Abstract
A delegate wireless terminal can receive and store messages sent to it by a receiving network node. The wireless terminal can identify a message label based on a mapping for the received message. A transmitting network node can transmit a message label to a receiving network node across a backhaul link. The receiving network node can transmit a message label to the wireless terminal. The wireless terminal can identify a stored message that corresponds to the received message label, and send the corresponding message to the receiving network node. The receiving network node can then transmit the message to its intended destination.
Claims18
A method performed by a first wireless terminal, comprising:
- monitoring a transmission from a network node to a second wireless terminal, wherein the transmission comprises a first label;
- based on the transmission, identifying a first message based on the first label and a mapping relationship, the first message being stored in the first wireless terminal prior to the transmission;
- transmitting the first message to the second wireless terminal;
- receiving a second message from the network node;
- determining a second label corresponding to the second message, based on the mapping relationship;
- determining whether the second label is prestored in the first wireless terminal;
- in response to the second label being prestored in the first wireless terminal, comparing the second message to the first message;
- and
- in response to the second label being the same as the first label and the second message being different from the first message, maintaining the prestored first message, wherein the second message is not saved by the first wireless terminal.
A first wireless terminal, comprising:
- a memory;
- and
- a processor configured to execute computer instructions to:
- monitor a transmission from a network node to a second wireless terminal, wherein the transmission comprises a first label;
- based on the transmission, identify a first message based on the first label and a mapping relationship, the first message being stored in the first wireless terminal prior to the transmission;
- transmit the first message to the second wireless terminal;
- receive a second message from the network node;
- determine a second label corresponding to the second message, based on the mapping relationship;
- determine whether the second label is prestored in the first wireless terminal;
- in response to the second label being prestored in the first wireless terminal, compare the second message to the first message;
- and
- in response to the second label being the same as the first label and the second message being different from the first message, maintain the first message in the memory, wherein the second message is not saved in the memory.
A non-transitory computer-readable medium comprising a computer program code that, when executed by a processor coupled to a first wireless terminal, causes the first wireless terminal to perform operations comprising:
- monitoring a transmission from a network node to a second wireless terminal, wherein the transmission comprises a first label;
- based on the transmission, identifying a first message based on the first label and a mapping relationship, the first message being stored in the first wireless terminal prior to the transmission;
- transmitting the first message to the second wireless terminal;
- receiving a second message from the network node;
- determining a second label corresponding to the second message, based on the mapping relationship;
- determining whether the second label is prestored in the first wireless terminal;
- in response to the second label being prestored in the first wireless terminal, comparing the second message to the first message;
- and
- in response to the second label being the same as the first label and the second message being different from the first message, maintaining the prestored first message, wherein the second message is not saved by the first wireless terminal.
