Description

Communication method and access network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method and an access network device.

Background

The fifth generation mobile communication technology (5th-generation, 5G) network provides multiple slicing modes, which can satisfy the demands of both customers (2C) and enterprises (2B).

The transceiver devices (e.g. access network devices) in a 5G network are typically multi-antenna devices, such as: 64 Transceiver and Receiver (TR) devices, resulting in very high networking costs. Therefore, operators are seeking a solution for co-establishing a base station by multiple operators and performing network deployment by using the co-established base station. The co-building of the base station means that one base station can meet the requirements of multiple operators, and the equipment of the multiple operators is not centralized in the same base station.

How the base station after being co-constructed distinguishes the 2B and the 2C of each operator, and accesses the 2B and the 2C of each operator to the corresponding core network becomes a problem to be solved urgently.

Disclosure of Invention

The invention provides a communication method and access network equipment, which solve the problem of how to distinguish 2B and 2C of each operator by a base station after co-construction and access the 2B and 2C of each operator to a corresponding core network.

In order to achieve the purpose, the invention adopts the following technical scheme:

in a first aspect, in the communication method provided in the embodiment of the present invention, when the access network device acquires the network identifier from the terminal, the access network device needs to determine the service type of the terminal according to the carrier information of the terminal. Because each operator core network corresponds to a network identifier, 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.

As can be seen from the above, in the communication method provided by the present invention, when the access network device obtains the network identifier from the terminal, the service type of the terminal needs to be determined according to the carrier information of the terminal. Therefore, when the service types include 2B and 2C, the access network device can distinguish the service types of the terminals according to the carrier information of the terminals.

Further, since different operator core networks provide services for terminals with different service types, after determining the service type of the terminal, the access network device needs to determine whether the service type and the network identifier satisfy the preset conditions. 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, so that the terminals of different service types can be accessed to the corresponding operator core network, and the problems that how the base station after co-construction distinguishes 2B and 2C of each operator and accesses the 2B and 2C of each operator to the corresponding core network are solved.

In a second aspect, the present invention provides an access network device, including: an acquisition unit and a processing unit.

Specifically, the obtaining unit is configured to obtain the network identifier from the terminal. Wherein each operator core network corresponds to a network identifier.

The processing unit is configured to determine a service type of the terminal according to the carrier information of the terminal.

The processing unit is further configured to access the terminal to an operator core network corresponding to the network identifier when the service type and the network identifier obtained by the obtaining unit meet the preset condition.

In a third aspect, the present invention provides an access network device, including: communication interface, processor, memory, bus; the memory is used for storing computer execution instructions, and the processor is connected with the memory through a bus. When the access network device is operating, the processor executes the computer-executable instructions stored by the memory to cause the access network device to perform the communication method as provided in the first aspect above.

In a fourth aspect, the invention provides a computer-readable storage medium comprising instructions. The instructions, when executed on a computer, cause the computer to perform the communication method as provided in the first aspect above.

In a fifth aspect, the present invention provides a computer program product which, when run on a computer, causes the computer to perform the communication method as set forth in the first aspect.

It should be noted that all or part of the above computer instructions may be stored on the first computer readable storage medium. The first computer readable storage medium may be packaged with the processor of the access network device or may be packaged separately from the processor of the access network device, which is not limited in the present invention.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a communication method, which is applied to a network system shown in fig. 1, where the network system may include: a terminal 1, an access network device 2 and a core network device 3. 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 service type as a service of a preset network type, where the preset network type includes a public network and a private network, as an example, the 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 first network type and the second network type are different. Illustratively, the first network type may be a private network and the second network type may be a public network.

When the base station 2 acquires the network identifier from the terminal 1, the base station 2 determines the service type of the terminal 1 according to the carrier information of the terminal 1.

When determining 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 meets a preset condition, the base station 2 accesses the terminal 1 to a private network core network corresponding to the network identifier.

Alternatively, the first and second electrodes may be,

when determining 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 meets a preset condition, the base station 2 accesses the terminal 1 to a public network core network corresponding to the network identifier.

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 carrier information of the terminal 1 according to the network identifier acquired by the network identifier detection module; the core network selection module is used for determining the service type of the terminal 1 according to the carrier information determined by the carrier frequency detection module, and 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 conditions.

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 communication link is provided for each operator, each communication link includes two carrier links, which are a carrier link for transmitting uplink data and a carrier link for transmitting downlink data, uplink service data of terminals of different device types of the same operator are transmitted through the carrier links for transmitting uplink data, and downlink service data of terminals of different device types of the same operator are transmitted through the carrier links for transmitting downlink data.

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:

the access network device 2 includes 2 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, and 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) that respectively carry service data (also referred to as private network service data) generated by the operator a 2B and service data (also referred to as public network service data) generated by the operator C, and private network service data and public network service data of the operator B.

Specifically, each of the first communication link and the second 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 a baseband processing unit, a DDC1, an ADC1, an RX1, a second combiner, a switch and an antenna unit and used for transmitting downlink data.

