After the UDM receives second request message, can be according to the UE signing informations of the UE information and storage, decision
It is no to issue first qos parameter to the AMF, when determining that needs issue first qos parameter to the AMF, executes and sent out to the AMF
Give the operation of first qos parameter.
In the concrete realization, the content for including according to the UE information is different, which may include following several
Any one of possible realization method of kind：
First way：The UE information includes UE ability informations, then when the UDM determines that the UE ability informations indicate that the UE has
Have the ability for accessing the 4G networks and the UE signing informations be when supporting the UE access 4G networks, determine to the AMF send this
One qos parameter.
Since the ability of different UE access networks is different, for example, some UE only have the ability of access 4G networks, but do not have
There is the ability of access 5G networks, and some UE may be i.e. with the ability for accessing 4G networks, it may have the ability of access 5G networks.
In embodiments of the present invention, it if the UE does not have the ability of access 4G networks, can not subsequently switch in 4G networks, this kind
In the case of, which need not issue the first qos parameter to the AMF.It therefore, should if the UE information includes UE ability informations
UDM needs the ability for judging whether the UE has access 4G networks according to the UE ability informations, if UE ability informations instruction should
UE has the ability for accessing the 4G networks, illustrates that the UE can be realized and is linked into the 4G networks.
In addition, in practical application scene, the UE signing informations of UE signatures may include a variety of, for example, the UE contracts
Information shows only to support UE access 5G networks, UE access 4G networks is not supported, alternatively, the UE signing informations show both to support
UE access 4G networks, and support UE access 5G networks.Wherein, when the UE signing informations show only to support UE access 5G nets
Network, when not supporting UE access 4G networks, which subsequently can not also switch in the 4G networks, and in that case, UDM also may be used
First qos parameter is not issued with selection to the AMF.
Therefore, which also needs to judge whether UE signing informations are supported in the UE access to 4G networks, if UE signing letters
Breath supports the UE access 4G networks, then the UDM is determined is sent to the AMF by first qos parameter.But if the UE is signed
About information does not support the UE access 4G networks, even if the UE ability informations indicate that the UE has the ability for accessing the 4G networks,
But the UDM will not issue first qos parameter to the AMF.So, it is possible to reduce the data volume that UDM is issued.
The second way：The UE information includes UE location informations, then when the UDM determines the corresponding position of UE location informations
