Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

At present, wireless voice (voice on WIFI, VOWIFI) services mainly have three networking schemes: an untrusted access 3GPP network (S2b interface, i.e., an interface between an ePDG and a Packet data Gateway (PGW) in a VOWIFI untrusted access scheme), a trusted access 3GPP network (S2a interface, i.e., an interface between a Trunk Gateway (TGW) and a PGW in a VOWIFI trusted access scheme), and a network direct access IMS (S2c interface, i.e., an interface between a terminal and a PGW in a VOWIFI IMS direct connection scheme). For the three networking schemes, analysis is performed from the technical aspect, and particularly from the aspects of influence on the Network and terminal maturity, for an operator who has deployed a large number of Wireless Local Area Network (WLAN) access points, a trusted access 3GPP Network (S2a interface) scheme is adopted, and the whole-Network WLAN access point equipment needs to be upgraded and modified or directly replaced, so that the construction period is long, the cost is high, and the difficulty is high; and by adopting the scheme of the untrusted access 3GPP network (S2b interface), the seamless switching of voice between the WLAN and a Long Term Evolution (LTE) network can be realized at lower cost by combining the openness of a public Wi-Fi network and the characteristics of high reliability, quality of service (QoS) guarantee and the like of an operator core network. Therefore, the untrusted access 3GPP network (S2b interface) solution will gradually replace the trusted access 3GPP network (S2a interface) solution, becoming a more feasible VoWiFi solution accepted in the industry at present. In the scheme, a user terminal accesses to a 3GPP network of an operator through a non-trust domain Wi-Fi network, and after authentication and authorization, a call request is routed to an IP Multimedia System (IMS) for processing, so that IMS services such as voice, short messages, supplementary services and the like are realized. In the solution of the untrusted access 3GPP network (S2b interface), in order to implement the VoWiFi service, only an enhanced packet data gateway (ePDG) and a 3GPP Authentication, Authorization, and Accounting (AAA) network element need to be added.

At present, a mobile phone terminal supports double WIFI, and applications can be networked through any one of the WIFI. The double-WIFI acceleration technology can realize that one mobile phone is connected with two WIFI (2.4G/5G) simultaneously through a network aggregation/distribution algorithm. And the network condition is intelligently judged through an advanced algorithm, so that the network experience is realized. Under the condition of connecting two uplink networks, the downloading speed is higher, the webpage loading is smoother, and the game operation is more stable.

When a terminal initiates VOWIFI service authentication and registration data signaling to an ePDG network element, due to the fact that WIFI is abnormal and signals are weak, the retransmission times of a data packet reach a threshold value, and when IP changes before and after WIFI are inconsistent, VOWIFI attachment signaling and registration message sending are abnormal, so that VOWIFI service abnormality is caused, and user experience is affected.

The invention provides a service processing method, a terminal and network side equipment, aiming at the problems that VOWIFI registration message sending is abnormal and further VOWIFI service is abnormal and user experience is influenced when WIFI is abnormal, signals are weak and IP changes before and after WIFI are inconsistent.

As shown in fig. 1, an embodiment of the present invention provides a service processing method, which is applied to a terminal, and includes:

step 101, when the terminal is connected to at least two wireless network WIFI simultaneously, in the communication process between the terminal and the network side device, if a first WIFI currently used by the terminal is abnormal, selecting a second WIFI in the internet protocol IP list information to send communication data.

It should be noted that, in the communication process between the terminal and the network side device, if the current WIFI used by the terminal is abnormal and the data service cannot be normally sent, the terminal immediately replaces another WIFI to continue sending the data service, so as to avoid the problem of interruption of the communication process.

It should be noted that the above-mentioned occurrence abnormality may include, but is not limited to, at least one of the following cases:

the WIFI signal is weak, the connection between the terminal and the WIFI is disconnected, the packet loss rate of data transmission performed by the terminal through the WIFI exceeds a threshold value, the retransmission times of the data packets reach a preset value when the terminal performs data transmission through the WIFI, and the IP before and after the WIFI is inconsistent when the terminal performs data transmission.

It should be noted that, the network-side device mentioned in the embodiment of the present invention may refer to an enhanced packet data gateway (ePDG) that directly communicates with a terminal in a process that the terminal is attached to an IP Multimedia Subsystem (IMS) core network through WIFI and registers.

