Reducing interference and energy consumption for FEMTO base stations

A method comprising:

• receiving, by a base station in a wireless communications network, a setup request;
• performing an enabling handshaking between a node of the wireless communications network and the base station, wherein the wireless communications network connects at least one neighboring base station and the base station enabling a user device associated with the base station and/or the at least one neighboring base station to be able to be reassigned between the base station and the at least one neighboring base station;
• wherein said setup request is received via the at least one neighboring base station from the user device associated with the base station;
• and
• in response to successful completion of said enabling handshaking, enabling wireless transmission and wireless reception of the base station, wherein the base station is located in a coverage area of the at least one neighboring base station.

An apparatus comprising one or more processors and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors to cause the apparatus to perform at least the following:

• transmitting and/or receiving a wireless communication signal;
• determining whether there is an active wireless communication data session, based on the transmitting and receiving of the base station, between said apparatus and a user device while the user device is assigned to the apparatus;
• in response to determining no active wireless communication data session between the apparatus and a user device while the user device is assigned to the apparatus, disabling said wireless transmitting and said wireless receiving while maintaining a connection between said apparatus and a node of the wireless communications network,
• wherein the determination of no active wireless data session comprises at least one of the user device having left the coverage area of the base station, the active wireless session has been terminated, and no traffic is transmitted over a predefined period,
• receiving, by the apparatus in the wireless communications network, a setup request,
• performing an enabling handshaking between said node of the wireless communications network and said apparatus, wherein the wireless communications network connects at least one neighboring base station and said apparatus enabling a user device associated with the apparatus and/or the at least one neighboring base station to be able to be reassigned between the apparatus and the at least one neighboring base station, and
• in response to successful completion of said enabling handshaking, enabling said wireless transmitting and said wireless receiving, wherein the base station is located in a coverage area of the at least one neighboring base station,
• wherein said setup request is received via the at least one neighboring base station from the user device associated with the apparatus.

An apparatus comprising one or more processors and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors to cause the apparatus to perform at least the following:

• receiving a setup request via a node of a wireless communications network;
• performing an enabling handshaking between said node of the wireless communications network and the apparatus, wherein the wireless communications network connects at least one neighboring base station and the apparatus enabling a user device associated with the apparatus and/or the at least one neighboring base station to be able to be reassigned between the apparatus and the at least one neighboring base station;
• wherein said setup request is received via the at least one neighboring base station from the user device associated with the apparatus;
• and
• in response to successful completion of said enabling handshaking, enabling wireless transmission and wireless reception of the apparatus, wherein the apparatus is located in a coverage area of the at least one neighboring base station.

A computer program product embodied on a non-transitory computer-readable medium storing a computer program that, when being executed by a computer, is configured to provide instructions to control or carry out:

• in a wireless communication network wherein a base station is in communication with at least one node of the wireless communication network through a connection, determining whether there is an active wireless communication data session, based on wireless transmission and reception of the base station, between the base station and a user device while the user device is assigned to the base station;
• in response to determining that there is no active wireless communication data session between the base station and the user device, disabling all wireless transmitting and wireless receiving of the base station while maintaining the connection between the base station and the at least one node of a wireless communication network, wherein the determination of no active wireless data session comprises at least one of the user device having left the coverage area of the base station, the active wireless session has been terminated, and no traffic is transmitted over a predefined period;
• receiving a setup request through the connection to the at least one node of the wireless communication network,
• performing an enabling handshaking between the base station and the at least one node of the wireless communication network, wherein the wireless communication network connects at last one neighboring base station and the base station to enable the user device assigned to the base station and/or the at least one neighboring base station to be reassigned between the base station and the at least one neighboring base station;
• and
• in response to a successful completion of the enabling handshaking, enabling wireless transmitting and wireless receiving of the base station, wherein the base station is located in a coverage area of the at least one neighboring base station;
• wherein said setup request is received via the at least one neighboring base station from the user device assigned to the base station.
