Abstract

The invention provides a method for updating system information, which is applied to a multi-carrier system. When a network side initiates system information update of one or more downlink component carriers (CC), the network side sends a paging message to a terminal in a notification interval (MPn), and issues an updated system message to the terminal in an updating interval (MPn+1), wherein the network side also packages each updated system message to be issued to the terminal in the MPn+1 into one or more temporary system messages in the MPn, and sends the temporary system messages on the one or more CCs configured by the terminal after sending the paging message to the terminal; and after receiving the paging message, the terminal tries to receive the temporary system messages on the one more CCs configured by the terminal; and if the temporary system messages are received, the terminal stores, activates and updates the temporary system messages when entering the MPn+1, otherwise, the terminal receives and updates the updated system message in the MPn+1.

Embodiment

The invention provides a kind of system information update method and device, be applied to multicarrier system, described multicarrier system has a plurality of downlink component carriers (CC), terminal configuration has one or more described CC, terminal is principal component carrier wave (PCC) with a CC of its configuration, and remaining CC is from component carrier (SCC).It is conceived substantially: on the basis of R8/R9 handling process, promptly, when network side upgrades in the system information of initiating one or more CC, between notification area, send beep-page message to terminal in (MPn), issue the system message of renewal between update area in (MPn+1) to terminal, terminal receives the system message of upgrading in (MPn+1) between update area after receiving beep-page message, and on the scheme basis of upgrading according to this, provided following prioritization scheme:

Correspondingly, described terminal is behind the beep-page message that receives in order to update system message, on one or more CC of its configuration, attempt receiving the temporary system message of the system message that is packaged with renewal, if can receive described temporary system message, then preserve described temporary system message and activate described temporary system message and upgrade entering between update area (MPn+1); If can not receive described temporary system message, the then system message of the renewal that the reception network side issues in MPn+1 in MPn+1, and renewal according to this.

Therefore, adopt above-mentioned prioritization scheme, terminal can be finished the reception of the system message of renewal in MPn, can activate immediately and carry out to upgrade entering MPn+1, thereby improve the processing speed of upgrading.

Be elaborated below in conjunction with accompanying drawing.

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

Step S101: in MPn, eNB sends beep-page message to the terminal that has disposed the CC that needs update system message, comprise the absolute wireless frequency channel number of systemInfoModification and/or evolution-unification land radio access web (E-UTRA absolute radio frequencychannel number in the described beep-page message, be called for short EARFCN) tabulation, described systemInfoModification is in order to the information updating of indication PCC generation systems, and described EARFCN tabulation is in order to indicate the SCC generation systems information updating of the EARFCN correspondence in the described EARFCN tabulation;

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

(1) reinterpreting the systemInfoModification in the beep-page message of R8/R9 to cooperate update mode selection function of the present invention.Specifically, the systemInfoModification that comprises in the described beep-page message can have 2 values, adopt following 2 kinds of PCC system information update modes to be in order to indicating terminal respectively: the system message of the renewal that indicating terminal reception network side issues in MPn+1, and upgrade according to this, promptly adopt the R8/R9 update scheme; And indicating terminal receives the temporary system message that network side issues in MPn, and upgrades according to this.

(2) increase is in order to the tabulation of the EARFCN of the component carrier of indicating system message change.

Further, can also increase systemInfoModification tabulation in the described beep-page message, the systemInfoModification that comprises in the described systemInfoModification tabulation is corresponding one by one with the EARFCN during described EARFCN tabulates, described systemInfoModification has 2 values, in order to the SCC system information update mode of indicating its corresponding EARFCN be respectively: the system message of the renewal that indicating terminal reception network side issues in MPn+1, and upgrade according to this; Indicating terminal receives the temporary system message that network side issues in MPn, and upgrades according to this.

