Method and system for paging an emergency service user

摘要

The present disclosure discloses a method for paging an emergency service user. When a mobility management unit is configured to support the paging optimization in a core network, the mobility management unit does not perform paging optimization when a UE has an emergency bearer service. That is to say, a paging message is sent to all base stations (including the CSG-mode home base station that does not authorize the UE) in the paging tracking list registered by the UE. A core network gateway can notify the mobility management unit of whether the UE has an emergency bearer service. Alternatively, the mobility management unit configured to use the paging optimization, after learning that the service data is to be sent to the UE, checks the current service type of the UE to determine whether the UE has an emergency bearer service. Accordingly, the present disclosure further discloses a system for paging an emergency service user. The present disclosure solves the problem that the mobility management unit and home base station gateway using the paging optimization cannot page the UE which uses the emergency service, so as to increase the success rate of establishing communications and improve the user experience.

1. A method for paging an emergency service user, comprising:
when a mobility management unit is configured to support paging optimization in a core network, not performing the paging optimization by the mobility management unit when a UE has an emergency bearer service; wherein the step of that the mobility management unit configured to use the paging optimization does not perform the paging optimization when the UE has an emergency bearer service comprises: after receiving a downlink data packet to be sent to the UE, a core network gateway notifies the mobility management unit that service data included in the downlink data packet is emergency service data when the service data included in the downlink data packet is the emergency service data; after learning that the emergency data is to be sent to the UE, the mobility management unit configured to use the paging optimization sends a paging message to all base stations, including a CSG-mode (Closed Subscriber Group mode) home base station that does not authorize the UE, in a paging tracking list registered by the UE; and the CSG-mode home base station pages the UE.
