Suddenly.
S100, caused by modem is detected because of network registry failure when Network Abnormal, the modem
Obtain the first currently used protocol stack.
In the specific implementation, modem is the abbreviation of Modulator (modulator) Yu Demodulator (demodulator).
It is transmitting terminal converts digital signals into analog signal, radiofrequency signal is converted to baseband signal by modulation, processing connects
Enter the signaling of layer (AS) and Non-Access Stratum (NAS) and carry out interface etc. with AP processor, and again will in receiving end by demodulation
Analog signal is converted to a kind of device of digital signal.Digital signal, is exactly converted into analog signal by so-called modulation；Demodulation,
Analog signal is converted into digital signal, is collectively referred to as modem, its effect is analog signal and digital signal " translation
Member ".Electronic signal is divided to two kinds, and one is " analog signals ", and one is " digital signals ".Electronic device inside mobile terminal passes
Defeated is digital signal, and what is transmitted between mobile terminal and the network equipment is analog signal.So when mobile terminal request connects
When entering mobile network, modem " translation " two different signals must be just used.Due to the electricity inside mobile terminal
Sub-device transmission is digital signal, thus have to modem come digital signal " translation " at analog signal,
It can be transmitted on network, this process is called " modulation ".When the network equipment obtains information, since the information received is simulation
Signal, thus must by modem by analog signal " translation " at digital signal, this process is " modulation /demodulation ".
In the specific implementation, mobile terminal is by sending attach request (Attach Request) message or LAU (Location
Area Update, location area updating) message originating network registration, in the registration process of mobile terminal, mobile terminal protocol stack
It is abnormal and can lead to network registry failure；Or the network coverage is weak or signal interference causes greatly mobile terminal and network communication to lose
It loses and also results in network registry failure；Or for example certain down channel transmission powers of the netconfig problem of certain network cells are matched
Set it is too low also result in random access failure or RRC (Radio Resource Control, wireless heterogeneous networks) link can not
Being successfully established leads to registration failure.Cause the abnormal cause of registration failure very much, including but not limited on address following reasons：
