WCDMA system wireless signal shielding device of automobile constructed in accordance, the characteristics that have low-power consumption, low interference, selectively masking WCDMA residential quarter and be difficult for being detected, and shield ranges is wide, and is safe, selectively the communication of shield terminal and one or more residential quarter.
As shown in Figure 7, radio signal shielding device of the present invention is mainly by finish (describing as an example of WCDMA example equally) with lower module:
Network cell pilot tone scan module: by scan for networks system descending dominant pilot, obtain the network cell quantity that this device position can receive, and the descending main scrambling code of each residential quarter use and the received power of descending dominant pilot.The cell downlink master scrambler and the dominant pilot received power information that arrive to " network cell information show and control module " and " network cell broadcast read module " output scanning, the cell downlink master scrambler dominant pilot received power and the dominant pilot timing relationship that arrive to " network cell broadcast read module " output scanning, the cell downlink dominant pilot timing relationship that arrives to " random access guiding occurs and transmitter module " output scanning.
Network cell information shows and control module: descending dominant pilot received power and network cell in certain threshold value scope in the network cell of user feedback " network cell pilot tone scan module " output, and determine to which network cell or to the terminal of any the class AC in the network cell to shield, need the network cell descending main scrambling code information of shielding to " network cell system broadcast message read module " output by the user.
Network cell system broadcast message read module: the network cell descending main scrambling code that the needs of selecting " network cell information shows and control module " to export in the cell downlink master scrambler of " network cell pilot tone scan module " output shield and the AC that needs the terminal of shielding, read descending Primary Common Control Physical Channel (the Primary Common Control Physical Channel of these residential quarters, P-CCPCH) system broadcast message of the downlink broadcast channel of carrying, the PRACH configuration information that obtains these residential quarters and need the AC of shielding, the PRACH configuration information comprises: the PRACH quantity of each residential quarter, every operable uplink scrambling code of PRACH and the up maximum transmission power of terminal, the uplink scrambling code of the PRACH channel that distributes for different AC, up access slot and signature.The cell downlink master scrambler that every PRACH that need to shield to " random access guiding generation module " output is corresponding and the up maximum transmission power of terminal and the operable uplink scrambling code of this PRACH of this cell configuration.
Random access guiding occurs and transmitter module: generates the signature that 16 WCDMA systems can the random access guiding use, the uplink scrambling code of the PRACH of the needs shielding of " network cell system broadcast message read module " output of then using respectively carries out scrambling, then the cell downlink dominant pilot timing relationship of exporting according to " network cell pilot tone scan module ", at up 15 access slots corresponding to each PRACH, use at random access signature, send 16 random access guidings with uplink scrambling code scrambling corresponding to this PRACH, each leading transmitting power is the up maximum transmission power of the terminal of this residential quarter, PRACH place permission.
If the terminal of a class or multiclass AC in the needs shielding network cell, then random access guiding occurs and transmitter module at first obtains the configuration information of PRACH corresponding to each AC of needing shielding from " network cell system broadcast message read module ", comprising: the PRACH channel that distributes for this AC, the uplink scrambling code of this PRACH channel, at up access slot and the signature of this PRACH channel for this AC distribution.Then generate the signature of all random access guidings uses that distribute for the AC that needs shielding in this PRACH channel, and use the uplink scrambling code scrambling that distributes for this PRACH.Then the cell downlink dominant pilot timing relationship of exporting according to " network cell pilot tone scan module ", in each access slot that this PRACH channel distributes for this AC, send random access guiding, each leading transmitting power is the up maximum transmission power of the terminal of this residential quarter, PRACH place permission.
This scheme is come communication between shield terminal and base station by blocking-up network system uplink random access procedure.Can select the terminal of shielding according to access category, also can to the residential quarter of shielding is selected, realize the shielding to whole residential quarter.
