Description
Technical field
The present invention relates to communication technical field, particularly a kind of method, system and device of system information.
Background technology
At Long Term Evolution wide-band mobile communication system (LTE-Advanced, LTE-A) in, introduced a series of enhancing technology, such as via node (RN, Relay Node), multi-point cooperative transmission (COMP, Coordinated Multiple Point transmission and reception) and carrier aggregation (CA, Carrier Aggregation) etc.The information that therefore in the system information of LTE-A, also should comprise these enhancing technology of introducing, yet LTE (Long Term Evolution) the system of systems information content is not enough to support these new features of the evolution systems such as LTE-A at present, for example for the carrier aggregation characteristic among the LTE-A, a plurality of carrier waves form a LTE-A residential quarter.But which carrier wave is the system information of using at present LTE can't indicate belong to same LTE-A residential quarter, so just whether supports the characteristic of LTE-A etc. so that UE can't be known network, also just can't apply for obtaining the service that LTE-A could support.Therefore UE need to know which carrier wave is arranged in the LTE-A residential quarter, and whether these carrier waves can polymerizations, and these carrier bandwidths and band information are so that apply for suitable service.
In the LTE system, the main contents that system information sends are mainly as shown in the table:
| Host system message block (MIB) | Major parameter has: downlink bandwidth, the configuration information of PHICH, System Frame Number (SFN) |
| System information block 1 (SIB1) | Main contents have: the information (PLMN ID, TAC, cell ID etc.) relevant with the residential quarter access, select relevant parameter with the residential quarter, maximum transmission power, band information, the schedule information of system information, the TDD configuration parameter, SI length of window, systemInfoValueTag etc. |
| System information block 2 (SIB2) | Main contents comprise: access barred information, wireless resource configuration, terminal timer and some constant information, frequency information, MBSFN subframe configuration information, the information of synchro timer etc. |
| System information block 3 (SIB3) | Main contents have: the common parameter of cell reselection, the cell reselection parameters of service frequency, the information such as relevant parameter of co-frequency cell gravity treatment. |
| System information block 4 (SIB4) | Main contents have: co-frequency cell tabulation, with blacklist cell list frequently, the Physical Cell Identifier of CSG residential quarter with and scope. |
| System information block 5 (SIB5) | Main contents have: the alien frequencies carrier information is tabulated, and comprises the frequency of each carrier wave, reselecting parameters, precedence information, iso-frequency adjacent community information, blacklist etc. |
| System information block 6 (SIB6) | Main contents comprise for being used for the relevant information to the gravity treatment of UTRA system cell: the relevant information of UTRA system can comprise the tabulation of UTRA FDD carrier information, the tabulation of UTRA TDD carrier information, reselecting parameters etc. |

The LTE system triggers called service with paging and notice UE system information is about to change.Beep-page message is dispatched by PI-RNTI.RRC-IDLE UE in the network decodes to the PDCCH channel specific constantly, obtains beep-page message.When network needs altering system information, at first use beep-page message to the UE transmitting system information-change indication (System Info Modification) that is in RRC-IDLE and RRC-Connected state, if UE has received the beep-page message that comprises system information change indication, just know that system information will change.System information change indication only can notify the UE system information to change, and can not indicate which or which system information to change.In addition, the change of some system information can not trigger the transmission of the beep-page message that comprises system information change indication, such as the change of ETWS.In the situation that do not receive system information change indication, UE need to read beep-page message modificationPeriodCoeff time at least in the next one is revised the cycle, to finding system information change indication.If UE reads the beep-page message that comprises system information change indication, just think that system information will change.Introducing by system information change indication can be avoided frequently read system information of UE, thereby reduces the power consumption of UE.
In addition, the evolution systems such as LTE-A also need compatible existing LTE system, so that the UE of LTE system also can be operated in the evolution systems such as LTE-A system., in the LTE-A system, need to expand the system information in the LTE system, with the new features of the evolution systems such as support LTE-A system for this reason.Carry out the system information expansion and can have following dual mode:
One, add new IE (information unit) in existing SIB, the new IE that introduces is sightless for LTE UE, and is visible for LTE-A UE.
Two, introduce new SIB, as introducing SIB12, SIB13 etc., the new SIB that introduces is sightless for LTEUE, and is visible for LTE-A UE.
