  • Patent number: 7623882
    Abstract: Systems of methods for performing queued and moderated talk groups in a system featuring network provided half duplex communications talk group sessions. For queuing, rather than dropping a talk request from a user which is listening, the request is forwarded to the network and maintained in a list which is the used to grant access to the talk channel. For moderated talk groups, a wireless device is designated to be a moderator network device. The requests for the talk channel are then forwarded to the moderator network device. The moderator network device is equipped with functionality allowing a user of the device to select the order in which devices are granted the talk channel. In other implementations, meta-groups are provided, and rules of order for talk group sessions are implemented.

  • Publication number: 20090245158
    Abstract: In one embodiment, a scheme is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. Upon detecting that a cause code has been returned by a node disposed in a wireless packet data service network, a structure is interrogated to determine if the cause code is mapped to a flag relating to the device's data session retry mechanism. Responsive to determining that the received cause code is mapped as a critical cause code, the data session retry mechanism of the mobile communications device is disabled so that further signaling messages towards the network are prevented.

  • Publication number: 20090232055
    Abstract: An apparatus and method of controlling unsolicited traffic are disclosed herein. The apparatus and method can be applied to wireless communication networks such as CDMA2000, UMTS, GPRS and the like so that traffic which is not solicited by wireless communication devices operating on those networks is not sent over the air needlessly. The present application provides techniques to block unsolicited traffic based on the identity of a user (for example based on International Mobile Station Identity (IMSI), Network Access Identifier (NAI), Mobile Station Internet Services Digital Network Number (MSISDN), Session Initiation Protocol (SIP) Universal Resource Locator (url)) as opposed to techniques that are based on a session or IP address, such as a traditional firewall. In accordance to this application, user identity based techniques are applied to block unsolicited traffic whenever a user has established a data session.

  • Publication number: 20080293407
    Abstract: Wireless devices and methods are provided for performing mobile discovery of an active data subscription. This involves a wireless device attempting to register using an APN that is one of a CDMA-centric APN and a GSM-centric APN. If that attempt fails, then the wireless device attempts to register using an APN that is the other of the CDMA-centric APN and the GSM-centric APN. In some cases the first APN attempted is always the CDMA-centric APN; in some cases the first APN attempted is a previously successfully used APN. For wireless devices with a data roaming enable/disable mechanism, the method can be executed while data roaming is disabled such that when data roaming is enabled, the proper APN to use will have been previously identified.

  • Publication number: 20080182614
    Abstract: Devices and methods are provided for configuring multi-mode mobile stations. When the number of data sessions available to a multi-mode mobile station changes, the multi-mode mobile station sends information to configuration server sufficient to determine the capability of the network and identify the multi-mode mobile station. The number of data sessions available to a multi-mode mobile station may change for example due to the multi-mode mobile entering a network, changing radio access technologies (RAT) used in the network or changing radio network controllers having the same or a different respective number of data sessions. A configuration server receives the information sent by the multi-mode mobile station and selects configuration information for configuring the multi-mode mobile station to support services/applications that are subscribed to by a user of the multi-mode mobile station.
