Description
Technical field
The present invention relates to moving communicating field, and more particularly, relate to a kind of position control method that is used for the subscriber equipment position fixing process, and the user facility positioning method that uses this position control method.
Background technology
At present, at moving communicating field, running fix and location-based service are quite attractive data services, and be also by one of the most good 3G value-added service of industry, very important for the operation income of enriching wireless data service market and increase operator.Wherein, 3G WCDMA system has merged multiple business such as voice, multimedia, and location service function wherein is quite powerful, can provide the positioning service of different brackets, different accuracy by multiple location technology, fully satisfies the demand of each side.
The WCDMA system mainly comprises two steps to the location of travelling carriage: signal measurement and calculate based on the location estimation of measuring.Wherein, signal measurement can carry out in user terminal (UE), Node B and Location Measurement Unit (LMU), measured signal is UTRA (general land wireless access) wireless transmission signal, the wireless universal navigation signal that also may comprise other, simultaneously, positioning function is not limited to the measurement of a kind of localization method or single information, can improve positioning accuracy like this; Location estimation is calculated and can be carried out in UE, also can carry out by universal mobile telecommunications system wireless access network (for example RNC-radio network controller).
The mobile positioning technique of WCDMA system mainly contains four kinds: based on cell ID positioning mode, OTDOA-IPDL positioning mode, network assistance GPS positioning mode and U-TDOA positioning mode.
Wherein, the U-TDOA positioning mode is by the time difference of different LMU according to the signal arrival that receives certain UE to be positioned transmission, estimates to calculate a kind of method of UE position.Therefore the largest benefit of this method is that it does not need present UE is made any change, and promptly UE does not need relevantly with measurement module, can save the cost of UE, makes the realization of UE location convenient yet.
When carrying out the UE location, two entities are that position measuring unit (LMU) and Serving Mobile Location Center (SMLC) will participate in the location process.Wherein, location measurement unit (LMU), can be arranged in Node B also can be independent from Node B; Equally, Serving Mobile Location Center (SMLC) can be the internal module of radio network controller, also can be independent from radio network controller, just independent service mobile position center (Stand-Alone SMLC, SAS).
The U-TDOA localization method is again in two kinds of situation: UE at CELL_FACH state and UE at the CELL_DCH state, and when UE not in this two states following time, at first will be with the UE forced branch to one of this two states.Under the CELL_DCH state, be based upon on dedicated channel (DCH) transmission channel because the RRC of UE (Radio Resource control) connects, so UE has up data to send; And under the CELL_FACH state, the RRC connection of UE is based upon on Random Access Channel (RACH) and forward access channel (FACH) transmission channel, therefore UE may not have up data to send, at this moment need radio network controller to pass through the signaling configuration UE and send upstream data, make independent service mobile position center to measure.
In addition, the U-TDOA positioning mode also is divided into the U-TDOA location that U-TDOA location that radio network controller (RNC) initiates and independent service mobile position center (SAS) are initiated, and relates to herein by the employing U-TDOA of SAS initiation UE is positioned position control method in the process.
Describe the process that under the CELL_FACH state, adopts the U-TDOA of SAS initiation to position to UE in the present standard in detail hereinafter with reference to accompanying drawing.
Fig. 1 is the structure chart when adopting the U-TDOA localization method.
With reference to Fig. 1, comprising a plurality of Location Measurement Units (LMU), be independent of NodeB, and can carry out the U-TDOA location, be used for that UE is transmitted a signal to the time that reaches and measure; Independent service mobile position center (SAS) is used to receive the signal that is sent by a plurality of Location Measurement Units, and it is carried out analytical calculation; Radio network controller (RNC) is connected with core net (CN) with Node B respectively, and receives the result of calculation from independent service mobile position center; Wherein, interface (lupc) can be arranged between independent service mobile position center and the radio network controller.
Fig. 2 is the U-TDOA localization method message flow of being initiated by SAS under the CELL_FACH state under present standard, and Fig. 3 is the flow chart of the U-TDOA location of being initiated by SAS under the CELL_FACH state under standard at present.
With reference to Fig. 2 and Fig. 3, the U-TDOA location of being initiated by SAS under the CELL_FACH state comprises following operation:
In step 1, move and serve switching center (MSC) sends position message control messages from request LE position to radio network controller (RNC); Then, in step 2, radio network controller sends the position to SAS and begins request message, and wherein, the position begins to comprise in the request message parameter in the position message control messages;
Next, in step 3, based on COS or different positioning accuracies, SAS sends to radio network controller and is used to indicate the position of U-TDOA location to activate request message, wherein, comprise the bit number of UE transmission and the interval of transmission in the position activation request message;
Then, in step 4, radio network controller activates request message in response to the position, response message is activated in the position and the U-TDOA channel information returns to SAS; Afterwards, in step 5-8, radio network controller will be carried out the process of the bit of coding in advance that makes measured UE send some in cycle regular hour.For example, radio network controller sends Radio Bearer Reconfiguration message to UE, and configuration Time Status Periodic IE wherein is 100ms, UE sends a RLC status PDU every 100ms with indication, then, UE begins to send a RLC status PDU every 100ms; When the T_rach clock in the radio network controller finishes, radio network controller sends Radio Bearer Reconfiguration message to UE, and configuration Time Status Periodic IE wherein is NA, so that UE stops status report;
In step 9, SAS utilizes the measurement result of the location measurement unit with U-TDOA ability, obtains location estimation and optional velocity estimation, and by the location Calculation applying portion position is begun response message and return to radio network controller; At last, in step 10, radio network controller sends to shift position switching center with location estimation and optional velocity estimation by the wireless access network applying portion in the report message of position.
Like this, realization is to the location of UE.
