In a WCDMA mobile communication system, when the amount of packet traffic transmitted to or received from a UE decreases during a predetermined time in a CELL_DCH state in which a WCDMA packet data connection has been established, the UE transitions to a CELL_FACH state by a radio network controller (RNC). Thereafter, it is determined if there is no transmitted or received packet traffic during a certain time in the CELL_FACH state (which is an RRC state in which an RRC connection has been connected, and the dedicated physical channel has been released). When it is determined that there is no transmitted or received packet traffic during the certain time, the UE requests a network to release the RRC connection by utilizing a Signaling Connection Release Indication (SCRI) message. The invention enables a UE to check a packet transmission or reception flow, and to directly transmit the SCRI message to the network.

A method used by an electronic device receiving a geo-fence service, determines whether a current position of the electronic device, determined using a cellular positioning system (CPS), is located within a first distance from a central point of a geo-fence service area. In response to determining that the current position is located within the first distance, the current position is determined using a Wi-Fi positioning system (WPS) and it is further determined whether the WPS determined current position is located within a second distance from the central point of the geo-fence service area. In response to the determination the current position is located within the second distance, it is determined whether the current position calculated using a global positioning system (GPS), is located within a boundary of a geo-fence service area.

A method and apparatus for hibernation booting in a mobile terminal supporting two processors are provided. In the hibernation booting method, when power is turned on, a master processor performs hibernation booting. A slave processor performs normal booting under control of the master processor. The master processor and the slave processor determine data needing synchronizing, and perform synchronization depending on whether the data needing synchronizing have been changed.

Disclosed is a method for establishing a call connection in a wireless terminal, which can make a call connection using one line number when a call connection fails through another line number in a wireless terminal subscribing to a service in which the portable terminal uses two line numbers. The method includes receiving call release signals from a mobile switching center with respect to a call request of the wireless terminal; reattempting the call request in the wireless terminal with respect to the mobile switching center using a line number having priority, when the call release signal is received from the mobile switching center to the wireless terminal; and assigning resources from a resource pool used for another purpose so as to establish the call connection to the line number having priority when the mobile switching center receives the call request, which uses the line number having the priority, from the wireless terminal again.

A semiconductor device includes a buried isolation pattern between an active pattern on which transistors are formed and a substrate. The active pattern has adjacent sections each extending longitudinally in a first direction. A field isolation pattern is interposed between the adjacent sections of the active pattern. The buried isolation pattern has sections spaced apart from each other in the first direction under each section of the active pattern. Each section of the buried isolation pattern extends from a lower portion of the field isolation pattern in a second direction perpendicular to the first direction. At least one gate structure is disposed on each section of the active pattern, and an impurity region is located adjacent to the gate structure at the upper surface of the active pattern. The impurity region is spaced from the buried isolation pattern in a third direction perpendicular to the first and second directions. The buried isolation pattern offers a control on the body effect caused by a bias applied to the substrate.

Disclosed is a method for improving a communication success rate in a simultaneous call trial between subscribers in a mobile communication system. The method includes receiving by a second subscriber network an IAM message from a first subscriber network when a first subscriber tries a call to a second subscriber; determining by the second subscriber network whether the second subscriber has requested a termination to the first subscriber, after receiving the IAM; aborting by the second subscriber network an originating call trial of the second subscriber when the second subscriber has requested the termination; trying by the second subscriber network a page to the second subscriber after aborting the originating call trial; and setting a call between the first subscriber and the second subscriber by the first subscriber network and the second subscriber network, after succeeding in paging the second subscriber.

A method for providing a call processing service wherein a short message can be transmitted to another party using a signaling channel in cases where a traffic channel cannot be allocated (for example, in traffic congestion state). The method comprises allowing a mobile switching center to transmit a call proceeding signal to a mobile station of a calling subscriber through a radio network controller, allowing the mobile switching center and the radio network controller to carry out a resource reservation therebetween, allowing the mobile switching center to make reserved resources available and then transmit a facility signal to the mobile station, the facility signal including information about a cause of a call failure, and allowing the mobile station to receive the facility signal and then display the information about the cause of the call failure.
