Description
Technical field
The present invention relates to communication technical field, particularly a kind of inter-system measuring method and terminal, circuit commutative field backing method and system.
Background technology
In the prior art, in order to maximize investment return, satisfy the customer service continuity, operator can dispose a plurality of Radio Access Networks simultaneously, move second generation mobile communication system (2G simultaneously as operator, 2ndGeneration Mobile Communications System), 3-G (Generation Three mobile communication system) (3G, 3rdGeneration Mobile Communications System) and Long Term Evolution (LTE, Long TermEvolution) system, in order to keep the continuity of speech business between LTE system and the 2G/3G system, prior art has proposed a kind of circuit commutative field rollback (CS Fallback, Circuit Switched Fallback) method, when terminal resides in the LTE system, if terminal is initiated audio call, then this audio call is return back to the CS territory of 2G/3G system, provide speech business by the CS territory of 2G/3G system for this terminal.
If audio call will be return back to the CS territory of 2G/3G system, then need to carry out isosystem measurement, namely when terminal resides in the LTE system, if need come carry voice traffic by the CS territory of 2G/3G system, be that terminal need be implemented CS Fallback, then the base station indicating terminal of LTE system carries out isosystem measurement, after terminal receives indication, in the 2G/3G system, carry out isosystem measurement, thereby selection, the channel information of realizing the residential quarter are mutual etc., measurement report are sent in the LTE system then and provide serving base station for this terminal.
As shown in Figure 1, carry out the method flow diagram of CS Fallback for terminal in the prior art, its concrete processing procedure is as follows:
Step 11, if terminal resides in the LTE system, and terminal need carry out audio call, then terminal by in the LTE system for self provides serving base station, send the expansion service request to Mobility Management Entity (MME, MobilityManagement Entity);
Step 12 after above-mentioned MME receives the expansion service request, sends S1-application protocol (AP, the Application Protocol) message that comprises the CSFallback sign to above-mentioned base station, carries out CS Fallback mechanism in order to notify this base station at this terminal;
Step 13, base station need to determine whether this terminal to carry out isosystem measurement after receiving above-mentioned S1-AP message;
Step 14 if the base station is determined terminal and need be carried out isosystem measurement, then indicates this terminal to carry out isosystem measurement;
Step 15, terminal is carried out isosystem measurement;
Step 16, terminal sends to this base station with measurement report, carries cell ID that measure, the Target cell when switching to the 2G/3G system in this measurement report;
Step 17, after this base station receives measurement report, the Target cell of the cell ID correspondence of carrying in the measurement report with this terminal transmission, the audio call of this terminal is just handled by the CS territory of 2G/3G system so.
By above-mentioned processing procedure as can be known, when terminal is carried out CS Fallback, terminal may need to carry out isosystem measurement, but isosystem measurement need expend the long time, when for example terminal is initiated audio call, return back to the 2G system from the LTE system and need 5 seconds, return back to the 3G system from the LTE system and need 4 seconds, and isosystem measurement wherein just need expend the general time more than 1.4 seconds, this shows, isosystem measurement has taken the more time of CS Fallback, and this just greatly reduces the treatment effeciency of CS Fallback.
Summary of the invention
