Disclosed are a user terminal device and a control method therefor. The control method for a user terminal device according to the present invention comprises the steps of: determining state information of a satellite device connected with a user terminal device when a call request message is received from another terminal device; determining communication configuration information with the another terminal device on the basis of the state information of the satellite device, and transmitting a call response message including the communication configuration information to the another terminal device; and receiving audio data from the another terminal device according to a communication scheme corresponding to the communication configuration information. Therefore, in comparison with the prior art, the present invention can reduce a call negotiation time between user terminal devices, and thus reduce a call cost.

Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.

Methods and systems for registering a phone device on a synthetic communication network are described. One implementation receives a request to connect the phone device to a synthetic communication network that transmits messages over a data network using one or more phone numbers from a voice network. A phone number and a country code associated with the phone device to be used for communications over the synthetic network are obtained. The phone number is normalized to a standard format distinguishing the resulting normalized phone number from international phone numbers using the synthetic network. Before the phone device is registered, an association between the normalized phone number and the phone device is verified by sending a verification message addressed to the phone device that loops back to the phone device. If the phone device confirms the verification as authentic, an authorization allows the phone device to communicate over the synthetic network.

In modern networks, RRU and BBU equipment of an access point site typically handles traffic from a single sector. An RRU-BBU pair process that traffic (often limited to a single spectrum from a single sector) according to implemented capabilities and other equipment located further upstream perform functions that rely on information from multiple sectors. An integrated device (e.g., white box) can integrate the functionality of multiple RRU (or NR in 5G) and the functionality of multiple BBU (or DU/CU splits in 5G), which can reduce implementation footprint, costs, and can provide related services more efficiently without going upstream.

A method and transition device for enabling communication of data between a remote radio unit and a central baseband unit in a wireless network. When detecting a first interface configuration used by the remote radio unit and a second interface configuration used by the baseband unit, the transition device configures interface functions, based on the first and second interface configurations. The interface functions are selected from a set of predefined interface functions associated with different interface configurations. The transition device then establishes a data flow between the remote radio unit and the central baseband unit over the transition device, and performs conversion between the first interface configuration and the second interface configuration for data communicated in the data flow, using the selected interface functions.

A network node, a communication device and methods therein, for handling dynamic uplink/downlink, UL/DL, subframe configurations when operating in Time Division Duplex, TDD. The network node obtains capability information indicating whether the communication device supports carrier aggregation and/or frequency band combination, and also indicating whether the communication device supports simultaneous reception and transmission of signals on different carriers or frequency bands. The network node then determines UL/DL subframe configurations for the communication device based on the obtained capability information such that the communication device is to use different UL/DL subframe configurations for different carriers or frequency bands, when certain conditions are fulfilled.
