And/or a service type, determining, according to the device type and/or service type of the wireless terminal, whether the wireless terminal can register at the access node, and if so, the access node directly registers the wireless terminal without the wireless The registration request message of the terminal is sent to the core network device, and the wireless network device registers the wireless terminal.

2 is a schematic flowchart of a method for registering a wireless communication network according to Embodiment 1 of the present invention. As shown in FIG. 2, the executor of the local registration method in this embodiment is an access node, and the method includes:

S101: Receive a registration request message sent by the wireless terminal.

S103: determining, according to the device type and/or service type of the wireless terminal that is carried in the registration request message, whether to perform local registration on the wireless terminal; if it is determined to perform local registration on the wireless terminal, proceed to step S105;

S105: Register the wireless terminal according to a local registration configuration parameter.

The access node obtains the device type and/or service type of the wireless terminal carried in the registration request message, and determines whether to register the wireless terminal at the access node according to the device type and/or service type of the wireless terminal.

Specifically, the access node determines whether to register the wireless terminal at the access node according to the device type of the wireless terminal; or, the access node determines whether the wireless terminal is in the service type according to the wireless terminal The access node registers the wireless terminal; or the access node determines whether to register the wireless terminal with the access node according to the device type and service type of the wireless terminal.

If it is determined that the wireless terminal is locally registered, the access node does not need to forward the registration request message sent by the wireless terminal to the core network device, so that the core network device registers the wireless terminal, and the access node directly according to the local The configuration parameter registers the wireless terminal, wherein the local registration configuration parameter includes an authentication parameter and an encryption parameter and/or an integrity protection parameter, that is, the access node authenticates the wireless terminal according to the authentication parameter, according to the encryption parameter and/or Or the integrity protection parameter establishes a security mode for the wireless terminal and establishes a radio bearer with the wireless terminal.

In the embodiment of the present invention, the access node determines whether to locally register the wireless terminal according to the registration request message that is sent by the wireless terminal and that carries the wireless terminal device type and/or the service type. If it is determined that the wireless terminal is locally registered, the access terminal registers the wireless terminal without sending a registration request message to the core network device, and the core network device registers the wireless terminal, thereby greatly reducing the wireless terminal registration process letter. The overhead is reduced, and the registration delay of the wireless terminal is reduced.

Specifically, the core network device determines that the core network device is in a congestion state or an idle state according to the current load situation, where the congestion state indicates that the core network device current load is greater than a preset load threshold, and the idle state indicates that the core network device current load is not greater than a preset responsibility. Threshold. If the core network device is in a congested state, it is desirable to transfer the registration service of the wireless terminal to the access node as much as possible to reduce the burden on itself. Therefore, if the congestion notification message indicates that the core network device is in a congested state, the access is The node determines whether to perform local registration on the wireless terminal, and the wireless terminal capable of performing local registration is registered at the access node, alleviating the load pressure of the core network device, and reducing system signaling overhead. If the core network device is in an idle state, the core network device can accept the registration service of the wireless terminal. The access node forwards the registration request message to the core network device for the core network device to register with the wireless terminal.

FIG. 3 is a schematic flowchart diagram of another wireless communication network registration method according to Embodiment 1 of the present invention. As shown in FIG. 3, the executor of the local registration method in this embodiment is an access node, and the method includes:

S201: Receive local registration conditions delivered by the core network device.

Specifically, the access node receives the local registration condition delivered by the core network device in advance, where the local registration condition includes a device type and/or a service type that allows local registration to be performed. Further, the access node further receives the local registration configuration parameter delivered by the core network device in advance.

The local registration condition and the local registration configuration parameter may be directly sent by the core network device to the access node, or may be requested by the access node to the core network device, and then the core network device performs the request according to the access node. hair. The local registration conditions and the local registration configuration parameters can be delivered to the access node by the core network device at the same time. Further, the access node may receive the local registration condition and the local registration configuration parameter sent by the core network device, or the core network device directly configures the parameter of the access node by using the cloud platform or the software download mode. In this embodiment, the delivery mode and the delivery order of the local registration configuration parameters are not limited.

