Abstract

The invention discloses an activity-keeping detecting method connected with a radio resource control layer, which includes the following steps: determining a terminal that the existence time of the radio resource at the network side meets the preset requirement; sending activity-keeping detecting information to the terminal, and determining the terminal in an unactivated state when activity-keeping response information is not received from the terminal in the preset time. In addition, the invention also discloses an activity-keeping detecting system connected with the radio resource control layer and a device thereof. The technical proposal of the invention can reduce the risk that related resource at the network side is hanged.

Description

technical field

[0001] The present invention relates to communication technology, in particular to a method, system and device for keeping alive detection of a radio resource control layer (RRC) connection. Background technique

[0002] In the communication system, the network side communicates with the terminal through a Uu interface (also called a wireless interface). Uu interface is divided into 3 layers: physical layer (L1), data link layer (L2) and network layer (L3). Among them, the data link layer is divided into four sublayers: media access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), broadcast / multicast control (BMC); the network layer is divided into There are three sublayers: Radio Resource Control (RRC), Mobility Management (MM) and Connection Management (CM), where only the RRC sublayer exists on the access network side that communicates with the terminal.

[0003] When the RRC connection is established, the network side al...
