Method for dual-mode terminal to transmit and receive high speed packet data service information

Abstract

A method for using dual-mode 1X / DO terminal to send and receive high-speed grouped data service HRPD message comprises that a 1X / DO terminal residential in a code division multiple access CDMA 2000 1X network sends a HRPD message, setting a message packed with the object HRPD message, sending the set message to the CDMA 2000 1X network or an independent logic network unit which analyzes received message to obtain a HRPD message to be sent to the HRPD network, and when the 1X / DO terminal residential in a code division multiple access CDMA 2000 1X network receives the HRPD message, the CDMA 2000 1X network or independent logic network unit packs the HRPD message at HRPD network into the set message to be sent to the 1X / DO terminal via an idle port of the CDMA 2000 1X network. The invention can send and receive HRPD message in CDMA 2000 1X network, with confirmed transmission time delay and transmission safety.

Description

technical field [0001] The present invention relates to a method for transmitting messages in a Code Division Multiple Access (CDMA) 2000 1X network, in particular to a dual-mode (1X / DO) terminal in a CDMA 2000 1X network for sending and receiving High Speed ​​Packet Data Service (HRPD) messages Methods. Background technique [0002] Code Division Multiple Access (CDMA) 2000 network can include four phases of IS95, CDMA2000 1X, HRPD and 1Xev-DV, wherein HRPD network is a high-speed packet data network and cannot transmit circuit domain voice services. Therefore, in current practical applications, the HRPD network is used in conjunction with the CDMA2000 1X network. Using the characteristics of the HRPD network that can transmit high-speed packet services, it serves as a supplement to the CDMA2000 1X network for transmitting data services, thereby providing terminals with circuit domain voice services and packet data. business services. [0003] When HRPD network and CDMA20...

Because this process is just to carry out the encapsulation of CDMA2000 1X message to the small data packet such as short message from HRPD network, and adopt burst mode to transmit after the small data packet such as short message is encapsulated into the traffic channel that has already been established, to transmission time Neither delay nor transmission security is guaranteed. Therefore, it is not suitable for the encapsulation and transmission of signaling from HRPD networks that require high transmission delay and transmission security, such as paging messages, in CDMA2000 1X networks.
