Description
Technical field
The present invention relates to moving communicating field, more specifically relate to a kind of terminal of idle mode position method for updating; In addition, the invention still further relates to a kind of method of operation of terminal of idle mode change work protocol mode.
Background technology
In the wireless communication system, the base station is the access network equipment that wireless access is provided for terminal, and the base station communicates by uplink downlink and terminal.Descending is forward direction, is meant by the direction of base station to terminal; Up promptly reverse, be meant direction by terminal to base station.A plurality of terminals can send data by up link to the base station simultaneously, also can receive data by down link from the base station simultaneously.
Global microwave access intercommunication (World Interoperability for MicrowaveAccess abbreviates WiMAX as) is a broadband wireless access metropolitan area network technology based on IEEE 802.16 agreements (Broadband Wireless Access Metropolitan AreaNetwork).Development along with technology, the IEEE802.16e that is adopted in the WiMAX communication system (hereinafter being abbreviated as 16e) agreement is evolved to IEEE 802.16m (hereinafter being abbreviated as 16m) agreement, the base station and the terminal of different agreement have appearred supporting, for example: advanced base station, advanced protocol mode base station, standard base station, advanced terminals, standard terminal.
Advanced base station (ABS) is meant can support new 16m agreement (first protocol mode), base station that again can compatible original 16e agreement (second protocol mode).The method of ABS backward compatibility 16e agreement is: the wireless messages that will eat dishes without rice or wine to transmit in time domain (Time Zone) be divided into the 16m time domain (first area, MZone) and the 16e time domain (second area, LZone); MZone is according to 16m protocol transmission wireless messages, and LZone is according to 16e protocol transmission wireless messages.
Advanced protocol mode base station (16m Only BS) is meant the base station that can only support new 16m agreement.
(YBS) is meant the base station that can only support original 16e agreement in the standard base station.
Advanced terminals (AMS) is meant can support new 16m agreement, can support the terminal of original 16e agreement again.
(YMS) is meant the terminal that can only support original 16e agreement in the standard terminal.
The 16e protocol specification idle pulley (Idle Mode), the purpose of idle pulley be to reduce terminal energy consumption, reduce taking to the serving BS interface-free resources.Behind the terminal access idle mode, only in the discrete time interval, periodically receive the downlink broadcast data (comprising: beep-page message and multicast, broadcast service data etc.) that the base station sends, and in passing through the moving process of a plurality of base stations, do not need to switch and network reentry operation.
According to prior art, idle mode terminals need upgrade executing location renewal operation under the satisfied situation of trigger condition (comprising: paging group, timer, outage, MBS) in any one position.The position is upgraded and can be divided into safe position renewal and the renewal of non-safe position.If terminal can be shared effective safe context with preferred base station (preferred BS), then carry out the position of safety and upgrade; If terminal can not be shared the current effective safe context with preferred base station, then to carry out network and reentry, just non-safe position is upgraded.
The 16m agreement has been inherited idle pulley, although the idle pulley in the 16m agreement is realizing that the 16e agreement with traditional is identical on the principle, there are great changes in concrete implementation method.Therefore, in the wireless communication system of forming by ABS and YBS, under the idle pulley, there is the problem of the traditional 16e agreement of 16m protocol-compliant.
For example, AMS follows the idle pulley of 16e protocol specification under the LZone of ABS.When this AMS moves to following time of MZone, because the implementation method of two kinds of idle pulleys under 16m agreement and the 16e agreement is different, the AMS that will cause entering the idle pulley of following the 16e agreement can't operate as normal under the MZone of ABS.Obviously, for a reliable wireless communication system, be not allow to occur terminal to be under the wireless communication system, the but situation that can't communicate with terminal.
Same, the base station of different time zone of same base (LZone or MZone) and different operating protocol mode (16e base station or 16m base station), all only broadcast the base station of the identical work protocol mode in its adjacent area and/or the system information of time zone, for example: the broadcast of LZone (such as neighboring broadcast messages) is only broadcasted the system information of the LZone of adjacent area YBS and other ABS of adjacent area.Therefore, when the gravity treatment of sub-district, the idle mode terminals of certain work protocol mode be can't be directly from the base station at its place and/or time zone obtain other work protocol mode base stations and/or the time zone system information, for example: the idle mode terminals that is in the LZone of ABS just can't directly obtain the system information of the MZone of this ABS from the broadcast of LZone.At this moment, if this terminal need move to the base station and/or the time zone of other work protocol modes, just have only and blindly sweep relevant base station and/or time zone obtains required system information.Yet, blindly sweep that the mode of obtaining system information is consuming time for a long time, efficient is low, increased the time that non-occupied terminal is changed greatly between the different operating protocol mode.

