【Embodiment 1】Downlink data transmission flow
Scene：Base station is by the PDCP PDU of downlink separation carrying by WLAN link transmissions to UE, the corresponding PDCP realities of UE
Body receives the PDCP PDU.
Downlink data transmission flow includes：
Step 1：Base station determines that separation needs the PDCP PDU transmitted by the sides WLAN on carrying according to the strategy of oneself,
Then it is subject to General Packet Radio Service (General Packet Radio Service, GPRS) tunnel protocol (GPRS
Tunneling Protocol, GTP)/User Datagram Protocol (User Datagram Protocol, UDP)/Internet Protocol
(Internet Protocol, IP) is encapsulated, and by the Xw-U interfaces between base station and WAF, is sent to via the tunnels GTP-U
WAF。
Wherein, GTP/UDP/IP encapsulation, i.e. GTP tunnel encapsulate, and belong to existing method, are exactly successively to add head.
Step 2：WAF receives the PDCP PDU shunted from 3GPP system side group station (through GTP/ by the tunnels GTP-U
UDP/IP encapsulate), after receiving, WAF according to the termination point of a tunnel in its packet header GTP identify (Tunnel Endpoint Identifier,
TEID oneself internal TEID and UE) is searched in the IP address of the sides WLAN and the mapping table of LCID, obtains the PDCP PDU couple
IP address and the PDCP PDU corresponding LCID of the UE answered in the sides WLAN.
Step 3：The fronts PDCP PDU are payload plus LCID fields by PWAL layers of the sides WAF, are encapsulated in a new IP
Bao Zhong, the source addresses of the IP packets are WAF (for example UE is in WLAN in the IP address of the sides WLAN or the particular ip address made an appointment
IP address of the IP address of side or some agreement), the destination addresses of the IP packets is the UE in the IP address of the sides WLAN, is then pressed
According to normal WLAN data transmission flow (i.e. existing procedure), by data tunnel between AC-AP or directly by WLAN MAC,
The IP packets are sent to UE.
Step 4：The MAC layer of UE receives flow (i.e. existing procedure) by normal WLAN data and receives the IP packets, transfers to
Its PWAL layers of processing, PWAL are judged according to the source address of the IP packets first, if the source address is IPs of the WAF in the sides WLAN
Address or the particular ip address made an appointment then think that the IP packets come from 3GPP system side, which continues by PWAL layers
Reason directly transfers to IP high levels to handle, that is, carries out existing application layer/TCP/IP processing otherwise it is assumed that the IP packets come from the sides WLAN
Flow.
Step 5：The PWAL layers of UE take out payload, obtain LCID and PDCP PDU to the IP packets from 3GPP system side,
The corresponding PDCP entity handles of PDCP layers that the PDCP PDU are transferred to UE according to the LCID complete the PDCP by the PDCP layers of UE
Functions are submitted etc. in the decryption of PDU to high level, complete the shunting transmission that PDCP is carried on the sides WLAN.
【Embodiment 2】Transmitting uplink data flow
Scene：UE is by the PDCP PDU of uplink separation carrying by WLAN link transmissions to base station, the corresponding PDCP in base station
Entity receives.
Transmitting uplink data flow (PDCP separation carrying) includes：
Step 1：PDCP layers of the sides UE will determine that the PDCP PDU of separation carrying transfer to the PWAL layers of oneself to handle, PWAL needles
Its LCID is determined to corresponding PDCP entities, plus LCID fields is payload by the fronts PDCP PDU, be encapsulated in one it is new
In IP packets, the destination address of IP packets is particular ip address of the WAF in the IP address of the sides WLAN or certain agreement, the source address of IP packets
It is IP address of the UE in the sides WLAN, and according to normal WLAN data transmission flow, which is sent to WAF.
Step 2：WAF receives flow ((i.e. existing procedure)) (or via the tunnels AP-AC) by normal WLAN data
The IP packets are received, transfer to its PWAL layers of processing, PWAL is filtered according to the destination address of the IP packets first, if the destination
Location is WAF or the particular ip address of certain agreement, then it is assumed that the IP packets are 3GPP separation carryings, continue to be handled by PWAL layers, no
Then think that the IP packets are sent to the sides WLAN, directly transfers to IP high levels to handle, that is, carry out existing application layer/TCP/IP process flows.

Mapping table, the TEID which corresponds to the packet header GTP is obtained according to LCID, by the PDCP PDU be subject to GTP/UDP/IP encapsulation, obtain
To GTP wrappers, wherein TEID is a domain in the packet header of GTP wrappers, which passes through between base station and WAF
Xw-U interfaces are sent to base station via the tunnels GTP-U.
Step 4：Base station receives the PDCP PDU by the tunnels GTP-U, according to TEID-LCID mapping relations, by the PDCP
PDU transfers to corresponding PDCP entity handles, from the PDCP layers of decryption for completing the PDCP PDU, submits function to high level, completes PDCP
It is carried through the shunting transmission of the sides WLAN.
【Embodiment 3】The acquisition of WAF IP address
Scene：WAF when initial Xw-C signalling paths are established by the IP address of oneself side WLAN notify base station, base station for
IP address when UE configuration separation carryings by special RRC message by WAF in the sides WLAN notifies UE.
UE obtains WAF：
Step 1：By Signalling exchange between base station and WAF, Xw-C signalling paths are established, WAF is by oneself IP in the sides WLAN
Address notifies base station as parameter, and base station is preserved.
Step 2：Base station is determined as the sides UE activation WLAN aggregation transfer function, and UE access WLAN is indicated by RRC signaling.
Step 3：UE accesses corresponding WLAN according to base station instruction, and access result is returned base station, and base station is according to oneself
Mapping table and UE Results confirm its corresponding WAF.
Step 4：Base station is determined as UE and enables WLAN separation carryings, and separation is carried configuration by RRC specialized configurations message
IP address of the information together with WAF in the sides WLAN notifies UE.
It should be noted that IP address of the WAF of above-mentioned transmission in the sides WLAN can also be UE the sides WLAN IP address,
Certain particular ip address or certain agreement IP address, that is, be used for mark IP packets be from or be sent to 3GPP system side IP packets mark
Know.
As another form of above-described embodiment, two can also be merged into one to step 4 the step of above-described embodiment 3
Step executes, i.e.,：The sides base station activation WLAN aggregation transfer function notifies the WLAN of UE access using RRC signaling, enables carrying separation
