Abstract: A device determines whether a PTT application is authenticated to access a first API and a second API, and prevents the PTT application from accessing the first and second APIs when the PTT application is not authenticated. The device permits the PTT application to access the first and second APIs when the PTT application is authenticated, and modifies, via the first API, a timer that dictates when the device checks for traffic received from a network. The device establishes, via the second API, a data connection with the network, and determines, based on the data connection, a QoS framework for the network. The device utilizes the PTT application and the timer to establish a PTT session with another device via the network, and prioritizes, based on the QoS framework, PTT traffic provided in the PTT session with the other device.

Abstract: Method and network entities for providing good performance for voice in multiRAB connection for services of a CS+PS call setup (31) without high throughput necessity but providing good throughput for the services needing it. A differentiation of the multiRAB configuration (bearer type, mobility parameters and channel switching timers), based on service detection, is performed either in the RAN either in the CN indicating eventually this detection to the RAN. If the detected service needs high bit rate/throughput (35), the RNC reconfigures the multiRAB configuration (37) so that a bearer type providing high throughput is allocated to said service and the RNC reassigns mobility and channel switching parameters to maximise this throughput and the radio resources. If the service does not require high throughput (34), the RNC configures a bearer type and parameters for mobility and channel switching as specified by the standards to provide good performance (36), low dropped call rate.

Abstract: The present invention provides an effective technique for routing calls to one or more telephony terminals through a traditional telephony line as well as via a packet network. A terminal adapter is provided at a customer premise and supports multiple telephony terminals, which may be associated with the same or different directory numbers.

The incoming calls can be routed to a specific telephony terminal based on incoming call indicia. The terminal adapter can initiate outgoing calls from the supported telephony terminals over the traditional telephony line or via the packet network to the telephony switch. Whether incoming or outgoing calls are routed through the telephony line or the packet network depends on system configuration and existing conditions.
