Below will further divide subhead to describe technical scheme of the present invention in detail.
the relation of the source of cell information and terminal motion
In GSM network, as a part for mobile management, when moving in different minizones, terminal need to carry out carrying out the replacing of Serving cell by the means such as network control of certainly advocating peace; When terminal moves in community, also there is certain rule in the variation of its cell signal.The information such as replacing number of times and the variation of each cell signal of Serving cell can reflect the motion state of terminal to a certain extent.
In one embodiment, the cell information relevant to motion state of terminal of the present invention's record includes, but not limited to Serving cell and change time, each cell signal and monitoring time.
In concrete business procedure, above cell information can be added up by monitoring following event: the cell reselection carrying out under Idle state (idle), cell reselection in switching (handover), packet switching service (Packet Switching Service) in circuit-switched service (Circuit Switching Service) process (comprising autonomous gravity treatment under heterogeneous networks pattern and the gravity treatment of network control) and measurement report of receiving under each state etc.
the selection of the cell information of multi-card multi-standby single-pass terminal
A starting point of the present invention is to judge the mobile status of terminal with main card cell information.Meanwhile, also can be according to the auxiliary mobile status that further accurately judges terminal of vice card cell information, that can determine vice card looks for net tactful.
GSM network belongs to cellular network, considers the coverage of base station, and different operators is disposed GSM community in areal have certain similitude.Therefore the cell information that main card obtains, can reflect the network condition that may face when vice card is looked for net to a certain extent.
On the other hand, in the time that main card has business, although vice card cannot be carried out the operations such as cell reselection, vice card can be carried out ionization meter to obtain vice card cell information to the existing cell signal before current business, and in the motion process of mobile terminal, constantly records the variation of this intensity.When after main card service ending, first according to the variation estimating motion state of main card cell information, when the move distance that shows this mobile terminal according to the motion state of main card estimation more in short-term, vice card cell information is considered to effective information, can be used as the foundation that follow-up vice card community is selected.If move distance is far away, in the cellular system of GSM, this value may be compared with the measured value of another community of distant positions, is not therefore effective information, and this vice card cell information possibly cannot be served as the foundation that community is selected.
estimate motion state of terminal by cell information
Obtaining after main card cell information, in the time of main card service ending, the motion state of reply mobile terminal makes a determination.The motion state of terminal comprises the following aspects: whether static, move distance, movement velocity.The rule that the present invention changes according to mobile state of terminal and main card cell information, changes the anti-mobile state of terminal that pushes away by main card cell information.In one embodiment, the present invention is can be according to erroneous judgement rule probability minimum and conform with the principle of GSM network design rule, only motion state is made to qualitative estimation.
Table 1 illustrates the estimation rule according to one embodiment of the invention.
Table 1 motion state decision rule
The description that main card cell information is changed in above rule is to judge by cell information and the certain experiences value of statistics.The average of the cell information of adding up when the present invention, by calculating retest, corresponding motion state occurs is determined.For example, repeat the longer distance test of fast mobile terminal, record its cell reselection number of times, and calculate its mean value, as threshold value or the threshold value of the longer distance of fast mobile terminal.,, in the time that Serving cell is not repeated to change number of times and reached a threshold value, to be judged as move distance long for the motion state of terminal.
Vice card cell information is mainly to comprise existing Serving cell before current business and signal strength signal intensity and the signal intensity of adjacent cell.When the move distance that shows this mobile terminal according to the motion state of main card cell information estimation more in short-term, can adopt vice card cell information further to assist the community selection of vice card.