Therefore, the compatible LTE of LTE-A needs system.If the system information Notification of Changes scheme of LTE is not optimized, then in the LTE-A system, comprise the beep-page message of system information change indication except the variation of indication LTE system original system information, IE and/or the new SIB12 that introduces that also need indicate the LTE-A system in original SIB, to expand, SIB13...... variation, but these UE that change to LTE are sightless.For example, suppose that SIB12 changes, cause the base station to send and comprise the beep-page message that the system information change is indicated.LTE UE receives and comprises system information change indication, just knows that own system information of preserving is not up-to-date, triggers again read system information.But this moment, visible all system informations of LTE UE all do not change in fact, only are that the SIB12 of the LTE-A system that newly increases changes, and therefore this time system information is read again and be there is no need, and causes the waste of UE power consumption.Perhaps, suppose the SIB2 in the LTE system is expanded, introduced new IE.If variation has occured in the new IE that introduces of SIB2 this moment, cause the base station to send and comprise the beep-page message that the system information change is indicated, then LTE UE receives system information change indication, knows that own system information of preserving is not up-to-date, thereby triggers again read system information.But this moment, its visible all system informations did not all change for LTE UE, and therefore this time system information is stressed there is no need, and also can cause the waste of UE power consumption.

Wherein, in one embodiment of the invention, the first system information-change indication in the beep-page message is used to indicate the situation of change of the SIB relevant with system information in the LTE system.Second system information-change indication in the beep-page message is used to indicate the situation of change of the SIB relevant with new drawing-in system information in the LTE-A system.Only need to again read the part SIB that changes for LTE-A UE like this gets final product, if i.e. the first system information-change indication changes, then directly reading the part SIB relevant with the indication of the first system information-change gets final product, if the indication of second system information-change changes, then directly reading the part SIB relevant with the indication of second system information-change gets final product, so also can effectively reduce the number of times that LTE-A UE repeats to read, save power consumption.And for LTE UE, it is concerned about the situation of change of the first system information-change indication, only it just understands read system information when the indication of the first system information-change changes, and so also can reduce the number of times that LTE UE repeats to read, and reaches the purpose of saving power consumption.
Yet in this embodiment, the information unit IE that also may include the LTE-A system among the SIB that system information is relevant in the LTE system, if namely the LTE-A system adopts the mode that the new IE of introducing expands in existing SIB, if and the IE of just this new introducing that changes, then this first system information-change indication also can change, and the new IE that introduces is unreadable for LTE UE, thereby causes LTE UE to carry out unnecessary again reading.
Therefore, in another embodiment of the present invention, different from above-described embodiment is that in this embodiment the first system information-change indication is used to indicate the situation of change of the IE relevant with system information in the LTE system.Same second system information-change indication is used to indicate the situation of change of new drawing-in system information in the LTE-A system, the SIB that namely newly introduces or the new IE that introduces in original SIB.Like this, the indication of the first system information-change is indicated the situation of change of the IE relevant with system information in the LTE system, thereby is avoided the LTE UE that causes that occurs occurring in above-described embodiment to carry out unnecessary situation about again reading among this embodiment.
Scheme two is expanded dispatch id.
In this scheme, the first change indication and the second change are designated as the first dispatch id (such as PI-RNTI1) that the base station is the first beep-page message of dispatching of UE and second dispatch id (such as PI-RNTI2) of the second beep-page message.Wherein, in this scheme, also can expand in a different manner, as:
Mode one,
In the LTE system, use the transmission of the first dispatch id notice UE beep-page message.In the LTE-A system, dispatch id is expanded, increase by the second dispatch id, with the second system information-change indication of the second dispatch id scheduling be used to indicate with the LTE-A system in new drawing-in system information associated change situation.
Wherein, in one embodiment of the invention, the first system information-change indication of the first dispatch id scheduling is used to indicate the situation of change of the SIB relevant with system information in the LTE system.The second system information-change indication of the second dispatch id scheduling is used to indicate the situation of change of the SIB relevant with new drawing-in system information in the LTE-A system.Only need to again read the part SIB that changes for LTE-A UE like this gets final product, if i.e. the first system information-change indication changes, then directly reading the part SIB relevant with the indication of the first system information-change gets final product, if the indication of second system information-change changes, then directly reading the part SIB relevant with the indication of second system information-change gets final product, so also can effectively reduce the number of times that LTE-A UE repeats to read, save power consumption.And for LTE UE, it is concerned about the situation of change of the first system information-change indication, only it just understands read system information when the indication of the first system information-change changes, and so also can reduce the number of times that LTE UE repeats to read, and reaches the purpose of saving power consumption.
