  User equipment (UE, User Equipment) may be called a mobile terminal (Mobile Terminal), a mobile user equipment, or the like. User equipment can communicate with one or more core networks through a radio access network (eg, RAN, Radio Access Network). The user equipment may be a mobile terminal, such as a mobile phone (or called a “cellular” phone) or a computer with a mobile terminal. For example, the user equipment can be a portable, pocket-sized, handheld, computer embedded, or in-vehicle mobile device that exchanges language and / or data with a radio access network.

The type of base station is not limited in the present invention. However, for ease of explanation, eNB is used as an example in the following embodiments for explanation.

  FIG. 1 is a flowchart of an information transmission method according to an embodiment of the present invention. The method of FIG. 1 is performed by a base station.

  101. Generate a paging message after the earthquake and tsunami warning system ETWS message has been broadcast.

  102. Send a paging message to the UE that is in the state of monitoring the ETWS message, and the paging message is used to instruct the UE to receive the system information block, which contains the ETWS primary notification PN and ETWS secondary Does not carry scheduling mapping information of notification SN.

  In this embodiment of the invention, the UE receives the paging message broadcast by the base station and actively receives the system information block that does not carry the scheduling mapping information of the ETWS primary notification PN and ETWS secondary notification SN, and thus The UE may stop monitoring ETWS messages, thereby effectively reducing UE power consumption.

  Alternatively, as one embodiment, the paging message may be a paging message that carries an instruction message to update the system message. It should be understood that this is not limited in this embodiment of the invention. A paging message that can trigger the UE to actively receive system information blocks that do not carry ETWS PN and ETWS SN scheduling mapping information when the UE does not leave the serving cell is a feature of this embodiment of the invention. Within range.

  Alternatively, as another embodiment, the System Info Value tag field of the system information block remains unchanged before the base station sends the paging message and after the base station sends the paging message. possible. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN.

  Specifically, after completing the broadcast of the ETWS message, the base station broadcasts a paging message carrying a system message update indication message. After receiving the paging message, the UE actively receives SIB1, and SIB1 does not carry the scheduling mapping information of ETWS PN and ETWS SN, and the System Info Value tag field of SIB1 remains unchanged. Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages and is no longer in a power consumption state, thereby saving power consumption.

  In the following, in combination with the example of FIG. 2, a non-limiting implementation manner of the information transmission method will be described in detail.

  FIG. 2 is a flowchart of an information transmission method according to an embodiment of the present invention. The method of FIG. 2 is executed by the user equipment and corresponds to the method of FIG. Accordingly, repeated description in the embodiment of FIG. 1 is appropriately omitted.

  201. When the user equipment is in a state of monitoring ETWS messages, it receives a paging message broadcast by the base station.

  202. A system information block is received according to the paging message, and the system information block does not carry scheduling mapping information of the ETWS primary notification PN and the ETWS secondary notification SN.

  203. Stop monitoring ETWS messages according to the system information block.

  In this embodiment of the invention, the UE receives the paging message broadcast by the base station and actively receives the system information block that does not carry the scheduling mapping information of the ETWS primary notification PN and ETWS secondary notification SN, and thus The UE may stop monitoring ETWS messages, thereby effectively reducing UE power consumption.

  Alternatively, as one embodiment, the paging message may be a paging message that carries an instruction message to update the system message. It should be understood that this is not limited in this embodiment of the invention. A paging message that can trigger the UE to actively receive system information blocks that do not carry ETWS PN and ETWS SN scheduling mapping information when the UE does not leave the serving cell is a feature of this embodiment of the invention. Within range.

  Alternatively, as another embodiment, the System Info Value tag field of the system information block remains unchanged before the base station sends the paging message and after the base station sends the paging message. possible. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN.

  Specifically, the base station has completed broadcasting the ETWS message, but the UE is still in a state to monitor the ETWS message. For example, the UE's downlink received signal suddenly weakens so that the ETWS message cannot be completely received. In this case, the UE is always in a state of monitoring the ETWS message, and does not actively receive SIB1 that does not carry scheduling mapping information of the ETWS PN and ETWS SN. After receiving a paging message actively delivered by the base station (e.g., a paging message carrying an instruction message to update the system message), the UE actively receives the system information block, and the system information block Does not carry scheduling mapping information for PN and ETWS SN. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN. Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages and is no longer in a power consumption state, thereby saving power consumption.

  In the following, an embodiment of the present invention will be described in combination with a specific example.

  FIG. 3 is a schematic flowchart of a process of an information transmission method according to an embodiment of the present invention.

  In FIG. 3, eNB is used as an example of a base station for explanation. It should be understood that this is not limited in this embodiment of the invention. The number of ETWS SN fragments in FIG. 3 is only an example, and this does not limit this embodiment of the invention, and the ETWS SN may not be fragmented or more Note that ETWS SN fragments may be present. It should also be understood that the number of broadcasts and the broadcast interval for ETWS PN or ETWS SN are not limited in this embodiment of the invention.

