Abstract
The present disclosure relates in general to cellular radio network communication. In one of its aspects, the technology presented herein concerns a method implemented in a receiver for detecting delayed or lost signaling messages. The signaling messages are receivable both over a Master Node, MN, and a Secondary Node, SN, and detecting delayed or lost signaling messages is based on sequence number. The method comprises detecting a gap in sequence numbers of received signaling messages.

1-28. (canceled)
A method implemented in a receiver for detecting delayed or lost control signaling messages, wherein the signaling messages are Radio Resource Control (RRC) messages, and wherein the signaling messages are receivable both over a Master Node (MN) and a Secondary Node (SN) and wherein detecting delayed or lost signaling messages is based on sequence numbers, wherein the RRC message further includes a message type identifier, which identifies whether said message must be processed in-sequence with previously transmitted messages, the method comprising:
- detecting a gap in sequence numbers of received signaling messages, and
- determining whether there is a need to initiate a recovery procedure or if a current RRC command can be executed without waiting for a former message.
A receiver for detecting delayed or lost control signaling messages wherein the signaling messages are Radio Resource Control (RRC) messages, and, wherein the signaling messages are receivable both over a Master Node (MN) and a Secondary Node (SN) and wherein detecting delayed or lost signaling messages is based on sequence number, wherein the RRC message further includes a message type identifier, which identifies whether said message must be processed in-sequence with previously transmitted messages, said receiver comprising RF transceiver circuitry, device readable medium and processing circuitry, wherein the processing circuitry is configured to control the device readable medium and transceiver circuitry to:
- detect a gap in sequence numbers of received messages, and
- determining whether there is a need to initiate a recovery procedure or if a current RRC command can be executed without waiting for a former message
A method implemented in a transmitter for transmitting control signaling messages, wherein the signaling messages are Radio Resource Control (RRC) messages, wherein the signaling messages are transmittable both over a Master Node (MN) and a Secondary Node (SN), the method comprising:
- assigning sequence numbers to the signaling messages;
- including a message type identifier in each transmitted RRC message, wherein the RRC message type identifier identifies whether the concerned message must be processed in-sequence with previously transmitted messages;
- and
- transmitting the signaling messages to a receiver.
A transmitter for transmitting control signaling messages, wherein the signaling messages are Radio Resource Control (RRC) messages, wherein the signaling messages are transmittable both over a Master Node (MN) and a Secondary Node (SN), said transmitter comprising RF transceiver circuitry, device readable medium and processing circuitry, wherein the processing circuitry is configured to control the device readable medium and transceiver circuitry to:
- assign sequence numbers to the signaling messages;
- include a message type identifier in each transmitted RRC message, wherein the RRC message type identifier identifies whether the concerned message must be processed in-sequence with previously transmitted messages, and
- transmit the signaling messages to a receiver.
