Embodiment approach

[0092] Pre-setting corresponding modulus parameter values ​​for different terminals, where the modulus parameter values ​​set the upload cycle of the terminal device;

[0093] When the terminal device obtains the counter value of the uploadable data, it refers to the modulus value and the offset value corresponding to the terminal device to calculate the counter value of the uploadable data. If one counting cycle of the counter contains multiple uploading cycles of the terminal, Then there will be multiple counter values ​​of uploaded data in one counting cycle of the counter.

[0094] For example, the period of the counter is "0-2999", the modulus value corresponding to a terminal device is 500, and the offset value is 7, then there will be "7", "507", "1007", "1507" four possible The counter value of the uploaded data, the terminal device can upload data when receiving any one of these four numbers.

[0095] The corresponding modulus parameter value, offset value, and time ...

specific Embodiment

[0121] According to the number of terminals in the communication network and the data upload cycle, the module parameter MOD to be allocated is obtained by dividing the terminal upload cycle by the time accuracy, and the communication terminal uses the current general counter CSC value to modulo the modulo parameter MOD to obtain the current complex value. The frame offset OFFSET finds the multiframe position that the communication terminal needs to upload in advance according to the parameters allocated by the communication system, and then uploads data in the designated time slot of the TDMA frame with the specified time division multiple access frame number within the multiframe position.

[0122] The above step of determining the relative upload time point of the communication terminal is a specific method of actively uploading the relative time point. In fact, different specific algorithms can be used for the relevant data upload time point, as long as the number of termina...

Abstract

The invention discloses a data time sequence synchronization method and system in a communication network. The method comprises the steps of sending data to a terminal through a broadcast signal; and setting continuously countable fields as clock synchronization sources of communication terminals of the communication network in the broadcast signal. According to the method provided by the invention, the uploading data is set through utilization of a counting period of a counter, so the data of any period or any format can be uploaded, and a conflict problem is effectively solved. A device employing the data time sequence synchronization method in the communication network provided by the invention also has the same advantages.

Description

technical field [0001] The present invention relates to the technical field of mobile communication networks, in particular to a data transmission method, terminal equipment, network side equipment and a system. Background technique [0002] The communication capability bottleneck of the control channel of the current trunking system has become the bottleneck of terminal access capacity, especially in applications that need to support large-capacity and high-frequency data uploading, the communication capability of the control channel has seriously affected the number of access terminals. With the growth of private network user capacity, users now have more and more demand for large-capacity data upload, and need to support active upload of conflict-free data in any period. The current technology can no longer meet user needs well. [0003] At present, there are mainly two methods for data uploading of terminals in the existing communication network: one method is that the m...
