As mentioned in the related art, when a user equipment is connected to a home gateway in a non-3GPP manner at home to access a 4G/5G network, qoS (Quality of Service ) control can only be achieved between the network side and the home gateway side (and the home gateway needs to sign up for QoS service) due to the difference of network attributes and device access identities, but consistent QoS control cannot be achieved between the home gateway and the user terminal equipment side, resulting in failure to satisfy end-to-end QoS and failure to guarantee service requirements of high bandwidth applications.
Therefore, the application firstly provides a method for controlling the service quality in the heterogeneous network, which can overcome the defects, can realize end-to-end service quality control in the heterogeneous network, can ensure consistency of service experience and ensure service requirements of terminals for high-bandwidth application.
The implementation terminal of the embodiment of the application may be various devices capable of serving as a home gateway, such as a router, a switch, a personal computer, a firewall, and the like.
Fig. 1 is a system architecture diagram illustrating a method of controlling quality of service in a heterogeneous network according to an exemplary embodiment. As shown in fig. 1, the system architecture 100 includes a terminal device 101 and a second network 102, where the terminal device 101 belongs to a first network, and the second network 102 includes a home gateway 103, a base station 104, and a plurality of network elements, and the home gateway 103 also belongs to the first network, that is, the home gateway 103 belongs to both the first network and the second network, and is a data forwarding node when the terminal device 101 in the first network communicates with the base station 104 in the second network 102. The terminal device 101 has first identification information on the second network 102 and the home gateway 103 has second identification information on the second network 102. Thus, the system architecture 100 is a heterogeneous network. The home gateway 103 is an implementation terminal of the embodiment of the present application. When a method for controlling quality of service in a heterogeneous network provided in the present application is applied to the system architecture shown in fig. 1, a specific procedure may be as follows: first, the terminal device 101 sends first quality of service requirement information and first identification information of the terminal device 101 to the accessed home gateway 103; then, after obtaining the first quality of service requirement information and the first identification information, the home gateway 103 further adds own second identification information to the first quality of service requirement information, thereby forming second quality of service requirement information; then, the home gateway 103 sends the second qos requirement information and the first identification information to the network element in the second network 102, so that the qos flow and the corresponding qos rule and qos flow configuration information can be determined in the second network 102 according to the second qos requirement information; finally, the home gateway 103, the terminal device 101, the base station 104, and the like in the system architecture 100 can perform quality of service control according to various information such as the quality of service rule related to the quality of service flow and the quality of service flow configuration information, so as to implement end-to-end quality of service control between the terminal device 101 and the base station 104.
In one embodiment of the present application, the first network is a WIFI network.
In one embodiment of the present application, the second network is a 4G or 5G network.
It should be noted that fig. 1 is only one embodiment of the present application, and although in the embodiment of fig. 1, the terminal device is a smart phone, and only one terminal device accesses the home gateway, in other embodiments of the present application, the terminal device may also be various types of terminal devices such as a laptop, a wearable device, and so on, and at the same time, there may be one or more terminal devices that access the home gateway. The embodiments of the present application should not be limited in any way, nor should the scope of protection of the present application be limited in any way.
Fig. 2 is a flowchart illustrating a method of controlling quality of service in a heterogeneous network, which may be performed by a home gateway such as a router, according to an exemplary embodiment. As shown in fig. 2, the following steps may be included:
step 210, after the user terminal accesses the home gateway through a first network in the heterogeneous network, acquiring, through the first network, first quality of service requirement information and first identification information sent by the user terminal, where the home gateway accesses a second network in the heterogeneous network, the second network includes a base station, the user terminal is communicatively connected with the base station through the second network, and the first identification information is identification information of the user terminal in the second network.
In one embodiment of the present application, the first network is a WIFI network.
Specifically, the second network may be a network conforming to the 3GPP (3 rd Generation Partnership Project, third generation partnership project) specifications such as 4G or 5G, and the first network may be a network of a non-3GPP mode such as WIFI or bluetooth, so that the first network and the second network are heterogeneous networks. The home gateway may be in communication with devices in the first network or in communication with devices in the second network.
The identification information of the user terminal in the second network may be, for example, a mobile phone number or the like.
The first quality of service requirement information may include QoS. QoS (Quality of Service ) refers to a network that can utilize various basic technologies to provide better service capability for specified network communications, and is a security mechanism of the network, and is a technology for solving the problems of network delay and congestion. The QoS may include information such as packet loss rate.
The second network may include other network elements in the 4G network or the 5G network in addition to the base station.
Fig. 3 is a flow diagram illustrating an implementation of controlling quality of service in a heterogeneous network according to an example embodiment. Referring to fig. 3, first, a UE (User Equipment) accesses a 5G RG (Residential Gateway, home gateway) through non-3GPP such as WIFI. The UE then sends a QoS-containing traffic requirement to the 5G RG, which also carries the UE identity.
