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.

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, an embodiment of the present invention provides a communication method, where a core network device supports at least one operator core network, and each operator core network corresponds to one network identifier. When the access network equipment acquires the terminal identification and the network identification corresponding to the terminal identification from the core network equipment, the access network equipment determines the equipment type and the operator identification of the terminal corresponding to the terminal identification according to the terminal identification. And when the access network equipment determines that at least two of the equipment type, the operator identification and the network identification meet the preset conditions, the terminal is accessed to an operator core network corresponding to the network identification through the core network equipment.

As can be seen from the above, in the communication method provided by the present invention, when the access network device is a base station and the device types are a terminal supporting 2B and a terminal supporting 2C, the base station determines the device type of the terminal corresponding to the terminal identifier according to the terminal identifier obtained from the core network device, so that the base station distinguishes 2B and 2C according to the device type of the terminal.

Further, the service provided by the core network of different operators is different. Therefore, after determining the device type of the terminal, the base station further needs to determine whether at least two of the device type, the operator identifier, and the network identifier satisfy the preset condition. Because each operator core network corresponds to one network identifier, when at least two of the equipment type, the operator identifier and the network identifier meet the preset conditions, the terminal is accessed to the operator core network corresponding to the network identifier through the core network equipment, so that the terminal with different equipment types is 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 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 send information carrying a terminal identifier and a network identifier from the core network device. The core network device supports at least one operator core network, and each operator core network corresponds to a network identifier.

The processing unit is further configured to access the terminal to an operator core network corresponding to the network identifier through the core network device when at least two of the device type, the operator identifier, and the network identifier received by the obtaining unit satisfy a 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.

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.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like do not limit the quantity and execution order.

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 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 network identifier includes a private network identifier, each private network core network corresponds to a private network identifier, and each public network core network corresponds to an operator identifier.

Specifically, 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.

When the base station 2 acquires the terminal identifier and the network identifier corresponding to the terminal identifier from the core network device 3, the base station 2 needs to determine the device type and the operator identifier of the terminal 1 corresponding to the terminal identifier according to the terminal identifier.

When the base station 2 determines that the operator identifier is different from the private network identifier and the device type is a terminal of a private network, the base station 2 accesses the terminal 1 to a private network core network corresponding to the private network identifier through the core network device 3.

When the base station 2 determines that the operator identifier is different from the private network identifier and the device type is a terminal of a public network, the base station 2 accesses the terminal 1 to a public network core network corresponding to the operator identifier through the core network device 3.

When the base station 2 determines that the operator identifier is the same as the private network identifier, the base station 2 accesses the terminal 1 to a public network core network corresponding to the operator identifier through the core network device 3.

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 terminal capability detection module, a network identifier detection module, and a core network selection module.

The network identifier detection module is used for acquiring the terminal identifier and the network identifier corresponding to the terminal identifier from the core network device 3; the carrier frequency detection module is used for determining a working frequency point of the terminal 1 corresponding to the terminal identifier according to the terminal identifier acquired by the network identifier detection module; the terminal capability detection module is used for determining the network type of the terminal 1 corresponding to the terminal identification according to the terminal identification acquired by the network identification detection module; the core network selection module is used for determining the operator identifier of the terminal 1 according to the working frequency point determined by the carrier frequency detection module; the core network selection module is also used for determining the network type determined by the terminal capability detection module and determining the equipment type of the terminal 1; the core network selection module is further configured to access the terminal 1 to the operator core network corresponding to the network identifier through the core network device 3 when it is determined that at least two of the device type, the operator identifier, and the network identifier satisfy the preset condition.

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:

when the device types of the operator a and the operator B both include a terminal of a public network and a terminal of a private network, at this time, the access network device 2 needs to include 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) for respectively carrying service data of the terminal of the public network of the operator a and service data of the terminal of the private network, and service data of the terminal of the public network of the operator B and service data of the terminal of the private network.

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 device type of the terminal 1 of the operator a is a terminal of a private network (where service data initiated by the terminal of the private network is referred to as private network service data), 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 initiated by the terminal 1 of 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 a terminal of a public network (where service data initiated by the terminal of the public network is referred to as public network service data), the access network device 2 transmits the 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.

Or,

when the device type of the terminal 1 of the operator a is a terminal of a private network, 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 device type of the terminal 1 of the operator B is a terminal of the private network, 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 device type of the terminal 1 of the operator a is a terminal of a public network, 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 device type of the terminal 1 of the operator B is a terminal of a public network, the access network device 2 transmits 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 service data of the public network networks of the operator A and the operator B and uplink data in the service data of the private network together through a first combiner, and outputting the combined uplink data to an antenna unit.

Or,

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 (evolved Node B, 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 (IoT-NB-B-n-network, an access network device in a future 5G mobile communication network or a Public Land Mobile Network (PLMN) in a future Evolution, which is not limited in this respect.

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 terminal identifier and the network identifier corresponding to the terminal identifier from the core network device 3. The core network device 3 supports at least one operator core network, and each operator core network corresponds to one network identifier.

