Abstract: Systems, methods, and computer-readable media for managing end-to-end security over an IP Multimedia Subsystem (IMS)-enabled network are provided. A first subscriber module accesses an IMS network via an access gateway as a roaming network. The roaming network routes a request for a session from the first subscriber module from its P-CSCF to the I-CSCF of a third-party home network. The third party home network, in turn, routes the request to an S-CSCF implemented at the subscriber's home network, which comprises a second subscriber module. In this way, the session between the two subscriber modules is managed by the subscriber's S-CSCF rather than by a carrier's IMS network, and the subscriber may administer the security relationship without reliance on the carrier or the third party.

Abstract: A method of displaying information on a display of a handheld electronic device includes steps of determining a target area onscreen to be visually magnified and causing a shape-changing zone of the display to change shape in the target area to visually magnify information displayed in the target area. The array of shape-changing zones on the touch-sensitive display can be independently actuated to form a magnifying lens over any onscreen object of interest. For example, this lens can be used to magnify a selected portion of a map, a portion of text or a specific point of interest. The lens can be used to magnify a route displayed on a map, or simply to zoom in on the current location of the device as displayed onscreen.

Abstract: A peripheral for an electronic device having a speaker is provided. The peripheral includes an input device for placement proximal to the speaker for receiving audio information from the speaker. The peripheral includes an output device connected to the input device that is positioned distal from the input device and away from electromagnetic signals generated by the device. The output device presents the audio information to a hearing aid proximal to the output device. The output device is positioned at a distance such that the electromagnetic signals experienced by the input device is less than the signals experienced by the hearing aid. As a result, deleterious effects of signals otherwise experienced by the hearing aid are reduced.

The one or more routines include a cryptographic module adapted to encrypt first information to create the first encrypted information and decrypt the second encrypted information to obtain second information. In addition, a communication system that includes the reader device and a computing device, wherein the reader device and computing device are able to wirelessly exchange information in a secure manner.

Abstract: Two or more connection profiles stored in a wireless device are partitioned into two or more groups, each group having a scanning policy associated therewith. A scanning policy of a group determines how often scanning for wireless local area networks matching any profile in that group is conducted. One or more factors may be taken into consideration when determining how to partition the profiles into groups, including, for example, a connectivity history of the wireless device.

Abstract: A method and apparatus for data encoding such as 3 to 4 encoding (base64, uuencode etc.) is provided. Bytes of data to be encoded having negative values are made positive while preserving the information to be encoded. The positive values may be manipulated by addition (e.g. to a common store) and bit shifting to efficiently obtain encoded data such as by indexing an encoding alphabet.

Abstract: In one embodiment, a scheme is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. Upon detecting that a cause code has been returned by a node disposed in a wireless packet data service network, a structure is interrogated to determine if the cause code is mapped to a flag relating to the device's data session retry mechanism. Responsive to determining that the received cause code is mapped as a critical cause code, the data session retry mechanism of the mobile communications device is disabled so that further signaling messages towards the network are prevented.

Abstract: Apparatus (58), and an associated method, for facilitating delivery of network-specific dialing codes to a mobile node (12). Broadcasts of the network-specific dialing codes are scheduled by a broadcast scheduler 64 embodied at a cell broadcast center (38). Signals containing the codes are broadcast and detected by the mobile node (12), thereby to download the values to the mobile node. And, the downloaded dialing codes are indexed (88) together with the dialing codes normally used by the mobile node (12) to call the corresponding service centers (44). Subsequently, when a call is placed to a service center, the dialing codes are transposed (94), if necessary, to permit the call to a designated service center (44) to be completed.

Abstract: An apparatus, and an associated methodology, for identifying to a circuit-switch-connected mobile station with an indication of packet-service capabilities available to a mobile station. A message generator at the network generates a message that includes an indication of the network-entity capabilities with respect to packet communications. A field of the message identifies the packet-service capabilities. A message is sent by the network and detected by a detector of the mobile station. A report is formed indicative of the value contained in the delivered message, and a user display displays an indication of the detected information.

Abstract: An apparatus, and an associated methodology, for facilitating paging of a mobile station pursuant to a two-step paging procedure. A unique identifier of the mobile station that is to be paged is hashed into a first group of hashed values and at least a second group of hashed values. The first group of hashed values are used by page message generator to generate a page on a first paging channel. And, the second group of values are used by a page message generator to generate a page on a second paging channel. All of the bits of the unique identifier are sent to page the mobile station. The mobile station determines therefrom whether the mobile station has been paged.

Abstract: A method and apparatus for regulating Tx power in a multi-rate mobile device transmitter containing signal dependent gain stages. A data rate and signal format indicator signal corresponding to the transmitted signal, and a desired reference power signal are fed to a mapper that outputs a calibration value based on the desired reference power level at the antenna. The calibration value controls the power amplifier gain characteristics in real time.

Abstract: By altering existing code to wrap debugging items with runtime conditional statements, the debugging items may remain in commercial builds of code. Execution of a given conditional statement, wrapping a particular debugging item, may require a read of a particular location in an expandable and organized table such that execution of the particular debugging item is dependent on the value stored in the particular location in the table. By storing appropriate values in the table, a very focused debugging operation may be carried out. When implemented on a mobile communication device, such a focused debugging operation may be considered to conserve limited memory resources and reduce radio costs when compared to an unfocused debugging operation, which can create a large log file that is difficult to store and expensive to transmit.
