Methods, apparatuses and computer readable media for optimizing radio resource control RRC connectivity

A wireless device for radio resource control (“RRC”) connectivity, comprising:

• a power source configured to provide power to an interface and processing circuitry;
• the interface configured to:
• transmit a RRC connection request message to a network node, the RRC connection request message is part of a first RRC connection protocol;
• transmit a second RRC connection request message to the network node, wherein the second RRC connection request message is part of a second RRC connection protocol;
• receive a responsive message from the network node, the response message is part of the first RRC connection protocol;
• receive an indication that the wireless device should suppress a RRC connection complete message that is part of the first RRC connection protocol;
• and
• the processing circuitry communicatively coupled to the interface, the processing circuitry configured to:
• determine that the RRC connection complete message should not be transmitted to the network node with respect to the first RRC connection protocol;
• suppress the transmittal of the RRC connection complete message to the network node with respect to the first RRC connection protocol;
• and
• wherein the interface is further configured to transmit a second RRC connection complete message to the network node wherein the second RRC connection complete message is part of the second RRC connection protocol, the second RRC connection complete message indicating that signaling for both the first RRC connection protocol and the second RRC connection protocol is complete.

A method performed by a network node for radio resource control (RRC) connectivity, the method comprising:

• receiving a first RRC connection request message from a wireless device, the RRC connection request message is part of a first RRC connection protocol;
• receiving a second RRC connection request message from the wireless device, wherein the second RRC connection request message is part of a second RRC connection protocol;
• determining that a second RRC connection protocol will be communicated in response to the first RRC connection protocol and that a RRC connection complete message can be suppressed with respect to the first RRC connection protocol;
• transmitting a responsive message to the wireless device, wherein the responsive message is part of the first RRC connection protocol;
• transmitting an indication to the wireless device that the wireless device should suppress the RRC connection complete message that is part of the first RRC connection protocol;
• and
• receiving a second RRC connection complete message from the wireless device wherein the second RRC connection complete message is part of the second RRC connection protocol, the second RRC connection complete message indicating that signaling for both the first RRC connection protocol and the second RRC connection protocol is complete.
