It is the desk type cell phone jammer for the indoor use.
MOC message is GSM04 connected messages, 08 messages CM-Service Request created by the mobile station from the call set up the connection message. MTC messages are connected by GSM 04.08 Message Paging Response message, the mobile station being called the news of the established connection. LOC message GSM04.08 Location Update Request message to establish the connection message. Who, by the SCCP-UDT (messaging, message, does not belong to any connection message signs to go with UNKNOWN. For an entry Handover handoverRequest message Handover Request Acknowledge message is to be attributed to the UNKNOWN type of message. cell phone jammer is of the corresponding specifications.
Subsequent messages should be based on the type of connection in the district being served to count. Cell dependence of the statistics: When a connection is established, a cell (CELL), LAC (Location area code) and CI (cell number) element as a message is sent. Statistics of many parameters related with a specific district. The statistics message associated with a particular district must be figured out. Connection message, a cell identity (LAC / CI) is a message element BSSMAP layer Complete layer 3 information message, the SCCP CR (continuation request) message bearer. Handover control for the BSC. cell phone jammer is mainly designed for the large rooms.
New residential LAC / CI is included in the GSM08.08 HO Performed message, this message indicates successful completion of a Handover. Connection to send a message LAC and CI should be marked with 0. Means and the difficulty of statistical methods can be implemented to points, can be divided into the parameters of the message-oriented, message-oriented element parameters, process-oriented parameters. The parameters for the message refers to the extraction of parameters related news, statistics on it. For the message element of the parameter is the parameter extraction involves not only the statistical treatment of the message itself but also involves the elements of statistical processing of the message, then often have to be filtered. The over heat of cell phone jammer should be dissipated timely and correctly.
For the parameters of the process refers to the extraction of a message related to a specific process. Such as user-tracking, a CALL to establish a connection associated with this connection that the implementation process by the SCCP to complete, tracking the user not only involved in the CC layer, also related to the SCCP layer. A connection is established, the identity of its connections at both ends of the SCCP independent allocation, in order to identify the future directions of the transmission path. Some parameters can be used on the A interface to extract can be extracted on the Abis interface, such as the call rate and call blocking rate. In general, the extraction port A, to implement complex. Get more information and access equipment. Normally, when the power of cell phone jammer is bigger.
