Description

A kind of system information update method and device

Technical field

The present invention relates to advanced long-term evolution system, particularly relate to the technical field of multicarrier system information updating in advanced long-term evolution system.

Background technology

LTE (longtermevolution, long evolving system) version 8/9 is a single-carrier system, one community has and only has a descending carrier, system message sends on this descending carrier, system message includes MIB (masterinformationblock, Master Information Block), SIB (systeminformationblock, system information block) 1-13, wherein Master Information Block is at BCH (broadcastchannel, broadcast transmission channel) upper transmission, system information block 1 by fixed time at DL-SCH (Downlink-sharedchannel, DSCH Downlink Shared Channel) upper transmission, the delivery time of system information block 2-13 is indicated by schedule information, schedule information is positioned on system information block 1. system information block 1 also includes the system information more new logo (systemInfoValueTag) updated for system information. the system update process of R8/9 is as follows:

Network side: as eNB (evolvedNodeB, evolved base station) initiate system information change time, first at a MP (ModificationPeriod, amendment interval) in, it is called MPn (ModificationPeriodn without loss of generality, notice interval), the all relevant user equipment of paging, the subscriber equipment under (RRC-CONNECTED) state is connected including RRC free time (RRC-IDLE) state and RRC, then from next MP, it is called MPn+1 (ModificationPeriodn+1 without loss of generality, update interval), start to update system message, including the systemInfoValueTag updated in System information block 1.

UE side: under RRC-CONNECTED state, UE can attempt receiving beep-page message in MPn, if comprising system information modification mark (systemInfoModification) in beep-page message, then UE starts receive system message and update at MPn+1. UE also can periodic test system information more new logo systemInfoValueTag, such as verify every 3 hours that in systemInfoValueTag and UE, whether existing systemInfoValueTag identical in SIB1, if difference, updates system message.

LTE version 10, i.e. LTE-A (LTE-Adavanced, advanced long-term evolution system), be a multicarrier system. Running multiple descending CC (componentCarrier, component carrier) in community, UE can also configure multiple downlink component carrier simultaneously. When the system information of any downlink component carrier changes, the UE of this downlink component carrier is used to need to update. According to current standard knots opinion, in the descending carrier that UE runs, one of them is called PCC (primarycomponentcarrier, principal component carrier wave), other are called SCC (secondarycomponentcarrier, from component carrier), if the system message of PCC changes, so UE can adopt the update method in LTE version 8/9, namely first receives beep-page message to obtain system information change notification, then updates system message.

At present, system information for the SCC of multicarrier system updates two kinds of solutions of existence: scheme 1 is dedicated signaling scheme, by RRC (radioresourcecontrol, wireless heterogeneous networks) signaling notify UE system information change and change system information, this needs the cell that definition is new, it is required for sending a dedicated signaling to each subscriber equipment, causes signaling burden. And, network side is renewal system message on MPn+1, and correspondingly, terminal is when entering MPn+1, it is necessary to first receives the system message that network side updates, just can be updated afterwards, can cause certain renewal time delay. Scheme 2 is paging scheme, namely UE receives beep-page message to obtain system information change notification, after UE receives notice, it is possible to the update method adopting LTE version 8/9 the same receives system information, equally, network side is renewal system message on MPn+1, correspondingly, terminal is when entering MPn+1, it is necessary to first receive the system message that network side updates, just can be updated afterwards, certain renewal time delay can be caused.

Detailed description of the invention

The invention provides a kind of system information update method and device, it is applied to multicarrier system, described multicarrier system has multiple downlink component carrier (CC), terminal is configured with one or more described CC, terminal is with a CC of its configuration for principal component carrier wave (PCC), and remaining CC is from component carrier (SCC). Its basic conception is: on the basis of R8/R9 handling process, namely, network side is when the system information initiating one or more CC updates, beep-page message is sent to terminal in notice interval (MPn), issue the system message of renewal in renewal interval (MPn+1) to terminal, terminal after receiving the paging message, receives the system message of renewal in renewal interval (MPn+1), and on the scheme basis updated according to this, give following prioritization scheme:

Correspondingly, described terminal is after receiving to update the beep-page message of system message, one or more CC of its configuration attempts receiving the temporary system message of the system message being packaged with renewal, if able to receive described temporary system message, then preserve described temporary system message and update interval (MPn+1) and activate described temporary system message entering and be updated; If described temporary system message can not be received, then in MPn+1, receive the system message of the renewal that network side issues in MPn+1, and update according to this.

