Description
Technical field
The present invention relates to the communications field, in particular to a kind of indicating means and base station of paging carrier.
Background technology
In order to improve the message transmission rate of wireless communication system, propose multi-transceiver technology.Under the protocol infrastructure of multi-carrier wireless communications system, unified medium access control entity (MediaAccess Control, referred to as MAC) control comprise multiple channel (channel 1, channel 2 ..., channel N) physical layer (Physical layer, referred to as PHY).Wherein, each channel can have different bandwidth, and bandwidth here can be continuous or discrete frequency band.
In multi-carrier wireless communications system, for base station, carrier wave can be divided into full configuration carrier wave and partial configuration carrier wave.Wherein, full configuration carrier wave refers to the carrier wave being configured with all control channels.Control channel comprises synchronously, broadcast, multicast and clean culture control the modern channel of letter, comprises the information relevant to multi-carrier operation and other carrier waves and the channel of parameter in addition.Partial configuration carrier wave refers to the carrier wave being only included in basic control channel configuration mutual for supporting business in multi-carrier operation.
In multi-carrier wireless communications system, for terminal, carrier wave can be divided into main carrier and auxiliary carrier wave.Wherein, main carrier refers to the carrier wave for interactive service and whole PHY/MAC control information between base station (Base Station, referred to as BS) and travelling carriage (Mobile Station, referred to as MS).In addition, main carrier also for the operation of control MS, such as, network insertion.MS only has a main carrier in a community.Auxiliary carrier wave be by the specific order Sum fanction of BS be MS distribute the extra carrier for transport service.Auxiliary carrier wave also may send the control signal that some support multi-carrier operation.In one cell, MS can have one or more auxiliary carrier wave, also can not have auxiliary carrier wave.MS can obtain the partial information of auxiliary carrier wave by main carrier, such as, whether there is the position and configuration information etc. of auxiliary carrier wave, auxiliary carrier wave.Consider the service condition of main carrier and auxiliary carrier wave, main carrier is necessary for and entirely configures carrier wave, and auxiliary carrier wave can be entirely configure carrier wave or partial configuration carrier wave, depends on use and allocation models during embody rule.
At Institute of Electrical and Electric Engineers (Institute for Electrical and ElectronicEngineers, referred to as IEEE) 802.16m definition wireless communication system in, the idle pulley of MS is also provided, is used for reducing the power consumption of MS and reduces use to interface-free resources.Adjacent base station, multiple geographical position is logically divided in a paging group (paginggroup), each paging group has paging group mark (paging group ID), and a base station can belong to multiple paging group simultaneously.Like this, the paging group identification list (paging group ID list) of a paging group belonging to oneself can be preserved in each base station, the system parameters that this paging group identification list can send in superframe header and system configuration information or carry in MAC administrative messag.Idle pulley allows the switching not carrying out serving BS when moving between the different base station of MS in a paging group.After entering idle pulley, MS is assigned with a terminal iidentification, such as, temporary mark, and alternation is at paging listening intervals (PagingListening Interval) and the unavailable interval of paging (Paging Unavailable Interval).
The PGID list that base station sends on all full configuration carrier waves, and the whether paging in current paging listening intervals of the paging group representated by each PGID can be indicated by a bit.MS, after receiving above-mentioned paging group identification list, judges whether oneself is still in identical paging group.If paging group changes, then MS should carry out location update operations.If paging group does not change, and paging group belonging to it has initiated paging, and MS should monitor beep-page message in precalculated position, if carry the paging to this MS in beep-page message, MS operates accordingly in response to this paging instruction, and such as, network is reentried or location updating; If do not carry the paging action to this MS in beep-page message, MS turns back in the unavailable interval of paging.
