A network node is configured to initiate a first authentication and key establishment procedure with a machine to machine (M2M) device. The network node is configured to determine a key agreement between the network node and the M2M device using the first authentication and key establishment procedure. The network node is configured to initiate a second authentication and key establishment procedure with an M2M server. The network node is configured to receive a request from the M2M server for the key agreement to be used to communicate with the M2M device using the second authentication and key establishment procedure. The network node is configured to send the key agreement to the M2M server using the second authentication and key establishment procedure.

Interface of an M2M server with the 3GPP core network

Systems, methods, and instrumentalities are provided to determine routing associated with a short message. A SMS-SC may send a first routing request to a home subscriber server (HSS). The first routing request may be associated with the short message. The SMS-SC may receive a first routing reply. The first routing reply may include one of an indication that the short message is associated with a service capability server (SCS) or a first control plane routing associated with the short message. The SMS-SC may send the short message to an SCS serving node. The first routing reply may include the indication that the short message is associated with a service capability server (SCS). The SMS-SC may send a second routing request to a SCS subscription database. The SMS-SC may receive a second routing reply from the SCS subscription database, which may indicate a second control plane routing for the short message.

Service capability server (SCS) terminated short message service (SMS) systems and methods

Disclosed herein are methods and devices for sharing a packet data protocol (PDP) context among a plurality of devices. For example, a method or sharing a PDP context among a plurality of devices may include a wireless transmit/receive unit (WTRU) sending a request to establish or modify a PDP context. The request to establish or modify the PDP context may include an indication that the WTRU is a member of shared context group. The method may also include the WTRU receiving a response indicating that the request to establish or modify the PDP context was accepted. The method may also include the WTRU acting as a gateway for at least one other device in the shared context group. The request to establish or modify the PDP context may be an attach request. The indication that the WTRU is a member of shared context group may be a group identifier (ID).

System and method for sharing a common PDP context

An M2M Server may be integrated into a 3GPP network. A network node, for example a Serving General Packet Radio Service (GPRS) Support Node (SGSN) may include a dedicated interface with a M2M server. The interface may be called a GM2M interface. The interface may be a logical interface internal to the network node. The node may receive subscriber data and control data, wherein the control data facilitates a network control procedure and the subscriber data identifies a device involved in the network control procedure. The node may determine that the device involved in the network control procedure is a machine to machine device based on the subscriber data. The node may also send the control data to a machine to machine server using a message sent via a dedicated interface with the machine to machine server.
