NAPPI, TERRENCE W. McMILLIN, and JOHN A. HUDALLA, Administrative Patent Judges. NAPPI, Administrative Patent Judge. DECISION ON APPEAL Appellant appeals under 35 U.S.C. § 134(a) from the Examiner's final rejection of claims 1 through 19. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm. INVENTION The invention is directed to efficiently configuring quality of service (QoS) and radio resources for a call in a wireless network. Abstract. Claim 1 is representative of the invention and is reproduced below. 1. An apparatus, comprising: at least one processor configured to detect one or more access points in a wireless local area network (WLAN), to 1 According to Appellant, QUALCOMM Inc. is the real party in interest. App. Br. 3. Appeal2018-004997 Application 12/788,495 determine whether any detected access point is suitable for receiving service, to perform service registration with a suitable access point in the WLAN, wherein the service registration is for only one or more certain services depending on performance of the access point and Quality of Service (QoS) requirements of the one or more services, and to establish a communication call that is supported by the one or more services associated with the service registration; and a memory coupled to the at least one processor. EXAMINER'S REJECTI0NS 2 The Examiner has rejected claims 1, 8, 11, 14, 17, and 19 under 35 U.S.C. § 103 as unpatentable over Hsu et al. (US 2004/0165563 Al, published Aug. 26, 2004) and Curcio et al.

(US 2005/0007984 Al, published Jan. 13, 2005). Final Act. 18. ANALYSIS We have reviewed Appellant's arguments in the Brief, the Examiner's rejection, and the Examiner's response to Appellant's arguments. Appellant's arguments have not persuaded us of error in the Examiner's obviousness rejection of independent claim 1. Appellant argues that the Examiner's rejection of independent claim 1 under 35 U.S.C. § 103 is in error because: a) the Examiner has not provided a reasonable basis for combining Hsu, and Curcio, and b) the combined teaching of Hsu and Curcio do no teach or make obvious performing the quality of service registration with an access point as recited in representative claim 1. App. Br. 5-12. With respect to the first issue, Appellant argues the Examiner has not established a reasonable basis for combining Hsu and Curcio such that Curcio's teachings of requesting different QoS for each Packet Data Protocol (PDP) context into Hsu's teaching of handing over a packet data session to a WLAN. App. Br. 5. Appellant argues that "the Examiner has not established that QoS is available on WLAN s at all, let alone tiered QoS that would be comparable to the tiered QoS that can be obtained via different PDP context configurations in the UMTS network of Curcio." App. Br. 7. Further, Appellant argues that the PDP contexts of Curcio are used in a cellular universal mobile telephone system (UMTS) infrastructure and that: [E]ven if UMTS networks and WLAN s share the common characteristic of being able to connect to IP networks, UMTS networks and WLAN s also include fundamental differences in 3 Appeal2018-004997 Application 12/788,495 terms of their respective network infrastructures and how/whether QoS is used to support connections. The mere fact that UMTS networks can provide tiered QoS levels via PDP context parameter configurations does not make it obvious to apply these same QoS protocols to WLAN s. App. Br. 8. The Examiner provides a comprehensive response to Appellant's arguments on pages 3 through 15 of the Answer. We have reviewed the Examiner's response and the cited teachings of Hsu and Curcio and we concur with the Examiner's findings and rationale. Specifically, we concur with the Examiner's finding that Hsu teaches WLANs are used by cellular carriers to alleviate loading of the cellular system. Answer 3 ( citing Hsu para. 7). Further, we concur with the Examiner's finding that: Hsu also discloses ([0073] [t]he cellular network may then instruct the MS 702 to switch to the WLAN. The decision to switch from the cellular network 706 to the WLAN is based on loading of the network, bandwidth of the user, data requirements, etc.), hence the cellular network includes both CDMA and GSM-UMTS. And Curcio discloses ([0120] In the request the wireless communication device MTl includes the wanted QoS parameters (maximum bit rate of 70 kbps) for all the media components). That is, as the wireless communication device requests a PDP context (i.e., application/service with a certain QoS, it requests a service for only one or more certain services