In multi-carrier wireless communications system, when MS enters idle pulley, base station needs for its PGID specifies one entirely to configure carrier wave as paging carrier, and MS monitors the beep-page message of PGID belonging to oneself on this paging carrier.Consider that in paging group, each base station may be different for the full configuration carrier wave of paging, when MS moves in identical paging group, it is previously paging carrier that this MS specifies that current base station is used for that the full configuration carrier wave of paging may not comprise, cause MS need in current base station, carry out unnecessary carrier switch, again blind sweep or network reentry.Further, even if current base station place comprises the current paging carrier of PGID belonging to MS equally, but the full configuration carrier wave specifying other due to current base station is used for sending the beep-page message of this PGID, causes MS carrier switch unnecessary in current base station to receive corresponding beep-page message.
Except above-mentioned multi-carrier wireless communications system, the problems referred to above are present in single-carrier wireless communication system equally, and in single-carrier wireless communication system, each base station may use different single carriers for transfer of data.In this case, when MS moves in paging group, paging carrier change can occur equally and cause that MS needs are again blind sweeps that could to obtain with current base station synchronous, MS may need to carry out unnecessary network reentry even.
Cause MS to carry out the problem of unnecessary network reentry for the paging carrier uncertainty existed in current wireless communication system, not yet propose effective solution at present.

It should be noted that, the MS under idle pulley may belong to multiple paging group, and wherein, a paging group is as main paging group, and other paging groups are auxiliary paging group.MS when paging receiving message, the beep-page message of the main paging group of preferential receipt.Following examples of the present invention are described for single paging group.
Embodiment of the method
According to embodiments of the invention, provide a kind of indicating means of paging carrier.The method comprises: base station sends the information of paging carrier to MS, and wherein, paging carrier is for sending beep-page message.Base station and terminal can belong to one or more paging group.Preferably, the information of paging carrier set may further include: the corresponding relation of paging group identification list and paging carrier.
Particularly, the information of mode to MS transmission paging carrier of clean culture or broadcast is passed through in base station.Such as, under mode of unicast, base station sends the information of paging carrier to MS by De-REGistration CoMmanD message; Or base station sends information by ranging response message to terminal, wherein, when ranging response message is updating of terminal position, base station initiatively sends or sends in response to the distance measurement request message that terminal sends.Under broadcast mode, base station sends the information of paging carrier by the superframe header for carrying base station system parameters and system configuration information or medium education administrative messag to MS, wherein, paging group identification list is comprised in system parameters and system configuration information, or base station sends the information of paging carrier to terminal by beep-page message.
After this, MS receives the information from the paging carrier of base station, and according to paging carrier Resource selection paging carrier.Particularly, MS judges whether the paging group identification list of current carrier comprises paging group mark corresponding to MS, if judged result is yes, then MS continues to monitor on current paging carrier, if judged result is no, then other paging carrier that MS is switched in paging carrier list is monitored.
After this, if terminal does not get self beep-page message within the time period arranged, then terminal position upgrades or network is reentried, wherein, can by arrange timer come to the time period arranged regularly.
Further, when terminal position upgrades, base station sends to terminal and is used to indicate the beep-page message carrying out location updating, if base station does not receive the response message of terminal within the time period arranged, then base station is expanded or is switched on other carrier waves and sends beep-page message.
Further, when terminal position upgrades, current base station sends new paging information to terminal, and wherein, new paging information is used to indicate paging group mark and sends the paging carrier of beep-page message.Wherein, current base station sends new paging information by one of following message to terminal: ranging response message, the message pre-set.
Preferably, when terminal position upgrades, the paging information that base station receiving terminal reports, wherein, paging information comprises: paging group mark and paging carrier; If base station determines that the paging group mark of terminal does not change, then send ranging response message to terminal, and indicating terminal paging information does not change or partly changes wherein.It should be noted that, this preferred operations can realize based on the process of the above embodiment of the present invention, also can realize separately.
