摘要:
The invention concerns a method (500) for tracking sequence numbers. The method includes the steps of detecting (512) an error in a first set of data (120), determining (514) a range (144) of possible sequence numbers (122) for a second set of data (120) and using the range of possible sequence numbers, producing (516) a block code (126) for the second set of data in which the block code is used to verify that one of the range of possible sequence numbers is a correct sequence number for the second set of data.

This document describes various techniques for implementing local voicemail on a mobile device. These techniques may include enabling the mobile device to answer a voice call, record audio of the voice call to provide a voicemail file, and store the voicemail file to local computer-readable media. A locally stored voicemail file may be associated with relevant data, exposed via the associated data for local processing, and/or manipulated through a user interface of the mobile device.

An InterProcessor Communication (IPC) Protocol network (100) includes at least one IPC client (102) and an IPC server (108). The IPC protocol allows for the IPC client (102) to register with the IPC server (108) which will provide the means for the two to communicate freely without any limitations on what software architectures, operating systems, hardware, etc. each depend on. The IPC protocol in one embodiment of the invention provides for dynamic IPC node configuration in a server based IPC communication management framework.
摘要:
A multi-camp mobile communication device (100) includes a first radio modem (102) and a second radio modem (104). Each modem is designed to communicate with a respective communication system (110, 112). Upon engaging in an interconnect call (204) over the first modem with the first communication system, the multi-camp mobile communication device receives a dispatch call at the second modem (206) from the second communication system. The multi-camp mobile communication device replies to the dispatch call with a pre-recorded message (208). The dispatch calling party may respond to the pre-recorded message with a voice message that is recorded by the multi-camp mobile communication device (210, 212).
摘要:
A device and method for receiving communications associated with a second communication service while actively communicating using a first communication service is disclosed. The method includes receiving an incoming call associated with a second communication service at a wireless device (104). The second communication service is either different than the first communication service currently being used by the wireless device (104) or is a similar communication service using a different network than the first communication service. The method also includes notifying a user of the wireless device (104) of the incoming call associated with the second communication service.
摘要:
Systems (100 or 300) and methods (400 or 500) are provided for selecting a post-compression waveform from a post-compression waveform table (106) and supplying it to a synthesis engine (108). The post-compression waveform is based upon a set of post-compression coefficients determined by generating a frequency-domain representation of a periodic signal, the representation including at least one pre-compression frequency-domain sample (204), and performing a threshold-based compression of the pre-compression frequency-domain samples. Systems and methods also include indexing and storing (502) post-compression coefficients in a post-compression coefficient table (102), generating (506) a post-compression waveform based upon the set of post-compression coefficients, and placing (508) the post-compression waveform in the table prior to the selecting (510). The system and method also include performing (504) a read-ahead operation on a sound file before selecting the post-compression waveform, the read-ahead operation indicating the post-compression waveform to be selected and supplied to the synthesis engine.

The invention relates to a system and method for use in wireless packet data mode communications for facilitating communications between one or more remote devices and a base target device. The invention provides a high priority access channel (406) that can be utilized by specifically enabled packet data capable remote units (102), to perform random access channel request from a base station (106) when there is overloading on the standard communication channel (404).
摘要:
A method of scaling polyphony can include identifying music data to be played (415), wherein the music data indicates instruments to be used and each instrument has an assigned priority. A measure of polyphony needed to play the music data can be compared with polyphony of a sound generating device (425). If the measure of polyphony exceeds the polyphony of the sound generating device, the music data can be played without using one or more instruments indicated by the music data according to the assigned priorities (440, 460).
摘要:
A method for transferring messages between a first processor (102) and a second processor (104) includes the step of requesting an empty message buffer (106) from the first processor or master processor (102). The first processor (102) sends an empty message buffer pointer (108) which the second processor uses to locate the allocated memory within the shared memory (112). The second processor (104) then loads its message in the allocated memory area and sends the message (110). After receiving the message, the first processor (102) releases the allocated memory area found in shared memory (112) so that it can be used in the future. An electronic device such as a radio communication device that uses the shared memory scheme is also described.
摘要:
An IPC protocol/network allows for intelligent targeting of nodes in order to reduce overhead and provide for improved power management. The IPC server keeps track of the IPC network's node activity and using an operational state table (2000) it can determine which node can handle a service request (e.g., MP3 decode). By keeping track of the current operational condition of the nodes within the network, the processors can have better battery life and application latency can be improved. The IPC server will keep track not only of which nodes can handle which services, but it will also know which node can handle the service request given its knowledge of the operational state of each of the nodes.
