The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , an embodiment of the present invention provides a method for transmitting a multiple access technology, including: 11. Receiving an APN (Access Point Name) letter initiated by a User Equipment (User Equipment) The activation APN signaling includes a multi-access technology transmission indication.

12. Generate an upstream template according to the multi-access technology transmission indication, where the uplink template includes a binding relationship between the IP flow and the access technology.

13. The uplink template is transmitted to the UE, so that the UE performs the multi-connection on the PDN (Packet Data Network) connection of the PDN (Packet Data Network) connection that needs to be transmitted by using the APN signaling to activate the APN signaling according to the upstream template. Into technology transmission.

The execution entity of the multiple access technology transmission method in the embodiment of the present invention may be a PGW (PDN Gateway, PDN Gateway). The UE can access different access technologies at the same time, and the UE can transmit the IP flows of one PDN connection on different access technologies. In an embodiment, the IP flows may be the same IP flow or different IP flows.

The UE accessing different access technologies at the same time may include: simultaneously accessing an LTE (Long Term Evolve) network and a WLAN (Wireless Local Area Networks), or simultaneously accessing 3G (3rd Generation, third generation) Mobile communication) Network and WLAN.

As shown in the foregoing technical solution of the present invention, the uplink template that includes the binding relationship between the IP flow and the access technology is transmitted to the UE by the PGW, so that the UE performs multiple access to the IP flow of the PDN connection according to the upstream template. Transmission of technology.

Specifically, the step 11 receives the activated APN signaling initiated by the UE, and can be implemented in the following manner:

The UE has obtained a PDN connection by activating the APN signaling on the WLAN. When the UE accesses the LTE network and needs to perform multiple access technology transmission on the PDN connection, the UE sends the activated APN signaling to the MME on the LTE network (Mobility). Management Entity, GPRS Service Support Node, SGSN (Service GPRS Supporting Node), the activation of APN signaling includes an indication of the need for multiple access technology transmissions for the PDN connection corresponding to the APN. The MME/SGSN sends a session establishment message to the SGW (Serving Gateway), the session establishment message Contains the APN and multiple access technology transmission indications. The SGW sends a session establishment message to the PGW, and the session establishment message includes the APN and the multiple access technology transmission indication.

Alternatively, the UE has obtained a PDN connection by activating the APN signaling on the LTE network or the 3G network. When the UE accesses from the WLAN and needs to perform multiple access technology transmission on the PDN connection, the UE sends an activated APN message on the WLAN. For the ePDG (Evolved Packet Data Gateway), the activation of the APN signaling includes an indication that the PDN connection corresponding to the APN needs to be transmitted by the multiple access technology. When the ePDG uses the PMIP protocol (Proxy MobilelP, the proxy mobile IP accesses the core network, the ePDG sends a PBU (proxy binding update) message to the PGW, or when the ePDG uses the GTP (GPRS tunnel protocol, GPRS tunneling protocol, General) When the Packet Radio Service accesses the core network, the ePDG sends a session establishment message to the PGW, and the session establishment message includes the APN and the multiple access technology transmission indication.

Specifically, the method for transmitting the multiple access technology in the embodiment of the present invention may include the following manners before receiving the activated APN signaling initiated by the UE in step 11:

The PGW determines to transmit a multiple access technology transmission indication to the UE and transmits a multiple access technology transmission indication to the UE to instruct the UE to initiate activation of the APN signaling.

Alternatively, the PGW transmits a multiple access technology transmission indication to the UE, and the multiple access technology transmission indication is transmitted by the PCRF entity to the PGW to instruct the UE to initiate activation of the APN signaling.

In the foregoing embodiment, the network side determines to perform multiple access technology transmission on a certain PDN connection, and the network side transmits a multiple access technology transmission indication to the UE to instruct the UE to initiate activation of APN signaling.

For example, as shown in FIG. 2, the UE has obtained a PDN connection by activating the APN signaling in the LTE network as an example, indicating that the network side decides to perform multiple access technology transmission on a certain PDN connection, and the network side transmits multiple The access technology transmits an indication to the UE:

21. The UE sends the activated APN signaling to the network side to establish a PDN connection.

22. The PCRF entity sends an IP CAN session establish message to the PGW, and the IP CAN session establish message includes an indication of multiple access technology transmission for the PDN connection.

