Abstract: A portable communication device operating of a first WWAN can receive an identifier from a WLAN access point indicating that one or more devices operating on a second WWAN are in the vicinity of the WLAN access point. In response, the portable communication device invokes an interference mitigation process while the identifier indicates that devices operating on the second WWAN are present.

Abstract: A method and apparatus for providing acknowledgment information for radio communication devices in a wireless communication system. A base station receives a plurality of units of data each respectively transmitted by one of a plurality of radio communication devices on one of a plurality of predetermined communication slot positions of a first channel. The base station, in response to receiving the data messages, sends a control message on a communication slot position of a second channel. The control message includes acknowledgment information having a plurality of positional acknowledgment indicators. Each radio communication device receives the control message and uses acknowledgment position mapping information to identify one or more positions within the plurality of positional acknowledgment indicators that contains an acknowledgment to the respective units of data it transmitted on the corresponding predetermined communication slot positions of the first channel.

Abstract: A multi-carrier receiver radio monitors frequency channels associated with at least one talkgroup to which a multi-carrier receiver radio subscribes. The talkgroup is associated with a set of frequency channels that may carry group call activity. The radio monitors each frequency channel of the set of frequency channels associated with the talkgroup for group call activity. During monitoring, when a new call is detected on one frequency channel of the set of frequency channels associated with the talkgroup, the radio joins the new call. While joined to the new call, the radio continues to monitor the set of frequency channels associated with the talkgroup for additional transmissions to the talkgroup and to monitor a set of frequency channels associated with another talkgroup to which the multi-carrier receiver radio also subscribes for group call activity on the other talkgroup.

Abstract: An incident commander computing device dynamically reconfigures subscriber unit usage of radio access networks by first identifying, based at least on a type of incident occurring within a particular geographic area, a first incident response group having a first higher priority for responding to the incident and a second incident response group having a second lower priority for responding to the incident, then identifying a first higher priority radio access network having a sufficient coverage level across the particular geographic area and a second lower priority radio access network having a sufficient coverage level across the particular geographic area, and finally assigning the first incident response group to the first higher priority radio access network and assigning the second incident response group to the second lower priority radio access network.

Abstract: A method and apparatus for simulcasting within a communication system is provided herein. During operation, each base site will be equipped with a plurality of radios capable of transmitting on various frequencies. Base sites within the communication system will be capable of communicating on a predetermined number of channels, which may differ among base sites. A number of channels will be shared by the base sites. When a simulcast is desired, the participants are located, and a common channel is determined for communication. Thus, call participant location information is used to determine the best channel to use to meet the group's coverage needs.

Abstract: At least one subscriber unit (SU) (110) can register with a radio frequency (RF) site (120) for radio services. For each registered SU, a SU push to talk over cellular (PoC) client (342-346) can be activated/established. Communications can be mapped at the RF Site (120) between each registered SU (110) and a corresponding SU PoC client (342-346). Each SU PoC client (342-346) at the RF site (120) can be communicatively linked to a remotely located PoC server (132) using a PoC interface (226). The SU PoC client (342-346) is a communication endpoint of the PoC server (132). In one embodiment, a talkgroup PoC client (350-352) can be established at the RF site (120) that is linked to the PoC server (132). Radio communications to and from the SU (110) can be routed through the SU PoC client (342-346) and/or the talkgroup PoC client (350-352) and through the PoC server (132).

Abstract: A method and system for operational improvements in a dispatch console in a multi-source environment includes receiving (310) a plurality of audio streams simultaneously from a plurality of mobile devices, transcribing received audio streams by the means of speech-to-text conversion, presenting real-time transcriptions to the user and determining (320) if a first keyword is present in at least one of the plurality of audio and/or text streams. Upon determining the presence of the first keyword, the dispatch console automatically performs (330) at least one predefined dispatch console operation from a list of predefined dispatch console operations. The dispatch console further receives (340) a second keyword based on determining the presence of the first keyword and checks (350) for the presence of the second keyword within the audio and/or text streams thereby enabling additional automated dispatch console operations.

Abstract: A method and a system for improving Web hosting performance, enhancing content distribution and security on the Internet and stabilizing WEB Site connectivity, by means of creating a TCP terminating buffer around subscriber WEB Sites. A DNS agent diverts client requests to WEB Sites to a Virtual Host Accelerating (VHA) Site in closest proximity. The VHA Site comprises a set of physically identical computer units and processing is enhanced on those units by means of a hardware devise to accelerate database searches. The VHA determines if the client request is of a permitted type and if the request can be processed from recycled data. Both static and dynamic requests can be serviced from recycled material and only in certain circumstances are requests forwarded to the WEB Sites by means of permanent open connections. In some cases SSL requests are also served from recycled material.

Abstract: A method and apparatus for securing digital data, and applications for securing multiple data items such as multiple files or messages exchanged between two communicating parties. The methods use a randomly created non-repetitive codec, with which the information to be encrypted is XORed. The codec is XORed with a user initial key, and the two results are concatenated. For securing multiple items, a master file is created comprising a number of keys, while the master file itself is encrypted with the initial key. A communication application enables a login-free communication between a client and a server, thus blocking intrusion attempts on the client side, and pishing attempts on the server side.
