Abstract: Methods, apparatus and computer program products for binding information management. A method implemented at a policy control node in a wireless communication network comprises: obtaining information indicating a collocated deployment of a session management node and a binding support node (202); and inhibiting, in response to the information, a registration of binding information to the binding support node (204). A policy control node can know that a binding support node is collocated with a session management node, and no registration of binding information to the binding support node will be triggered for the policy control node.

Abstract: Methods and apparatuses are disclosed for network triggered service restoration (NTSR). According to an embodiment, a serving gateway (SGW) obtains, from a mobility management entity (MME), information capable of indicating whether to apply NTSR for a terminal device. In response to detecting a failure of the MME, the SGW determines whether to apply NTSR for the terminal device based on the obtained information.

Abstract: A method performed by a charging function entity comprises sending a charging notify request comprising at least one information element to a network function entity. The at least one information element is used for determining which quota and/or usage reporting is required to be updated to the charging function entity. The method further comprises receiving a charging notify response from the network function entity. When validation of a part of the at least one information element is failed, the charging notify response comprises a first status code and error information related to the part of the at least one information element.