Wherein, paging carrier set can indicate one of in the following manner: mode one: the information of paging carrier comprises paging carrier set, be used to indicate all or part base station in paging group and send the paging carrier of beep-page message, wherein, paging carrier set comprises one or more carrier wave, and in paging group, base station uses the one or more carrier waves in this paging carrier set to send beep-page message; Mode two: paging carrier information comprises paging carrier set, be used to indicate the carrier wave that current base station sends beep-page message, wherein, paging carrier set comprises one or more carrier wave; Wherein, current base station uses the one or more carrier waves in this paging carrier set to send beep-page message; Mode three: the information of paging carrier comprises paging carrier set, be used to indicate current base station paging group belonging to MS and send the paging carrier of beep-page message, wherein, paging carrier set comprises one or more carrier wave, and current base station uses the one or more carrier waves in this set to send beep-page message.Below these three kinds of modes are described in detail.
Mode one: each paging group configures corresponding paging carrier set when network design, for base station each in this paging group for this paging group sends beep-page message, in this manner, the information of paging carrier comprises current base station is the paging carrier information that terminal sends beep-page message.
In order to reduce the paging carrier number of carrying beep-page message as far as possible, the embodiment of the present invention propose when network design according to the carrier information of each base station be the one or more full configuration carrier wave of all base station assigns of each paging group as paging carrier set, all base stations in this paging group can the one or more carrier waves in the paging carrier set of specifying be this paging group transmission beep-page message.Similarly, in single-carrier wireless communication system, paging group can indicate one or more carrier wave to be used for sending beep-page message.What this carrier information was mainly used to avoid MS when mobile to cause owing to not knowing carrier case on other base stations blindly to sweep or network is reentried.
Described paging carrier is integrated into when choosing to be needed to be weighed between single carrier load and variable number, when avoiding carrier set excessive, and the scanned multicarrier of MS and inefficiency; And carrier set too small time, the problem that single carrier load is too high.
Paging carrier set can inform MS in the mode of clean culture or broadcast.Distinguishingly, can send in the DREG-CMD of clean culture (De-REGistration CoMmanD) message, also can at the system parameters for carrying base station PGID list and system configuration information or other MAC administrative messags, such as, broadcast transmission in beep-page message.Further, when terminal position upgrades, base station can send in ranging response message (RNG-RSP); This RNG-RSP can be that base station initiatively sends, and also can send in response to the RNG-REQ message of terminal.
MS is when mobile, preferentially belonging to oneself paging group paging carrier set on monitor its PGID list or beep-page message, when MS detects in the PGID list in this set, all paging carriers sent the PGID all do not existed belonging to oneself, carry out location updating or network reentry operation.
Further, the carrier wave in paging carrier set according to certain principle, such as, can should select the main carrier that all MS support when selecting, and ensures that each base station in paging group has at least a carrier wave to be included in this base station.Described main carrier refers to when network design, the carrier wave of what all MS must support have some frequency and bandwidth nature.
Preferably, carrier wave in paging carrier set can arrange according to certain priority orders, can arrange priority orders such as according to coverage base station quantity and/or coverage in paging group, the carrier wave that in paging group, coverage base station number is more and/or coverage is larger can have higher priority.The paging carrier of current base station should be embodied in paging carrier set, above-mentioned information can indicate current base station to be the carrier wave that described terminal sends the paging carrier use of beep-page message, such as, can be represented by special instruction or first carrier wave being placed on paging carrier set.
Particularly, indicate during paging carrier and can be indicated by three kinds of methods.First method uses the unified physical carrier sequence number of the whole network to indicate, and in this approach, MS place preserves the carrier information of the whole network and the corresponding relation of physical carrier sequence number acquiescently, do not need the modern overhead notification MS of extra letter; Second method is by explicit carrier information, comprises center frequency point serial number information and frequency range serial number information (band class index and channelindex) etc.; The third method uses the physical carrier sequence number of base station to indicate, under the method, MS can determine its paging carrier after needing to receive the concrete multi-carrier configuration information of this base station, carries the carrier information of this base station and the corresponding relation of physical carrier sequence number in multi-carrier configuration information.Under the third method, although the physical carrier sequence number that each base station uses is different, concerning MS, the absolute information of its carrier wave is identical.
