All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic diagram of a network scenario of the service data routing method of the present invention. As shown in fig. 2, the terminal accesses the network through the mobile wireless hotspot, the DNS device is located in the internet, and the S-GW (Serving GateWay), the P-GW, the ePDG, and the IMS are located in the operator intranet. For the non-trusted WiFi application scenario applied by the invention, the ePDG is a border gateway of an operator intranet.
It should be clear to those skilled in the art that fig. 2 is an application scenario of the service data routing method of the present invention. As required, those skilled in the art may apply the service data routing method of the present invention to other network scenarios, which are not described herein again.
A traffic data routing method according to an embodiment of the present invention is described below with reference to fig. 3.
Fig. 3 is a flowchart of an embodiment of a service data routing method according to the present invention. As shown in fig. 3, the method of this embodiment includes:
step S302, the mobile wireless hotspot sends a mobile wireless hotspot type identifier to the accessed terminal.
The mobile wireless hotspot may be a MiFi device or a cellular data terminal device with a WiFi hotspot opened, for example, a mobile phone with a WiFi hotspot opened, a tablet computer with a cellular data access function, and the like.
The common WiFi hotspot device is a WiFi device accessed to a broadband metropolitan area network, and user data is accessed to the common WiFi hotspot through WiFi and then is accessed to the Internet through the broadband metropolitan area network, so that the problem that the data passes through the P-GW twice does not exist. The mobile wireless hotspot devices such as the MiFi and the like can also provide WiFi access for users, and different from the common WiFi hotspot devices, the mobile wireless hotspot devices can transmit data sent by the terminal to an EPC network of an operator through a cellular network.
Therefore, when the terminal accesses the mobile wireless hotspot, the mobile wireless hotspot can send an identifier to the terminal so as to indicate that the hotspot type accessed by the terminal is the mobile wireless hotspot. When the terminal accesses to the common hotspot, the common hotspot may also send a non-mobile wireless hotspot identification, or not send an identification. And if the terminal does not receive the identification, the hotspot accessed by the terminal is a non-mobile wireless hotspot.
The mobile wireless hotspot may add a cell, i.e., a field identifying the type of the hotspot, to an air interface Beacon (Beacon) frame of WiFi, and send the Beacon frame to the terminal. For example, when the field value identifying the hotspot type is 0, it may indicate that the hotspot is a non-mobile wireless hotspot; when the field value of the hotspot type is 1, it may be indicated that the hotspot is a mobile wireless hotspot.
Step S304, the terminal obtains a domain name resolution result for the ePDG sent by the DNS according to the mobile wireless hotspot type identification sent by the mobile wireless hotspot, wherein the domain name resolution result comprises the intranet IP address of the ePDG.
The terminal can send a domain name resolution request for the ePDG to the DNS, and the DNS can return a domain name resolution result according to the request sent by the terminal, and the result includes the intranet IP address of the ePDG.
Step S306, the terminal establishes a tunnel with the ePDG according to the intranet IP address of the ePDG, so that the ePDG can send the service data of the terminal to the service equipment of the intranet.
One embodiment is that the terminal first sends a secure tunnel establishment request to the ePDG through the S-GW by using the intranet IP address of the ePDG, for example, the terminal may initiate an IKEv2(Internet Key exchange version 2, upgraded version of Key exchange protocol) message to the ePDG by using the intranet IP address of the ePDG; the S-GW forwards the safety tunnel establishment request to the ePDG through the intranet based on the intranet IP address of the ePDG in the destination address; then, the terminal establishes a secure tunnel with the ePDG, for example, an IPSec (Internet Protocol Security) tunnel, thereby completing EPC authentication; furthermore, the terminal may send the service data to the service device of the intranet through the secure tunnel.
The service data includes data service based on WiFi access, which may be, for example, VoWiFi, network video service based on WiFi access, and the like. Therefore, the method and the device can be applied to application scenes that the terminal accesses to the cellular data network through WiFi.
When the service data is multimedia data such as VoWiFi, the terminal can register to the IMS through the P-GW after completing EPC authentication, so that the multimedia data can be routed to the multimedia data processing equipment.
