The assignee for this patent application is Sony Mobile Communications Ab.
Reporters obtained the following quote from the background information supplied by the inventors: "A terminal in cellular mobile communication systems can typically be divided into two entities: an application entity and a modem entity.
"The application entity controls any end-user interactions such as information transmitted to and from the display, the keyboard etc., and it also handles the programs or applications processing information within the application entity. The application entity is connected to the modem entity, wherein the modem entity consists of one or more modems for communication with mobile communication networks or other mobile communication devices.
"The modem entity is controlled by the application entity. For example, for terminal originating transmissions, the application entity controls when the modem shall initiate communication with the network, e.g., to start a voice call or to transfer data over a mobile communication network. Within the application entity, an operating system is running, handling all programs/applications that are executed on the terminal. Applications can, for example, be launched to display and handle calendar, alarm clock, weather information, Internet browsing, social networking, games, etc. Multiple programs/applications can typically be running at the same time within the operating system, even in so-called background mode, meaning that they are updating its information regularly also when the display is showing another program or when the terminal is not used by the end user and therefore is in standby mode.
"Each program/application has, via the operating system, a possibility to utilize the modem entity for voice/data communications. Since each program within the application entity can request modem connectivity via the operating system, and several applications are typically running at the same time, it may result in multiple uncoordinated requests to utilize modem connectivity. Each requested modem activity will activate the modem, and the utilization of the modem connectivity will consume additional battery consumption as compared to if the modem is in standby mode.
"Also, within a mobile communication system the network access possibilities for a modem will be different over time, depending on several parameters. Examples of parameters influencing network access behavior are e.g., terminal mobility, properties of the utilized mobile network technology, terminal-to-base station distance and current network load. In case of a highly loaded and thereby a congested network, a new additional modem access request will further load the network and the network will not be able to expedite the currently active modem requests efficiently. In case of a terminal being close to the edge of a cell, the required output power will be high both in terminal side and network base station side, consuming a high amount of battery current in the terminal and high amount to total capacity in the base station.
"Thus, finding a way to control the modem access to avoid unnecessary modem requests and thereby reduce power consumption and congestion of the modem would be highly sought after."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "With the above description in mind, an aspect of the present invention is to provide a framework for controlling and optimizing the modem access in a mobile communication device which seeks to mitigate, alleviate, or eliminate one or more of the above-identified deficiencies in the art and disadvantages singularly or in any combination.
"By introducing a modem access information framework for communicating with the modem entity, it is possible to distribute information which allows the applications to dynamically adapt their modem access request behavior, reducing impact of congested networks and increasing terminal battery life.
"A first aspect of the present invention relates to a method for controlling the access of at least one application, in an application entity, to at least one modem, in a modem entity, characterized in that said controlling is performed using a modem access information framework, wherein said modem access information framework is collecting modem access information from a modem access interface based on activity of said at least one modem, and distributing said modem access information to any of said at least one application which is subscribing to said modem access information or requesting said modem access information from said modem access information framework.
"The method wherein said distribution may be performed periodically if subscribed to.
"The method wherein said modem access information may comprise at least one network performance indicator (NPI), collected by said modem access interface from said modem entity.
"The method wherein said at least one NPI may be any of: information on average network access latency, block error rate, average transmit rate, receive data rate and received signal-to-noise ratio.
"The method wherein said at least one application may subscribe to at least one of said at least one NPI.
"The method wherein said at least one application may adjust its modem requests based on said modem access information.
"The method wherein said at least one application may schedule when to send a modem request based on said modem access information.
"The method wherein said modem access information may further comprise a modem usage pattern compiled by said modem access information frame work based on one or more of said at least one NPI.
"The method wherein said at least one application may adjust its modem requests based on said modem usage pattern in said modem access information.
"The method may be used in a mobile communication device and said mobile communication device may use the modem access information to notify a base station network about a suitable discontinuous transmission/reception (DRX/DTX) pattern.
"A second aspect of the present invention relates to a mobile communication device comprising an application entity with at least one application, a modem access interface, and a modem entity, connected to said modem access interface, with at least one modem for cellular network access, characterized in that said application entity comprises a modem access information framework connected to said at least one application and to said modem access interface, wherein said mobile communication device is adapted to perform the method as described above.
"Any of the features in the first aspect of the present invention above may be combined, in any way possible, as to form different embodiments of the present invention.
