Abstract
Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.
