Abstract

Some demonstrative embodiments include devices, systems of User Equipment (UE) centric access network selection. For example, a cellular node may include a transmitter to transmit to a User Equipment (UE) a cellular communication message over a cellular communication medium, the message including a value of a predefined parameter, which is based on a cellular network load of a cellular network controlled by the cellular node.

Claims

1. A cellular node comprising:

a transmitter to transmit to a User Equipment (UE) a cellular communication message over a cellular communication medium, the message including UE-assistance information to assist in access network selection, the UE-assistance information including a value of a predefined parameter, which is based on a cellular network load of a cellular network controlled by said cellular node, the value of the predefined parameter is comparable to a non-cellular network load of at least one non-cellular network.

2. The cellular node of claim 1, wherein said predefined parameter comprises a resource allocation parameter representing an amount of resource for allocation by the cellular node to said UE.

3. The cellular node of claim 2, wherein said resource allocation parameter comprises a maximal resource block parameter representing a maximal number of resource blocks for allocation by the cellular node to said UE.

4. The cellular node of claim 1, wherein said predefined parameter comprises a load threshold parameter comparable to a non-cellular network load parameter of a non-cellular network.

5. The cellular node of claim 4, wherein said load threshold parameter comprises a Wireless-Local-Area-Network (WLAN) load threshold parameter.

6. The cellular node of claim 1, wherein said predefined parameter comprises a cellular network signal strength threshold parameter.

7. The cellular node of claim 1, wherein said cellular communication message comprises a Radio-Resource Control (RRC) signaling message.

8. The cellular node of claim 7, wherein said RRC signaling message comprises a RRCConnectionConfiguration message.

9. The cellular node of claim 1, wherein said cellular communication message comprises a System Information block (SIB).

10. The cellular node of claim 1 comprising an Evolved node B (eNB).

11. A User Equipment (UE) comprising:

a Wireless Local Area Network (WLAN) transceiver;

a cellular transceiver to receive from a cellular network a cellular communication message including a value of a WLAN load threshold parameter; and

a controller to control access network selection of said UE based on a predefined selection criterion applied to the load threshold parameter and a WLAN load of a WLAN.

12. The UE of claim 11, wherein said selection criterion is a function of a measured received signal strength indication (RSSI) measured by said UE with respect to said WLAN, an RSSI threshold, the WLAN load of said WLAN and said WLAN threshold.

13. The UE of claim 12, wherein said selection criterion is based on a ratio between a first difference between the measured RSSI and the RSSI threshold, and a second difference between the WLAN load of said WLAN and said WLAN threshold.

14. The UE of claim 11, wherein said selection criterion is a function of a WLAN bandwidth of said WLAN, the WLAN load of said WLAN and said WLAN threshold.
