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.
Claims15
An apparatus, comprising:
- 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 block;
- and
- logic configured to perform a handoff facilitating action in response to the handoff indicative information.
A method, comprising:
- receiving a message in a layer 3 point of attachment from a mobile device, the message having handoff indicative information;
- sending a request for other available layer 3 points of attachment to a mobility anchor;
- receiving a list of suitable layer 3 points of attachment from the mobility anchor;
- and
- arranging one or more paths to facilitate a handoff to a new layer 3 point of attachment in the list.

A system, comprising:
- a layer 3 point of attachment having an input configured to receive handoff indicative information about a mobile device, the layer 3 point of attachment having logic configured to perform a handoff facilitating action in response to the handoff indicative information;
- 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.
A means for layer 3 handoff assistance, comprising:
- a means for receiving a message in a layer 3 point of attachment from a mobile device, the message having handoff indicative information;
- a means for sending a request for other available layer 3 points of attachment to a mobility anchor;
- a means for receiving a list of suitable layer 3 points of attachment from the mobility anchor;
- and
- a means for arranging one or more paths to facilitate a handoff to a new layer 3 point of attachment in the list.
