CC MM sublayer to send "MMCC_EST_CNF" signal that the MM connection is successfully created, CC through primitive "MMCC_DATA_REQ" MM sublayer to send a "SETUP" message, state jump "Call Initiate"; MM sublayer through the access layer "SETUP" message to the network, the network receives this message, to the terminal to send "CALL PROCEEDING" message, CC Once you receive this message, you turn off the timer T303, turn the timer T310, and to SPVCALL report received "CALL PROCEEDING "message, the state will transition to a" Call Proceeding ". The after service of cell phone jammer can be implemented on line.
Network to the terminal to send "ALERTING" message is ringing, CC received the message, stop timer T310, the SPVCALL report received "ALERTING", the state and transition to the "Call Delivered"; when the terminal after the allocation of dedicated resources, MM layer through the "MMCC_SYNC_IND" primitive notification CC, CC will notify SPVCALL dedicated resources have been allocated; network to the terminal to send "CONNNECT" news, CC received the message, the network will send the "CONNECT ACKNOWLEDGE", and notify SPVCALL module, CC received a "CONNECT" message, state that to enter the "Call Active".Product Exhibition of cell phone jammer
Another way, internationally accepted protocol conformance test methods, with the base station through the real, so that the actual base station test signal terminal under the compliance testing. There are many such projects need to test the base station in accordance with the operation or scheduled way to give back to the terminal requests, more intuitive way to determine the results, will help achieve the desired results. The key is to extend the existing base station or secondary development, making the test control program can be defined by the wireless terminal conformance specification parameters, signaling processes, such as the message field to set the Node B to control, to meet the test conditions. The product exhibition of cell phone jammer will be held in the hall. Another way is to use Anritsu's system simulator, which can be used to further understand the conformance test system simulator several instances, MD8470A can simulate the behavior of TD-SCDMA network, as shown in Figure 7.9 TD-SCDMA system simulator shown in It can help R & D units in the chip or mobile application testing and protocol testing. The application rich functionality is the largest 3G mobile phone features may not be in a laboratory environment, TD-SCDMA network, in such an environment should be such as MMS, video telephony application development, we must use the system simulation.
