Problems solved by technology

For the scenario of directly reading system messages, the network side may not modify the system messages for a long period of time, and MTC terminals frequently read unmodified system messages, which has a problem of high power consumption.

Embodiment Construction

[0030] In the prior art, the existing method for reading system information under the LTE standard is designed for non-MTC terminals. When applied to MTC terminals, there will be two problems:

[0031] 1) When reading the system message by judging whether the value flag of the system message has changed, the MTC terminal may mistakenly believe that the system message has not changed. Due to the requirement of low power consumption of the MTC terminal, the MTC terminal stays in the normal parking state for a certain period of time after it is turned on, and the MTC terminal does not listen to the paging message when it is in the deep sleep state. At present, the value mark of the system message has only 32 values, which are 0 to 31 in turn. When the system message changes 32 times, the value mark of the system message will cycle to the original value. For example, if the value of the system message is marked as 0, after the system message changes 32 times, the value of the sys...

Abstract

The invention relates to a method and a device for communicating with an MTC (Machine Type Communication) terminal and a base station. The method comprises the steps of monitoring whether a system message for the MTC terminal changes or not in real time; enabling a count value of a preset N-level counter to plus 1 when the system message is detected to change, wherein the counting method of the N-level counter comprises the steps of adopting an ith-level counter to count when a count value of a (i-1)th-level counter is the maximum; enabling an accumulated value of the current N-level counter to act as a system message value marker; and sending the system message value marker to the MTC terminal, enabling the MTC terminal to compare the system message value marker with a currently stored system message value marker after acquiring the system message value marker, and judging the system message to be not changed when the two markers are identical. By adopting the method, the device and the base station, a circumstance that the MTC terminal mistakenly judges that the system message is not changed can be avoided, and the power consumption, which is caused by frequently reading unmodified system messages, of the MTC terminal is reduced.

Description

technical field [0001] The present invention relates to the field of MTC communication, in particular to a method, device and base station for communicating with an MTC terminal. Background technique [0002] In the existing protocol, a user terminal (User Equipment, UE) that supports the LTE standard is faced with various application scenarios for reading system information, for example, every time the UE is turned on, the UE re-accesses the current serving cell after leaving the current serving cell, and the UE Switch from connected state to idle state etc. [0003] In some scenarios, for example, after the UE leaves the current serving cell and re-accesses the current serving cell, the UE receives a paging message indicating that the system information has changed, first reads the system information block 1 (System Information Block 1, SIB1), and determines whether the SIB1 Whether the system information value tag (systemInfoValueTag) of the UE is consistent with the sys...
