[0034] Embodiments of the present disclosure may be applied to various communication systems. Considering the rapid development of communications, there are certainly future types of communication technologies and systems with which the present disclosure may be implemented. It should not be construed as limiting the scope of the present invention to only the above-mentioned systems. For purposes of illustration, embodiments of the present disclosure will be described with reference to a 5G communication system.

[0035] The term "network equipment" as used herein includes, but is not limited to, a base station (BS), a gateway, a registration management entity, and other appropriate equipment in a communication system. The term "base station" or "BS" refers to a Node B (Node B or NB), an evolved Node B (eNodeB or eNB), a NR NB (also known as a gNB), a remote radio unit (RRU), a radio head (RH), a remote radio head (RRH), a relay, a low power node such as a femto, a pico, etc.

[0044] As described above, 5G communication and wired communication use different residential gateways that should be coordinated. In the 5G communication network, a 5G-RG that has been modified for accessing the 5G core network is used. The 5G-RG can act as a third generation partnership project (3GPP) user equipment (UE), which is assumed to terminate 3GPP non-access stratum (NAS) signaling and support UE routing policy (URSP). In the fixed network (FN), an unmodified FN-RG is used to access the 5G core network. The wired access entity (e.g., an access gateway function (AGF) device) can terminate 3GPP NAS signaling on behalf of the FN-RG.

[0045] Figure 1 FIG. 1 is a schematic diagram of a communication system 100 for 5G-RG using a wired 5G access network to access a 5G core network. Figure 1 As shown, the communication system 100 may include 5G-RG 110, W-AGF 120, and a policy control function (PCF) 130. The communication system 100 may also include one or more of the following: a service controller (e.g., an automatic configuration server (ACS) 140), an access and mobility management function (AMF) 150, a session management function (SMF) 160, a unified data repository (UDR) 170, a network exposure (exposure) function (NEF) 190, a user data management (UDM) 175, and a user plane function (UPF) 180. It should be noted that Figure 1 The devices shown are only examples. 5G-RG 110, W-AGF 120 and ACS 140 may involve wired access. For clarity, the interfaces between the devices are omitted.

[0046] like Figure 1As shown, 5G-RG110 can behave as a conventional 3GPP UE. That is, 5G-RG110 can exchange NAS / N1 signaling with the 5G core network. NAS / N1 signaling may include: NAS registration management and connection management (RM / CM), registering to the 5G core network and establishing a signaling connection with the 5G core network; NAS session management (SM) (called PDU session) for establishing / modifying / releasing data connection capabilities via the 5G core network. 5G-RG110 can receive URSP policy from PCF 130 via AMF 150.

[0047] Figure 2 FIG. 2 is a schematic diagram of a communication system 200 for FN-RG. Figure 2 As shown, the communication system 200 may include FN-RG 210, W-AGF 220, and a policy control function (PCF) 230. The communication system 200 may also include an automatic configuration server (ACS) 240, an access and mobility management function (AMF) 250, a session management function (SMF) 260, a unified data repository (UDR) 270, a network exposure function (NEF) 290, a user data management (UDM) 275, and a user plane function (UPF) 280. It should be noted that Figure 2 The modules, entities and devices shown are examples only. FN-RG210, W-AGF220 and ACS240 may involve wired access. For clarity, the interfaces between devices are omitted.

[0048] like Figure 2 As shown, the 3GPPN1 / NAS of FN-RG210 is terminated on W-AGF220. W-AGF220 can exchange NAS / N1 signaling with the 5G core network on behalf of the FN-RG210 served by W-AGF220. NAS / N1 signaling may include: NAS RM / CM registers and establishes a signaling connection with the 5G core network; NAS SM establishes / modifies / releases data connection capabilities (called PDU sessions) through the 5G core network. W-AGF220 can receive URSP policies from PCF240 via AMF 250.

[0049] From the perspective of the 5G core network, both 5G-RG110 and FN-RG210 are terminal devices. Therefore, in the case of FN-RG210, PCF140 / 240 can determine the corresponding URSP policy and send it to 5G-RG110 or W-AGF220. PCF140 / 240 can obtain policy-related subscription information about the terminal device (or RG) from UDR170 / 270.

