The National Broadcasting and Telecommunications Commission (NBTC) has imposed stricter service quality standards for all Thai telecoms operators, with immediate effect, with the aim of avoiding network service disruptions, the Bangkok Post reports. The new rules, covering 50 or so existing operators, were prompted by users of cellco Digital Total Access Communication (DTAC) suffering four network outages in one month, reportedly caused by technology upgrades. Prasert Apipunya, the NBTC’s deputy secretary, said the regulator’s telecom committee approved an amendment to Article 15 of the Telecom Act extending the measures to govern operators holding licences type II and III, while passing three specific measures to regulate service quality for mobile operators. He added the NBTC asked DTAC to submit a clear plan for further 3G network upgrades, while the cellco is required to pay compensation to its customers for service disruptions. All operators must alert customers when networks go down for 30 minutes or more, while service quality must now be monitored more frequently than the previous obligatory checks every three months. Penalties for non-compliance range from warnings to fines, to licence revocation.
