  • Publication number: 20140126527
    Abstract: A small cell receives a dedicated synchronization signal Preamble sent through a first message by a user equipment UE in an idle state. The dedicated Preamble is allocated when the UE accesses a network for the first time. The small cell according to the dedicated Preamble queries whether a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE are/is stored. If stored, the small cell replies in a second message to the UE that indication information that the SRB 1 and/or the SRB2 between the small cell and the UE do/does not need to be re-established or modified. An uplink radio resource control RRC message sent through a dedicated control channel DCCH by the UE is received.

  • Patent number: 8615242
    Abstract: Embodiments of the present invention provide a method and a user equipment for cell selection of a heterogeneous network. The UE selects, a cell with a highest signal measurement value in a carrier frequency synchronizes to the cell, and receives broadcast information of the cell. If the cell is a macro cell, the broadcast information carries an extended indicator bit and the extended indicator bit is used to identify whether a low-power cell exists in the coverage of the macro cell. If the extended indicator bit identifies that the low-power cell exists in the coverage of the macro cell, the low-power cell in the macro cell is searched for, and if a low-power cell in the macro cell satisfies an S rule, the UE selects the lower-power cell as a serving cell and camps.
