Description
Technical field
The present invention relates in wireless communication system, receive the method for disaster warning message (or any warning message).More specifically, the terminal (UE) of attempting to receive warning message receives Broadcast Control Channel (BCCH) in respective cell, obtain system information by BCCH, and receive warning message by downlink channel according to the schedule information that is included in the system information about warning message.
Background technology
Fig. 1 is that prior art and the present invention are applied to said system as the exemplary network structure of the evolved universal mobile communication system (E-UMTS) of mobile communication system.The E-UMTS system is the system from the UMTS system evolved, and currently carries out its standardization effort by the 3GPP normal structure.The E-UMTS system also is called as Long Term Evolution (LTE) system.
The E-UMTS network can be divided into evolved universal terrestrial wireless access network (E-UTRAN) and core net (CN) roughly.The IAD (AG) that E-UTRAN generally includes terminal (that is subscriber equipment (UE)), base station (that is eNode B) and an end that is positioned at the E-UMTS network and is connected with one or more external networks.AG can be divided into the part that is used for the process user business and be used for the part of processing controls business.At this, the AG that is used to handle the AG of new customer service and be used for the processing controls business can communicate each other by using new interface.An eNode B can have one or more sub-districts.Can between eNode B, be used to send customer service or the professional interface of control.CN can comprise AG, be used for the node etc. of user's registration of other UE.Interface can be used for E-UTRAN and CN are distinguished from each other.
Three lower levels based on known OSI(Open Systems Interconnection) master pattern in communication system can be divided into the Radio interface protocols layer between terminal and the network ground floor (L1), the second layer (L2) and the 3rd layer (L3).The physical layer that belongs to ground floor uses physical channel that information transfer service is provided.Be positioned at the 3rd layer Radio Resource control (RRC) the layer control terminal of lowermost portion and the Radio Resource between the network.For this reason, rrc layer allows exchange RRC message between terminal and network.
Fig. 2 illustrates based on the terminal of 3GPP Radio Access Network standard and the Radio interface protocols framework between the E-UTRAN.Radio interface protocols among Fig. 2 has the level course that comprises physical layer, data link layer and network layer and has the vertical plane that comprises the chain of command that is used to send user's face of customer service and is used to transmit control signal.Based on three lower levels of known OSI(Open Systems Interconnection) master pattern in communication system, the protocol layer among Fig. 2 can be divided into ground floor (L1), the second layer (L2) and the 3rd layer (L3).Below, with each layer in the wireless protocols framework of describing among Fig. 2.
Ground floor as physical layer uses physical channel to provide information transfer service to the upper strata.Physical layer is connected thereto layer by transmission channel, is called as medium access control (MAC) layer.MAC layer and physical layer are by the transmission channel swap data.Data are transmitted by physical channel in (that is, between transmitter side physical layer and receiver side physical layer) between the different physical layers.Based on OFDM (OFDM) technology physical channel is modulated, and physical channel service time and frequency are as Radio Resource.
The MAC layer that is positioned at the second layer provides service by logic channel to the upper strata, is called as Radio Link control (RLC) layer.The reliable transfer of data of rlc layer support of the second layer.The function of rlc layer can be embodied as the functional block of MAC layer.In this case, can there be rlc layer.Packet data convergence protocol (PDCP) layer at the second layer of radio protocol user plane is used to use narrow relatively bandwidth to send the IP grouping effectively on wave point, such as IPv4 or IPv6.For this reason, the PDCP layer reduces larger-size and comprises the size of unnecessary control information IP packet header,, carries out the function that is called as header-compressed that is.
Only be positioned at Radio Resource control (RRC) layer of the 3rd layer lowermost portion in the chain of command definition.Logic channel, transmission channel and physical channel that rrc layer control is relevant with foundation, reconstruction and releasing wireless loading (RB).At this, RB represents the service that is used for carrying out transfer of data between terminal and E-UTRAN that the second layer provides.Be connected if set up RRC between the rrc layer of the rrc layer of terminal and wireless network, then terminal is in the pattern that RRC connects.Otherwise terminal is in the RRC idle pulley.
Non-access aspect (NAS) layer that is positioned at the top of rrc layer is carried out the function such as session management, mobile management etc.
The bandwidth of cell of formation eNB is set among 1.25MHz, 2.5MHz, 5MHz, 10MHz, the 20MHz etc., so that down link or ul transmissions service to be provided to a plurality of terminals.At this, different sub-districts can be set to the bandwidth that provides different.
