Fig. 2 is referred to, Fig. 2 is a kind of flow diagram for being wirelessly connected amending method provided by the embodiments of the present application, In the embodiment of the present application, the wireless heterogeneous networks connection between wireless access network node and terminal device is initiated by terminal device Modification.This method includes but is not limited to following steps:

S201, terminal device and wireless access network node establish wireless heterogeneous networks (Radio Resource Control, RRC it) connects.

For example, terminal device can be the terminal device 101 in Fig. 1.Wireless access network node can be the access in Fig. 1 Net node 102.

Terminal device carries out RRC with wireless access network node and connect establishment process.For example, terminal device is first to wireless access Net node sends RRC connection request message (RRC CONNECTION REQUEST), and RRC connection is established in request.Wireless access network RRC connection is established message (RRC CONNECTION SETUP) and is sent to terminal device by node, and terminal device is determining RRC company It connects after being successfully established, sends RRC connection setup complete message (RRC CONNECTION SETUP to wireless access network node COMPLETE), so that RRC connection establishment process terminates.

Optionally, in RRC connection establishment process, terminal device can send first network to wireless access network node Identification information.For example, may include the identification information of first network in RRC connection request message.The mark of the first network is believed Breath is used to indicate the first network that terminal device desires access to.First network is 5G core net in the embodiment of the present application, then The identification information of first network can be the mark of 5G core net.It should be noted that the identification information of first network is terminal A kind of identification information that equipment and wireless access network node can identify.

S202, terminal device initiate the registration of first network to wireless access network node.

After the completion of the RRC of terminal device and wireless access network node connection is established, the can be sent to radio access node Registration request (Registration Request) message of one network.Login request message is used to indicate wireless access network node The registration of first network is carried out for terminal device.Wherein, login request message be encapsulated in terminal device and radio access node it Between in specific message body, such as access internet message (Access Network message, AN message).

In a kind of possible design, if S201 establishes RRC connection, terminal device has sent to wireless access network node The identification information of first network, then terminal device sent to radio access node login request message when can not retransmit The identification information of first network.Because wireless access network node has passed through RRC, establishment of connection process has known terminal device The first network desired access to.

In alternatively possible design, if establish RRC connection in S201, terminal device is not to wireless access network section Point sends the identification information of first network, then terminal device can be simultaneously when sending login request message to radio access node Send the identification information of first network.The identification information of first network is used to indicate the first network that terminal device desires access to. By taking AN message as an example, the AN message that terminal device is sent to radio access node includes login request message and The identification information of one network, wireless access network node do not parse login request message and directly pass through the control in first network Veil member, meanwhile, wireless access network node passes through the available identification information to first network of AN message.Wherein, right For the embodiment of the present application, the control plane network element in first network refers to access and mobile management function to ps domain network element.For example, Access and mobile management function to ps domain network element can be the AMF network element 105 in Fig. 1.

That is, terminal device can send first network to wireless access network node during S201 and S202 Identification information, do not limit the message for carrying the identification information of the first network specifically, the identification information of first network can also be with It is individually carried in a message and is sent to wireless access network node.

It should be noted that RRC connection establishment process can also be regarded as a part of the registration process of first network.It can also To think, terminal device is exactly the mark of the first network sent in the registration process of first network to wireless access network node Information.

S203, wireless access network node select the access and movement in first network according to the identification information of first network Property management function network element.

The identification information of the first network sent in S201 or S202 indicates terminal device and needs to access 5G core net, because This wireless access network node can choose access in 5G core net and mobile management function to ps domain AMF network element to mention for terminal device For service.For example, access and mobile management function to ps domain network element can be access and mobile management function to ps domain AMF network element in Fig. 1 105.The specific choice method of AMF network element can determine suitable AMF net according to some information in login request message Member, such as determined according to mark, slice information of terminal device etc..

In the scene that a wireless access network node can be connect with two kinds of core nets simultaneously, wireless access network node is connect When receiving the signaling message of terminal device, it is not known which core net signaling message is sent to by this.The embodiment of the present application passes through Above-mentioned steps, in wireless heterogeneous networks connection establishment process or in the registration process of first network, terminal device is to wirelessly connecing Network access node sends the identification information of first network, and wireless access network node can be made to determine what terminal device currently desired access to Which network is, so that the correspondence network element of corresponding network be selected to execute follow-up process.

S204, wireless access network node send login request message to access and mobile management function to ps domain network element.

As described in S202, the login request message received is passed through the AMF network element selected by wireless access network node.

S205, access and mobile management function to ps domain network element are to above and below the uniform data managed network element initiating terminal of first network Text management registration (Nudm_UEContextManagement_Registration) service.

