Identifiers and triggers for capillary devices
Methods and apparatuses for capillary network device registration implemented in a wireless transmit/receive unit (WTRU) are disclosed. Registration or bootstrap messages may be received by a capillary network device where the WTRU acts as a gateway for communication between the capillary device and a network such as a 3GPP network. A capillary network device identifier (CNDID) is sent to the capillary device. A packet data protocol (PDP) context or PDN connection may be established with the network and the CNDID may be sent to a machine type communications (MTC) server. The WTRU may create the registration message, establish a connection with the network, and forward the registration message to the MTC server. Methods and apparatuses implemented in a network are also disclosed for identifying, addressing, and triggering the capillary devices from the MTC server. The trigger message may include fields for group communication, reducing signaling, and enabling charging.
1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
receiving a first registration message comprising a capillary network device identifier (CNDID) from an application running on a capillary network device;
transmitting a second registration message including the CNDID to a core network;
establishing a packet data connection, comprising receiving an assigned identifier for the capillary network device, with the core network;
receiving a data message from the capillary network device; and
transmitting the data message, using the assigned identifier, to the core network.
2. The method of claim 1 , wherein the CNDID is transmitted to a machine type communications (MTC) server via a cellular radio access network (RAN).
3. The method of claim 1 , wherein the CNDID is formed by adding a field to an external device identifier of the WTRU.
4. The method of claim 1 , wherein the assigned identifier comprises an Internet protocol (IP) address for the core network.
5. The method of claim 1 , wherein the first registration message comprises an indication that the capillary network device is third generation partnership project (3GPP) radio access technology (RAT) capable.
6. The method of claim 1 , wherein second registration message comprises one or more selected from a 3GPP RAT capability indication, a capillary network device capability indication, an intended functionality, a location, an operation time, a duty cycle, and a manufacturer.
7. A wireless transmit/receive unit (WTRU) comprising:
a first receiver configured to receive, via an antenna, a first registration message comprising a capillary network device identifier (CNDID) from an application on a capillary network device;
a first transmitter configured to transmit, via an antenna, a second registration message, with the CNDID, to a core network;
a second receiver configured to establish a packet data connection comprising receiving an assigned identifier for the capillary network device, with the core network;
the first receiver further configured to receive a data message from the capillary network device; and
the first transmitter further configured to transmit the data message, using the assigned identifier, to the core network.
8. The WTRU of claim 7 , wherein the CNDID is transmitted to a machine type communications (MTC) server via a cellular radio access network (RAN).
9. The WTRU of claim 7 , wherein the CNDID is formed by adding a field to an external device identifier of the WTRU.
10. The WTRU of claim 7 , wherein the assigned identifier comprises an internet protocol (IP) address for the core network.
11. The WTRU of claim 7 , wherein the first registration message comprises an indication that the capillary network device is 3GPP RAT capable.
12. The WTRU of claim 7 , wherein second registration message comprises one or more selected from a 3GPP RAT capability indication, a capillary network device capability indication, an intended functionality, a location, an operation time, a duty cycle, and a manufacturer.
