Method and System for Discontinuous Reception De-Synchronization Detection
A method and apparatus for discontinuous reception desynchronization detection between an enhanced Node B and a user equipment, the method having the steps of: waiting for a predefined event to occur; and upon the predefined event occurring, sending a message from one of the enhanced Node B and the user equipment to the other of the enhanced Node B and user equipment, wherein the message contains one of a request for discontinuous reception period information or discontinuous reception period information, the discontinuous reception period information or discontinuous reception period information being utilized to detect desynchronization.
1 . A method for detecting a discontinuous reception (DRX) de-synchronization between a network and a user equipment (UE), the method comprising the steps of:
sending a request message from the network to the UE, wherein said request message includes a request for a DRX period information of the UE;
receiving a response message from the UE to the network, wherein said response message includes the DRX period information of the UE;
detecting the DRX de-synchronization between the network and the UE; and
recovering from the DRX de-synchronization between the network and the UE.
2 . The method of claim 1 further comprises comparing the DRX period information of the UE received in the response message with a DRX period information of the network.
3 . The method of claim 1 , wherein the recovering comprises sending a continuous communication command from the network to the UE.
4 . The method of claim 3 , wherein the recovering further comprises receiving a reply to the continuous communication command from the UE to the network.
5 . A method for detecting a discontinuous reception (DRX) de-synchronization between a network and a user equipment (UE), the method comprising the steps of:
receiving a request message from the network to the UE, wherein said request message includes a request for DRX de-synchronization detection;
detecting the DRX de-synchronization between the network and the UE;
sending a response message from the UE to the network, wherein said response message includes a DRX de-synchronization detection flag, if detecting the DRX de-synchronization; and
recovering from the DRX de-synchronization between the network and the UE.
6 . The method of claim 5 , wherein said request message includes a DRX period information of the network.
7 . The method of claim 6 comprises comparing the DRX period information of the network with a DRX period information of the UE.
8 . The method of claim 5 , wherein the recovering comprises receiving a continuous communication command from the network to the UE.
9 . The method of claim 8 , wherein the recovering further comprises sending a reply to the continuous communication command from the UE to the network.
10 . A network adapted to detect a discontinuous reception (DRX) de-synchronization between the network and a user equipment (UE), the network comprising a communications subsystem and a processor, wherein the processor is configured to:
send a request message from the network to the UE, wherein said request message includes a request for a DRX period information of the UE;
receive a response message from the UE to the network, wherein said response message includes the DRX period information of the UE;
detect the DRX de-synchronization between the network and the UE; and
recover from the DRX de-synchronization between the network and the UE.
11 . The network of claim 10 , wherein the processor is further configured to compare the DRX period information of the UE received in the response message with a DRX period information of the network.
12 . The network of claim 10 , wherein the recovering comprises the processor being configured to send a continuous communication command from the network to the UE.
13 . The network of claim 12 , wherein the recovering further comprises the processor being configured to receive a reply to the continuous communication command from the UE to the network.
14 . A user equipment (UE) adapted to detect a discontinuous reception (DRX) de-synchronization between a network and the UE, the UE comprising a communications subsystem and a processor, wherein the processor is configured to:
receive a request message from the network to the UE, wherein said request message includes a request for DRX de-synchronization detection;
detect the DRX de-synchronization between the network and the UE;
send a response message from the UE to the network if detecting the DRX de-synchronization, wherein said response message includes a DRX de-synchronization detection flag; and
recover from the DRX de-synchronization between the network and the UE.
15 . The UE of claim 14 , wherein said request message includes a DRX period information of the network.
16 . The UE of claim 15 comprises the processor being configured to compare the DRX period information of the network with a DRX period information of the UE.
17 . The method of claim 16 , wherein the response from the user equipment to the enhanced Node B containing the desynchronization detected flag is in response to said message, upon detection of desynchronization at the user equipment.
18 . The UE of claim 17 , wherein the recovering further comprises the processor being configured to send a reply to the continuous communication command from the UE to the network.
