A method of operating a user equipment in a communications system including at least one cell that is controlled by a radio access node. The method includes maintaining current state information relating to the user equipment, the state information including at least one state information part associated with features for which state information reporting is configured in at least one cell, at least one state information part being associable with a plurality of different values, receiving an indication from the radio access node regarding state information held by the radio access node relating to the user equipment, determining whether to report current state information relating to the radio access node on the basis of the received indication, and reporting a current value associated with at least a given state information part to the radio access node.

A user entity (UE) such as a smartphone is configured to connect to both WiFi and a Long Term Evolution (LTE) cellular network for voice and data services. For voice, the UE supports both Voice over LTE (VoLTE) and Voice over WiFi (VoWiFi). When the UE is connected to VoWiFi and roaming from a first WiFi access point to a second WiFi access point, the UE and Mobility Management Entity in the cellular network carry out a preparatory handover to VoLTE to prevent service loss in the event of an unsuccessful VoWiFi connection from the second WiFi access point.

A communication device for performing a codec rate adaptation comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving a first bit rate recommendation from a first cell; selecting a first codec rate according to the first bit rate recommendation and encoding a first plurality of packets according to the first codec rate; receiving a handover command; performing a handover to the second cell in response to the handover command; transmitting a bit rate query to the second cell after the handover; receiving a second bit rate recommendation from the second cell; and selecting a second codec rate according to the second bit rate recommendation and encoding a second plurality of packets according to the second codec rate.

A system and method of communication, comprising establishing a first connection between the user equipment and a first non-public packet switched network which assigns a first non-public packet switched network address to user equipment; establishing an open signaling channel which communicates between the user equipment and a remote server through a cellular telephone network according to a public switched telephone network address associated with an International mobile subscriber identity; communicating an identification of the first non-public network and the first non-public packet switched network address over the open signaling channel to the remote server; and establishing a real time voice communication from the remote server to the user equipment through the first connection based on a call routed through the remote server to the public switched telephone network address.

The electronic devices described herein enhance a user experience associated with a network connection by transitioning between networks and/or network media. Determinations to switch from one network to another are based on connection quality factors which are collected and compared to defined connection quality thresholds. The connection quality factors are correlated to the quality of the connection, such that the quality of the connection is optimized by switching networks when the connection to one network is poor but the connection to an alternative network may be better. Further, the switching process between networks and/or network media, particularly between 802.11ad networks and other 802.11 networks, is enhanced such that it is substantially seamless, or unnoticeable to the user. The connection quality-based switching determination and the seamless switching between networks provide a consistent, high quality connection and a satisfying user experience.

A communication device for performing a codec rate adaptation comprises at least one storage device for storing instructions and at least one processing circuit coupled to the at least one storage device. The at least one processing circuit is configured to execute the instructions stored in the at least one storage device. The instructions comprise triggering a first transmission of a first MAC CE for a bit rate query or a delay budget reporting, and a second transmission of a data; making a first determination that a transmission priority of the first MAC CE is lower than a transmission priority of the data; allocating the data in a MAC PDU in response to the first determination; and allocating the first MAC CE in the MAC PDU, if a remaining space in the MAC PDU is sufficient for allocating the first MAC CE after allocating the data.

Embodiments of this application provide an application data migration method, including: obtaining, by a network device, a first, second, and third parameter, where the first parameter includes a delay in communication between a terminal device and a first server through a first connection, the second parameter includes a delay in communication between the terminal device and a second server through a second connection, and the third parameter includes a time for synchronizing a context between the first server and the second server; and if the first parameter is greater than a sum of the second parameter and the third parameter, determining, by the network device, that application data on the terminal device needs to be migrated from the first connection to the second connection; otherwise, determining, by the network device, that application data does not need to be migrated from the first connection to the second connection.

A method of wireless communication at a UE is disclosed herein. The method includes transmitting, at a first time instance, an indication of a first measurement on at least one DL-RS associated with a first cell, where the first cell is included in a L1 mobility configured cell set or a L2 mobility configured cell set. The method includes receiving, at a second time instance after the first time instance, an estimated TA associated with the first cell. The method includes performing a second measurement on the at least one DL-RS. The method includes accepting or rejecting the estimated TA for communication with the first cell based on at least one of the first measurement or the second measurement.