Be used for data can be comprised the broadcast channel (BCH) that is used for transmitting system information, the paging channel (PCH) that is used to send beep-page message and the downlink sharied signal channel (SCH) that is used to send other customer service or control messages from the downlink transmission channel that network sends to terminal.Can send business or the control messages that the down link point-to-multipoint is served (multicast or broadcast service) by down link SCH or by independent down link Multicast Channel (MCH).In addition, be used for data can be comprised Random Access Channel (RACH) that is used to send initial control messages and the uplink shared channel (SCH) that is used to send customer service or control messages from the uplink transmission channels that terminal sends to network.
The logic channel that is positioned at the top of transmission channel and is mapped to transmission channel comprises Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), MBMS point-to-multipoint control channel/multicast control channel (MCCH), MBMS point multipoint message traffic channel/multicast service channel (MTCH) etc.
Fig. 3 illustrates according to the transmission of prior art on control channel.
Physical channel is by forming in a plurality of subframes of arranging on the time shaft and a plurality of subcarriers of arranging on frequency axis.At this, single subframe comprises a plurality of symbols on the time shaft.A subframe is made up of a plurality of Resource Block, and each Resource Block comprises a plurality of symbols and a plurality of subcarrier.In addition, each subframe can be used the specific subcarrier of special symbol (for example, first symbol) in the corresponding subframe of physical downlink control channel (PDCCH) (that is L1/L2 control channel).A sub-frame duration is 0.5ms.Transmission Time Interval (TTI) as the unit interval that is used to send data is and two corresponding 1ms of subframe.
Fig. 4 is the block diagram that is used for the network configuration of cell broadcast service.As shown in Figure 4, the CBS informed source is in a plurality of Cell Broadcast Entities (being designated hereinafter simply as CBE) that are connected to CBC (being designated hereinafter simply as CBC).CBE is divided into a plurality of pagings with CBS message.CBC is a node by the core net of management CBS message operation dispatching function.The interface that Iu-BC is to use coverage Radio Broadcasting Agreements (being designated hereinafter simply as SABP) to define between CBC and RNC.CBC can give RNC with the broadcast order of new information, perhaps uses SAB to make previous broadcast be modified or stop.The CBS message operation dispatching function that RNC transmits CBC, and use the BMC agreement to carry out broadcast capability to send a message to specific cell.RNC has broadcast/multi broadcast interconnecting function (being designated hereinafter simply as BMC-IWF) on the BMC layer, with to from CBC message transmitted and information and executing explanation function.UE receives the CBS message of UTRAN broadcasting.The example of the BMC message of using in the BMC agreement is the CBS message of transmission user profile, the scheduling message that promotes UE reception CBS message and the transmission CBS41 message from the short message of ANSI41 network delivery.All message by such as the logic channel folk prescription of CTCH (CTCH Common Traffic Channel) to sending to UE from UTRAN.The information that UE can use UTRAN to pass through in the scheduling message that CTCH (CTCH Common Traffic Channel) sends reduces owing to carry out the electric weight that discontinuous reception (being designated hereinafter simply as DRX) consumes.
In conventional cell broadcast service (CBS) scheme, send the schedule information relevant with warning message by CTCH Common Traffic Channel (CTCH).Therefore, in the prior art, this causes a serious defective: because terminal receives Traffic Channel usually after at first receiving control channel, so terminal can not be rapidly or receive the schedule information of warning message apace.

Embodiment
An aspect of of the present present invention be the present inventor to the problems referred to above of this area and the understanding of defective, and below will explain in further detail.Based on this understanding, characteristics of the present invention have been developed.
The present invention can be embodied in the 3GPP communication technology (particularly, at universal mobile telecommunications system (UMTS)), communicator and the method thereof.Yet the present invention can also be applied to all wire/wireless communications that can use at technical scope of the present invention.
Below, provide with reference to the accompanying drawings according to a preferred embodiment of the invention structure and the description of operation.
Fig. 5 illustrates the warning message transmission course according to the first embodiment of the present invention.In the present invention, logic channel that can be by broadcast control message to a plurality of terminals or with transmission channel (that is downlink sharied signal channel, of logic channel mapping; DL-SCH) send warning message (below will be called as ETWS (earthquake and tsunami warning system) message).
