Detailed Description
In order to make the technical solution of the present invention clearer and more obvious, the solution of the present invention is further described below by referring to the drawings and examples.
It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of an embodiment of a network service implementation method according to the present invention. As shown in fig. 1, the following detailed implementation is included.
In 101, the UE obtains a supporting situation of a network side for a network service, including: NG-RAN support case for network traffic and 5GC support case for network traffic.
In 102, if the UE determines that the handover condition is satisfied according to the support of the network side for the network service, the UE initiates a handover procedure to complete the handover.
The UE can obtain the support situation of the network side for the network service sent by the AMF in the registration procedure.
Specifically, the UE may initiate a registration procedure to the NG-RAN, so that the NG-RAN reports its support for the network service to the AMF, and further, the UE may obtain the support for the network service from the network side returned by the AMF.
Fig. 2 is a schematic diagram of a registration process according to the present invention.
As shown in fig. 2, in step 3, the NG-RAN may send a Registration Request (Registration Request) message to the amf (new amf), which may carry the support of the NG-RAN for network traffic.
In step 22, the AMF sends a Registration Accept (Registration Accept) message to the UE, which may carry a support situation of the network side for the network service.
The AMF acquires the support situation of the NG-RAN for the network service reported by the NG-RAN and knows the support situation of the AMF for the network service, namely the support situation of the 5GC for the network service, and then the support situation of the network side for the network service can be returned to the UE by combining the support situations of the NG-RAN and the 5GC for the network service.
The network side support for network traffic may include:
1) only 5GC support, i.e. 5GC support but not NG-RAN support;
2) neither 5GC nor NG-RAN support;
3)5GC and NG-RAN support, etc.
For the network service, if the case belongs to case 1) or 2), the UE may determine that the handover condition is satisfied, and then may initiate a handover procedure for the network service, and if the case belongs to case 3), the network service may be processed in a normal manner without handover.
In the flow shown in fig. 2, except that the steps 3 and 22 need to carry their respective contents, the specific implementation of the other steps is the prior art.
In the switching process of the network service, the UE may initiate a service request for switching to the AMF, so that the AMF obtains switching decision information, where the switching decision information may include a support condition of the network side for the network service, and determines a switching manner according to the switching decision information, and completes the switching according to the switching manner.
Fig. 3 is a schematic diagram of a handover procedure according to the present invention.
As shown in fig. 3, the UE sends a Service Request (Service Request) to the AMF, where a network Service identifier may be carried, and if the network Service is an emergency Service, the network Service identifier may be carried.
According to the network service identification, the AMF can know which network service the UE initiates handover to, and can send an N2 Request (N2 Request for HO) message for handover to the NG-RAN, the NG-RAN can select a proper eNB for the UE according to the environment of the UE, the signal quality and the like, carry the eNB identification and the like in a handover command (HO Required), return the eNB identification and the like to the AMF, and inform the AMF of handover and the like.
And then, the AMF can determine a switching mode according to the acquired switching judgment information and complete switching according to the determined switching mode.
The handover decision information may include the network side support for the network service, i.e., the NG-RAN support for the network service and the 5GC support for the network service.
Since the UE initiates the handover procedure, the AMF may determine that it is not the case that both the NG-RAN and the 5GC support the network service, but the case that the 5GC supports the network service is known, so the AMF may analyze the supporting case of the NG-RAN for the network service, such as: if the 5GC supports network traffic, the NG-RAN does not support the network traffic.
If the 5GC supports network traffic and the NG-RAN does not support network traffic, the AMF may use a radio access technology handover (RAT HO) mode in which the core network 5GC remains unchanged but the base station needs to be changed, e.g., from the gbb to the eNB, and the NG-RAN may include both the gbb and the eNB, which may be connected to the 5GC, and may be connected to the 5GC through the gbb in general.
If the 5GC does not support network services, the AMF may use a packet switched domain System handover (PS System HO) mode in which both the core network and the base station are changed, such as being capable of handover to a 4G network.
The handover decision information may further include subscription information in addition to the support of the network side for the network service.
