Abstract: Devices and methods for handling phone calls. One device is a user equipment (UE) configured to establish a connection with a first evolved Node B (eNB). A method includes transmitting an invite signal to a further UE for a Voice over LTE (VoLTE) call, receiving an accept signal from the further UE, receiving a fail signal from the first eNB that a dedicated bearer is unavailable, generating a trigger signal in response to receiving the fail signal and transmitting the trigger signal to the first eNB. Another device is a base station (e.g., eNB) that receives a VoLTE call request from a UE, determines whether the eNB has sufficient resources to provide a dedicated bearer. When it is determined the eNB has insufficient resources, the eNB determines whether a further eNB has sufficient resources to provide the dedicated bearer, and determines whether the UE can connect to the further eNB.

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: 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 network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.
