Abstract
Disclosed are a method and apparatus for recovering an RRC connection, and a computer storage medium. The method includes a target base station receiving an RRC connection recovery request message sent by a terminal. The method also includes the target base station determining, according to a UE identifier in the RRC connection recovery request message, a first node served by the terminal, and acquiring a UE context from the first node. The UE context includes a first UE context at a first node side and a second UE context at a second node side. The method further includes the target base station sending an RRC connection recovery message to the terminal, so that the terminal recovers an RRC connection.
Claims12
A method for resuming a radio resource control (RRC) connection, comprising:
- receiving, by a target base station, an RRC connection resume request message sent by a terminal;
- determining, by the target base station, a master node in a dual connection network or a multi-connection network serving the terminal according to a user equipment (UE) identifier in the RRC connection resume request message, and obtaining, from the master node, both a first UE context on the master node and a second UE context on a secondary node in the dual connection network or the multi-connection network;
- and
- sending, by the target base station, an RRC connection resume message to the terminal, so as for the terminal to resume the RRC connection,
- wherein the terminal is a terminal in a first type of RRC inactive state, and the first type of RRC inactive state refers to a state which the terminal is in after all RRC connections are suspended,
- wherein the RRC connection resume request message comprises secondary cell group (SCG) configuration information or indication information of SCG configuration,
- wherein the method further comprises:
- sending, by the target base station, an S-KgNB to a secondary network node corresponding to the target base station.
A method for resuming an RRC connection, comprising:
- sending, by a terminal, an RRC connection resume request message to a target base station, so that the target base station determines a master node in a dual connection network or a multi-connection network serving the terminal according to a UE identifier in the RRC connection resume request message, and obtains from the master node, both a first UE context on the master node and a second UE context on a secondary node in the dual connection network or the multi-connection network;
- and
- receiving, by the terminal, an RRC connection resume message sent by the target base station, and then resuming the RRC connection,
- wherein the terminal is a terminal in a first type of RRC inactive state, and the first type of RRC inactive state refers to a state which the terminal is in after all RRC connections are suspended,
- wherein the RRC connection resume request message comprises SCG configuration information or indication information of SCG configuration,
- wherein the target base station further sends an S-KgNB to a secondary network node corresponding to the target base station.
An apparatus for resuming an RRC connection, comprising:
- a processor and a memory storing program instructions,
- wherein when the program instructions are executed by the processor, the apparatus is configured to:
- receive an RRC connection resume request message sent by a terminal;
- determine a master node in a dual connection network or a multi-connection network serving the terminal according to a UE identifier in the RRC connection resume request message, and obtain, from the master node, both a first UE context on the master node and a second UE context on a secondary node in the dual connection network or the multi-connection network;
- and
- send an RRC connection resume message to the terminal, so as for the terminal to resume the RRC connection,
- wherein the terminal is a terminal in a first type of RRC inactive state, and the first type of RRC inactive state refers to a state which the terminal is in after all RRC connections are suspended,
- wherein the RRC connection resume request message comprises secondary cell group (SCG) configuration information or indication information of SCG configuration,
- wherein the apparatus is further configured to:
- send an S-KgNB to a secondary network node corresponding to the target base station.
