Abstract
A service recovery method and a device for a wireless communication network are disclosed. In an embodiment, the method includes receiving, by a target base station, a radio resource control (RRC) re-establishment request from a terminal and sending, by the target base station, an indication message indicating a radio link failure to a source base station to trigger the source base station with self-determination to initiate a handover preparation procedure between the source base station and the target base station, wherein the terminal remains in an active state.
Claims14
A service recovery method comprising:
- receiving, by a target base station, a radio resource control (RRC) re-establishment request from a terminal;
- and
- sending, by the target base station, an indication message, in response of the RRC reestablishment request, indicating a radio link failure to a source base station to trigger the source base station with self-determination to initiate a handover preparation procedure between the source base station and the target base station, wherein the terminal remains in an active state.
An apparatus comprising:
- a receiver configured to receive a radio resource control (RRC) re-establishment request from a terminal;
- and
- a transmitter configured to send an indication message, in response to a RRC re-establishment request, indicating a radio link failure to a source base station to trigger the source base station with self-determination to initiate a handover preparation procedure between the source base station and a target base station wherein the terminal remains in an active state.
A service recovery method comprising:
- receiving, by a source base station, an indication message indicating a radio link failure sent from a target base station;
- and
- initiating with self-determination, by the source base station, a handover preparation procedure between the source base station and the target base station triggered by the indication message.
An apparatus comprising:
- a receiver configured to receive an indication message indicating a radio link failure sent from a target base station;
- and
- a processor configured to initiate with self-determination a handover preparation procedure between the apparatus and the target base station triggered by the indication message.