S203: receiving the registration request message sent by the wireless terminal, proceeds to step S205 or step S207 or step S209;

S205: determining whether the device type of the wireless terminal in the registration request matches the device type that is allowed to perform local registration in the local registration condition; if yes, proceeding to step S211; if not, sending the registration request message to the core network device for the core network The device registers the wireless terminal;

S207: determining whether the service type of the wireless terminal in the registration request matches the service type allowed to perform local registration in the local registration condition; if yes, proceeding to step S211; if not, Sending a registration request message to the core network device for the core network device to register with the wireless terminal;

S209: Determine whether the service type of the wireless terminal in the registration request matches the service type allowed to perform local registration in the local registration condition, and determine whether the device type of the wireless terminal in the registration request matches the device type allowed to perform local registration in the local registration condition. If yes, proceed to step S211; if not, send a registration request message to the core network device for the core network device to register with the wireless terminal;

S211: Register the wireless terminal according to a local registration configuration parameter.

Specifically, the access node receives the registration request message sent by the wireless terminal, where the registration request message carries the device type and/or service type of the wireless terminal. The access node determines whether to perform local registration on the wireless terminal according to the device type and/or service type of the wireless terminal in the registration request message and the local registration condition. There are three ways to determine, and one is to use one. The specific scheme is as follows:

1. If the device type of the wireless terminal in the registration request message matches the device type that is allowed to perform local registration in the local registration condition, the access node determines to perform local registration on the wireless terminal, and proceeds to step S211.

For example, the device type of the wireless terminal carried in the registration request message is "Voice Communication Type Device", and the value of the "Voice Communication Type Device" in the local registration condition is set to 0. Allowing the voice communication type device to perform local registration, the device type of the wireless terminal does not satisfy the local registration condition, and local registration is not performed on the wireless terminal.

The device type carried in the registration request message is "Vehicle Type Device", and the "Vehicle Type Device" value in the local registration condition is set to 1, indicating that the vehicle type device is allowed to perform local registration, then the The device type of the wireless terminal satisfies the local registration condition, and local registration can be performed on the wireless terminal.

2. If the service type of the wireless terminal in the registration request message matches the service type that is allowed to perform local registration in the local registration condition, the access node determines to perform local registration on the wireless terminal, and proceeds to step S211. .

For example, the service type of the wireless terminal carried in the registration request message is "Local Machine Type Communication", and the local registration condition is "local". The Local Machine Type Communication value is set to 1, indicating that the local machine device communication service is allowed to perform local registration, and the service type of the wireless terminal satisfies the local registration condition, and local registration can be performed on the wireless terminal.

The service type of the wireless terminal carried in the registration request message is “Voice Communication”, and the “Voice Communication” value in the local registration condition is set to 0, indicating that the voice call service is not allowed to perform local registration. The service type of the wireless terminal does not satisfy the local registration condition, and local registration is not performed on the wireless terminal.

3. If the service type of the wireless terminal in the registration request message matches the service type allowed to perform local registration in the local registration condition, and the device type of the wireless terminal and the local registration condition allow local execution The registered device types match, and the access node determines to perform local registration on the wireless terminal, and proceeds to step S211.

When the type of service performed by the wireless terminal satisfies the matching of the locally registered service type, the wireless terminal itself also needs to support the local registration. For example, the service type of the wireless terminal carried in the registration request message is “ultra-low latency service”, and the value of “ultra-low latency service” in the local registration condition is set to 1, indicating that the ultra-low delay service is allowed to perform local registration, if the registration request is If the device type of the carried wireless terminal does not support local registration, it is determined that local registration is not performed on the wireless terminal; if the device type of the wireless terminal carried in the registration request supports local registration, it is determined to perform local registration on the wireless terminal.

When the wireless terminal has multiple device types, the registration request message only carries the device type corresponding to the current service performed by the wireless terminal, for example:

When the wireless terminal is a mobile phone, the device types include "Voice Communication Type Device" and "Vehicle Type Device". When the mobile phone is used as a car navigation device or the car navigation service is turned on, The device type of the mobile phone corresponding to the car navigation service is "Vehicle Type Device", so only the "Vehicle Type Device" is carried in the local registration request message as the device type of the mobile phone. The mobile phone initiates the car navigation service, so the service type carried in the local registration request message is “ultra-low latency service”. The "Vehicle Type Device" value in the local registration condition is set to 1, indicating that the vehicle type device is allowed to perform local registration; the "ultra low latency service" value is set to 1, indicating that the ultra low delay service is allowed to perform local registration. This allows the phone to perform local registration.

