A method and system is provided for providing packet data service and circuit switch service during the same session to a mobile station (MS) whose capabilities do not allow such services to be provided thereon by the wireless network according to the its specifications. First, a voice service is provided between the MS and a first client through a switch device, the voice service conforming to a predetermined communication protocol. The MS is then notified about an incoming data service request from a second client to transfer a predetermined amount of data. The voice service is disconnected between the switch device and the MS if the user decides to activate the incoming data service. The voice service between the switch device and the first client is still maintained. The data service from the second client to the MS through the switch device is then established. The data service between the switch device and the MS is disconnected while the data service between the switch and the second client is maintained after the predetermined amount of data has been transferred from the second client to the MS.

A method and system is provided for routing at least one message from one or more subscribers of a communications network in a network node, the network node having a plurality of processing cards (Pcards). First, at least one Pcard is designated to service messages from a predetermined set of subscribers. When receiving a message from a subscriber of the predetermined set, the Pcard that is designated for the subscriber is determined and the received message is routed to the determined Pcard. The Pcard also has an associated database containing profile information for the subscribers using the Pcard.

The present invention provides a system and method for migrating a control of a wireless communication service provided to a mobile station (MS) in a first network depending on a first technology to a second network depending on a second technology. When receiving a request for the wireless communication service in the first network by a mobile switch center (MSC), at least one instruction is obtained to grant or deny the wireless communication service from a first control device in the second network, the first control device providing the instruction based on its communication to a management subsystem for the control of the wireless communication service. If the wireless communication service is granted, a second control device in the first network controlled by the first control device allows the MS to execute the wireless communication service with a receiver. If the wireless communication service is denied, the second control device in the first network controlled by the first control device prohibits the MS to execute the wireless communication service with the receiver, wherein the first and second control device communicate with each other using a predetermined protocol independent of the network technology used by either the first and the second network, and wherein the first network thus maintains the control of the wireless communication service through the management subsystem connected to the second network without implementing additional management subsystem.

Geographical redundancy and an efficient switchover process to redundant equipment () is achieved by separating active main equipment () and standby redundant equipment in different geographical locations so that failures can be avoided in the event of a natural disaster or other event that affects an entire building or region. In addition, partial switchover can be performed for components or functions that become inoperative to corresponding redundant components in the standby equipment. To provide further redundancy and prevent unneeded switchovers, status or heartbeat messages are transmitted between the active main equipment and standby redundant equipment over two different networks.

Techniques for implementing a push-to-talk feature in a mobile telecommunications environment () involve receiving an indication to activate a push-to-talk service for a first mobile device (()) and identifying a group of mobile devices () associated with the push to-talk service for the first mobile device in response to the indication. The indication is received in an unstructured supplementary service data message. A notification relating to the indication to activate the push-to-talk service for the first mobile device is sent to one or more mobile devices from the identified group of mobile devices.
