Embodiment 1

[0070] In this embodiment, the IP address information of the evolved packet data gateway is first set on the LTE network communication device; then the LTE network communication device transmits the IP address information of the evolved packet data gateway to the terminal through the LTE network. Then, when the terminal attaches to the WiFi network and needs to initiate a WiFi voice service (i.e. VoWiFi service), it establishes a communication connection with the corresponding evolved packet data gateway according to the IP address information of the evolved packet data gateway transmitted by the LTE network communication device, and then passes the The evolved packet data gateway initiates the WIFI voice service. Therefore, the terminal in this embodiment does not depend on the deployment of the DNS device, and can directly discover the evolved packet data gateway through the LTE network, which is simple to implement and has high efficiency in discovering the evolved packet da...

Embodiment 2

[0087] In this embodiment, the LTE network communication device is taken as a mobile management entity (MME), a serving gateway (Serving GW) or a packet data network gateway (PDN GW) as an example in the process of a terminal attaching to an LTE network to further illustrate the present invention. In order to make the diagram concise and concise, the forwarding network elements and related scenarios that have no influence on the transmission of key parameters are ignored in the diagrams of this embodiment, such as roaming, handover, idle, etc., but it should be understood that these can exist in the actual environment . The following uses several application scenarios as examples for further illustration.

[0088] Such as image 3 As shown, the terminal UE obtains the ePDG IP address information (the ePDG IP address list is taken as an example in this embodiment) from the packet data network gateway (that is, the ePDG IP address information is configured on the packet data ne...

Embodiment 3

[0210] In this embodiment, the LTE network communication device is used as a mobile management entity (MME), a serving gateway (Serving GW) or a packet data network gateway (PDN GW). The IP address is passed to the terminal as an example, for an example description, see Figure 10 shown, including:

[0211] Step 1001, the terminal attaches to the LTE network, and establishes sessions with MME, Serving GW, and PDN GW;

[0212] Step 1002, the packet data network gateway sends a creation bearer request message to the service gateway, and carries the ePDG IP address list configured on the packet data gateway in the message;

[0213] Step 1003, the serving gateway sends a create bearer request message to the mobility management entity, and carries the ePDG IP address list sent by the packet data gateway in step 1002;

[0214] Step 1004, the mobility management entity sends a bearer establishment request / session management request message to the base station, and carries the ePDG ...

Abstract

The invention discloses a WIFI voice service initiation method for LTE communication equipment, a terminal and a communication system. First, the IP address information of the evolved packet data gateway is preset on the LTE network communication equipment; The packet data gateway IP address information is passed to the terminal; then the terminal establishes a communication connection with the corresponding evolved packet data gateway in the WiFi network according to the evolved packet data The packet data gateway initiates the WIFI voice service; that is, the terminal in the present invention does not rely on the deployment of DNS equipment, and can directly discover the evolved packet data gateway through the LTE network. The method is simple and the efficiency of finding the evolved packet data gateway is high, which can speed up the terminal With the speed of the evolved packet data gateway, the network deployment of the WiFi voice service (ie VoWiFi service) is more open, which can improve the satisfaction of the user experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for initiating a WIFI voice service, an LTE communication device, a terminal and a communication system. Background technique [0002] WiFi (Wireless Fidelity) is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as Pads and mobile phones) to each other. WiFi is a brand of wireless network communication technology, owned by the WiFi Alliance (Wi-Fi Alliance). The purpose is to improve the interoperability between wireless network products based on the IEEE802.11 standard. [0003] WiFi was originally the abbreviation of wireless fidelity. The full English name of WiFi is Wireless Fidelity. In the category of wireless local area network, it refers to "wireless compatibility certification". To connect to the network; the common one is a wireless router, so in the effective range of the radio wave coverage of this wireless r...
