Embodiment 1

[0081] Such as figure 1 As shown, the flow chart of the emergency number configuration method provided in Embodiment 1 of the present application includes the following steps:

[0082] S101: After the user terminal UE accesses the wireless local area network, the network side device determines the location information of the UE.

[0083] The emergency number configuration method provided by the embodiment of the present invention is applied to the network side equipment, the network side equipment is mainly a gateway equipment, but does not exclude other equipment, such as router equipment, switch equipment, etc., for the core idea of ​​the present invention, the gateway equipment The advantages of the present invention can be fully utilized, but the gateway is not the only manifestation of the present invention. For example, after the UE accesses the wireless local area network, the emergency call service is enabled based on VoWiFi, and the gateway device may be an ePDG (Evo...

Embodiment 2

[0090] In order to improve the efficiency of obtaining the list of emergency numbers, on the basis of the above-mentioned embodiments, in the embodiments of the present application, such as figure 2 As shown, the flow chart of the emergency number configuration method provided in Embodiment 2 of the present application includes the following steps:

[0091] S201: After the user terminal UE accesses the wireless local area network, the packet data gateway ePDG determines the location information of the UE; wherein, the ePDG is pre-configured with emergency number lists corresponding to different geographic locations.

[0092] In a specific implementation, after the UE accesses the wireless local area network, it will send a connection request message to the ePDG, and the connection request message includes the IP address information of the UE. Here, the IP address information of the UE is automatically assigned by the network side device when the UE accesses the wireless local...

Embodiment 3

[0106] On the basis of the above-mentioned embodiments, in the embodiment of the present application, after the UE accesses the WLAN, it will send a connection request message to the ePDG. The connection request message may also contain the location information of the UE. When the ePDG receives the UE After the connection request message including the location information of the UE is sent, the location information may be determined as the current location information of the UE. Moreover, after receiving the connection request message sent by the UE, the ePDG will also send a connection response message to the UE to notify the UE that the communication channel has been successfully established. Subsequently, the UE and the ePDG can complete the authentication process based on the established communication channel.

[0107] In addition, in the embodiment of the present application, the authentication request message sent by the UE to the ePDG may also include UE information, an...

Abstract

This application relates to the field of network technology, in particular to a method and device for configuring and obtaining emergency numbers to solve the problem that the existing emergency number configuration scheme cannot adapt to the roaming of terminal equipment; the emergency number provided by the embodiment of this application The configuration method includes: after the user terminal UE accesses the wireless local area network, the network side device determines the location information of the UE; and sends the emergency number list corresponding to the location information of the UE to the UE.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for configuring and obtaining an emergency number. Background technique [0002] With the rapid development of long-term evolution (Long Term Evolution, LTE) coverage and the widespread popularity of wireless connection (WIreless-FIdelity, WiFi) access, the means for operators to provide voice services has changed from the previous single circuit switching (Circuit Switch, CS ) Domain voice is extended to multi-access voice such as LTE, WiFi, and CS. Regardless of which method a user uses to make a voice call service, the emergency call service is one of the important services that operators must provide. Therefore, a WiFi-based voice (Voice over WiFi, VoWiFi) service also needs to provide users with an emergency call service. [0003] Currently, the VoWiFi service is established based on an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS). I...
