Appl. No.:

13/416017

Inventors:

John B. Preston - Plantation FL, US
George S. Hanna - Miami FL, US

Assignee:

Motorola Solutions, Inc. - Schaumburg IL

International Classification:

H04B 7/185

US Classification:

455 412, 455 413, 455518, 455519, 370471, 370472

Abstract:

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 (), 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 () 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 () the apparatus to have the determined PTT states.

Appl. No.:

12/538505

Inventors:

Robert J. Higgins - Plantation FL, US
John B. Preston - Plantation FL, US

Assignee:

Motorola Solutions, Inc. - Schaumburg IL

International Classification:

H04B 7/00

US Classification:

455 412

Abstract:

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.

International Classification:

H04B 7/00

US Classification:

455 412

Abstract:

A first communication device (e.g., a radio) and a second communication device (e.g., an accessory) implement a wireless device pairing procedure to exchange numerical credentials so that the devices can subsequently form a link for communications using electromagnetic radio signals. The accessory transmits a beacon comprises a pairing request. Upon a user bringing the radio and accessory in close enough proximity, the radio receives the beacon using near-field apparatus included in the radio. In response to receiving the beacon, the radio initiates a pairing procedure, wherein the pairing procedure comprises a data exchange between the radio and accessory, and wherein the beacon and the data exchange comprise a non-propagating radio signal generated using the near-field apparatus. Upon completing the pairing procedure, the radio forms a link with the accessory to communicate using propagating electromagnetic radio signals.

Abstract:

Authentication methods are used to authenticate, a device having an ESN (electronic serial number), a device having an ESN, and/or a user of the devices. In one implementation, device receives the ESN in a near-field signal; derives an authentication result as a function of the ESN and ESN; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN and ESN. In a second implementation, device generates a RAND (random number) and sends the RAND to device over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND from both device and device

International Classification:

H04W 4/02

US Classification:

455 411, 455 412

Abstract:

Two devices () 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 (). 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 (). The conveying of the pairing information can require the first device () to request at least one desired service, to provide a device ID, and to provide an authorization code in a single message (). In response to the single message (), the second device () can either deny the request () or can convey resource use parameters for the desired service and an ID for the second device within a second single message (). Pairing the two devices () can require use of the authorization code and the resource use parameters.

Abstract:

Before hibernating a computing device (), system software components () are notified of an upcoming hibernation process. The notifications are conveyed through an application program interface (API) (). At least a portion of the system software components () can perform one or more pre-hibernation activities to place that system software component () 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 (), the hibernation process can complete. The completed hibernation process creates a snapshot () in nonvolatile memory. The snapshot () saves state information () for each of the system software components (). The state information () is for the ready-to-resume state of the system software components (). The computing device () can be restored after hibernation using a resume process (), which reads the state () information from the snapshot ().
