step 6-12: the method comprises the steps that a calling mobile terminal sends a file uploading channel establishing request to obtain file uploading channel information, meanwhile, a special wireless channel with QoS guarantee is required to be established, after MCData-PF (Multi-core data-packet) is subjected to authorization check, a 4G/5G system is requested to establish a special wireless bearer with QoS guarantee through control, the MCData-PF is informed after the 4G/5G system special wireless bearer is successfully established, and the MCData-PF finally returns a response message to the calling mobile terminal;
step 13: the calling mobile terminal uploads the MCData file in an established special wireless channel with QoS guarantee;
step 14 to step 21: after the MCData file is uploaded, the calling mobile terminal sends a file uploading channel release request to release a special wireless channel, after the MCData-PF is subjected to authorization check, the 4G/5G system is requested to release a special wireless bearer by controlling, after the 4G/5G system special wireless bearer is released, the MCData-PF is notified, and finally, the MCData-PF returns a special channel release response message to the calling mobile terminal.
Please refer to fig. 8, which shows a sequence diagram of downloading files in a qos control system of a 3GPP mission-critical data service, where the downloading of files in the system includes the following steps:
step 1: after receiving the multimedia short message of MCData file, the called mobile terminal decides to automatically establish a special wireless channel with QoS guarantee to download the MCData file;
step 2-8: a called mobile terminal sends a file downloading channel establishing request to acquire file downloading channel information, simultaneously requests to establish a special wireless channel with QoS guarantee, after MCData-PF (authorization check), a 4G/5G system is requested to establish a special wireless bearer with QoS guarantee through control, after the 4G/5G system special wireless bearer is successfully established, MCData-PF is notified, and finally response information is returned to the called mobile terminal by the MCData-PF;
and step 9: the called mobile terminal downloads MCData files in the established media channel with QoS guarantee;
step 11-17: after the MCData file is downloaded, the called mobile terminal sends a file downloading channel release request to release a special wireless channel, after the MCData-PF carries out authorization check, the 4G/5G system releases the special wireless bearer through control request, after the 4G/5G system releases the special wireless bearer, the MCData-PF is informed, and finally the MCData-PF returns a special channel release response message to the called mobile terminal.
It can be seen that, in the service quality control system of the 3GPP mission-critical data service disclosed in this embodiment, when a user sends an important and urgent file to a group or an individual through a mobile terminal, both the calling end and the called end ensure that the file is sent as soon as possible at the calling side and received as soon as possible at the called side by establishing a QoS-specific radio bearer. The problem that the speed of a key task user in an air interface is low when the key task user uploads and downloads files is solved, and the timeliness of data transmission is guaranteed. Especially in remote areas, places with poor LTE signal weak coverage and large signal congestion of people flow, the use experience of users of the emergency data service in key tasks is greatly improved.