Therefore, adopting above-mentioned prioritization scheme, terminal can complete the reception of the system message updated in MPn, can activate immediately at entrance MPn+1 and perform renewal, thus improve the processing speed of renewal.

It is described in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, the figure shows embodiment of the present invention one system information update method flow chart, comprise the steps:

Step S101: in MPn, eNB is to being configured with the terminal transmission beep-page message needing to update the CC of system message, described beep-page message comprises systemInfoModification and/or evolution-universal terrestrial wireless access network Absolute Radio Frequency Channel number (E-UTRAabsoluteradiofrequencychannelnumber, it is called for short EARFCN) list, described systemInfoModification is in order to indicate PCC generation systems information updating, and described EARFCN list is in order to indicate the SCC generation systems information updating corresponding for EARFCN in described EARFCN list;

In embodiments of the present invention, the beep-page message in R8/R9 is improved, including:

(1) update mode reinterpreting to coordinate the present invention of the systemInfoModification in the beep-page message of R8/R9 is selected function. Specifically, the systemInfoModification comprised in described beep-page message can have 2 values, respectively in order to indicate terminal to adopt following 2 kinds of PCC system information update modes to be: instruction terminal receives the system message of renewal that network side issues in MPn+1, and update according to this, namely adopt R8/R9 update scheme; And instruction terminal receives the temporary system message that network side issues in MPn, and update according to this.

(2) list of the EARFCN of the component carrier that increase is changed in order to indicating system message.

Further, described beep-page message can also increase a systemInfoModification list, the systemInfoModification comprised in described systemInfoModification list and the EARFCN one_to_one corresponding in described EARFCN list, described systemInfoModification has 2 values, respectively in order to indicate the SCC system information update mode of the EARFCN of its correspondence to be: instruction terminal receives the system message of the renewal that network side issues in MPn+1, and updates according to this; Instruction terminal receives the temporary system message that network side issues in MPn, and updates according to this.

Further, in order to reduce UE power consumption, UE only monitors beep-page message on PCC, and does not monitor beep-page message on SCC. For this, network side is when sending beep-page message to the UE being configured with described downlink component carrier, if described downlink component carrier is the SCC of a UE, then network side sends beep-page message to described UE on the PCC of described UE, thus enhancing paging, it is ensured that terminal can know there is system update on SCC. For eNB, when eNB sends beep-page message on the respective PCC of UE, it is possible to so determine the CC needing to send beep-page message: step 1: determine that carrier system information changes the UE affected; Step 2: determine the respective PCC of all UE; Step 3: determining that the beep-page message sent on each CC should notify which carrier wave generation systems message changes, the CC namely changed using this carrier wave as the system message involved by the UE of PCC, therefore for some UE, the system message of some CC is unwanted.

For example, with reference to Fig. 2, if CC1 and CC4 generation systems information changes, step 1: relevant UE is UE1, UE2, UE3, UE4 and UE5, the PCC of step 2:UE1 is the PCC that PCC is CC2, UE3 of CC1, UE2 is CC4, the PCC of UE4 is CC5, the PCC of UE5 is CC5, and step 3:CC1 sends the temporary system message of CC1, the upper temporary system message sending CC4 of CC2, the upper temporary system message sending CC1 and CC4 of CC4, the upper temporary system message sending CC1 and CC4 of CC5.

Step S102: in MPn, eNB is intended to be encapsulated as one or more temporary system message in the system message updating each renewal being handed down to terminal in interval (MPn+1), and is sending described temporary system message on one or more CC that described terminal configures after sending beep-page message to described terminal;

Such as, UE is configured with CC1, CC2, CC3, wherein CC1 and CC2 needs to carry out system message update, then eNB can in MPn, respectively the system message that CC1 updates is encapsulated as temporary system message 1, the system message that CC2 updates is encapsulated as temporary system message 2, then will one or more in CC1, CC2, CC3 of temporary system message 1 and temporary system message 2 send. Or, can also be, eNB can in MPn, the system message, the system message of CC2 renewal that are updated by CC1 are encapsulated in a temporary system message, are packaged with the temporary system message of the system message of the CC1 system message updated and CC2 renewal described in then sending on one or more in CC1, CC2, CC3.

