Emergency Alerting in England – Warning simulation exercise (Cell Broadcast Trials 2019)

Tutorial de como receber mensagens de Cell Broadcast / Difusão Celular no computador


Com os passos que irão ser indicados neste tutorial será possível de uma forma prática receber todo o tipo de informações e canais que estejam a ser emitidos por Cell Broadcast / Difusão Celular por parte de uma operador móvel numa determinada BTS.

Será necessário ter uma placa de Banda Larga da marca Huawei. Como por exemplo a que apresento na fotografia:

Deverá descarregar os ficheiros alojados em https://oh6tjl.s.cld.pt/ e descompactar os mesmos para uma pasta.

A fonte do software Monitorsoftware é em http://www.nobbi.com/download.html caso queira obter mais informações sobre o programador ou sobre o software.

Deverá ter um cartão SIM inserido na PEN de Banda Larga com o PIN desactivado.

Na experiência que realizei para este tutorial utilizei um cartão SIM da operadora móvel altice MEO | altice Portugal pelo facto de emitirem Cell Broadcast / Difusão Celular em Portugal. Pode ser utilizado um cartão SIM MEO / UZO / MOCHE ou NOWO.

Ligar a PEN de Banda Larga no PC, o software da placa de banda larga móvel não pode ficar aberto caso ele abra automaticamente, deverá ser fechado.
No computador / tablet clicar no ícone do software mdma para abrir o programa.
Na opção connection type escolher só GPRS / EDGE.
Se houver emissões de Cell Broadcast, as mesmas irão aparecer na janela referente às mensagens de Cell Broadcast.
De seguida deverá escolher Device Info para saber a que porta ficou atribuído o MODEM.
No programa mdma dá para se ver as emissões de Cell Broadcast que se vai recebendo, mas a informação não é tão detalhada como o próximo programa. Para o Monitorsoftware funcionar sem ser necessário um telemóvel ou modem Siemens é necessário correr primeiro o mdma.
Os ficheiros descompactados do Monitor são os seguintes:
Deverá clicar no ficheiro MConfig, ao abrir o programa Configure your TAPIR deverá escolher a porta que aparecia no software mdma atribuída ao MODEM.
No separador “Options I” deverá seleccionar tudo como está na imagem:
Deverá clicar em Save e de seguida em Exit.
Fechar o software mdma e abrir o software Monitor
Seleccionar todos os campos. Debugmode, Activate Timer, Show Data e Simulation.
No simulate escolher a opção Startup Siemens S55 como está na imagem.
Deverá clicar na seta do lado direito e depois em Parse.
Irá começar a aparecer a informação na janela de lado com a informação do Cell Id da Rede e LAC. Deverá colocar o visto no campo Show SMSCB para começar as receber as mensagens de Cell Broadcast / Difusão Celular.
Mesmo aparecendo mensagens de erro, o programa começa a receber qualquer canal e informação que esteja a ser emitido no Cell Broadcast / Difusão Celular.
Os logs das informações recolhidas ficam guardados na pasta do programa no formato txt.

Octecto 1 e 2 HEX 0000 em Binário 0000000000000000 em que os primeiros dois bits representam o Geoscope = 0 (00) (Cell-Wide) que apresenta a mensagem directamente no display do equipamento e é válida apenas na célula em que é recebida, o equipamento irá ignorar mensagens repetidas na mesma célula. Os bits (0000000000) representam o código da mensagem e os (0000) restantes a actualização do número.

Octecto 3 e 4 HEX 0032 em binário 0000000000110010 indica o canal 50 em decimal.

Octecto 5 HEX 01 (Data Coding Scheme) indica que o idioma é em Inglês.

Octecto 6 HEX 11 é o parâmetro da página que em binário é 00010001 que significa página 1 de 1.
