Abstract

The present application discloses a system and an apparatus. A terminal send uplink radio resource control (RRC) signaling carrying an enhanced state transition capability of the terminal to the controlling node, the controlling node generates state transition indication information according to the enhanced state transition capability of the terminal, and sends the state transition indication information and information about a target RRC state to the terminal, and the terminal transits from a current RRC state to the target RRC state according to the state transition indication information and the information about the target RRC state.

What is claimed is: 
     
         1 . An apparatus of a terminal, comprising:
 a transmitter, configured to send uplink radio resource control (RRC) signaling carrying an enhanced state transition capability of the terminal to a controlling node;   a receiver, configured to receive state transition indication information and information about a target RRC state from the controlling node; and   a processor, configured to enable the terminal to transit from a current RRC state to the target RRC state according to the state transition indication information and the information about the target RRC state.   
     
     
         2 . The apparatus according to  claim 1 , wherein the transmitter is further configured to:
 before the processor enables the terminal to transit from the current RRC state to the target RRC state, send signaling connection release indication information carrying an information element to the controlling node, wherein the information element represents that a signaling connection release indication cause is set to the terminal requested packet switch data session end.   
     
     
         3 . The apparatus according to  claim 2 , wherein the receiver is further configured to receive radio link control acknowledgement information from the controlling node according to the signaling connection release indication information. 
     
     
         4 . The apparatus according to  claim 1 , wherein the receiver is further configured to receive reconfiguration signaling from the controlling node, and the reconfiguration signaling carries the state transition indication information and the information about the target RRC state. 
     
     
         5 . An apparatus of a terminal, comprising:
 one or more processors coupled with a non-transitory storage medium storing executable instructions which, when executed by the one or more processors, cause the terminal to:
 send uplink radio resource control (RRC) signaling carrying an enhanced state transition capability of the terminal to a controlling node; 
 receive state transition indication information and information about a target RRC state from the controlling node; and 
 transit from a current RRC state to the target RRC state according to the state transition indication information and the information about the target RRC state. 
   
     
     
         6 . The apparatus according to  claim 5 , wherein the one or more processors are further configured to:
 before the one or more processors enable the terminal to transit from the current RRC state to the target RRC state, send signaling connection release indication information carrying an information element to the controlling node, wherein the information element represents that a signaling connection release indication cause is set to the terminal requested packet switch data session end.   
     
     
         7 . The apparatus according to  claim 6 , wherein the one or more processors are further configured to receive radio link control acknowledgement information from the controlling node according to the signaling connection release indication information. 
     
     
         8 . The apparatus according to  claim 5 , wherein the one or more processors are further configured to receive reconfiguration signaling from the controlling node, and the reconfiguration signaling carries the state transition indication information and the information about the target RRC state. 
     
     
         9 . A system, comprising:
 a terminal configured to send uplink radio resource control (RRC) signaling carrying an enhanced state transition capability of the terminal;   a controlling node configured to receive the RRC signaling, generate state transition indication information according to the enhanced state transition capability of the terminal, and send the state transition indication information and information about a target RRC state to the terminal; and   wherein the terminal is further configured to transit from a current RRC state to the target RRC state according to the state transition indication information and the information about the target RRC state.   
     
     
         10 . The system according to  claim 9 , wherein the terminal is further configured to, before transiting from the current RRC state to the target RRC state, send signaling connection release indication information carrying an information element to the controlling node, wherein the information element represents that a signaling connection release indication cause is set to the terminal requested packet switch data session end. 
     
     
         11 . The system according to  claim 10 , wherein the terminal is further configured to receive radio link control acknowledgement information from the controlling node according to the signaling connection release indication information.
