Description

System information transmission, acquisition methods and equipment
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of system information transmission, acquisition methods and equipment.Background technology
Along with user terminal (User Equipment, UE) fast development and user constantly increase the demand of data service rate and capacity, traditional macro base station (Macro evolved NodeB, Macro eNB) individual layer overlay network can not meet this situation.Therefore, the mode that 3GPP has introduced layering networking solves this problem: by hot spot region, the little overlay environment such as family's indoor environment, working environment lays some lower powered base stations (comprising the forms such as Femto/Pico/ relaying), obtain the effect of cell splitting, make operator to provide more high data rate, business more cheaply for user.Macrocell in layering networking situation (Macro Cell) provides basis to cover, and small-cell (Small Cell) provides additional system capacity.
Long Term Evolution (Long Term Evolution, LTE) system information in system is divided into Master Information Block (MasterInformationBlock, MIB) and multiple system information block (SystemInformationBlocks, SIB), comprise that SIB1 is to SIB15).Following table 1 has been described the major function of each system information:
Figure BDA00002539146700011
Figure BDA00002539146700031
Table 1
For the consistency that guarantees that UE and network are understood system information, introduce the concept in system information modification cycle, system information content within the modification cycle can not change, and system information modification can only be from the zero hour in next system information modification cycle.When UE learns system information after changing, revise and monitor new system information the zero hour in cycle at the next one.LTE system is supported the advice method of two kinds of system information-changes:
The first, network side uses the UE changing system information of beep-page message notice Idle state and connected state, and UE starts to monitor new system information in the next one modification cycle;
The second, network side is carrying system information-change label (systemInfoValueTag) information in the SIB1 sending, if the difference that the system information that UE reads changes label and stores before represents that system information changes, need to again read; The term of validity of UE storing system information is 3 hours, if exceed this time, UE needs read system information again.
For the change of ETWS information (being included in SIB10-SIB11) in system information and CMAS information (being included in SIB12), allow UE not adopt the time point that reads stipulating in system information changing process.There is the UE that receives ETWS or CMAS information capability to detect whether have ETWS or CMAS Notification of Changes information by beep-page message, while monitoring Notification of Changes information, read immediately the particular content in ETWS and CMAS place system information block.
The system information that the UE of connected state and Idle state only needs it reads and upgrades, and can not read and upgrade for its unwanted system information.
Because network side does not send public information (as system information) on dependent work (non-standalone) community, thereby the resource that the public information saving can be taken is for the transfer of data of UE.But for the community of transmitting system information not, the UE of Idle state cannot be resident, so non-standalone community does not need to support that the UE of Idle state works thereon, and only needs the UE of Supporting connectivity state to work thereon.Therefore, non-standalone community does not need the system information that the UE that only offers Idle state is used to offer the UE of connected state, and the system information that these UE that offer Idle state use comprises: SIB3 is to SIB8, SIB14.But for can offer connected state UE use other system information, remain need to offer connected state UE use.
The UE of connected state works and mainly contains following three kinds of modes on non-standalone community:
Mode 1: carrier aggregation mode.In existing carrier aggregation mode, non-standalone community can be used as the UE of auxiliary community (Scell) configuration to connected state, thereby UE can utilize the resource of non-standalone community to carry out work.And because existing carrier aggregation mode is only supported main plot (PCell) and the SCell scene at identical eNB, therefore which can only be used for non-standalone community also the scene of (standalone) community that works alone that same eNB controls under covering.
Mode 2: connected state switching mode.The mode that the UE of the connected state of working on standalone community can enter non-standalone community by switching realizes on non-standalone community works.
