Description

Communication method, device and system

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method, device and system.

Background

At present, the concept of a private network is proposed in the communication development, and the private network is understood as a private network relative to a public network, such as an internal network built in a company, a school or a factory. A User Equipment (UE) that is not signed up with a private network does not allow access to the private network. A private network is also called a non-public network (NPN), and generally can identify a type of the private network through a private network identifier (NPN identification, NPN ID), and the UE may reside in the NPN corresponding to the NPN ID supported by the UE and may only initiate a service in the NPN corresponding to the NPN ID subscribed to the UE.

The private network may be a base station configured exclusively for the private network, a cell under a core network, or may be a slice (slice) of a public network, or may be a cell deployed by an operator. And the services of the private network and the public network can be intercommunicated, so that there may be six types of services: a public network service supported by a public network, a private network service directly supported by the public network, a private network service supported by the private network, a public network service directly supported by the private network, a private network service supported by the public network through a non-3GPP interworking function (N3 IWF), and a public network service supported by the private network through N3 IWF. However, in the current network, data is scheduled according to the priority of quality of service (QoS flow), and when data services under the service types are mapped to the same QoS flow priority, the existing scheduling mechanism cannot perform flexible scheduling. For example, when there are data flows belonging to voice services from a public network and data flows belonging to voice services from a private network, the two types of data flows are both data flows of voice services, and the QoS flow priorities are the same, so that data cannot be flexibly scheduled.

Detailed Description

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application, where as shown in fig. 1, the communication system includes a network device and a terminal device, and the network device may include a radio access network device and a core network device. The terminal equipment is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network equipment in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or the function of the core network device and the logical function of the radio access network device may be integrated on the same physical device, or a physical device may be integrated with a part of the function of the core network device and a part of the function of the radio access network device. The terminal equipment may be fixed or mobile. Fig. 1 is a schematic diagram, and other network devices, such as a wireless relay device and a wireless backhaul device, may also be included in the communication system, which are not shown in fig. 1. The embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the communication system. It should be noted that the two radio access network devices shown in fig. 1 may be connected to the same core network device, or may be connected to different core network devices.

In the following, some terms in the present application are explained to facilitate understanding by those skilled in the art:

radio Access Network (RAN) equipment: the device is configured to access the terminal device to the wireless network, and may be an evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), or a relay station or an access point, or a base station in a 5G network, such as a Transmission and Reception Point (TRP) and a controller, which is not limited herein. In a possible manner, the radio access network device may be a base station (e.g., a gNB) with a Centralized Unit (CU) and a Distributed Unit (DU) separated architecture, as shown in fig. 2, where fig. 2 is a schematic protocol stack diagram of the radio access network device according to an embodiment of the present invention. The RAN device may be connected to a core network device (for example, the core network may be a core network of LTE, or a core network of 5G). CU and DU can be understood as the division of the base station from a logical functional point of view. CUs and DUs may be physically separate or deployed together. A plurality of DUs can share one CU. A DU may also connect multiple CUs (not shown). The CU and DU may be connected via an interface, such as an F1 interface. CUs and DUs may be partitioned according to protocol layers of the wireless network. Functions of Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) layers are provided in the CU, and functions of Radio Link Control (RLC), Medium Access Control (MAC) layer, Physical (PHY) layer, and the like are provided in the DU. It is to be understood that the division of CU and DU processing functions according to such protocol layers is merely an example, and may be performed in other manners. For example, a CU or DU may be partitioned to have more protocol layer functionality. For example, a CU or DU may also be divided into partial processing functions with protocol layers. In one design, some of the functions of the RLC layer and the functions of protocol layers above the RLC layer are provided in the CUs, and the remaining functions of the RLC layer and the functions of protocol layers below the RLC layer are provided in the DUs. In another design, the functions of a CU or DU may also be divided according to traffic type or other system requirements. For example, dividing by time delay, setting the function that processing time needs to meet the time delay requirement in DU, and setting the function that does not need to meet the time delay requirement in CU. In another design, a CU may also have one or more functions of the core network. One or more CUs may be centrally located or separately located. For example, the CUs may be located on the network side to facilitate centralized management. The DU may have multiple rf functions, or may have a remote rf function.

