Abstract: Various communication systems may benefit from an identifier that can correlate a user equipment or a packet data network connection with a particular cell. For example, a correlation identifier may be useful to address management of user plane congestion and other use cases. A method can include generating a correlation identifier for a user equipment and/or a packet data network connection. The method also includes the ability to identify the user context information with the same correlation ID in the core network and in the radio access network. The method can also include sending the correlation identifier to a network element.

Abstract: Methods, apparatuses, and computer program products for enforcing time and usage limits are provided. One method includes allocating a usage allowance and time allowance for a group subscription to a network, and receiving a notification when a minimum threshold is reached for either the usage allowance or the time allowance within a certain duration. The method may further include determining a remainder of the usage allowance and a remainder of the time allowance by querying at least one policy and charging enforcement function, and reallocating the usage allowance and the time allowance based on the determined remainder of the usage allowance and the determined remainder of the time allowance.

Abstract: Systems, methods, apparatuses, and computer program products for providing IMS level awareness of high latency device are provided. One method, when a UE attaches to EPC, receiving, at a network node, an indication that the UE is a high latency device. The method may also include assigning, to the UE, an IP address selected from a special IP address range that is designated specifically for high latency devices. When the UE performs IMS registration, the method may include determining that the UE is a high latency UE based on the UE's IP address provided with the IMS registration request and assigned during the EPC attach procedure.
