Description
Technical Field
The invention relates to the information management technology in the field of mobile communication, in particular to a method and a device for providing an emergency number for a terminal.
Background
A Wireless Fidelity (WiFi) network is a technology capable of wirelessly connecting terminals such as personal computers and handheld devices (e.g., pads and mobile phones) to each other. WiFi is in the category of Wireless Local Area Network (WLAN) and is referred to as "Wireless compatibility certification", which is essentially a commercial certification and is also a Wireless networking technology. Previously, people needed to connect computers through network cables to achieve networking, however, WiFi can achieve networking through radio waves. Among them, a wireless router is commonly used, and the wireless router can be networked in a WiFi connection manner within an effective electric wave coverage range emitted by the wireless router, and if the wireless router is connected with an Asymmetric Digital Subscriber Line (ADSL) or other internet access lines, the wireless router is also called a "hot spot".
The main advantage of WiFi is that it does not need wiring and thus fits well with the needs of mobile office users, and since the signal transmission power of the wireless router is lower than 100mw, i.e. lower than the transmission power of the handset, it is relatively the safest and healthier to access the internet via WiFi. Since the WiFi band is unlicensed worldwide, WLAN wireless devices provide an extremely inexpensive and data-bandwidth wireless air interface that is available worldwide.
Long term evolution (L)The ong term Evolution, LTE) network is a third generation (3)rdGeneration, 3G) mobile communication network, voice service is mainly implemented in a Circuit Switched Domain/Circuit bearer Domain (CS) under a 2G/3G network, whereas in an LTE fourth Generation (4G) mobile communication network, only a Packet Switched Domain/data Domain (PS) has no CS Domain. Therefore, the LTE mobile UE needs to adopt a Voice over LTE (VoLTE) technology based on the PS domain, so as to implement a Voice service based on the LTE 4G network. However, with the advent of terminals supporting Voice over WiFi (VoWiFi) services, VoWiFi has become an effective complement to VoLTE services and complies with standards set by the third Generation Partnership Project (3 GPP).
Emergency calls are a specific voice service function in mobile communication systems, even if the mobile terminal is set to limit outgoing calls and not plugged in a subscriber identity module (SIM card), as long as within the area covered by the mobile network, when the user dials an emergency number such as: 110. 119, the call is forwarded to a corresponding emergency call center such as a police station, a fire brigade and the like, and the operation of the whole emergency call system needs to be completed by the cooperation of a telecommunication operator and emergency service organizations such as police, fire fighting and the like. In a 3GPP LTE network, a Mobility Management Entity (MME) may send a local emergency number to a UE, and the UE stores the local emergency number and uses the local emergency number when an emergency call needs to be initiated; however, under VoWiFi, there is no method for the network side to provide the UE with the emergency number. Thus, if the UE preferentially accesses the WLAN, the emergency number cannot be acquired; and from the implementation process of part of the UE, even if the UE has ever accessed the LTE network, or the UE receives emergency numbers from the MME, the emergency numbers are not saved when the UE accesses the WLAN network again. Then, when the UE does not store the emergency number, the emergency number cannot be dialed by an emergency call, and thus the emergency call function cannot be implemented.

Detailed Description
Fig. 1 is a schematic diagram of a network structure for interworking between WLAN and LTE, and as shown in fig. 1, the network structure mainly includes:
user Equipment/terminal (UE): the method is used for accessing the WiFi/LTE network and VoWiFi/VoLTE service.
Evolved-Universal Radio Access Network (E-UTRAN): in a mobile communication radio network in LTE, the main network entities include enodebs.
Mobility Management Entity (MME): is responsible for managing and storing UE context (such as UE identity or user identity, mobility management status, user security parameters, etc.); allocating a temporary identifier for a user; when the UE is stationed in the tracking area or the network, the UE is responsible for authenticating the user; all non-access stratum messages between the MME and the UE are processed.
Home Subscriber Server (HSS): the user subscription data is permanently stored.
Serving Gateway (Serving GW): the S-GW is a user plane entity for short and is responsible for user plane data routing processing; and managing and storing the bearer context of the UE, such as IP bearer service parameters, network internal routing information and the like. The gateway is also an anchor point of the user plane in the 3GPP system, and one user only has one Serving GW at one time.