In another embodiment, the registration request message further carries local registration indication information, where the local registration indication information is used to indicate whether the wireless terminal supports local registration, or whether the service requested by the registration supports local registration, or whether the wireless terminal desires to perform local registration. registered. The access node jointly determines whether to perform local registration on the wireless terminal according to the device type and/or service type of the wireless terminal in the registration request message, the local registration indication information, and the local registration condition. There are three ways to determine, and one is to use one. The specific scheme is as follows:

1. If the device type of the wireless terminal in the registration request message matches the device type that allows local registration in the local registration condition, and the local registration indication information indicates that the wireless terminal supports performing local registration, the access node determines to perform local registration on the wireless terminal. .

2. If the service type of the wireless terminal in the registration request message matches the service type allowed to perform local registration in the local registration condition, and the local registration indication information indicates that the wireless terminal supports performing local registration, the access node determines to perform local registration on the wireless terminal. .

3. If the device type of the wireless terminal in the registration request message matches the device type that is allowed to perform local registration in the local registration condition, the service type of the wireless terminal in the registration request message and the local registration condition allow the service type of the local registration to be matched, and The local registration indication information indicates that the wireless terminal supports performing local registration, and the access node determines to perform local registration on the wireless terminal.

In another embodiment, the access node receives the congestion notification message delivered by the core network device; if the congestion notification message indicates that the core network device is in a congested state, the access node continues to determine whether to perform local registration on the wireless terminal; The congestion notification message indicates that the core network device is in an idle state, and the access node forwards the registration request message to the core network device for the core network device to register with the wireless terminal.

In another embodiment, the specific registration process for the access node to register the wireless terminal according to the local configuration parameters is as follows:

First, the access node authenticates the wireless terminal according to the authentication parameter in the local registration configuration parameter. For example, the registration request message sent by the wireless terminal carries the wireless terminal authentication information, and the access node authenticates the wireless terminal according to the authentication parameter in the local registration configuration parameter and the wireless terminal authentication information carried in the registration request message. Or, the registration request message sent by the wireless terminal The access node supports the authentication mode supported by the wireless terminal, and the access node sends the authentication parameter to the wireless terminal according to the authentication mode supported by the wireless terminal, and authenticates the wireless terminal according to the authentication response value replied by the wireless terminal. Or the access node sends the authentication parameter in the local registration configuration parameter to the wireless terminal, and receives the authentication response value calculated by the wireless terminal returned by the wireless terminal according to the authentication parameter, and the access node performs wirelessly according to the authentication response value. The terminal performs authentication.

Further, the authentication parameter in the local registration configuration parameter further includes an access node authentication parameter for the wireless terminal to authenticate the network. The wireless terminal authenticates the access node according to the access node authentication parameter, and if the access node authentication parameter is incorrect, rejects the access node's authentication request; if the access node authentication parameter is correct, the wireless terminal Receiving an access node to authenticate the wireless terminal.

In another embodiment, if the authentication parameter in the local registration configuration parameter allows an access authentication mode of a non-wide area mobile communication system such as WLAN or Bluetooth, when the wireless terminal adopts a non-wide area mobile communication system such as WLAN or Bluetooth When the access mode accesses the access node, the access node may authenticate the wireless terminal by using an authentication method specified by a non-wide-area mobile communication system such as WLAN or Bluetooth.

In another embodiment, if the wireless terminal has been authenticated on another device authorized by the wireless communication network, such as a web server, or the wireless terminal acts as a group of devices (eg, Group of Machine Type Devices) The device in the device, the device group has been authenticated, and the registration request message sent by the wireless terminal carries the authentication indication information, and the access node determines the wireless terminal according to the authenticated indication information carried in the registration request message. No longer authenticated.

In another embodiment, if the registration request message sent by the wireless terminal carries the authentication-free indication information indicating that the wireless terminal does not perform authentication, the access node determines, according to the authentication-free indication information, that the wireless terminal is no longer authenticated. right.

The specific authentication method is not limited herein, and different authentication methods fall within the protection scope of the present application.

Then, after the access node authenticates the wireless terminal or determines that the wireless terminal is not authenticated, the access node establishes a security mode for the wireless terminal according to the encryption parameter and/or the integrity protection parameter in the local registration configuration parameter, that is, the wireless mode The terminal completes the encryption and integrity protection process, and the specific security The full mode establishment method is not limited herein, and different security mode establishment methods fall within the protection scope of the present application.