In this fashion, concrete MS paging flow process is as follows:
When MS enters idle pulley, the one or more PGIDs of base station belonging to its distribution, and the paging carrier list of each PGID beep-page message of instruction carrying.Base station in paging group can be MS transmission beep-page message in the one or more carrier waves in this paging carrier list.The list information carrier wave in paging carrier list being monitored PGID belonging to the transmission of base station is attempted in MS audit window in idle mode, if comprise the PGID belonging to oneself in the PGID list received, MS continues paging receiving message on current carrier, and carries out corresponding actions according to the instruction in beep-page message.If all do not comprise the PGID belonging to oneself in the PGID list that MS receives on all paging carriers, MS then thinks oneself not in the coverage of this PGID paging group, needs to carry out location updating or network reentry.
MS is when carrying out location updating, the paging information at new current base station place, comprise for the newly assigned PGID of MS, and paging carrier information etc. corresponding to this PGID can send to MS by the MAC message such as ranging response message (RNG-RSP) or other modes.
Base station in paging group is comprising some action instruction for certain MS transmission, such as location updating or network reentry beep-page message time, if find that within a period of time this MS does not carry out corresponding actions, when can not receive beep-page message in order to avoid causing MS due to channel condition, can the number of paging carrier be increased for PGID belonging to this MS or transform on other carrier waves as this MS sends beep-page message.
Mode two: base station decides the paging carrier at the beep-page message place of each PGID belonging to oneself in its sole discretion, and each user is given in broadcast or clean culture.In this manner, belonging to the carrier wave in the paging carrier set of current base station place and base station, paging group has corresponding relation, and wherein, current base station is that specific paging group sends beep-page message in specific carriers.
Base station is at the superframe header of bearing system parameter or system configuration information or MAC administrative messag, such as, in De-REGistration CoMmanD message (DREG-CMD) or paging broadcast message when broadcast or the PGID list belonging to clean culture oneself, carry the paging carrier of the corresponding beep-page message of each PGID at this base station place simultaneously, and each PGID can be indicated whether paged in current paging listening intervals by a bit.MS, when receiving this PGID list, if find the PGID belonging to oneself, then attempts in the listening intervals on corresponding paging carrier receiving the beep-page message issuing oneself, and operates accordingly according to instruction.
Further, when terminal position upgrades, above-mentioned paging carrier can be carried in base station in ranging response message (RNG-RSP).Wherein, described ranging response message can be that base station initiatively sends, or sends in response to the RNG-REQ message of terminal.
Wherein, indicate during paging carrier and can be indicated by following three kinds of methods: first method uses the unified physical carrier sequence number of the whole network to indicate; Second method is by explicit carrier information, comprises center frequency point serial number information and frequency range serial number information (band classindex and channel index) etc.; The third method uses the physical carrier sequence number of base station to indicate, and under the method, MS can determine its paging carrier after needing to receive the concrete multi-carrier configuration information of this base station.
When an ms moves, if successfully cannot obtain with current base station synchronous because paging carrier changes to cause and receive the PGID list of this base station, if or MS does not find the PGID belonging to oneself in the PGID list received, be then switched on other carrier waves and again attempt.Other carrier waves can once receive the carrier wave of beep-page message in history for MS, also can be new carrier wave, obtained in the carrier information that this new carrier wave can be obtained from current base station or history base station by MS.When the timer has lapsed, MS still cannot obtain synchronous with current base station, or cannot obtain the PGID belonging to oneself in the PGID list received, and MS carries out location updating or network reentry operation.
MS is when carrying out location updating, and the paging information at current base station place, comprise for the newly assigned one or more PGID of MS, and this PGID can send to MS by the MAC message such as RNG-RSP or other modes in the paging carrier information etc. that base station is corresponding.
Base station in paging group is comprising some action instruction for certain MS transmission, such as, location updating or network reentry beep-page message time, if find that within a period of time this MS does not carry out corresponding actions, when can not receive beep-page message in order to avoid causing MS due to channel condition, then can increase the number of paging carrier for PGID belonging to this MS or transform on other carrier waves as this MS sends beep-page message.
