The invention provides method and system for transmitting word information in the call-connection process of a CDMA (Code Division Multiple Access) network. The method comprises the following steps of: storing the mapping relationships of calling numbers and calling word information at a calling side; when sending call connection to called numbers by using the calling numbers, inquiring the calling word information corresponding to the calling numbers; sending an addressing request to a called side wherein the called numbers belong to, wherein the addressing request carries with the calling word information; inquiring routing information according to the addressing request, wherein the routing information includes the roaming numbers of the called numbers, returning the roaming numbers of the called numbers to the calling side and saving the calling word information; sending an initial calling request to the roaming numbers by using the calling side; and when receiving the initial calling request at the called side, issuing and displaying the calling word information. The invention can display the calling numbers and also display the word information defied by calling users in the call-connection process of the CDMA network.
