Enhanced local access in mobile communications using small node devices

A user equipment (UE) in a cellular telecommunication system, comprising:

• a first communication circuit that receives control-plane data and first user-plane data from a base station (BS) over a first communication link;
• and
• a second communication circuit that receives second user-plane data from a network device using a second communication link,
• wherein the first communication circuit receives a first control-plane message from the BS over the first communication link,
• wherein the second communication circuit establishes the second communication link at a request of the first control-plane message, and
• wherein the first communication link and the second communication link can use different carrier frequencies simultaneously.

A base station (BS) for controlling a user equipment (UE) and a network device in a cellular telecommunications network, comprising:

• a first communication circuit that exchanges user-plane and control-plane data with the UE using a first communication link, and exchanges control-plane data with the network device using a second communication link;
• and
• a processor that controls an establishment and also a release/reconfiguration/handover of a third communication link, which is established between the UE and the network device, at a request of a first control-plane message transmitted to at least one of the UE and the network device using a respective one of the first and second communication links,
• wherein the control unit is further configured to identify user-plane data to be exchanged between the UE and the network device using the third communication link, and
• wherein the first communication link and the third communication link can use different carrier frequencies simultaneously.

A method of communicating using a network device in a cellular telecommunication system, comprising:

• at the network device, receiving a first control-plane message from a base station (BS) over a first communication link;

• at the network device, receiving downlink user-plane data from a server over a third communication link;
• and
• from the network device, transmitting the downlink user-plane data over the second communication link to the user equipment, and
• wherein the second communication link and a communication link for transmitting user-plane data from the base station to the user equipment can use different carrier frequencies simultaneously.
