RREP to the source node, which completes setup of the route path.

In a communication system, UE (User Equipment) concurrently provides a plurality of services based on priority. Currently available resources of the UE are confirmed when the UE is required to provide a service that is different from a plurality of services that are currently being provided. Connection of corresponding services are cancelled iteratively, starting from a service with the lowest user preference, until the currently available resources become sufficient to provide the required service if the currently available resources are not sufficient to provide the required service. The priority can be based on user preferences that are managed for a plurality of services that can be provided in the UE.

A method of controlling a User Equipment (UE) in a mobile communication system and a communication device in the UE are provided. The method including determining whether a first waiting time related to a call interruption event in a first call mode is exceeded; if the first waiting time is exceeded, transmitting a Session Initiation Protocol information (SIP INFO) message for switching the first call mode to a second call mode to an external device; and switching a call mode of the UE to the second call mode based on a response message in response to the SIP INFO message.

Scanning apparatus and scanning methods are disclosed for inspecting a surface of a semiconductor wafer. A disclosed example scanning apparatus includes a wafer stage to hold a wafer, a plurality of beam irradiators to respectively irradiate beams toward a plurality of inspection points on the surface of the wafer, a plurality of beam detectors respectively combined with the plurality of beam irradiators to form a plurality of irradiator-detector sets to detect reflected beams that are reflected from the inspection points on the surface of the wafer, a feeder unit to cause relative movement between the wafer stage and the plurality of irradiator-detector sets such that the entire surface of the wafer may be traversed by the inspection points, and a synthesizer to generate an inspection signal for the surface of the wafer by combining signals output from the plurality of beam detectors, wherein the relative movement of the wafer stage and a first one irradiator-detector sets is separate from that of the wafer stage and a second one of the irradiator-detector sets.

Disclosed is a method for setting up a route path between a source node and a destination node through route discovery in a mobile ad hoc network. The source node transmits a RREQ message to the destination node, and the destination node transmits a RREP message to the source node in response to the RREQ. A first intermediate node having failed to transmit the original RREP stores the original RREP, generates a PRREQ message, and transmits the generated PRREQ to neighbor intermediate nodes. If an ID of the PRREQ and an original IP address included in the received PRREQ are identical to an ID and an original IP address of the RREQ received from the source node, a second intermediate node receiving the PRREQ generates a PRREP message corresponding to the PRREQ and transmits the PRREP to the first intermediate node. If a partial route path is set up between the first intermediate node and the second intermediate node as the first intermediate node receives the PRREP, the first intermediate node transmits the original RREP via the partial route path. Then the source node receives the original RREP, and completes setup of the route path.

Disclosed are a system and a method for controlling wireless network access information in using a removable external modem. These relates to a case where a removable external modem among devices for a wireless access server (e.g. WiMAX) is connected with a host customer electronics (CE) device so as to be used. Particularly, in a case where the removable external modem, which has no information for accessing a specific network, e.g. operator Lock, a roaming list, a credential, operator ID, etc., when it is introduced, receives network access information through initial access, registration, and provisioning step, and is connected to other device to be used, the modem can be directly connected to a network of an existing registered network communication provider without a separate supplementary registration or a provisioning step.
