Description
Technical field
The invention belongs to the communications field, speaking right control method and system in particularly a kind of trunked communication system.
Background technology
Digital Clustering is the main body of private radio communication now, it belongs to the mobile communication category together, but can collect command scheduling, phone, data, note, function such as multi-media image and OverIP is in one, and compare with the public and global mobile communication, a series of specific functions are arranged, particularly its unique feature and complexity is arranged, as the fast dispatch group calling at aspects such as scheduling and network configuration and security controls, broadcasting, clean culture, toll breakdown, intrusion, abbreviated addressing, Priority Call, hysteresis enters, environment is intercepted, control is shifted, dynamically reorganization, automatically retransmit, VPN networking etc.Its cohort user of group effectively commands, gets in touch with, scheduling and half-duplex are that main function mode is topmost feature.
CT800 is a kind of cluster common network and private network solution based on cdma network, its system configuration as shown in Figure 1, TSC in the system (Trunk Switch Center) is a Trunking Switching Center, is responsible for the traffic administration in the group system.The basic difference of CDMA trunking communication and common cdma communication is that a session can a plurality of people participate in, and each has only a user can control speaking right constantly, and therefore the management of right of speech is unusual one of important function in trunked call.
The general application scenarios of right of speech management is as described below:
Call out right of speech during the free time, system will send Floor Idle message by all MS (user terminal) in calling out, and MS receives the demonstration of message rear line can apply for right of speech.The user applies right of speech sends Floor Request message by MS to system; Authorize the application user by system behind the scope check with right of speech, and send Floor Grant to application user MS, MS indication user can talk; Other MS in current calling of system send Floor Taken message then, these MS receive after message the indication user current who hold right of speech.The user talks and finishes to discharge right of speech, sends Floor Release message by MS to system, and system regains right of speech, and all MS send Floor Idle message in calling out, and receive that the MS of Floor Idle message shows the right of speech free time to each user.
Concrete, in the prior art, behind the speech right modifying of trunked call, TSC/BSS sends right of speech message by the dedicated forward channel between each MS and BSS to MS with the mode of clean culture, notifies its current calling right of speech free time or right of speech for which user to have.Below our flow process that discharges right of speech with the talker to be that example is carried out briefly bright, flow process as shown in Figure 2:
Step 201 is for cluster user call is set up process;
Now, we suppose that user terminal MS1 has right of speech, and user terminal MS1 will discharge right of speech.
Step 202～step 203, MS1 sends FloorRelease message by the BSC/PCF1 at current place to TSC, and notice TSC discharges right of speech.
Step 204, TSC receives Floor Release message, and judges whether the active user can discharge right of speech, if can, then TSC regains right of speech, changes step 205.
Step 205～step 210, TSC sends Floor Idle message to the BSC/PCF at each MS place respectively, after each BSC/PCF receives Floor Idle message, this message is sent to MS by the dedicated forward channel that itself and each MS set up, notify the current right of speech state of each MS for idle, can apply for right of speech.
Equally, when some user terminal application rights of speech, TSC sends Floor Grant message by dedicated forward channel to the user who obtains right of speech, send FloorTaken message by dedicated forward channel to other user terminals, notify current that user terminal to obtain right of speech, their workflow is roughly the same.
In the foregoing description, TSC sends FloorGrant message, Floor Idle message and Floor Taken message and sends by dedicated forward channel, promptly all needs to send once at each MS, and this method has following shortcoming:
1, send to the identical right of speech message of each user in the calling for needs, TSC/BSC sends right of speech message by dedicated channel to each user, and size of message is big, and power hungry is many, and speech right modifying is frequent in the trunked call, has increased the weight of the system forward load;
2, each user's right of speech message is not to send simultaneously, and it is inconsistent that the user receives time of right of speech message, and certain user's right of speech state shows and lags behind.
Summary of the invention