Described temporary system message at least includes MIB, SIB1 and SIB2. Certainly, according to actual needs, described temporary system message can also encapsulate other chunk, for instance, when receiving MBMS, it is also possible to by SIB13 encapsulation to described temporary system message.

The handling process of temporary system message is as shown in Figure 3: the RRC (Radioresourcecontrol of eNB, wireless heterogeneous networks) system information issuing UE will be needed to be merged into T-SIB (temporarysysteminformationblock, temporary system message blocks) after, successively submit downwards, through RLC (radiolinkcontrol, wireless spread-spectrum technology) layer, process as TMRLCPDU (transparentmoderadiolinkcontrolprotocoldataunit, transparent mode radio link control protocol data cell), through MAC (mediaaccesscontrol, medium education) layer is treated as MACPDU (mediaaccesscontrolprotocoldataunit, media access control protocol data unit), it is TB (transportblock through physical layer process, transmission block). afterwards, PDCCH (PhysicalDownlinkControlChannel, Physical Downlink Control Channel) and PDSCH (PhysicalDownlinkSharedChannel, Physical Downlink Shared Channel) is used to send packaged TB.

ENB selects the operation time (activetime) at UE to send this system message, it is preferred that, it is possible to select the operation time of most of UE to send this system message, and repeat to send;

Packaged described temporary system message uses PDCCH (PhysicalDownlinkControlChannel, Physical Downlink Control Channel) and PDSCH (PhysicalDownlinkSharedChannel, Physical Downlink Shared Channel) when sending, scrambling can also be carried out, to reduce co-channel interference, improve timing accuracy.

Wherein, CRC (the CyclicRedundancyCheck of PDCCH, cyclic redundancy check) Temporary-SI-RNTI (temporary system information RNTI) can be used to carry out scrambling, PDSCH can use SI-RNTI (system information RNTI) or Temporary-SI-RNTI (RadioNetworkTemporaryIdentifier, Radio Network Temporary Identifier) to carry out scrambling.

Correspondingly, UE is after receiving described temporary system message, if the described scrambled process of temporary system message, then UE also needs to it is carried out scramble process, including obtaining Temporary-SI-RNTI, and carries out scramble process according to this.

UE can obtain Temporary-SI-RNTI with the following methods:

Mode (1): UE only configures a Temporary-SI-RNTI, this Temporary-SI-RNTI is configured by systeminformation, such as can increasing temporary-SI-RNTI field in SIB2, its value can take other values being different from SI-RNTI and non-zero 000 in 3GPP standard document 36.321.910 in form 7.1-1. Or set up when RRC connects by RRC signal deployment by UE, can configuration signal being such as the RRCConnectionReconfiguration signaling of 3GPP standard document 36.331.900, its value takes other values being different from SI-RNTI and non-zero 000 in 3GPP standard document 36.321.910 in form 7.1-1. Or can also be directly written in specification, for instance its value can take the FFF4-FFFC of the reservedforfuture in 3GPP standard document 36.321.910 specified by form 7.1-1.

Mode (2): each CC configures a CC-SI-RNTI (component carrier-system information-RNTI), this CC-SI-RNTI is configured by systeminformation, such as can increasing CC-SI-RNTI field in SIB2, its value can take other values being different from SI-RNTI and non-zero 000 in 3GPP standard document 36.321.910 in form 7.1-1. Or set up when RRC connects by RRC signal deployment by UE, such as, configuration signal is the RRCConnectionReconfiguration signaling of 3GPP standard document 36.331.900, its value takes other values being different from SI-RNTI and non-zero 000 in 3GPP standard document 36.321.910 in form 7.1-1, Temporary-SI-RNTI can take any of value, take the CC-SI-RNTI of which correspondence, just illustrate to send T-SIB on which CC.

