Some concepts related to a private network access method and apparatus provided by the embodiments of the present invention are explained below.
The slicing network referred to in the embodiments of the present invention may be a network slice.
Network slicing: in 5G networks, the concept of network slices is introduced, a network slice being a set of network functions, resources for running the network functions and configurations specific to the network functions, a network slice may constitute an end-to-end logical network. In a 5G network, different types of network slices may be selected for a terminal according to a service requirement of the terminal, for example, the network slices may include different types of network slices applied to a mobile bandwidth (MBB) scenario, an internet of things (IOT) scenario, and a Mobile Edge Computing (MEC) scenario, and each network slice includes a respective service function (e.g., an access and mobility management function (AMF), a User Plane Function (UPF), and a Policy Control Function (PCF), etc.). In the embodiment of the invention, the network equipment can send the private network connection request message of the UE to the private network identification equipment through the slice network, so that the UE establishes communication connection with a service server in a private network for providing service data for the UE.
Based on the problems in the background art, the embodiment of the invention provides a private network access method and a private network access device, which are applied to a scene that UE (user equipment) accesses a private network, wherein network equipment receives a private network connection request message sent by the UE and sends the private network connection request message to slice processing equipment; after receiving a private network connection request message of the UE from a network device, the slice processing device sends a slice query message to the slice management device under the condition that slice integration indication information contained in the private network connection request message indicates that a plurality of slice networks are integrated; the slice management device further determines identification information of at least one slice network according to the identification information of the plurality of slice networks contained in the slice query message, wherein the at least one slice network is an integrated slice network corresponding to the plurality of slice networks, and sends the identification information of the at least one slice network to the slice processing device; the slicing processing device sends the identification information of the at least one slicing network to the network device after receiving the identification information of the at least one slicing network; then the network device sends the private network connection request message to the private network identification device through the at least one slice network; therefore, the private network identification device determines the IP address of the target service server (namely, the service server which provides service data for the UE in the target private network) according to the private network identification information contained in the private network connection request message, and sends the private network connection request message to the target service server. In this way, the UE can establish a communication connection with the target service server (i.e., access the target private network). In the embodiment of the invention, in the process that the UE accesses the target private network through the plurality of slice networks, part of the slice networks in the plurality of slice networks providing private network access service for the UE can be integrated into one slice network, so as to obtain at least one slice network, and the UE accesses the target private network through the at least one slice network after integration, so that the UE can access the private network system through more slice networks and obtain service data from the private network system.
The private network access method and apparatus provided in the embodiment of the present invention may be applied to a wireless communication system, and taking the wireless communication system as a 5G communication system as an example, as shown in fig. 1, the 5G communication system includes a UE101, a network device 102, a slice processing device 103, a slice management device 104, a private network identification device 105, and an external data network 10. Wherein the network device 102 and the slice processing device 103 are devices in an access network; the slice management device 104 and the private network identifying device 105 are devices in a 5G core network; the external data network 10 includes a service server 106 and a service server 107. In general, in practical applications, the connections between the above-mentioned devices or service functions may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience of intuitively representing the connections between the devices.
The network device 102 is used for the UE101 to access a network, and the network device 102 may be a base station, an evolved node base station (eNB), a next generation base station (gNB), a new radio base station (new radio eNB), a macro base station, a micro base station, a high frequency base station or a sending and receiving point (TRP), a non-3GPP access network (e.g., WiFi), and/or a non-3GPP interworking function (N-3 GPP IWF).
The slice processing device 103 is configured to determine whether to send a slice query message to the slice management device 104 after receiving the private network connection request message of the UE101 sent by the network device 102. The slice query message is used to query the identification information of at least one integrated slice network corresponding to a plurality of slice networks providing the private network access service for the UE 101.
The slice management device 104 is configured to determine, according to the identification information of the multiple slice networks providing the private network access service for the UE101, the identification information of at least one integrated slice network corresponding to the multiple slice networks.
The private network identifying device 105 is configured to determine an IP address of a service server (hereinafter referred to as a target service server) that provides service data for the UE101 in a target private network to which the UE101 is to be accessed.
A service server 106 and a service server 107 for providing service data to the UE 101. Alternatively, the service server 106 and the service server 107 may be service servers in different private networks (or private network systems), for example, the service server 106 is a service server in a police private network for providing service data related to police for the UE 101; the service server 107 is a service server in the tax private network, and is used for providing service data related to tax for the UE 101.
In conjunction with the above-described 5G communication system architecture, network device 102 may send a private network connection request message to private network identification device 105 over at least one slice network. Illustratively, as shown in fig. 2, the network device 102 sends a private network connection request message through a slice network 201 and/or a slice network 202. Accordingly, the private network identifying apparatus 105 receives the private network connection request message through the slice network 201 and/or the slice network 202.
It should be understood that the slicing network used when the network device 102 sends the private network connection request message is the same as the slicing network used when the private network identification device 105 receives the private network connection request message. For example, if the network device 102 sends a private network connection request message through the slice network 201, the private network identification device 105 receives the private network connection request message through the slice network 201.

A receiving unit may also be referred to as a receiver, a receiving circuit, or the like, and a transmitting unit may be referred to as a transmitter, a transmitting circuit, or the like.
Portion 31 may comprise one or more boards or chips, each of which may comprise one or more processors and one or more memories, the processors being configured to read and execute programs in the memories to implement baseband processing functions and control of the base station. If a plurality of single boards exist, the single boards can be interconnected to increase the processing capacity. As an alternative implementation, multiple boards may share one or more processors, or multiple boards may share one or more memories. The memory and the processor may be integrated together or may be provided separately. In some embodiments, portions 30 and 31 may be integrated or may be separate.
