Problems solved by technology

[0004] From the above description, it can be seen that when the "heartbeat packet" with UDP header or TCP / IP header and MAC header is added to be transmitted through the physical layer, the physical resource overhead is large, which reduces the transmission efficiency of the wireless communication system

Embodiment 1

[0042] The embodiment of the present invention provides a heartbeat sending method, see figure 1 , the method includes: reserving uplink heartbeat physical resources and downlink heartbeat physical resources, and the specific steps include:

[0043] Step 101: the base station sends downlink heartbeat information scrambled by the RNTI (Radio Network Temporary Identifier, wireless network temporary identification number) corresponding to the user equipment to the user equipment through the downlink heartbeat physical resource;

[0044] Step 102: the user equipment receives the reserved downlink heartbeat information, and sends a heartbeat response to the base station through the corresponding uplink heartbeat physical resource.

[0045] Through the heartbeat sending method provided by the embodiment of the present invention, the heartbeat information is sent directly through the reserved physical resources without increasing the overhead of UDP header, TCP / IP header and MAC head...

Embodiment 2

[0056] The embodiment of the present invention provides a heartbeat sending method, see Figure 5 , the method includes: reserving uplink heartbeat physical resources and downlink heartbeat physical resources, and the specific steps include:

[0057] Step 501: the user equipment sends uplink heartbeat information to the base station through the corresponding uplink heartbeat physical resource;

[0058] Step 502: The base station receives the uplink heartbeat information, determines the user equipment and the RNTI corresponding to the user equipment according to the location of the time code physical resource that receives the uplink heartbeat information, and adds the RNTI to the corresponding downlink heartbeat physical resource The disturbed heartbeat response is sent to the user equipment.

[0059] Wherein, in a wireless communication system with a bandwidth of 25kHz, the reserved uplink heartbeat physical resources and downlink heartbeat physical resources include:

Abstract

The invention provides a heartbeat transmitting method and system. Uplink heartbeat physical resources and downlink heartbeat physical resources are reserved. The method comprises the following steps that: a base station transmits downlink heartbeat information scrambled via an RNTI (Radio Network Temporary Identifier) corresponding to user equipment to the user equipment through the downlink heartbeat physical resources; and the user equipment receives the downlink heartbeat information, and transmits a heartbeat response to the base station through corresponding uplink heartbeat physical resources. According to the heartbeat transmitting method and system provided by the embodiment of the invention, the heartbeat information is directly transmitted through the reserved physical resources without increasing the overhead of an UDP (User Datagram Protocol) head or a TCP (Transmission Control Protocol) / IP (Internet Protocol) head and an MAC (Media Access Control) head, so that the overhead of the physical resources can be reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for heartbeat transmission. Background technique [0002] Heartbeat detection technology is one of the key technologies for system synchronization and fault detection. It detects the status of the other party by periodically sending detection information, so as to realize working state synchronization or fault detection. In general communication systems, heartbeat detection is based on UDP and TCP / IP communication protocols, and is usually used to detect equipment connection or equipment failure. The common heartbeat detection process is: the host sends a simple communication packet to the device, process or other network elements under inspection at regular intervals. If no response is received from the other party within the specified time period, it is judged that the other party is working abnormally. The information returned by the inspected device,...
