摘要:
A radio frequency communications system (100) includes wireless terminals (102) and base sites (104). The wireless terminals communicate with the base sites over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. The communication system has a radio frequency channel (400) with time slots (406, 408) for transmission of both delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data (704, 706, 708). Each packet of data transmitted over the wireless channel has a type of service field (900). The type of service field has a precedence or priority value (902) and a service type (904). The priority values are used to determine which packet should be transmitted across the radio frequency channel next and the service type determines the transmission protocol.
摘要:
Before hibernating a computing device (102), system software components (116) are notified of an upcoming hibernation process. The notifications are conveyed through an application program interface (API) (114). At least a portion of the system software components (116) can perform one or more pre-hibernation activities to place that system software component (116) in a ready-to-resume state. Each system software component indicates when it is ready for hibernation. Responsive to receiving the indication from each of the system software components (116), the hibernation process can complete. The completed hibernation process creates a snapshot (122) in nonvolatile memory. The snapshot (122) saves state information (124) for each of the system software components (116). The state information (124) is for the ready-to-resume state of the system software components (116). The computing device (102) can be restored after hibernation using a resume process (130), which reads the state (124) information from the snapshot (122).

Two devices (110, 120) can be determined to be within near field communication (NFC) range of each other. Pairing information for a service can be conveyed over an out-of-band channel (114, 124). The out-of-band channel can be a near field communication (NFC) channel. The service can be a Bluetooth service provided via an in-band (e.g., BLUETOOTH) channel (112, 122). The conveying of the pairing information can require the first device (110) to request at least one desired service, to provide a device ID, and to provide an authorization code in a single message (150). In response to the single message (150), the second device (120) can either deny the request (160, 162) or can convey resource use parameters for the desired service and an ID for the second device within a second single message (164). Pairing the two devices (110, 120) can require use of the authorization code and the resource use parameters.
摘要:
Apparatus, which has a multilayer protocol stack for processing incoming messages, determines PTT state from messages received from a peripheral over a wireless serial communication channel. The apparatus: receives (902), from the peripheral, a sequence of messages comprising a plurality of data messages (e.g., RFCOMM messages), wherein each of the data messages provides an indication of a PTT state for the apparatus, and wherein the sequence of data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data. A pattern detector in the apparatus performs (904) a pattern matching process, within the first two layers of the multilayer protocol stack, to determine the PTT state indicated by each of the data messages and sets (906) the apparatus to have the determined PTT states.
摘要:
Authentication methods are used to authenticate, a device1 having an ESN1 (electronic serial number), a device2 having an ESN2, and/or a user of the devices. In one implementation, device1 receives the ESN2 in a near-field signal; derives an authentication result as a function of the ESN1 and ESN2; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device1 authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN1 and ESN2. In a second implementation, device1 generates a RAND1 (random number) and sends the RAND1 to device2 over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND1 from both device1 and device2.

摘要:
A communication device performs a method for establishing a fast path for signaling priority data. The method includes: establishing a first short range wireless data path to a second communication device for exchanging non-priority data; and establishes a second autonomous short range wireless data path to the second communication device, for exchanging priority data, wherein the second short range wireless data path comprises a wireless serial communication channel such as a radio frequency communication Bluetooth (RFCOMM) channel. An application layer in an upper layer stack of the communication device establishes both the first and the second short range wireless data paths. Non-priority data communicated to the second communication device along the first short range wireless data path is processed by the application layer. However, priority data communicated to the second communication device along the second short range wireless data path bypasses the application layer.

摘要:
Two devices (110, 120) can be determined to be within near field communication (NFC) range of each other. Pairing information for a service can be conveyed over an out-of-band channel (114, 124). The out-of-band channel can be a near field communication (NFC) channel. The service can be a BLUETOOTH service provided via an in-band (e.g., BLUETOOTH) channel (112, 122). The conveying of the pairing information can require the first device (110) to request at least one desired service, to provide a device ID, and to provide an authorization code in a single message (150). In response to the single message (150), the second device (120) can either deny the request (160, 162) or can convey resource use parameters for the desired service and an ID for the second device within a second single message (164). Pairing the two devices (110, 120) can require use of the authorization code and the resource use parameters.
