Abstract

The present disclosure proposes a Virtual Shared Mobile (VSM) feature at eNodeB level, relay node, ore UE or device level that will allow multiple MTC devices to be grouped together and be presented to the rest of Mobile Network as one Virtual Shared Mobile (VSM). The MTC Application Servers will authenticate and manage individual MTC devices. This will decrease the number of devices that are managed by the mobile network and hence decreasing the control signalling volume. Devices belonging to the same Virtual Shared Mobile Group (VSMG) will use time division to share the same Radio Bearer (same IMSI) and hence decreasing the interference to the other UEs in the mobile network. Overall the disclosure will allow data gathering from a large number of MTC devices with limited impact on the Mobile Network. Disclosed herein are aspects of the VSM concept, including inter alia: (1) the VSM implemented in the eNB; (2) the VSM implemented in a relay node; and (3) the VSM implemented in a UE or device acting as a relay node in a device-to-device configuration.

Claims

1. A machine-type-communication (MTC) virtual shared mobile (VSM) apparatus suitable for use in a communications network including a mobile network, the mobile network having wireless nodes including a wireless base station node and wireless device nodes, the wireless base station node serving the wireless device nodes, a portion of the wireless device nodes being a plurality of MTC devices, the communications network connected to at least one MTC application server, the MTC VSM apparatus comprising:

a node of the wireless device nodes in the communications network, comprising;

a communications interface for participating in at least one MTC related communication involving one of the at least one MTC application server and at least one of the plurality of MTC devices, an MTC device of the plurality of MTC devices that does not belong to a virtual shared mobile group (VSMG) utilizes a device identifier of the MTC device that does not belong to the VSMG in an initial connection request to join the VSMG and at least one of the plurality of MTC devices belongs to the VSMG having a VSMG identifier that permits sharing the same uplink and downlink physical resources; and

a processor configured to operate with the communications interface, the processor configured such that a portion of the at least one MTC related communication presents the plurality of MTC devices to the at least one MTC application server as one VSM wireless device having a single mobile subscriber identity such that the mobile network is unaware of the plurality of MTC devices, communications relating to each of the plurality of MTC devices being multiplexed over a single channel.

2. The MTC VSM apparatus of claim 1, wherein the node in the communications network is one of an:

7. The MTC VSM apparatus of claim 1, wherein the at least one of the plurality of MTC devices uses a mobile network identifier of the at least one of the plurality of MTC devices to send a VSM Transmission Time Interval (TTI) grant request message to the node in the communications network of the MTC VSM apparatus.

8. The MTC VSM apparatus of claim 1, wherein the portion of the at least one MTC related communication is encrypted at the application layer.

9. A machine-type-communication (MTC) virtual shared mobile (VSM) method suitable for use in a communications network including a mobile network, the mobile network having wireless nodes including a wireless base station node and wireless device nodes, the wireless base station node serving the wireless device nodes, a portion of the wireless device nodes being a plurality of MTC devices, the communications network connected to at least one MTC application server, the MTC VSM method comprising:
