System information block 11 (SIB11) carries the assistant notification for early warning ETWS, comprises message identification numbers, sequence number, the segment information of alarm information, fragment number, section, data coding scheme etc.
In said system information, in the LTE system, the terminal of RRC_CONNECTED state will be carried out data transmit-receive, just must know the MIB of current area, SIB1 and SIB2 message.In the LTE-A system, there are a plurality of CC a residential quarter, considers the requirement of compatible LTE terminal, need to broadcast one on each CC and overlap independently system information, and the system information on each CC may be different: such as frequency information, and the configuration of PHICH etc.Therefore, the LTE-A terminal need to be obtained the upper up-to-date system information of each CC before a plurality of CC of use carry out transfer of data.
Carrier sense mechanism in the LTE system is:
As shown in Figure 2, be the structural representation of descending sub frame, each descending sub frame is comprised of the OFDM symbol, and front several OFDM symbols of descending sub frame are control character, is used for the bearing downlink control signal, and the channel of bearing downlink control signal is called the PDCCH channel.All the other OFDM symbols carry downlink datas, the physical layer channel of bearing downlink data is called the PDSCH channel.Control signal comprises: to the schedule information of this descending sub frame and corresponding sub-frame of uplink and relevant HARQ information etc.Terminal determines whether distributed resource in corresponding subframe by the control signal that receives descending sub frame.If distributed resource, terminal obtains the temporal frequency position of resource according to the indication of dispatch, and carries out the data transmitting-receiving.In the LTE system, each residential quarter only has a descending carrier, so terminal only need to be monitored PDCCH and a PDSCH on the descending carrier.
In the LTE-A system, introduced the CA technology, a residential quarter possible configuration a plurality of CC, N for example.The terminal of LTE-A may use M CC to carry out transfer of data simultaneously, and wherein M is less than or equal to N.When the data volume of LTE-A terminal transmitting-receiving is larger, need carry out transfer of data at many CC simultaneously.This moment, terminal was monitored PDCCH and the PDSCH on a plurality of CC simultaneously.In the little situation of terminal data amount, monitoring simultaneously a plurality of CC has not just had too many necessity.Stop to be conducive to terminal power saving to the receiving the decode of obsolete CC.In order to make things convenient for following description, CC or CC group that terminal is received the decode are defined as Anchor CC.
Therefore, the carrier sense mechanism in the LTE-A system is:
Generally, PDCCH and the PDSCH on the terminal monitoring Anchor CC;
When having mass data to receive and dispatch, the CC that network is being monitored by terminal sends control signaling to terminal, requires terminal to increase the quantity of the CC that monitors;
After terminal is received above-mentioned signaling, start the monitoring of corresponding CC;
Network and terminal communicate at a plurality of CC.
Terminal has a precondition in the enterprising row data transmitting-receiving of CC: terminal need to be known the up-to-date system information of this CC.But each CC only can broadcast system information corresponding to this CC, and UE only can monitor Anchor CC before the control signal of receiving the activation CC monitoring that network sends.This has just caused UE receiving when activating the control signal that CC monitors, and may not know the up-to-date system information of the CC that is activated.
If terminal just begins to receive the system information on the corresponding CC after receiving that CC activates signaling, then before the reception of completion system information, terminal can not be on this CC transceiving data.The transmission of system information is periodic, and the transmission cycle of MIB and each SIB is not waited from tens to the hundreds of millisecond.That is to say, after terminal receives that CC activates signaling, may need the system information through dozens or even hundreds of millisecond to read after the process, could be in the enterprising row data transmitting-receiving of corresponding CC.As seen, if terminal after receiving that CC activates signaling, just begins to receive the system information on the corresponding CC, with introducing larger time delay, in order to address this problem, in the LTE-A system, introduced following system information monitoring mechanism.
System information monitoring mechanism in the LTE-A system is:
Introduced the CA technology in the LTE-A system, the terminal of LTE-A need to after accessing the LTE-A residential quarter or switching to new LTE-A residential quarter, read in this residential quarter the system information on each CC immediately in order to receive and dispatch by rapid data on a plurality of CC.And behind generation systems information-change on each CC, again read the system information on this CC.This mechanism requires the terminal of LTE-A can in time obtain system information Notification of Changes on each CC of current area.
The informing mechanism of the system information change in the LTE system is:
Outside ETWS (Earthquake and Tsunami Warning System, earthquake and tsunami warning system) message, the change of system information can only occur in specific radio frames, and is definite by the modification cycle (modification period).Within a modification cycle, system information may send repeatedly, and the system information content that repeatedly sends is identical.System information can only change after the border in the cycle of modification, and the boundary definition of revising the cycle is as follows: SFN mod m=0.Wherein, SFN is System Frame Number, and m is the modification cycle, and unit is radio frames.
When network need to change all or part of system information, it at first needed to send " system information change indication " to terminal, and notification terminal changes the system information that occurs, and notification procedure may need to continue a modification cycle.Revise the cycle at the next one, network just can send the system information after the renewal.Above-mentioned rule is system information change schematic diagram as shown in Figure 3.After receiving system information change indication, terminal is revised the system information after locating to read renewal of beginning in cycle immediately at the next one.Before terminal was obtained new system, terminal continued to use old system information.
Network comes to send " system information change indication " to the terminal that is in RRC_IDLE and RRC_CONNECTED state with beep-page message.If terminal has been received the beep-page message that comprises " systemInfoModification ", can revise the boundary in cycle at the next one and change with regard to knowing system information." system information change indication " only can the notification terminal system information will change, and can not indicate which or which system information to change to terminal.
The change of some system information can not trigger the transmission of the beep-page message that comprises " systemInfoModification ", such as the change of ETWS.Terminal can determine by the following method whether the system information of depositing is effective, in the situation of not receiving the systemInfoModification indication, terminal need to be within a modification cycle, at least read beep-page message modificationPeriodCoeff time, in the hope of finding the systemInfoModification indication.
If do not read beep-page message, terminal thinks that system information will can not change within the next one modification cycle.If terminal reads the beep-page message that comprises the systemInfoModification indication, just think that system information will change in the next one is revised the cycle.The introducing of systemInfoModification can be avoided frequently read system information of terminal, reduces the power consumption of terminal.
In addition, the LTE system triggers called service with paging and the notification terminal system information is about to change.Beep-page message is dispatched by PI-RNTI.Terminal in the network is decoded to the PDCCH channel specific constantly, obtains beep-page message.
As mentioned above, under technique scheme, the terminal of LTE-A can't the time obtain the system information Notification of Changes of each CC of current area.In the little situation of data volume, the LTE-A terminal is only monitored the PDCCH message on the Anchor CC.Certain CC in the residential quarter, calling this CC in the following text is CC_change, when its system information changed, the beep-page message that is used for the change of notification terminal system information only can send at CC_change.If the Anchor CC of LTE-A terminal is not CC_change, it can't be known has the system information of CC to change, and then to cause the system information of the CC_change that terminal preserves be not up-to-date.When network need to activate the data transmit-receive of this terminal on CC_change, terminal was used invalid CC configuration information, will cause transfer of data to make a mistake.
Therefore be necessary to propose corresponding technical scheme, terminal can realize monitoring to a plurality of CC in the resolution system, in time finds the variation of system information and the problem of upgrading.
