標題: | Mobile Internet Telephony: Mobile Extensions to H.323 | 作者: | WANJIUN LIAO | 關鍵字: | H.323; Intemet telephony; Mobile extensions to H.323; Mobile intemet telephony; Voice over IP | 公開日期: | 三月-1999 | 卷: | 1 | 起(迄)頁: | 12-19 | 來源出版物: | Proceedings - IEEE INFOCOM | 摘要: | Intemet telephony realizes the transmission of twoway and real-time traffic over IP-based networks. The dominant standard for Intemet telephony is ITU-T Rec. H.323. With the current version of H.323, Internet telephony allows interoperability with circuit-switched telephone, but IP host mobility is not supported. In this paper, mobile extensions to H.323 that enable mobile Intemet telephony service are proposed. The proposed approach combines the characteristics of both cellular phone system and mobile IP mechanism with Intemet telephony, and therefore realizes the transmission of real-time voice traffic for both stationary and mobile hosts over IP-based networks. The most striking feature of the proposed approach is that the complicated mobility management functions are handled by the procedures for dynamically joining and departing from a conference, functions already defined in H.323. Therefore, our approach allows mobility support without the need for additional new entities, and with minimal modifications to existing H.323 standard. Such mobility extensions can serve as an add-on feature for the existing Intemet telephony systems compliant to the H.323 standard. © 1999 IEEE. |