Specifically, the terminal identifier may be a mobile phone code (IMEI) of the terminal 1.

Specifically, the access network device 2 may obtain the terminal identifier and the network identifier corresponding to the terminal identifier through a system information type 1 (SIB 1) message carrying the terminal identifier and the network identifier and sent by the core network device 3.

And S12, the access network device 2 determines the device type and the operator identification of the terminal 1 corresponding to the terminal identification according to the terminal identification.

Specifically, S12 further includes: s120, the access network device 2 determines the working frequency point of the terminal 1 corresponding to the terminal identifier and the network type supported by the terminal 1 according to the terminal identifier. The network types include public networks and private networks, among others. Specifically, the access network device 2 determines the working frequency point by checking frequency information in a Management Information Base (MIB) signaling reported by the terminal 1. S121, the access network equipment 2 determines the operator identification of the terminal 1 according to the working frequency point. And S122, the access network equipment 2 determines the equipment type of the terminal according to the network type.

Specifically, the network type includes any one of a private network and a public network. S122 further includes S1220, when the access network device 2 determines that the network type is the private network, determining that the device type of the terminal 1 is the terminal of the first network type. And S1221, when the access network device 2 determines that the network type is the public network, determining that the device type of the terminal 1 is the terminal of the second network type.

Specifically, the access network device 2 may query the first configuration table according to the terminal identifier, and determine the device type of the terminal 1 corresponding to the terminal identifier. The first configuration table comprises the corresponding relation among the terminal identification, the network type and the equipment type.

Specifically, the first configuration table is shown in table 1.

TABLE 1

Terminal identification	Network type	Type of device
			T1	Public network	UEu
T2	Private network	UEz
			TN	Public network, private network	UEz、UEu

Wherein TN denotes a terminal N, UEz denotes a terminal supporting a private network (which denotes that the service type initiated by the terminal is private network service), UEu denotes a terminal supporting a public network (which denotes that the service type initiated by the terminal is public network service), and N is an integer greater than 0.

Illustratively, when it is determined according to table 1 that the network type supported by the terminal 1 is a private network, the access network device 2 determines that the device type of the terminal 1 is a terminal of the private network.

When determining that the network type supported by the terminal 1 is the public network according to table 1, the access network device 2 determines that the device type of the terminal 1 is the terminal of the public network.

When determining that the network types supported by the terminal 1 are a public network and a private network according to table 1, the access network device 2 determines that the device types of the terminal 1 are terminals of the public network and the private network.

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

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

TABLE 2

Terminal identification	Frequency point interval	Operator identification
			T1	A1-A2	PLMNA
T2	B1-B2	PLMNB
			T3	C1-C2	PLMNC

Wherein PLMNA denotes operator a, PLMNB denotes operator B, and PLMNC denotes operator C.

For example, assuming that the terminal identifier of the terminal 1 is T1, it can be known that the current working frequency point of the terminal 1 is AN by querying MIB signaling reported by the terminal 1. As can be seen from Table 2, when AN is located in the frequency bin interval of A1-A2, the operator of terminal 1 is identified as PLMNA.

Specifically, when the frequency point information is a frequency point set, the first configuration table is shown in table 3.

TABLE 3

Terminal identification	Frequency point set	Operator identification
			T1	A1、A2、……、AN	PLMNA
T2	B1、B2、……、BN	PLMNB
			T3	C1、C2、……、CN	PLMNC

For example, assuming that the terminal identifier of the terminal 1 is T2, it can be known 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 3, BN is one element in the frequency bin set { B1, B2, … …, BN }, and therefore the operator of terminal 1 is identified as PLMNB.

Specifically, the access network device 2 may determine, according to the terminal identifier of the terminal 1, an operator to which the terminal belongs and an operator core network, thereby facilitating subsequent processes such as charging.

For example, the access network device 2 may determine, according to the terminal identifier of the terminal 1, an operator to which the terminal belongs and an operator core network as shown in table 4.

TABLE 4

Terminal identification	Operator	Operator core network	Access duration	Flow (bit)
					T1	Operator A	Private network core network	50	8800
T2	Operator A	Core network of public network	100	12300

S13, when it is determined that at least two of the device type, the operator identifier, and the network identifier satisfy the preset condition, the access network device 2 accesses the terminal 1 to the operator core network corresponding to the network identifier through the core network device 3.

Specifically, in practical application, the network identifier includes a private network identifier, the operator core network includes at least one of a private network core network and a public network core network, each private network core network corresponds to one private network identifier, each public network core network corresponds to one operator identifier, and S13 includes: s130, when the access network equipment 2 determines that the operator identifier is different from the private network identifier and the equipment type is the terminal of the first network type, the access terminal 1 is accessed to a private network operator core network corresponding to the private network identifier through the core network equipment 3. S131, when the access network device 2 determines that the operator identifier is different from the private network identifier and the device type is a terminal of a second network type, the access network device 3 accesses the terminal 1 to a public network provider core network corresponding to the operator identifier. S132, the access network device 2 determines that the operator identifier is the same as the private network identifier, and the core network device 3 accesses the terminal 1 to the public network provider core network corresponding to the operator identifier.

