RRC CONNECTION REESTABLISHMENT IN A WIRELESS COMMUNICATION NETWORK |
| 摘要 |
Methods for facilitating Radio Resource Control (RRC) connection reestablishment between a communication device and a target communication node in a wireless communication network and the respective device and node are disclosed. The method in the communication device comprises generating a RRC connection reestablishment request message which includes a Physical Cell Identifier (PCI) of a source cell to which the communication device attaches before the RRC connection reestablishment and transmitting the RRC connection reestablishment request message to the target communication node. The communication device receives from the target communication node a first RRC connection reestablishment rejection message which includes a first indicator indicating need of first information for the RRC connection reestablishment, detects the first indicator from the first RRC connection reestablishment rejection message, generates a first communication device information response message which includes the first information and transmits the communication device information response message to the target communication node. |

1. A method for facilitating a communication device to reestablish a Radio Resource Control (RRC) connection with a target communication node in a wireless communication network, the method comprising:
generating a RRC connection reestablishment request message which includes a Physical Cell Identifier (PCI) of a source cell to which the communication device attaches before the RRC connection reestablishment and transmitting the RRC connection reestablishment request message to the target communication node; receiving from the target communication node a first RRC connection reestablishment rejection message which includes a first indicator indicating need of first information for the RRC connection reestablishment; detecting the first indicator from the first RRC connection reestablishment rejection message; and generating a first communication device information response message which includes the first information and transmitting the communication device information response message to the target communication node. |