Mode 3: carrying separate mode.Under which, a part of the UE of connected state carrying (Radio Bearer, RB) is split on Small Cell from Macro Cell, thereby the UE that realizes connected state can work on the Small of non-standalone Cell.The operative scenario of which is described as Fig. 1.In this scene, be different from existing carrier aggregation mode, Macro Cell and Small Cell can belong to different eNB.UE for safeguarding chain of command signaling bear (the Signalling Radio Bearer of transmitting-receiving of the control signal that the Radio Resource control (RRC) of UE connects, SRB) on the Macro Cell mainly controlling at Macro eNB, by Macro eNB and Mobility Management Entity (Mobility Management Entity, MME) connection, can be by user face data carrying (Data Radio Bearer, DRB) part or all of Small Cell that is separated to home base stations (Local eNB) of the data transmit-receive for UE of UE.While Macro eNB and Local eNB also can have the connection with gateway (Serving Gateway, S-GW), to realize the transfer of data of DRB separately.UE may have SRB(part RRC control signal to send by Small Cell on Local eNB), may there is no SRB(RRC control signal by all sending by Macro Cell) yet.
In current 36.304 agreements, stipulate that UE calculates beep-pager meeting (Paging Occasion, PO) formula, the PO of UE is according to the difference of the paging density nB value of system (time division duplex (TDD) or Frequency Division Duplexing (FDD) (FDD)), network settings, acquiescence paging cycle defaultPagingCycle length, UE mark (ID) and difference.
In simple terms, be directed to FDD system, the position that the PO of UE may occur in a radio frames, as following table 2, is directed to TDD system, and the position that the PO of UE may occur in a radio frames is as following table 3:
FDD:
Ns PO when i_s=0 PO when i_s=1 PO when i_s=2 PO when i_s=3
1 9 N/A N/A N/A
2 4 9 N/A N/A
4 0 4 5 9
Table 2
Ns PO when i_s=0 PO when i_s=1 PO when i_s=2 PO when i_s=3
1 0 N/A N/A N/A
2 0 5 N/A N/A

Table 3
To sum up, for the UE of the connected state of working on the non-standalone community of broadcast system information not, the UE of this connected state cannot obtain from non-standalone community its system information needing, and needs to consider how to allow these UE obtain and upgrade the system information on non-standalone community.

In the time that terminal works is on multiple communities, terminal can also be corresponding by other communities except non-standalone community SRB reporting terminal capacity information or system information obtain solicited message, wherein cell ID (i.e. the mark of this non-standalone community) corresponding to the needed system information of carried terminal, source base station receives terminal ability information or the system information of carrying cell ID and obtains after solicited message, if the community that this cell ID is corresponding belongs to source base station, source base station sends to terminal by needed terminal system information by this SRB, if the community that this cell ID is corresponding does not belong to source base station, source base station obtains solicited message by terminal ability information or system information and is transmitted to the target BS that this community belongs to, needed terminal system information is sent to source base station by target BS, and source base station sends to terminal by needed terminal system information by this SRB.
Preferably, if this non-standalone community belongs to source base station, source base station occurs after changing in the system information of needed this non-standalone community of terminal, and system information is after changing sent to terminal by dedicated signaling;
If this non-standalone community does not belong to source base station, target BS occurs after changing in the system information of needed this non-standalone community of terminal, and system information is after changing sent to source base station, and this information exchange is crossed inter-base station interface transmission; Source base station sends to terminal by system information after changing by dedicated signaling.
Preferably, if this non-standalone community belongs to source base station, source base station obtains and stops, after indication, stopping sending to terminal the system information of needed this non-standalone community of this terminal in the system information that receives terminal transmission;
If this non-standalone community does not belong to source base station, source base station obtains and stops after indication in the system information that receives terminal transmission, system information is obtained and stopped indication and be transmitted to target BS, and this information exchange is crossed inter-base station interface transmission, and carries the supplementary such as mark of source base station; Target BS stops sending to source base station the system information of needed this non-standalone community of this terminal, and source base station stops sending to terminal the system information of needed this non-standalone community of this terminal.
