Network equipment implements a network function in a wireless communication network. The network equipment obtains integrity verification information that is a function of only a portion of a message. The message is either a request for a service to be consumed by the network function or a response to a request for a service provided by the network function. The network equipment digitally signs an assertion that includes the integrity verification information, and then sends the message and the digitally signed assertion to a service communication proxy. Other network equipment that receives the message and the digitally signed assertion may check an integrity of the portion of the message, based on integrity verification information that the other network equipment obtains and on the integrity verification information included in the digitally signed assertion.

Integrity verification in a wireless communication network

The invention relates to a method for a data consumer network function, NF, of a communication network to collect data from a data producer NF, the method comprising: ∘sending (), to a network repository function, NRF, in the communication network, a request for an access token for a service provided by a data collection coordination function, DCCF, in the communication network; ∘receiving (), from the NRF, at least one access token for the service provided by the DCCF; and ∘using () the at least one access token, collecting data from the data producer NF in the communication network via the DCCF service.