For example, uniform data managed network element can be the uniform data managed network element UDM network element 106 in Fig. 1.

The purpose of terminal contexts management registration service be will for terminal device service AMF network element registration to UDM network element In, that is to say, that so that UDM network element is saved as the relevant information of the AMF network element of terminal device service.For example, the phase of AMF network element Closing information includes the mark of AMF network element, user's permanent identification (SUPI, Subscription Permanent Identifier), At least one of in type (access type) of access technology etc..

Terminal contexts management registration service may include: that AMF network element is requested to the transmission terminal contexts management of UDM network element Message, AMF network element are registered according to terminal contexts management request and return to terminal contexts managing response message.

In the first possible design, in AMF network element initiating terminal context management registration service, end can be carried The mark of end equipment, can also carry the type of access technology, and UDM network element is according to the mark or UDM network element root of terminal device According to the mark of terminal device and the type of access technology, the terminal device can be inquired in the database and whether is contracted the first net The business of network.Wherein, database can be the database that subscription data is locally stored in UDM network element, be also possible to be exclusively used in saving The storage network element (for example, uniform data stores network element, Unified Data Repository, UDR) of subscription data.If eventually End equipment is not contracted the business of first network, then UDM network element can send the first instruction information to AMF network element, first refers to Show that information is used to indicate the business of the unsigned first network of terminal device.Optionally, UDM network element can also inquire terminal device Contracted the business of the second network, then the first instruction information can serve to indicate that the business of the unsigned first network of terminal device with And terminal device has been contracted the business of the second network.The first instruction information can be held by terminal contexts managing response message It carries.For example, original bit (for example, the bit for carrying cause value in existing standard) in terminal contexts managing response message In may include the first instruction information.Alternatively, may include in the instruction information increased newly in terminal contexts managing response message First instruction information.In this kind design, after AMF network element receives the first instruction information, no longer S206 can be executed and direct Execute S207.

In second of possible design, UDM network element in registration process is hereafter managed at the terminal and does not inquire terminal and sets The business of standby first network of whether contracting, will be only the AMF network element registration of terminal device service to UDM network element, then can be with Execute S206.

The uniform data managed network element initiating terminal equipment of S206, access and mobile management function to ps domain network element to first network Subscription data obtain (Nudm_SubscriberDataManagement_Get) service.

The purpose that subscription data obtains service is to obtain the corresponding subscription data of terminal device.Subscription data obtains service can To include: AMF network element to UDM network element transmission subscription data acquisition request message, UDM network element inquires the corresponding signing of terminal device Data, UDM network element return to subscription data to AMF network element and obtain response message.

If inquiring terminal device not contracting the business of first network, UDM network element can be sent to AMF network element First instruction information, the first instruction information are used to indicate the business of the unsigned first network of terminal device.Optionally, UDM network element Terminal device can also be inquired to have contracted the business of the second network, then it is unsigned to can be used for terminal device for the first instruction information The business and terminal device of first network have been contracted the business of the second network.The first instruction information can be obtained by subscription data Response message is taken to carry.For example, original bit is (for example, carry reason in existing standard in subscription data acquisition response message The bit of value carries) in may include the first instruction information.Alternatively, subscription data obtains the instruction letter increased newly in response message It may include the first instruction information in breath.And then AMF network element executes S207.

S207, access and mobile management function to ps domain network element send registration reject to terminal device according to the first instruction information Message.

Registration reject message is used to indicate the registration request failure of terminal device.Wherein, registration reject message may include The reason of being used to indicate the business of the unsigned first network of terminal device value.It is further alternative, if in S206 or S207 One instruction information further indicates terminal device and has contracted the business of the second network, then the reason value in registration reject message may be used also It has been contracted the business of the second network with being used to indicate terminal device.

For example, registration reject message can be passed through terminal device by wireless access network node by AMF network element.

S208, terminal device retain the radio resource control between wireless access network node and terminal device according to cause value System connection.

Terminal device retains wireless access network node and sets with terminal according to the reason value in the registration reject message received Wireless heterogeneous networks connection between standby, does not initiate the RRC Connection Release process between wireless access network node and terminal device. But initiate the modification process of RRC connection, i.e. S209-S210.

S209, terminal device send the identification information of the second network to wireless access network node.

The identification information of second network is used to indicate the signalling that wireless heterogeneous networks connection is used for the second network.At this Apply for that the second network is 4G core net in embodiment, then the identification information of the second network can be the mark of 4G core net.It can Choosing, the identification information of the second network can be carried in (Direct Transfer) message, user's auxiliary information message of direct transferring In (UE Assistance Information message) or connection modification request message.Wherein, connection modification request message It is the message newly extended, is used to indicate the modification that wireless access network node carries out RRC connection.
