Abstract: A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.

Abstract: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.

Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A user equipment (UE) and associated method performs a voice call with a network, including exchanging voice packets, determines an uplink data transmission to be performed concurrently with the voice call and stores the uplink data transmission in a buffer. A base station and associated method performs a voice call with a UE, determines a downlink data transmission for the UE is to be performed concurrently with the voice call and stores the downlink data transmission in a buffer when the UE is a predetermined type. A UE and associated method associates with a first access point (AP), determines first performance characteristics of a connection with the first AP, determines second performance characteristics of a potential connection with a second AP, declares a radio link failure when the second performance characteristics exceed the first performance characteristics to trigger a handover procedure from the first AP to the second AP.

Abstract: A base station and associated method transmits a page to a user equipment (UE) for a call establishment procedure, determines whether an acknowledgement is received in response to the page and when no acknowledgement has been received, determines a number of pages that have been transmitted to the UE for the call establishment procedure, transmits a further page to the UE for the call establishment procedure when the number of pages is less than a page threshold and performs a page failure procedure when the number of pages exceeds the page threshold. In another method the base station transmits a radio resource control (RRC) connection release message to the UE, maintains a context for the UE when an acknowledgement for the RRC connection release message is not received, transmits a first page and transmits a second page when a further acknowledgement for the first page is not received.
