Abstract
In one embodiment, an apparatus can include: (i) a layer 3 point of attachment having an input configured to receive handoff indicative information from a mobile device substantially in parallel with the handoff indicative information being received in a layer 2 handoff function; and (ii) logic configured to perform a handoff facilitating action in response to the handoff indicative information.
Claims20
An apparatus, comprising:
- one or more processors;
- and
- logic encoded in one or more tangible media for execution by the one or more processors, and when executed operable to:
- receive a message from a mobile device in a layer 3 point of attachment, the message having handoff indicative information to provide notice to the layer 3 point of attachment from the mobile device substantially in parallel and at substantially a same time with the handoff indicative information being received in a layer 2 handoff function block, wherein the handoff indicative information comprises a cell site identifier and a cell signal strength indicator;
- send a request for other available layer 3 points of attachment to a mobility anchor in response to the received message in the layer 3 point of attachment;
- receive a list of suitable layer 3 points of attachment from the mobility anchor in response to the request;
- and
- arrange one or more paths to facilitate a handoff of the mobile device to a new layer 3 point of attachment in the received list.

A method, comprising:
- receiving a message from a mobile device in a layer 3 point of attachment, the message having handoff indicative information to provide notice to the layer 3 point of attachment from the mobile device substantially in parallel and at substantially a same time with the handoff indicative information being received in a layer 2 handoff function block, wherein the handoff indicative information comprises a cell site identifier and a cell signal strength indicator;
- sending a request for other available layer 3 points of attachment to a mobility anchor in response to the received message in the layer 3 point of attachment;
- receiving a list of suitable layer 3 points of attachment from the mobility anchor in response to the request;
- and
- arranging one or more paths to facilitate a handoff of the mobile device to a new layer 3 point of attachment in the received list.
2 more elements
A non-transitory computer-readable storage medium having one or more instructions stored thereon, the one or more instructions being for execution by a processor, the storage medium comprising:
- one or more instructions for receiving a message from a mobile device in a layer 3 point of attachment, the message having handoff indicative information to provide notice to the layer 3 point of attachment from the mobile device substantially in parallel and at substantially a same time with the handoff indicative information being received in a layer 2 handoff function block, wherein the handoff indicative information comprises a cell site identifier and a cell signal strength indicator;
- one or more instructions for sending a request for other available layer 3 points of attachment to a mobility anchor in response to the received message in the layer 3 point of attachment;
- one or more instructions for receiving a list of suitable layer 3 points of attachment from the mobility anchor in response to the request;
- and
- one or more instructions for arranging one or more paths to facilitate a handoff to a new layer 3 point of attachment in the received list.
2 more elements
A system, comprising:
- a layer 3 point of attachment having:
- one or more processors;
- and
- logic encoded in one or more tangible media for execution by the one or more processors, and when executed operable to:
- receive handoff indicative information from a mobile device, the layer 3 point of attachment being configured to perform a handoff facilitating action in response to the handoff indicative information, wherein the handoff indicative information comprises a cell site identifier and a cell signal strength indicator;
- send a request for other available layer 3 points of attachment to a mobility anchor in response to the received handoff indicative information in the layer 3 point of attachment;
- receive a list of suitable layer 3 points of attachment from the mobility anchor in response to the request;
- and
- arrange one or more paths to facilitate a handoff of the mobile device to a new layer 3 point of attachment in the received list;
- and
- a layer 2 handoff function block coupled to the layer 3 point of attachment,
- wherein the layer 2 handoff function block and the layer 3 point of attachment are configured to receive the handoff indicative information substantially in parallel and at substantially a same time.
9 more elements