In order to solve idle mode terminals compatibility issue when mobile between the base station of supporting the different operating protocol mode and/or time zone, the present invention proposes a kind of new idle pulley location updating method (trigger mechanism), that is: idle mode terminals perhaps (comprising: move the LZone of adjacent area YBS, adjacent area ABS) at the MZone of ABS and the LZone of neighbor base station between the LZone and MZone of ABS.When the work protocol mode of terminal need change, triggering terminal is upgraded non-safe position under new work protocol mode immediately, just carries out new work protocol mode network down and reentries and operate.The implementation method of concrete scene is as follows:
1.ABS LZone down or the idle mode terminals under the YBS, can be synchronized to MZone current or other ABS of adjacent area at the unavailable time slot scanning of paging; Terminal is in the time zone or the base station of scanning preface information (for example: preamble and A-preamble) back identification different agreement pattern; Subsequently, terminal can be from broadcast (for example: SFH) know concrete MAC version information (MAC version);
Further, if decision moves to corresponding M Zone, terminal behind MZone, in the distance measurement request message that corresponding MZone sends the code word of carrying 0b00, is carried out the network reentry of MZone in scan-synchronized subsequently according to the indication of base station;
2. move to the LZone of adjacent area YBS or other ABS of adjacent area from the MZone of ABS when idle mode terminals; The time zone or the base station of terminal identification different agreement pattern behind scanning preamble; Subsequently, terminal can be from system broadcast message (for example: obtain concrete MAC version information (MAC version) DCD/UCD);
Further, terminal learns that the base station is only to support the YBS of 16e agreement or the LZone of ABS, if selected corresponding YBS or LZone are as preferred base station (preferredBS), terminal is after scan-synchronized arrives YBS or corresponding LZone, the distance measurement request message of the code word of 0b00 is carried in transmission, carries out the network reentry of YBS or corresponding LZone subsequently according to the indication of base station.
Enumerate two embodiment at this.
First embodiment:
The AMS of idle pulley works in the 16e pattern, and (AMS moves to ABS from adjacent area YBS, and rests under the LZone of ABS; Also may be directly to enter idle pulley) at LZone or the YBS of ABS.At the unavailable time slot of paging, AMS learns by scanning and exists base station or the current base station of supporting the 16m pattern to have the time zone (MZone) of supporting the 16m pattern on every side.In order in time to obtain the better services quality that higher protocol version brings, the selected base station of supporting the 16m pattern of AMS is as preferred base station.Subsequently, the protocol mode of will working changes the 16m pattern into by the 16e pattern, base station or time zone in the 16m pattern send AAI RNG-REQ, this message indicates AMS to want to carry out network reentry operation under the 16m pattern by the code word of carrying 0b00, after this, AMS finishes network and reentries, and works according to the 16m pattern.
Second embodiment:
The AMS of idle pulley works in 16m pattern (AMS directly enters idle pulley at the MZone of ABS or 16m Only BS).The AMS position is moved, and by at the unavailable time slot of paging, scans and learns that current base station is to support the base station of 16e pattern.Subsequently, the AMS protocol mode of will working changes the 16e pattern into by the 16m pattern, and send RNG-REQ to the base station, place according to the 16e pattern, this message is carried the code word of 0b00 and is indicated AMS to want to carry out network reentry operation under the 16e pattern, after this, AMS is accomplished to the network of base station, place and reentries, and works according to the 16e pattern.
In addition, the invention allows for a kind of method of operation of terminal of idle mode change work protocol mode.Summary of the invention has comprised four kinds of scenes and multiple different method of operation.Specifically describe below.
Scene one (after idle pulley AMS moved to ABS and rest on LZone from YBS, perhaps AMS was after LZone enters idle pulley, and decision moves to MZone).
Major programme (twice position upgraded: ABS LZone send have the MZone system information message to AMS, described message can be that ABS initiatively sends, perhaps the request according to AMS sends;
Idle mode terminals carries out the position at MZone and upgrades according to the system information that LZone obtains MZone)
Further, under the LZone of ABS, be in the AMS of idle pulley,, can obtain the system information (carrier frequency information, targeting sequencing information and the other system information that comprise MZone) of all or part of MZone in advance at LZone if decision moves to the MZone of this ABS.Concrete grammar comprises: AMS sends a request message to ABS at LZone, and it is the regional conversion operations that will do under the idle pulley that this request message need be indicated the purpose of AMS this moment; This indication can be represented the purpose of AMS by increase a field newly in request message;
In case receive this request message, ABS can be according to the request purpose of AMS, and the message that has the MZone system information in the LZone response is given AMS;
According to the assistance of the response message of receiving, AMS is synchronized to MZone; More newly arrive in the MZone executing location subsequently and obtain the paging parameters of MZone;
In position updating process, AMS sends a request message to ABS at MZone, and the purpose that message is carried is designated as the position and upgrades;
Receive the request message of AMS, ABS sends at MZone immediately and carries the response message of new paging parameters to AMS;
Subsequently, AMS can operate according to the new paging parameters of receiving, paging receiving message on MZone;
Replacement scheme (position is upgraded: ABS LZone send have MZone system information and paging parameters message to AMS, described message can be that ABS initiatively sends, perhaps the request according to AMS sends.
