Abstract: Methods for managing device connectivity of machine type communications devices include receiving a packet data protocol based command addressed to a Machine Type Communication (MTC) device, determining if the MTC device has an active packet data protocol context, in response to determining that the MTC device does not have an active packet data protocol context, activating a packet data protocol context for the MTC device, and forwarding the packet data protocol based command to the MTC device.

Abstract: Example embodiments presented herein are directed towards providing direct communications between a mobility management node (e.g., SGSN, S4-SGSN or MME) and an MTC-IWF node via a T5 interface. With the use of the direct communications unnecessary queries to a HSS or HLR may be avoided. The direct communications are established by the mobility management node and the MTC-IWF node saving identifying information of the other node.

Abstract: There is provided mechanisms for communicating non-IP data over a PDN of PDN type IPv4, IPv6, or IPv4IPv6. A method is performed by a core network gateway node. The method comprises communicating IP packets over a packet data network of PDN type IPv4, IPv6, or IPv4IPv6 with an application server, the IP packets comprising an IP header and being addressed to a wireless device. The method comprises communicating header-less payload packets over the packet data network with the wireless device. The header-less payload packets correspond to the IP packets having the IP header removed and represent the non-IP data.

Abstract: A machine-to-machine communication proxy node is presented herein. The proxy node may be used as a translation device in machine-to-machine communications. For example, if an application server in a packet based network initiates communication with device in a mobile network, the proxy node may be utilized to translate application domain specific device identities coded in the format of Session Initiation Protocol (SIP) and Uniform Resource Identifier's (URI's) to mobile specific identities such as IMSI and establish communication connection in the mobile network. This identifying of mobile devices may be utilized to replace the commonly used E.164 Mobile Subscriber Integrated Services Digital Network (MSISDN) numbers for identifying mobile devices.

Abstract: Various embodiments described herein aim to ensure that user data transmissions (e.g., small data transmissions that are sent using control plane messages) do not become excessive and stay infrequent, thereby reducing the likelihood of a network overload situation. In one embodiment, an admission control function (ACF) for regulating the transmission of uplink user data is implemented in a wireless communication device (WCD) (e.g., a CIoT device). Such a WCD device may receive from a core serving node (CSN) admittance information (AI) (e.g., parameters, such as thresholds, used by the ACF to regulate the uplink traffic) that is used in performing the admittance control.

Abstract: For transmission of multicast data in a cellular network, a gateway (200) allocates a set of multicast sessions (111, 112) to a single Internet Protocol Multicast group (110). For each of the multicast sessions (111, 112), the gateway indicates an Internet Protocol Multicast address of the Internet Protocol Multicast group to one or more radio access network nodes (100) of the cellular network. For each of the multicast sessions (111, 112), the gateway (200) indicates a different identifier to the radio access network nodes (100), e.g., in the form of a Tunnel Endpoint Identifier. The gateway (200) sends multicast data of the multicast sessions (111, 112) in one or more Internet Protocol Multicast data packets addressed to the Internet Protocol Multicast address of the Internet Protocol Multicast group. The multicast data of each of the multicast sessions (111, 112) include the respective identifier to allow identification of the multicast session (111, 112) at the radio access network node (100).

Abstract: Methods and related systems for controlling congestion in a communication network are provided. The methods generally allow a network node to receive requests for transmission from user equipments, and to selectively, and generally temporarily, block certain requests for transmission if congestion has been determined to be associated with their destination addresses. The methods also generally allow user equipments to be notified of the rejection of their requests for transmission such as to refrain from immediately try to retransmit their requests. By controlling the transmission and processing of requests for transmission when their destination addresses are determined to be congested, congestion at these addresses can be at least mitigated.
