Problems solved by technology

[0005] At present, the MME still has the following problems when routing the alarm request sent to the base station: when the base station is a HeNB and the HeNB accesses the core network through the HeNB GW, the MME only knows the identity of the HeNB but not the identity of the HeNB GW. When specifying the alarm request sent to the HeNB, the MME cannot index to the HeNB or the HeNB GW accessed by the HeNB according to the identity of the HeNB

Embodiment Construction

[0054] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0055] figure 2 It is a schematic flowchart of a method for supporting PWS fast recovery in the present invention.

[0056] In step 201, the HeNB sends a restart instruction to the HeNB GW, and the instruction includes the identity of the HeNBGW it accesses or the identity of the TA supported by the HeNB.

[0057] The restart instruction includes an eNB ID, and when the HeNB accesses the MME through the HeNB GW, the HeNB sets the eNB ID as the ID of the HeNB GW accessed by the HeNB.

[0058] In step 202, the HeNB GW sends a restart instruction from the HeNB to the MME.

[0059] In step 203, the MME sends the received restart instruction to the CBC.

[0060] Step 204, after the CBC receives the restart instruction, the CBC decides to restore the alarm informa...

Abstract

The present invention provides a method for supporting the rapid recovery of the public warning service PWS. The MME receives the restart instruction of the HeNB sent by the HeNB GW; the MME sends the restart instruction of the HeNB to the CBC, including the index information of the HeNB and / or the index information of the HeNB GW ; The MME receives the alarm request sent by the CBC, including the index information of the HeNB and / or the index information of the HeNB GW; the MME sends the alarm request to be sent to the HeNB to the HeNB GW.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for supporting PWS fast recovery. Background technique [0002] The Public Warning System is mainly used to support the notification of forecast events such as earthquakes and hurricanes to the public as warning information. The public early warning system is realized by sending the warning message, warning area, sending request, etc. to the base station, and the base station performs scheduling and broadcasting in the designated warning area. [0003] The schematic diagram of the public early warning system architecture is as follows: figure 1 shown in figure 1 Among them, 101 base station schedules and broadcasts alarm information from CBC, and the alarm information is forwarded by CBC to the base station through MME; 102 home base station can directly access the core network or access through 103 home base station gateway. For the latter, MME forwards the alarm i...
