摘要： A service request is received at a first service communication proxy element, wherein the service request is received from a service consumer and is a request to access at least one service of a service producer. The first service communication proxy element determines at least one target service producer based on the service request. The first service communication proxy element sends an access token request to an authorization entity, wherein the access token request is generated based on the determining step. The first service communication proxy element receives an access token response from the authorization entity, wherein the access token response comprises an access token. The first service communication proxy element may then send a service request with the access token to a second service communication proxy element, wherein the second service communication proxy element is associated with the target service producer. The method may apply to roaming and non-roaming scenarios.

摘要： According to an example aspect of the present invention, there is provided an apparatus configured at least to determine whether a cryptographic signature of a token received in the apparatus from a network function consumer is valid, obtain a cryptographic signature of the apparatus of the token responsive to the cryptographic signature of the token being valid, and provide the token to a peer entity of the apparatus, wherein the cryptographic signature of the apparatus is either included into the token or provided in a header external to the token, wherein the peer entity is comprised in a second network, different from a first network where the apparatus is comprised in. The request may serve a user equipment, directly or indirectly.

摘要： A service request is received at a first service communication proxy element, wherein the service request is received from a service consumer and is a request to access at least one service of a service producer. The first service communication proxy element determines at least one target service producer based on the service request. The first service communication proxy element sends an access token request to an authorization entity, wherein the access token request is generated based on the determining step. The first service communication proxy element receives an access token response from the authorization entity, wherein the access token response comprises an access token. The first service communication proxy element may then send a service request with the access token to a second service communication proxy element, wherein the second service communication proxy element is associated with the target service producer. The method may apply to roaming and non-roaming scenarios.