It should be noted that, before step 101, the terminal needs to first save the IP list information, and the specific implementation manner is as follows:

acquiring IP address information of at least two WIFI, and storing the IP address information of the at least two WIFI in IP list information;

the arrangement rule of the IP address information in the IP list information is as follows: and the IP address information of the WIFI is arranged in the IP list information from front to back according to the sequence of the network speed of the WIFI from high to low.

It should be noted that the network speed mentioned in the embodiment of the present invention refers to the uploading and downloading speed of the terminal connected to the network in the same network.

It should be noted that, when the terminal is connected with multiple WIFI simultaneously, the terminal obtains IP address information of multiple WIFI through a Dynamic Host Control Protocol (DHCP), and stores the IP address information in IP list information { IP1, IP2, …, IPn }, where the IP list information is sorted according to WIFI network speed, where WIFI network speed is high (which may be understood as the aforementioned network speed is high) and network speed is slow (which may be understood as the aforementioned network speed is low) and is arranged in front of the WIFI network speed; specifically, when the terminal selects the WIFI, according to the sequence of the IP address information in the IP list information, the WIFI corresponding to the IP address information arranged in the front is selected to transmit the data service, and if the selected WIFI cannot complete the data service transmission, the WIFI corresponding to the IP address information arranged in the back is selected in sequence until the WIFI capable of meeting the service data requirement is selected.

It should be further noted that, the communication process between the terminal and the network side device mainly refers to:

in the process that the terminal is attached to an IMS core network through WIFI and registers, the terminal sends a request message to network side equipment;

wherein the request message comprises at least one of:

an Internet Key exchange Security authentication initialization Request (IKE _ SA _ INIT-Request) message;

an internet key exchange authentication request (IKE _ AUTH _ Req) message;

a registration request message.

That is to say, in the process of sending any request message by the terminal, as long as the terminal has an abnormality in currently used WIFI, the terminal immediately performs WIFI replacement, and executes message sending using the replaced WIFI.

It should be further noted that, in order to enable the network side device to clearly know which WIFI the terminal is specifically connected to, usually at an initial stage of a process in which the terminal is attached to the IMS core network through WIFI and registers, the terminal needs to notify the network side device of the IP list information stored by the terminal itself, specifically, the terminal carries the IP list information stored by the terminal in an IKE _ SA _ INIT-Request message sent to the network side device, and the network side device stores the IP list information by itself after receiving the IP list information.

It should be further noted that, when the current WIFI used by the terminal is abnormal, it indicates that the terminal cannot normally use the WIFI, and the terminal needs to delete the unusable WIFI in the IP list information, specifically, the implementation manner is: after step 101, the method of the embodiment of the present invention further includes:

and updating the IP list information.

Specifically, the main implementation manner for updating the IP list information is as follows: and deleting abnormal WIFI, and sequencing the IP address information according to the arrangement rule of the IP address information again.

It should be noted that, after the IP list information is updated by the terminal, the updated IP list information needs to be notified to the terminal, specifically, if the terminal performs WIFI replacement when sending the IKE _ AUTH _ Req message, the IKE _ AUTH _ Req message that is finally sent to the network side device should carry the IP list information, and after receiving the IKE _ AUTH _ Req message that includes the IP list information, the network side device modifies the IP list information stored in the network side device, for example, the network side device updates the IP list information stored in the network side device according to the received IP list information.

It should be further noted that, in order to ensure that the IP list information of the terminal and the IP list information of the network side device are consistent, the terminal and the network side device need to match and update the IP list information periodically, specifically, the following two implementation manners may be adopted:

the method comprises the following steps that a terminal sends IP list information to network side equipment, wherein the IP list information is used for matching and updating the IP list information by the network side equipment;

by the method, the network side equipment can match and update the IP list information stored by the network side equipment according to the IP list information sent by the terminal, namely the IP list information stored by the network side equipment is updated to the IP list information sent by the terminal.

The terminal receives IP list information sent by network side equipment, wherein the IP list information is used for the terminal to match and update an IP list;

by the method, the terminal can be ensured to match and update the IP list information stored by the terminal according to the IP list information sent by the network side equipment, namely, the IP list information stored by the terminal is updated to the IP list information sent by the network side equipment.