[0050] In addition, in the wired network, ACS140 / 240 can be configured by the wired operator to deploy RGs in the user premises. Both 5G-RG110 and FN-RG210 can receive policies from the wired ACS140 / 240. 5G-RG110 and FN-RG210 can use the user plane to exchange information with ACS140 / 240.

[0051] However, potential policy-related coordination between ACS and PCF policies has not been discussed. Potential policies may correspond to mappings from applications (e.g., Internet / IMS Voice / IPTV) to data sessions. Data sessions may involve parameters such as Data Network Name (DNN) in 5GC, Slice Identifier S-NSSAI, which in turn refer to service multiplexers (e.g., Virtual LANs) used on wired access.

[0052] Potential policies may also correspond to QoS related policy mappings. More dynamic information related to the mapping of uplink (link from terminal device to core network) IP flows (or Ethernet flows) to the QoS that the UL data flows need to receive.

[0053] More specifically, regarding the mapping from applications to data sessions, in 5GC, PCF130 can provide URSP rules containing mappings from traffic filters to PDU session parameters to the terminal device. Traffic filters can correspond to application identifiers (e.g., operating system IDs) or IP descriptor traffic related filters (e.g., destination IP "triplets") and other traffic descriptors. The wired-defined policy sent by ACS140 can associate applications (e.g., Internet / IMS voice / IPTV) with L2 headers that act as service multiplexers (e.g., VLANs) on wired access. Therefore, it is necessary to define how the two rules are mapped in the case of 5G-RG and FN-RG networks.

[0054] In addition, regarding QoS-related policy mapping, in 3GPP, when a PDU session is established, SMF160 / 260 can obtain QoS policies from PCF130 / 230. These policies map traffic identified by some filters (for example, in the case of an IP type PDU session, the filter can be an application ID or a five-tuple, or in the case of an Ethernet type PDU session, the filter can be filtering on the Ethernet header) to a 3GPP QoS parameter set, the main parameter of which is 5QI. Traffic within a PDU session to receive the same QoS treatment can be grouped within a QoS flow. 5G core network signaling can provide mapping between QoS flows and 3GPP QoS parameters including 5QI to the 5G access network and terminal equipment (for example, 5G-RG110 or W-AGF220 representing FN-RG210). Therefore, it is necessary to define how the 5G core network signaling related to 5G CQoS is mapped to wired QoS policies.

[0055] According to an embodiment of the present disclosure, the service controller is able to coordinate between information about wireless subscriptions for mapping from a traffic multiplexer used in wired access to a wireless data session selector and information about mapping application traffic to a traffic multiplexer used in wired access sent to a wired residential gateway device. In this way, communication between a network device and a configuration server is achieved, thereby coordinating wired and wireless policy controllers.

[0056] Figure 3 Schematic diagram of a communication system 300 in which embodiments of the present disclosure may be implemented is shown. Figure 3 As shown, the communication system 300 may include 5G-RG 310, FN-RG 315, W-AGF 320, and a policy control function (PCF) 330. The communication system 300 may also include one or more of the following: an automatic configuration server (ACS) 340, an access and mobility management function (AMF) 350, a session management function (SMF) 360, a unified data repository (UDR) 370, a user data management (UDM) 375, a user plane function (UPF) 380, and a network exposure function (NEF) 390.

[0057] It should be noted that 5G-RG 310, FN-RG 315, W-AGF 320, PCF 330, automatic configuration server (ACS) 340, AMF 350, SMF 360, UDR 370, UDM 375, UPF 380 and NEF 390 can be implemented at any device, entity or module. It should be noted that Figure 3 The devices, modules or entities shown are merely examples. It should be understood that the communication system 300 may also include other elements that are omitted for clarity. Figure 3 The number of devices, modules or entities shown in the figures is given for illustrative purposes and does not imply any limitation.

[0058] The communication in the communication system 300 may be implemented according to any appropriate communication protocol, including but not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G) and fifth generation (5G), wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol currently known or developed in the future. In addition, the communication may utilize any appropriate wireless communication technology, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDMA) and / or any other technology currently known or to be developed in the future.