The functionality of a CU may be implemented by one entity or by different entities. For example, the functionality of the CU may be further split, e.g. the Control Plane (CP) and the User Plane (UP) are separated, i.e. the control plane (CU-CP) and the CU user plane (CU-UP) of the CU. For example, the CU-CP and CU-UP may be implemented by different functional entities, which may be coupled with the DUs to collectively perform the functions of a base station. In one possible approach, the CU-CP is responsible for the control plane functions, mainly including RRC and PDCP-C. The PDCP-C is mainly responsible for encryption and decryption of control plane data, integrity protection, data transmission and the like. The CU-UP is responsible for user plane functions, including mainly SDAP and PDCP-U. Where the SDAP is primarily responsible for processing data of the core network and mapping data flows (flows) to bearers. The PDCP-U is mainly responsible for encryption and decryption of a data plane, integrity protection, header compression, serial number maintenance, data transmission and the like. Wherein the CU-CP and CU-UP are connected via the E1 interface. The CU-CP represents the connection of the gNB to the core network via the Ng interface. Via F1-C (control plane) and DU connection. CU-UP is connected with DU via F1-U (user plane). Of course, there is also a possible implementation where PDCP-C is also in CU-UP.

Core network equipment: the access mobility management function (AMF) entity may also be referred to as a Session Management Function (SMF) entity, a Mobility Management Entity (MME) or other core network devices.

The terminal equipment: the wireless terminal can be a wireless terminal or a wired terminal, and the wireless terminal can be a device with a wireless transceiving function, can be deployed on land, and comprises indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like, which are not limited herein. It can be understood that, in the embodiment of the present application, the terminal device may also be referred to as a User Equipment (UE).

In the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

It is understood that, in the embodiments of the present application, a terminal device and/or a network device may perform some or all of the steps in the embodiments of the present application, and these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or various modifications of the operations. Further, the various steps may be performed in a different order presented in the embodiments of the application, and not all operations in the embodiments of the application may be performed.

In the embodiments of the present application, there are two concepts of networks, one is a public network and the other is a private network. The private network can generally identify the type of the private network through a private network identifier (NPN ID), different terminal devices support different NPN IDs, and a terminal device can only reside in an NPN corresponding to the NPN ID supported by the terminal device and can only initiate a service in the NPN corresponding to the NPN ID signed by the terminal device. As an implementation, the NPN ID may also be a closed access group identification (CAG ID).

At present, the deployment modes of the private network may be as follows:

1. the private network may be a cell configured with a base station and a core network dedicated to the private network, and a terminal device supporting the private network may reside and initiate a service in the base station and the core network, and is generally called an independent (SA) NPN cell.

2. The private network can also be a slice (slice) of the public network, that is, one slice in the public network can be configured as the private network, all the terminal devices can reside in the network, and after the terminal devices enter a connection state to initiate a service request, the network formulates the service of the terminal device to the corresponding private network slice according to whether the service is the private network service.

3. The private network may also be one cell deployed by the operator. Allowing the residence or initial access of the terminal device under the private network. Such a private network is generally referred to as a Closed Access Group (CAG) cell or a non-standalone (NSA) NPN cell. As a possible implementation manner, as shown in fig. 3, a base station corresponding to a CAG cell may be referred to as a CAG gNB, where the CAG gNB communicates with an Authentication Management Function (AMF) (also referred to as a CAG AMF) of a Public Land Mobile Network (PLMN). In addition, the PLMN AMF is also in communication with a PLMN gNB, which may communicate with the CAG gNB through an Xn/X2 interface. It can be understood that, since the base station and the core network device in the method 3 are both deployed by an operator, the CAG gbb refers to an operator base station supporting a private network, and the CAG AMF refers to an operator core network device supporting a private network. As to whether the CAG gbb and the CAG AMF support the public network service, the embodiment of the present application does not limit this.