It should be further noted that, after the terminal attaches to the IMS core network through WIFI and registers, and the terminal establishes an Internet Protocol Security (IpSec) tunnel link with the network side device, the network side device may send an Internet key exchange information Request (IKE _ information Request) message to the terminal at regular time, or the terminal sends an IKE _ information Request message to the network side device, where the IKE _ information Request message carries IP list information { IP1, IP2, …, IPn }, and the matching and updating of the IP list information { IP1, IP2, …, IPn } of the terminal and the network side device are completed simultaneously in a Dead point detection (Dead point detection, DPD) process.

It should be noted that the embodiment of the present invention can ensure normal sending of the VOWIFI registration message when WIFI is abnormal, the signal is weak, and the IP changes before and after WIFI are inconsistent, thereby ensuring normal operation of the VOWIFI service and improving user experience.

As shown in fig. 2, an embodiment of the present invention further provides a service processing method, which is applied to a network device, and includes:

step 201, when the terminal is connected to at least two wireless networks WIFI at the same time, in the communication process between the network side equipment and the terminal, receiving communication data sent by the terminal through a second WIFI;

Specifically, the communication process between the network side device and the terminal includes:

the method comprises the steps that in the process that a terminal is attached to an IP multimedia subsystem core network through WIFI and is registered, a request message sent by the terminal is received;

wherein the request message comprises at least one of:

internet key exchange security authentication initialization request message;

an internet key exchange authentication request message;

a registration request message.

Optionally, when the request message is an internet key exchange security authentication initialization request message, the internet key exchange security authentication initialization request message carries IP list information.

Further, when the request message is an internet key exchange authentication request message, the internet key exchange authentication request message carries IP list information, and the service processing method further includes:

and modifying the IP list information stored in the network side equipment according to the IP list information carried in the Internet key exchange authentication request message.

Optionally, in the communication process between the network-side device and the terminal, after receiving communication data sent by the terminal through the second WIFI, the method further includes:

and receiving IP list information sent by the terminal, wherein the IP list information is used for the network side equipment to match and update the IP list information.

and sending IP list information to the terminal, wherein the IP list information is used for the terminal to match and update the IP list.

It should be noted that all descriptions regarding the network side device in the foregoing embodiments are applicable to the embodiment of the service processing method, and can achieve the same technical effect, and are not described herein again.

As shown in fig. 3, an embodiment of the present invention further provides a service processing method, which is applied to a network device, and includes:

step 301, when the terminal is connected to at least two wireless network WIFI simultaneously, in a communication process between the network side device and the terminal, if a first WIFI connected between the network side device and the terminal is abnormal, selecting a second WIFI in the internet protocol IP list information to send communication data.

It should be noted that, in the communication process between the network side device and the terminal, if the current WIFI used by the network side device is abnormal and the data service cannot be normally sent, the network side device immediately replaces other WIFI to continue sending the data service, so as to avoid the problem of communication interruption.

the WIFI signal is weak, the network side equipment is disconnected from the WIFI, the packet loss rate of data transmission performed by the network side equipment through the WIFI exceeds a threshold value, the retransmission times of data packets reach a preset value when the network side equipment performs data transmission through the WIFI, and the front IP and the back IP of the WIFI are inconsistent when the network side equipment performs data transmission.

It should be noted here that the network side device may refer to an enhanced packet data gateway (ePDG) that directly communicates with the terminal in a process that the terminal attaches to an IP Multimedia Subsystem (IMS) core network through WIFI and registers.

It should be noted that, before step 301, the network side device needs to first store the IP list information, and the specific implementation manner is:

receiving IP list information sent by a terminal;

wherein, the arrangement rule of the IP address information in the IP list information is as follows: and the IP address information of the WIFI is arranged in the IP list information from front to back according to the sequence of the network speed of the WIFI from high to low.

Specifically, when the network side device selects the WIFI, according to the sequence of the IP address information in the IP list information, the WIFI corresponding to the IP address information arranged in the front is selected to perform data service transmission, and if the selected WIFI cannot complete data service transmission, the WIFI corresponding to the IP address information arranged in the back is selected in sequence until the WIFI capable of meeting the service data requirement is selected.

