US 10,455,369 B2 · Subscription requirement indication for service

Abstract

A STA and method of providing a subscription policy are provided. The STA determines a subscription policy for a multicast, broadcast or unicast service and provides a policy comprising an indication that indicates active subscription (i.e. group joining is required) or no subscription (i.e. group joining is prohibited) or implicit subscription (i.e. group joining is implicit), dependent on network or subscription conditions. Updates to the policy are transmitted upon one or more thresholds are being reached. Subscribers re-subscribe to the service when the indication switches from implicit subscription to active subscription.

Dependent claims

An apparatus of a wireless communication station (STA) configured to operate as a publisher, the apparatus comprising:

memory;
and
processing circuitry, arranged to:
retrieve, from the memory, a subscription policy for a multicast service of the publisher, the subscription policy comprising an indication that is selectable from among:
active subscription/group joining required, in which a frame exchange between a subscriber and the publisher is to be used to subscribe the subscriber to the multicast service, and
active subscription/group joining prohibited, in which a frame exchange is avoided between the subscriber and the publisher for the subscriber to subscribe to the multicast service;
and
encode, for transmission in a Neighborhood Awareness Network (NAN) message, the indication to the subscriber to subscribe to the multicast service.

5 more elements

A method of communicating a subscription policy, the method comprising:

receiving from a publisher a subscription policy for a service in a Neighborhood Awareness Network (NAN), the subscription policy comprising an indication selectable from active subscription/group joining required, implicit subscription allowed, or active subscription/group joining prohibited, the subscription policy being updatable to provide a different indication;
and
subscribing to the service using the subscription policy indicated by the indication, the service selected from among a multicast service, a unicast service and a broadcast service,
wherein the method further comprises:
engaging in a frame exchange to subscribe to the multicast service when the indication indicates active subscription/group joining is required,
determining whether to engage in the frame exchange to subscribe to the multicast service when the indication indicates implicit subscription is allowed, and
avoiding the frame exchange to subscribe to the multicast service when the indication indicates active subscription is prohibited.

4 more elements

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a subscriber to configure the subscriber to:

receive, from a publisher in a Neighborhood Awareness Network (NAN), a subscription policy for a multicast service, the subscription policy comprising an indication selectable from active subscription/group joining required, implicit subscription allowed, or active subscription/group joining prohibited;
and
receive from a publisher a subscription policy update when a predetermined set of network or subscription conditions is met,
wherein the instructions further configure the subscriber to:
engage in a frame exchange to subscribe to the multicast service when the indication indicates active subscription/group joining is required,
determine whether to engage in the frame exchange to subscribe to the multicast service when the indication indicates implicit subscription is allowed, and
avoid the frame exchange to subscribe to the multicast service when the indication indicates active subscription is prohibited.