Packet Data Network Gateway (PDN GW): the PGW is responsible for a gateway of UE accessing PDN, allocates user IP address, and is also a mobility anchor point of 3GPP and non-3 GPP access systems. Furthermore, a user can access multiple PDN GWs at the same time.
Policy and Charging Rule Function (PCRF): the functional entity mainly generates a Quality of Service (Qos) rule and a charging rule for controlling user data transmission according to the Service information, the user subscription information and the configuration information of an operator. In addition, the functional entity may also control the establishment and release of bearers in the access network. The session between the PCRF and the PGW may be performed through a Gx interface, for example, the PCRF may obtain a local IP address of the UE from the PGW through the Gx interface.
Access Point (Access Point, AP): the core of the WLAN wireless network is equivalent to a bridge connected with a network and a wireless network, and the core of the WLAN wireless network is mainly used for connecting various wireless network clients together and then connecting the wireless network to the Ethernet.
3GPP Authentication Authorization Accounting Server (3GPP Authentication, Authorization, Accounting Server, 3GPP AAA Server): is responsible for authentication and subscription to the UE.
Evolved Packet Data Gateway (ePDG): an access gateway that is non-3 GPP and 3GPP interoperable; the UE accessed from the WLAN accesses to the ePDG through the SWu interface, then the ePDG establishes a session with the 3GPP AAA Server through the SWm interface to carry out authentication and subscription, and accesses to the PDN GW through the ePDG through the S2b non-trusted interface, thereby further using the resources of the LTE core network.
Internet protocol Multimedia Subsystem (IMS): the subsystem supporting the IP multimedia service provided by the 3GPP is characterized in that a Session Initiation Protocol (SIP) system is adopted, the communication is independent of the access mode, and the subsystem has multiple capabilities of separating the control function and the bearing capacity of multiple multimedia services, separating a call from a Session, separating an application from a service, separating the service from a network, fusing a mobile network with an Internet service and the like.
Here, the UE is connected to the E-UTRAN over an LTE-Uu interface; the E-UTRAN can be connected with MME through S1-MME interface, then MME is connected with HSS through S6a interface, E-UTRAN can also be connected with Serving GW through S1-u interface, then Serving GW is connected with PDN GW through S5/S8 interface; the MME is also connected with Serving GW through an S11 interface; the UE can also be connected with an ePDG through an SWu interface, the ePDG is connected with a 3GPP AAA Server through an SWm interface, or the ePDG is connected with a PDN GW through an S2b interface; the PDN GW can be connected with the PCRF through a Gx interface and can also be connected with the IMS through an SGi interface; the PCRF is connected with the IMS through an Rx interface.

step a: configuring emergency number related information;
step b: when it is determined that the emergency number is allowed to be provided to the terminal, the configured emergency number is read and transmitted to the terminal.
Here, the emergency number related information may be configured in the ePDG, the AAA Server, or a Proxy Call Session Control function (P-CSCF); the emergency number may be implemented in a form of an emergency number list in practical applications.
There are two different scenarios for the UE to acquire the emergency number: one is that the UE requests to acquire the emergency number in the WLAN network attachment process, and the other is that the UE requests to acquire the emergency number after the WLAN network attachment is successful. Correspondingly, the embodiment of the invention can have a plurality of modes for acquiring the emergency number: the UE acquires an emergency number from the ePDG in the WLAN network attachment process; or, the UE acquires the emergency number from the AAA Server in the WLAN network attachment process; or the UE acquires the emergency number from the ePDG after the WLAN network is successfully attached; or, the UE acquires the emergency number from the AAA Server after the WLAN network is successfully attached; or, after the WLAN network is successfully attached, the UE acquires the emergency number from the P-CSCF when registering to the IMS.
Based on the above-mentioned several ways of obtaining the emergency number, the following takes the implementation of the emergency number in the form of an emergency number list as an example, and details of the specific implementation flows of various methods for providing the emergency number for the terminal according to the present invention are described with reference to the accompanying drawings and specific embodiments.