depending on performance of the access point and Quality of Service (QoS) requirements. Like Hsu, Curcio discloses in Figure 1 an integrated telecommunication system comprises of cellular network and WLAN such as IP network 7. Hence a skilled artisan would "be able to fit the teachings of multiple patents together like pieces of a puzzle" since the skilled artisan is "a person of ordinary creativity, not an automaton." Answer 5. Appellant's Specification states "WLAN 100 may also 4 Appeal2018-004997 Application 12/788,495 implement IEEE 802 .11 e, which covers QoS enhancements for a Medium Access Control (MAC) layer;" thus acknowledging that the IEE 802 .11 e WLAN protocol does use QoS enhancements. See Specification para. 26. As such we are not persuaded by Appellant's arguments, which are premised upon the assertion that the Examiner has not shown QoS requirements are used in WLAN systems. We are similarly not persuaded by Appellant's augment that Hsu's teaching of handling voice calls after handoff shows that the WLAN cannot provide the same QoS as the cell network. Reply Br. 2 ( citing Hsu para. 86). The cited passage of Hsu does not discuss voice calls as being of high priority or as requiring high QoS or that the reason they remain on cellular is for that reason; rather, the paragraph discusses a power save feature where even after handover to the LAN the mobile station is monitoring for paging and may receive voice calls on the cellular channels. Thus, Appellant's arguments have not persuaded us of error in the Examiner's rationale in combining the teachings of Hsu and Curcio. With respect to the second issue, Appellant argues the combined teaching of Hsu and Curcio does not teach or make obvious performing the quality of service registration with an access point. App. Br. 11. Specifically, Appellant argues: In such a combination, the Appellant believes that the WLAN APs would participate in QoS procedures similarly to the UMTS BSs in Curcio. In other words, QoS is reserved by a higher-level network entity analogous to the SGSN/GGSN in UMTS, and the WLAN APs do their part to support the reserved QoS level (similar to the UMTS BSs in Curcio). There would be no particular reason as to why the services requested from a particular WLAN AP would be restricted to "only one or more certain services" based on QoS requirements of those service(s), because the WLAN APs even in this 5 Appeal2018-004997 Application 12/788,495 hypothetical combination of Hsu and Curcio would not be distinguished from each other based on their QoS capacity. App Br. 11. The Examiner responds on pages 15 through 18 of the Answer. The Examiner Hsu teaches that the mobile device registers with the WLAN access point based upon bandwidth and data requirements. Answer 15-16 ( citing Hsu para. 85). When combined with Curcio's teaching that different PDP contexts have different QoS requirements, the mobile station would register with a suitable WLAN access point based upon the QoS requirements. Answer 16. We concur with the Examiner and are not persuaded of error by Appellant's arguments. Representative claim 1 recites determining whether the detected access point is suitable and performing service registration with a suitable access point ... depending on the performance of the access point and the QoS requirements of the services. Thus, Appellant's argument above is not commensurate with the scope of the claim as it does not recite where the QoS registered. Accordingly, we are not persuaded of error by Appellant's arguments directed to the second lSSUe. The above two issues are the only issues raised by Appellant's arguments with respect to representative claim 1. As we are not persuaded of error by Appellant's arguments with respect to these issues, we sustain the Examiner's rejection of representative claim 1, and claims 8, 11, 14, 17, and 19 grouped with claim 1 and similarly rejected under 35 U.S.C. § 103 as unpatentable over Hsu and Curcio. Appellant has not presented separate arguments with respect to the rejections of dependent claims 2 through 7, 9, 10, 12, 13, 15, 16, and 18. 6 Appeal2018-004997 Application 12/788,495 Accordingly, we sustain the Examiner's rejection of these claims for the reasons discussed with respect to independent claims 1. DECISION We affirm the Examiner's rejections of claims 1 through 19 under 35 U.S.C. § 103. No time period for taking any subsequent action in connection with this appeal maybe extended under 37 C.F.R. § 1.136(a)(l)(iv) (2016). AFFIRMED 7 Copy with citationCopy as parenthetical citation
