An electronic device is provided. The electronic device includes a management apparatus for providing a route in a wireless communication system that includes: at least one transceiver; and at least one processor operatively connected to the at least one transceiver, wherein: at least one processor receives service information related to a service, receives cell information related to a first cell and second cells provided by a first cellular network and a second cellular network, respectively, and provides the electronic device with a service route which includes at least one second cell among the second cells and is determined on the basis of the service information and the cell information; and the service is provided by the at least one second cell.

Apparatus and method for providing route in wireless communication system

The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A communication method of a terminal in a mobile communication system according to an embodiment of the present specification comprises the steps of: acquiring cell-related information corresponding to a first communication mode; acquiring cell-related information corresponding to a second communication mode; receiving a first message through the second communication mode; and transmitting a request message corresponding to the first communication mode on the basis of the first message.

Method and device for controlling state of terminal in mobile communication system

A system is provided to manage distribution of ring back multimedia content. The system includes a data store component to store the multimedia content and to associate the multimedia content with a called system. The system includes a distribution component operable when a caller system calls the called system to provide the multimedia content as ring back to the caller system. The content may be non-ring tone content.

Multimedia caller ring distribution system and method

A system and method for providing ring back content is provided. In some embodiments, the ring back content is multimedia, audio and video, content and may be advertisements. The method includes calling a subscriber, and receiving content as ring back when calling the subscriber.

Multimedia caller ring information service

In a CDMA-based communication system, a system and method for allocating channel bandwidths and chip rates. The system and method supports asymmetric bandwidths and chip rates for the forward and reverse channels. The system and method includes a negotiation process between a mobile station and a base station to select chip rates and bandwidths for use in the forward and reverse channels.

Asymmetric channel allocation for a mobile station in a CDMA communication network

In a CDMA communication system, a method and system for controlling forward link power by a mobile station in a handover state. The method and system include transmitting different power control bits to each base station to independently control the transmission power of each base station.

Asymmetric forward power control in a CDMA communication

A decision feedback multiple symbol differential demodulator for Gaussian filtered Minimum Shift Keying (GMSK) has a performance very close to theoretical limit even under a fading channel. The demodulator implements a non-coherent, maximum likelihood (ML) search over multiple bit-time intervals. The past bit decisions are fed back to the ML decision logic. The improved performance of the demodulator is achieved by using old decisions in the ML decision logic.
