Abstract
A method in a wireless terminal operating in a 3GPP wireless communications network for controlling using MPTCP with a WLAN network, The method comprises receiving from the 3GPP wireless communications network system information comprising a condition for MPTCP with a WLAN network, the condition being associated with mobility characteristics of the wireless terminal. The method further comprises determining a parameter indicative of mobility characteristics of the wireless terminal and disabling MPTCP with a WLAN network if the parameter indicative of mobility characteristics indicates that mobility of the wireless terminal is at or above a value defined in the condition.

A method in a wireless terminal operating in a 3GPP wireless communications network for controlling the wireless terminal using multipoint traffic control protocol (MPTCP) with a wireless local area network (WLAN), the method comprising:
- receiving, from the 3GPP wireless communications network, system information comprising a condition for the MPTCP with the WLAN network, the condition being associated with mobility characteristics of the wireless terminal;
- determining a parameter indicative of the mobility characteristics of the wireless terminal;
- in response to determining that the parameter indicative of the mobility characteristics of the wireless terminal is at or above a value defined in the condition, not allowing the MPTCP with the WLAN network and disabling the MPTCP with the WLAN network;
- determining current mobility characteristics of the wireless terminal;
- and
- permitting a transition of the wireless terminal from a state in which the MPTCP with the WLAN network is not allowed to a state in which the MPTCP with the WLAN network is allowed when the current mobility characteristics of the wireless terminal for the MPTCP with the WLAN network are maintained for a period of time equal to or longer than a defined threshold, wherein the state in which the MPTCP with the WLAN network is allowed, a parallel connection of the 3GPP wireless communications network and the WLAN network is established.
A method in a node of a 3GPP wireless communications network for controlling a wireless terminal operating in the 3GPP wireless communications network and using multipoint traffic control protocol (MPTCP) with a Wireless Local Area Network (WLAN), the method comprising:
- setting a condition for the MPTCP with the WLAN network, the condition being associated with mobility characteristics of the wireless terminal;
- adding said condition for the MPTCP with the WLAN network to system information;
- and
- sending said system information to the wireless terminal, wherein said condition associated with said mobility characteristics causes a transition from a state in which the MPTCP with the WLAN network is not allowed to a state in which the MPTCP with the WLAN network is allowed when the mobility characteristics of the wireless terminal for the MPTCP with the WLAN network are maintained for a period of time equal to or longer than a defined threshold, and wherein the state in which the MPTCP with the WLAN network is allowed, a parallel connection of the 3GPP wireless communications network and the WLAN network is established.
A wireless terminal for a 3GPP wireless communications network, the wireless terminal comprising a processor and a memory, said memory containing instructions executable by said processor whereby said wireless terminal is configured to:
- receive system information comprising a condition for the wireless terminal using multipoint traffic control protocol (MPTCP) with a wireless local area network (WLAN), the condition being associated with mobility characteristics of the wireless terminal;
- determine a parameter indicative of the mobility characteristics of the wireless terminal;
- in response to the determination that the parameter indicative of the mobility characteristics of the wireless terminal is at or above a value defined in the condition, not allow the MPTCP with the WLAN network and disable the MPTCP with the WLAN network;
- determine current mobility characteristics of the wireless terminal;
- and
- permit a transition of the wireless terminal from a state in which the MPTCP with the WLAN network is not allowed to a state in which the MPTCP with the WLAN network is allowed when the current mobility characteristics of the wireless terminal for the MPTCP with the WLAN network are maintained for a period of time equal to or longer than a defined threshold, wherein the state in which the MPTCP with the WLAN network is allowed, a parallel connection of the 3GPP wireless communications network and the WLAN is established.
A node for a 3GPP wireless communications network, the node being configured for controlling a wireless terminal operating in the 3GPP wireless communications network and using multipoint traffic control protocol (MPTCP) with a Wireless Local Area Network (WLAN), the node comprising a processor and a memory, said memory containing instructions executable by said processor, whereby said node is configured to:
- set a condition for the MPTCP with the WLAN network, the condition being associated with mobility characteristics of the wireless terminal;
- add said condition for the MPTCP with the WLAN network to system information;
- and
- send said system information to the wireless terminal, wherein said condition associated with said mobility characteristics causes a transition from a state in which the MPTCP with the WLAN network is not allowed to a state in which the MPTCP with the WLAN network is allowed when the mobility characteristics of the wireless terminal for the MPTCP with the WLAN network are maintained for a period of time equal to or longer than a defined threshold, and wherein the state in which the MPTCP with the WLAN network is allowed, a parallel connection of the 3GPP wireless communications network and the WLAN network is established.
