Abstract:
1. A method for transmitting keepalive information, comprising: transmitting, by a terminal, first information to a network device, wherein the first information is used to instruct the network device to determine keepalive information to be received; transmitting, by the terminal, the keepalive information to the network device, wherein the network device is configured to optimize the keepalive information by reducing signal loads between the terminal and the network device, and when the terminal has the capability of reducing the frequency of transmitting the keepalive information, obtaining, by the terminal, configuration parameters for signaling optimization preconfigured or delivered by the network device, wherein the keepalive information is duplicated and forwarded by the network device according to a timer and a counter, wherein the configuration parameters include duration of the timer, and wherein the transmitting keepalive information includes transmitting the keepalive information according to a transmission frequency indicated by the configuration parameters for signaling optimization.