Terminal to report system information is obtained the mode that stops indicating can adopt following two kinds:
The first, display mode; Terminal sends RRC signaling to network side, and wherein carrying demonstration information no longer needs to issue relevant system information with indication;
The second, the hidden mode of showing; Terminal is that empty terminal ability information or system information obtained solicited message by sending content to network side, no longer needs to issue relevant system information to indicate.
The system information of terminal to report is obtained and is stopped can also carrying and needing network side to stop cell ID corresponding to system information issuing in indication.
The system information of terminal to report obtain stop indication can be carried in new independently RRC signaling, or using system information obtain stop indication be carried in existing RRC signaling and send to network side as new IE.
In step 20, network side is determined the system information that is operated in needed this non-standalone community of terminal on non-standalone community, and its another kind of implementation method is:

Preferably, network side occurs after changing in the system information of needed this non-standalone community of terminal, and system information is after changing sent to terminal by dedicated signaling.Concrete executive agent can be the base station under non-standalone community.
Preferably, the system information that network side sends at receiving terminal is obtained and is stopped, after indication, stopping sending to this terminal the system information of needed this non-standalone community of this terminal.Concrete executive agent can be the base station under non-standalone community.
Referring to Fig. 3, a kind of system information acquisition method that the embodiment of the present invention provides for end side, comprises the following steps:
Step 30: the system information that is operated in terminal on non-standalone community and receives needed this non-standalone community of this terminal that network side sends by dedicated signaling;
Step 31: this terminal is preserved the system information receiving.
Preferably, before the system information of needed this non-standalone community of this terminal sending by dedicated signaling at terminal reception network side, terminal can be obtained solicited message to network side reporting terminal capacity information or system information, and this terminal ability information or system information are obtained solicited message and indicate the system information of required this non-standalone community obtaining of this terminal.
The terminal ability information of terminal to report or system information are obtained in solicited message and can be comprised: the indication information of the system information of the required non-standalone community obtaining of this terminal; Further, can also comprise the cell ID corresponding to system information of the required non-standalone community obtaining of terminal.
Terminal can be obtained solicited message by new independently RRC signaling reporting terminal capacity information or system information; Or terminal is obtained solicited message using terminal ability information or system information and is carried in existing RRC signaling and sends to network side as new IE.
Terminal can be obtained solicited message by non-standalone community corresponding SRB reporting terminal capacity information or system information, wherein cell ID corresponding to the needed system information of carried terminal not, or, in the time that terminal works is on multiple communities, terminal can also be corresponding by other communities except non-standalone community SRB reporting terminal capacity information or system information obtain solicited message, wherein cell ID (i.e. the mark of this non-standalone community) corresponding to the needed system information of carried terminal.
Preferably, after the system information of needed this non-standalone community of this terminal sending by dedicated signaling at terminal reception network side, terminal receives the system information of needed this non-standalone community of this terminal after changing of network side transmission, and preserves system information after changing.
Preferably, terminal can obtained after solicited message to network side reporting terminal capacity information or system information, or receiving after the system information that network side issues, stop indication to network side reporting system acquisition of information, stop to this terminal transmitting system information with informing network side.
Terminal to report system information is obtained the mode that stops indicating can adopt following two kinds:
The first, display mode; Terminal sends RRC signaling to network side, and wherein carrying demonstration information no longer needs to issue relevant system information with indication;
The second, the hidden mode of showing; Terminal is that empty terminal ability information or system information obtained solicited message by sending content to network side, no longer needs to issue relevant system information to indicate.
The system information of terminal to report is obtained and is stopped can also carrying and needing network side to stop cell ID corresponding to system information issuing in indication.
The system information of terminal to report obtain stop indication can be carried in new independently RRC signaling, or using system information obtain stop indication be carried in existing RRC signaling and send to network side as new IE.
Be similarly the problem that solves the terminal being operated on non-standalone community and how to get the system information of this non-standalone community, the embodiment of the present invention provides another kind of system information acquisition method.
