Table 3.31: AG indicators for “AT+HFGI..”
7.2.9 Send Operator String to HF (“+COPS…”, #2_4.8)
AT+HFGO”<operator_string>”
Send network operator string to HF by “+COPS:0,0,”<operator_string>” on SLC.
This command shall be used to respond to a “AT+COPS?” request, indicated by the
asynchronous message HFG”OP?”.
7.2.10 Send “ERROR” or “+CME ERROR…” to HF
AT+HFGE<cme_code>
Send “ERROR” to HF if no <cme_code> is given. Required as optional response to
HFG”D>nnn” an HFG”L”.
If the optional <cme_code> is appended and if extended AG error result codes were
enabled by HF (stored internally), the appropriate extended error result code in the form
of +CME ERROR: <cme_code> is sent to HF.
If <cme_code> is appended but extended error codes have not been enabled by HF,
<cme_code> is ignored and only “ERROR” is sent to HF.
7.2.11 Subscriber Number Records (“+CNUM…”, #20_4.30)
AT+HFGS=”<number_string>”,<type>,<service>
This command adds a subscriber number record to the HFG. The subscriber number is the
telephone number of the HFG. It is allowed to have more than one subscriber numbers.
All subscriber numbers available should be stored in the HFG immediately after power up
of the system. As soon as an SLC to a HF device is established, the HF can query the HFG’s
subscriber numbers at any time by sending “AT+CNUM” to the HFG on the SLC. The
subscriber number records existing at that time will be sent to the HF automatically then.
Subscriber number records are stored in volatile memory. Hence they are lost on reset or
power cycle.
<number_string> = subscriber number string, characters allowed: 0123456789*#+ABDCTP!W@
<type> = specifies the format of <number_string> provided, can be one of the following values:
• values 128-143: The phone number format may be a national or international format,
and may contain prefix and/or escape digits. No changes on the number presentation
are required.
• values 144-159: The phone number format is an international number, including the
country code prefix. If the plus sign (“+”) is not included as part of the number and
shall be added by the AG as needed.
• values 160-175: National number. No prefix nor escape digits included.
<service> = service of this subscriber number, permitted values:
4 – voice
5 – fax
