This is a technology for voice transmission using a Wireless Local Area Network (WLAN) that can provide mobile communication services anywhere WiFi is supported. The VoWiFi technology can send out voice data packets through a WiFi network, so that the functions of voice call or video call and the like are realized.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The invention is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
Referring to fig. 2, fig. 2 is an architecture diagram of a cross-operator tracing system provided in an embodiment of the present invention, and a cross-operator VoWiFi tracing architecture is formulated based on a tracing scheme of a single operator. The inter-operator tracing system comprises a first evolution type packet data gateway and a first fixed network AAA/tracing system which are positioned in a first operator, and a second evolution type packet data gateway and a second fixed network AAA/tracing system which are positioned in a second operator.
The first evolution type packet data gateway performs data interaction with a first fixed network AAA/tracing system and a second fixed network AAA/tracing system through a simple workflow service interface SWf; the second evolution type packet data gateway performs data interaction with the first fixed network AAA/tracing system and the second fixed network AAA/tracing system through a simple workflow service interface SWf.
The embodiment of the invention aims to establish a method and a device for tracing the source of a cross-operator by fixed-mobile fusion, and solves the problem of tracing the position of a VoWiFi service of the cross-operator. Specifically, the embodiment of the invention provides a cross-operator fixed-mobile fusion interface tracing scheme for the first time, namely, the cross-operator VoWiFi service tracing is realized by directly interfacing an evolved packet data gateway ePDG with a fixed network AAA/tracing system of the method and a co-established sharing party and transmitting position information.
Furthermore, the IP address identification capability is newly added on the ePDG side of the evolution type packet data gateway in the traceability architecture of different operators so as to distinguish the access broadband information of the different operators. The ePDG side of the evolution type packet data gateway acquires the position information of the current access home gateway of the user from the fixed network AAA/traceability system of the local and co-established sharing party by adopting an extended SWf interface, and the position information is used for representing the position information of the user.
In the embodiment of the invention, an evolved packet data gateway that receives a broadband access message of a user terminal UE is taken as a method, for example, equipment under a traceability architecture of a first operator, such as a first evolved packet data gateway and a first fixed network AAA/traceability system, is taken as the method; the co-established sharer represents the device under the traceability architecture of the second operator as an example illustration.
Referring to fig. 3, fig. 3 is a schematic flow chart of a tracing method across operators, in a user attachment process, an evolved packet data gateway ePDG interacts with a fixed network AAA/tracing system of different operators through an extended SWf interface, and obtains location information of a home gateway currently accessed by a user from the fixed network AAA/tracing system, so as to represent user location information, and the specific tracing process is as follows:
1) The evolution type packet data gateway ePDG (A) sends a Diameter protocol-based Location Query instruction Query-Location-Request to a fixed network AAA/tracing system (B) of a co-established sharing party. In some embodiments, the Query-Location-Request includes a Local IP of the user (i.e., an IP address of the ue for the broadband access device) for querying Location information of the user. Further, the first Location Query instruction Query-Location-Request may further include a port number, an IMSI/MSISDN, etc.
2) And the fixed network AAA/traceability system (B) of the co-established sharing party inquires the response information Query-Location-Answer to the position returned by the evolution packet data gateway ePDG (A).
In some embodiments, if the VoWiFi service is subscribed, the Location Query response message Query-Location-Answer includes a "Success" identifier in response to the subscription information identifier and an Access-Network-Info AVP carrying user Location information. Furthermore, the Location Query response information Query-Location-Answer can also comprise user administrative area information and family broadband account information.
In some embodiments, if the VoWiFi service is not subscribed, the Location Query response message Query-Location-Answer includes a "diameter_error_location_failed" identifier in response to the non-subscription message identifier, and then the ePDG returns a "network_failed" and a backoff_timer in an ike_auth Answer message of the answering user terminal UE, and the attach procedure is terminated.
The inter-operator tracing method is the same as a single-operator scheme, can precisely trace the source to the home address, and has higher precision than VoLTE.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a protocol stack according to an embodiment of the present invention, where on a control plane, user tracing may be implemented through an SWf interface. And the position tracing information is interacted on the SWf interface of the ePDG and the fixed network AAA/tracing system through Diameter information, and a transmission layer of the PI interface uses a TCP protocol.