It is understood that both of the above modes 2 and 3 are NSA NPN deployments. Since the modes 2 and 3 are deployed by the operator, the method can support the establishment of the X2/Xn connection between the private network base station and the operator base station, and/or the establishment of the connection between the private network core network and the public network core network, or the private network core network and the public network core network are the same core network.

Due to the deployment of private networks, terminal devices can be simply divided into three categories:

1. private network terminal equipment: a terminal device that only signs a contract with a private network; such as smart terminals for smart phones in factories.

2. Terminal equipment for supporting a private network and a public network simultaneously: such as the mobile phone of a private network access person.

3. Public network terminal equipment: only the terminal equipment signed a contract with the public network; such terminal devices are not at all suitable for private networks.

For the three types of terminal devices, the first two types can be applicable to the private network, and the third type is a terminal device which is not applicable to the private network at all.

Under the condition that the service intercommunication mechanism of the private network and the public network is considered in the SA NPN and NSA NPN scenes, the public network can support the private network service, and the private network can also support the public network service.

Taking a scenario that a public network supports a private network service as an example, the following 3 service attributes exist:

1. public network service

2. Private network services belonging to the same operator as the public network, i.e. direct private network services

3. The public network is a UE through a private network service supported by N3IWF (as a possible implementation manner, as shown in fig. 4, the terminal device is a UE, the UE in the public network performs the private network service through N3IWF, that is, the UE is connected with PLMN 3GPP access (access), the PLMN 3GPP access is connected with User Plane Function (UPF) on the PLMN side through N3, the UPF is connected with Data Network (DN) on the PLMN side, and the UPF is connected with SMF on the PLMN side through N4, the SMF is connected with AMF on the PLMN side through N11, the AMF is connected with UE through N1 and connected with PLMN 3GPP access through N2, the DN on the PLMN side is connected with N3IWF on the NPN side, the N3IWF is connected with AMF on the NPN side through N2 and the UPF on the NPN side through N3, the UPF is connected with the NPN side and the SMF on the NPN 75 through N35 4, the SMF and the NPN 11)

Taking a scenario that a private network supports a public network service as an example, the following 3 service attributes exist:

1. private network service

2. Public network services belonging to the same operator as the private network, i.e. direct public network services

3. Private network public network service supported by N3IWF (as a possible implementation, as shown in fig. 5, the terminal device is UE, UE in private network performs private network service through N3IWF, i.e. UE is connected to NPN 3GPP access (access), NPN 3GPP access is connected to UPF of NPN side through N3, the UPF is connected to DN of NPN side, and the UPF is connected to SMF of NPN side through N4, the SMF is connected to AMF of NPN side through N11, the AMF is connected to UE through N1 and connected to PLMN 3GPP access through N2, DN of PLMN side is connected to N3IWF of PLMN side, the N3IWF is connected to AMF of PLMN side through N2 and connected to UPF of PLMN side through N3, the UPF is connected to DN of PLMN side and SMF of PLMN through N4, the SMF is also connected to the AMF through N11)

Therefore, when the service has the above-mentioned multiple service attributes, the scheme of the embodiments of the present application may perform service scheduling better, and a specific implementation scheme is as follows.

Fig. 6 is a flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 6, the method according to the embodiment may include:

optionally, in S601, the second network device obtains a service attribute of the data service of the terminal device.

S602, the second network device sends first information to the first network device.

Accordingly, the first network device receives the first information sent by the second network device. The first information is used for indicating the service attribute of the data service of the terminal equipment.

S603, the first network equipment determines the service attribute of the data service according to the first information.

In this embodiment, the first network device and the second network device are both wireless access network devices; or, the first network device is a radio access network device, and the second network device is a core network device. The radio access network device may be a base station or a CU or a DU or a CU-CP or a CU-UP or other radio access network devices, and the core network device may be an AMF entity or an SMF entity or an MME entity or other core network devices.

