Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. In one embodiment, The UE requests to switch the DL multicast traffic from the multicast MBMS bearer to the unicast EPS bearer upon detecting that the UE is approaching an MBMS coverage boundary. In another embodiment, the UE transmits an indication of preferred target cells to the network before performing a handover and thereby maintaining multicast service continuity of the group communication.

Abstract: A method of managing bandwidth resources provided by multiple network interfaces is proposed. When one or more network interfaces provide network bandwidth resources, a bandwidth manager manages all available bandwidth resources based on a list of decision criteria. The list of decision criteria includes energy efficiency, network throughput, channel condition, device mobility, and user preference. An application traffic flow distributer dynamically adjusts the amount of traffic flows on different network interfaces according to the joint decision based on the decision criteria. A network interface manager dynamically enables or disables each network interface according to the joint decision based on the decision criteria. Furthermore, a device movement analyzer analyzes and predicts device movement to facilitate accurate decision making of the bandwidth management.

Abstract: A method of enhanced session management procedure is proposed. A user equipment, upon receiving a rejected PDN connectivity request with a cause code, automatically alters the rejected factor to fit network restrictions based on the received cause code. The UE then retries the PDN connectivity procedure by sending a subsequent PDN connectivity request using the altered factor. By automatically altering the rejected factor and reattempting to establish an EPS bearer for data service without user interaction, possible permanent rejection can be avoided in case of user error or unawareness.
