Abstract

Embodiments of the disclosure provide a method, device and computer readable medium for coordination between wireline and wireless policy controllers. According to embodiments of the present disclosure, the service controller is able to coordinate between information about a wireless subscription for mapping from a traffic multiplexer used in a wireline access to a wireless data session selector and information sent to a wireline Residential Gateway device about mapping application traffic to a traffic multiplexer used in a wireline access.

First claim

What is claimed is:

1. A wireless access gateway function (W-AGF) comprising:
at least one processor; and a memory coupled to the at least one processor, the memory storing instructions therein, the instructions, when executed by the at least one processor, causing the W-AGF to perform operations, the operations comprising:
obtaining from a policy control function (PCF) of a core network, first information comprising mapping of a traffic multiplexer used in connecting a fixed network-residential gateway (FN-RG) to a wireline access interface of the W-AGF to a list of wireless data session selectors;
receiving traffic from the FN-RG via the traffic multiplexer and the wireline access interface of the W-AGF;
mapping the traffic receive form the FN-RG via the traffic multiplexer and the wireline access interface to a wireless data session selector included in the list of wireless data session selectors based on the first information, wherein respective wireless data session selectors included in the list of wireless data session selectors comprise at least one of: Data Network Name (DNN) or a slice identifier of a network slice for a wireless data session;
transmitting, to a core network, a request for the wireless data session based on the wireless data session selector; and
transmitting the traffic via the wireless data session to the core network.

2. The W-AGF of claim 1 , wherein the traffic multiplexer corresponds to a Virtual Local Area Network (VLAN).

3. The W-AGF of claim 1 , wherein the obtaining the first information comprises:
receiving user equipment route selection policy (URSP) from the PCF; and
extracting the first information from the URSP.

4. The W-AGF of claim 1 , wherein the transmitting the wireless data session request comprises transmitting non-access stratum signaling comprising a request to register to and establish the wireless data connection with the core network.

5. A policy control function (PCF), comprising:
at least one processor; and
a memory coupled to the at least one processor, the memory storing instructions therein, the instructions, when executed by the at least one processor, causing the PCF to perform operations, the operations comprising:
receiving, from an auto-configuration server (ACS), first information comprising mapping from a traffic multiplexer used in a wireline access to a list of wireless data session selectors, wherein respective wireless data selectors included in the list of wireless data session selectors comprise—at least one of a Data Network name or a slice identifier for a wireless data session;
determining whether the W-AGF is reachable;
determining, based on determining that the W-AGF is reachable, whether policy information between the W-AGF and a fixed network -residential gateway (FN-RG) is aligned; and
transmitting a user equipment (UE) route selection policy (URSP) including the first information to a wireless access gateway function (W-AGF) based on determining that the policy information between the W-AGF and the FN-RG is aligned.

6. The PCF of claim 5 , wherein the traffic multiplexer corresponds to a Virtual Local Area Network (VLAN).

7. The PCF of claim 5 , wherein the receiving the first information comprises receiving the first information from the ACS via a data repository storing a user related subscription comprising the first information.

8. A fixed network-residential gateway (FN-RG), comprising:
at least one processor; and
a memory coupled to the at least one processor, the memory storing instructions therein, the instructions, when executed by the at least one processor, causing the FN-RG to perform operations, the operations comprising:
receiving, second information from an auto-configuration (ACS), the second information comprising a mapping of an application comprising at least one of internet, internet protocol (IP) multimedia subsystem (IMS) voice or IP television (IPTV) to a traffic multiplexer corresponding to a virtual local area network (VLAN) used in connecting the FN-RG to a wireline access interface of a wireless access gateway function (W-AGF);
in response to detecting application traffic for the application comprising at least one of the internet, IMS voice or IPTV, mapping the application traffic to the traffic multiplexer corresponding to the VLAN based on the second information;
transmitting, based on the second information, a wireline data session request to W-AGF via the traffic multiplexer used in connecting the FN-RG to a wireline access interface of the W-AGF, the wireline data session for establishing a wireline data session between the FN-RG and the W-AGF; and
receiving third information from the ACS, the third information comprising a mapping of wireless quality of service (QoS) parameters for a wireless data session between the W-AGF and a core network of a communication network to wireline QoS parameters of the wireless data session.

9. The FN-RG of claim 8 , wherein the wireless quality of service parameters corresponds to a 5G QoS indicator.

10. An auto-configuration server (ACS), comprising:
at least one processor; and
a memory coupled to the at least one processor, the memory storing instructions therein, the instructions, when executed by the at least one processor, causing the ACS to perform operations, the operations comprising:
determine second information comprising a mapping of an application comprising at least one of internet, internet protocol (IP) multimedia subsystem (IMS) voice or IP television (IPTV) to a traffic multiplexer corresponding to a virtual local area network (VLAN) used in connecting a network-residential gateway (FN-RG) to a wireline access interface of a wireless access gateway function (W-AGF);
transmitting the second information to a FN-RG;
determining, based on the second information, first information comprising a mapping from the traffic multiplexer corresponding to the VLAN used in connecting a wireline access interface of the W-AGF to a wireless data session selector, to ensure mapping between the first information and the second information, wherein the first information comprises reused traffic filter information from a user equipment route selection policy (URSP); and
transmitting the first information to a policy control function (PCF).

11. The fourth ACS of claim 10 , wherein the ACS is further caused to: transmit the first information to the PCF via a data repository storing user related subscriptions.

12. The ACS of claim 10 , wherein the operations further comprise mapping the traffic multiplexor used in connecting the FN-RG to the wireline access interface of the W-AGF to one or more protocol data unit (PDU) session subscription parameters, using the first information and an application programming interface (API) supported by a core network.