[0059] Figure 4 A schematic diagram of an interaction 400 according to an embodiment of the present disclosure is shown. The interaction 400 may be implemented on any suitable device. For illustrative purposes only, the interaction 400 is described as being implemented between the FN-RG 315, the W-AGF 320, the PCF 330, and the ACF 340.

[0060] For 5G-RG, the URSP sent by PCF 340 to 5G-RG 310 can control the 5G-RG mapping from applications to PDU session parameters (DNN, S-NSSAI). The wired configuration also defines the mapping from applications to L2 headers (VLANs) used as service multiplexers on wired access.

[0061] For FN-RG, ACS 340 can control how FN-RG 315 sends UL traffic on the VLAN corresponding to the target application. ACS 340 generates 4002 second information. The second information can be used to map the application to the traffic multiplexer used on the wired access of FN-RG 315. ACS 340 sends 4004 the second information to FN-RG 315.

[0062] ACS 340 generates 4005 first information based on the second information to ensure mapping between the first information and the second information. In this way, mapping between the first information and the second information is achieved. The first information is about wireless subscription, which is for mapping from the traffic multiplexer used in wired access to the wireless data session selector. The traffic multiplexer used in wired access exists and should not be changed due to the introduction of 5GC. In some embodiments, ACS 340 may send 4010 information to PCF 330. In some embodiments, the first information may not be sent directly from ACS 340 to PCF 330. In some embodiments, the OSS (operation) system coordinates the wired parameter configuration of the wired access in ACS 340 with the wireless subscription-related policy data used by PCF 330 through the existing API on ACS 340. The OSS system should ensure that the coordination is completed and can communicate with PCF via 3GPP NEF 390, UDM375 and UDR370. Wireless subscription is associated with wired access.

[0063] In some embodiments, ACS 340 may send the first information to UDM 375 (possibly via NEF 390). UDM 375 may store the first information in UDR 370. PCF 330 may access UDR 370 to obtain the first information. In this way, indirect interaction between ACS 340 and PCF 330 is completed. In this way, new application program interfaces (APIs) in UDM 375, NEF 390 allow ACS 340 or OSS to control the mapping from the multiplexing identifier used on the wired access to the data session processed by the 5G core network.

[0064] For example, in some embodiments, the Operation Support System (OSS) can use the list of subscribed PDU sessions of the corresponding user to ensure the correct configuration of the wireless subscription. For each subscribed PDU session, the service multiplexer (e.g., VLAN) used on the wired access is also configured. In some embodiments, the OSS (or ACS340) can issue a request via the NEF 390 to ensure such configuration of the corresponding wireless subscription. The NEF 390 can check the right to issue such a request. The NEF 390 can forward the request to the UDM (375). The UDM 375 can update the SM (session management) subscription data in the UDR 370 of the corresponding user with the list of subscribed PDU session selectors (DNN, S-NSSAI). If the PCF 330 knows that the terminal device (here, the W-AGF 320 representing the terminal FN-RG) is reachable, the PCF 330 can check whether the policy information such as the URSP configuration on the W-AGF 320 is aligned. The 5G core network supports an API that can be used to configure the mapping between the service multiplexer (e.g., VLAN) used on the V (wired) interface of the W-AGF and the PDU session subscription parameters (e.g., DNN, Single Network Slice Selection Assistance Information (S-NSSAI)). This API can be used by the ACS340 or the OSS.

[0065] The PCF 330 sends 4015 the first information to the W-AGF 320. In some embodiments, the first information may be sent in a URSP policy. If the first information is sent in a URSP policy, it may reuse the traffic filter information in the URSP, noting that even if the USRP is involved in an IP type PDU session, the URSP involving the Ethernet header must be sent for the FN-RG 315. Table 1 below shows the reused traffic filter information in the URSP. It should be noted that the headers shown in Table 1 are only examples.

[0068]

[0069] The FN-RG 315 detects 4020 application traffic and maps 4025 the application to a traffic multiplexer used on the wired access based on the second information. The application may include one or more of: IP Multimedia Subsystem (IMS) Voice, Internet Protocol Television (IPTV), Internet. In some embodiments, the traffic multiplexer used on the wired access of the FN-RG 315 may correspond to a VLAN. The FN-RG 315 sends 4030 a request for a wired data session on the mapped traffic multiplexer used on its wired access W-AGF.

