Embodiment 1
[0116] In the LTE system, the core network control node is the MME. Since the MME is connected to the LGW through the SGW, the interface between the SGW and the LGW, that is, the user plane interface between the LGW and the core network is the S5 interface.
[0117] The terminal device activates LIPA in the cell of the home base station, and then the target cell is switched to the macro cell due to the movement of the terminal.
[0118] like Figure 7 As shown, it is a schematic flowchart of a data transmission method in a specific scenario proposed in Embodiment 1 of the present invention, which specifically includes the following steps:
[0119] Step S701 , due to the movement of the UE, the source HNB initiates an S1 handover process, and performs corresponding processing according to the procedure specified in TS 23.401 (specifically, steps 1 to 15).
[0120] Step S702, the MME sends a Change Notification Request message to the SGW, which carries indication information in...
Embodiment 2
[0127] In the UMTS system, the core network control node is the SGSN, and the user plane interface between the SGSN and the LGW is the Gn interface.
[0128] The terminal activates LIPA in the cell of the home base station, then enters the idle state and resides in the macro cell, and then the LGW receives downlink data.
[0129] like Figure 8 As shown, it is a schematic flowchart of a data transmission method in a specific scenario proposed in Embodiment 2 of the present invention, which specifically includes the following steps:
[0130] In step S801, the LGW receives downlink data that needs to be sent to the UE.
[0131] Step S802, the LGW sends the first data packet of the downlink data to the SGSN, and buffers other data packets.
[0132] Step S803, the SGSN pages the UE within a certain area.
[0133] Step S804, the UE responds to the paging of the SGSN, and accesses the network through the macro base station (RNC).
[0134] The SGSN judges that the UE accesses thr...
Embodiment 3
[0140] The application scenario of this embodiment is that in an LTE system, the core network control node is an MME.
[0141] The terminal activates LIPA in the cell of the home base station, then enters the idle state and resides in the macro cell, and then the LGW receives downlink data.
[0142] like Figure 9 As shown, it is a schematic flowchart of a data transmission method in a specific scenario proposed in Embodiment 3 of the present invention, which specifically includes the following steps:
[0143] In step S901, the LGW receives downlink data that needs to be sent to the UE.
[0144] Step S902, the LGW sends the first data packet of the downlink data to the SGW, and buffers other data packets.
[0145] Step S903, the SGW sends a downlink data notification to the MME.
[0146] Step S904, the MME pages the UE within a certain area.
[0147] Step S905, the UE responds to the paging of the MME, and accesses the network through the macro base station (eNB).
