In this way, the terminal can effectively perform an operation related to the service according to the above service instruction information.

[0048] Refer to FIG. 3. FIG. 3 is a flowchart of another service instruction method according to an embodiment of the present disclosure. This method is applied to a terminal. As shown in FIG. 3, it includes the following steps.

[0049] In step 301, the ability information of the service of the terminal is transmitted to a first network unit. The ability information indicates whether the terminal supports the service.

[0050] Here, the ability information of the service is transmitted in a login process, or a connection establishment process, or a service request process. The first network unit is made to confirm the ability of the terminal according to the ability information, and based on the terminal ability, the corresponding service instruction information can be confirmed.

[0051] ​​​​It should be noted that step 301 is optional. For example, the first network unit may Obtaining device capability information and setting the device to support the above services as default However, this is not a limitation in the embodiments of the present disclosure.

[0052] In step 302, service instruction information is obtained. The service instruction information is The service information includes at least one of support information for the service and trend information for the service. The services include at least one of an emergency service and a voice service.

[0053] Here, the service instruction information is received from the first network unit. For example, the terminal sends the above capability information through a login request message and becomes a first network user. The unit transmits a login acceptance message including the service instruction information to the terminal. Of course, the terminal sends a service request or a session establishment request for the above service to the first network unit. the first network unit sends a corresponding backoff message to the terminal. The backoff message may include the above-mentioned service instruction information and the like.

[0054] In step 303, the service is selected based on the acquired service instruction information. Perform related operations.

[0055] In an alternative embodiment, the service support information includes a service support instruction and a service The service support type information includes at least one of the service support type information.

[0056] Here, the service support instruction indicates whether or not the service is to be supported. For example, , NR (New Radio), eLTE or EPS (Evolved Packet When one or more of the systems support the service, the service support instruction can indicate whether to support the service in 1 bit by indicating support. This can simplify the process for the terminal to determine whether to start the service.

[0057] Here, the support for the service in the 5G system is made possible, although not limited to, by including at least one of the following. Method 1: In 5GS, the service (at least one of the emergency service and the voice service ) can be supported. For example, both NR and the 5G core network (5GC) can directly support the emergency service. Method 2: In the case of a QoS (Quality of Service) flow or PDU session established for the service (at least one of the emergency service and the voice service), E-UTRA (Evolved-UMTS Terrestrial Radio Access) is connected to the 5G core network (5GC) to support the service, and the 5G radio access network (NG RAN) can hand over the terminal to the E-UTRA connected to the 5GC. Method 3: In the case of a QoS flow or PDU session established for the service (at least one of the emergency service and the voice service), the 5G radio access network (NG RAN) can hand over the terminal to the EPS that supports the emergency session. Method 4: In the case of a QoS flow or PDU session established for the service (at least one of the emergency service and the voice service), the 5G radio access network ​ UE (NG RAN) triggers the terminal redirection to EPS to support the emergency session. To do so.

[0058] Thus, if supported in any way, the above service support indication (indicator) indicates to support the above service. For example, in one embodiment, when the NR is indicated to support the emergency service by the service type information, the service support information indication indicates to support the service.

[0059] For example, in one embodiment, when the eLTE is indicated to support the emergency service by the service type information, the service support information indication indicates to support the service. For example, in one embodiment, when the eLTE is indicated to support the emergency service by the service type information, the service support information indication indicates to support the service.

[0060] In one embodiment, when the service type information indicates that the eLTE does not support the emergency service and the NR also does not support the emergency service, but the network indicates to support the handover to EPS or the redirection to EPS, the service support information indication indicates to support the service. For example, taking TA (Tracking Area) and the emergency service as an example, it is shown in Table 1 and Table 2 below.

[0061] For example, taking TA (Tracking Area) and the emergency service as an example, it is shown in Table 1 and Table 2 below. And the NR also does not support the emergency service, but the network indicates to support the handover to EPS or the redirection to EPS, the service support information indication indicates to support the service. door over or the redirection to EPS, the service support information indication indicates to support the service.

[0062] For example, taking TA (Tracking Area) and the emergency service as an example, it is shown in the following Table 1 and Table 2.

[0063] [Table 1]

[0064] [Table 2]

[0065] Here, TA_NR = Y indicates that NR supports emergency services within TA, TA_eLTE = N indicates that eLTE does not support emergency services within TA, as described above TA_NR = N indicates that NR does not support emergency services within TA, and TA_eLT E = Y indicates that eLTE supports emergency services within TA.

