Problems solved by technology
[0005] If the PLMN is unable to provide the originally requested QoS due to congestion in either the radio network or the packet-switched core network, and the user accepts a lower QoS, the applications the user wishes to run will perform poorly
For example, lower quality of service will result in lower transmission speed or higher bit error rate

Embodiment Construction
[0017] Turning now to the drawings, wherein like symbols indicate like or similar parts in the various drawings. discuss first figure 1 , which shows a block diagram of a portion of a public land mobile network (PLMN) 2 suitable for packet-switched data communications. The PLMN 2 includes a radio network 4 and a core network 6 . Although the PLMN 2 is shown operating according to third generation standards including the Universal Mobile Telecommunications System (UMTS) standard to which reference will be discussed below, those skilled in the art will appreciate that other standards (eg GSM / GPRS) and specifications The principles of the present invention can also be used.
[0018] In performing packet-switched data communication in a mobile telecommunications environment, data packets are transmitted from a server located in an external network 12 (eg the Internet) to a user equipment (UE) 10 of a user via the wireless network 4 and the core network 6 . User equipment 10 com...

A system (2) and method for allocating system resources to provide a selected quality of service in connections with data communications. A mobile subscriber station (10) requests a first quality of service level (52) for a data communication session. In response to determining that system resources for providing the first quality of service level are unavailable (54), the system allocates resources for providing the second quality of service level for the data communication session (58). Thereafter, during the communication session, the system monitors the availability of system resources (62). If system resources for providing the first quality of service level become available, the system allocates system resources for use by the subscriber station, and upgrades or downgrades the communication session accordingly (64).
Description
technical field [0001] The present invention relates generally to data transmission in telecommunication networks, and more particularly to dynamically modifying the quality of service on packet-switched communications. Background technique [0002] Originally, mobile telecommunication networks were mainly designed for voice communication in a wireless environment. As wireless telecommunications systems develop, additional voice and messaging services and features are added. In addition, a newer generation of wireless telecommunication systems based on packet switching technology is being designed to handle a wider range of data communication services. In contrast to analog and digital cellular protocols designed primarily for voice communications, these services permit the transfer of large amounts of data at higher speeds than previously achievable, the possibility of maintaining a consistent connection to the network, and the ability to process in an efficient manner Ca...
