The Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (eNB or e-NodeB) and a 5G Base Station (gNB) in LTE.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of an indication method of emergency services according to an embodiment of the present invention. The method is applied to a terminal device, and as shown in fig. 1, the method includes:

step 110, receiving a registration acceptance message, wherein the registration acceptance message includes indication information related to the emergency service, and the indication information related to the emergency service is carried by 1 bit;

step 120, when the terminal device accesses to the 5G core network through an evolved universal mobile telecommunications system terrestrial radio access network E-UTRAN cell or through a 5G wireless new air interface cell, and the indication information related to the emergency service indicates that the network supports an IP Multimedia Subsystem (IMS) -based emergency service, determining a request type of the emergency service provided by the network as an initial emergency request;

step 130, sending a request message for establishing a Protocol Data Unit (PDU) session for emergency service, where the request message includes an initial emergency request.

In an implementation manner of this embodiment, the emergency service may be different types of services such as an emergency call, and this embodiment is not limited in this embodiment.

In an implementation manner of this embodiment, the terminal device may first apply for registration to the network after being powered on, and the network may feed back a registration acceptance message to the terminal device after receiving a registration request sent by the terminal device. The terminal device may register to the 5G core network through an E-UTRAN cell or a 5G radio access network (NG-RAN), and a detailed specific registration procedure will not be described in detail in this embodiment, where the embodiment is not limited to a specific registration procedure.

In an implementation manner of this embodiment, the registration request (registration accept) message only includes one indication information related to the emergency service, and this embodiment specifically defines the indication information related to the emergency service, so that the above contents in this embodiment can be implemented. Specifically, the emergency service-related indication information is carried by one bit. And the indication information related to the Emergency service supports the Emergency service based on the IP multimedia subsystem IMS, i.e. the Emergency Services via IMS Support indicator (value 1) is indicated by 1 bit.

For the terminal device, after receiving the registration acceptance message, after parsing the indication information related to the emergency service therein, if the terminal device accesses a 5G Core Network (5G Core Network,5GC) through an E-UTRAN cell or through a 5G wireless new air interface cell, the terminal device may directly determine that the request type of the emergency service provided by the Network is an initial emergency request ".

After the terminal device determines that the initial emergency request is "initial emergency request", it may initiate request information of PDU session, that is, the terminal device initiates PDU session initiation for emergency service, and at the same time, the terminal device may set the request type IE in the request information to "initial emergency request".

After receiving the request information of the PDU session, the network may establish a corresponding session connection.

Therefore, the embodiment can realize the authentication service process between the network and the terminal equipment by one bit, thereby facilitating communication.

It should be noted that the above method is particularly applicable to regions including countries such as china. However, in some areas such as the united states, since these areas are UE-based solutions, the network needs to provide three indications in total, namely, three bits, including an error service Support indicator for E-UTRA connection to 5GC, an error service Support indicator for NR-Radio, and an error service Support indicator using fault. In order to simplify the process of implementing emergency service by the terminal device, as shown in fig. 2, this embodiment further provides another emergency service indication method, where the method is applied to the terminal device, and the method includes:

step 210, receiving a registration acceptance message, where the registration acceptance message includes three indication information related to the emergency service, where each indication information related to the emergency service is carried by 1 bit;

step 220, determining the emergency service type supported by the network according to two of the three indication information related to the emergency service;

step 230, determining a request type of the emergency service according to the emergency service type;

step 240, a request message for establishing a PDU session for emergency service is sent, where the request message includes a request type.

In the embodiment of the invention, the registration acceptance message received by the terminal equipment from the network comprises three pieces of indication information related to the emergency service, and each piece of indication information related to the emergency service is carried by 1 bit; the terminal device can determine the emergency service type supported by the network according to two of the three indication information related to the emergency service, and determine the request type of the emergency service according to the emergency service type, that is, the terminal device can determine the request type of the emergency service only by two bits, and implement the emergency service with the network, thereby simplifying the process of implementing the emergency service by the terminal device.

In an implementation manner of this embodiment, step 230 may be specifically implemented as:

when the terminal equipment accesses the 5G core network through the E-UTRAN cell, and the first indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the emergency service based on the IMS, and the second indication information related to the emergency service in the three indication information related to the emergency service indicates that the network does not support the fallback emergency service connected to the 5G core network based on the E-UTRA cell, the request type is determined to be an initial emergency request.

In another implementation manner of this embodiment, step 230 may be specifically implemented as:

when the terminal equipment accesses the 5G core network through the E-UTRAN cell, and the first indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the emergency service based on the IMS, and the second indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the fallback emergency service connected to the 5G core network based on the E-UTRA cell, determining that the request type is the fallback type emergency service.