Referring to Fig. 4, the another kind of system information acquisition method that the embodiment of the present invention provides, comprises the following steps:
Step 40: the terminal being operated on non-standalone community is selected an adjacent cell, and this adjacent cell is standalone community;
Step 41: the adjacent cell of terminal and selection is set up after down-going synchronous, read system information from the system broadcast message of this adjacent cell.
Further, in step 41, if adjacent cell and non-standalone community that terminal is selected are alien-frequency district, before terminal and this adjacent cell are set up down-going synchronous, terminal need to be interrupted the transfer of data in this non-standalone community, the working frequency points of self is switched to the frequency at this adjacent cell place; Then, the adjacent cell of terminal and selection is set up down-going synchronous, and network side configuration or predefined measurement interval in, read system information from the system broadcast message of this adjacent cell.
Concrete, terminal is read system information from the system broadcast message of the adjacent cell of selection, and specific implementation can be as follows:
Terminal reads the information of MIB and the SIB1 of this adjacent cell from the system broadcast message of this adjacent cell;
Terminal obtains the schedule information of the system information self needing from SIB1, and obtains the corresponding system information of this adjacent cell broadcast according to this schedule information.
Read first after needed system information in terminal, the schedule information of the follow-up system information that can need according to self periodically reads corresponding system information, also can be to occur to go again read system information while change in call signaling indication mechanism information, be implemented as follows:
First, terminal and this adjacent cell are set up down-going synchronous;
Then, terminal is determined beep-pager meeting (PO) position of this adjacent cell, and this PO position indication network side sends the time of call signaling in adjacent cell;
Then, terminal is at the pager wireless net network temporary mark (P-RNTI) of this PO position probing self;
Finally, terminal reads the call signaling transmitting on this PO position in the time this P-RNTI being detected, and whether determine in this call signaling the change indication notice of carrying system information, if so, obtain the system information after changing of this adjacent cell broadcast according to this change indication notice.
Below in conjunction with specific embodiment, the present invention will be described:
Embodiment mono-:
In the present embodiment, UE has corresponding SRB on non-standalone community.
As shown in Figure 5 a, the flow process that system information is obtained is as follows:
Step 1: the UE of the connected state of working on non-standalone community, for the part SRB separate mode separating by carrier aggregation mode, switching mode and carrying, (a part of SRB is at Macro Cell, part SRB is at Small Cell), the UE of connected state has corresponding SRB on non-standalone community.For UE, if UE need to obtain the system information on certain non-standalone community, for example UE need to obtain the content of SIB15, UE sends RRC signaling (as being carried in terminal ability information (UECapabilityInformation)) to network side on SRB corresponding to non-standalone community, to indicate its ability information or system information to SIB15 to obtain request, to get the content of SIB15.
ENB corresponding to step 2:non-standalone community receives from the ability information to SIB15 of UE or system information and obtains after request, determines that UE need to obtain the SIB15 information on non-standalone community.If SIB15 correlation function is also supported in this non-standalone community, eNB crosses dedicated signaling (as be carried at RRC connect reshuffle in (RRCConnectionReconfiguration)) by SIB15 information exchange corresponding non-standalone community and sends to this UE.
As shown in Figure 5 b, the flow process that system information is upgraded is as follows:
Step 3: in the time of SIB15 information-change on non-standalone community, the indication that eNB sends according to terminal in step 1 is crossed dedicated signaling (as being carried in RRCConnectionReconfiguration) by the SIB15 information exchange after changing on non-standalone community and sent to this UE.
As shown in Figure 5 c, to obtain the flow process of termination as follows for system information:
The any time of step 4:UE after step 1, or receive after SIB15 information, if no longer need to receive or upgrade the information content of the SIB15 on non-standalone community, UE can send RRC signaling (as being carried in UECapabilityInformation) on SRB corresponding to non-standalone community, stop the issuing and upgrade of SIB15 of non-standalone community with informing network side, this termination indication can be: the indication information (as 1bit shows indication) of demonstration, or the hidden indication information showing (if do not sent or send empty ability information).ENB is receiving that from UE this SIB15 obtains termination indication, stops sending the SIB15 information on non-standalone community to this UE.
