Wherein each core network device supports at least one operator core network.
For example, taking the access device 2 as a base station and the core network device 3 supporting at least one operator core network of a preset operator as an example for description, a specific implementation process is as follows:
specifically, the operator core network may be a private network core network (also referred to as a private network) or the operator core network may be a public network core network.
Specifically, the service types include a service of a first network type and a service of a second network type, and the first network type is different from the second network type. Illustratively, the first network type is a private network and the second network type is a public network.
Specifically, the network identifier includes at least one of a private network identifier and a target address, and the target address corresponding to the private network core network is different from the target address corresponding to the public network core network.
When the base station 2 acquires the network identifier from the terminal 1, the base station 2 needs to determine the service type and the home operator of the terminal according to the carrier information of the terminal.
When the base station 2 determines that the service type is a service of a public network (also referred to as a public network service or 2C), and the network identifier only includes a target address, the base station 2 accesses the terminal 1 to a public network core network corresponding to the target address.
When the base station 2 determines that the service type is a service of a private network (also referred to as a private network service or 2B), and the network identifier includes a private network identifier and a target address, the base station 2 accesses the terminal 1 to a private network core network corresponding to the target address.
Fig. 2 shows an architecture of the access network device 2 in the above communication method. As shown in fig. 2, the access network device 2 includes: the device comprises a radio frequency unit and a baseband processing unit. The radio frequency unit is connected to the base station processing unit through a Common Public Radio Interface (CPRI), and the private network core networks of the operator a, the operator B, the operator a, and the operator B are connected to the baseband processing unit of the access network device 2 through NG interfaces.
The baseband processing unit includes a Control Plane (CP) and a User Plane (UP).
The control plane CP includes a carrier frequency detection module, a network identifier detection module, and a core network selection module.
The network identifier detection module is used for acquiring a network identifier from the terminal 1; the carrier frequency detection module is used for determining the service type and the attributive operator of the terminal 1 according to the carrier information of the terminal 1. The core network selection module is used for accessing the terminal 1 to the operator core network corresponding to the network identifier when determining that the service type and the network identifier acquired by the network identifier detection module meet the preset condition; each operator core network corresponds to a network identifier, the operators comprise at least one operator core network, and the operator core network corresponding to the network identifier is the operator core network in the at least one operator core network.
The radio frequency unit comprises an antenna unit, a switch, a first combiner for processing uplink data, a second combiner for processing downlink data and at least two transceivers.
Each transceiver includes a Digital Up Conversion (DUC), a digital to analog converter (DAC), a transmit antenna (TX), a receive antenna (RX), an analog to digital converter (ADC), and a Digital Down Conversion (DDC).
Specifically, in the communication method provided by the present invention, a plurality of communication links are provided for each operator, and each communication link is used for carrying service data of the same service type of the operator.
For example, referring to fig. 2, taking an example that an operator a and an operator b access an access network device 2 through an NG interface at the same time, a specific implementation process is as follows:
when the service types of the service initiated by the terminal 1 of the operator a and the operator B include the public network service and the private network service, the access network device 2 needs to include 4 communication links (e.g., a first communication link composed of a baseband processing unit, a first transceiver, a first combiner, a second combiner, a switch and an antenna unit, a second communication link composed of a baseband processing unit, a second transceiver, a first combiner, a second combiner, a switch and an antenna unit, a third communication link composed of a baseband processing unit, a third transceiver, a first combiner, a second combiner, a switch and an antenna unit, and a fourth communication link composed of a baseband processing unit, a fourth transceiver, a first combiner, a second combiner, a switch and an antenna unit) for respectively carrying the service data (also referred to as private network service data) generated by the operator a 2B and the service data (also referred to as public network service data) generated by the operator B, And private network service data and public network service data of operator B.
Specifically, each of the first communication link, the second communication link, the third communication link, and the fourth communication link includes a carrier link for transmitting uplink data and a carrier link for transmitting downlink data. Such as: the first communication link comprises a carrier link composed of a baseband processing unit, a DUC1, a DAC1, a TX1, a first combiner, a switch and an antenna unit and used for transmitting uplink data, and a carrier link composed of the baseband processing unit, a DDC1, an ADC1, an RX1, a second combiner, a switch and an antenna unit and used for transmitting downlink data.
Suppose that the access network device 2 carries the public network service data of the operator a through the first communication link, carries the private network service data of the operator a through the second communication link, carries the public network service data of the operator b through the third communication link, and carries the private network service data of the operator b through the fourth communication link.
As can be seen from fig. 2, when the terminal 1 of the operator a initiates 2B, the access network device 2 transmits private network service data through the first communication link. Uplink data in the private network service data of the terminal 1 is transmitted through a carrier link for transmitting the uplink data in a first communication link of the access network device 2.
When the terminal 1 of the operator a initiates 2C, the access network device 2 transmits public network service data through the second communication link. Uplink data in the public network service data of the terminal 1 is transmitted through a carrier link for transmitting the uplink data in the second communication link of the access network device 2.
And then, combining uplink data in the service data of the public network service and uplink data in the service data of the private network service together through a first combiner, and outputting the combined uplink data to an antenna unit.
When the terminal 1 of the operator a or the operator b transmits uplink data, the access network device 2 receives downlink data responding to the uplink data. When the antenna unit of the access network device 2 receives the downlink data, the downlink data needs to be distinguished through the second combiner. When it is determined that the downlink data includes downlink data of the private network of the terminal 1 of the operator a, the downlink data needs to be transmitted to the terminal 1 through the carrier link for transmitting the downlink data in the first communication link. When it is determined that the downlink data includes downlink data of the public network of the terminal 1 of the operator a, the downlink data needs to be transmitted to the terminal 1 through the carrier link for transmitting the downlink data in the second communication link.

