Abstract: In a communication between a mobile unit (UE) and a gateway general packet radio system (GGRS) support node (GGSN) wherein resource reservations setup protocol (RSVP) capabilities are shared therebetween by a session setup mechanism, preferably session initiation protocol (SIP) in which RSVP capabilities of the UE and GGSN are defined and exchanged. In addition, the SIP is utilized to identify the preferred RSVP mode of operation by negotiations. The SIP is utilized to indicate that: the UE is RSVP capable; those media flows which are based on RSVP; the preferred mode of operation i.e. either UE based RSVP signaling or GGSN proxy based RSVP signaling and to communication a final setup mode for RSVP signaling to the UE from policy control function (PCF). The SIP may also be employed to enable the UE and network to indicate intended quality of service (QoS) protocol during a call setup procedure.

Abstract: The software and hardware within a base station controller and within a mobile station are modified to redefine a flag which is used for controlling communications there between. Additionally, a new flag is created. The system with the modified flag and the new flag allow a channel which is carrying communication control information to be temporarily interrupted so that a data burst may be transmitted on the same channel. In general, the base station controller transmits to the mobile station a plurality of signals which include specified counter values and information relating to a plurality of flags. The preferred embodiment includes six flags and three counters. The flags include the Not Received flag, Received flag, Busy flag, Reserved flag, Idle flag, and Check flag. It is the functionality of the Idle flag which has been redefined. The Check flag is new. The methods for determining when to transmit a data burst are responsive to multiple combinations of the flags.