Base station clean culture when mode three: MS enters idle pulley is that MS indicates current base station place to carry the carrier wave of its beep-page message.In this manner, belonging to the carrier wave in the paging carrier set of current base station place and terminal, paging group has corresponding relation, wherein, current base station in specific carriers belonging to terminal specific paging group send beep-page message.
The PGID list belonging to oneself is broadcasted in base station on all full configuration carrier waves, and may carry a bit to indicate each PGID whether paged in current paging listening intervals.The paging carrier that each base station uses may be different, by base station self-defining.The dispersion of the broadcast paging messages of each PGID can be carried on different paging carriers by base station, and carries PGID list information on this carrier wave in the broadcast paging messages sent on each paging carrier.Such as, suppose that the PGID list belonging to base station comprises { PGID1, PGID2, PGID3, PGID4}, the full configuration carrier wave of base station comprises C1, C2}, so base station can determine to send { PGID1 on C1, upper transmission { the beep-page message of PGID3, PGID4} of PGID2}, C2.{ the list information of PGID1, PGID2} is carried in the broadcast paging messages that so base station sends on C1; { the list information of PGID3, PGID4} is carried in the broadcast paging messages that base station sends on C2.Distinguishingly, each paging carrier can send beep-page message corresponding to all PGID belonging to this base station.
When MS enters idle pulley, specify current paging carrier by De-REGistration CoMmanD message (DREG-CMD) for it by the current base station entering idle pulley.When MS moves to the coverage of other base stations, if MS cannot obtain synchronous with base station on current paging carrier, or the PGID do not comprised in the PGID list received on base station belonging to oneself, be then switched to and other carrier waves attempted synchronous and receives PGID list.If MS comprises the PGID belonging to oneself in the PGID list that base station receives, then judge the beep-page message that whether can receive the PGID comprised belonging to oneself on current carrier further.If so, then continue to monitor this carrier wave, and using the current paging carrier of this carrier wave as oneself; If not, then other full the configurations on carrier waves being switched to current base station continue to attempt paging receiving message, and before handover, MS should obtain the multi-carrier configuration information of base station, especially the full configuration carrier information of base station.If MS still cannot obtain the PGID list comprising PGID belonging to oneself during when r expires, MS should carry out location updating or network reentry operation.
MS is when carrying out location updating, and the paging information at current base station place, comprise for the newly assigned one or more PGID of MS, and this PGID can send to MS by the MAC message such as RNG-RSP or other modes in the paging carrier information etc. that base station is corresponding.
Base station in paging group is comprising some action instruction for certain MS transmission, such as, location updating or network reentry beep-page message time, if find that within a period of time this MS does not carry out corresponding actions, when can not receive beep-page message in order to avoid causing MS due to channel condition, then can increase the number of paging carrier for PGID belonging to this MS or transform on other carrier waves as this MS sends beep-page message.
In addition, under idle pulley, MS is when carrying out location updating, the PGID belonging to oneself can be reported base station, if base station judges that MS does not change paging group, its paging parameter can be indicated not make and change.Wherein, MS is used for reporting the message of PGID to be RNG-REQ message, and the indication information of base station can be carried in RNG-RSP message.
Be described in detail below in conjunction with the implementation procedure of example to the embodiment of the present invention.
With reference to figure 1, to illustrate in the present invention that in multi-carrier wireless communications system, in paging group, base station uses different paging carrier to carry out the method for paging.Fig. 1 is that in the multi-carrier wireless communications system according to the embodiment of the present invention, in paging group, base station uses different carrier to carry out the schematic diagram of paging, as shown in Figure 1, in multi-carrier wireless communications system, in paging group, the full configuration carrier set of each base station may be different, and the full configuration carrier list at A place, base station is C1, C3; The full configuration carrier list at B place, base station is C2, C3, C4; The full configuration carrier list at C place, base station is C2.