Alternatively, the PCRF entity does not send an indication of the PDN connection for multi-access technology transmission to the PGW, and the PGW decides to perform multi-access technology transmission on the PDN connection.

The PCRF entity or the PGW can determine whether to perform multi-access technology transmission according to the service type of the PDN connection. For example, the service type of the PDN connection is connected to the Internet. For the network, the PDN connection can be transmitted by multiple access technologies, taking full advantage of the bandwidth and tariffs of different access technologies.

23. The PGW informs the SGW of the indication of the multi-access technology transmission of the PDN connection by using a Create session response message, and the Create session response message includes an indication for performing multi-access technology transmission on the PDN connection.

24. The SGW informs the MME of the indication of the multi-access technology transmission of the PDN connection by using a Create session response message, and the Create session response message includes an indication for performing multi-access technology transmission on the PDN connection.

25. The MME informs the UE of the indication of the multi-access technology transmission of the PDN connection by using an Attach accept message or a PDN connection active response message, and the Attach accept message or the PDN connection active response message includes An indication of multi-access technology transmission for the PDN connection.

Subsequently, the UE may initiate activation of APN signaling for the PDN connection, and activate the APN signaling to include a multi-access technology transmission indication.

Optionally, before the method for generating the uplink template according to the multiple access technology transmission indication, the method for transmitting the multiple access technology in the embodiment of the present invention may include the following manners:

The PGW receives the IP stream transmission rule sent by the PCRF entity, and the IP stream transmission rule includes the binding relationship between the IP stream and the access technology.

That is, the PGW obtains an IP flow transmission rule from the PCRF entity, and then the PGW generates an upstream flow template according to the multiple access technology transmission indication, where the upstream flow template includes a binding relationship between the IP flow and the access technology.

Exemplarily, as shown in FIG. 3, the PCRF entity sends an IP flow transmission rule to the PGW, and the PGW generates an upstream flow template according to the IP flow transmission rule, which can be implemented in the following manner:

31. The PCRF entity determines an IP flow transmission rule for performing multi-access technology transmission on the PDN connection.

32. The PCRF entity triggers an IP CAN session modification process to send the IP flow transmission rule of the multiple access technology to the PGW.

33. The PGW generates an upstream flow template according to the IP flow transmission rule, where the uplink flow template includes a binding relationship between the IP flow and the access technology.

34. The PGW sends an uplink template to the UE. For example, the PGW sends a bearer setup or bearer modification message to the SGW, and the SGW sends a bearer setup or bearer modification message to the MME, and the MME passes The NAS (Non-Access Stratum) message is sent to the UE, and the bearer setup or bearer modification message includes an upstream template.

Optionally, before step 31, the PGW may notify the PCRF that the UE can use the multi-access technology to transmit.

The upstream template is a TFT (Traffic Flow Template). The upstream flow template includes binding between the IP flow and the access technology, and may include: a binding relationship or a default binding relationship.

The binding relationship includes: The IP specified by the upstream template is uploaded in the access technology specified by the upstream template. The binding relationship may further include: preferentially binding the relationship or forcing the binding relationship.

The default binding relationship includes: the IP flow other than the IP flow specified by the upstream template is transmitted on the second access technology specified by the upstream template.

Exemplarily, when the UE has an uplink IP flow to be transmitted, the judgment order of the UE side is: if only one access technology is available, all uplink IP flows are delivered to the access technology transmission; otherwise, according to the IP flow and access technology The binding relationship is transmitted.

The upstream template contains multiple filter rules. The filter rules specify IP flows. The filter rules can include IP quintuple, SPI (IP Security Parameter Index), and TOS (Type of Service). All or part of the information of the traffic class and the flow label. The IP quintuple includes a source IP address, a destination IP address, a source port, a destination port, and a protocol number.

Specifically, the priority binding relationship is: the IP flow specified by the filter is preferentially transmitted on an access technology specified by the uplink template. If the access technology does not exist or the transmission fails on the access technology, The IP stream specified by filter can be transmitted on other access technologies.

The mandatory binding relationship is as follows: The IP stream specified by the filter can only be transmitted on an access technology specified by the upstream template.

The default binding relationship is as follows: The IP flows other than the IP flows specified by the filter are transmitted on an access technology specified by the upstream template.

