Abstract
In an example, an access terminal sends a group member report to an access network, the group member report indicating a location of the access terminal and at least one multicast group, the group member report being sent before a multicast session associated with the multicast group is initiated, determines a location update rule, the location update rule being a manner in which to report location updates of the access terminal to the access network and reports location updates of the access terminal to the access network based on the determined location update rule.
Claims27
A method of operating a radio access network portion of a wide area access network, comprising:
- forming a group member list, the group member list including a list of access terminals, at least one multicast group associated with each of the listed access terminals, a location associated with each of the listed access terminals and a time-stamp indicating a time at which each location was last reported to the wide area access network;
- and
- updating the group member list based on at least one report sent from at least one access terminal.
A radio access network portion of a wide area access network, comprising:
- a processor and memory configured to:
- form a group member list, the group member list including a list of access terminals, at least one multicast group associated with each of the listed access terminals, a location associated with each of the listed access terminals and a time-stamp indicating a time at which each location was last reported to the wide area access network;
- and
- update the group member list based on at least one report sent from at least one access terminal.
A radio access network portion of a wide area access network, comprising:
- means for forming a group member list, the group member list including a list of access terminals, at least one multicast group associated with each of the listed access terminals, a location associated with each of the listed access terminals and a time-stamp indicating a time at which each location was last reported to the wide area access network;
- and
- means for updating the group member list based on at least one report sent from at least one access terminal.
A non-transitory computer-readable medium including program code stored thereon, the program code configured to operate within a radio access network portion of a wide area access network including a plurality of sectors, comprising:
- program code to form a group member list at an access network, the group member list including a list of access terminals, at least one multicast group associated with each of the listed access terminals, a location associated with each of the listed access terminals and a time-stamp indicating a time at which each location was last reported to the wide area access network;
- and
- program code to update the group member list based on at least one report sent from at least one access terminal.