For example: when the first network device and the second network device are both radio access network devices, in a CU-DU scenario, the first network device may be a DU, and the second network device is a CU; alternatively, the first network device may be a CU-UP and the second network device may be a CU-CP. Alternatively, the first and second liquid crystal display panels may be,

in a Handover (HO) scenario, a first network device is a target radio access network device of a terminal device, and a second network device is a source radio access network device of the terminal device. Alternatively, the first and second electrodes may be,

in a Dual-Connectivity (DC) scenario, a first network device is a secondary radio access network device of a terminal device, and a second network device is a primary radio access network device of the terminal device.

The second network device may obtain a service attribute of the data service of the terminal device, and then send the first information to the first network device. Wherein the terminal device is currently within the coverage of the first network device. The first information is used for indicating the service attribute of the data service of the terminal equipment. The data service in this embodiment includes at least one of a PDU session, a data radio bearer, and a data service corresponding to a quality of service flow. The data service may be identified by the identification information of the data service. The identification information of the data service may include at least one of a PDU session identification, a data radio bearer identification, and a quality of service flow identification. Accordingly, the data service may be identified by at least one of a PDU session identification, a data radio bearer identification, and a quality of service flow identification. Specifically, the first information is used to indicate a service attribute of the data service identified by the identification information of the data service of the terminal device.

Optionally, the service attribute includes: private network services or public network services. As an implementation manner, the first information may indicate that the service attribute of the data service is a private network service or a public network service. The first network device receives first information sent by the second network device, and the first information indicates a service attribute of the data service of the terminal device, so that the first network device can determine the service attribute of the data service according to the first information. For example, the service attribute of the data service is determined to be a private network service, or the service attribute of the data service is determined to be a public network service. Optionally, after determining the service attribute of the data service, the first network device schedules data corresponding to the data service according to whether the service attribute of the data service is a public network service or a private network service. For example, when the plurality of data services all belong to a voice service, the first network device may preferentially schedule data corresponding to the voice service of the public network service, or preferentially schedule data corresponding to the voice service of the private network service, which is not limited in this embodiment.

Specifically, the first information is used to indicate that the service attribute of the data service identified by the identification information of the data service of the terminal device is a private network service or a public network service. For example, if the data service is a data service corresponding to a PDU session, the data service may be identified by a PDU session identifier. For example, the data service is identified by the PDU session identifier 1, and accordingly, the first network device may determine, according to the first information, that the service attribute of the data service corresponding to the PDU session identifier 1 is a public network service or a private network service, and then the first network device schedules data corresponding to the PDU session identifier 1 according to whether the data service corresponding to the PDU session identifier 1 belongs to the public network service or the private network service. Or, if the data service is a data service corresponding to the DRB, the data service may be identified by the DRB identifier. For example, the data service is identified by the DRB identifier 1, the first network device may determine, according to the first information, that the service attribute of the data service corresponding to the DRB identifier 1 is a public network service or a private network service, and then the first network device schedules the data corresponding to the DRB according to whether the data service corresponding to the DRB identifier 1 belongs to the public network service or the private network service. Or, if the data service is a data service corresponding to the qos flow, the data service may be identified by the qos flow identifier. For example, the data service is identified by the qos flow id 1, the first network device may determine, according to the first information, that the service attribute of the data service corresponding to the qos flow id 1 is a public network service or a private network service, and then the first network device schedules data corresponding to the qos flow according to whether the data service corresponding to the qos flow id 1 belongs to the public network service or the private network service.

In the communication method provided in this embodiment, the second network device obtains the service attribute of the data service of the terminal device, and sends the first information to the first network device, where the first information is used to indicate the service attribute of the data service of the terminal device. Optionally, the service attribute includes: and then the first network equipment determines whether the service attribute of the data service is a private network service or a public network service according to the first information after receiving the first information. After the service attribute of the data service is determined, the first network device can schedule the data corresponding to the data service according to the service attribute, so that the scheduling flexibility of the data service is improved.