As shown in Figure 5, in the first step, terminal (UE) can be by the logic channel receiving system information such as Broadcast Control Channel (BCCH).If the system information that receives comprises the schedule information (or configuration information or with the relevant any out of Memory of (ETWS) message of reporting to the police) of warning (ETWS) message, then terminal can be for further processing, and receives warning (ETWS) message.Yet if the system information that receives does not comprise the schedule information of warning (ETWS) message, terminal can not be for further processing.At this, schedule information can comprise the special time period that sends (ETWS) message of reporting to the police.That is, schedule information can comprise about when sending the special time information of warning (ETWS) message.
In second step, terminal can receive or the physical downlink control channel (PDCCH) of special time window/time period that monitoring distributes for the transmission of (ETWS) message of reporting to the police according to the schedule information that receives.At this, terminal can be passed through physical downlink control channel (PDCCH) and receive ad hoc wireless networks temporary identifier (RNTI).
In the 3rd step, if during second step, in physical downlink control channel, indicate the ad hoc wireless networks temporary identifier (promptly, ETWS RNTI), then terminal can be by receiving (ETWS) message of reporting to the police with physical downlink control channel (PDCCH) corresponding downstream link sharing channel (DL-SCH).Yet if do not indicate the ad hoc wireless networks temporary identifier in physical downlink control channel during second step, terminal can not receive (ETWS) message of reporting to the police by downlink sharied signal channel.
At this, send or receive (ETWS) message of reporting to the police by transmission channel, transmission channel and logical control channel (that is shared logic the channel) mapping that is used for the common receiving control information of a plurality of terminals such as downlink sharied signal channel (DL-SCH).Therefore, the base station can send (ETWS) message of reporting to the police by logical control channel and downlink sharied signal channel.In addition, terminal can receive (ETWS) message of reporting to the police by logical control channel and downlink sharied signal channel.
At this, base station (eNB) can use HARQ (mixed automatic repeat request) operation of downlink sharied signal channel to resend warning (ETWS) message.Therefore, if terminal can not receive warning (ETWS) message fully, then terminal can use the HARQ operation retry to receive (ETWS) message of reporting to the police.System information and/or warning (ETWS) message can be divided into main ETWS notice and less important ETWS notice.That is, can send main ETWS notice and less important ETWS notice to terminal simultaneously.Perhaps, under specific circumstances, terminal can receive less important ETWS notice after receiving main ETWS notice.
Fig. 6 illustrates warning message transmission course according to a second embodiment of the present invention.
As shown in Figure 6, in the first step, terminal can receive or monitor the physical downlink control channel (PDCCH) of the special time window/time period that is used for transmission warning (ETWS) distribution of messages according to the schedule information that receives.At this, terminal can be passed through physical downlink control channel (PDCCH) and receive ad hoc wireless networks temporary identifier (RNTI).More specifically, terminal can be monitored the special time window termly according to the ETWS cycle (period) that receives (ETWS) message of reporting to the police.The ETWS cycle can be a paging DRX (discontinuous reception) cycle or a plurality of paging DRX cycle, and described paging DRX cycle is provided with from the base station paging receiving termly for terminal.Therefore, if the ETWS cycle is identical with paging DRX cycle, then terminal can be based on paging DRX cycle monitoring alarm (ETWS) message.
In second step, if indicating the ad hoc wireless networks temporary identifier during the first step in physical downlink control channel, then terminal can be by receiving (ETWS) message of reporting to the police with physical downlink control channel (PDCCH) corresponding downstream link sharing channel (DL-SCH).Yet if do not indicating the ad hoc wireless networks temporary identifier during the first step in physical downlink control channel, terminal can not receive (ETWS) message of reporting to the police by downlink sharied signal channel.
At this, base station (eNB) can use HARQ (mixed automatic repeat request) operation of downlink sharied signal channel to resend warning (ETWS) message.Therefore, if terminal does not receive (ETWS) message of reporting to the police fully, then terminal can use the HARQ operation retry to receive (ETWS) message of reporting to the police.System information and/or warning (ETWS) message can be divided into main ETWS notice and less important ETWS notice.That is, can send main ETWS notice and less important ETWS notice to terminal simultaneously.Perhaps, under specific circumstances, terminal can receive less important ETWS notice after receiving main ETWS notice.
The present invention can provide a kind of method that receives warning message in mobile communication system, and described method comprises: receive the control information relevant with warning message by control channel; And receive described warning message based on the control information that receives by downlink channel, wherein, described warning message is earthquake and tsunami warning system (ETWS) message, described control information is system information (SI), described control channel is Broadcast Control Channel (BCCH), described control information comprises the schedule information of warning message, described schedule information comprises the time period information that is used for warning message, described downlink channel is downlink sharied signal channel (D-SCH), described control information comprises main ETWS notice and less important ETWS notice, and before receiving described less important ETWS notice, at first receive described main ETWS notice, and described warning message is based on, and the information of indicating on the physical downlink control channel receives by DL-SCH.
