A host electronic device is configured to share a telephone call with a participant electronic device. The host electronic device includes a transceiver, a wireless communication module and a controller. The controller is configured to: establish a direct wireless connection with the participant electronic device; process and present incoming call data received from an outside device through a speaker and/or a display device at the host electronic device; forward the incoming call data to the participant electronic device using the direct wireless connection for presentation of the incoming call data through a speaker and/or a display device at the participant device; receive participant call data from the participant electronic device using the direct wireless connection; process and present the received participant call data through a speaker and/or display device at the host electronic device; and forward the participant call data to the outside device.

A management apparatus for managing a wireless network includes a storage storing unset communication links other than previously set communication links for a wireless communication via the wireless network among previously prepared communication links and a manager configured to divide each communication link stored in the storage into a plurality of communication links and to set the plurality of communication links in accordance with a setting request of communication links.

A method for configuring a mobile terminal and system are provided. The method includes: a mobile terminal sending local information to a server, wherein the local information comprises MSID, MDN and NAI information and expected target customer brand information predefined by the mobile terminal; the mobile terminal acquiring configuration information sent by the server, wherein the configuration information is brand information in the server, which is matched with the local information sent by the mobile terminal; and the mobile terminal acquiring a configuration parameter corresponding to the brand information according to the brand information, and completing configuration according to the configuration parameter.

Methods and devices are described for forwarding, managing, and/or detecting timing information for device-to-device discovery. Timing information may be received from a base station. A timing signal including the timing information may be transmitted. The timing signal may be transmitted during a sub-frame reserved for device-to-device discovery. Timing information for a base station may be transmitted to a user equipment (UE). Instructions to transmit a timing signal including the timing information during a sub-frame reserved for device-to-device discovery are also transmitted to the UE. Information indicating a timing of sub-frames reserved for device-to-device discovery by a neighboring base station may be received from a serving base station. A timing signal may be detected during at least one of the sub-frames reserved for device-to-device discovery. The timing signal may include timing information for the neighboring base station.

The present specification provides a method by which a user equipment (UE) simultaneously accesses a plurality of cells. The simultaneously access method can comprise the steps of: setting connections with a first cell of a frequency division duplex (FDD) scheme and a second cell of a time division duplex (TDD) scheme; and transmitting and receiving a control signal and data to and from the first cell of the FDD scheme and the second cell of the TDD scheme. Here, an uplink subframe and a downlink subframe for the first cell of the FDD scheme can be temporally divided according to the TDD scheme and provided to the UE.

A method and apparatus for using resources for a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) receives D2D resources used for transmission of D2D signals in radio resource control (RRC) idle mode, and transmits the D2D signals by using the D2D resources in the RRC idle mode. The D2D resources may be used in the RRC idle mode only, or may be used after entering the RRC connected mode. Alternatively, the UE receives D2D resources used for transmission of D2D signals in RRC connected mode, and transmits the D2D signals by using the D2D resources in the RRC idle mode.

This specification provides a method for performing a discovery procedure in a wireless communication system supporting device to device (D2D) communication. The method is performed by first user equipment and includes monitoring a discovery resource region, selecting a discovery resource for sending a discovery message in the discovery resource region, and transmitting the discovery message to second user equipment through the selected discovery resource. The discovery resource region includes a first discovery resource region and a second discovery resource region.

A server device may identify an ongoing call associated with a received handover call. The handover call may have been placed via a first network, and the ongoing call may be associated with a second network. The server device may detect that the user device has performed a handover of the ongoing call from the second network to the first network; and may process the ongoing call via the first network based on the detecting. A user device may establish a first call via a first network; detect a handover condition associated with the first network; place, based on detecting the handover condition, a second call via a second network, the second call being placed while the first call is in progress; receive an instruction to perform a handover; and send and receive, based on receiving the instruction to perform the handover, call traffic via the second call.

A first user terminal according to an embodiment comprises: at least one processor and at least one memory coupled to the processor. The processor is configured to perform processes of: determining first radio resources to be used for transmitting control information, the control information indicating location of second radio resources to be used for transmitting data by direct Device-to-Device communication; and directly transmitting the same control information repeatedly to a second user terminal in each resource block included in the first control resources.

Certain aspects of the present disclosure relate to transmitting control and data channels over multiple carriers in wireless communications. Configuration information can be obtained for a plurality of component carriers configured by one or more cells. An indication to perform parallel transmission of a control channel and a data channel with the one or more cells can be received. It can be determined whether the parallel transmission is supported over at least one component carrier of the plurality of component carriers. At least one of the control channel, the data channel, or a combination thereof, can be transmitted over the at least one component carrier based at least in part on the indication to perform the parallel transmission and based at least in part on determining whether the parallel transmission is supported over the at least one component carrier.
