Abstract:

A method for transmitting packetized data in a cellular communication system uses a dynamic channel assignment scheme. In this aspect of the invention a data control channel is used in addition to the data traffic channel. The mobile end system uses the data control channel to send a request for assignment of a channel for transmission of data--such as a particular frequency/time-slot in a TDMA system. The network responds with the identification of a particular channel that may be used for a particular time period to transmit data. In this aspect of the invention there is no dedicated channel that is used for data transmission. Rather, the network determines a channel that will be free for the specified time period and assigns it for data transmission.

Abstract:

Systems, software, and methods are disclosed herein for implementing a template rendering engine that facilities enhanced event handler attachment when executed by a processing system in the context of a browser application. The template rendering engine examines hypertext markup language (HTML) code downloaded to the browser for templates encoded in the HTML code. When a template is encountered in the HTML code, the template rendering engine examines the template for event handling information indicative of at least an element to render in a web page and an event handler to attach to the element in the web page. The template rendering engine then produces new HTML code for the browser to consume when rendering the web page, the new HTML code comprising the element and the event handler attached to the element.
