Description
Technical field
The present invention relates to wireless communication field, relate in particular to Long Term Evolution (long-term evolution, LTE) method that a kind of indicating system message changes in the system, and be in subscriber equipment (UserEquipment under the connection status, UE) obtain the method for the system message after the variation, and corresponding the indicating system message device and the UE that change.
Background technology
System message comprises: the timer sum counter of UE, Public Land Mobile Nerwork (Public LandMobile Network; PLMN) identifier (ID), registration zone ID, cell selecting and gravity treatment parameters needed; The ID of sub-district, configuration of common channel information is measured control messages or the like.
In the prior art, system message adopt main message blocks (Main Information Block, MIB) and System information block (System Information Block, (BroadcastChannel BCH) sends mode SIB) by broadcast channel.
When system message changes, network side is by paging channel (PCH, paging channel) sends the UE that the beep-page message notice is in idle condition or cell paging channel (CELL_PCH) state, UE receives the main message blocks label value that reads behind the beep-page message wherein, if find that the label value of main message blocks is different with the main message blocks label value of its storage, then read broadcast channel (BCH), according to the label value of the System information block that comprises in the main message blocks, which System information block on the broadcast channel is read in decision.
For the UE that is in the CELL-FACH state, when system message changes, network side is by forward channel (Forward Access Channel, FACH) transmitting system message changes indication, UE receives the label value that reads main message blocks after this indication, if find that the label value of main message blocks is different with the label of the main message blocks of its storage, then read broadcast channel (BCH), determine according to the label value of the System information block that comprises in the main message blocks this reads which System information block on the broadcast channel.For the UE that is in cell private channel (CELL DCH) state, UE does not need to catch the system message of variation.
In the LTE system, UE has only two states: idle condition and connection status.When system message changes, for the UE of idle condition, can be by the network side distributing paging, UE goes to catch corresponding system message according to beep-page message then.
And under connection status, UE also has energy-saving mode, and promptly when the activity of UE bag was lower than certain rank, network side was just controlled UE and entered energy-saving mode.Under energy-saving mode, the discontinuous transceive data of UE that is to say that UE may accept a period of time data, and then sleep a period of time, and UE can not keep uplink synchronous in the length of one's sleep; When uplink loss, if UE will carry out up access again, just need catch some system parameterss about inserting, therefore, need capturing system message in this case, but in LTE, paging only is used for the UE under the idle condition, for the UE under the connection status, paging no longer is considered to needs.Therefore, in the prior art, for this UE that is under the connection status energy-saving mode, when system message alteration, network side sends Radio Resource control (Radio Resource Control, RRC) message notifying system message alteration, but when UE in sleep time, this RRC message can't send to UE immediately, can only get up by first buffer memory, when UE wakes up, the media access control layer of network side (Media Access Control, MAC) could send to UE to RRC message, the primitives interoperation of this process need interlayer makes that operation is very complicated.
