Abstract

Provided are methods and devices for reporting a broadcast state of a warning message. In the method, an evolved Node B (eNB) receives a state request message from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message; in response to the state request message, the eNB reports the broadcast state of the warning message to the MME. By means of the technical solution, the effect that a network side can report a broadcast state of a warning message according to a state request from a Cell Broadcast Center (CBC) is achieved.

First claim

What is claimed is:

1. A method for reporting a broadcast state of a warning message, comprising:
receiving, by an evolved Node B (eNB), a state request message, or a indication information, or a state request message and a indication information, from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message, the indication information is used for indicating the eNB to report a broadcast state of a warning message;
in response to the state request message, or the indication information, or the state request message and the indication information, reporting, by the eNB, the broadcast state of the warning message to the MME;
wherein the state request message contains one of the following: a reporting attribute of the warning message, a reporting period of the warning message, and the reporting attribute of the warning message as well as the reporting period of the warning message;
wherein the broadcast state of the warning message comprises: broadcast state of whole warning messages, or broadcast state of designated warning messages;
wherein when the state request message contains the reporting attribute of the warning message, reporting, by the eNB, the broadcast state of the warning message to the MME comprises: sending, by the eNB, the broadcast state of the warning message to the MME through a state response message, wherein in a case that an attribute content of the reporting attribute of the warning message contained in the state request message is not null, the broadcast state of the warning message is the broadcast state of the whole message of the attribute content; and in a case that the attribute content of the reporting attribute of the warning message contained in the state request message is null, the broadcast state of the warning message is the broadcast state of all warning messages, or the broadcast state of the warning message is the broadcast state of designated warning messages.

2. The method according to claim 1 , wherein the broadcast state of each warning message in all the warning messages comprises: an attribute of each warning message being reported in a current moment, or an attribute of each warning message that has been broadcast within a preset time interval before the current moment, or an attribute of each warning message being reported in a current moment and an attribute of each warning message that has been broadcast within a preset time interval before the current moment;
the broadcast state of each warning message in the one or more predetermined warning messages is a broadcast state of each warning message in one or more designated warning messages that need to be reported.

3. The method according to claim 1 , wherein when the state request message contains the reporting period of the warning message, reporting, by the eNB, the broadcast state of the warning message to the MME comprises:
sending, by the eNB, one or more preset broadcast states of the warning message to the MME through a state response message according to the reporting period of the warning message contained in the state request message.

4. The method according to claim 1 , wherein when the state request message contains the reporting attribute of the warning message as well as the reporting period of the warning message, reporting, by the eNB, the broadcast state of the warning message to the MME comprises:
sending, by the eNB, the broadcast state of the warning message to the MME through a state response message according to the reporting period of the warning message contained in the state request message, wherein in a case that an attribute content of the reporting attribute of the warning message contained in the state request message is not null, the broadcast state of the warning message is the broadcast state of the warning message corresponding to the attribute content; and in a case that the attribute content of the reporting attribute of the warning message contained in the state request message is null, the broadcast state of the warning message is all broadcast states or one or more preset broadcast states of the warning message.

5. The method according to claim 1 , wherein when an attribute content of the reporting attribute of the warning message contained in the state request message is not null, the attribute content comprises at least one of the followings:
a Message Identifier Information Element (IE) for identifying the warning message and a Serial Number IE of the warning message;
a Broadcast Completed Area List IE for indicating areas in which the warning message is broadcast successfully;
a Repetition Period IE for indicating a broadcast period of the warning message; and
a Number of Broadcast Requested IE for indicating the number of broadcasting times of the warning message.

6. The method according to claim 1 , wherein the state request message is sent by a Cell Broadcast Center (CBC) to the MME.

7. The method according to claim 6 , wherein in a case that the eNB fails in processing the state request message, the eNB returns a state response failure message to the MME, wherein the state response failure message comprises: a failure cause, or a waiting time, or a failure cause and a waiting time.

8. A device for reporting a broadcast state of a warning message, wherein the device is located in an evolved Node B (eNB) and the device comprises a hardware processor configured to execute program components stored on a memory, wherein the program components comprise:
a first receiving component, connected with a processing component, configured to receive a state request message from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message;
the processing component, connected with the first receiving component and configured to, in response to the state request message, report the broadcast state of the warning message to the MME;
or,
the device is located in an eNB and the device comprises a hardware processor configured to execute program components stored on a memory, wherein the program components comprise:
a second receiving component, connected with a reporting component and configured to receive indication information from a Mobile Management Entity (MME), wherein the indication information is used for indicating the eNB to report a broadcast state of a warning message;
the reporting component, connected with the second receiving component and configured to, in response to the indication information, report the broadcast state of the warning message to the MME;
or,
the device is located in an eNB and the device comprises a hardware processor configured to execute program components stored on a memory, wherein the program components comprise:
the first receiving component, connected with the processing component, configured to receive a state request message from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message;
the processing component, connected with the first receiving component, in response to the state request message, report the broadcast state of the warning message to the MME;
the second receiving component, connected with the reporting component configured to receive indication information from a Mobile Management Entity (MME), wherein the indication information is used for indicating the eNB to report a broadcast state of a warning message;
the reporting component, connected with the second receiving component, configured to, in response to the indication information, report the broadcast state of the warning message to the MME;
wherein the state re
