Method, system and apparatus of wireless local area network (WLAN) communication in conjunction with cellular communication
Some demonstrative embodiments include devices, systems and/or methods of Wireless-Local-Area-Network (WLAN) communication in conjunction with cellular communication. For example, an apparatus may include a wireless communication unit to receive WLAN load information indicating a load of at least one WLAN controlled by at least one access point (AP), and, based on the WLAN load information, to select between connecting to the AP and connecting to a cellular node.
1. An apparatus comprising:
a memory; and
one or more processors configured to cause a user equipment (UE) to:
process wireless local area network (WLAN) information received from an evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN), the WLAN information comprising at least one of information of a WLAN channel utilization and information of a WLAN backhaul; and
determine, based at least in part on a threshold related to the WLAN backhaul, whether to offload communication from the E-UTRAN to the WLAN by connecting to an access point (AP) of the WLAN.
2. The apparatus of claim 1 , wherein the one or more processors are further configured to cause the UE to determine to offload communication from the E-UTRAN to the WLAN based on a comparison between (i) a value based on the WLAN backhaul and (ii) the threshold related to the WLAN backhaul.
3. The apparatus of claim 1 , wherein the information of the WLAN backhaul is based on a WLAN backhaul load.
4. The apparatus of claim 1 , wherein the WLAN information is based on a WLAN available bandwidth.
5. The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to determine to offload communication from the E-UTRAN to the WLAN based on a comparison between (i) a value, based on a WLAN backhaul load and (ii) the threshold.
6. The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to determine to offload communication from the E-UTRAN to the WLAN based on a determination that a value based on a WLAN backhaul load is greater than the threshold.
7. The apparatus of claim 1 , the one or more processors are further configured to:
cause the UE to receive updated WLAN information from the eNB; and
determine to offload communication from the WLAN to the E-UTRAN by disconnecting from the AP of the WLAN based on a determination of whether a condition related to the updated WLAN information occurs.
8. The apparatus of claim 7 , wherein the one or more processors are further configured to:
cause the UE to determine to offload communication from the WLAN to the E-UTRAN based on a determination that the updated WLAN information indicates that a value based on a WLAN backhaul load meets a criterion with respect to the threshold.
9. The apparatus of claim 1 , wherein the one or more processors are further configured to:
cause the UE to receive from the eNB a Radio Resource Control (RRC) signaling message that includes the WLAN information.
10. The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to receive from the eNB cellular load information associated with a load of a cellular network controlled by the eNB.
11. The apparatus of claim 1 , further comprising:
a wireless communication radio to receive the WLAN backhaul information from the eNB;
one or more antennas connected to the radio; and
at least one other processor to execute instructions of an operating system.
12. An apparatus comprising:
means for processing at a user equipment (UE) wireless local area network (WLAN) information received from an evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN), the WLAN information comprising at least one of information of a WLAN channel utilization or information of a WLAN backhaul; and
means for determining, based at least in part on a threshold related to the WLAN backhaul, whether to offload communication from the E-UTRAN to the WLAN by connecting to an access point (AP) of the WLAN.
13. An apparatus comprising:
a memory; and
a processor configured to cause an evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN) to:
include wireless local area network (WLAN) information as part of a radio resource control (RRC) signaling message, the WLAN information comprises at least one of information of a WLAN channel utilization or information of a WLAN backhaul, wherein at least a threshold related to the information of the WLAN backhaul is configured to assist the UE in determination whether to offload communication from the E-UTRAN to a WLAN; and
transmit the RRC signaling message to a user equipment (UE).
14. The apparatus of claim 13 , wherein the information of the WLAN backhaul is based on a WLAN backhaul load.
15. The apparatus of claim 13 , wherein the WLAN information is based on a WLAN available bandwidth.
16. The apparatus of claim 13 , further comprising a wireless communication radio to transmit the RRC signaling message, and one or more antennas connected to the radio.
17. The apparatus of claim 1 , wherein determining whether to offload communication from the E-UTRAN to the WLAN is further based on a determination of whether a condition pertaining to the channel utilization occurs.
18. The apparatus of claim 12 , wherein determining whether to offload communication from the E-UTRAN to the WLAN is further based on a determination of whether a condition pertaining to the channel utilization occurs.
