Abstract
The invention discloses a method and a device for processing system messages of component carriers to be acquired. The method comprises the following step that: when user equipment (UE) needs to read system messages of other component carriers except for the component carrier served by the UE, a network indicates the carrier types of other component carriers of the UE by system message broadcasting or special signaling, so that the UE processes the system messages of other component carriers according to the carrier types. By the method and the device, the problem that the failure of UE in acquiring the system messages of the component carriers in a long term evolution-advance (LTE-A) system may lead to behavior inconsistency between the network and user equipment is solved, and the UE can dispatch reasonably on all component carriers of a cell.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of processing method and the device that do not get the system message of component carrier.
Background technology
In Long Term Evolution (Long Term Evolution, referred to as LTE) system, terminal UE, after idle condition selects a community, reads the system message that community is broadcasted.When UE obtains Master Information Block (Master Information Block, referred to as the MIB)/SIB1/SIB2 system message failure of community, just think that this community is barred (being prevented from), UE carries out cell reselection.
At senior Long Term Evolution (Long Term Evolution-Advance, referred to as LTE-A) system, LTE-A UE is in idle condition, selection is only needed to reside on one-component carrier wave, so also only need the system message (resident component carrier is its service component carrier wave) reading resident component carrier, so UE obtains identical with the LTE stage with the behavior on system message update in system message.
But for the LTE-A UE of connection status, in order to improve the transmission rate of up-downgoing, the up-downgoing of UE can configure and use multiple component carrier (Component Carrier, referred to as CC).The component carrier type of current definition has 3 kinds: backward compatibility component carrier, non-backward compatible component carrier and expansion component carrier.Backward compatibility component carrier be LTE UE and LTE-A UE can resident and use component carrier; Non-backward compatible component carrier be can only LTE-A UE resident and use component carrier; Expansion component carrier is can only the component carrier that uses in connection status of LTE-A UE, and this component carrier can not independently be used by LTE-A UE, and needs use together with other two kinds of component carriers.
Because backward compatibility component carrier and non-backward compatible component carrier can be resident by UE, so carrier wave necessarily all can have the system messages such as MIB/SIB1/SIB2; Current related protocol does not also determine whether expansion carrier wave carries system message.Because expansion carrier wave can not independently exist, some contents in its system information should be identical with other component carrier, thus have a kind of viewpoint think expansion component carrier on do not need to carry system message.For system information specific on expansion carrier wave, UE can be notified by network side by dedicated signaling.
When LTE-A UE enters connection status from idle condition, in order to UE can be used except its other component carrier except the component carrier of idle condition service, just need to allow UE obtain system information on other component carrier.So when broadcast on other component carrier has system message, UE needs to go to read the system message on these component carriers.
If in other component carrier be backward compatibility component carrier or non-backward compatible component carrier, LTE-A UE has the system message successfully do not read on other component carrier, and network side is not also known.In addition, if in other component carrier be expansion carrier wave, because expansion component carrier does not have carrying system message, so the system message acquisition behavior on expansion component carrier is different with backward compatibility component carrier or non-backward compatible component carrier.
Do not get the inconsistent problem of network that component carrier system message may cause and terminal behavior for UE in lte-a system in correlation technique, not yet propose effective solution at present.