It should be noted that, in the process that the terminal is attached to the IMS core network through WIFI and registers, the IP list information is generally sent to the network side device through an internet key exchange security authentication initialization Request (IKE _ SA _ INIT-Request) message in the terminal initialization process.

It should be further noted that, the communication process between the network side device and the terminal mainly refers to:

in the process that the terminal is attached to an IP multimedia subsystem core network through WIFI and is registered, the network side equipment sends a response message to the terminal;

wherein the reply message comprises at least one of:

internet key exchange security authentication initialization response message;

internet key exchange authentication response message;

and registering the response message.

That is to say, in the process of sending any response message by the network side device, as long as the currently used WIFI abnormality occurs in the network side device, the network side device immediately performs the replacement of the WIFI, and executes the message sending by using the replaced WIFI.

in the first implementation manner, the network side device sends IP list information to the terminal, and the IP list information is used for the terminal to match and update the IP list.

And secondly, the network side equipment receives IP list information sent by the terminal, wherein the IP list information is used for the network side equipment to match and update the IP list.

It should be further noted that, after the terminal attaches to the IMS core network through WIFI and registers, and the terminal establishes an internet protocol security (IpSec) tunnel link with the network side device, the network side device may send an internet key exchange information Request (IKE _ information Request) message to the terminal at regular time, or the terminal may send an IKE _ information Request message to the network side device, where the IKE _ information Request message carries IP list information { IP1, IP2, …, IPn }, and the matching and updating of the IP list information { IP1, IP2, …, IPn } of the terminal and the network side device are completed simultaneously in a Dead Point Detection (DPD) process.

It should be noted that, under the condition that the terminal is connected to at least two WIFI simultaneously, in the communication process between the network side device and the terminal, if the first WIFI currently used by the network side device is abnormal, the second WIFI is selected from the IP list information to send the communication data, so that it is ensured that when the WIFI is abnormal, the signal is weak, and the IP changes before and after the WIFI are inconsistent, the normal sending of the VOWIFI registration message is ensured, further the normal operation of the VOWIFI service is ensured, and the user experience is improved.

As shown in fig. 4, an embodiment of the present invention further provides a service processing method, which is applied to a terminal, and includes:

Specifically, the communication process between the terminal and the network side device includes:

receiving a response message sent by network side equipment in the process that a terminal is attached to an IP multimedia subsystem core network through WIFI and is registered;

wherein the reply message comprises at least one of:

internet key exchange security authentication initialization response message;

and registering the response message.

Optionally, in the communication process between the terminal and the network side device, after receiving communication data sent by the network side device through the second WIFI, the method further includes:

and receiving IP list information sent by network side equipment, wherein the IP list information is used for the terminal to match and update the IP list.

and sending IP list information to the network side equipment, wherein the IP list information is used for the network side equipment to match and update the IP list.

It should be noted that, all descriptions regarding the terminal in the foregoing embodiments are applicable to the embodiment of the service processing method, and the same technical effect can be achieved, and are not described herein again.

The following is a detailed description of the specific application of the above-described embodiments of the present invention.

In the process that the terminal attaches to the IMS core network through WIFI, the processing flow of the communication process in which the terminal and the ePDG perform signaling interaction applied to the embodiment of the present invention is as shown in fig. 5:

step S501, the terminal is connected with a plurality of WIFI simultaneously;

step S502, the terminal acquires a plurality of WIFI IP address information through DHCP and stores the WIFI IP address information in IP list information { IP1, IP2, … and IPn }, and the list IP information is sorted according to the WIFI network speed, wherein the WIFI network speed is arranged in front, and the WIFI network speed is arranged in back.

Step S503, the terminal sends IKE _ SA _ INIT-Request message to the ePDG, carries the encryption algorithm supported by the terminal, the exchange time random number (nonces), the completion key exchange algorithm (Diffie _ Hellman), and the WIFI IP list { IP1, IP2, …, IPn } stored by the terminal, and prepares to establish IKE connection to the ePDG.

