Methods and systems for group re-authentication of devices in a wireless telecommunication network are provided. According to one aspect, a method of operation of a base station in a wireless telecommunication network comprises receiving a group authentication request message from a mobility management entity, the group authentication request message comprising a group identifier; identifying at least one user equipment as belonging to a group identified by the group identifier; sending an individual authentication request message to each identified UE; receiving an authentication response from at least one of the identified UE; aggregating the received at least one authentication response to create a group authentication response message; and sending the group authentication response message to the mobility management entity.

Enhanced aggregated re-authentication for wireless devices

Systems and methods relating to an efficient communication system to, e.g., support Massive Machine Type Communication (M-MTC) devices are disclosed. In some embodiments, a base station in a cellular communications network comprises, during initial attachment of a wireless device, establishing a Data Radio Bearer (DRB) between the base station and the wireless device, updating a context of the wireless device to include information regarding the DRB established between the base station and the wireless device to thereby provide a mapping between the DRB and a cellular network identifier of the wireless device. The method further comprises, during initial attachment of the wireless device, providing, to the wireless device, at least a portion of an Internet Protocol (IP) address assigned to the wireless device and updating the context of the wireless device to include the at least a portion of the IP address of the wireless device.

Simplified wireless connectivity for a cellular communications system

Systems and methods relating to scheduling Paging Occasions (POs) are disclosed. Embodiments of a method of operation of a network node are disclosed. In some embodiments, the method of operation of a network nodes comprises assigning POs to a plurality of User Equipments (UEs) in accordance with one or more anti-affinity groups such that, for a defined time interval, POs within the defined time interval are assigned to UEs in a same anti-affinity group. The method further comprises notifying the plurality of UEs of the POs assigned to the UEs. In this manner, the expected maximum number of pages within the defined time interval is substantially reduced.

Paging for massive MTC

A method in a first content centric networking (CCN) access point of a CCN network of enabling seamless mobility of a mobile device is disclosed. The method includes detecting a handover initiation event that is an indication that a handover of the mobile device from the first CCN access point to a second CCN access point from a group of one or more CCN access points of the CCN network is initiated. In response to detecting the handover initiation event, the method continues with starting transmission, to the group of CCN access points, of one or more pending interests associated with the mobile device. The method further includes detecting a handover completion event, and stopping, in response to detecting the handover completion event, the transmission of the one or more pending interests associated with the mobile device.
