Embodiment Construction

[0057] The terms used in the embodiments of the present invention are only used to explain specific examples of the present invention, and are not intended to limit the present invention. The technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention.

[0058] see figure 1 , figure 1 The communication system involved in the embodiment of the present invention is shown, in which the base station and the UE communicate with each other through some air interface technology. The air interface technology may include: the existing 2G (such as GSM), 3G (such as UMTS, WCDMA, TD-SCDMA), 4G (such as FDD LTE, TDD LTE), and the 4.5G and 5G systems that will be launched in the future. The base station may include: an eNB in ​​an LTE communication system, a NodeB in a UMTS communication system, and a BS (Base Station) in a GSM communication system. UE is the user terminal in th...

Abstract

The embodiment of the invention discloses a downlink emergency service transmission method and system. The method includes: the base station reserves reserved resources for transmitting downlink emergency services from system resources; the base station sends first indication information to the user equipment to indicate the user equipment indicated by the first indication information The resource receives the downlink emergency service; the first indication information is used to indicate the reserved resource; the base station sends the downlink emergency service to the user equipment through the reserved resource. The scheme of the invention can improve the transmission efficiency of the downlink emergency service and ensure the timely transmission of the downlink emergency service.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a downlink emergency service transmission method, base station, user equipment and system. Background technique [0002] Emergency service transmission, such as the transmission of certain alarm information in industrial control, is an application scenario for future 4.5G and 5G communication systems. The amount of data to be transmitted each time for emergency services is small, but must be transmitted quickly. Short transmission delay is an important feature of emergency services. [0003] In the prior art, when a base station sends a non-emergency service to a user equipment (User Equipment, UE), that is, a traditional data service in an existing communication system, such as a Mobile Broadband (MBB) service, due to the system resources of the current TTI Already allocated and occupied, the base station generally needs to wait for the next transmission tim...
