Abstract
Exemplary embodiments of the present invention are directed to systems and methods for announcing a call to an access terminal in a wireless communications system. Receiving, at an access network, a request to call a given access terminal and determining whether a cluster to which the given access terminal belongs is known at the access network by querying a location database. The location database includes a list of access terminals and clusters, which themselves include sectors of the wireless communications system. Thereafter, transmitting an announce message announcing the requested call to the given access terminal based on the determination of whether the cluster is known to the access network.

A method of announcing a call to an access terminal in a wireless communications system, comprising:
- receiving, at an access network, a request to call a given access terminal;
- determining whether a cluster to which the given access terminal belongs is known at the access network by querying a location database, the location database including a list of access terminals with each listed access terminal stored in association with one of a plurality of clusters, each of the plurality of clusters including a plurality of sectors of the wireless communications system;
- and
- transmitting an announce message announcing the requested call to the given access terminal based on the determining step,
- wherein the access network maintains, in the location database, location estimates of access terminals configured to decode announce messages over a downlink control channel with more precision than access terminals that are not configured to decode announce messages over the downlink control channel.
A method of announcing a call to an access terminal in a wireless communications system, comprising:
- receiving, at an access network, a request to call a given access terminal;
- determining whether a cluster to which the given access terminal belongs is known at the access network by querying a location database, the location database including a list of access terminals with each listed access terminal stored in association with one of a plurality of clusters, each of the plurality of clusters including a plurality of sectors of the wireless communications system;
- and
- transmitting an announce message announcing the requested call to the given access terminal based on the determining step
- wherein the location database is based upon one or more route update messages received from access terminals within the wireless communications system, and
- wherein access terminals configured to decode announce messages over a downlink control channel transmit the route update messages more frequently than access terminals that are not configured to decode announce messages over the downlink control channel.
An apparatus configured to announce a call to an access terminal in a wireless communications system, comprising:
- means for receiving, at an access network, a request to call a given access terminal;
- means for determining whether a cluster to which the given access terminal belongs is known at the access network by querying a location database, the location database including a list of access terminals with each listed access terminal stored in association with one of a plurality of clusters, each of the plurality of clusters including a plurality of sectors of the wireless communications system;
- and
- means for transmitting an announce message announcing the requested call to the given access terminal based on the means for determining,
- wherein the access network maintains, in the location database, location estimates of access terminals configured to decode announce messages over a downlink control channel with more precision than access terminals that are not configured to decode announce messages over the downlink control channel.
An apparatus configured to announce a call to an access terminal in a wireless communications system, comprising:
- logic configured to receive, at an access network, a request to call a given access terminal;
- logic configured to determine whether a cluster to which the given access terminal belongs is known at the access network by querying a location database, the location database including a list of access terminals with each listed access terminal stored in association with one of a plurality of clusters, each of the plurality of clusters including a plurality of sectors of the wireless communications system;
- and
- logic configured to transmit an announce message announcing the requested call to the given access terminal based on the logic configured to determine,
- wherein the access network maintains, in the location database, location estimates of access terminals configured to decode announce messages over a downlink control channel with more precision than access terminals that are not configured to decode announce messages over the downlink control channel.
A non-transitory computer readable medium including instructions thereon that may be utilized by one or more processors, the instructions configured to announce a call to an access terminal in a wireless communications system, the instructions comprising:
- instructions to receive, at an access network, a request to call a given access terminal;
- instructions to determine whether a cluster to which the given access terminal belongs is known at the access network by querying a location database, the location database including a list of access terminals with each listed access terminal stored in association with one of a plurality of clusters, each of the plurality of clusters including a plurality of sectors of the wireless communications system;
- and
- instructions to transmit an announce message announcing the requested call to the given access terminal based on the instructions to determine,
- wherein the access network maintains, in the location database, location estimates of access terminals configured to decode announce messages over a downlink control channel with more precision than access terminals that are not configured to decode announce messages over the downlink control channel.
