According to a radiation method, the emission system and a base station establish a channel used for transmitting the business data, and the business data is sent according to an emission power indicated by the base station. During the period of sending the business data to the base station, the timing advance information is sent at a preset time interval and based on the emission power. According to the present invention, a mobile station sends the timing advance information regularly according to the emission power indicated by the base station to send the business data, thereby guaranteeing that the base station receives the timing advance information, being convenient for the base station to adjust the synchronization of the business data according to the timing advance information, effectively reducing the power consumption of the mobile station, and prolonging the standby time.
Description
Technical field
The present invention relates to moving communicating field, particularly the launching technique of Timing Advance information and system.
Background technology
Because travelling carriage and base station always exist certain physical distance, when travelling carriage and base station communication, the time delay of signal transmission can be caused, if do not taken measures, the message that the travelling carriage that Shi Yanhui causes base station to receive sends on this time slot is overlapping with another message that base station receives at its next time slot, causes being correctly decoded information.Therefore, calling out in the process of carrying out, travelling carriage sends to the time delay value that the head of the measurement report of base station carries moving table measuring, base station also must supervising connections for calling arrive time and in descending SACCH (Slow Associated Control Channel slow associated control channel) message header, send instruction to travelling carriage, i.e. Timing Advance, travelling carriage sends in advance according to instruction regulation time, to reach synchronous object.
At present, it is launch according to the maximum transmission power preset that travelling carriage sends the transmitting power of Timing Advance, its objective is to be received by base station surely in order to ensure Timing Advance one.But, if the distance between travelling carriage and base station is very near, adopts maximum transmission power timing to launch described Timing Advance, be equivalent to the power supply of luxus consumption travelling carriage.Therefore, need to improve the mode of existing transmitting Timing Advance.
Summary of the invention
The object of the present invention is to provide a kind of launching technique and system of Timing Advance information, for solving the problem that timing of the prior art transmitting Timing Advance can cause travelling carriage electrical source consumption excessive.
For solving the problems of the technologies described above, embodiments of the present invention provide a kind of launching technique of Timing Advance information, comprise: set up with base station the channel being used for business data transmission, and send business datum according to the transmitting power indicated by described base station; During sending described business datum to described base station, with the time interval of presetting based on described transmitting power transmitting time advance information.
Based on above-mentioned purpose, another embodiment of the invention provides a kind of emission system of Timing Advance information, comprising: channel link block, for setting up with base station the channel being used for business data transmission, and sending business datum according to the transmitting power indicated by described base station; Timing Advance information transmitting module, for during sending described business datum to described base station, with the time interval of presetting based on described transmitting power transmitting time advance information.
Embodiment of the present invention in terms of existing technologies; the transmitting power sending business datum is indicated to carry out timed sending time advance information by travelling carriage according to base station; can guarantee that base station receives described Timing Advance information; so that base station is synchronous according to described Timing Advance information adjustment business datum; effectively can also reduce the electrical source consumption of travelling carriage, prolongs standby time.
In addition, according to the time interval of transmitting time advance information, before each transmission, judge whether to receive the transmitting power that base station provides, to judge whether travelling carriage establishes business datum with base station and be connected, before setting up business datum and connecting, launch the information set up business datum and connect according to maximum transmission power, after setting up business datum connection, the transmitting power provided according to base station carrys out emission time initial lead information.Travelling carriage can ensure the general communication with base station on the one hand, and on the other hand, once establish business datum communication, travelling carriage just need not again with maximum power transmission Timing Advance information.Reach and both ensure to be connected with base station, ensure again the power consumption object enabling Timing Advance information normal delivery.
In addition, carry out corresponding default emitting power grade according to received transmitting power, part travelling carriage carrys out transmitting business data situation with emitting power grade can be solved.
