A telecommunications system and method is disclosed for load sharing within a CDMA2000 network. The queue size of a sector (or cell) is compared with a predefined threshold. If the queue size exceeds the predefined threshold, one or more mobile terminals having their Data Rate Control (DRC) pointed towards that sector are selected to discontinue using that sector. The network transmits a message to the selected mobile terminals informing the selected mobile terminals that their DRC is no longer valid. In response, the selected mobile terminals stop pointing their DRC towards that sector, which results in an interruption of the selected mobile terminal's data sessions. To continue their data sessions, each of the selected mobile terminals may initiate a “virtual” handoff to another sector.

A Virtual Soft Handover (VSHO) process for high data rate (HDR) applications is disclosed that considers the total number packets remaining to be transmitted prior to initiating the VSHO. An HDR mobile terminal maintains data transmission information relating to an amount of data to be transmitted during a data transfer in progress during a data session. The data transmission information may include, for example, the total packet size of a data transmission and the data transmission status (i. e. , the number of packets remaining to be transmitted). The decision of whether to perform a VSHO is made according to the data transmission information. In one embodiment, a VSHO may be deactivated when the number of packets remaining to be transmitted is less than a certain threshold. In other embodiments, a VSHO may not be performed if the total packet size is smaller than a certain threshold.

A telecommunications system and method is disclosed for delivering a Short Message Service (SMS) message to a dual mode mobile terminal in data mode within a network capable of providing both voice services and data services. To receive the SMS message during a data session, the SMS message is encapsulated into an Internet Protocol (IP) packet and routed to the mobile terminal as an electronic mail (e-mail) message. In one embodiment, when the SMS message is received at the Mobile Services Switching Center (MSC) serving the mobile terminal, the MSC determines whether the mobile terminal is in data mode. If so, the MSC converts the SMS message into an email message and routes the e-mail message to the mobile terminal via the Packet Data Service Node (PDSN) serving the mobile terminal. In an alternative embodiment, the MSC routes the SMS message to the Base Station Controller (BSC) serving the mobile terminal. The BSC translates the SMS message into an e-mail message and transmits the e-mail message to the mobile terminal.