Illustrate: the system information needing for other UE to obtain, upgrade and obtain the process of describing in termination mode and this embodiment similar.Same, ability (or the system information request) information that UE reports or system information obtain stop indication be also can in new independently RRC signaling, send or be carried at other existing rrc messages in send to UE as new IE.Because process is similar, describe no longer one by one at this.
Embodiment bis-:
In the present embodiment, UE does not have corresponding SRB on non-standalone community.
As shown in Figure 6 a, the flow process that system information is obtained is as follows:
Step 1: the UE of the connected state of working on non-standalone community, under carrying separate mode, the UE of connected state does not have corresponding SRB on non-standalone community, or the mode separating by mode or the carrying of carrier aggregation, on non-standalone community, there is corresponding SRB, but not transmitting system information acquisition request on the SRB of community corresponding to needed system information of UE.As, UE need to receive the Home eNodeB name information (SIB9) on non-standalone small-cell, UE can send RRC signaling (as being carried in UECapabilityInformation) on the SRB of macrocell, to indicate its ability information or system information to SIB9 to obtain request, to get the content of SIB9.In RRC signaling, carry the cell ID that SIB9 is corresponding, being used to specify is the SIB9 information that will obtain which community.
Step 2:eNB receives the ability information to SIB9 or the system information of UE transmission and obtains after request, determine according to the cell ID carrying after the SIB9 information that has respective cell (being non-standalone community) on this eNB, the SIB9 information of Jiang Gai community and this cell ID send to this UE by dedicated signaling (as being carried in RRCConnectionReconfiguration).
As shown in Figure 6 b, the flow process that system information is upgraded is as follows:

Embodiment tetra-:
In the present embodiment, UE reads after the ETWS/CMAS indication in the call signaling that adjacent cell sends, and obtains corresponding system information;
The UE of the connected state of working on non-standalone community, due to network side not transmitting system broadcast message and call signaling on non-standalone community, cannot obtain by Broadcast Control Channel (BCCH) or Paging Control Channel (PCCH) the system information indication of upgrading in non-standalone community.
For ETWS or these public system informations of CMAS of large regional broadcast, can be by reading the BCCH of adjacent cell and/or the mode of PCCH obtains, specific as follows:
Step 1:UE and adjacent cell are set up down-going synchronous;
UE can complete mobility measurements with frequency/alien-frequency district signal strength/quality and assesses by measuring, and reports network side and carry out minizone switching.For co-frequency neighbor cell, need only UE for measuring with frequency, the adjacent cell on UE and same frequency is just in synchronous regime; For the UE that meets different-frequency measure condition, the time rule of measuring alien frequencies is set as there is 6ms as different-frequency measure gap (gap) in every 40/80ms.For the measurement of alien-frequency district, first to read the synchronizing signal of community, Bing Yugai sets up down-going synchronous in community;
Step 2:UE is known beep-pager meeting (PO) position of adjacent cell;
UEYu sets up community after down-going synchronous, can:
Directly monitor call signaling, the subframe 0,4,5,9 that is each radio frames for this PO position of Frequency Division Duplexing (FDD) (FDD), the subframe 0,1,5,6 that is each radio frames for this PO position of time division duplex (TDD) in most possible PO position;
Refinement, UE can read the system information SIB2 of this adjacent cell, obtains acquiescence paging cycle defaultPagingCycle, paging density value nB(value is 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, wherein T=defaultPagingCycle), and according to most possible radio frames and the subframe that sends call signaling of Cell System Frame Number judgement, and carry out the detection of P-RNTI.Such as:
NB is less than the situation of T, be not can occur beep-pager meeting in each radio frames, UE determines according to paging formula the radio frames position that PO occurs according to paging density, and at the subframe 0(of these radio frames only for TDD)/subframe 9(is only for FDD) and on carry out the detection of P-RNTI;
NB equals the situation of T, in each radio frames, can there is beep-pager meeting, and only at subframe 0(only for TDD)/subframe 9(is only for FDD) and position, UE can be at the subframe 0(of each radio frames only for TDD)/subframe 9(is only for FDD) detect P-RNTI;
NB is greater than the situation of T, and each radio frames all there will be (nB/T) individual PO position, and UE can detect P-RNTI according to the paging subframe position of agreement regulation in each radio frames.
