Embodiment

[0310] Embodiments further include a method implemented in a communication system comprising a host computer, a base station, and a user equipment (UE). The method includes, at a host computer, receiving from a base station user data originating from a transmission that the base station has received from a UE. The UE performs any step of any embodiment described above for the UE.

[0311] In some embodiments, the method further comprises, at the base station, receiving user data from the UE.

[0312]In some embodiments, the method further includes, at the base station, initiating a transmission of the received user data to the host computer.

[0313] Generally, all terms used herein are to be interpreted according to their ordinary meanings in the relevant technical field, unless a different meaning is clearly given and / or implied from the context in which they are used. All references to an / the element, device, component, part, step, etc. are to be construed openly as refer...

Abstract

A network node (30A, 30B) is configured for use in a wireless communication network (10). The network node (30A, 30B) is configured to acquire radio access capability information (28) of a wireless device (14). The radio access capability information (28) of the wireless device (14) indicates radio access capabilities of the wireless device (14). The network node (30A, 30B) is configured to determine if the wireless communication network (10) received the radio access capability information (28) of the wireless device (14) before access stratum security (24) was activated for the wireless device (14). If the wireless communication network (10) received the radio access capability information (28) of the wireless device (14) before access stratum security (24) was activated for the wireless device (14) according to that determination, the network node (30A, 30B) is configured to re-acquire the radio access capability information (28) of the wireless device (14) after access stratum security (24) is activated for the wireless device (14).

Description

technical field [0001] The present application relates generally to wireless communications, and more particularly to radio access capabilities of wireless devices. Background technique [0002] The wireless device notifies the wireless communication network of the device's capabilities when attached to the network and / or at other times, so that the device and network can communicate using parameters within the device's capabilities. The capabilities of a device can be classified into two categories, depending on which layer of the protocol hierarchy the capability relates to. Access stratum (AS) level capabilities are access technology dependent parts of capability information, such as device power class and supported frequency bands. AS capabilities are used by the radio access network. Therefore, AS capabilities may also be properly referred to as radio access capabilities. Non-Access Stratum (NAS) level capabilities are access-independent capabilities, such as support...
