Abstract
A downlink emergency service transmission method and a system, where the method includes reserving, by a base station from system resource, resource as reserved resource for transmitting a downlink emergency service, sending, by the base station, first indication information to user equipment, so as to instruct the user equipment to receive a downlink emergency service by using a resource indicated by the first indication information, where the first indication information is used to indicate the reserved resource, and sending, by the base station, the downlink emergency service to the user equipment by using the reserved resource.
Claims17
A downlink emergency service transmission method, comprising:
- receiving, by a user equipment in a first transmission time interval (TTI), first indication information sent by a base station, wherein the first indication information indicates a reserved resource, and wherein the reserved resource is a first resource that is reserved by the base station from a system resource and that is used to transmit a downlink emergency service;
- and
- receiving, by the user equipment, in the first TTI, according to the first indication information and using the first resource indicated by the first indication information, a downlink emergency service sent by the base station.
A base station, comprising:
- a processor;
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to reserve, from a system resource, a first resource as a reserved resource for transmitting a downlink emergency service;
- and
- a transmitter, configured to transmit, to a user equipment in a first transmission time interval (TTI), first indication information instructing the user equipment to receive a downlink emergency service using the first resource indicated by the first indication information, wherein the first indication information indicates the reserved resource, wherein the transmitter is further configure to transmit the downlink emergency service in the first TTI to the user equipment using the reserved resource.
User equipment, comprising:
- a receiver, configured to receive first indication information sent by a base station in a first transmission time interval (TTI), wherein the first indication information indicates a reserved resource, wherein the reserved resource is a first resource that is reserved by the base station from system resource and is used to transmit a downlink emergency service, and wherein then receiver is further configured to receive, according to the first indication information, in the first TTI, and using the first resource indicated by the first indication information, a downlink emergency service sent by the base station.
