Detailed Description
Currently, when a UE needs to initiate a service, such as accessing a network, making a call, etc., a Radio Resource Control (RRC) connection needs to be established with a base station, and then an NAS (Non-Access Stratum) message is sent to the base station, the base station delivers the NAS message to a corresponding core network, and the core network performs authentication for the UE, configures a bearer, etc.
When a 5G-capable UE attempts to access the 5G core network through a 4G base station that can simultaneously connect to both the 4G core network and the 5G core network, the UE sends an RRC connection request to the 4G base station in message 3 of random access (MSG3) after initiating random access. After the random access is successful, the 4G base station sends an RRC connection establishment message, wherein the RRC connection establishment message comprises configuration information of a signaling radio bearer.
After receiving the RRC connection setup request, the UE establishes an RRC connection using the configuration therein, then sends an RRC connection setup complete message to the 4G base station, and carries a 5G NAS signaling in the RRC connection setup complete message, where the NAS signaling may be a service request or a registration request.
When the 4G base station receives the RRC connection establishment completion signaling, if the 4G base station finds that the 5G network is overloaded at the moment, the 4G base station cannot select the 5G core network to send the received 5G NAS signaling to the 4G base station, and at the moment, the 4G base station can only reject the UE, so that the UE cannot smoothly carry out services.
In view of the above problems, in the wireless communication method provided in the embodiments of the present invention, when the current network condition of the 5G core network does not satisfy the preset first network condition, the base station adjusts the core network that communicates with the UE, so that the UE can communicate with the adjusted core network, and therefore, when the network condition of the 5G core network is not good, the UE can communicate with the network, and user experience is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a wireless communication method, which may include the following steps:
and step 11, when receiving a first access request sent by the user terminal, judging whether the current network condition of the 5G core network meets a preset network condition.
Wherein the first access request comprises: and the user terminal carries out a communication request of communication with the 5G core network.
In a specific implementation, the communication request may be a registration request or a service request. And when the communication request is a registration request, the UE is not registered on the 5G core network before sending the first access request, and the registration request triggers the UE to complete registration on the 5G core network. When the communication request is a service request, the UE usually registers on the 5G core network before sending the first access request, and the service request triggers the 5G core network to process the related service.
In specific implementation, the UE may send the first access request to the base station in multiple ways, for example, after the UE succeeds in random access, the UE may carry the first access request by an RRC connection setup complete message sent to the base station. It should be noted that the base station cannot directly parse the NAS message including the registration request or the service request, and the UE needs to indicate the NAS message of 5G, which is the first access request, in the RRC connection setup complete message, and then the base station can know that the UE expects to access the core network of 5G. Of course, the first access request may also be sent to the base station in other manners, which are not illustrated here.
In a specific implementation, the first network condition may be set according to a load of a 5G core network, a load of a link between the 5G core network and a base station, and the like. For example, the first network condition may be that the load of the 5G core network is lower than 90%, or the load of the link between the 5G core network and the base station is lower than 90%.
In a specific implementation, the UE may set different first network conditions according to different communication requests, or may set the same first network conditions, which is not limited specifically. For example, when the communication request of the UE is a registration request and a service request, the same first network condition may be set according to the bearer capacity of the 5G core network.
In specific implementation, when receiving a first access request sent by a user terminal, a base station may learn whether a current network condition of a 5G core network meets a first network condition through signaling interaction with the 5G core network. Of course, other detection means may also be adopted to determine whether the current network status of the 5G core network satisfies the first network condition.
And step 12, when the current network condition of the 5G core network does not meet the preset first network condition, adjusting the core network which communicates with the user terminal, so that the user terminal communicates with the adjusted core network.
In a specific implementation, a base station may adjust a core network for communicating with a UE in various ways, so that the UE may communicate with the adjusted core network.
In an embodiment of the present invention, when the first access request only includes a communication request for the UE to communicate with the 5G core network, the base station may send, to the UE, indication information that the 5G core network cannot access, may also send indication information for accessing the 4G core network or indication information for reporting a 4G non-access stratum signaling, and the UE initiates access to the 4G core network according to the indication information, that is, sends a 4G non-access stratum message.
