Description

This command allows for reading and dynamical reporting of local emergency numbers and categories or emergency service URNs as received from the network in the Emergency Number List IE (see 3GPP TS 24.008 [8]) and the Extended Emergency Number List IE (see 3GPP TS 24.301 [83]. The emergency numbers are not necessarily received for the same <mcc> and <mnc> as currently registered to.

Read command returns one line of intermediate result code +CEN1: <reporting>,<mcc>,<mnc> with the current <reporting> setting and the Mobile Country Code <mcc> and Mobile Network Code <mnc>. Then follows zero or more occurrences of the local emergency number received in the Emergency Number List IE with intermediate result code +CEN2: <cat>,<number>. This is followed by one line of intermediate result code +CEN3: <validity> with the current <validity> setting. This is followed by zero or more occurrences of the local emergency number received in the Extended Emergency Number List IE and an associated sub-service with intermediate result code +CEN4: <number-ext>,<sub-service>.

Set command enables reporting of local emergency numbers received from the network with unsolicited result codes equal to the intermediate result codes of the read form of the command.

Test command returns values supported as a compound value.

Defined values

<reporting>: integer type. Enables and disables reporting of local emergency numbers received from the network.

0 Disable reporting

1 Enable reporting

<mcc>: integer type. A three-digit value indicating mobile country code as defined in ITU‑T Recommendation E.212 [10] Annex A.

<mnc>: integer type. A three-digit value indicating the mobile network code.

<cat>: integer type. A bitmap indicating the Emergency Service Category Value according to 3GPP TS 24.008 [8] table 10.5.135d.

<number>: String type. Representing a local emergency number from the list received in the Emergency Number List IE in 3GPP TS 24.008 [8] clause 10.5.3.13. The <number> is encoded with one digit per character and is applicable to the country indicated by <mcc>.

<validity>: integer type. Indicated validity of the local emergency number associated sub-service from the list received in the Extended Emergency Number List IE in 3GPP TS 24.301 [83] clause 9.9.3.37A.

0 Extended Local Emergency Numbers List is valid in the country of the PLMN from which this IE is received

1 Extended Local Emergency Numbers List is valid only in the PLMN from which this IE is received

<number-ext>: String type. Representing a local emergency number from the list received in the Extended Emergency Number List IE in 3GPP TS 24.301 [83] clause 9.9.3.37A. The <number-ext> is encoded with one digit per character and is applicable to the country indicated by <mcc>.

<sub-service>: String type. Representing an associated sub-service to the <number-ext>. The <sub-service> is encoded in the GSM 7 bit default alphabet and is applicable to the country indicated by <mcc> or to the PLMN indicated by the <mcc> and <mnc>. This parameter shall not be subject to conventional character conversion as per +CSCS.

Implementation

Optional.