Specifically, the access network device 2 may query the first configuration table according to the working frequency point of the terminal 1, so as to determine the service type and the affiliated operator of the terminal 1. The first configuration table comprises the corresponding relation among the frequency point information, the service type and the preset operator.
Illustratively, when the frequency point information is the frequency point interval, the first configuration table is shown in table 1.
TABLE 1
| Frequency point interval | Operator presets | Service attributes |
| A1-A2 | Operator A | 2C |
| A3-B4 | Operator A | 2B |
| B1-B2 | Operator B | 2C |
| B3-B4 | Operator B | 2B |
When the working frequency point of the terminal 1 is determined to be AN, it can be known from table 1 that the working frequency point AN is in the frequency point interval a1-a2, and at this time, it can be determined that the service type of the terminal 1 is 2C and the affiliated operator is operator a.
Illustratively, when the frequency point information is a frequency point set, the first configuration table is shown in table 2.
TABLE 2
| Frequency point set | Preset operator | Service attributes |
| A1、A2、……、AN | Operator A | 2C |
| AN+1、AN+2、……、AN+M | Operator A | 2B |
| B1、B2、……、BN | Operator A | 2C |
| BN+1、BN+2、……、BN+M | Operator A | 2B |
Wherein both N and M are greater than 0.

And S13, when the service type and the network identifier are determined to meet the preset conditions, the access network equipment accesses the terminal to the operator core network corresponding to the network identifier. Each operator core network corresponds to a network identifier, and the operator core network corresponding to the network identifier is an operator core network in at least one operator core network.
Specifically, the operator core network includes at least one of a private network core network and a public network core network, the network identifier includes at least one of a private network identifier and a target address, the target address corresponding to the private network core network is different from the target address corresponding to the public network core network, and S13 includes: s130, when the access network device 2 determines that the service type is the service of the first network type and the network identifier includes the private network identifier and the target address, the terminal 1 is accessed to the private network core network corresponding to the target address.

Specifically, the destination address may be an Internet Protocol (IP) address.
Specifically, the terminal 1 may send different network identifiers to the access network device 2 according to a preset rule, so that the access network device 2 may distinguish the service type of the service initiated by the terminal 1 according to the network identifiers.

The second configuration table includes a corresponding relationship between the service type and the network identifier.
Illustratively, the second configuration table is shown in table 3.
TABLE 3
| Type of service | Network identification |
| Private network service | Private network identity + target address |
| Public network service | Target address |
When the terminal 1 determines that the service type of the service initiated is the private network service, it can be known from table 3 that the network identifier that the terminal 1 needs to send to the access network device 2 is "private network identifier (e.g.," Z ") + destination address".
Then, after receiving the network identifier "Z + destination address" sent by the terminal 1, the access network device 2 determines the service type of the terminal 1 and the belonging operator (such as operator a) according to the carrier information of the terminal 1.
In practical application, each operator includes at least one private network core network, and each private network core network provides services for a different terminal 1, so when the access network device 2 determines that the service type is a private network service, and the network identifier includes a private network identifier and a target address, the terminal 1 needs to be accessed to the private network core network corresponding to the target address in the operator a, thereby ensuring user experience.
Alternatively, the first and second electrodes may be,
when the terminal 1 determines that the service type of the service initiated is the public network service, it can be known from table 3 that the network identifier that the terminal 1 needs to send to the access network device 2 is the "target address".
Then, after receiving the network identifier "destination address" sent by the terminal 1, the access network device 2 determines the service type of the terminal 1 and the home operator (such as operator a) according to the carrier information of the terminal 1.
In practical application, each operator includes at least one public network core network, and each public network core network provides services for different terminals 1, so when the access network device 2 determines that the service type is a public network service and the network identifier only includes a target address, the terminal 1 needs to be accessed to the public network core network corresponding to the target address in the operator a.
