Abstract
A method and apparatus for enabling handover of a mobile device in a network supporting a single unacknowledged control block on a control channel, where if channel conditions exceed a threshold, the method sends, from a mobile device, a request or message utilizing a control channel; and if channel conditions do not exceed the threshold, the method delays the sending of the request or message to permit a handover message to use the control channel.
Claims26
A method for enabling handover of a mobile device in a network, the method comprising:
- if channel conditions exceed a threshold, sending, from a mobile device, a request or message utilizing a control channel;
- and
- if channel conditions do not exceed the threshold, delaying the sending of the request or message to permit a handover message to use the control channel.
A mobile device configured for enabling handover in a network, the mobile device comprising:
- a processor;
- a communications subsystem;
- and
- memory,
- wherein the processor, communications subsystem and memory cooperate to:
- if channel conditions exceed a threshold, send a request or message utilizing a control channel;
- and
- if channel conditions do not exceed the threshold, delay the sending of the request or message to permit a handover message to use the control channel.
A method for enabling handover of a mobile device at a network element, the method comprising:
- if channel conditions exceed a threshold, sending, from the network element, a request or message utilizing a control channel;
- and
- if channel conditions do not exceed the threshold, prioritizing a handover message over the request or message, or sending the handover message from the network element to the mobile device.
A network element configured for enabling handover of a mobile device, the network element comprising:
- a processor;
- a communications subsystem;
- and
- memory,
- wherein the processor, communications subsystem and memory cooperate to:
- if channel conditions exceed a threshold, send, from the network element, a request or message utilizing a control channel;
- and
- if channel conditions do not exceed the threshold, prioritize a handover message over the request or message, or send the handover message from the network element to the mobile device.
