  • Patent number: 10721789
    Abstract: A method of handling multipath connections in a Public Land Mobile Network (PLMN). The method comprising the steps of determining within the PLMN that a path, established across the PLMN, is a backup path of a multipath connection and providing an explicit indication to one or more nodes within the PLMN that the path is a backup path using a protocol layer that is otherwise unaware of the multipath connection. The method further comprises the step of, at the or each notified node, applying a handling to the path that is differentiated from the handling of non-backup paths.

  • Publication number: 20200187092
    Abstract: A method performed by a user equipment, UE, is disclosed. The method comprises determining (402) in response to an event (401) that triggers the UE to perform an access request to a radio access network, RAN, an access category to apply. The UE performs a barring check (403), applying the access category. Upon determining that access is not barred based on the access category, the UE sends (405) the access request to a network node in the RAN, the access request including the access category. The network node decides whether to accept or reject the access request based on the access category.

  • Publication number: 20200120728
    Abstract: A method for establishing a radio resource control connection between a first wireless device and a radio network node, comprises transmitting a request for a radio resource control connection towards the radio network node from the first wireless device to a second wireless device. Then, the second wireless device forwards the request for a radio resource control connection towards the radio network node to the radio network node. The forwarding by the second wireless device uses an already established radio resource control signaling connection between the second wireless device and the radio network node.

  • Publication number: 20200120741
    Abstract: According to an aspect, a wireless device determines, while in an RRC Inactive state, that a Radio Access Network Notification Area Update, RNAU, is needed. The wireless device further evaluates whether there is any other cause for resuming an RRC connected state, in addition to the need for the RNAU. The wireless device transmits an RRC Resume Request message to the network, in response to the determining. The RRC Resume Request message includes a cause indicator indicating an RNAU as a cause for resuming a RRC Connected state in the event that said evaluating identifies no other cause for resuming the RRC connected state.

  • Publication number: 20200084691
    Abstract: A method performed by a User Equipment (UE) for controlling a data transmission over a bearer in a wireless communications network is provided. When the bearer is established, the UE determines (1102), an access category for the data to be transmitted over the bearer. The UE associates (1104) the determined access category with the bearer. When the data is to be transmitted over the bearer, the UE performs (1106) barring check of the access category associated with the bearer. When the access category associated with the bearer is barred, the UE decides (1108) to not transmit the data, and when the access category associated with the bearer is not barred, the UE decides (1110) to initiate a procedure to transmit the data over the bearer.

  • Patent number: 10454827
    Abstract: A method performed by a network element in a communication network comprises inspecting traffic between a radio device and the communication network. The method also comprises, based on said inspecting, determining that the traffic is part of a TCP subflow of an MPTCP connection. The method also comprises, based on said inspecting, calculating a ratio of how much data is transmitted in the subflow in relation to the total amount of data transmitted in the MPTCP connection over a predetermined time period. The method also comprises observing that the calculated ratio is below a reference ratio. The method also comprises, based on said observing, performing an action for preventing congestion in the communication network.

  • Patent number: 10342041
    Abstract: There is provided access to a communications channel in a wireless communications network. Stations (STAs) associated with an access point (AP) are grouped in at least two groups of STAs, each group being associated with a minimum transmission power level needed by the AP to communicate with the STAs in that group. A first time interval is allocated for a first group of STAs associated with highest minimum transmission power to access the communications channel concurrently with a third time interval being allocated by another AP for a third group of STAs associated with lowest minimum transmission power level needed by said another AP to communicate with the third group of STAs to access the communications channel.