Exemplarily, if a PDN connection is required to be transmitted on an access technology (the IP address of the PDN connection is IP1), the filter rule may include only the source address IP1, and the source address IP1 is bound to the access technology. The UE may transmit the data packet whose source address is IP1 on the access technology. Optionally, the PGW receiving the UE-initiated APN signaling in the step 11 may include the IP address of the PDN connection. At this time, the PGW receives the activated APN signaling initiated by the UE, and determines to perform the multi-access technology transmission according to the IP address of the PDN connection. PDN connection.

Specifically, if an APN is activated multiple times, that is, one APN is associated with multiple PDN connections, usually the UE attempts to activate the APN until the returned IP address is the IP address corresponding to the PDN connection that the UE wants to activate. The different IP flows of the PDN connection are transmitted in the multi-access technology, and there is a defect of low efficiency.

Exemplarily, as shown in FIG. 4, the UE has accessed the LTE network and one APN is activated multiple times, and the UE accesses the WLAN again. The PGW determines that multiple access technology transmission needs to be performed on a certain PDN connection, including:

41. The UE carries the IP address of the PDN connection for performing the multiple access technology transmission to the ePDG in the activated APN signaling. For example, the UE sends a ΙΚΕν2 (ΑΡΝ,ΙΡ address) message to the ePDG, and the IKEv2 (ΑΡΝ,ΙΡ address) message includes the APN. And IP address, IKEv2 (Internet Key Exchange, Internet Key Exchange Protocol).

42. The ePDG carries the IP address to the PGW by using the signaling. For example, the ePDG sends a PBU message or a session establishment message to the PGW. The PBU message or the session establishment message includes an IP address and an APN to the PGW, and the PBU message is a PBU (ΑΡΝ, ΙΡ address). .

43. The PGW accurately determines the PDN connection according to the IP address, and the PGW sends a PBA (Proxy Bnding Acknowledgement) message or a session establishment response message to the ePDG, and the PBA message is, for example, PB A (IP address).

Next, the ePDG sends IKEv2 (ΑΡΝ, ΙΡ address) to the UE.

It can be seen that the UE can carry the IP address of the PDN connection when the APN is activated, and the PGW knows that the PDN connection corresponding to the IP address needs to be transmitted by multiple access technologies. In the case that the APN is activated multiple times, the UE does not need to perform multiple times. Try to activate the APN to improve the efficiency of the transmission of multiple access technologies.

Optionally, the method for transmitting the multiple access technology in the embodiment of the present invention may further include:

The PGW obtains the QoS information of the WLAN.

The PGW sends the QoS quality of service information to the PCRF entity to determine whether to distribute the IP flows on the WLAN over LTE.

Exemplarily, as shown in FIG. 5, the UE accesses the WLAN and the LTE network at the same time, and the UE reports the quality of service of the WLAN to the network side, and the network side determines whether to put the IP stream into the LTE for transmission: The UE determines the QoS (Quality of Service) information of the WLAN. For example, the UE can determine the WLAN service quality by using statistics such as the number of WLAN air interface retransmissions or the packet loss delay jitter of the IP layer.

52. The UE notifies the ePDG after determining the QoS difference of the WLAN.

53. The ePDG notifies the WLAN of the Qos difference to the PGW.

54. The PGW then notifies the WLAN of the Qos difference to the PCRF entity.

55. The PCRF entity determines whether to configure the WLAN IP flow to be transmitted on the LTE.

Optionally, in 52, the ePDG can directly notify the WLAN of the Qos difference information to the PCRF entity.

Optionally, in the 51, the UE may notify the MME (Mobility Management Entity, mobility management entity) of the Qos difference of the WLAN by sending a NAS (Non-Access Stratum) message, and the MME passes the SGW (Serving Gateway). , the service gateway) or the PGW notifies the PCRF entity.

Optionally, the ePDG or the PGW may also be used to determine the Qos of the WLAN.

If the ePDG determines the QoS of the WLAN, the ePDG directly notifies the PCRF entity or notifies the PGW to notify the PCRF entity.

If the PGW determines the QoS of the WLAN, the PGW directly notifies the PCRF entity.

It can be seen that the UE accesses different access technologies at the same time, for example, when accessing the LTE network and the WLAN, or simultaneously accessing the 3G network and the WLAN, or simultaneously accessing the LTE network and the 3G network, when the WLAN service quality is poor. The network side can decide whether to put the IP stream on the LTE network or the 3G network for transmission.
