Abstract: A method, apparatus and computer-readable medium for improving push-to-talk call setup speed by disabling an idle mode of a mobile station are provided. According to the method, a deregistration request is received from a mobile station. The base station determines whether a push-to-talk service flow exists for the mobile station, based upon a unique identifier for push-to-talk service flow for the mobile station. If the service flow does exist, then the base station transmits a deregistration command to the mobile station including an action code that instructs the mobile station to disable its idle mode and change its mobility feature supported field to sleep only mode. Since the time required to transition from sleep mode to active mode is less than from idle mode to sleep mode, the push-to-talk call setup speed is improved.

Abstract: Systems and methods for multimedia messaging are provided. When a multimedia messaging service center (MMS-C) receives an MMS message for an intended recipient, the MMS-C forms an MMS notification message that includes the MMS message. The MMS-C then sends the MMS notification message to an intended recipient independent of receipt of a retrieval request from the recipient.

Abstract: A method and system for priority handling of a dispatch call in a dispatch network is disclosed. A dispatch call request message from a mobile communications unit is received at a dispatch cell site. The cell site determines whether a DAP is configured for operation in a call request reject mode. The cell site determines a priority level of the mobile communications unit if the DAP is configured in the call request reject mode. When the priority level meets a defined threshold, the cell site forwards the dispatch call request message to the DAP and the DAP processes the dispatch call request message.

Abstract: A simulation platform for early evaluation of the performance of a cdma2000 radio access network uses a generic network simulator as the core simulation engine. The simulation platform includes a mobile device simulation module configured to simulate communications between mobile devices and radio access networks, and a network application simulation module configured to simulate network application functionality. In one embodiment, the network simulation engine, mobile device simulation module and the network application simulation module are linked to emulate end-to-end network communications.

Abstract: Systems and methods for priority wireless communications are provided. When a priority mobile station is registered with a wireless communication network, one or more base stations can establish a priority control channel for serving the priority mobile station. The priority control channel can be an uplink control channel for sending call setup requests, such as traffic channel allocations. The priority control channel can also be a downlink control channel for sending information to priority mobile stations.

Abstract: A method and system for providing an originating dispatch user with delivery options when a destination dispatch user is not available are provided. These options can include delivering buffered voice to a voice mail system, and converting the buffered voice to text and sending the text as an electronic mail, a short message service (SMS) message, or an instant message. The speech can be buffered in either the network or in the originating communication device. The speech can be buffered either before or after receiving a call setup acknowledgment from the dispatch network.

Abstract: Systems and methods for a gateway that couples two or more networks are provided. The gateway allows mobile stations with subscriptions in one network to roam and operate in another network. The networks that can be coupled by the gateway include CDMA-based networks, GSM-based networks, iDEN-based network and WiMAX-based networks.

Abstract: Systems and methods are provided for establishing a communication session. A communication setup request with a service address may be received by a communication server from a first communication device. At least two communication devices associated with the service address may be identified. The communication server may transmit a call setup request to the at least two communication devices. A communication session can be established exclusively between the first communication device and a first one of the at least two communication devices that responds to the call setup request.

Abstract: Systems and methods for wireless network planning are provided. The wireless network capacity forecast can account for different usage patterns of different types of wireless communication services and/or of prepaid and postpaid mobile stations. The wireless network capacity forecast can also account for an ability of different mobile stations with different capabilities to operate in different frequency bands. The wireless network capacity forecast can identify base sites that should be split into two or more base sites.

Abstract: A system and method for creating a custom-developed service by a customer in a service directory of a network service provider are provided. The data defining the custom-developed service received by the network service provider may be tested, corrected, and verified. The service directory may be established in the provider's network to store the data associated with the custom-developed service. Once the custom-developed service is established and operational, the customer or its subscribers may be billed based on their use of the service.

Abstract: Systems and methods of allocating radio resources are provided. The systems and methods involve assigning each of a plurality of mobile stations to one of a plurality of categories, wherein each of the plurality of categories is associated with a different resource allocation scheme. An amount of available radio resources is allocated to each of the plurality of categories. An amount radio resources assigned to each category is allocated to mobile stations assigned to the category based on the resource allocation scheme associated with the category.

Abstract: Systems and methods of providing push-to-application services are provided. A network includes a push-to-application session controller that manages a push-to-application session between an application and a client. The network also includes a media controller, coupled to the session controller, that transfers media between the client and the application. The network further includes an application synchronizer, coupled to the session controller, that controls synchronization between media provided by the media controller to the client and data provided by the application to the client.

Abstract: A print server and method for forwarding printing data in a network are provided. The print server receives an IP address of a printer and a uniform resource identifier of printing data from a mobile station. The print server determines which printer corresponds to the IP address and forwards the printing data to the printer for printing, thereby allowing a mobile station to print data in remote locations. The mobile station does not have to format the printing data or transmit the formatted printing data, thereby reducing the burden on the operating system and the storage space of the mobile station.

According to the method, group setup information is received from a member of the push-to-talk social group, and a data transmission, including an internet address of an internet application that manages push-to-talk social groups, is sent to each member of the push-to-talk social group. Push-to-talk calling may be monitored in a push-to-talk gateway application, based upon the group setup information. When a push-to-talk call is detected in which a first member of the push-to-talk social group is active, other members of the push-to-talk social group are informed that the first member is active on the detected push-to-talk call. Other members of the group may then initiate a push-to-talk call with the first member.
