+CSNS, Single Numbering Call Scheme

This command handles the selection of the bearer or teleservice to be used when a mobile terminated single numbering scheme call is established. If the calling party specifies the required bearer capability, this capability is used for the call setup attempt. If the calling party does not specify the required bearer capability (for example, because the call originated in the PSTN), the network attempts to determine it, as described below.

Some cellular networks use a multi-numbering scheme, where several mobile station ISDN numbers, or MSISDNs, are associated with one IMSI in order to define the bearer capability by the MSISDN. Each MSISDN is used for a different bearer capability. If the network uses a multi-numbering scheme and the calling party has not specified the required bearer capability, then the network uses the bearer capability associated with the called party MSISDN.

However, some networks omit the bearer capability associated with the called party MSISDN, when this MSISDN is associated with voice service and the calling party has not specified the required bearer capability (for example, because the call originated in the PSTN). In these cases, the +CSNS command is used to select the desired bearer or teleservice for a single-numbering scheme, in which one MSISDN is associated with each IMSI. The +CSNS command has a default mode, so is not mandatory to set it.

If the network uses a single-numbering scheme and the calling party has not specified the required service, then the network omits the bearer capability information.
