Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to a kind of method of TDD-CDMA system same-frequency measure reporting.
Background technology
In TDD CDMA (time-division duplex) system, existing 3GPP (third generation partner program) standard provides a kind of same-frequency measure reporting mode (1G incident, promptly UE monitors and triggers measurement report when best cell changes frequently together) of Event triggered.Network side is specified the required relevant parameter of 1G incident, when UE (subscriber equipment) is in CELL_DCH (cell private channel) state and monitors when best cell changes frequently according to measuring Control Parameter, can trigger the 1G incident.And network side can be initiated handoff procedure when receiving the 1G event report.
So-called 1G event report is the behavior of UE under the CELL_DCH state, and the event report relevant parameter is subjected to network controls, and notifies UE by system information or measurement control messages.
To measure control messages is example, and the process of 1G event report is as follows:
1) UE sets up after RRC (Radio Resource control) connection, and RNC (radio network controller) sends and measures control messages (1G incident).
2) UE is according to the configuration of network, and the relevant parameter of promptly measuring in the control messages is monitored one group of common frequency measurement sub-district, and measures the pilot frequency intensity of these sub-districts.
3) UE is according to the pilot measurement result of co-frequency neighbor cell, compare with the pilot measurement value of the best cell that measured originally.
4) if following three conditions are satisfied in certain sub-district, then UE can add the information of this sub-district among the variable TRIGGERED_1G_EVENT, this variable shows the condition (may have a plurality of sub-districts to satisfy the 1G event condition simultaneously) that has those sub-districts to satisfy the 1G report, and sends the 1G measurement report.
I. the pilot tone of this sub-district is better than original best cell;
Ii. (duration is according to IE " time to trigger " (duration, this parameter belongs to measures one of Control Parameter, provides in measuring control messages or system message) for this situation certain time;
Iii. the information of this sub-district not among the variable TRIGGERED_1G_EVENT.
5) if following condition is satisfied in certain sub-district, then UE can delete the information of this sub-district from variable TRIGGERED_1G_EVENT.
I., the information that this sub-district is arranged among the variable TRIGGERED_1G_EVENT;
Ii. the pilot tone of this sub-district differs from a lagged value (this parameter also is the network side configuration) than original best cell.
In the existing protocol, there is following defective for the description of 1G incident:
1) the triggering problem of 1G incident: the description in the existing protocol (3GPP TS25.331V4e0, V590, V620) may cause the information inconsistency of network side, UE side best cell.
According to the description in the agreement, only when increasing new sub-district, variable " TRIGGERED_1G_EVENT " just can trigger the 1G incident.But have such situation: though " best cell changes ", UE can't report the 1G incident.The information inconsistency that for example, in following process, can cause network side, UE side best cell.
If a) UE is in sub-district A, along with moving of UE, the pilot tone of adjacent sub-district B, C all meets the 1G condition, so UE triggers 1G event report (this moment, adjacent sub-district B was best).
B) network side does not instruct switching for a certain reason.Such as, under the situation of Target cell inadequate resource, network side can not trigger switching; If once switching is crossed in executed before the UE, network side may and be provided with a switch protecting timer for fear of the table tennis switching, when receiving new measurement report before timer expiry, network side can not trigger switching yet.
C) UE continue to move, this moment sub-district B pilot tone very low (meeting the description of 1G incident), the information of sub-district B is deleted from variable TRIGGERED_1G_EVENT, this moment, UE still can not trigger the 1G event report.This moment, network side thought that still best cell is sub-district B.
D) UE continue to move, this moment sub-district C pilot tone become best, but because the information of sub-district C has been arranged among the variable TRIGGERED_1G_EVENT, so UE does not trigger the 1G event report.This moment, UE thought that best cell becomes sub-district C; But network side can think that best cell is still sub-district B.
As seen, according to the description of existing protocol, be not to concern one to one between " best cell changes " and the 1G incident.The 1G incident takes place, and illustrates that best cell changes; But best cell changes, and not necessarily triggers the 1G incident.Because some situation does not meet the condition described in the existing protocol.
2) the initialization problem of 1G incident correlated variables: lack initialized description in the agreement to variable TRIGGERED_1G_EVENT.
According to the description of existing protocol, UE is after receiving that 1G measures control messages, and when judging and then whether the 1G incident satisfies, its behavior has uncertainty, and the realization of each producer at present is to develop according to the understanding of oneself.Different people has different understanding, such as, initial best cell may be made as Serving cell or nullify etc.This initial setting up uncertain directly influences the deterministic process of follow-up 1G incident, thereby causes the uncontrollable of 1G incident itself.