Optionally, if during the execution of step S503, the WIFI1 IP1 connected to the terminal suddenly appears abnormal (for example, the WIFI signal is weak, disconnection occurs, the packet loss rate exceeds the threshold, the number of retransmission times of the data packet reaches the threshold, and the situations that the IPs before and after WIFI1 are inconsistent, etc.), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 also appears abnormal, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

Step S504, after receiving the IKE _ SA _ INIT-Request message, the ePDG completes the encryption algorithm, the time random number, the key exchange, and saves the received IP list information { IP1, IP2, …, IPn } of the WIFI at the ePDG side, and then the ePDG replies the IKE _ SA _ INIT-Answer message to the terminal, carries the negotiated encryption algorithm, the negotiated key and other information, and completes the creation of the IKE connection.

Optionally, assuming that in step S504, an abnormality occurs suddenly in the connected WIFI1 IP1 (for example, in a case that WIFI is disconnected, the number of times of retransmission of a signaling or a data packet to the terminal reaches a preset value, and the like), at this time, the ePDG preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as a target address for sending the signaling to the terminal, and transmits the signaling to the terminal through the WIFI2, if the WIFI2 is also abnormal at this time, the IP3 of the WIFI3 is continuously used, and so on until the IPn of the WIFI; it should be further noted that, after the WIFI1 is abnormal or the number of times of retransmission of the signaling or the data packet to the terminal reaches a preset value, etc., the ePDG replies an IKE _ SA _ INIT-Answer message to the terminal using the WIFI2, which carries information such as the negotiated encryption algorithm and key, and IP list information { IP1, IP2, …, IPn } of the WIFI, thereby completing IKE connection creation. And when the terminal receives the IKE _ SA _ INIT-Answer, the IP list information { IP1, IP2, … and IPn } of the WIFI stored at the terminal is updated, and the IP2 of the WIFI2 is used as the source address of the terminal.

Step S505, the terminal initiates an IKE _ AUTH _ Req message, and performs an Extensible Authentication Protocol (EAP) algorithm negotiation process with the Network side, where the message simultaneously carries information such as SA information for establishing IPsec, Access Point Network (APN) information, Network Access Identifier (NAI), and information such as Proxy Call Session Control Function (P-CSCF) address request, Domain Name Server (DNS) request of the terminal in a configuration request (configuration request) field.

Optionally, assuming that in this step S505, a WIFI1 IP1 connected to the terminal suddenly appears abnormal (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold value, the number of times of data packet retransmission reaches the threshold value, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

Step S506, after receiving the IKE _ AUTH _ Req message from the terminal, the ePDG initiates a Protocol cluster Extensible Authentication Protocol Request (Diameter EAP Request) message to the 3GPP AAA, which carries a User Name (User-Name) field, and the 3GPP AAA determines an Extensible Authentication Protocol (EAP) algorithm supported by the terminal according to the field.

It should be noted that, in step S506, if the terminal changes the WIFI sending the IKE _ AUTH _ Req message to WIFI2, after receiving the IKE _ AUTH _ Req message from the terminal, the ePDG modifies the IP list information { IP1, IP2, …, IPn } of the WIFI stored at the local side, and sets WIFI2 IP2 as a target address for sending signaling or data to the terminal.

Step S507, the 3GPP AAA sends a Multimedia Authentication Request (MAR) message to a Home Subscriber Server (HSS), requesting Authentication and Key Agreement (AKA) Authentication vector.

Step S508, the HSS sends a Multimedia Authentication Answer (MAA) message to the 3GPP AAA, which carries the authentication vector of the AKA.

Step S509, the 3GPP AAA returns a Diameter EAP Answer message carrying an AKA authentication vector to the ePDG.

Step S510, ePDG returns IKE _ AUTH _ Answer message to terminal, carrying EAP authentication data;

optionally, assuming that in step S510, a WIFI1 IP1 connected to the terminal suddenly appears abnormal (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold, the number of data packet retransmissions reaches the threshold, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the WIFI IP list information { IP1, IP2, …, IPn } as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the IP3 of the WIFI3 continues to be used, and so on until the IPn of the WIFI.

