Method and device.
Background technology
With the development of wireless communication technology, and to low time delay, the further demand of high-speed, draw in the LTE-A stages
Enter new technology, such as carrier aggregation (Carrier Aggregation, CA), relaying Relay technologies, multipoint cooperative CoMP
(Coordinated Multipoint), enhancing coordinating district interference (Enhanced Inter-Cell Interference
Coordination, eICIC) etc. wireless technology.In order to further increase Long Term Evolution (Long Term Evolution, LTE)
Capacity, LTE propositions expand LTE capacity, such as LAA (Licensed-Assisted Access) very much using unlicensed spectrum,
LWA (LTE WLAN Aggregation), LWIP (LTE WLAN Radio Level Integration with IPsec
The technology such as Tunnel).
LWA (LTE WLAN Aggregation) technology proposed in the 3GPP R13 stages, it is not necessary to increase any core
Net section, it is not required that the modification specifications of IEEE 802.11, it is possible to send descending PDCP PDU using WLAN.LWIP(LTE WLAN
Radio Level Integration with IPsec Tunnel) technology, sent by ipsec tunnel agreement using WLAN
Downstream IP data is grouped and upstream IP data packet.

When holding the move between base stations in same Route Area, terminal is currently located the anchor base station that base station is exactly the terminal.But when eventually
End carried out across Route Area it is mobile when, the anchor base station of terminal is still last base station in source routing area.
Downlink data packet forwards：PDN networks first deliver a packet to the anchor base station of the terminal, and then anchor base station is again by number
Terminal, which is transmitted to, according to bag is currently located base station.
Upstream data bag forwards：The packet that terminal is sent, which is first sent to, is currently located base station, is then currently located base station
Anchor base station is relayed to, anchor base station is then forwarded to PDN networks.