The terminal is adopted to obtain the domain name resolution result of the intranet IP address including the ePDG sent by the DNS according to the mobile wireless hotspot type identification sent by the mobile wireless hotspot, so that an intranet tunnel can be established according to the intranet IP address of the ePDG and the ePDG, service data does not need to pass through an intranet and then enter the intranet, and does not need to pass through a public data network gateway twice, the service data transmission delay and the network resource overhead are reduced, and the user experience is improved.
Various methods can be adopted to obtain the intranet IP address of the ePDG from the DNS. Two methods for acquiring the intranet IP address of the ePDG are exemplarily described below with reference to fig. 4 and 5.
Fig. 4 is a flowchart of an embodiment of an intranet IP address acquisition method of an ePDG. As shown in fig. 4, the method of this embodiment includes:
in step S402, the terminal sends a domain name resolution request for the ePDG to the DNS.
The terminal may generate an FQDN (full domain name) corresponding to a conventional ePDG according to the 3GPP standard and send the FQDN to the DNS. That is, the same FQDN, for example, "epdg.epc.mnc 011.mcc460.pub.3gppnetwork.org", is transmitted regardless of what type of hotspot the terminal accesses.
Step S404, the DNS returns a domain name resolution result of the ePDG to the terminal, and the domain name resolution result comprises a corresponding relation between the mobile wireless hotspot type identifier and an internal network IP address of the ePDG and a corresponding relation between the non-mobile wireless hotspot type identifier and an external network IP address of the ePDG.
The DNS returns a domain name resolution result including the intranet IP address and the extranet IP address of the ePDG for all domain name resolution requests for the ePDG sent by the terminal, and the terminal selects which address to use.
In addition, the DNS can also return the correspondence between the blank hotspot type identifier and the external network IP address of the ePDG. Therefore, when the wireless hotspot accessed by the terminal does not send the hotspot type to the terminal, the terminal can still obtain the domain name resolution result sent by the DNS, and access the ePDG from the internet according to a common flow.
Step S406, if the terminal accesses the mobile wireless hotspot, the terminal selects an intranet IP address of the ePDG; and if the terminal accesses the non-mobile wireless hotspot, the terminal selects the external network IP address of the ePDG.
By adopting the method, the DNS can send the intranet IP address and the extranet IP address of the ePDG aiming at all domain name resolution requests to the ePDG, so that the terminal can select the intranet IP address of the ePDG according to the obtained mobile wireless hotspot type identifier.
Fig. 5 is a flowchart of another embodiment of an intranet IP address acquisition method of an ePDG. As shown in fig. 5, the method of this embodiment includes:
step S502, the terminal generates a domain name resolution request of the ePDG corresponding to the mobile wireless hotspot type identification according to the mobile wireless hotspot type identification sent by the mobile wireless hotspot.
In this embodiment, when the terminal is accessed to a mobile wireless hotspot, the terminal may generate a domain name resolution request of an ePDG corresponding to the mobile wireless hotspot type identifier, that is, a domain name resolution request different from that of an access ordinary hotspot.
For example, when the terminal accesses a mobile wireless hotspot and accesses a non-mobile wireless hotspot, different domain names may be included in the sent domain name resolution request. Taking the FQDN as an example, when the terminal accesses the non-mobile wireless hotspot, the generated FQDN may be, for example, "epdg.epc.mnc 011.mcc460.pub.3gppnetwork.org"; when the terminal accesses the mobile wireless hotspot, the generated FQDN may be, for example, "epdg 1.epc. mnc011.mcc460.pub.3gppnetwork. org".
Step S504, the terminal sends a domain name resolution request of the ePDG corresponding to the mobile wireless hotspot type identifier to the DNS.
Step S506, the DNS responds to the domain name resolution request of the ePDG corresponding to the hotspot type identifier of the mobile wireless hotspot, and sends a domain name resolution result to the terminal, where the domain name resolution result includes an intranet IP address of the ePDG.
And the DNS only sends the intranet IP address of the ePDG to the terminal when acquiring the domain name resolution request of the ePDG corresponding to the hotspot type identifier of the mobile wireless hotspot.
By adopting the method, the terminal can generate a domain name resolution request according to the hotspot type of the accessed wireless hotspot and receive a resolution result which is returned by the DNS and aims at the hotspot type of the wireless hotspot. Therefore, the terminal can obtain the intranet IP address of the ePDG when accessing the mobile wireless hotspot.
