Abstract
A system and method is disclosed for individually controlling User Equipment (UE) connections, dynamically and automatically, based on the applications and/or services that the connections carry. An eNodeB or other radio base station (RBS) monitors established connections between the UE and the RBS to detect applications running within those connections. Based on the stateful information of applications, the present invention proactively controls the state transitions of individual UEs between the CONNECTED and IDLE states thereby increasing radio link capacity and reducing control plane loading.
Claims34
A method for managing connection state transitions in a wireless communications network, the method performed at a radio base station (RBS) and comprising:
- maintaining session state information (SSI) for a user equipment (UE) communicatively connected to the RBS;
- maintaining flow information for each of one or more application flows for the UE;
- and
- transitioning the UE between a first Radio Resource Control (RRC) connection state and a second RRC connection state based on the current SSI and the flow information for an application flow, and independently of an inactivity timer.
A radio base station (RBS) in a wireless communications network, the RBS comprising:
- a communications interface configured to transmit signals to and receive signals from a plurality of user equipment (UEs);
- a controller circuit configured to:
- maintain session state information (SSI) in a memory for a UE communicatively connected to the RBS via the communications interface;
- maintain flow information in the memory for each of one or more application flows for the UE;
- and
- transition the UE between a first RRC connection state and a second RRC connection state based on the current SSI and the flow information for an application flow, and independently of an inactivity timer.
A non-transitory computer readable medium having a program stored thereon that, when executed by a controller circuit in a radio base station (RBS), causes the RBS to:
- maintain session state information (SSI) in a memory accessible to the RBS for a user equipment (UE) communicatively connected to the RBS;
- maintain flow information in the memory for each of one or more application flows for the UE;
- and
- transition the UE between a first RRC connection state and a second RRC connection state based on the current SSI and the flow information for an application flow, and independently of an inactivity timer.
A session processing module, the module comprising:
- means for maintaining session state information (SSI) for a user equipment (UE) communicatively connected to the RBS;
- means for maintaining flow information for each of one or more application flows for the UE;
- and
- means for transitioning the UE between a first RRC connection state and a second RRC connection state based on the current SSI and the flow information for an application flow, and independently of an inactivity timer.
