Embodiment
In the embodiment of the present invention when user equipment (UE) needs to receive business in other component carrier or community, by cell reselection or handoff procedure, be linked in other component carrier described or community; UE receives described business in other component carrier described or community.
The embodiment of the present invention, UE is when passing through worked main plot or principal component carrier wave does not receive the business needing to receive, UE, by cell reselection or handoff procedure, is linked into other (the referring to that UE can be operated in the frequency of this component carrier of support) component carrier supported and receives the business needed; Be linked into after in other community or component carrier, UE retrieves the business description information in this community or component carrier; And the business description information retrieved is presented to user, and user therefrom selects interested business to receive, UE determines the community that business that these needs receive is corresponding or component carrier; UE to reside in the community or component carrier determined and receives the described business needing to receive.
UE is when determining the business having described needs to receive in other component carrier, UE passes through the process of cell reselection or switching, be linked in other component carrier described and receive, maybe can reside in this component carrier and receive, and without the need to carrying out cell reselection or switching again when principal component carrier channel is of poor quality by the time, avoid there is no required business in principal component carrier wave, and the channel quality of principal component carrier wave better time UE cannot receive business required in other component carrier all the time because cell reselection or switching cannot be carried out, this method makes UE work in multi-carrier systems better.Wherein, UE can receive multiple business according to different demand in different component carriers, and described business can be MBMS or unicast service, also can be the business of other type, for MBMS in the embodiment of the present invention.
For convenience of description, supplement the explanation of several noun in embodiments of the present invention, this explanation is applicable to the present invention.
Main plot (Primary Cell, be called for short Pcell), also principal component carrier wave is claimed: be operated in basic frequency, UE can carry out initial connection establishment process or initial connection reconstruction process on that frequency, or in handoff procedure, be indicated as the community (note: this definition is from 36.331 agreements of LTE R10 of main plot, the text is as follows, Primary Cell:the cell, operating on the primary frequency, in which the UEeither performs the initial connection establishment procedure or initiates theconnection re-establishment procedure, or the cell indicated as the primary cell inthe handover procedure.).
Auxiliary community (Primary Cell, be called for short Scell), also auxiliary component carrier is claimed: be operated in an auxiliary frequency, this auxiliary frequency is configured by a RRC connection, and the Radio Resource (note: this definition from 36.331 agreements of LTE R10 of this side frequency for providing some subsidiary, the text is as follows, SecondaryCell:a cell, operating on a secondary frequency, which may be configured once anRRC connection is established and which may be used to provide additional radioresources.).
Serving cell (Serving Cell): a Ge Zhuhuofu community.Do not configure CA(CarrierAggregation for one) UE or do not have the UE of CA ability only to only have a Serving cell and Pcell.For the UE of configuration CA, " Serving cell " is for representing the set (note: this definition is from 36.331 agreements of LTE R10 of one or more community be made up of Pcell and Scell, the text is as follows, Serving Cell:a primary or a secondary cell.For a UE not configured with Carrier Aggregation(CA) or not capable of CA there is only one serving cell comprising of theprimary cell.For an UE configured with CA the term'serving cells'is used todenote the set of one or more cells comprising of the primary cell and all secondarycells.).
So, for the UE of LTE R9 and version before, owing to not having CA ability, do not support multi-transceiver technology, this kind of UE can only access in one-component carrier wave in multi-carrier systems, and so this component carrier is called the principal component carrier wave (Pcell) of such UE.Wherein, in embodiments of the present invention, the corresponding community of one-component carrier wave, namely one-component carrier wave also can be called a community, and a corresponding one-component carrier wave in community, Ji Yige community also can be called one-component carrier wave.
