[0095] In the LTE Advance system, the schematic diagram of its network layout can be found in figure 2 , there is an S1 interface between the core network and the base station (macro base station), and there is an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or can be connected to the core network through the home base station gateway. There is no X2 interface between the home base station and the macro base station. The UE is located in a carrier aggregation cell under the jurisdiction of the macro base station (or home base station), and is in an idle state. The component carriers included in the carrier aggregation cell are three consecutive 20MHz component carriers within the frequency band 1 (Band 1, uplink UL 1920-1980MHz, downlink DL 2110-2170MHz). These three carriers all send system messages and paging messages.

[0104] In the LTE Advance system, the schematic diagram of its network layout can be found in figure 2 , there is an S1 interface between the core network and the base station (macro base station), and there is an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or can be connected to the core network through the home base station gateway. There is no X2 interface between the home base station and the macro base station. The UE is located in a carrier aggregation cell managed by the home base station and is in a connected state. The carrier aggregation cell contains component carriers in frequency band 1 (Band 1, UL 1920~1980MHz, DL 2110~2170MHz) and frequency band 2 (Band 2, UL 1850~1870MHz, DL 1930~1950). A discontinuous 20MHz component carrier. Among the four carriers, only three component carriers in Band 1 send system messages and paging messages.