In a specific implementation, the base station may send, to the UE, indication information that the 5G core network cannot access in multiple ways, which is not limited specifically. For example, the base station may send, to the UE, indication information that the 5G core network cannot be accessed through an RRC connection release message, and indicate that the 5G core network cannot be accessed through an additional release reason. The UE may initiate access to the 4G core network after releasing the RRC connection with the base station. The base station can also send the indication information that the 5G core network cannot be accessed to the UE through the newly introduced RRC signaling, and the RRC connection is prevented from being released in the process.
In a specific implementation, the UE may initiate access to the 4G core network in a variety of ways, and is not limited in particular.
In an embodiment of the present invention, the UE may initiate access to the 4G core network through the radio connection sending the first access request. That is, when initiating access to the 4G core network, the UE may maintain a radio connection with the base station and initiate access to the 4G core network using the radio connection.
In another embodiment of the invention, the UE may initiate access to the 4G core network over the re-established radio connection. That is, when initiating access to the 4G core network, the UE may first release the radio connection established with the base station when sending the first access request, reestablish the radio connection with the base station, and then initiate access to the 4G core network using the reestablished radio connection.
It can be understood that, when the communication request included in the access request when the UE initiates access to the 4G core network is a service request, if the UE is not registered on the 4G core network, the UE needs to register on the 4G core network first and then send a corresponding service request to the 4G core network.
In a specific implementation, after receiving the indication information that the 5G core network cannot be accessed, the UE may send a corresponding access request to the base station again, where the request carries a communication request for communicating with the 4G core network, that is, a 4G non-access stratum message. After receiving the access request, the base station sends the access request to a 4G core network, and the 4G core network provides service for the UE.
In another embodiment of the present invention, the first access request may include, in addition to a communication request for the UE to communicate with the 5G core network: the UE communicates with the 4G core network, and the purpose of the communication request communicating with the 4G core network may be the same as or different from that of the communication request communicating with the 5G core network, even if the two communication requests have the same purpose, for example, both the two communication requests may be a service request or a registration request, but the content in the message carrying the two communication requests may be different.
For example, the first access request may include a service request of the UE to the 4G core network and a service request of the 5G core network at the same time, or include a registration request of the UE and the 5G core network and a registration request of the 5G core network at the same time.
In a specific implementation, after obtaining the two communication requests carried in the first access request, the base station may select a suitable core network to serve the UE according to actual load conditions of the 4G core network and the 5G core network.
Specifically, when the current network condition of the 5G core network does not satisfy the first network condition, the base station may send, to the 4G core network, a communication request for communicating with the 4G core network, which is included in the first access request, and the 4G core network processes the communication request of the UE.
The base station may send, when the current network condition of the 4G core network does not satisfy the preset second network condition, the communication request for communicating with the 5G core network, which is included in the first access request, to the 5G core network, and the 5G core network processes the communication request of the UE.
When the current network conditions of the 4G core network and the 5G core network do not satisfy the corresponding network conditions, the base station may send an RRC connection release message to the UE to release the RRC connection with the UE.
When the current network conditions of the 4G core network and the 5G core network both satisfy the corresponding network conditions, the base station may randomly select a core network for communicating with the UE and send the corresponding communication request to the selected core network, or may preferentially select the 5G core network as the core network for communicating with the UE and send the corresponding communication request to the 5G core network.
In a specific implementation, the second network condition may be set according to a load of the 4G core network, a load of a link between the 4G core network and the base station, and the like. For example, the second network condition may be set to be that the load of the 4G core network is lower than 90%, or the load of the link between the 4G core network and the base station is lower than 90%.
The UE may set different second network conditions or set the same second network conditions according to different communication requests, which is not limited specifically. For example, when the communication request of the UE is a registration request and a service request, the same second network condition may be set according to the bearer capacity of the 4G core network.
In a specific implementation, when the base station determines that the current network condition of the 5G core network meets a preset first network condition, the base station may send a communication request, which is carried in the first access request and communicates with the 5G core network, to the 5G core network, and the 5G core network may process the communication request.
As can be seen from the above, in the wireless communication method in the embodiment of the present invention, when the current network status of the 5G core network does not satisfy the preset first network condition, the base station may adjust the core network that communicates with the UE, so that the UE may communicate with the adjusted core network, and therefore, when the network status of the 5G core network is not good, the UE may communicate with the network, thereby improving user experience.
