A partner endpoint refers to the partner-owned and partner-operated
infrastructure that receives user emergency location information from ELS. ELS
supports these protocols for reporting location information and additional
emergency information to endpoints:
Types of endpoint
ELS supports these protocols for reporting location information and additional
emergency information to endpoints:
HTTPS: The partner endpoint is a standard HTTPS server capable of
receiving POST requests. ELS information is encoded as name-value pairs in each
POST request. See ELS HTTPS Specification.
SMS: The partner endpoint is a phone number (short code or long code)
capable of receiving SMS messages. SMS messages can be sent as regular SMS
or Data SMS. See ELS SMS Specification.
Both of the transmission protocols comply with the ETSI
AML standard, but can be extended by adding additional
fields and capabilities, as described in this documentation.
Why use both
Each of the transmission protocols described earlier has advantages and
disadvantages. Android strongly recommends using both protocols simultaneously,
with basic matching on phone number or IMEI, to gain the benefits of both. For
more on the ideal way to combine both formats, see EENA
webinar.
Security considerations
Regardless of the endpoint type, consider security. Endpoints must be resilient
to distributed denial-of-service (DDoS) and other kinds of attacks, and may be
required to undergo a Google security audit prior to deployment.
Compliance
Android's implementation of AML should comply with the latest published ETSI
AML standard and with the relevant regulation (such as,
Delegated Regulation (EU) 2019/320). For any questions
or concerns about compliance testing, contact your test lab. Google can only
support specific questions about testing and compliance directly from certified
testing laboratories.
