5G delay tolerant data services
Methods and apparatuses are described herein for a 5G system that deploys services providing optimizations and value add services based on delay tolerant data (DTD) exchanges between end devices and machine to machine (M2M) servers. In accordance with one embodiment, an apparatus may receive, from a second apparatus via the network, first information comprising a delay tolerant communication configuration comprising an identifier and a delay tolerant characteristic. The apparatus may receive, from a third apparatus, data in a plurality of data bundles that each comprises the identifier. The apparatus may process, based on the first information, the plurality of data bundles. The apparatus may route, based on the first information, the plurality of data bundles. The third apparatus may comprise a user equipment (UE).

receive, from a first apparatus, configuration information indicating an identifier and a delay tolerant characteristic, wherein the identifier indicates delay tolerant traffic;
receive, from a second apparatus, one or more packet data unit (PDUs), wherein each PDU, of the one or more PDUs, is associated with the identifier;
buffer, based on the configuration information, the one or more PDUs; and
send, based on the configuration information, the one or more PDUs.
2. The WTRU of claim 1 , wherein the first apparatus comprises at least one of: a server, a network function, or a user equipment (UE).
3. The WTRU of claim 1 , wherein the configuration information comprises at least one of: a type of endpoint for delay tolerant communication, an identity of an endpoint for delay tolerant communication, a delay tolerant data (DTD) information type, optimization services requested from a core network (CN), data path constraints, or communication scheduling information.
4. The WTRU of claim 1 , wherein the second apparatus comprises a user equipment (UE).
5. The WTRU of claim 1 , further configured to:
send, to a user equipment (UE), second information to configure delay tolerant communications between the UE and a third apparatus, wherein the third apparatus comprises a remote device.
6. The WTRU of claim 1 , further configured to:
remove duplicate PDUs from the one or more PDUs.
7. The WTRU of claim 1 , wherein the buffering aggregates the one or more PDUs into a data bundle.
8. The WTRU of claim 1 , wherein the sending comprises identification of alternate downlink data paths.
9. The WTRU of claim 8 , wherein the identification of alternate downlink data paths is based on one or more of: network resources, estimated endpoint trajectory, geographical information, communication scheduling, delay tolerant data (DTD) information type, or DTD capabilities.
10. The WTRU of claim 9 , wherein the sending comprises transmission or retransmission of downlink PDUs of the one or more PDUs via the alternate downlink data paths identified.
11. The WTRU of claim 1 , further configured to:
send, to a third apparatus, second information to configure delay tolerant communications between the third apparatus and a remote device; and
send, to the third apparatus, a request to page the remote device, wherein the request comprises a device identifier, a direct communication type, delay tolerance parameters, response notification types, a response aggregation type, and a paging payload.
12. The WTRU of claim 1 , further configured to:
send, to a third apparatus, second information to configure delay tolerant communications, comprising delay tolerant group broadcast or multicast services, between a user equipment (UE) and a remote device, wherein the UE is configured to monitor multicast communications based on communication identifiers, delay tolerance parameters and geographical information and wherein the UE is configured to route the multicast communications based on the second information.
13. The WTRU of claim 1 , further configured to:
determine an identity of a user equipment (UE) that is likely to receive a PDU of the one or more PDUs that has already been received; and
send, to the UE, an indication that the PDU has been already received.
14. The WTRU of claim 1 , further configured to:
send, to the first apparatus, a partial acknowledgement; and
send, to the first apparatus, an end-to-end acknowledgement.
15. A method for use in a wireless transmit/receive unit (WTRU) comprising a transceiver and one or more processors, the method comprising:
receiving, from a first apparatus, configuration information indicating an identifier and a delay tolerant characteristic, wherein the identifier indicates delay tolerant traffic;
receiving, from a second apparatus, one or more packet data unit (PDUs), wherein each PDU, of the one or more PDUs, is associated with the identifier;
buffering, based on the configuration information, the one or more PDUs; and
sending, based on the configuration information, the one or more PDUs.
16. The method of claim 15 , wherein the first apparatus comprises at least one of: a server, a network function, or a user equipment (UE).
17. The method of claim 15 , wherein the configuration information comprises at least one of: a type of endpoint for delay tolerant communication, an identity of an endpoint for delay tolerant communication, a delay tolerant data (DTD) information type, optimization services requested from a core network (CN), data path constraints, or communication scheduling information.
18. The method of claim 15 , wherein the second apparatus comprises a user equipment (UE).
19. The method of claim 15 , further comprising:
removing duplicate PDUs from the one or more PDUs, or
buffering of data bundles of the plurality of data bundles to enable aggregation of data bundles.
20. The method of claim 15 , wherein the buffering aggregates the one or more PDUs into a data bundle.