Step 220, sending second qos requirement information and first identification information to the second network, so as to determine qos rules and qos flow configuration information based on the requirements of the user terminal in the second network according to the second qos requirement information and the first identification information of the user terminal in the second network, and controlling data transmission between the user terminal and the base station in the heterogeneous network according to the conversion of qos rules and qos flow configuration information between the heterogeneous networks, wherein the second qos requirement information includes the first qos requirement information and the second identification information of the home gateway in the second network.
The second quality of service requirement information may include QoS and second identification information.
The quality of service rule is a QoS rule and the quality of service flow configuration information is QoS flow configuration information. The QoS rules, qoS flow configuration information correspond to QoS flows (quality of service flows), which may be determined in network elements in the second network. After the QoS flow is determined, various information related to the QoS flow is provided to various devices such as a home gateway, a base station, a user terminal, and the like, thereby implementing end-to-end QoS control.
Fig. 4 is a flow chart illustrating a determination of quality of service flows in a second network based on second quality of service requirement information according to an example embodiment. In the fig. 4 embodiment, the second network further comprises application function (AF, application Function) network elements, policy control function (PCF, policy Control function) network elements, session management function (SMF, session Management Function) network elements and unified data management function (UDM, unified Data Management) network elements, which may be network elements in a 5G core network. As shown in fig. 4, the following steps may be included:
step 410, receiving, by the application function network element, the second quality of service requirement information, and sending, by the application function network element, a quality of service request to the policy control function network element, the quality of service request including the second quality of service requirement information and the first identification information.
With continued reference to fig. 3, the 5g RG sends a service requirement containing QoS to the AF, and the service requirement carries a UE identifier and an RG identifier; the AF then forwards the QOS request to the PCF, thus enabling the PCF to obtain the UE identity and RG identity. It is easy to understand that the second network may further comprise a NEF (Network Exposure Function, network open function) network element, and that the 5G RG may also send QoS-containing traffic demands to the NEF, as shown in fig. 3.
And 420, formulating a policy and charging control rule in the policy control function network element according to the second service quality requirement information in the received service quality request, and transmitting the policy and charging control rule to the session management function network element, wherein the policy and charging control rule comprises the first identification information and the second identification information.
Specifically, with continued reference to fig. 3, the pcf may formulate PCC rules (Policy and Charging Control Rule, policy and charging control rules) based on the received quality of service requirement information, pre-configuration information, and other collected information, and send the PCC rules to the SMF. Besides the UE identification and the RG identification, the PCC rule also comprises rule identification, execution priority, control strategy, qoS identification, uplink and downlink maximum code rate/guaranteed code rate, data flow allocation and priority information, which are mainly used for detecting and strategy control of service data flow and carrying out correct charging on the service data flow.
The PCF may include information collected from network elements such as AF, SMF, AMF (Access and Mobility Management Function, access and mobility management network elements) that may provide the PCF with network identification of the terminal, SUPI (identity) of the terminal, user location information, terminal IP address, type of media transmitted, source and destination ports, statistical analysis and prediction information of traffic, etc. This information, along with the pre-configuration information on the PCF, may be involved in the formulation of PCC rules. Nor does the formulation of PCC rules necessarily require all of this information.
Step 430, performing subscription information query in the unified data management function network element according to the first identification information and the second identification information by the session management function network element to obtain the first subscription information of the user terminal and the second subscription information of the home gateway respectively.
The SMF stores subscription information of each device in advance.
With continued reference to fig. 3, after the SMF obtains the PCC rule, the UDM requests to query the UDM for subscription information of the UE and the 5G RG, and the UDM returns the subscription information of the UE and the 5G RG to the SMF.
In step 440, a quality of service flow based on the quality of service requirement of the user terminal is determined in the session management function network element according to the policy and charging control rule, the first subscription information and the second subscription information.
The QoS flow is a QoS flow, one QoS flow can be used for transmitting a plurality of service data flows, is a set of service data flows with the same QoS requirement, and finally the determined QoS flow is matched with the QoS requirement of the user terminal; after determining the QoS flows, qoS flow configurations, qoS rules, packet detection rules, qoS enforcement rules, and the like, corresponding to each QoS flow may be further determined.
With continued reference to fig. 3, after obtaining subscription information of the UE and the 5G RG, the smf determines an RG QoS flow based on the UE requirements according to PCC rules, subscription information, and other configuration information, so as to obtain an appropriate QoS flow. On this basis, the SMF may also determine QoS flow configurations, qoS rules, packet detection rules, qoS enforcement rules, etc. corresponding to the QoS flows.