In existing protocol, for ETWS and CMAS information, require at least to receive once in each defaultPagingCycle, the minimum value of defaultPagingCycle is 320ms.Said method can meet ETWS and the minimum reception of CMAS requirement completely.
Step 3:UE is at corresponding PO position probing P-RNTI;
Step 4: read corresponding call signaling in the time that UE detects P-RNTI, and resolve the change indication notice of wherein whether having carried system information.Indication notice may be as follows:
etws-Indication ENUMERATED{true}
OPTIONAL,--Need ON
cmas-Indication-r9 ENUMERATED{true}
OPTIONAL,--Need ON
Wherein the change of ETWS is indicated corresponding to SIB10 and SIB11, and the change of CMAS is indicated corresponding to SIB12.
Only, in the time that UE detects that changing indication notifies, just go further to decode in adjacent cell and change the corresponding system information of indication.First decode system information need to read the time domain deployment position of each system information in SIB1, then receives broadcast channel content in corresponding window, and solves actual system information content.
Embodiment five:

Step 2: receive that ability information to SIB15 or system information obtain the source eNB of request and find that community corresponding to SIB15 is under a target eNB, source eNB is transmitted to target eNB by this ability information or the system information request of obtaining by inter-base station interface.
Step 3: target eNB is received from the ability information to SIB15 or the system information of source eNB forwarding and obtained after request, according to cell ID, the SIB15 information exchange on non-standalone community is crossed to inter-base station interface and send to source eNB, and carry the supplementarys such as this cell ID.
Step 4: source eNB receives after the SIB15 information from target eNB, and this SIB15 information and cell ID are sent to this UE by dedicated signaling (as being carried in RRCConnectionReconfiguration).
As shown in Figure 8 b, the flow process that system information is upgraded is as follows:
Step 5: when the target eNB that sends SIB15 information to source eNB finds that after this SIB15 information-change, target eNB sends to source eNB by system information after changing by inter-base station interface, the wherein more information such as new logo of portability cell ID and SIB15.
Step 6: the SIB15 information after changing from target eNB that source eNB receives, sends to this UE by SIB15 information after changing and cell ID by dedicated signaling (as being carried at RRCConnectionReconfiguration) according to the indication receiving from UE in step 1 and cell ID.
As shown in Figure 8 c, to obtain the flow process of termination as follows for system information:
Any time of step 7:UE after step 1, or receive after SIB15, if no longer need to receive or upgrade the SIB15 information on non-standalone community, UE can send RRC signaling (as being carried in UECapabilityInformation) on the SRB of macrocell, stops the issuing and upgrade of SIB159 of non-standalone community with informing network side.
UE SI reporting B15 obtains the mode that stops indicating and comprises:
Display mode.UE no longer needs SIB15 information by demonstration information (as 1bit) indication in RRC signaling;
The hidden mode of showing.UE can send empty information or not send GL information (or system information request of obtaining) in ability information (or system information request of obtaining), to indicate it no longer to need SIB15 information.
The SIB15 that UE reports obtains and stops also carrying the cell ID that SIB15 is corresponding in indication.
Step 8: source eNB is receiving that from UE this SIB15 obtains termination indication, if find, this termination indication is the SIB15 corresponding to target eNB Shang community, source eNB is determining under it there is no other UE after target eNB request SIB15 information, this SIB15 is obtained to stop indicating be transmitted to target eNB.Target eNB, according to the termination indication of receiving, stops sending the SIB15 information on non-standalone community to source eNB.