[0066] In addition, the service support type information indicates at least one of whether the service can be supported by NR, whether the service can be supported by e LTE, whether the service can be supported by EPS, whether the service can be supported by handover to EPS, and whether the service can be supported by redirection to EP S. This enables indication with 3 bits, and each bit corresponds to any one of the NR service support instruction, eLTE service support instruction, and EPS service support instruction. This can save signaling overhead. Thus, the service support instruction indicates whether NR supports the service, whether e LTE supports the service, whether the service can be supported by handover to EPS, whether the service can be supported by redirection to EPS, whether the service can be supported by handover to EPS, and

[0067] at least one of whether the service can be supported by redirection to EPS. Here, when the service is supported by handover to EPS or redirected to EPS, by default, EPS provides the above service ​​​​​​It is intended to support the service. As a result, instructions can be given in 4 bits, and each bit corresponds to one of the following: NR emergency service support instruction, EPS handover support information, and EPS redirect support information. Specifically, each bit corresponds to either the NR emergency service support instruction, the EPS handover support information, or the EPS redirect support information. Of course, in one embodiment, the service support instruction indicates whether to support the service, and further indicates at least one of whether NR supports the service, whether eLTE supports the service, whether to support the service through handover to EPS, and whether to support the service through redirect to EPS. In this way, the terminal can confirm whether to support the above service or the method of supporting the above service, and can inform the user of how the emergency service is realized, eliminating the problem of impersonation.

[0068] Of course, in one embodiment, the service support instruction indicates whether to support the service, and further indicates at least one of whether NR supports the service, whether eLTE supports the service, whether to support the service through handover to EPS, and whether to support the service through redirect to EPS. That is, the terminal can confirm whether to support the above service or the method of supporting the above service, and can inform the user of how the emergency service is realized, eliminating the problem of impersonation. Of course, in one embodiment, the service support instruction indicates whether to support the service, and further indicates at least one of whether NR supports the service, whether eLTE supports the service, whether to support the service through handover to EPS, and whether to support the service through redirect to EPS. In this way, the terminal can confirm whether to support the above service or the method of supporting the above service, and can inform the user of how the emergency service is realized, eliminating the problem of impersonation. Of course, in one embodiment, the service support instruction indicates whether to support the service, and further indicates at least one of whether NR supports the service, whether eLTE supports the service, whether to support the service through handover to EPS, and whether to support the service through redirect to EPS. In this way, the terminal can confirm whether to support the above service or the method of supporting the above service, and can inform the user of how the emergency service is realized, eliminating the problem of impersonation. That is, the terminal can confirm whether to support the above service or the method of supporting the above service, and can inform the user of how the emergency service is realized, eliminating the problem of impersonation.

[0069] In addition, the above service support type information indicates the realization method of the service in the network. For example, the above service support type information indicates the type of supporting the service. Or, the above service support type information indicates at least one of whether the service can be supported by NR, whether the service can be supported by eLTE, and whether the service can be supported by EPS. Here, whether the service can be supported by EPS indicates at least one of whether it is possible to support the service by handing over the UE to EPS and whether it is possible to support the service by redirecting the terminal to EPS. That is, whether the service can be supported by EPS indicates at least one of whether it is possible to support the service by handing over the UE to EPS and whether it is possible to support the service by redirecting the terminal to EPS.

[0070] Here, whether the service can be supported by EPS indicates at least one of whether it is possible to support the service by handing over the UE to EPS and whether it is possible to support the service by redirecting the terminal to EPS. That is, whether the service can be supported by EPS indicates at least one of whether it is possible to support the service by handing over the UE to EPS and whether it is possible to support the service by redirecting the terminal to EPS. Here, whether the service can be supported by EPS indicates at least one of whether it is possible to support the service by handing over the UE to EPS and whether it is possible to support the service by redirecting the terminal to EPS.

[0071] In this embodiment, the service support type information is used to inform the user of how the above service is supported and how the emergency service is realized, so as to eliminate the problem of impersonation. The terminal is made to obtain it, and the user is informed of how the emergency service is realized. This can eliminate the problem of impersonation.

[0072] As an alternative embodiment, the service instruction information further includes instruction information for instructing whether to support the service by the back-off method. This instruction information may also be referred to as the instruction information for the service by the back-off method.

Of course, the service support information in step 302 may also include at least one of the service support information that does not adopt the back-off method and the instruction information for the service by the back-off method. Here, the service support information that does not adopt the back-off method indicates whether another method (which may also be referred to as a non-back-off method) other than the back-off method supports the above service. For example, it indicates whether the terminal directly supports starting the above service, whether to start the above service based on the scheduling on the network side, etc.

[0074] In this embodiment, by using the above instruction information for the service by the back-off method, it is realized to instruct the terminal whether to support the service by the back-off method. Thereby, the terminal can transmit the above service in the back-off method. Here, the service support information in step 302 may be the service support information that does not adopt the back-off method. Of course, the service support information in step 302 may also include at least one of the service support information that does not adopt the back-off method and the instruction information for the service by the back-off method.
