Radio resource connection (rrc) establishment for wireless systems

An item of user equipment (UE), the UE being capable of performing a handoff from a source extended Node-B (e-NB) to a target e-NB, the UE comprising:

• wireless communication circuitry;
• means for detecting a radio link failure (RLF) between the UE and the source e-NB by the UE coupled to the wireless communication circuitry;
• and
• means for maintaining an active communication service at a service layer of the UE after detecting the RLF and as the UE performs the handoff from the source e-NB to the target e-NB such that the communication service remains continuously active during the handoff, the communication service supporting a first communication between the UE and a third party.

A computer program product, comprising:

• a computer-readable medium comprising:
• a set of one or more instructions for determining whether a radio link failure (RLF) between user equipment (UE) and a source extended Node-B (e-NB);
• and
• a set of one or more instructions for performing a wireless handoff for the UE while maintaining an active communication service at a service layer of the UE after detecting the RLF and as the UE performs the handoff from the source e-NB to the target e-NB such that the communication service remains continuously active during the handoff, the communication service supporting a first communication between the UE and a third party.

A method for performing a wireless handoff for user equipment (UE) as the UE performs a handoff from a source extended Node-B (e-NB) to a target e-NB, the method comprising:

• receiving a connection request message from the UE, the connection request message being received after a radio link failure of a communication link between the UE and source e-NB;
• forwarding the connection request message to a core communication network;
• receiving a connection setup message from the core network in response to the forwarded connection request message;
• and
• forwarding the connection setup message to the UE such that an active communication service at a service layer of the UE remains continuously active during the handoff while communication payload data transfer is re-established between the UE and a third party via the target e-NB.

An extended Node-B (e-NB) capable of being used for handoff of user equipment (UE) from a source extended Node-B (e-NB) to a target e-NB, the e-NB comprising:

• wireless communication circuitry;
• processing circuitry coupled to the wireless communication circuitry, the processing circuitry being configured to:
• receive a connection request message from the UE, the connection request message being received after a radio link failure of a communication link between the UE and source e-NB;
• forward the connection request message to a core communication network;
• receive a connection setup message from the core network in response to the forwarded connection request message;
• and
• forward the connection setup message to the UE such that an active communication service at a service layer of the UE remains continuously active during the handoff while communication payload data transfer is re-established between the UE and a third party via the target e-NB.