Step S511, the terminal verifies the correctness of the parameters according to the local algorithm, simultaneously generates the authentication parameters of the terminal, and initiates an IKE _ AUTH _ Req message to the ePDG;

optionally, assuming that in this step S511, a WIFI1 IP1 connected to the terminal suddenly appears abnormal (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold, the number of times of retransmission of the data packet reaches the threshold, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

Step S512, ePDG initiates Diameter EAP Request message to 3GPP AAA, and passes through authentication parameters of terminal.

Step S513, after the 3GPP AAA verifies the authentication parameter, sends a Server Assignment Request (SAR) message to the HSS, and performs terminal registration.

Step S514, the HSS returns a Server Assignment Answer (SAA) message, and issues an APN and a quality of service Profile (QoS Profile) of the user.

Step S515, the 3GPP AAA returns a Diameter EAP Answer message to the ePDG, and transfers the user subscription data and the generated MSK.

Step S516, the ePDG sends a message of GTPv2 creating Session Request (Create Session Request) to the PDN gateway (P-GW) and establishes an S2b-GTP tunnel.

Step S517, the P-GW sends a Control Request (CCR) message to a Policy and Charging Rules Function (PCRF) to Request a rule corresponding to the user.

Step S518, the PCRF returns a Credit Control Answer (CCA) message, which carries the corresponding rule of the user.

In step S519, the P-GW returns GTPv2 to the ePDG to Create a Session Response (Create Session Response) message, and a GPRS Tunneling Protocol (GTP) tunnel is successful.

Step S520, the ePDG returns IKE _ AUTH _ Answer message to the terminal and transmits EAP-success message to the terminal;

optionally, assuming that in this step S520, a WIFI1 IP1 connected to the terminal suddenly appears abnormal (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold, the number of times of retransmission of the data packet reaches the threshold, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

Step S521, the terminal initiates IKE _ AUTH _ Req message to ePDG, initiates negotiation for establishing IPsec installation alliance, and completes IPsec tunnel establishment;

optionally, assuming that in this step S521, a WIFI1 IP1 connected to the terminal suddenly appears abnormally (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold value, the number of times of retransmission of the data packet reaches the threshold value, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

Step S522, after the IPsec tunnel is established, the ePDG sends the IP address distributed to the terminal by the network side, the acquired information such as DNS, P-CSCF and the like to the terminal through the IKE _ AUTH _ Answer message.

Optionally, assuming that in this step S522, the connected WIFI1 IP1 suddenly appears abnormal (for example, WIFI disconnection, the number of times of retransmission of the signaling or the data packet to the terminal reaches a preset value, and the like), at this time, the ePDG preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as a destination address for sending the signaling to the terminal, and transmits the signaling to the terminal through the WIFI2, if the WIFI2 is also abnormal at this time, the IP3 of the WIFI3 continues to be used, and so on until the IPn of the WIFI.

It should be noted that, in the process of communication between the terminal and the ePDG, if a WIFI abnormality occurs in any information transmission process, the party sending the information immediately performs WIFI replacement to ensure accurate transmission of the information

After the terminal establishes an IpSec tunnel link with the ePDG, the terminal sends an IKE _ information Request message to the ePDG, and when the used WIFI is suddenly abnormal, as shown in fig. 6, the specific implementation flow is as follows:

the terminal sends an IKE _ information Request message to the ePDG at regular time to perform DPD detection, and the method specifically comprises the following steps:

step S601, after the terminal establishes an IpSec tunnel link with the ePDG, the terminal sends an IKE _ information Request message to the ePDG terminal at a fixed time, and the message carries IP list information { IP1, IP2, …, IPn } of WIFI for updating the IP list information of WIFI of the ePDG.

Optionally, assuming that in this step, an abnormality occurs suddenly in the connected WIFI1 IP1 (for example, the WIFI signal is weak, the WIFI is disconnected, the packet loss rate exceeds the threshold value, the number of times of retransmission of the data packet reaches the preset value, and the IPs before and after WIFI1 are inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

In step S602, after receiving the IKE _ information Request message, the ePDG replies an IKE _ information Response message to the terminal, which is used to confirm to the ePDG that the terminal is still in a normal connection state, and update the WIFI IP list information of the ePDG.

