A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-17 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over He et al., US 20240205775 A1 (hereinafter “He”) in view of Chockalingam et al., US 20160360462 (hereinafter “Chockalingam”).
Regarding Claim 1, He teaches a network handover method performed by an electronic device, the method comprising:
determining whether a set of event types includes at least one first event type in response to determining to hand over the electronic device from a first wireless network to a second wireless network, the set of event types including types of events to be reported to a first base station by the electronic device, the at least one first event type being associated with network handover for the electronic device (He, Pages 11-12, Paragraphs 147-150, Fig. 18, terminal 1810, base station 1820-1, 1820-2, handover may be performed by adjusting a threshold under condition that QoS is maintained, measurement report trigger threshold [MRTTHD]; Page 13, Paragraphs 161-162, Fig. 21, S2101, terminal receives information related to threshold of signal strength for triggering measurement report), the electronic device being connected to the first base station through a radio resource control connection (He, Page 5, Paragraph 72, RRC), the first base station corresponding to the first wireless network, and a second base station corresponding to the second wireless network being detected by the electronic device (He discloses handover from a first base station to second base station but does not specify each base station corresponding to a respective wireless network, Pages 11-12, Paragraphs 149-150, Fig. 18, terminal 1810, first base station 1820-1, second base station 1820-2);
determining whether a measurement signal measured by the electronic device is capable of triggering a first event of the at least one first event type in response to determining that the set of event types includes the at least one first event type, the measurement signal of the electronic device indicating one of,
both a signal of the first wireless network and a signal of the second wireless network, or the signal of the second wireless network (He, Page 12, Paragraph 150-154, Fig. 19, threshold of signal strength for handover initiation may be adjusted according to a type of events to which threshold is applied);
modifying the measurement signal to obtain a first modified measurement signal in response to determining that the measurement signal is not capable of triggering the first event, the first modified measurement signal being capable of triggering the first event (He, Page 13, Paragraph 158, MRTTHD adjustment value may be selected by terminal); and
transmitting a first measurement report to the first base station, the first measurement report being based on the first modified measurement signal (He, Pages 13-14, Paragraph 163, Fig. 21, S2103, transmit measurement report to base station based on information related to threshold).
He fails to fully teach the limitation:
the first base station corresponding to the first wireless network, and a second base station corresponding to the second wireless network being detected by the electronic device
However, Chockalingam further teaches the limitation:
the first base station corresponding to the first wireless network, and a second base station corresponding to the second wireless network being detected by the electronic device (Chockalingam, Page 5, Paragraphs 32-33, heterogenous wireless communication system)
Although He addresses the remaining limitations of claim 1, Chockalingam demonstrates the following limitations of a teaches a network handover method performed by an electronic device, the method comprising:
determining whether a set of event types includes at least one first event type in response to determining to hand over the electronic device from a first wireless network to a second wireless network, the set of event types including types of events to be reported to a first base station by the electronic device, the at least one first event type being associated with network handover for the electronic device (Chockalingam, Pages 7-8, Paragraphs 48-51, Fig. 5, UE 502, serving eNodeB 506, eNodeB of the neighbor cell 504; Table 1, measurement reporting events), the electronic device being connected to the first base station through a radio resource control connection, the first base station corresponding to the first wireless network, and a second base station corresponding to the second wireless network being detected by the electronic device (Chockalingam, Page 5, Paragraphs 32-33, heterogenous wireless communication system);
determining whether a measurement signal measured by the electronic device is capable of triggering a first event of the at least one first event type in response to determining that the set of event types includes the at least one first event type, the measurement signal of the electronic device indicating one of,
both a signal of the first wireless network and a signal of the second wireless network, or the signal of the second wireless network (Chockalingam, Page 7, Paragraph 50, measured metrics of serving eNodeB, neighbor base stations, identify breach of defined handover/reselection threshold[s]);
modifying the measurement signal to obtain a first modified measurement signal in response to determining that the measurement signal is not capable of triggering the first event, the first modified measurement signal being capable of triggering the first event (Chockalingam, Pages 8-9, Paragraphs 53-58, the wireless communication device modifies measurement report values to indicate that event condition[s] met); and
transmitting a first measurement report to the first base station, the first measurement report being based on the first modified measurement signal (Chockalingam, Page 9, Paragraph 56, measurement report reported to serving cell to trigger handover).
Chockalingam and He are considered to be analogous to the claimed invention because they are in the same field of controlling handoff arrangements. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have He to incorporate the teachings of Chockalingam for the first base station corresponding to the first wireless network, and a second base station corresponding to the second wireless network being detected by the electronic device. Doing so would broaden the capability of handover arrangements with consideration to network-defined thresholds in a heterogenous wireless communication system.