In some embodiments, the private network traffic comprises at least one of: private network services transmitted through a private network, and private network services transmitted through a public network. Therefore, when the first information indicates that the service attribute of the data service is the private network service, the first information may indicate that the service attribute of the data service is the private network service transmitted by the private network or the private network service transmitted by the public network. The private network service transmitted through the public network may include: private network services directly supported by the public network and private network services indirectly supported by the public network. The private network service directly supported by the public network may refer to: in the public network, private network service is transmitted to a data network of the private network through the public network; the private network service indirectly supported by the public network may refer to: when the private network service is transmitted through the public network, the private network service is transmitted to the N3IWF of the private network through the user plane of the public network, and is transmitted to the data network of the private network by the N3IWF of the private network. As one implementation manner, as shown in fig. 4, generally, for a private network service indirectly supported by a public network, the public network does not know whether the service is a private network service. Optionally, the first information may include at least one of: private network services transmitted by a private network, private network services directly supported by a public network and private network services indirectly supported by the public network.

The public network service comprises at least one of the following: public network services transmitted through a public network, and public network services transmitted through a private network. Therefore, when the first information indicates that the service attribute of the data service is a public network service, the first information may indicate that the service attribute of the data service is a public network service transmitted by a public network or a public network service transmitted by a private network. The public network service transmitted through the private network may include: public network service directly supported by a private network and public network service indirectly supported by the private network. The public network service directly supported by the private network may refer to: in the private network, public network service is transmitted to the data network of the public network through the private network; the public network service indirectly supported by the private network may refer to: when the public network service is transmitted through the private network, the public network service is transmitted to the N3IWF of the public network through the user plane of the private network, and is transmitted to the data network of the public network through the N3IWF of the public network. As one implementation, as shown in fig. 5, generally, for a public network service indirectly supported by a private network, the private network does not know whether the service is a public network service. Optionally, the first information may include at least one of: public network service transmitted by the public network, public network service directly supported by the private network and public network service indirectly supported by the private network.

As another embodiment, the first information may include: identification information of a public network, or identification information of a private network. For example, if the first information includes identification information of a public network, the first network device may determine, according to the first information, that the service attribute of the data service is a public network service, and may also determine which public network the data service belongs to. If the first information includes identification information of a private network, the first network device may determine, correspondingly, according to the first information, that the service attribute of the data service is a private network service, and may also determine to which private network the data service belongs. The first information includes identification information of a public network, or identification information of a private network, which may be in an explicit manner or an implicit manner. As an implementation manner of an implicit manner, for example, when the first information does not exist, the first information may be defaulted to a public network service; the identification information of the public network service is the same as the identification information of the public network currently accessed by the terminal equipment; optionally, the implementation method is applicable to a scenario in which the network of the current access network of the terminal device is a public network. Or, when the first information does not exist, the first information can be defaulted to private network service; the identification information of the private network service is the same as the identification information of the private network currently accessed by the terminal equipment. Optionally, the implementation manner is applicable to a scenario in which a network of a current access network of the terminal device is a private network.

As yet another implementation, the first information includes a priority of the data traffic, e.g., a priority of the PDU session and/or a priority of the data radio bearer. The second network device may obtain the priority of the data service, and then the second network device sends first information to the first network device, where the first information includes the priority of the data service. Accordingly, the first network device receives the first information and determines the priority of the data service according to the first information. Optionally, the first network device may also schedule data corresponding to the data service according to the priority of the data service, so as to improve flexibility of scheduling the data service. For example, the first network device may schedule data corresponding to the PDU session according to the priority of the PDU session, and/or schedule data corresponding to the DRB according to the priority of the DRB; or, the first network device may schedule data corresponding to the quality of service flow according to the priority of the PDU session and/or the priority of the DRB, and the priority of the quality of service flow.
