Abstract
Protocol Data Unit (PDU) sessions in a communication network (10) provide logical interconnections between Data Networks (DNs) (16) and respective User Equipments (UEs) (12) that access the DNs (16) via the communication network (10), and the communication network (10) establishes one or more affiliated sessions in conjunction with each PDU session, such as an affiliated charging or policy control session. Rather than requiring the high signaling overhead associated with mass terminations of these affiliated sessions on a per session basis, the Network Functions (NFs) (32, 34, 36) contemplated herein provide for batch termination of a potentially large plurality affiliated sessions, based on the exchange of a corresponding batch termination message. Disclosed batch termination techniques include the exchange of information during session establishment, for later determination of which affiliated sessions are subject to batch termination.