That is, the present invention has the effect that receives warning message when realizing effectively utilizing Radio Resource with the minimum delay effectively.
The disclosure can be provided in the possible solution that is used for ETWS (earthquake and tsunami warning system) among the E-UTRAN.Usually, the use of ETWS message is considerably less.Therefore, in order to save electric weight, UE does not need to monitor ETWS message at every turn.Yet in case earthquake and tsunami take place, the frequent updating that helps the user to receive earthquake and tsunami will be useful.For above-mentioned reasons, the disclosure can provide two steps to come the minimise battery power consumption.For the first step, eNB can send the main indication of earthquake and tsunami warning to UE.Then, for second step, eNB can send the transmission/renewal of earthquake and tsunami warning to UE.Particularly, eNB can provide main indication when receiving first warning.Afterwards, eNB can prepare second and go on foot the renewal that sends warning.UE can check the main indication that whether has warning termly when carrying out normal running.If there is the main indication of reporting to the police, then UE carries out second renewal that goes on foot below therefore receiving.At this, during the first step, the disclosure proposes UE and should only report to the police with the minimal effort inspection when carrying out normal running.On the other hand, during second step, UE must receive the warning message that imports into best endeavors.
To provide the more detailed description of the first step below.Should notify the beginning of warning as quickly as possible.When UE was idle, the beep-page message with warning reason can be a solution.Yet in most of the cases, beep-page message can not arrive UE under connection mode, and reason is that the UE under the connection mode can not monitor for pages message.Therefore, the following solution UE that can be used to connect.
First selection is by changing system information indication warning beginning.On the common logical that is exclusively used in the broadcasting warning, send the renewal of reporting to the police.If report to the police beginning, the system information of then carrying the specific common signal channel configuration of ETWS will be included in the system information block (SIB).Consequently, UE is with the change of receiving system information for this reason.In this scheme, if finding the system information of carrying the specific common signal channel configuration of ETWS, UE is included among the SIB, then can notify UE to report to the police and begin.Then, UE proceeded to for second step.
Second selection is the beginning by using the specific RNTI indication of ETWS to report to the police on PDCCH.In most of the cases, the UE of connection will frequently monitor the PDCCH with some RNTI.Therefore, the disclosure proposes to use the specific RNTI of ETWS.Therefore, if UE finds the specific RNTI of ETWS on PDCCH, then can notify UE to report to the police and begin.Then, UE can carry out for second step.At this, when reporting to the police beginning, eNB can repeat the specific RNTI of ETWS in the specific duration on available PDCCH, receives the specific RNTI of ETWS to guarantee all UE.On the other hand, when UE read PDCCH, except other RNTI, UE may need to check the indication of the specific RNTI of ETWS on the PDCCH.In this was selected, UE should check additional RNTI.In order to alleviate it, eNB can provide some periodicity chances that allow to send the specific RNTI of ETWS.
To provide the more detailed description in second step below.In case give UE, will be helpful to each user's frequent updating earthquake and tsunami with alert notice.Use in the first step under the situation of beep-page message, after the beginning of reporting to the police, several beep-page messages will cause overload.In addition, can transmit by the Multimedia Message among the E-UTRAN warning is provided.Therefore, disclosure proposition is not on PCCH but goes up transmission/renewal that realization is reported to the police in common logical (for example, the specific MTCH of ETWS, CTCH or CCCH).At this, common logical is mapped to DL-SCH.
Can dispatch the ETWS message on the DL-SCH termly in each ETWS cycle.At this, the ETWS cycle is not specific to UE's but specific to the sub-district.After the main indication that receives warning, UE can receive DL-SCH, to receive the ETWS message in each ETWS cycle.ETWS message can comprise the details of warning and/or the renewal of warning.
In addition, PDCCH can help UE to save electric weight.If send ETWS message on DL-SCH, then PDCCH can indicate ETWS RNTI.ENB can carry out ETWS message on DL-SCH HARQ retransmits.UE monitors PDCCH termly in time window, whether have ETWS RNTI to check.If UE finds ETWS RNTI, then UE receives ETWS message on DL-SCH.If UE does not find ETWS RNTI in time window, then UE can carry out DRX, and can wait for up to next time window.
