Abstract: Systems and methods are disclosed for transmitting a text/multimedia message over a bearer interface of a mobile network. A first network element of the mobile network, such as an MSC for a Mobile Terminated (MT) text/multimedia message or a BSS for a Mobile Originated (MO) text/multimedia message, receives a text/multimedia message. The first network element communicates with a second network element of the mobile network using a signaling interface (e.g., an IOS A1 interface) to select a bearer connection on a non-voice circuit-mode bearer interface (e.g., an IOS A5 interface), and routes the text/multimedia message to the second network element over the selected connection on the non-voice circuit-mode bearer interface. The first network element may also select a bearer connection on a voice bearer interface (e.g., an IOS A2 interface) and route the text/multimedia message to the second network element over the selected bearer connection.

Abstract: A mobile station for transferring delay-sensitive data to a wireless communications network is provided with an uplink resource release controller that selectively inhibits release of an uplink resource in order to meet requirements of a delay-sensitive data application, such as a VoIP or streaming application. In one embodiment, the uplink resource release controller causes dummy blocks to be written to a data buffer to prevent initiation of a countdown process. By intelligently controlling resource release, delay-sensitive data may be transmitted in a more reliable fashion, thereby increasing application performance.

Abstract: An access point station responds to a request from a user station for contention-based access of a new traffic flow to a wireless transmission medium by applying a model of the wireless local area network to estimate delay that data packets will experience when delivered through the wireless network, in order to admit the new flow upon determining that admission will not violate quality of service requirements of neither the new flow nor of already admitted flows. For example, the access point station applies the model by determining an average packet inter-arrival rate, solving a system of nonlinear equations to determine probabilities of successful transmission, applying network stability conditions, computing an upper bound on queuing delay for the packets, computing a service delay budget for the packets, and computing an expected fraction of missed packets from the service delay budget.