After receiving the registration acceptance message, if the terminal equipment accesses the 5G core network through the E-UTRAN cell, the terminal equipment directly determines two of three indication information related to the emergency service in the registration acceptance message, and determines the emergency service type supported by the network according to the two indication information related to the emergency service. That is, it is determined whether the first emergency service-related indication information indicates whether the network supports the IMS-based emergency service, and it is determined whether the second emergency service-related indication information indicates that the network supports the fallback emergency service for connecting to the 5G core network based on the E-UTRA cell.

The terminal device may determine the following two situations:

the first case is: the first emergency service-related indication information indicates that the network supports an IMS-based emergency service, and the second emergency service-related indication information indicates that the network does not support a fallback emergency service for connecting to a 5G core network based on an E-UTRA cell. Namely, the expression Services via IMS Support indicator is 1, and the expression Services Support indicator uses feedback for E-UTRA connection to 5GC is 0.

The second case is: the first emergency service-related indication information indicates that the network supports an IMS-based emergency service, and the second emergency service-related indication information indicates that the network supports a fallback emergency service for connecting to a 5G core network based on an E-UTRA cell. Namely, the expression Services via IMS Support indicator is 1, and the expression Services Support indicator uses feedback for E-UTRA connection to 5GC is 1.

For the first case, the terminal device may determine that the request type is the initial emergency request ".

For the second case, the terminal device may determine that the request type is the fallback type Emergency Services fallback.

when the terminal equipment accesses a 5G core network through a 5G wireless new air interface cell, and a first indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the emergency service based on the IMS, and a second indication information related to the emergency service in the three indication information related to the emergency service indicates that the network does not support the fallback emergency service based on the wireless new air interface, determining that the request type is an initial emergency request.

when the terminal equipment accesses a 5G core network through a 5G wireless new air interface cell, and a first indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the emergency service based on the IMS, and a second indication information related to the emergency service in the three indication information related to the emergency service indicates that the network supports the fallback emergency service based on the wireless new air interface, the request type is determined to be the fallback type emergency service.

After receiving the registration acceptance message, if the terminal device accesses the 5G core network through the 5G wireless new air interface cell, the terminal device directly determines two of three indication information related to the emergency service in the registration acceptance message, and determines the emergency service type supported by the network according to the two indication information related to the emergency service. That is, it is determined whether the first emergency service-related indication information indicates that the network supports the IMS-based emergency service, and it is determined whether the second emergency service-related indication information indicates that the network supports the fallback emergency service based on the wireless new air interface.

The terminal device may determine the following two situations:

the third case is: the first emergency service-related indication information indicates that the network supports the IMS-based emergency service, and the second emergency service-related indication information indicates that the network does not support the fallback emergency service based on the wireless new air interface. Namely: the information service via IMS Support indicator is 1, and the information service Support indicator uses feedback for NR-Radio is 0.

The fourth case is: the first emergency service-related indication information indicates that the network supports the IMS-based emergency service, and the second emergency service-related indication information indicates that the network supports the fallback emergency service based on the wireless new air interface. Namely: the information service via IMS Support indicator is 1, and the information service Support indicator uses feedback for NR-Radio is 1.

For the third case, the terminal device may determine that the request type is the initial emergency request ".

For the fourth case, the terminal device may determine that the request type is the fallback type Emergency Services fallback.

As can be seen from the above, although the registration acceptance message received by the terminal device includes three pieces of indication information related to the emergency service, the terminal device only needs to determine two of the three pieces of indication information, and does not need to logically determine the three pieces of indication information related to the emergency service, thereby simplifying the process of implementing the emergency service.

Fig. 3 is a flowchart of an indication method of emergency service according to still another embodiment of the present invention. The method is applied to a network device, and as shown in fig. 3, the method includes:

step 310, determining indication information related to the emergency service, wherein the indication information related to the emergency service indicates that the network supports the emergency service based on the IP multimedia subsystem IMS, and the indication information related to the emergency service is carried by 1 bit;

step 320, sending a registration acceptance message, where the registration acceptance message carries indication information related to the emergency service, and the registration acceptance message is used for enabling the terminal device to determine that the request type of the emergency service is an initial emergency request.

The above specific implementation may be combined with specific contents in the emergency service indication method in fig. 1 in this embodiment, and details are not described herein again in this embodiment.

Fig. 4 is a flowchart of an indication method of emergency service according to still another embodiment of the present invention. The method is applied to a network device, and as shown in fig. 4, the method includes:

step 420, sending a registration acceptance message, where the registration acceptance message carries three indication information related to the emergency service, where the registration acceptance message is used to enable the terminal device to determine a request type of the emergency service according to the emergency service type supported by the network determined by two of the three indication information related to the emergency service.
