DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
1. This is in response to communication filed on 9/06/24 in which claims 1-20 are pending.
Claim Rejections - 35 USC § 102
2. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
3. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Publication No. 2020/0259896 to Sachs et al.

b. As per claim 7, Sachs et al teaches a network node comprising: wherein the stream information includes at least one stream indicator each indicating a stream associated with Extended Reality (XR) traffic (See paragraph [0717, 1347], An identifier for the data stream may be established to enable it to be distinguished from other data streams), and the PDU set integrated packet handling information includes an indication for PDU set integrated packet handling associated with each stream indicator (See paragraph [1347], the identifier may be unique within the PDU session); and handle each stream indicated by at least one stream indicator contained in the stream information according to the indication for PDU set integrated packet handling associated with the stream indicator indicating the stream (See paragraph [1322 and 1329], An identifier might be added to data packets inside of PDU sessions or QoS Flows to differentiate multiple TSN/Ethernet streams within the same session or flow (thus the identifier is for a particular TSN/Ethernet stream). For example, the identifier may be used instead of the Ethernet header fields removed statically for transmission; an 8-bit header might be sufficient to separate TSN streams inside sessions or flows).
c. As per claim 12, Sachs et al teaches a method performed by a session management function (SMF) (See paragraph [1241 and 2192]) , the method comprising: constructing, for a specific user equipment (UE) or Protocol Data Unit (PDU) session, stream information and PDU set integrated packet handling information (See paragraph [1255, 1299. 2349 and 2385]), wherein the stream information includes at least one stream indicator each indicating a stream associated with Extended Reality (XR) traffic (See paragraph [0717and 1347] and Table 2 ( Augmented Reality) , An identifier for the data stream may be established to enable it to be distinguished from other data streams), and the PDU set integrated packet handling information includes an indication for PDU set integrated packet handling associated with each stream indicator (See paragraph [1347], the identifier may be unique within the PDU session); and transmitting the constructed stream information and PDU set integrated packet handling information to a User Plane Function (UPF) or Radio Access Network (RAN) node (See paragraph [1241], a UE can communicate data packets to a device and/or application on an external network (e.g., the Internet) by sending them via a serving gNB to a user plane function (UPF)).
d. As per claim 17, Sachs et al teaches a method performed by a network node, comprising: receiving, from a session management function (SMF) (See paragraph [1241 and 2192]), for a specific user equipment (UE) and Protocol Data Unit (PDU) session , stream information and an associated PDU set integrated packet handling information (See paragraph [1255, 1299, 2349 and 2385]), wherein the stream information includes at least one stream indicator each indicating a stream associated with Extended Reality (XR) traffic (See paragraph [0717and 1347] and Table 2 ( Augmented Reality) , An identifier for the data stream may be established to enable it to be distinguished from other data streams), and the PDU set integrated packet handling information includes an indication for PDU set integrated packet handling associated with each stream indicator (See paragraph [1347], the identifier may be unique within the PDU session); and handling each stream indicated by at least one stream indicator contained in the stream information according to the indication for PDU set integrated packet handling associated with the stream indicator indicating the stream (See paragraph [1322 and 1329], An identifier might be added to data packets inside of PDU sessions or QoS Flows to differentiate multiple TSN/Ethernet streams within the same session or flow (thus the identifier is for a particular TSN/Ethernet stream). For example, the identifier may be used instead of the Ethernet header fields removed statically for transmission; an 8-bit header might be sufficient to separate TSN streams inside sessions or flows).
e. As per claims 2 and 13, Sachs et al teaches the claimed invention as described above.