The AMF may acquire subscription information of the UE from a user data management device (UDM) through a Location Update Procedure (Update Location Procedure) of step 14 shown in fig. 2.
Accordingly, the AMF may determine the handover mode in combination with the support condition of the network side for the network service and the subscription information.
For example, if the 5GC does not support the network service or the subscription information does not support the network service, a PS System HO handover may be used, and if the 5GC and the subscription information both support the network service but the NG-RAN does not support the network service, an RAT HO handover may be used.
In addition, the AMF may also adopt a circuit domain handover (CS HO) mode, for example, if the UE requests to switch the "emergency call" service to the 3G network, the CS HO mode may be adopted.
How the AMF performs handover to the prior art according to each handover mode.
Example two
In this embodiment, the AMF may complete handover for the UE according to a handover procedure initiated by the UE. And the switching process is initiated after the UE determines that the switching condition is met according to the acquired support condition of the network side for the network service. The supporting situation of the network side for the network service comprises the following steps: NG-RAN support case for network traffic and 5GC support case for network traffic.
Before completing handover for the UE according to a handover procedure initiated by the UE, the AMF may obtain, in a registration procedure shown in fig. 2, a support condition of the NG-RAN for the network service, which is reported by the UE after initiating the registration procedure to the NG-RAN.
As shown in fig. 2, in step 3, the NG-RAN may send a Registration Request message to the amf (new amf), which may carry the support of the NG-RAN for network traffic.
In step 22, the AMF sends Registration Accept message to the UE, which may carry the support situation of the network side for the network service.
The AMF acquires the support situation of the NG-RAN for the network service reported by the NG-RAN and knows the support situation of the AMF for the network service, namely the support situation of the 5GC for the network service, and then the support situation of the network side for the network service can be returned to the UE by combining the support situations of the NG-RAN and the 5GC for the network service.
The network side support for network traffic may include:
1) only 5GC support, i.e. 5GC support but not NG-RAN support;
2) neither 5GC nor NG-RAN support;
3)5GC and NG-RAN support, etc.
For the network service, if the case belongs to case 1) or 2), the UE may determine that the handover condition is satisfied, and then may initiate a handover procedure for the network service, and if the case belongs to case 3), the network service may be processed in a normal manner without handover.
In the handover procedure, the UE may send a service request to the AMF, where the service request may carry a network service identifier.
According to the network service identification, the AMF can know which network service the UE initiates switching, and can send an N2 Request for HO message to the NG-RAN, the NG-RAN can select a proper eNB for the UE according to the environment of the UE, the signal quality and the like, and return the eNB identification and the like carried in HO Qequered to the AMF, and inform the AMF of switching and the like.
And then, the AMF can determine a switching mode according to the acquired switching judgment information and complete switching according to the determined switching mode.
The handover decision information may include the network side support for the network service, i.e., the NG-RAN support for the network service and the 5GC support for the network service.
Since the UE initiates the handover procedure, the AMF may determine that it is not the case that both the NG-RAN and the 5GC support the network service, but the case that the 5GC supports the network service is known, so the AMF may analyze the supporting case of the NG-RAN for the network service, such as: if the 5GC supports network traffic, the NG-RAN does not support the network traffic.
If the 5GC supports network traffic and the NG-RAN does not support network traffic, the AMF may employ a RAT HO handover manner. If the 5GC does not support network services, the AMF can adopt a PS System HO switching mode.
The handover decision information may further include subscription information in addition to the support of the network side for the network service.
The AMF may acquire subscription information of the UE from the UDM through step 14 Update Location Procedure shown in fig. 2.
Accordingly, the AMF may determine the handover mode in combination with the support condition of the network side for the network service and the subscription information.
For example, if the 5GC does not support the network service or the subscription information does not support the network service, a PS System HO handover may be used, and if the 5GC and the subscription information both support the network service but the NG-RAN does not support the network service, an RAT HO handover may be used.
In addition, the AMF may also adopt a CS HO handover mode, for example, if the UE requests to handover the "emergency call" service to the 3G network, the CS HO handover mode may be adopted.
