A mechanism for a bidirectional reservation procedure within an in-band signaling mechanism gives symmetric real-time services running on mobile devices, which are used to support different access technologies in dynamic, mobile, wireless IP networks where the quality of the node connectivity can sometimes be unpredictably time-varying, the possibility to mutually reserve, monitor and adapt resources and service parameters for upstream and downstream direction along a communication path. The mechanism optimizes reservation mechanisms, especially for adaptive real-time services in wireless and wireless ad-hoc networks, by making use of a dynamic bidirectional reservation in-band signaling approach.

An apparatus and method are disclosed of a wireless system for customers to interact with attendants (e.g waiters) in restaurants. The system provides for a computing system that transmits electronic menus to wireless portable digital assistants (PDA's) and enables customers to place orders and make real-time service requests. For example, the customer is able to select food items from the menus, indicate preparation instructions for each food item, send comments to the attendants, and request drink refills. The customer is able to check on the status of food preparation via the PDA and observe the food being prepared by a camera link. Upon finishing the meal the restaurant can transmit an electronic bill to the customer.

A system and method for enhancing service over a high-speed downlink packet access (HSDPA) service in a cellular communication network includes informing a UE of the cells in an HSDPA active subset of cells. The US makes a measurement of the cells and selects a best cell for switching. The UE determines whether the best cell is an intra-node B cell or inter-node B cell with the serving cell from the network. If the best cell is an intra-node B cell, the UE signals the node B of the best cell, the node B switches to the best cell directly and UE receives the data from the target cell directly, and then Node B reports the switch to a radio network controller (RNC) that completes the final switching to the best cell by the RNC. If the best cell is an inter-node B cell, the UE signals the RNC of the best cell directly, whereupon the RNC sends the UE an acknowledgment without waiting for the completeness of the network configurations. The RNC re-routes data to the best cell, and the UE switches to the best cell after receiving the acknowledgment.

The underlying invention generally relates to the field of mobile computing in a wireless mobile networking environment with distributed multimedia applications (130). More specifically, it is directed to the field of Quality-of-Service (QOS) management for adaptive real-time services running on mobile devices and an End-to-End Negotiation Protocol (E2ENP) based on a novel usage of a session-layer protocol (SIP) in conjunction with extensions of a session description protocol implementation (SDP, SDPng) and the Extensible Markup Language (XML) for defining user profile and terminal capability information which allow to enforce and use hierarchical QOS Contract specifications. Thereby, said End-to-End Negotiation Protocol (E2ENP) is applied to derive negotiable information, which enables a prenegotiation, fast negotiation and a fast, dynamic re-negotiation of the end-to-end quality and capabilities for a telecommunication session, for multiple configurations of two or a multiplicity of end peers and/or middleware in a consistent, reliable, and incremental way by enabling the mobile applications to efficiently and timely react to QoS violations. Furthermore, the invention pertains to the concept and realization of a novel E2ENP User Agent (128) which encapsulates the signaling part of E2ENP and expresses the information to be negotiated in an interchangeable format in such a way that heterogeneous applications (130) can easily agree on a reference model applied to orchestrate local, peer, and network resources according to the preferences and profiles of the respective user in a coordinated manner. According to one embodiment of the invention, the employed E2ENP sessionlayer protocol Application Programming Interfaces (101a-e) are independent of the actually used session-layer protocol and session description protocol implementations.

A method and equipment is used to transmit and/or receive time delay-intolerant information over a communication system. The information is transmitted in aggregated form. A plurality of packets representing time delay-intolerant information is combined to form an aggregate packet. The aggregate packet is formed based on user service requirements while maintaining time delay requirements of the information. The size of the aggregated is formed from a negotiation between the transmitting equipment and receiving equipment. Because of the use of an aggregated packet less scheduling of packets is done and the aggregated packet can be transmitted at a rate different than the fixed rate of the time delay-intolerant information. The equipment comprises transmit equipment and receive equipment. The transmit equipment contains an aggregator that combines a plurality of packets based on user service requirements. The packets to be transmitted are retrieved at the fixed rate of the time delay-intolerant information. The size of the aggregate packet can be determined on a static or dynamic basis. The receiving equipment contains a de-aggregator circuit that receives aggregated packets and generates individual packets from the received aggregated packet. The generated individual packets are retrieved from the de-aggregator at the fixed rate of the time delay-intolerant information.

A method and system for reducing delay in wireless communications by use of a burst based access and assignment system. The method for setting up a communication channel uses short burst(s) (essentially a slot of a time frame). Time is saved by keeping the uplink and downlink channels flexible and independent of each other. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. The result is less delay to the mobile user and greater usage density for the wireless service provider.

The method concerns multicast service delivering through the UMTS and GSM networks. For this aim is given higher priority to an opportune subset of all the real-time services with guaranteed bandwidth transmissible by the network. This subset is named IS-MBMS (Immediate Streaming-Multimedia Broadcast Multicast Service). A certain amount of physical resources is reserved in all the system for the IS-MBMS services; not real-time services can be transmitted on the reserved resources when not used by the IS-MBMS ones. The reserved resources allow for transmitting the IS-MBMS services with minimum bit-rate, at least. The network announces in the service area that an IS-MBMS content becomes available; in reply one or more subscribed users transmit a request for joining a multicast group for that service. The network transmits a notification message on a multicast channel to give to the joined users useful information of how get the announced service, i.e.: Service-Id, RB parameters, etc. The IS-MBMS content is transmitted immediately on a point-to-multipoint channel set-up in each involved cells, even if there are zero recipients in the cell. Content is transmitted in parallel in different cells, leading to service continuity, and the mobile station can perform soft combining. During the IS-MBMS content delivery the network can count in each involved cell the number of subscribed users joined to the transmitted IS-MBMS service. The network switches from point-to-multipoint to point-to-point or to no transmission depending on the result of counting and on a fixed threshold. Alternatively the network, parallel to the content delivery, can execute a checking procedure to see if there are joined users in a cell: in this case the point-to-multipoint channel is switched to no transmission (fig. 3).
