Contextualized information bus

Data transmissions are scheduled from internet of things (IoT) user equipment (UEs) to a base station (BS) that serves those IoT UEs in a cellular network. A BS may broadcast synchronization information to the IoT UEs that allows the BS to calculate and use a schedule for receiving data transmissions from the UEs. This information can include a total number of the IoT UEs being serviced, a length of a spreading code to use in the schedule, a time domain periodicity of available resources, and a maximum number of the IoT UEs that can send data to the BS at one time. Each IoT UE can independently apply a mathematical operation to the broadcast information it receives to calculate and use the schedule. The BS can receive the data transmissions from each of the IoT UEs according to that schedule.

A method for pushing data in a Content-Centric Networking (CCN) network comprises receiving a message from a source at an input interface device of a node device in the CCN network, the node device executing a CCN protocol. A determination is made that the received message is an interest-notification message. The received message is identified as the interest-notification message by including a Type field, a Content Name field, and a Cacheable Object field. The Type field indicates that the received message is pushing data within the CCN network. The Content Name field associates a hierarchical name to the data being pushed within the CCN network. The Cacheable Object field includes a cacheable object representing the data being pushed within the CCN network. The cacheable object is extracted in response to the received message being an interest-notification message. The cacheable object is placed in a cache at the node device.

The method includes receiving an information-centric networking content-identifier (ICN-CID) from an application.

Enabling cross-layer receiver oriented dynamic multicast in cellular access

Technology for stateless forwarding of packets in an ICN is disclosed. Content routers modify a dynamic filter in an interest packet. In one aspect, a content router extracts a dynamic filter from an interest packet received on an ingress port and combines the dynamic filter with a local filter associated with the ingress port. The packet filter and the local filter may be combined without losing information in the packet filter or the local filter. A new filter may be inserted into the interest packet based on the combined packet filter and local filter. The interest packet having the new filter may be forwarded on an egress port. The data packet that returns the content object for the interest packet may be forwarded statelessly based on the dynamic filter. Thus, the data packet may be forwarded without use of a pending interest table (PIT).
