4.14 AT+CHLD Call related supplementary services
Description
This command allows the control the following call related services:
1. A call can be temporarily disconnected from the ME but the connection is retained by the
network.
2. Multiparty conversation (conference calls).
3. The served subscriber who has two calls (one held and the other either active or alerting)
can connect the other parties and release the served subscriber's own connection.
Calls can be put on hold, recovered, released, added to conversation, and transferred. This is
based on the GSM/UMTS supplementary services.