As can be seen from fig. 2, when the service type of the terminal 1 of the operator a is 2B, the access network device 2 transmits the private network service data of the terminal 1 through the first communication link. Wherein, the uplink data in the private network service data of the terminal 1 in the operator a is transmitted through the carrier link for transmitting the uplink data in the first communication link.

When the device type of the terminal 1 of the operator a is 2C, the access network device 2 transmits public network service data through the first communication link. Uplink data in the public network service data of the terminal 1 in the operator a is transmitted through a carrier link used for transmitting the uplink data in the first communication link.

And then, combining uplink data in the public network service data and uplink data in the private network service data together through a first combiner, and outputting the combined uplink data to an antenna unit.

Alternatively, the first and second electrodes may be,

when the service type of the terminal 1 of the operator a is 2B, the access network device 2 transmits private network service data through the first communication link. Wherein, the uplink data in the private network service data of the terminal 1 in the operator a is transmitted through the carrier link for transmitting the uplink data in the first communication link.

When the service type of the terminal 1 of the operator B is 2B, the access network device 2 transmits the private network service data through the second communication link. Wherein, the uplink data in the private network service data of the terminal 1 in the operator B is transmitted through the carrier link for transmitting the uplink data in the second communication link.

When the service type of the terminal 1 of the operator a is 2C, the access network device 2 transmits public network service data through the first communication link. Uplink data in the public network service data of the terminal 1 in the operator a is transmitted through a carrier link used for transmitting the uplink data in the first communication link.

When the service type of the terminal 1 of the operator B is 2C, the access network device 2 transmits the public network service data through the second communication link. Wherein, the uplink data in the public network service data of the terminal 1 in the operator B is transmitted through the carrier link for transmitting the uplink data in the second communication link.

And then, combining uplink data in the public network service data and uplink data in the private network service data of the operator A and the operator B together through a first combiner, and outputting the combined uplink data to an antenna unit.

Alternatively, the first and second electrodes may be,

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 or the public network of the terminal 1 of the operator a, the downlink data needs to be transmitted to the terminal 1 of the operator a 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 or the private network of terminal 1 of operator B, the downlink data needs to be transmitted to terminal 1 of operator B through the carrier link for transmitting the downlink data in the second communication link.

In this embodiment of the present invention, the access network device 2 may be an access network device (BTS) in a global system for mobile communication (GSM), a Code Division Multiple Access (CDMA), an access network device (Node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an access network device (eNB) in a Long Term Evolution (Long Term Evolution, LTE), an access network device (eNB) in an internet of things (IoT) or a narrowband internet of things (NB-IoT), an access network device in a future 5G mobile communication network or a future evolved Public Land Mobile Network (PLMN), which is not limited in this embodiment of the present invention.

The terminal 1 is used to provide voice and/or data connectivity services to a user. The terminal 1 may have different names such as User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a vehicular user equipment, a terminal agent, or a terminal device. Optionally, the terminal 1 may be various handheld devices, vehicle-mounted devices, wearable devices, and computers with communication functions, which is not limited in this embodiment of the present invention. For example, the handheld device may be a smartphone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, and a laptop computer.

The communication method provided by the embodiment of the present invention is described below with reference to the network system shown in fig. 1.

As shown in fig. 3, the communication method provided by the embodiment of the present invention includes the following steps S11-S13:

s11, the access network device 2 obtains the network identifier from the terminal 1. Wherein each operator core network corresponds to a network identifier.

Specifically, the access network device 2 may obtain the network identifier through a Protocol Data Unit (PDU) session initiated by the terminal 1.

Specifically, the network identifier is determined by the terminal 1 according to the service type of the originating service.

Specifically, when the terminal 1 initiates a private network service or a public network service, the private network service or the public network service may be initiated through a mobile phone software (APP) installed on the terminal 1.

Specifically, the operator includes at least one core network device 3, and each core network device 3 supports at least one operator core network.

S12, the access network device 2 determines the service type of the terminal 1 according to the carrier information of the terminal 1.

Specifically, when the carrier information is a working frequency point, the access network device 2 needs to determine the service type of the terminal 1 according to the working frequency point of the terminal 1.

Specifically, the access network device 2 determines the working frequency point by checking carrier information in a Management Information Base (MIB) signaling reported by the terminal 1.

Specifically, the access network device 2 may query the first configuration table according to the working frequency point, and determine the service type of the terminal 1. The first configuration table comprises a corresponding relation between the frequency point information and the service type.

Specifically, when the frequency point information is the frequency point interval, the first configuration table is shown in table 1.

TABLE 1

Illustratively, when the access network device 2 acquires the network identifier from the terminal 1, the access network device 2 may know that the current working frequency point of the terminal 1 is AN through querying AN MIB signaling reported by the terminal 1. As can be seen from Table 1, when AN is located in the frequency bin interval of A1-A2, the service type of terminal 1 is determined to be 2B.

