A multimedia call model is provided to handle, maintain and control multimedia calls and their interactions in a network entity () for an end-user in the network. The call model provides a first Call Control Process (CCP) () having a first media service type and associated with a first group of agents (), and a second CCP () having a second media service type and associated with a second group of agents (). The call model also provides a Multimedia Call Process (MMCP) () for facilitating the arrangement and/or communication between the two CCPs.

Method and system for providing a multimedia call model

A method and system is disclosed for providing data services to a wireless mobile in a hybrid network.

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.

Provided is a method and system for minimizing call setup delay in a network. The system includes a central node that may be connected to multiple home location registers (HLRs) and a number portability database (NPDB). The central node may also be associated with two tables. The first table includes mobile station identifiers and associated location routing numbers (LRNs), and the second table includes mobile station identifiers and associated home location registers (HLRs). The method searches the first and second tables for a mobile station identifier that matches a mobile station identifier associated with a call. If a match is found, the method uses the associated LRN or HLR to continue with the call setup or to obtain further information. If no match is found, the method sends a query to the NPDB. The method may also dynamically update the first and second tables as current information is obtained.

Calls are routed in a distributed mobile switching center environment in response to receiving a call to be routed from a first switching mode (() to a second switching node (()). An inter-switch mute for the call from the first switching node to the second switching node is identified. The inter-switch route includes an intermediate switching node () having multiple media gateway (). An intra-switch route within the intermediate switching node is selected from multiple possible intra-switch routes for use in establishing the inter-switch route. Each of the intra-switch routes includes one or more interconnections () between media gateways. The call is connected using the identified inter-switch route and the selected intra-switch route.

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.

Method and system for providing availability and reliability for a telecommunication network entity

Provided is a method and system for enabling mobile devices, radio access networks (RANs), and core networks (CNs) based on different specifications and underlying technologies to communicate. The mobile device and the RAN may be based on one technology, such as a code division multiple access (CDMA) specification, while the CN may be based on another technology, such as a global system for mobile communications (GSM) specification. The method takes a CDMA message received by the RAN, converts it into a corresponding GSM message, and passes it to the CN. Alternatively, a new GSM message may be created. Similarly, a GSM message from the CN may be converted into a CDMA message (or a new CDMA message may be created) and the CDMA message passed on to the RAN. The method may also initiate a function or procedure in one portion of a network using one technology when a certain message is received from another portion of the network using a different technology. This provides a cost-effective and flexible process that, among other advantages, enables the mobile device to communicate with incompatible CNs.

Method and system for providing wireless services using an access network and a core network based on different technologies

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.
