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.

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

At least one application service is provided to a user equipment (10), utilizing an application service platform (150A) at an access node (110A) of a cellular network and a further application service platform (150A) at a further access node of the cellular network. A parameter is determined which is indicative of a delay associated with transfer of context data from the application service platform (150A) to the further application service platform (150B) in one or more handover messages controlling a handover of the user equipment (10) from the access node (110A) to the further access node (110B). The context data are associated with at least one user session of the at least one application service provided to the user equipment (10). Depending on the determined delay, migration of the user session from the application service platform (150A) to the further application service platform (150B) is controlled.

Accordingly, the disclosure provides a handover optimization method used by a network controller of a transport network and a network controller using the same method. According to one of the exemplary embodiments, the handover optimization method used by the network controller would include not limited to receiving a first data packet which includes not limited to a handover request acknowledgment; transmitting, before receiving a handover execution complete notification which corresponds to the handover request acknowledgement, a second data packet which includes not limited to a user-plane update notification in response to receiving the handover request acknowledgment; and transmitting a third data packet which includes not limited to a user-plane update complete in response to transmitting the user-plane update notification

Disclosed are an event processing method, a User Equipment (UE), and a non-transitory computer-readable storage medium. The method is applied to the UE and includes measuring relevant signals of at least two events; and when the at least two events meet a configured condition, performing handover.

A user equipment has a transmission and reception unit configured to transmit and receive a radio channel to/from a base station via multiple cells configured by carrier aggregation, a simultaneous transmission availability determination unit configured to, in response to an occurrence of an event to transmit an uplink control channel in the multiple cells simultaneously, determine whether the uplink control channel can be simultaneously transmitted in the multiple cells, and a transmission control unit configured to, if the uplink control channel can be simultaneously transmitted in the multiple cells, instruct the transmission and reception unit to transmit the uplink control channel in the multiple cells simultaneously, and if the uplink control channel cannot be simultaneously transmitted in the multiple cells, control transmission of the uplink control channel in accordance with a transmission priority.

The present invention provides a method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes. The method includes transferring event context information associated with a mobile node from a first access node to a second access node.

A method and apparatus are provided for a handover (HO) in an evolved Node B (eNodeB). The method includes receiving a measurement report from a user equipment (UE); transmitting, to a mobility management entity (MME), a handover required message including information indicating whether the HO is for a circuit switched (CS) network or both a CS network and a packet switched (PS) network; and receiving, from the MME, a handover command message. The information is used, by the MME, to split a voice bearer from another bearer.

A method in a first network node for handover preparation of a user equipment of a first category in a wireless communications network. The handover preparation is performed between a first cell served by the first network node and a second cell served by a second network node comprised in the wireless communications network. The first network node sends (301) to the second network node a message comprising information indicating a request for preparation of a handover of the user equipment. The request is specific for user equipment of the first category. The first network node receives (302) from the second network node a message indicating failure to prepare the handover. The first network node interprets (303) the message indicating failure to prepare the handover as an indication that the second network node does not support any user equipment of the first category.

A user entity (UE) such as a smartphone is configured to connect to both Wi-Fi and a Long Term Evolution (LTE) cellular network for voice and data services. For voice, the UE supports both Voice over LTE (VoLTE) and Voice over Wi-Fi (VoWiFi). When the UE is connected to VoWiFi and roaming from a first Wi-Fi access point to a second Wi-Fi access point, the UE and Mobility Management Entity in the cellular network carry out a preparatory handover to VoLTE to prevent service loss in the event of an unsuccessful VoWiFi connection from the second Wi-Fi access point.
