The CC allows users do not have to face the network or wireless interface error information, call control information in the correct order.        SS sub-layer is a simple state machine, which support the call independent supplementary service information is transmitted to the simple format of the information (FIE), this simple format of the information the main bearing a simple radio interface message. To complete the conversion to the format of the FIE information by the user layer of the kernel.  The 3.5 data communications services software, The data communication.
There are two ways to assess the expanded capacity of U-disks in low power cell phone jammer products.  software package is mainly used as the transparent mode of the asynchronous data transmission / non-transparent mode to provide the terminal adaptation function, which includes the relevant AT command module.  The fax package provides telecommunication services GSM No. 62 , that the fax business functions. Fax package to use data services provided in the R interface data transfer functions of the physical layer data transmission, as well as the baseband DSP and rate adaptation functions.  AT command package provides a V.24 interface to control the mobile terminal functions and GSM network services from terminal equipment  function. Testing and maintenance package is responsible for monitoring the system up and running, check the battery charge, support type certification testing, production-line calibration and machine testing functions. It is activated by the user application or L3 layer software, providing driver interface in the dedicated hardware of the low-level user.  3.7 GPRS protocol software The technology of remote control in low power cell phone jammer is the same as the one used in TVs, DVDs, and air conditions, etc.GPRS protocol software used in GPRS  the CLASS. B mobile telephone. In addition to the expansion of the existing GSM protocol software, we designed the GPRS protocol software include:
the media access control layer , Radio Link Control Habitat (AIL), LLC layer (LLC), subnet related combined layer .  3.8 WAP protocol software    WAP protocol software built on top of UDP / IP-based bearer services  and other bearer service, through the realization of a group - protocol stack, providing a WWW-based and mobile phone technology Universal Wireless Application Environment ,
 so that operators, service providers and equipment manufacturers in the wireless platform to effectively carry out the applications and services ? Wireless Datagram Protocol ? Wireless Transaction Protocol? Wireless Transport Security Layer Protocol? Wireless Session Layer Protocol ? Wireless Application Environment WSP WAP application layer between two session services provide a consistent interface, it can run WTP on the connection-oriented service or connectionless service running on the WDP. The emerging of infrared technology low power cell phone jammer products was very early. 
The WSP protocol family, WSP / B to support the the Chau browse type of application.  WTP run above the datagram service , provides a lightweight transaction-oriented protocol, simple, suitable for the client, such as mobile phones, and the completed packet stitching and delayed response function to reduce the message number.  WTLS security protocol is built on the industry standard TLS protocol, previously referred to as SSL. To achieve the authentication of the mobile terminal and the application server, Different names of low power cell phone jammer products put on varying emphasize on functions.