Further, in order to reduce the UE power consumption, UE only monitors beep-page message on PCC, and does not monitor beep-page message on SCC.For this reason, network side is when the UE that has disposed described downlink component carrier sends beep-page message, 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, thereby strengthened paging, guaranteed that terminal can be known and have system update on the SCC.For eNB, when eNB sends beep-page message on UE PCC separately, can determine to need to send the CC of beep-page message like this: step 1: determine the UE that the carrier system information-change is influenced; Step 2: determine all UE PCC separately; Step 3: determine that each CC goes up the beep-page message that sends and should notify which carrier wave generation systems message change, promptly with the CC of this carrier wave as the related system message variation of the UE of PCC, therefore for some UE, the system message of some CC is unwanted.

For example, referring to Fig. 2, if CC1 and CC4 generation systems information-change, step 1: relevant UE is UE1, UE2, UE3, UE4 and UE5, the PCC of step 2:UE1 is CC1, and the PCC of UE2 is CC2, and the PCC of UE3 is CC4, the PCC of UE4 is CC5, the PCC of UE5 is CC5, and step 3:CC1 goes up the temporary system message that sends CC1, the temporary system message of the last transmission of CC2 CC4, the temporary system message of CC4 last transmission CC1 and CC4, the temporary system message of CC5 last transmission CC1 and CC4.

Step S102: in MPn, eNB will desire to be handed down in (MPn+1) terminal between update area each system message of upgrading is encapsulated as one or more temporary system message, and on one or more CC after described terminal sends beep-page message in described terminal configuration the described temporary system message of transmission;

For example, UE disposes CC1, CC2, CC3, wherein CC1 and CC2 need carry out system message update, then eNB can be in MPn, the system message that CC1 is upgraded is encapsulated as temporary system message 1 respectively, the system message that CC2 is upgraded is encapsulated as temporary system message 2, will send in CC1, CC2, CC3 one or more of temporary system message 1 and temporary system message 2 then.Perhaps, also can be, eNB can be in MPn, the system message of CC 1 renewal, the system message that CC2 upgrades are encapsulated in the temporary system message, send the described system message of CC1 renewal and the temporary system message of the system message that CC2 upgrades of being packaged with then on one or more in CC1, CC2, CC3.

At least comprise MIB, SIB1 and SIB2 in the described temporary system message.Certainly, according to actual needs, can also encapsulate other block of informations in the described temporary system message, for example, when receiving the MBMS business, SIB13 can also be packaged in the described temporary system message.

The handling process of temporary system message is as shown in Figure 3: the RRC of eNB (Radio resource control, Radio Resource control) system information of needs being issued UE is merged into T-SIB (temporary systeminformation block, the temporary system message blocks) after, successively submit downwards, through RLC (radio linkcontrol, Radio Link control) layer, be treated to TM RLC PDU (transparent mode radio linkcontrol protocol data unit, the transparent mode wireless link control protocol data cell), through MAC (media access control, the medium access control) layer is treated as MAC PDU (mediaaccess control protocol data unit, media access control protocol data unit), through physical layer process is TB (transport block, transmission block).Afterwards, use PDCCH (PhysicalDownlink Control Channel, Physical Downlink Control Channel) and PDSCH (Physical DownlinkShared Channel, Physical Downlink Shared Channel) to send packaged TB.

The work moment (active time) that eNB is chosen in UE sends this system message, preferably, can select the work of most of UE to send this system message constantly, and repeats to send;

Packaged described temporary system message is used PDCCH (Physical Downlink ControlChannel, Physical Downlink Control Channel) and PDSCH (Physical Downlink Shared Channel, when Physical Downlink Shared Channel) sending, can also carry out scrambling, to reduce co-channel interference, improve regularly accuracy.

Wherein, the CRC of PDCCH (Cyclic Redundancy Check, cyclic redundancy check) can use Temporary-SI-RNTI (temporary system information RNTI) to carry out scrambling, PDSCH can use SI-RNTI (system information RNTI) or Temporary-SI-RNTI (Radio Network TemporaryIdentifier, Radio Network Temporary Identifier) to carry out scrambling.

