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> = species 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,