Idle mode terminals is synchronized to MZone, in MZone paging receiving message according to system information and paging parameters that LZone obtains MZone)
Further, under the LZone of ABS, be in the AMS of idle pulley, if decision moves to the MZone of this ABS;
AMS sends a request message to ABS at LZone, and it is the regional conversion operations that will do under the idle pulley that this request message need be indicated the purpose of AMS this moment, and the information of request MZone; This indication can be represented the purpose of AMS by increase a field newly in request message;
ABS has the message of MZone information to AMS in the LZone response immediately at the request message that LZone receives AMS;
But, being different from major programme 1, ABS issues AMS in the middle of also can be simultaneously the paging parameters of MZone being carried at response message;
Receive this response message, AMS is synchronized to MZone, operates according to new paging parameters, subsequently paging receiving message on MZone;
Scene two (rest on the idle pulley AMS of the MZone of ABS, move to LZone)
Under the MZone of ABS, be in the AMS of idle pulley, move to the LZone of this ABS if desired, can obtain the information of all or part of LZone in advance at MZone.Its concrete grammar comprises:
1. major programme:
Mode a
ABS utilizes beep-page message indication AMS to carry out range operation at MZone; This indication can be represented by corresponding field is set in the beep-page message;
In the ranging process, AMS sends the request message that has " conversion of idle pulley lower area " indication at MZone and gives ABS; ABS gives AMS in the message that the MZone response has the time offset between MZone and the LZone;
According to the assistance of the response message of receiving, AMS is synchronized to LZone; Executing location is more newly arrived and is obtained the paging parameters of LZone subsequently; And operate paging receiving message on LZone according to new paging parameters.
Mode b
Select as another kind, ABS can be directly sends not requested message to AMS in the paging availability interval of AMS on MZone, and message is directly carried the system information of LZone;
Because the information that the message of receiving is carried LZone, AMS knows that it is transformed into LZone to ABS in indication; According to the assistance of the message of receiving, AMS is synchronized to LZone; Executing location is more newly arrived and is obtained the paging parameters of LZone subsequently; And operate paging receiving message on LZone according to new paging parameters.
2. replacement scheme
Similar with scene one described replacement scheme, no matter adopt mode a or b in the middle of the scene two, as an alternative, ABS can directly carry the paging parameters of LZone in the middle of MZone gives the message of AMS; In case after receiving that this message is obtained relevant parameter, AMS directly is synchronized to LZone, operate according to new paging parameters, subsequently paging receiving message on LZone;
Scene three (rest on the idle pulley AMS of the MZone of ABS, move to adjacent area YBS)
Mode a
Under the MZone of ABS, be in the AMS of idle pulley, move to adjacent area YBS if desired, can obtain the system information of all or part of adjacent area YBS in advance.
ABS sends message at MZone and indicates the time offset (time offset) between MZone and the LZone to (optimal way is broadcasting) AMS; AMS receives message, thereby obtains the system information of adjacent area YBS after receiving this message on corresponding LZone.According to the information that obtains, AMS can select corresponding YBS as first-selected BS (preferred BS) in cell reselection process; If move to this YBS, the paging parameters under this YBS, paging receiving message under YBS are obtained in AMS executing location renewal immediately operation.
Mode b
Under the MZone of ABS, be in the AMS of idle pulley, ABS can directly send comprise adjacent area YBS the neighbor base station system information to AMS; The ABS here mixes ABS (having LZone and MZone), also can be the ABS (only having MZone) of 16m only.
According to the neighbor base station information that obtains, AMS can select corresponding YBS as first-selected BS (preferred BS) in cell reselection process; If move to this YBS, the paging parameters under this YBS, paging receiving message under YBS are obtained in AMS executing location renewal immediately operation.
Scene four (idle mode terminals moves to the ABS of 16m only or the MZone of ABS from YBS)
The AMS of idle pulley is under the YBS, and YBS can send the message that (optimal way for broadcasting) comprise the MZone system information of adjacent area 16m only ABS or ABS and give AMS;
According to the information that obtains, AMS can be in cell reselection process, and the MZone that selects corresponding 16m only ABS or ABS is as first-selected BS (preferred BS); If move to the MZone of this 16m only ABS or ABS, new paging parameters, paging receiving message under the MZone of this 16m only ABS or ABS are obtained in AMS executing location renewal immediately operation.
Further set forth the present invention in the mode of example below.
