A method and system for dynamically managing wireless pairing of a portable radio device and an accessory are provided. A multi-stage wireless pairing mode applies a first BT pairing stage that utilizes NFC and BT communication, while disabling low-priority, high-current communications of the portable radio device. The second BT pairing stage turns off the NFC pairing, maintains BT, and re-enables the low-priority, high-current communications. Any occurrence of a high-priority, high-current mission critical event disables the multi-stage pairing mode and services the event. User notifications and are dynamically managed to avoid user interference during the pairing.

Thermal mitigation within a converged radio device

A portable communication device provides improved converged operations through the use of a programmable logic array operating as a coexistence module (CEM) interoperating with different processors, different modems, and an attenuation switch. Interference during converged operation is detected, analyzed, and applicable mitigation is applied, thereby enabling converged communications to be established in a mitigated mode until the interference has been removed.

A battery operated portable communication device () provides improved power up of converged functionality managed by a power arbitration module (PAM) (), a baseband processor (BP) (), and an applications processor (AP) (). In response to a control switch () being turned on, the baseband processor generates a time delay and asserts a boot-line to the applications processor which prevents full power up of the applications processor and during which a battery impedance is read, thereby preventing simultaneous power up of the AP and BP. The boot-line from the baseband processor to the applications processor is released once the BP power up is complete and battery impedance is read.

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.