In one embodiment of the present application, controlling data transmission between a user terminal and a base station according to conversion of quality of service rules and quality of service flow configuration information between heterogeneous networks includes: receiving a downlink data packet sent by a base station through a radio bearer, wherein the radio bearer is used for carrying out service quality control on the downlink data packet sent by the base station, the radio bearer is obtained by mapping a service quality stream corresponding to service quality stream configuration information according to parameter information in the service quality stream configuration information, and the service quality stream configuration information is obtained by the base station from a session management function network element; and sending the downlink data packet to the user terminal.
With continued reference to fig. 3, after determining the RG QoS flow based on the UE requirement, the smf sends the RG QoS flow configuration based on the UE requirement to a base station (RAN), and the base station performs radio resource configuration according to the QoS flow configuration to form a mapping relationship between the RG QoS flow and a radio bearer, and then sends the mapping relationship between the RG QoS flow and the radio bearer to a 5G RG, and the base station may send a downlink data packet through the radio bearer. Thus, qoS control for the downlink data packet is realized.
Each QoS flow, whether guaranteed or not, corresponds to a QoS flow configuration, where the QoS flow configuration includes information such as QoS identification, allocation and retention priority, and code rate, and the SMF sends the QoS flow configuration to the base station for resource scheduling by the base station.
In one embodiment of the present application, the second network further includes a user plane function network element, and the packet detection rule and the qos execution rule corresponding to the qos flow are further determined in the session management function network element, and the heterogeneous network further performs qos control according to the packet detection rule and the qos execution rule by: transmitting packet detection rules and service quality execution rules to the user plane function network element through the session management function network element; and mapping the downlink data packet of the base station to a corresponding service quality stream according to the packet detection rule and the service quality execution rule by the user plane function network element.
With continued reference to fig. 3, after determining the RG QoS flow based on the UE requirement, the smf further sends a packet detection rule and an RG QoS execution rule to a UPF (Userplane Function ) network element, and after obtaining the packet detection rule and the RG QoS execution rule, the UPF can correctly detect a downlink service data flow, and map the downlink service data flow to a correct QoS flow for transmission.
With continued reference to fig. 3, after determining the RG QoS flow based on the UE requirement, the smf further sends the QoS rule and the code rate requirement contained in the RG to the 5G RG, and after obtaining the QoS rule, the 5G RG binds the UE to the corresponding QoS rule, so that QoS control can be performed on the downlink data packet sent to the UE.
In one embodiment of the present application, controlling data transmission between a user terminal and a base station according to the conversion of the qos rule and the qos flow configuration information between heterogeneous networks, further includes: receiving a quality of service rule from a session management function network element; converting the service quality rule to obtain a converted service quality rule, and transmitting the converted service quality rule to the user terminal so that the user terminal can control the service quality of the uplink data packet transmitted to the home gateway according to the converted service quality rule; and detecting the uplink data packet from the user terminal according to the service quality rule, and mapping the uplink data packet to a corresponding service quality stream so as to transmit the uplink data packet through the service quality stream.
With continued reference to fig. 3, after obtaining the QoS rule, the 5G RG further performs QoS rule conversion to obtain a converted QoS rule, and sends the converted QoS rule to the UE, and the UE can identify the converted QoS rule, so that QoS control is performed on the uplink data packet according to the converted QoS rule, and sends the uplink data packet to the 5G RG. The 5G RG uses QoS rule to detect the uplink data packet, maps the uplink data packet to the correct QoS flow, and further maps the QoS flow to the corresponding radio bearer for transmission according to the obtained mapping relation between RG QoS flow and radio bearer. In this way, end-to-end QoS control is achieved during traffic data transmission between the user equipment and the base station.
In summary, the embodiment of the application proposes a scheme for controlling the service quality in a heterogeneous network, which aims at the problems that when a user terminal device accesses a 3GPP network in a non-3GPP mode through a connecting home gateway, the whole-process end-to-end QoS control cannot be realized, so that the use of high bandwidth application cannot be guaranteed, and the like. The whole scheme does not need 5G home gateway to sign up QoS business or to carry out local QoS policy customization, but the network side carries out whole-course end-to-end QoS control between heterogeneous networks based on UE business requirement and UE business sign information, and the network side grasps QoS policy and control right of the user terminal, thereby realizing flexible access of users and simultaneously guaranteeing business requirement of high bandwidth application. In addition, when the user terminal is switched from the base station to the 5G network, the QoS can be ensured based on the original QoS service requirement, and QoS seamless switching is realized.
According to a second aspect of the present application, there is also provided an apparatus for controlling quality of service in a heterogeneous network, which may be located in a home gateway. The following is a system embodiment of the present application.