Yet in this embodiment, the information unit IE that also may include the LTE-A system among the SIB that system information is relevant in the LTE system, if namely the LTE-A system adopts the mode that the new IE of introducing expands in existing SIB, if and the IE of just this new introducing that changes, then this first system information-change indication also can change, and the new IE that introduces is unreadable for LTE UE, thereby causes LTE UE to carry out unnecessary again reading.
Therefore, in another embodiment of the present invention, different from above-described embodiment is that in this embodiment the first system information-change indication is used to indicate the situation of change of the IE relevant with system information in the LTE system.Same second system information-change indication is used to indicate the situation of change of new drawing-in system information in the LTE-A system, the SIB that namely newly introduces or the new IE that introduces in original SIB.Like this, system information change indication among this embodiment in the first beep-page message of the first dispatch id scheduling, indicate the situation of change of the IE relevant with system information in the LTE system, thereby avoid the LTE UE that causes that occurs occurring in above-described embodiment to carry out unnecessary situation about again reading.
Mode two,
System information change indication in the first beep-page message of the first dispatch id scheduling is used to indicate system information situation of change in the LTE system, the second dispatch id is used to indicate new drawing-in system information change situation in the LTE-A system, if UE finds the dispatch that dispatch id is the second dispatch id at PDCCH, illustrate that then new drawing-in system information changes in the LTE-A system.
Particularly, same, the situation of change that the first system information-change indication of the first dispatch id scheduling can be used for indicating the SIB relevant with system information in the LTE system.The dispatch that is scheduling to the second dispatch id on the PDDCH is used to indicate the situation of change of new drawing-in system information in the LTE-A system, and this dispatch is not dispatched any data.Only need to again read the part SIB that changes for LTE-A UE like this gets final product, if i.e. the first system information-change indication changes, then directly reading the part SIB relevant with the indication of the first system information-change gets final product, if the dispatch of the second dispatch id changes, then directly reading the part SIB relevant with the dispatch of the second dispatch id gets final product, so also can effectively reduce the number of times that LTE-A UE repeats to read, save power consumption.And for LTE UE, it is concerned about the situation of change of the first system information-change indication, only it just understands read system information when the indication of the first system information-change changes, and so also can reduce the number of times that LTE UE repeats to read, and reaches the purpose of saving power consumption.And the realization of this method is fairly simple.
Yet different from above-described embodiment is that the first system information-change indication of in this embodiment the first dispatch id scheduling is used to indicate the situation of change of the IE relevant with system information in the LTE system in another embodiment of the present invention.The dispatch of same the second dispatch id is used to indicate in the LTE-A system situation of change of new drawing-in system information, i.e. the new SIB that introduces and/or be the new IE that introduces in original SIB.Like this, the first system information-change indication of the first dispatch id scheduling among this embodiment, indicate the situation of change of the IE relevant with system information in the LTE system, thereby avoid the LTE UE that causes that occurs occurring in above-described embodiment to carry out unnecessary situation about again reading.
Step S102, UE is according to self-ability and the first change is indicated and/or the system information renewal is carried out in the second change indication.If UE is LTE UE, then UE only carries out the system information renewal when the first change indication indication mechanism information change; If UE is LTE-A UE, then UE carries out the system information renewal when the first change indication and/or the second change indication indication mechanism information change, only read the part system information that changes, if namely the first change indication indication mechanism information changes, then UE just reads the relevant system information of the first change indication; If the second change indication indication mechanism information changes, then UE just reads the relevant system information of the second change indication; If both change, then all read.Particularly, for example, suppose that the first change is designated as the variable of a 1bit, when this variable-value was 1, then UE need to read LTE system of systems information again; If value is 0, then needn't read again.
Need to prove that above-described embodiment evolves to LTE-A as example take LTE; but the application should not only limit in the LTE-A system; be applicable to too other have introduced new system information in evolution process communication system, so these other communication systems adopt method of the present invention also should be included within protection scope of the present invention.For example, evolve to second system from the first system, wherein the first system is the LTE-A system, and second system is the system of further evolution, and perhaps second system is the LTE system, and the first system is legacy system, etc. analogue.
