Abstract
A method and a system for idle mode signaling reduction (ISR) are provided. The method includes: obtaining ISR activation information of a source network, and setting an ISR status of an user equipment (UE) in a target network according to the obtained ISR activation information of the source network. Thus, the ISR status of the UE can be processed when the UE is handed over between networks.
Claims29
A method for idle mode signaling reduction (ISR), comprising:
- obtaining ISR activation information of a source network;
- and
- setting an ISR status of a user equipment (UE) in a target network according to the obtained ISR activation information of the source network.
A method for idle mode signaling reduction (ISR), comprising:
- if a mobility management network element of a target network has an ISR capability, determining whether to activate an ISR of a user equipment (UE) in the target network according to an ISR capability or an ISR activation status of a source network, and if the source network supports the ISR or has activated the ISR, activating the ISR of the UE in the target network.
A system for idle mode signaling reduction (ISR), comprising:
- a mobility management network element of a target network, configured to obtain ISR activation information of a source network, and set an ISR status of a user equipment (UE) in the target network according to the obtained ISR activation information of the source network;
- and
- a serving gateway (SGW) of the target network, configured to record the ISR status of the UE in the target network set by the mobility management network element of the target network.
A mobility management network element, comprising:
- an obtaining unit, configured to obtain idle mode signaling reduction (ISR) activation information of a source network;
- and
- a setting unit, configured to set an ISR status of a user equipment (UE) in a target network according to the ISR activation information of the source network obtained by the obtaining unit.
A mobility management network element, comprising:
- a determining unit, configured to determine whether to activate an idle mode signaling reduction (ISR) of a user equipment (UE) in a target network according to an ISR capability or an ISR activation status of a source network when a mobility management network element of the target network has an ISR capability;
- and
- an activating unit, configured to activate the ISR of the UE in the target network when the determining unit determines that the source network has the ISR capability or has activated the ISR.
