290 form interface.MSC280 is also structured to form interface with the BSC275 that can be couple to base station 270 via back haul link.
If any one that back haul link can be in the interface that Ganji knows is constructing, the interface includes such as E1/T1, ATM, IP,
PPP, frame relay, HDSL, ADSL or xDSL.It will be appreciated that as shown in Figure 2 system can include multiple BSC2750.
Each BS270 can service one or more subregions (or region), by multidirectional antenna or the day of sensing specific direction
Each subregion that line is covered is radially away from BS270.Or, each subregion can by for diversity reception two or more
Antenna is covered.Each BS270 may be constructed such that the multiple frequency distribution of support, and each frequency distribution has specific frequency spectrum
(for example, 1.25MHz, 5MHz etc.).
What subregion and frequency were distributed intersects can be referred to as CDMA Channel.BS270 can also be referred to as base station transceiver
System (BTS) or other equivalent terms.In this case, term " base station " can be used for broadly representing single
BSC275 and at least one BS270.Base station can also be referred to as " cellular station ".Or, each subregion of specific BS270 can be claimed
For multiple cellular stations.
As shown in Figure 2, broadcast singal is sent to broadcsting transmitter (BT) 295 mobile terminal operated in system
100.As shown in Figure 1 broadcasting reception module 111 is arranged at mobile terminal 1 00 to receive the broadcast sent by BT295
Signal.In fig. 2 it is shown that several global positioning system (GPS) satellites 300.Satellite 300 helps position multiple mobile terminals
At least one of 100.
In fig. 2, multiple satellites 300 are depicted, it is understood that be, it is possible to use any number of satellite obtains useful
Location information.As shown in Figure 1 GPS module 115 is generally configured to coordinate to obtain the positioning wanted letter with satellite 300
Breath.Substitute GPS tracking techniques or outside GPS tracking techniques, it is possible to use can track the position of mobile terminal other
Technology.In addition, at least one gps satellite 300 can optionally or additionally process satellite dmb transmission.
Used as a typical operation of wireless communication system, BS270 receives the reverse link from various mobile terminal 1s 00
Signal.Mobile terminal 1 00 generally participates in call, information receiving and transmitting and other types of communication.Each of the reception of certain base station 270 is anti-
Processed in specific BS270 to link signal.The data of acquisition are forwarded to the BSC275 of correlation.BSC provides call
Resource allocation and the mobile management function of the coordination including the soft switching process between BS270.BSC275 is also by the number for receiving
According to MSC280 is routed to, it provides the extra route service for forming interface with PSTN290.Similarly, PSTN290 with
MSC280 forms interface, and MSC and BSC275 form interface, and BSC275 correspondingly controls BS270 with by forward link signals
It is sent to mobile terminal 1 00.
Based on above-mentioned mobile terminal hardware configuration and communication system, the inventive method each embodiment is proposed.