  301. MME sends Write-Replace Warning Request to eNB.

  302. The base station returns a write replacement warning response Write-Replace Warning Response to the MME.

  303. The eNB broadcasts an ETWS message to the UE.

  Broadcast content includes ETWS PN and ETWS SN. The ETWS PN is used to quickly notify the user of the most urgent information about an imminent event (eg, imminent earthquake or tsunami). The ETWS SN is primarily used to send additional information (eg, what to do or where to get help when an emergency occurs). In general, ETWS PNs do not need to be fragmented and are broadcast continuously at regular intervals. However, when there are multiple ETWS SNs, fragmented broadcasts are required. For example, the ETWS SN is divided into two fragments: SN fragment 1 and SN fragment 2. The ETWS SN is broadcast according to the broadcast count and broadcast interval configured on the MME. For example, for ETWS SN, the broadcast count is configured as 2 and the broadcast interval is configured as 10 seconds.

  The UE receives the paging message paging (with etws-ind) sent by the eNB, which carries the ETWS message indication, and therefore receives the SIB1 (mapping information SIB10 SIB11), and the fixed time according to the relation information given by the SIB1. On the frequency location, SIB10 (PN) carrying ETWS PN and SIB11 (SN) carrying ETWS SN are monitored.

  The eNB has completed the broadcast of the ETWS message, but the UE is still in a state to monitor the ETWS message. For example, the UE's downlink received signal suddenly weakens so that the ETWS message cannot be completely received. Further, the UE does not actively receive SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN. In another example, the eNB broadcasts the ETWS SN last when the UE is powered on. As a result, the UE does not receive the ETWS SN completely and does not actively receive the SIB1 that does not carry the ETWS PN and the scheduling mapping information of the ETWS SN. Therefore, the UE is always in a state of monitoring SIB11, that is, the UE is always in a power consumption state.

  304. The eNB sends a paging message carrying the instruction message to update the system message to the UE.

  305. The eNB sends SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN to the UE.

  After receiving a paging message actively delivered by an eNB (e.g., a paging message carrying an instruction message to update a system message), the UE does not carry scheduling mapping information for ETWS PN and ETWS SN Actively receive. Alternatively, the system information value tag System Info Value tag field of the system information block may remain unchanged before the eNB sends the paging message and after the eNB sends the paging message. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN. That is, the system information block is SIB1 sent by the eNB to the UE when the broadcast is completed, where the SIB10 and SIB11 scheduling mapping information is deleted and the System Info Value tag field of SIB1 remains unchanged. . Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages, thereby saving power consumption.

The type of base station is not limited in the present invention. However, for ease of explanation, eNB is used as an example in the following embodiments for explanation.

Specifically, after completing the broadcast of the ETWS message, the base station broadcasts a paging message carrying a system message update indication message. After receiving the paging message, the UE actively receives SIB1, and SIB1 does not carry the scheduling mapping information of ETWS PN and ETWS SN, and the System Info Value tag field of SIB1 remains unchanged. Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages and is no longer in a power consumption state, thereby reducing power consumption.

Specifically, the base station has completed broadcasting the ETWS message, but the UE is still in a state to monitor the ETWS message. For example, the UE's downlink received signal suddenly weakens so that the ETWS message cannot be completely received. In this case, the UE is always in a state of monitoring the ETWS message, and does not actively receive SIB1 that does not carry scheduling mapping information of the ETWS PN and ETWS SN. After receiving a paging message actively delivered by the base station (e.g., a paging message carrying an instruction message to update the system message), the UE actively receives the system information block, and the system information block Does not carry scheduling mapping information for PN and ETWS SN. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN. Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages and is no longer in a power consumption state, thereby reducing power consumption.

Broadcast content includes ETWS PN and ETWS SN. The ETWS PN is used to quickly notify the user equipment of the most urgent information about an imminent event (eg imminent earthquake or tsunami). The ETWS SN is primarily used to send additional information (eg, what to do or where to get help when an emergency occurs). In general, ETWS PNs do not need to be fragmented and are broadcast continuously at regular intervals. However, when there are multiple ETWS SNs, fragmented broadcasts are required. For example, the ETWS SN is divided into two fragments: SN fragment 1 and SN fragment 2. The ETWS SN is broadcast according to the broadcast count and broadcast interval configured on the MME. For example, for ETWS SN, the broadcast count is configured as 2 and the broadcast interval is configured as 10 seconds.

After receiving a paging message actively delivered by an eNB (e.g., a paging message carrying an instruction message to update a system message), the UE does not carry scheduling mapping information for ETWS PN and ETWS SN Actively receive. Alternatively, the system information value tag System Info Value tag field of the system information block may remain unchanged before the eNB sends the paging message and after the eNB sends the paging message. Further, the system information block may be SIB1 that does not carry scheduling mapping information of ETWS PN and ETWS SN. That is, the system information block is SIB1 sent by the eNB to the UE when the broadcast is completed, where the SIB10 and SIB11 scheduling mapping information is deleted and the System Info Value tag field of SIB1 remains unchanged. . Thus, the UE does not update the system message after receiving a paging message that carries an instruction message to update the system message. As a result, the UE stops monitoring ETWS messages, thereby reducing power consumption.