Specifically, when the frequency point information is a frequency point set, the first configuration table is shown in table 2.

TABLE 2

Frequency point set	Type of service
		A1、A2、……、AN	2B
B1、B2、……、BN	2C

Illustratively, when the access network device 2 acquires the network identifier from the terminal 1, the access network device 2 may know that the current working frequency point of the terminal 1 is BN by querying the MIB signaling reported by the terminal 1. As can be seen from table 2, BN is one element in the frequency point set { B1, B2, … …, BN }, and therefore the traffic type of terminal 1 is 2C.

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.

Specifically, the network identifier includes at least one of a private network identifier and a core network identifier, the operator core network includes at least one of a private network core network and a public network core network, and a target address corresponding to the private network core network is different from a target address corresponding to the public network core network. And when the access network equipment 2 determines that the service type is the service of the private network and the network identifier comprises the private network identifier and the core network identifier, accessing the terminal 1 to the private network core network corresponding to the core network identifier.

And when the access network equipment 2 determines that the service type is the service of the public network and the network identifier only contains the core network identifier, accessing the terminal 1 to the public network core network corresponding to the core network identifier.

Specifically, the terminal 1 queries the second configuration table according to the service type of the originating service, and determines the network identifier. 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

When the terminal 1 determines that the initiated service type is 2B, 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 ") + core network identifier (e.g., PLMNA-N, where PLMNA-N represents the nth operator core network of operator a)".

Then, after receiving the network identifier "Z + PLMNA-N" sent by the terminal 1, the access network device 2 determines the service type of the terminal 1 according to the carrier information of the terminal 1.

When the access network device 2 determines that the network identifier includes a private network identifier and a core network identifier, it may know that the service type initiated by the terminal 1 is 2B. Therefore, the terminal 1 needs to be accessed to the private network core network of the operator a. In practical application, each operator includes at least one private network core network, and each private network core network provides services for different terminals 1, so that it is necessary to determine, according to the core network identifier, a private network core network corresponding to the core network identifier PLMNA-N to which the terminal 1 should access the operator a, so that each terminal 1 can access the corresponding operator core network, and user experience is guaranteed.

Alternatively, the first and second electrodes may be,

when the terminal 1 determines that the initiated service type is 2C, 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 "PLMNA-N".

Then, after receiving the network identifier "PLMNA-N" sent by the terminal 1, the access network device 2 determines the service type of the terminal 1 according to the carrier information of the terminal 1.

When the access network device 2 determines that the network identifier only includes the core network identifier, it may know that the service type initiated by the terminal 1 is 2C. Therefore, the terminal 1 needs to be accessed to the public network core network of the operator a. 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 that it is necessary to determine, according to the core network identifier, that the terminal 1 should access the public network core network corresponding to the core network identifier PLMNA-N of the operator a, so that each terminal 1 can be accessed to the corresponding operator core network, and user experience is guaranteed.

In particular, the PLMN is a network established and operated for the purpose of providing land mobile services to the public, due to the operator to which it is approved. Thus, the PLMNs of each operator are different (e.g., PLMNA is the PLMN of operator a). Therefore, in the communication method provided in the embodiment of the present invention, the terminal 1 divides PLMNs of each operator, and determines different network identifiers, thereby implementing a distinction between a public network core network and a private network core network of each operator.

For example, the terminal 1 may divide the PLMNA-N according to the rules shown in table 4, so as to distinguish the public network core network and the private network core network of the operator a. Table 4 includes the correspondence between the preset operator, the operator network, and the network identifier.

TABLE 4

When the access network device 2 receives the network identifier from the terminal 1, the access network device 2 first determines the service type of the terminal 1 according to the carrier information of the terminal 1.

And if the service type is 2C and the network identifier is 'PLMNA-M', accessing the terminal 1 to a public network core network corresponding to the core network identifier PLMNA-M in the operator A.

Alternatively, the first and second electrodes may be,

and if the service type is 2B and the network identifier is Z + PLMNA-N, accessing the terminal 1 to a special network core network corresponding to the core network identifier PLMNA-N in the operator A.

In the embodiment of the present invention, in combination with fig. 3, as shown in fig. 4, S12 described above may include S120.

Further, in the embodiment of the present invention, in combination with fig. 3, as shown in fig. 4, the above S13 may include S130 and S131.

When the access network equipment acquires the network identifier from the terminal in the communication method provided by the invention, the service type of the terminal needs to be determined according to the carrier information of the terminal. Therefore, when the service types include 2B and 2C, the access network device can distinguish the service types of the terminals according to the carrier information of the terminals.

Since different operator core networks provide services for terminals with different service types, after determining the service type of the terminal, the access network device needs to determine whether the service type and the network identifier satisfy preset conditions. 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, so that the terminals of different service types can be accessed to the corresponding operator core network, and the problems that how the base station after co-construction distinguishes 2B and 2C of each operator and accesses the 2B and 2C of each operator to the corresponding core network are solved.

The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, the division of the modules in the embodiment of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
