摘要： PURPOSE: An apparatus for synthesizing and distributing multiple beam in a double sector structure is provided to realize the optimum use in common and obtain diversity gain without changing a terminal of a user by providing diversity to both transmitting and receiving paths. CONSTITUTION: A call estimating module(180) estimates call amount by sectors based on high frequency signals of multiple beam signals transmitted and received through a multiple beam antenna(110). Beam switching synthesizing and distributing modules(141,142) adaptively synthesize and distribute the transmitted and received multiple beam signals based on the estimated call amount for constructing variable sectors. The beam switching synthesizing and distributing modules(141,142) construct independent sectors in heterogeneous base station systems, and synthesize and distribute assigned beams of each sector alternately or successively for executing angle diversity of transmitting and receiving paths. Transmitting the high frequency signals after electric-to-optic or optic-to-electric conversion, the optical power feeding modules provide two optical transmission paths per sector on the transmitting path for differentiating signals transmitted through two optical transmission paths in a transfer rate to execute delay diversity of the transmitting path.

摘要： PURPOSE: A method for delivering a short message is provided to enable a subscriber registered in a mobile phone service to confirm a received short message in a character, voice or E-mail through a temporary mobile phone, a wired phone or the Internet. CONSTITUTION: A first MS(Mobile Station)(100) transmits a data burst message and an MS ack order to the first MSC(Mobile Switching Center)(130), and the first MSC(130) transmits a corresponding BS(Base Station) ack order to the first MS(100)(S10). The first MSC(130) requests the handling of a short message to an SMSC(Short Message Service Center)(300)(S11). The SMSC(300) transmits to the first MSC(130) a response to the short message handling and requests an HLR(Home Location Register)(400) to check the position of an MS to receive the short message(S12). The HLR(400) checks whether a phone number of the MS is substituted with another phone number. If the phone number of the MS is linked with another phone number, the HLR(400) designates a forward-to-number of the MS as a phone number of a second MS(200) for the transmission to the SMSC(300)(S13). The SMSC(300) requests routing information including a current position of the second MS(200)(S14). The HLR(400) requests a TLDN(Temporary Local Directory Number) through an interface with a second MSC(230)(S15). The second MSC(230) transmits the TLDN to the HLR(400)(S16). The HLR(400) transmits the routing information including the TLDN information to the SMSC(300)(S17). The SMSC(300) requests the second MSC(230) to transmit the short message received through the first MSC(130) to the second MS(200)(S18). A data burst message, an MS ack order and a BS ack order are transceived between the second MSC(230) and the second MS(200)(S19,S20,S21). The second MSC(230) transmits a signal notifying the completion of short message transmission to the SMSC(300). And the SMSC(300) deletes the transmitted short message(S22).
