Embodiment 4

[0066] Embodiment 4 of the present invention provides a mobility management entity MME, the MME includes:

[0067] a receiving unit, configured to receive an ETWS message;

[0068] A setting unit, configured to set an information change flag when the received ETWS message is different from the ETWS message stored by the MME itself;

[0069] A sending unit, configured to send the ETWS message received by the receiving unit and the information change flag set by the setting unit.

[0070] The MME may also include a saving unit, configured to save the received ETWS message and / or the information change identifier.

[0071] Embodiment 5 of the present invention provides a user equipment UE, where the UE includes:

[0072] The execution unit is configured to read the area identifier carried in the system message of the adjacent cell B to which the handover or reselection is performed, and the area identifier is used to indicate the area to which the cell belongs;

[0073] A read...

Abstract

The embodiment of the invention provides message sending and receiving methods, equipment and systems. The message sending method comprises the following steps: a mobility management entity (MME) receives an earthquake and tsunami warning system (ETWS) message; when the received ETWS message is different from an ETWS message stored in the MME, the MME sets an information change identifier; and the MME sends the received ETWS message and the information change identifier. In the embodiment of the invention, sending of the ETWS message to an eNB (evolved Node B) is decided by using the MME, so that the eNB is only required to transmit the received message to UE (User Equipment) without judging the contents of the ETWS message, the signaling flow complexity of the transmission of the ETWS message with the eNB is lowered, and the load of access network equipment is lightened.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a message sending and receiving method, device and system. Background technique [0002] Long Term Evolution (LTE) is a next-generation mobile broadband network standard formulated by the 3rd Generation Partnership Project (3GPP) standardization organization. It has high spectrum utilization and transmission speed, and low The advantages of transmission delay and so on. [0003] By carrying the earthquake and tsunami warning system (Earthquake and Tsunami Warning System, ETWS) message in the LTE system message sent to the user equipment (User Equipment, UE), the LTE system can promptly notify the user of the tsunami warning indication when an earthquake or tsunami occurs, Post-disaster rescue and other relevant information. [0004] ETWS messages are classified into Primary Notification (PN) and Secondary Notification (SN). The PN carries less content, which is mainly...
