Description
Technical field
The present invention relates to satellite field of mobile communication, and in particular to a kind of mode mobile terminal sends measurement control method.
Background technology
Existing GMR-1 Satellite Communication Systems, terminal is according to receiving system information SI1, SI2, SI2bis
In（SI System Information system informations）, neighboring BS information carry out Idle state terminal signal intensity and
Terminal location measures；The related land mobile communication system information of adjacent cells in ground is configured with these SI, so that bimodulus is whole
End carries out gravity treatment and switching between GMR-1 Satellite Communication Systems and land mobile communication system；But the adjacent area number for thering is SI to include
It is limited, it is impossible to individual land mobile communication system adjacent areas up to ten thousand in the identical area of coverage of the spot beam comprising GMR-1.Such a scene influences
Satellite, the interoperability of ground dual mode terminal, ultimately result in can not gravity treatment in time and switching, influence experience of the user to network and
Perceive.
Dual-mode terminal under the great Qu honeycombs of resident GMR-1 systems, adjacent area mode is notified using current system information, terminal without
The neighboring BS information for obtaining its present position land mobile communication system cell cellular of method promptly and accurately, so that can not be double off the net
Cell reselection and switching are carried out, influences network quality.
In GMR-1 satellite mobile communcations systems, the region of a spot beam coverage is larger, generally radius hundreds of kilometer
Region, therefore the system be great Qu cellular mobile telecommunications system；In ground moving communication system, the cellular cell area of coverage
Domain is smaller, and general radius is hundreds of meters and arrived and several kilometers, is Small Section Mode cellular mobile telecommunications system.Mode mobile terminal is in satellite
When seamless switching is carried out between mobile communcations system and ground moving communication system, switch decision needs to be based on surveying signal intensity
Amount；When the test result in satellite system shows that satellite system signal intensity is poor, it is necessary to obtain the signal intensity of ground system,
Therefore need to initiate the cell of ground system measurement, need clearly to indicate the neighboring BS information of ground system to terminal during measurement,
And the spot beam of a satellite system contains the thousands of individual adjacent areas of ground system, satellite system needs to be referred to according to terminal location
Show that mobile terminal measures to some adjacent areas of ground system；When ground system signal intensity meets different systems handoff threshold
When, satellite system instruction terminal switches over, and to ensure poor in satellite covering, the preferable scene of covered ground, terminal can be in time
Ground network is switched to, so as to ensure the continuity of business.
The content of the invention
The purpose of the present invention is to find its most suitable ground according to terminal geographic position in satellite mobile communcations system and move
Dynamic communication system adjacent area, is handed down to terminal and measures, network is can know that the land mobile communication system of terminal present position
Signal condition situation, switched in time when satellite system signal is poor.
The present invention sends measurement control method, including following step in view of the above-mentioned problems, providing a kind of mode mobile terminal
Suddenly：
S1, there is the terminal of GPS or BEI-DOU position system function, into after GMR-1 conversation states, terminal positioning module is autonomous
Position its geographical latitude and longitude information；
Its geographical latitude and longitude information is reported GMR-1 systems by S2, terminal by the measurement report message in GMR-1 agreements
Base station controller BSC；
S3, base station controller BSC send measurement control message to terminal, carry TD neighboring BS information and measurement report reports standard
Then；
S4, after satellite system base station controller BSC receives measurement report, according to switch decision criterion, whether judgement terminal
TD ground systems can be switched to from GMR-1 systems, to ensure the quality of service of call and continuity, avoid terminal because of dtr signal
Caused call drop influences the service-aware of user because speech quality is poor.
Further, the step S2 also includes：Base station controller BSC according to be stored with ground TD net cell and
Its geographical location information and terminal geographic positional information, find the TD neighboring BS information near terminal location.
Further, the step S3 also includes：It is less than thresholding when terminal measures GMR-1 signals, and ground TD believes
Number it is higher than thresholding, after delay, terminal reports GMR-1 systematic surveys to report.
Advantages of the present invention：
Between great Qu cellular systems and Small Section Mode cellular system, dual-mode terminal can carry out cell reselection in time, reduce eventually
The calling unreachable time caused by covering is too poor under Duan great areas honeycomb, improve the percent of call completed of calling；
Between great Qu cellular systems and Small Section Mode cellular system, dual-mode terminal can be based on position and obtain neighboring BS information, exhibition
Measurement is opened, when measurement amount meets switch decision condition, switching in time, ensures speech quality, prevents call drop.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.
Below with reference to figure, the present invention is further detailed explanation.
