7、perty rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR. When IPR consisting of patents and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof
8、 is requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire into, the scope or validity of any claims of IPR. TIA will neither be a party to discussions of any licensing terms or conditions, which are instead left

For an MS/AT h
46、aving a dual transmitter, refer to WiMAX 1.5 28. 1.1 Feature Descriptions This specification explicitly supports the following features: 1. Active handoff from WiMAX to HRPD for a single transmitter MS/AT. 2. Active handoff from HRPD to WiMAX for a single transmitter MS/AT. 3. Idle state handoff fro
47、m WiMAX to HRPD for a single transmitter MS/AT. 4. Idle state handoff from HRPD to WiMAX for a single transmitter MS/AT. 5. Client Mobile Internet Protocol version 4 (CMIPv4) on the WiMAX network. 6. Proxy Mobile Internet Protocol version 4 (PMIPv4) on the WiMAX network. 7. PMIPv6 on the WiMAX netwo
48、rk. 8. CMIPv4 on the HRPD network. 9. PMIPv4 on the HPRD network. 10. PMIPv6 on the HPRD network. 1.1.1 Active handoff from WiMAX to HRPD for a single transmitter MS/AT This feature supports the ability for an MS/AT operating with one active transmitter and one or more receivers to be seamlessly han
49、ded off from the WiMAX network to the HRPD network while the MS/AT is engaged in one or more active sessions. For this feature, roaming scenarios are not specified. The requirements for this feature are specified in this document. 1“WiMAX Forum,” the WiMAX Forum logo and the WiMAX Forum Certified logo are registered trademarks of the WiMAX Forum. “WiMAX,” “Mobile WiMAX,” “Fixed WiMAX,” “WiMAX Certified,” and “WiMAX Forum Certified” are trademarks of the WiMAX Forum. 3GPP2 X.S0058-0 v2.0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
