Wireless devices (clients) connect to different access points (AP) in a wireless network. The wireless network may determine that based on, for example, congestion of certain APs that a client should be steered away from a current AP. Steering may be conducted utilizing BSS transition management (BTM) messages to provide the client with a list of network-preferred APs for a transition. Clients may also have one or more preferred APs and may reject the BTM steering message if it does not include at least one client-preferred AP. To prevent rejection of the BTM message, at least one client-preferred AP may be added to the BTM message. To ensure the client is steered to a network-preferred AP, the client is blacklisted from connecting to the client-preferred AP until the client has been steered to a network-preferred AP.

A method for enabling a user terminal to receive packet data in a mobile communication system supporting a packet data service. In the method, a radio network controller receives a session start message from a core network, determines whether or not a frequency area (FA) including the user equipment supports the MBMS service, and transmits a notification message, which contains cell reselection information used when the user equipment moves into an FA supporting the MBMS service, to the user equipment when the user equipment is located in an FA, which does not support the MBMS service.

Disclosed methods and apparatuses advantageously provide for early data forwarding in conditional handover of a User Equipment (UE) (14) in multi-connectivity scenarios. Early data forwarding includes data from secondary nodes (12) of the multi-connectivity.

A terminal device includes receiver circuitry that receives parameter data from a base station in a cellular wireless telecommunication network. The terminal device also includes a storage device that stores an identifier that uniquely identifies the terminal device, and control circuitry that controls the terminal device. The control circuitry controls the terminal device, when operating in an idle mode, to perform cell reselection using at least one cell reselection parameter derived from the received parameter data and the stored unique identifier.

An wireless roaming method and system are provided. The method is applied to an AP and comprises: acquiring terminal information of each wireless terminal of wireless terminals currently accessing the AP; determining a roaming terminal currently in an active state from the wireless terminals according to the RSSI value and the idle duration of each wireless terminal; determining, for each roaming terminal, wireless roaming protocols supported by the roaming terminal; wherein, the wireless roaming protocols include an 802.11k-based roaming protocol, an 802.11r-based roaming protocol, and an 802.11v-based roaming protocol; performing a roaming operation on the roaming terminal according to the wireless roaming protocols supported by the roaming terminal. In the embodiment, the problem of roaming delay, packet loss or disconnection caused by selecting an inappropriate roaming protocol to realize the roaming of the roaming terminal can be avoided to the maximum extent, thereby improving the roaming experience of the user.

The present disclosure relates to methods and apparatus for flexible, security context management during AMF changes. One aspect of the disclosure is a mechanism for achieving backward security during AMF changes. Instead of passing the current NAS key to the target AMF, the source AMF derives a new NAS key, provides the new NAS key to the target AMF, and sends a key change indication to the UE, either directly or through some other network node. The UE can then derive the new NAS key from the old NAS key. In some embodiments, the AMF may provide a key generation parameter to the UE to use in deriving the new NAS key. In other embodiments, the target AMF may change one or more security algorithms.

It is provided a method, comprising supervising if a request to provide user plane connectivity for a user equipment via a second connection through a second anchor entity is received and if the user plane connectivity for the user equipment is provided via a first connection through a first anchor entity, wherein the first anchor entity and the second anchor entity are differently identified; creating the second connection if the request is received; inhibiting transmitting of user plane data on the second connection from creating the second connection until a predefined event happens if the user plane connectivity for the user equipment is provided via the first connection.