as shown in fig. 5, the method includes:
when receiving a broadband access message from a user terminal and judging that the broadband access message belongs to broadband access equipment of a second operator, the evolved packet data gateway generates a position inquiry instruction according to the broadband access message and sends the position inquiry instruction to a tracing system;
the tracing system generates position inquiry response information aiming at the position inquiry instruction, and feeds the position inquiry response information back to the evolution type packet data gateway, and the evolution type packet data gateway carries out network tracing according to the position inquiry response information.
Specifically, in this embodiment, the evolved packet data gateway is respectively docked with the fixed network AAA/traceability system of the operator of the sharing party and the co-established shared party, so as to implement the position traceability of the VoWiFi service accessed across the operators, and avoid the risk of core user data leakage caused by direct docking of the co-established shared fixed network AAA/traceability system; the network is simple, no new query step is needed, no sense is felt to the use of the user, and the supervision requirement is met.
Optionally, the embodiment of the invention can replace a tracing system by using the fixed network AAA equipment.
As a preferred embodiment, the broadband access message includes an IP address and a port number of the user terminal for the broadband access device;
the evolved packet data gateway is configured to generate a location query instruction including an IP address and a port number when determining that the broadband access message belongs to the broadband access device of the second operator according to the IP address.
Further, if the evolved packet data gateway determines that the address is the present address according to the IP address, tracing is performed according to a single operator tracing method, which is not described herein again; if the shared party address is judged to be the co-established shared party address, tracing is carried out according to the cross-operator tracing method.
As a preferred embodiment, as shown in fig. 6, the generating, by the tracing system, location query response information for the location query instruction includes:

if not, feeding back the position inquiry response information which is in response to the sign of the non-subscription information.
As a preferred embodiment, the evolved packet data gateway is communicatively connected to a traceability system located at a different operator through a simple workflow service interface.
In some embodiments, the evolved packet data gateway ePDG queries the fixed network AAA/traceability system of the co-established sharer for location information of the home gateway through the SWf interface. The interface messages are classified as QLR. QLR command messages are sent by the evolved packet data gateway ePDG (a) to the fixed network AAA/tracing system (B) for querying the location information of the home gateway accessed by the VoWiFi user by means of a location query instruction.
Illustratively, the message format of the Location Query instruction Query-Location-Request may be:

furthermore, the subscriber-Id AVP carries an international mobile subscriber identity IMSI/mobile station international subscriber directory number MSISDN, which facilitates statistics by the diameter routing agent DRA or the tracing gateway.
Further, the UE-Local-IP-Address AVP and UDP-Source-Port AVP carry the Local IP and Port number of the user (i.e. the exit IP Address and Port number of the home gateway), and the format specification is referred to 3gpp ts29.212.
In some embodiments, the fixed network AAA/tracing system (B) sends the location query response information to the evolved packet data gateway ePDG (a) through a QLA command message.

Further, only Result-Code AVP needs to be filled in for successful inquiry, and 2001 'success' needs to be filled in; the query failure only needs to fill in the superior-Result AVP, the Vendor-Id AVP fill 10415 in the superior-Result AVP represents 3gpp, and the superior-Result-Code AVP fill 4225 represents "diameter_error_position_failure".
Further, the Code value in the Access-Network-Info AVP format is set to 0 (indicating that the Location-Data AVP carries Location Information in civic Location profile format) as shown in 3GPP TS 29.273,Location-Information AVP, and the Location-Data AVP carries Location Information of the home gateway ("administrative area code+country code+local area code+province tag" +operator identifier+networking mode). For the VoWiFi application in the chinese telecom home gateway scenario, SSID AVP fills in "chinanet-home".
Further, where QLA defaults to not carry the Vendor-Specific-Application-Id AVP, the AVP return must also be carried in the QLA message only if the Vendor-Specific-Application-Id AVP is carried in the QLR request.
By the above scheme, assuming that the user A is the user of the operator X, the user A dials the VoWiFi service, and the position tracing comprises the following steps through broadband access of the operator Y:
inquiring DNS according to FQDN reported by the terminal, and acquiring ePDG address of operator X; when the ePDG of the operator X judges that the ePDG is a broadband of the operator Y according to the address, the ePDG performs position inquiry to a fixed network AAA/tracing system of the operator Y; after the internal query of the fixed network AAA/tracing system of the operator Y, the position information of the broadband is acquired and fed back to the ePDG of the operator X, so that the VoWiFi user tracing of the user A is realized.