[0070] The wireless subscription received from the FN-RG 315 may trigger a request to establish a protocol data unit (PDU) session. The W-AGF 320 maps 4035 the traffic multiplexer used on the wired access of the FN-RG 315 to the wireless data session selector based on the first information. The data session selector may refer to a data network name. Alternatively or additionally, the data session selector may refer to a slice identifier. The W-AGF 320 sends 4040 a request for a wireless data session with the selector to the core network.

[0071] In some embodiments, ACS 340 may send other provisioning information (hereinafter referred to as "third information") to 5G-RG 310. The third information can be used for mapping from wireless quality of service (QoS) to wired QoS. In some embodiments, the 3GPP driver in 5G-RG310 can map uplink traffic to 3GPP QoS flows based on NAS SM signaling received from 5GC. The 3GPP QoS flow then needs to be mapped to BBF QoS. Therefore, the provisioning information sent by ACS 340 to 5G-RG 310 can be extended to provide a mapping from 3GPP 5QI (defining the main parameters of 3GPP QoS) to wired line QoS parameters (e.g., IEEE802.1p priority or DSCP Diffserv code point as defined in the IETF specification).

[0072] Figure 5 A flow chart of a method 500 according to an embodiment of the present disclosure is shown. The method 500 may be implemented at any suitable device. For illustration purposes only, the method 500 is described as being implemented at the W-AGF 320 .

[0073] At block 510, the W-AGF 320 obtains first information from the PCF 330. The first information is about a wireless subscription for mapping from a traffic multiplexer used in a wired access to a wireless data session selector. The wireless subscription is associated with the wired access.

[0074] In some embodiments, the first information may be sent in a URSP policy, and the W-AGF 320 may extract the first information from the URSP policy. If the first information is sent in a URSP policy, it may reuse the traffic filter information in the URSP, noting that even if the USRP is involved in an IP type PDU session, a URSP involving an Ethernet header must be sent for the FN-RG 315.

[0075] At block 520, W-AGF 320 receives traffic within a traffic multiplexer used in wired access from FN-RG 315. Based on the second information, application traffic has been mapped to a traffic multiplexer (e.g., VLAN) used in wired access by FN-RG 315. The second information can be used to map an application to a traffic multiplexer.

[0076] At block 530, W-AGF 320 maps the traffic multiplexer used in the wired access to the wireless data session selector based on the first information. The data session selector may refer to a data network name. Alternatively or additionally, the data session selector may refer to a slice identifier.

[0077] At block 540, the W-AGF 320 sends a request for a wireless data session based on the wireless data session selector to the core network. Traffic received from the FN-RG 315 may trigger a request to establish a protocol data unit (PDU) session.

[0078] Figure 6 A flow chart of a method 600 according to an embodiment of the present disclosure is shown. The method 600 may be implemented at any suitable device. For illustration purposes only, the method 600 is described as being implemented at the PCF 330.

[0079] At block 610, the PCF 330 obtains first information from the ACS 340. The first information is about a wireless subscription for mapping from a traffic multiplexer used in wired access to a wireless data session selector. Alternatively, the first information may be about a wireless subscription for mapping from a traffic multiplexer used in wired access to a prioritized list of wireless data session selectors.

[0080] In some embodiments, the first information may not be sent directly from the ACS 340 to the PCF 330. In some embodiments, the ACS 340 or the operating system OSS may send the first information to the UDM 375 via the NEF 390. The UDM 375 may store the first information in the UDR 370. The UDR may notify the PCF 330 that the policy data about the wireless subscription it serves has changed, and may access the UDR 370 to obtain the first information. In this way, an indirect interaction between the ACS 340 and the PCF 330 is completed. In this way, a new application program interface (API) in the UDM 375, the UDR 370, the NEF 390, and the ACS 340 is defined as part of the mapping from the wireless subscription to the data session.

