Specific embodiment explain in detail.
Referring to Fig.1, the embodiment of the invention provides a kind of wireless communications method, the method may include following steps:
Step 11, when receiving the first access request of user terminal transmission, judge current network-like of 5G core net
Whether condition meets preset network condition.
Wherein, in first access request include: communication request that the user terminal is communicated with 5G core net.
In specific implementation, the communication request can be registration request, or service request.When the communication is asked
When asking as registration request, UE, not in 5G core over-network registration, triggers UE by the registration request before sending the first access request
Registration is completed in 5G core net.When the communication request is service request, UE before sending the first access request it is usual
In 5G core over-network registration, related service is handled by service request triggering 5G core net.
In specific implementation, UE can send the first access request to base station in several ways, for example, UE is connecing at random
After entering successfully, first access request can be carried by being sent to the RRC connection setup complete message of base station.It needs
Bright, base station can not directly be parsed comprising registration request or service request NAS message, and UE needs have been established in RRC connection
At the first access request i.e. NAS message of 5G is indicated in message, then base station just can know that UE expects the core of access 5G
Net.It is, of course, also possible to send the first access request to base station using other way, no longer illustrate one by one herein.
In specific implementation, can according to load of link etc. between the load of 5G core net, 5G core net and base station because
The first network condition is arranged in element.For example, it is 5G core net load lower than 90% that the first network condition, which can be set, or
The load of link is lower than 90% between person 5G core net and base station.
In specific implementation, the communication request of UE is different, and different first network conditions can be set, phase also can be set
Same first network condition, specifically with no restriction.For example, when the communication request of UE is registration request and service request, it can be with
Identical first network condition is arranged with the bearing capacity of 5G core net.
In specific implementation, base station receive user terminal transmission the first access request when, can by with 5G core
Signalling exchange between heart net, knows whether the current Network status of 5G core net meets first network condition.It is of course also possible to
Judge whether the current Network status of 5G core net meets first network condition using other detection means.
Step 12, when the current Network status of 5G core net does not meet default first network condition, adjustment and the use
The core net that family terminal is communicated, so that the user terminal is communicated with core net adjusted.
In specific implementation, base station can adjust the core net communicated with UE using various ways, so that the UE
It can be communicated with core net adjusted.
In one embodiment of this invention, when only including that UE is communicated with 5G core net in first access request
When communication request, base station can send the instruction information that 5G core net can not access to the UE, can also send access 4G core

Heart net initiates access, i.e. transmission 4G non-access layer information.
In specific implementation, base station can send the instruction information that 5G core net can not access to UE using various ways,
Specifically with no restriction.Believe for example, base station can send the instruction that 5G core net can not access to UE by RRC connection release message
Breath, and indicate that 5G core net can not access by newly-increased release cause.UE can the RRC between release and base station connect it
Afterwards, then to 4G core net it initiates to access.Base station can also send 5G core net to UE by the RRC signaling newly introduced and can not access
Instruction information, avoid in the process release RRC connection.
In specific implementation, UE can initiate to access using various ways to 4G core net, specifically with no restriction.
In one embodiment of this invention, UE can be by sending the wireless connection of first access request to 4G core
Net initiates access.That is, UE can keep the wireless connection between base station when initiating to access to 4G core net, and
