Abstract: Systems and methods are provided for reserving resources in a telecommunication network. The method including: receiving, at a node, a first service request to reserve a quantity of resources from a subscriber's first account, wherein the quantity of resources requested to be reserved are greater than an amount of available resources in the subscriber's first account; determining, at the node, that the quantity of resources needed to be reserved is within an overbooking limit associated with the subscriber's first account; and reserving, based on the determining step, the requested quantity of resources.

Abstract: A method for implementing user defined policies in a communication network. In one aspect, a policy function (e.g., an online charging system (OCS)) receives a policy information request having a subscription identifier, SID, identifying a subscription where a set of two or more policies are linked to the SID, and one of the policies included in the set of policies is set as an active policy for the subscription, and where each policy is associated with a different user identifier, UID. The policy function determines the policy that is set as the active policy for the subscription identified by the SID included in the policy information request. Using the determined UID, the policy function obtains and transmits the active policy.

Abstract: A network node and method for enhancing message communication between a first network node and a second network node in a communication network is provided. The first network node receives an input message from the second network node wherein the input message contains at least one parameter. The first network node then identifies in the received input message the presence of the at least one parameter, wherein the parameter is unknown to the first network node. After identifying at least one unknown parameter, the first network node sends a request message to the second network node for obtaining meta-data associated with the identified unknown parameter. The first network node then receives a response message from the second network node containing the said obtained meta-data associated with the identified unknown parameter. After receiving the response message, the first network node updates the obtained meta-data associated with the unknown parameter.