[0081] For example, in some embodiments, the Operation Support System (OSS) can utilize the list of subscribed PDU sessions of the corresponding user to ensure the correct configuration of the wireless subscription. For each subscribed PDU session, the service multiplexer (e.g., VLAN) used on the wired access is also configured. In some embodiments, the OSS (or ACS 340) can issue a request via the NEF 390 to ensure such configuration of the corresponding wireless subscription. The NEF 390 can check the right to issue such a request. The NEF 390 can forward the request to the UDM (375). The UDM 375 can update the SM subscription data in the UDR 370 of the corresponding user with the list of subscribed PDU sessions (DNN, S-NSSAI). If the PCF 330 knows that the terminal is reachable, the PCF 330 can check whether the URSP configuration on the UE is aligned.

[0082] At block 620, the PCF 330 transmits first information to the W-AGF 320. The first information is about a wireless subscription for mapping from a traffic multiplexer used in a wired access to a wireless data session selector. The wireless subscription is associated with the wired access.

[0083] In some embodiments, the first information may be sent in a URSP policy. If the first information is sent in a URSP policy, it may reuse the traffic filter information in the URSP. Note that even if the USRP is involved in an IP type PDU session, a URSP involving an Ethernet header must be sent for the FN-RG315.

[0084] Figure 7 A flow chart of a method 700 according to an embodiment of the present disclosure is shown. The method 700 may be implemented at any suitable device. For illustration purposes only, the method 700 is described as being implemented at the FN-RG 310.

[0085] At block 710, the FN-RG 315 receives second information from the ACS 340. The second information may be used to map wireless subscriptions to traffic multiplexers.

[0086] At block 720, if the FN-RG 315 detects application traffic, the FN-RG 315 maps the application traffic to a traffic multiplexer based on the second information. The application may include one or more of: IP Multimedia Subsystem (IMS) voice, Internet Protocol Television (IPTV), Internet. In some embodiments, the traffic multiplexer may correspond to a VLAN.

[0087] At box 730, FN-RG315 sends 4030 the wired data session request to W-AGF 320 on the mapped traffic multiplexer. At box 740, 5G-RG 310 receives third information from ACS 340. Other information can be used for mapping from wireless quality of service (QoS) to wired QoS. In some embodiments, the 3GPP driver in 5G-RG 310 can map uplink traffic to 3GPP QoS flows based on NAS SM signaling received from 5GC. The 3GPP QoS flow then needs to be mapped to BBF QoS. Therefore, the rules can be extended to provide a mapping from 3GPP5QI (the main parameter that defines 3GPP QoS) to wired line QoS parameters (e.g., IEEE802.1p priority).

[0088] Figure 8 A flow chart of a method 800 according to an embodiment of the present disclosure is shown. The method 800 may be implemented at any suitable device. For illustration purposes only, the method 800 is described as being implemented at the ACS 340.

[0089] At block 810 , the ACS 340 determines second information. The second information may be used to map the wireless subscription to the traffic multiplexer. At block 820 , the ACS 340 sends the second information to the FN-RG 315 .

[0090] At block 830, the ACS 340 determines first information based on the second information. The first information is about wireless subscription for mapping from a traffic multiplexer used in wired access to a wireless data session selector.

[0091] At block 840, ACS 340 sends the first information to PCF 330. In some embodiments, the first information may not be sent directly from ACS 340 to PCF 330. In some embodiments, ACS 340 may communicate with PCF 330 through an existing API on ACS 340 to the OSS system. The OSS system should ensure coordination and be able to communicate with the 3GPP UDR. Wireless subscription is associated with wired access.

[0092] In some embodiments, ACS 340 may send the first information to UDM. UDM may store the first information in UDR 370. PCF 330 may have subscribed to UDR 370 for changes in the first information and obtains it through notification of changes in such information. In this way, indirect interaction between ACS 340 and PCF 330 is completed. In this way, new application program interfaces (APIs) in UDM, NEF 390, and ACS 340 are defined as part of the mapping from wired and wireless subscriptions.

[0093] In some embodiments, the ACS 340 may send the third information to the 5G-RG 310. The third information may be used for mapping from wireless quality of service (QoS) to wired QoS. In some embodiments, the 3GPP driver in the 5G-RG 310 may map uplink traffic to 3GPP QoS flows based on NAS SM signaling received from the 5GC. The 3GPP QoS flows then need to be mapped to the BBF QoS. Therefore, the rules may be extended to provide mapping from 3GPP 5QI (the main parameter that defines 3GPP QoS) to wired QoS parameters (e.g., IEEE 802.1p priority).