After the terminal establishes an IpSec tunnel link with the ePDG, the ePDG sends an IKE _ information Request message to the terminal at a regular time, and when the used WIFI is suddenly abnormal, as shown in fig. 7, the specific implementation flow is as follows:

the ePDG sends IKE _ information Request message to the terminal at regular time to perform DPD detection, and the method specifically comprises the following steps:

in step S701, after the terminal establishes an IpSec tunnel link with the ePDG, the ePDG sends an IKE _ information Request message to the terminal at a regular time, and the message carries WIFI IP list information { IP1, IP2, …, IPn }, which is used for matching and updating with WIFI IP list information { IP1, IP2, …, IPn } stored at the terminal side.

Assuming that in step S701, the connected WIFI1 IP1 suddenly appears abnormal (for example, WIFI disconnection, the number of times of retransmission of a signaling or a data packet to the terminal reaches a preset value, and the like), at this time, the ePDG preferentially uses the address of the WIFI2 IP2 in the WIFI IP list { IP1, IP2, …, IPn } as a destination address for sending a signaling to the terminal, and transmits the signaling to the terminal through the WIFI2, if the WIFI2 is also abnormal, the IP3 of the WIFI3 continues to be used, and so on until the IPn of the WIFI.

After the WIFI1 is abnormal or the retransmission times of the signaling or the data packet to the terminal reach a preset value, the ePDG uses the WIFI2 to send an IKE _ information Request message to the terminal. And after receiving the IKE _ information Request message, the terminal matches and updates the WIFI IP list information { IP1, IP2, … and IPn } stored at the terminal side, and takes the IP2 of the WIFI2 as the source address of the terminal.

Step S702, after receiving the IKE _ information Request message, the terminal replies an IKE _ information Response message to the ePDG, which is used to confirm to the ePDG that the terminal is still in a normal connection state, match the WIFI IP list information delivered by the ePDG, and place the latest WIFI IP list information { IP1, IP2, …, IPn } in the IKE _ information Response message to send to the ePDG.

It should be further noted that, as shown in fig. 8, in the terminal registration process, a specific implementation process applying the embodiment of the present invention is (it should be noted that Proxy in fig. 8 may be ePDG, and Register and Location Server are other network elements of the IMS core network, such as main network elements of P-CSCF, I-CSCF, and S-CSCF):

Step S802, the proxy server sends a registration request message to a registration server (Register);

step S803, the registration server confirms that the user is not authenticated, and returns an unauthorized registration response message to the proxy server;

step S804, the proxy server sends an unauthorized registration response message to the terminal;

optionally, in step S804, a WIFI1 IP1 connected to the terminal suddenly appears abnormal (e.g., a WIFI signal is weak, the WIFI signal is disconnected, a packet loss rate exceeds a threshold value, the number of times of retransmission of a data packet reaches a preset value, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses an address of a WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as a sending address of the terminal side, and transmits a signaling to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and if the WIFI2 is abnormal, the terminal continues to use the IPn of the WIFI.

Step S805, the proxy server sends the registration request message to the registration server again;

Step S806, the proxy server sends a registration request message to the registration server;

step S807, the registration Server determines that the user authentication is passed, and sends registration information to a Location Server (Location Server);

step S808, the registration server determines that the user passes the authentication, and returns a registration response message passing the authentication to the proxy server;

step S809, the proxy server sends a registration response message passing the authentication to the terminal;

optionally, in step S809, a WIFI1 IP1 connected to the terminal suddenly appears abnormally (for example, the WIFI signal is weak, the WIFI signal is disconnected, the packet loss rate exceeds the threshold value, the number of times of retransmission of the data packet reaches the preset value, and the IP before and after WIFI1 is inconsistent), at this time, the terminal preferentially uses the address of the WIFI2 IP2 in the IP list information { IP1, IP2, …, IPn } of the WIFI as the sending address of the terminal side, and transmits the signal to the ePDG through the WIFI2, if the WIFI2 is also abnormal at this time, the terminal continues to use the IP3 of the WIFI3, and so on until the IPn of the WIFI.

It should be noted that, in the implementation manner of the present invention, by combining dual WIFI or a subsequent multi-WIFI technology that may occur, a VOWIFI service processing flow is optimized, a VOWIFI service is processed by switching among multiple WIFI, a phenomenon that a terminal VOWIFI is unregistered or registration delay is long can be reduced, and user experience is improved.