Finally, the access node establishes a radio bearer for the wireless terminal, that is, the access node allocates a radio bearer resource, and stores a radio terminal context (UE Context), and establishes a radio bearer with the radio terminal. Specifically, the access node sends a wireless terminal subscription data request to the core network device, requests to receive the subscription data of the wireless terminal, and determines the service quality of the wireless bearer according to the subscription data of the wireless terminal returned by the core network device, according to the determined wireless The quality of the service, the wireless terminal is allocated a wireless resource, the wireless bearer configuration information is generated, and the wireless bearer configuration information is sent to the wireless terminal, so that the wireless terminal establishes a wireless bearer according to the radio bearer configuration information and the access node. . Alternatively, the registration request response message sent by the core network device may also carry the subscription data of the wireless terminal, so that the access node acquires the subscription data of the wireless terminal by using the registration request response message.

In another embodiment, the access node may also establish a public bearer with the core network device before establishing the radio bearer for the wireless terminal, and the common bearer is not used for separately transmitting or receiving communication data of a certain wireless terminal, but Used to transmit or receive communication data of a plurality of wireless terminals served by the access node.

When the wireless terminal initiates a non-local service, that is, the peer wireless terminal does not belong to the current access node service, or the service request initiated by the wireless terminal needs to be processed by the core network, the public bearer is used to undertake the connection between the access node and the core network. Signaling interaction. That is, after the access node establishes a radio bearer for the radio terminal, the access node receives the uplink data sent by the radio terminal through the radio bearer established between the radio terminal and the wireless terminal, and then passes the radio bearer through the public bearer with the core network device. The uplink data is sent to the core network device, and the uplink data is sent by the core network device to the server or the peer wireless terminal. Or, the access node receives the downlink data sent by the core network device through the public bearer, and then sends the downlink data to the wireless terminal through the wireless bearer between the wireless terminal and the wireless terminal.

In another embodiment, if it is determined that local registration is not performed on the wireless terminal, the access node sends a registration request message to the core network device for the core network device to register with the wireless terminal.

The access node receives a registration request response message sent by the core network device to perform local registration on the wireless terminal, and registers the wireless terminal according to the local registration configuration parameter.

Optionally, the local registration configuration parameter may be pre-delivered to the access node by the core network device. Preferably, before the access node receives the registration request message sent by the wireless terminal, the core network device sends the local registration configuration parameter to the access. node.

Specifically, if the core network device sends the local registration configuration parameter to the access node in advance, the core network device notifies the access node to perform local registration on the wireless terminal by using the registration request response message after determining whether to perform local registration on the wireless terminal, The access node registers the wireless terminal according to the local registration configuration parameters.

If the core network device determines to perform local registration on the wireless terminal, the registration request response message carries a local registration configuration parameter, which is used to indicate that the access node is allowed to perform local registration on the wireless terminal. After receiving the registration request response message, the access node performs registration on the wireless terminal according to the local registration configuration parameter carried in the registration request response message.

Further, if the core network device determines that the local registration is not performed on the wireless terminal, the registration request response message does not carry the local registration configuration parameter, and is used to indicate that the access node is not allowed to perform local registration on the wireless terminal. After receiving the registration request response message, the access node checks whether the local registration configuration parameter is not carried in the registration request response message, and determines that the local registration is not performed on the wireless terminal.

Or, the registration request message sent by the wireless terminal carries the authentication mode supported by the wireless terminal, and the access node sends the authentication parameter to the wireless terminal according to the authentication mode supported by the wireless terminal, according to the authentication response value returned by the wireless terminal, The wireless terminal is authenticated. Or, the access node sends the authentication parameter in the local registration configuration parameter to the wireless The terminal receives the authentication response value calculated by the wireless terminal returned by the wireless terminal according to the authentication parameter, and the access node authenticates the wireless terminal according to the authentication response value.

Then, after the access node authenticates the wireless terminal or determines that the wireless terminal is not authenticated, the access node establishes a security mode for the wireless terminal according to the encryption parameter and/or the integrity protection parameter in the local registration configuration parameter, that is, the wireless mode The terminal completes the encryption and integrity protection process. The specific security mode establishment method is not limited herein. Different security mode establishment methods fall within the protection scope of the present application.