Summary of the invention
The method that the purpose of this invention is to provide a kind of TDD-CDMA system same-frequency measure reporting, to overcome the shortcoming that may cause network side, UE side best cell information inconsistency according to existing protocol, with the timely informing network side of the detected best cell of UE, guarantee the correct switching of sub-district.

Embodiment
Core of the present invention is after UE (subscriber equipment) receives to measure control messages or system message the 1G correlated variables to be carried out initialization.During initialization 1G incident, variable TRIGGERED_1G_EVENT is set to sky or current service cell.UE as long as best cell changes and continues for some time, just triggers the 1G incident, and does not need whether to have among the judgment variable TRIGGERED_1G_EVENT information of this best cell when carrying out the judgement of 1G incident.
The present technique field personnel know, the essence of 1G incident is the mode by reporting events, with the timely informing network side of the best cell that UE saw, thereby guarantee that as far as possible the best cell that UE end, network side are understood is consistent, finally provide effective foundation for switching.Network side wishes that " the best cell information " of UE end, network side is consistent, wishes can set up relation one to one between 1G incident and " changing with the frequency best cell ".
Therefore, the present invention according to the difference of this initial value, determines the object that the 1G incident is compared when adjudicating by setting the initial value of variable TRIGGERED_1G_EVENT.
In existing 3GPP TS25.331 (V4e0) agreement on the basis of variable TRIGGERED_1G_EVENT, set up best cell variable BEST_CELL, whether adjudicate by this variable auxiliary variable TRIGGERED_1G_EVENT has best cell to change and certain time, thereby when avoiding only carrying out the judgement of 1G incident in the existing protocol, produce the inconsistent phenomenon of best cell that UE and network side are understood by variable TRIGGERED_1G_EVENT.
Perhaps by revising the data structure of variable TRIGGERED_1G_EVENT in existing 3GPP TS25.331 (V4e0) agreement, make it comprise best cell information, like this, only also can be so that 1G incident and same frequency best cell can be set up relation one to one between changing by this variable.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.

The 1G event report is the behavior of UE under the CELL_DCH state, and 1G event report relevant parameter is subjected to network controls, and notifies UE by system information or measurement control messages.
After the sub-district was set up, network side was periodically to the users broadcasting system information.System information broadcast is towards all users and periodic broadcasting, and under the situation that system configuration does not change, the system information in each cycle is identical.After UE set up the RRC connection, RNC sent and measures control messages, and this message is towards the specific user.
When UE receives measurement control messages or system information simultaneously, preferentially obtain 1G event report relevant parameter according to measuring control messages, these parameters mainly contain:
Measuring object shows that UE should measure the pilot frequency intensity of which sub-district;
The 1G event argument comprises lag parameter, the skew of sub-district individual character, duration etc.
During the initialization of 1G incident, initial value that can variable TRIGGERED_1G_EVENT is set to sky or is set to current service cell.
In order to make the 1G incident and can to set up relation one to one with between best cell changes frequently, when the data structure that defines in the data structure of variable TRIGGERED_1G_EVENT and existing 3GPP TS25.331 (V4e0) agreement is consistent, also need to set auxiliary variable, i.e. best cell information variable BEST_CELL; If revise the data structure of variable TRIGGERED_1G_EVENT, make it comprise best cell information, then do not need to set again auxiliary variable.
Step 102:UE monitors one group of common frequency measurement sub-district according to the configuration of network, and the pilot frequency intensity of these sub-districts of period measurement.
Step 103: carry out the judgement of 1G incident according to the pilot measurement result.
When carrying out the judgement of 1G incident, difference according to the initial value of the variable TRIGGERED_1G_EVENT that sets, the object that is compared during judgement is also different, can be current service cell, also can be auxiliary variable BEST_CELL or the pairing sub-district of variable TRIGGERED_1G_EVENT.Adjudicate whether best cell changes and certain time.
Step 104:, then send same-frequency measure reporting to radio network controller if court verdict is a best cell to change and continue the scheduled time.
Otherwise UE continues to measure according to the configuration cycle of network the pilot frequency intensity of co-frequency neighbor cell, the process of carrying out the judgement of 1G incident.After UE receives that indication discharges the 1G measurement event in the measurement control messages of network side or the system message, stop to measure the pilot frequency intensity of co-frequency neighbor cell.
Be example to measure control messages below, describe different execution mode of the present invention in detail:
