An RCU (remote control unit), an antenna apparatus, an antenna electrical tilting method and an antenna system. The RCU includes a reading device and a driver. The reading device is configured to read, from a memory inside the antenna apparatus, when the antenna apparatus is communicatively connected with the RCU, antenna information of an antenna controlled by the antenna apparatus and configuration data corresponding to the antenna. The antenna information includes the antenna serial number and the antenna model of the antenna. The driver is configured to control the antenna apparatus to adjust an electrical down-tilt angle of the antenna in accordance with the configuration data.

Antenna apparatus, antenna system, and antenna electrical tilting method

Embodiments of the present invention provide an RCU (remote control unit), an antenna apparatus, an antenna electrical tilting method and an antenna system. The RCU includes a reading device and a driver. The reading device is configured to read, from a memory inside the antenna apparatus, when the antenna apparatus is communicatively connected with the RCU, antenna information of an antenna controlled by the antenna apparatus and configuration data corresponding to the antenna. The antenna information includes the antenna serial number and the antenna model of the antenna. The driver is configured to control the antenna apparatus to adjust an electrical down-tilt angle of the antenna in accordance with the configuration data.

Embodiments of the present invention provide an antenna apparatus, a system, and an adjusting method. The antenna apparatus is configured to be used in conjunction with an RCU (remote control unit, external remote control unit). The antenna apparatus includes a readable and writable memory and a motor. The readable and writable memory is configured to store configuration data of an antenna and antenna information corresponding to the configuration data, where the configuration data is used to control the RCU to drive the motor to move, so as to adjust an electrical down-tilt angle of the antenna.

The present invention discloses a phase adjustment apparatus. The phase adjustment apparatus includes at least two phase adjustment units, a switching apparatus, and a driving apparatus; where the at least two phase adjustment units are configured to modulate a phase; the driving apparatus is configured to drive the at least two phase adjustment units to move; the at least two phase adjustment units are selectively connected to the driving apparatus; and the switching apparatus is configured to select the at least two phase adjustment units, so that the driving apparatus drives, at a same moment, only one of the at least two phase adjustment units connected to the driving apparatus to move, so as to change a phase. The present invention discloses a multi-frequency antenna which applies the phase adjustment apparatus. The phase adjustment apparatus of the present invention may adjust a downtilt angle of an antenna unit.

Phase adjustment apparatus and multi-frequency antenna

A system for realizing the reception of a incoming call number by a terminal includes a CDMA network and a HRPD network providing service support for the terminal, respectively, where an MSC in the CDMA network connects with an access network of the HRPD network via interface A. A method for realizing the reception of a incoming call number by a terminal in advance includes: the MSC in the CDMA network transmitting the incoming call number of a paging to the access network of the HRPD network through interface A; the access network forwarding the incoming call number of this paging to the called terminal; the called user deciding whether to accept the incoming call based on the received incoming call number. Accordingly, the switching between HRPD and CDMA2000 1x can be avoided when the user decides not to accept the incoming call.

Method and system for realizing reception of calling number by the terminal in advance

A method for multi-path TDM data transmission includes: applying a plurality of high-speed serial lines to connect a center switch network board to a plurality of service boards; multiplexing multi-path TDM data from the center switch network board at transmitting side, and transmitting TDM data multiplexed in batch via one of the high-speed serial lines to one of the service boards; at receiving side, serial receiving the TDM data multiplexed and de-multiplexing the TDM data multiplexed to multiple TDM paths. The TDM bridge connector includes: a TDM high-speed serial transmitting adaptive circuit, and a TDM high-speed serial receiving adaptive circuit and a clock control circuit. The invention increases greatly transmission capacity and looses the requirement of clock synchronization, so the system reliability is greatly raised.