Step S103: terminal receives and judges described beep-page message, if described beep-page message comprises systemInfoModification, on the PCC of its configuration, then attempt receiving the temporary system message of the system message being packaged with renewal, if it is determined that described beep-page message comprises EARFCN list, then on one or more CC of its configuration, attempt receiving the temporary system message of the system message being packaged with renewal;

The embodiment of the present invention for 2 kinds of paging ways, illustrates the system message update process of end side at this:

Beep-page message form 1: on this beep-page message beep-page message basis in R8/R9, systemInfoModification is redefined, if it is true, then instruction terminal adopts temporary system information updating PCC, if it is false, then instruction terminal adopts the update mode of R8/R9 to update PCC, the EARFCN list of the newly-increased SCC in order to indicate generation systems information updating.

ENB sends on the PCC of each UE in MPn and strengthens the relevant UE of beep-page message notice, and relevant UE refers to the UE that system message changes, and then starts to change system information from MPn+1.

Terminal is as follows to the processing procedure of the beep-page message of form 1:

Process 1:LTE-A enhancing UE judges whether this beep-page message exists SystemInfoModification after receiving beep-page message, if existed, so illustrate that this PCC needs to carry out system information renewal, if this SystemInfoModification is true, so first in MPn, receive temporary system information, and according to temporary system information reception condition, receive at MPn+1 and normally update system information, if this SystemInfoModification is false, then UE receives normal system information according to the update mode of R8/R9.

Process 2:LTE-A strengthens UE and then judges whether to include in beep-page message EARFCN list, if including, the SCC generation systems information updating corresponding for each EARFCN in this EARFCN table is described, so first in MPn, receive temporary system information, and according to temporary system information reception condition, receive at MPn+1 and normally update system information.

Beep-page message mode 2: systemInfoModification is redefined on the beep-page message basis in R8/R9 by this beep-page message, if it is true, then instruction terminal adopts temporary system information updating PCC, if it is false, then instruction terminal adopts the update mode of R8/R9 to update the systemInfoModification list of PCC, EARFCN list and correspondence thereof.

Terminal is as follows to the processing procedure of the beep-page message of form 2:

Process 1:UE judges whether this beep-page message includes systemInfoModification after receiving beep-page message on its PCC, if including, so illustrate that this PCC needs to carry out system information renewal, determine whether, if this SystemInfoModification is true, so first in MPn, receive temporary system information, and according to temporary system information reception condition, normal system information is received at MPn+1, if this SystemInfoModification is false, then UE receives normal system information according to the update mode of R8/R9 at MPn+1. If beep-page message does not include systemInfoModification, then UE receives normal system information according to the update mode of R8/R9 at MPn+1.

Process 2:UE then judges the SystemInfoModification list whether including EARFCN and correspondence thereof in beep-page message, if including, SCC generation systems information updating corresponding for this EARFCN is described, to each UE EARFCN configured, if SystemInfoModification corresponding for this EARFCN is true, so first receiving temporary system information in MPn, UE can receive relevant temporary system message on the CC of any activation respectively; UE, according to temporary system information reception condition, receives normal system information at MPn+1; If SystemInfoModification corresponding for this EARFCN is false, then UE receives normal system information according to the update mode of R8/R9 at MPn+1. UE ignores the temporary system message corresponding to not configuring CC received.

Step S104:UE judges whether it is successfully received described temporary system message in MPn, if, UE receives described temporary system message in MPn and preserves, and activates the temporary system information preserved when entering MPn+1, and the system information to complete UE side updates; Otherwise, UE adopts traditional paging (paging) update method used by R8/R9, receives system message in MPn+1, then performs system information and updates.

UE in the present embodiment refers to be configured with and receives temporary system message function and open the UE of this function.

Illustrate with an application example below, it is assumed that eNB sends beep-page message notice at MPn and configures all UE of this CC, then starts to update the system information of multiple CC from MPn+1, with continued reference to Fig. 2: assume that all CC activate. UE1 monitors and receives the beep-page message on CC1, and this beep-page message instruction CC1 generation systems message changes, and UE1 will receive the temporary system message of CC1 on CC1 or CC2. UE2 monitors and receives the beep-page message on CC2, and this beep-page message instruction CC4 generation systems information changes, and UE1 will receive the temporary system message of CC4 on CC2 or CC4. UE3 monitors and receives the beep-page message on CC4, and this beep-page message instruction CC1 and CC4 generation systems information changes, and UE3 will receive the temporary system message of CC1 and CC4 on CC1, CC4 or CC3.
