Problems solved by technology

This leads to the inability of the traditional method to synchronize the terminal and the system well
[0010] When the terminal is synchronizing data with the system, the data uploaded by the terminal may be lost in the air due to reverse interference or poor network environment. In addition, the terminal user may switch to a new cluster system, which also needs to be transferred to System Synchronization Data
[0011] When the terminal is just turned on, switches to a new location, moves to a location after a certain distance, or after a period of time, or the system is forced to obtain terminal information, if the terminal information is inconsistent with the system information, the system will execute The function is inconsistent with the function required by the terminal information or the function to be performed by the terminal is inconsistent with the function required by the system information

[0046] Fig. 5 is a flow chart illustrating data synchronization from a terminal to a system according to the first embodiment of the present invention.

[0047] As shown in FIG. 5, the method for synchronizing data from a terminal to a system according to the first embodiment of the present invention includes the following steps:

[0048] Step A, the terminal receives a message indication of successful registration on the forward paging channel;

[0049] Step B, if the terminal detects that the currently scanned group has changed or the previous synchronization operation was not successful, then execute step C, otherwise execute step F;

[0050] Step C, the terminal sends the signaling of the data information of the terminal to the system on the reverse access channel;

[0051] Step D, whether the terminal has received a signaling from the system indicating that the terminal has successfully synchronized, if so, perform step E, otherwise perform step F;

[0052] Step E, the ...

[0055] Fig. 6 is a flow chart illustrating data synchronization from a terminal to a system according to a second embodiment of the present invention.

[0056] As shown in FIG. 6, the method for synchronizing data from a terminal to a system according to a second embodiment of the present invention includes the following steps:

[0057] Step A, the terminal receives a message indication of successful registration on the forward paging channel;

[0058] Step B, if the terminal detects that the currently scanned group has changed or the previous synchronization operation was not successful, then execute step E, otherwise execute step C;

[0059] Step C, the terminal detects whether the verification code of the system information is carried in the successful registration message, and if carried, executes step D, and if not carried, executes step H;

[0060] Step D, the terminal calculates the check code of the local data information, and detects whether the information check cod...

Abstract

The invention provides a cluster terminal direction system synchrodata method. The method comprises following steps: step S302, the terminal receives successful register message (the message refers to that the CDMA is registered successfully or the GOTAPTT is registered successfully); step S304, the terminal detects whether terminal data is synchronous according to whether the terminal data are changed or synchronous before; and step S306, a synchronization of the terminal data is carried out when the terminal is detected that the terminal data need synchronization. By adopting the technic proposal of the invention, information saved by the terminal can be consistent with that saved by the system.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for synchronizing data from a cluster terminal to a system. Background technique [0002] The digital trunking communication system is an important branch of the mobile communication system, and it is a mobile communication system applied to group dispatching and command communication. It is mainly used in the field of professional mobile communications, such as government departments, military, police, railways, water conservancy, civil aviation and steel logistics and other industries. [0003] Fig. 1 is a schematic diagram showing the structure of a digital trunking communication system. In this article, the system side or system refers to a base station or a core network, and there may be different system sides in different regions. As shown in FIG. 1 , the network of the digital trunking communication system mainly includes a trunking term...
