Provided is a purifying apparatus, which includes ultraviolet lamps and an ozone lamp having different wavelengths from one another and disposed in tubes to remove bacteria, VOC, bad odors in water or air, and these tubes are arranged in a serial or parallel way. Folds are formed at inner ends of the spiral photocatalytic sheets which are in contact with the lamps and the respective lamps are inserted into to increase the contact area with air or water and the one with the lamp, thereby preventing the lamp from being damaged. The purifying apparatus includes: an outer case having an inlet and an outlet; a spiral photocatalytic sheet to be inserted into the outer case; a UV lamp to be inserted into the spiral photocatalytic sheet, wherein folds are disposed at an inner side of the spiral photocatalytic sheet where a space for inserting the UV lamp is formed.

Provided are a physical downlink control channel (PDCCH)-based scheduling method and apparatus suitable for use by a base station in a long-term evolution (LTE) system. The scheduling method includes: determining an aggregation level of a common search space of a PDCCH by considering channel quality of a plurality of user equipments (UEs); identifying the number of PDCCH candidates and the number of messages, which require allocation of the common search space, based on the determined aggregation level and selecting messages by a smaller number of the number of messages and the number of PDCCH candidates; and allocating PDCCH resources and physical downlink shared channel (PDSCH) resources for the selected messages. In a situation where the PDCCH resources are shared by downlink scheduling information and uplink scheduling information of different UEs, the PDCCH resource-based scheduling method can be used by the base station to efficiently utilize the PDCCH resources.

A method of changing codebook configuration stored in user equipment (UE) by a base station includes deciding a PMI to recommend for use in each frequency band available to the UE which is being provided with service from the base station, deciding a PMI to restrict use of for each frequency band available to the UE which is being provided with service from the base station, transmitting PMI coordination information including recommendation coordination type information and PMI information in which the PMI to recommend for use is designated for each corresponding frequency band to the UE, and transmitting PMI coordination information including restriction coordination type information and PMI information in which the PMI to restrict use of is designated for each corresponding frequency band to the UE.

Provided is a method of transmitting data in at least one machine type communication (MTC) device belonging to an MTC group identified by a unique identity according to application features. The method includes setting, by at least one MTC device belonging to the MTC group, unique transmission latency; waiting, by the MTC device, for the set transmission latency and then receiving information on uplink resources allocated to each MTC group identity from a base station; and transmitting, by the MTC device, uplink data using the allocated uplink resources.

A method of multiplexing data of a terminal is provided. The method comprises receiving uplink resource allocation information about a service specific identifier for a specific service and information for the specific service comprising a radio bearer (RB) list to be transmitted through resources that are allocated according to the uplink resource allocation information from a base station and multiplexing data of the RB list to the allocated resources.

A method of assigning a resource of a united system in which a plurality of single systems are complexly operated includes: determining a cost function using standard network state information commonly used within the united system; and assigning a resource based on the cost function. Therefore, a state of each system and user requirements can be fully reflected and a resource can be efficiently managed within a united system in which several systems are complexly operated.

The SIP-based multimedia communication system for providing mobility using lifelong numbers provides mobility through SIP network service domains and a global domain. The SIP network service domain comprises a user agent and an SIP network server. The user agent transmits request/response messages between users to set up, correct, and cancel calls, and when contact information of the user agent is registered and registration of the contact information is cancelled, requests to be informed of state changes in registration information. The SIP network server performs message routing between user agents and informs the contact information of the user agents during message routing. The global domain manages the SIP network service domains and allocates global SIP identifiers, that is, lifelong numbers to users to provide user-centered mobility.

A context information management system provides service mobility that allows user to maintain service even while moving the service environment. That is, when user service environment movement is sensed, user service provided in previous service environment is consecutively provided to the user in the new service environment using the service context information of user service provided in the previous service environment. In such a manner, the service user may continuously use a same service that used in the previous service environment although the user moves to other service environments without a service terminal.
摘要:
A method for supporting session mobility, more particularly, a method for supporting session mobility that can move various sessions between two or more devices by using session initiation protocol (SIP). Various sessions can be simultaneously moved by utilizing a SIP PUBLISH message. Accordingly, a user can utilize various services as they are regardless of changing of service receiving device while the user utilizes various services. Also, the session mobility can be effectively supported whether the target of the session movement is known or not.

Disclosed is a method for blocking SMS spam messages in an SMS server or a mobile terminal. If the server receives an SMS message to be transmitted to a subscriber from a base station, it is determined if a spam blocking option is set. If the spam blocking option is set, a spam-blocking database is accessed to search for a phone number corresponding to the received message, so as to check whether the number is registered in the database. If the SMS message phone number is registered in the spam-blocking database, the procedure is ended without SMS message-processing for the message, so that spam messages are blocked from being transferred to the subscriber. If the terminal receives an SMS message, a spam-blocking database in the mobile terminal is accessed to determine if the received message is an SMS spam message. If the received message is an SMS spam message, the terminal is controlled not to notify receipt of the message.
