Example text

11(c)) transports the IMS user data traffic. The MGW provides user data transport between the UMTS core network and the PSTN (including media conversion bearer control and payload processing). 11(j)) controls the media channels in an MGW. 11(h)) selects the network in which the PSTN (or circuit-switched domain) breakout is to occur. If the BGCF determines that a breakout is to occur in the same network, it selects an MGCF that is responsible for interworking with the PSTN. If the breakout occurs in another IMS network, the BGCF forwards the SIP request to another BGCF or an MGCF in the selected IMS network.

Precedence assignment represents an ad hoc action in that the user chooses whether or not to apply a precedence level to a call attempt. Precedence priorities include executive override, flash override, and so on. When the executive override (the highest) precedence level preempts a lower precedence call, the executive override call changes its precedence level to flash override (next highest level), so a subsequent executive override call can preempt the first precedence call. Call waiting allows a customer to answer a second call when the customer is already engaged with a call.

The origin server retrieves and returns the requested resources to the WAP gateway which is responsible for encoding the content into binary codes. Then the WAP gateway transmits the encoded content to the WAP handset through the UMTS network. The user accesses the information by a micro-browser on the WAP handset. 8(d)). Three kinds of messages are defined in WAP: • The WAP PUSH message is a specially formatted SMS message that displays an alert message allowing the user to connect to a particular Uniform Resource Locator (URL) via the mobile phone’s WAP browser.