Specifically, in the communication method provided in the embodiment of the present invention, the core network device 3 divides PLMNs of each operator according to a preset rule, 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 correspondence between the network identifier, the preset operator and the operator core network is shown in table 5.

TABLE 5

When the access network device 2 receives the terminal identifier and the network identifier corresponding to the terminal identifier from the core network device 3, the access network device 2 first determines the operator identifier of the terminal 1 according to the terminal identifier, and if the operator identifier is PLMNA, it indicates that the operator to which the terminal 1 belongs is the operator a. Meanwhile, the access network device 2 further needs to determine the device type of the terminal 1 according to the terminal identifier, and if the device type is UEu, the terminal 1 is determined to be a terminal supporting a public network.

If the private network identifier is PLMNA + PLMN-N, the provider identifier PLMNA is different from the private network identifier PLMNA + PLMN-N, and the device type is UEu, at this time, the terminal needs to be accessed to the public network core network corresponding to the provider identifier PLMNA through the core network device 3.

If the private network identifier is PLMNA, the provider identifier PLMNA is the same as the private network identifier PLMNA, and at this time, the terminal needs to access the public network core network corresponding to the provider identifier PLMNA through the core network device 3.

Or,

when the access network device 2 acquires the terminal identifier and the network identifier corresponding to the terminal identifier from the core network device 3, the access network device 2 first determines, according to the terminal identifier, an operator to which the terminal 1 belongs and a network type of the terminal 1, then the access network device 2 determines, according to the network type, the device type of the terminal 1, and if the device type is UEz, the terminal 1 is determined to be a terminal supporting a proprietary network. Meanwhile, the access network device 2 further needs to determine the operator identifier of the terminal 1 according to the operator, and if the operator identifier is PLMNA, it indicates that the operator to which the terminal 1 belongs is the operator a.

If the private network identifier is PLMNA + PLMN-N, the PLMNA identifier is different from the private network identifier PLMNA + PLMN-N by the known operator identifier, and the device type is UEz, at this time, the terminal needs to be accessed to a private network core network corresponding to the private network identifier PLMNA + PLMN-N through the core network device 3.

Or,

when the device type of the terminal 1 simultaneously satisfies UEu and UEz, if the private network identifier is PLMNA + PLMN-N, the PLMNA identifier is different from the private network identifier PLMNA + PLMN-N by the above-mentioned known operator identifier, and the device type is UEz, so that the terminal needs to access the private network core network corresponding to the private network identifier PLMNA + PLMN-N through the core network device 3.

If the private network identifier is PLMNA, the operator identifier PLMNA is the same as the private network identifier PLMNA, and therefore, the core network device 3 needs to use the public network core network corresponding to the operator identifier PLMNA.

Further, in the embodiment of the present invention, in combination with fig. 3, as shown in fig. 4, the above S12 may include S120, S121, and S122.

Further, in the embodiment of the present invention, in combination with fig. 3, as shown in fig. 4, the above S122 may include S1220 and S1221.

Further, in the embodiment of the present invention, in combination with fig. 3, as shown in fig. 4, the above S13 may include S130, S131, and S132.

As can be seen from the above, in the communication method provided by the present invention, when the access network device is a base station and the device types are a terminal supporting 2B and a terminal supporting 2C, the base station may distinguish the device type of the terminal corresponding to the terminal identifier according to the terminal identifier obtained from the core network device, so that the base station distinguishes 2B and 2C according to the device type of the terminal.

It is well known that the operator core networks that serve different device types differ. Therefore, after determining the device type of the terminal, the base station further needs to determine whether at least two of the device type, the operator identifier, and the network identifier satisfy the preset condition. When at least two of the equipment type, the operator identification and the network identification are determined to meet the preset conditions, the terminal is accessed to the operator core network corresponding to the network identification through the core network equipment, so that the terminal with different equipment types is 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 the 2B and 2C of each operator are accessed to the corresponding core network are solved.

The scheme provided by the embodiment of the invention is mainly introduced from the perspective of a method. To implement the above functions, it includes hardware structures and/or software modules for performing the respective functions. Those of skill in the art will readily appreciate that the present invention can be implemented in hardware or a combination of hardware and computer software, with the exemplary elements and algorithm steps described in connection with the embodiments disclosed herein. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.

The embodiment of the present invention may perform functional module division on the access network device according to the above method example, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. 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.

Fig. 5 is a schematic structural diagram of an access network device 2 according to an embodiment of the present invention. The access network device 2 is configured to determine the device type and the operator identifier of the terminal 1 corresponding to the terminal identifier according to the terminal identifier when the core network device 3 obtains the terminal identifier and the network identifier corresponding to the terminal identifier. And determines the operator core network to which the terminal 1 can access according to the device type, the operator identifier and the network identifier.