Correspondingly, UE is after receiving described temporary system message, if described temporary system message is handled through scrambling, then UE also needs it is carried out scramble process, comprises and obtains Temporary-SI-RNTI, and carry out scramble process according to this.

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

Mode (1): UE only disposes a Temporary-SI-RNTI, this Temporary-SI-RNTI is by system information configuration, for example can increase the temporary-SI-RNTI field in SIB2, its value can be got other values that are different from SI-RNTI and non-0000 among the 3GPP standard document 36.321.910 among the form 7.1-1.Dispose by the RRC signaling when perhaps setting up the RRC connection by UE, can configuration signal be the RRCConnectionReconfiguration signaling of 3GPP standard document 36.331.900 for example, its value be got other values that are different from SI-RNTI and non-0000 among the 3GPP standard document 36.321.910 among the form 7.1-1.Perhaps also can directly write in the standard, for example its value can be got the FFF4-FFFC of the specified reserved for future of form 7.1-1 among the 3GPP standard document 36.321.910.

Mode (2): CC-SI-RNTI of each CC configuration (component carrier-system information-RNTI), this CC-SI-RNTI is by system information configuration, for example can increase the CC-SI-RNTI field in SIB2, its value can be got other values that are different from SI-RNTI and non-0000 among the 3GPP standard document 36.321.910 among the form 7.1-1.Dispose by the RRC signaling when perhaps setting up the RRC connection by UE, for example, configuration signal is the RRCConnectionReconfiguration signaling of 3GPP standard document 36.331.900, its value is got other values that are different from SI-RNTI and non-0000 among the 3GPP standard document 36.321.910 among the form 7.1-1, Temporary-SI-RNTI can get wherein any one value, get the CC-SI-RNTI of which correspondence, just explanation sends T-SIB on which CC.

Step S103: the terminal reception is also judged described beep-page message, if comprise systemInfoModification in the described beep-page message, then on the PCC of its configuration, attempt receiving the temporary system message of the system message that is packaged with renewal, if judge to comprise the EARFCN tabulation in the described beep-page message, then on one or more CC of its configuration, attempt receiving the temporary system message of the system message that is packaged with renewal;

The embodiment of the invention is example at this in 2 kinds of paging modes, and the system message update process of end side is described:

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

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

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

After receiving beep-page message, process 1:LTE-A enhancing UE judges whether this beep-page message exists SystemInfoModification, if exist, illustrate that so this PCC need carry out system information and upgrade, if this SystemInfoModification is true, so at first in MPn, receive temporary system information, and according to the temporary system information reception condition, receive normal updating system information at MPn+1, if this SystemInfoModification is false, UE receives normal system information according to the update mode of R8/R9 so.

Process 2:LTE-A strengthens UE and then judges whether comprise the EARFCN tabulation in the beep-page message, if comprise then the SCC generation systems information updating of each the EARFCN correspondence in this EARFCN table be described, so at first in MPn, receive temporary system information, and, receive normal updating system information at MPn+1 according to the temporary system information reception condition.

Beep-page message mode 2: this beep-page message redefines systemInfoModification on the beep-page message basis in R8/R9, if it is true, then indicating terminal adopts temporary system information updating PCC, if it is false, then indicating terminal adopts the update mode of R8/R9 to upgrade PCC, EARFCN tabulation and corresponding systemInfoModification tabulation thereof.

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

Process 1:UE judges after receiving beep-page message on its PCC whether this beep-page message comprises systemInfoModification, if comprise, illustrate that so this PCC need carry out system information and upgrade, further judge, if this SystemInfoModification is true, so at first in MPn, receive temporary system information, and according to the temporary system information reception condition, receive normal system information at MPn+1, if this SystemInfoModification is false, UE receives normal system information according to the update mode of R8/R9 at MPn+1 so.If beep-page message does not comprise systemInfoModification, UE receives normal system information according to the update mode of R8/R9 at MPn+1 so.

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