Description
Technical field
The present invention relates to moving communicating field, relate in particular to message acquisition method and terminal in a kind of carrier wave switched system.
Background technology
At senior Long Term Evolution (LTE-A, Long Term Evolution-Advance) stage, the LTE-A terminal is in idle condition, only need to select to reside on the carrier wave, also just only need read the system message of resident carrier wave, therefore, for the LTE-A terminal of idle condition, system message obtain with system message update on behavior identical with the LTE stage.And,, increasing process by carrier wave in order to improve the transmission rate of up-downgoing for the LTE-A terminal of connection status, the up-downgoing of terminal can be disposed and be used a plurality of component carriers (CC, Component Carrier).In carrier wave increase process, the base station increases system information necessary on the carrier wave by dedicated signaling notice terminal.
Terminal can use a plurality of component carriers simultaneously in connection status, in these a plurality of component carriers, select one as principal component carrier wave (PCC, Primary Component Carrier), other carrier waves are as auxilliary component carrier (SCC, Secondary Component Carrier).Since a plurality of carrier waves of terminal polymerization simultaneously, and system message broadcasting is all arranged on a plurality of descending carrier, and therefore when on each component carrier system message update being arranged, the LTE-A terminal need in time be obtained the system message of upgrading on the carrier wave.
Renewal to system message among the LTE is handled as shown in Figure 1, and system message only can just can be revised in specific radio frames usually, and the time period that system message can not be revised is called system message and revises the cycle.When the base station needs update system message, at first notify terminal to revise the cycle in next system message, system message can change, and just begins to send updated system messages in the described next system message modification cycle then.Among Fig. 1, the base station is revised cycle n in system message and is sent beep-page message, and notice terminal system message will be upgraded at cycle n+1; Revise cycle n+1 in system message, the system message that base station broadcast upgrades.
Because the LTE-A terminal can polymerization be used a plurality of carrier waves, so its behavior and LTE terminal of obtaining system message update on each carrier wave are different.For the processing that PCC goes up system message update, it is identical with R8 that the LTE-A terminal of connection status is obtained the behavior of updated system messages; And if the system message on the SCC is upgraded, then the base station is by the relevant system information of dedicated signaling notice terminal.
Generally speaking, the base station can select signal quality relatively preferably CC as the PCC of terminal, and because the variation of wireless environment, the PCC of terminal may revise, as being revised as example with descending (DL) PCC among Fig. 2, the descending polymerization of terminal CC0 and CC1, and CC0 is DL PCC; Because the variation of wireless environment, the signal quality of CC1 is better, and the base station is revised as CC1 by reconfiguration message by CC0 with the DL PCC of terminal use so.This reconfiguration message also can be called PCC and switch message.
In order user's face not to be restarted and to avoid initiating inserting at random, PCC among the LTE-A switches the reconfiguration message that can select by non-switching to be realized, and among the LTE system message that can not carry the sub-district, and reshuffle finish after, terminal can not go to read the system message on the sub-district yet, therefore, it is not clear and definite in the prior art how terminal to be obtained the behavior of the system message on the new PCC.Particularly consider, if in system message is revised cycle n, the CC1 that terminal is used is changed to PCC by the SCC reprovision, terminal may be missed the beep-page message that reads system message update on the CC1 in system message is revised cycle n so, thereby causes terminal and do not know that system message will upgrade at cycle n+1.
Summary of the invention
