Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A network node capable of incrementally obtaining wireless device capability information, the network node comprising processing circuitry operable to:
receive a context setup request for a first wireless device from an access and mobility management function (AMF);
determine whether the context setup request includes device capability information relevant to the network node;
upon determining the context setup request does not include device capability information relevant to the base station:
transmit a first device capability enquiry to the first wireless device;
receive a user equipment (UE) model identifier (UE-ModelId) from the first wireless device, wherein the UE-ModelId identifies a set of device capabilities for all wireless devices that share the same UE-ModelId;
determine whether the network node has stored device capability information associated with the UE-ModelId that is relevant to the network node;
upon determining the network node does not have stored device capability information associated with the UE-ModelId relevant to the network node:
transmit a second device capability enquiry to the first wireless device, the second device capability enquiry including a capability filter that identifies capability information relevant to the network node;
receive a first subset of device capabilities identified by the first capability filter from the first wireless device; and
update stored device capability information associated with the UE-ModelId with the first subset of device capabilities.