HARQ on DL-SCH retransmitted, eNB can repeat to send ETWS message.In addition, eNB can send new ETWS message sometimes.Therefore, can provide this lastest imformation by ETWS message or PDCCH.
Should provide ETWS schedule information to UE.System information can provide the ETWS schedule information on BCCH.If beep-page message is used to carry the main indication of warning, then beep-page message can also only provide ETWS schedule information to idle UE.In addition, can also on system information, carry the ETWS channel configuration on the BCCH.
In a word, two steps that the disclosure provides transmission/reception ETWS message (promptly, step 1: the main indication of earthquake and tsunami warning, step 2: the transmission/renewal of earthquake and tsunami warning), and propose UE and comprise the main indication that the specific common signal channel configuration of ETWS receives warning among the SIB by finding out, perhaps by on PDCCH, receiving the specific RNTI of ETWS, the common logical that is mapped to DL-SCH is used to carry ETWS message, the beginning in case report to the police, eNB just provides the periodicity chance to carry ETWS message on DL-SCH, and UE monitors the periodicity chance in each ETWS cycle, the PDCCH indication ETWSRNTI relevant with DL-SCH.The beep-page message of system information on the BCCH and/or main indication transmits the ETWS schedule information, and the system information on the BCCH is carried the ETWS channel configuration.
In some cases, if system information is carried main notice and less important notice, then may not satisfy the delay requirement of main notice.This is because BCCH revises the typical length in cycle greater than delay requirement (that is, 4 seconds).Yet the disclosure propose to realize such scheme, because if carry main notice on BCCH, E-UTRAN will only have a kind of pass through mechanism for the ETWS notice and the type not considering to notify (that is, mainly notice or less important notice).In addition, if this is the case, then identical safe class (that is, based on digital signature safely) can be applied to main notice and less important notice.
What a kind of BCCH of satisfying went up the main delay requirement of notifying may be to have the ETWS particular B CCH that carries ETWS message to revise the cycle, revises the cycle such as ETWS.The length that ETWS revises the cycle can be equal to or greater than the length of paging DRX cycle, and should revise the length in cycle less than normal BCCH.At this, ETWS revises the operation that the cycle does not influence normal system block of information, does not change any other system information because BCCH goes up the transmission of ETWS message.Only ETWS message is followed ETWS and is revised the cycle on BCCH.Should be noted that, will on other SIB except the SIB that carries ETWS message, broadcast the configuration of the ETWS transmission that comprises ETWS modification Cycle Length.The SIB that carries the configuration of ETWS transmission follows normal BCCH and revises the cycle.
Should be noted that the system information of mentioning in the disclosure can be divided into Master Information Block (MIB) and a plurality of system information block (SIB).MIB comprises the most basic of the limited quantity that obtains the out of Memory needs from the sub-district and the parameter of frequent transmission, and sends MIB on BCH.Can in system information (SI) message, carry the SIB except system information block type 1, and can be by the schedule information flexible configuration SIB that comprises in the system information block type 1 to the SI message mapping.Use dynamic dispatching in cycle time of occurrence territory window (being called as the SI window), to send SI message.The time-domain scheduling that UE is detailed according to acquisition that the SI-RNTI on the PDCCH is decoded (and out of Memory, for example, frequency domain dispatching, the transformat of use).Single SI-RNTI is used for system information block type 1 and the addressing of SI message.The transmission cycle of system information block type 1 configuration SI length of window and SI message.System information block type 10 can comprise ETWS mainly to be notified, and system information block type 11 can comprise the less important notice of ETWS.More specifically, the field that comprises in SIB Class1 0 and/or the SIB Class1 1 can comprise the source of indication ETWS notice and the parameter or the value of type, the variation of ETWS notice, the type of alarm of ETWS notice, the security information that is used for the ETWS notice and the segment number of ETWS warning message section etc.
Purpose of the present disclosure is to the transmission paging information (or message) of the UE under the RRC_IDLE pattern and/or the UE reporting system information under UE under the RC_IDLE pattern and RRC_CONNECTED pattern changes and/or ETWS mainly notifies and/or the less important notice of ETWS.Provide beep-page message to the upper strata, the upper strata can be initiated RRC and be connected foundation (for example, receiving the calling of importing into) in response.E-UTRAN can initiate page procedure by sending beep-page message when the UE paging.E-UTRAN can also indicate the change of system information and/or ETWS is provided in beep-page message notice.That is, if exist, then ETWS mainly notifies and/or the indication of the less important notice of ETWS can be included in some field of beep-page message.
