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 enhancement techniques, 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 enhancement techniques of introducing, yet the system information content of LTE (Long Term Evolution) system is not enough to support these new features of evolution systems such as LTE-A at present, for example for the carrier aggregation characteristic among the LTE-A, a plurality of carrier waves are formed a LTE-A sub-district.But which carrier wave is the system information of using LTE at present can't indicate belong to same LTE-A sub-district, so just makes UE can't know that whether network supports the characteristic of LTE-A etc., also just can't apply for obtaining the service that LTE-A could support.Therefore UE need know which carrier wave is arranged in the LTE-A sub-district, 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:
The LTE system uses paging to trigger called service and notice UE system information is about to change.Beep-page message is dispatched by PI-RNTI.RRC-IDLE UE in the network decoded to the PDCCH channel in the specific moment, obtained 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, as the change of ETWS.Under the situation of not receiving system information change indication, UE need read beep-page message modificationPeriodCoeff time at least in the next one is revised the cycle, in the hope of 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 the frequent read system information of UE, thereby reduces the power consumption of UE.
In addition, evolution systems such as LTE-A also need compatible existing LTE system, make the UE of LTE system also can be operated in the evolution systems such as LTE-A system., in the LTE-A system, need expand, with the new features of evolution systems such as support LTE-A system the system information in the LTE 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 SIB 12, SIB 13 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 to LTE is not optimized, then in the LTE-A system, the beep-page message that comprises system information change indication is except indication LTE system original system change in information, the IE and/or the new SIB 12 that introduces that also need indicate the LTE-A system in original SIB, to expand, the variation of SIB 13......, but these UE that change to LTE are sightless.For example, suppose that SIB 12 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 being preserved is not up-to-date, triggers read system information again.But this moment, visible all system informations of LTE UE all do not change in fact, only are that the SIB 12 of the LTE-A system that increases newly 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 taken place 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 being preserved is not up-to-date, thereby triggers read system information again.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.
Summary of the invention

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