A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

A method for providing local cordless service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roans from one zone to another, the subscriber may continue their fee call uninterrupted and without paying air time charges. However, when the subscriber roans outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges. However for an active call, No air-time charges are incurred as the user transitions between the cellular/DPCS environment and the local cordless service environment.

Systems and methods for facilitating wireless intercom in a local communications network are disclosed. Exemplary implementations may: generate and transmit a first broadcast packet and a second broadcast packet to a set of end-user communication devices; receive a first device-specific packet, on a first channel by a first central antenna and during a first uplink time period; receive a second device-specific packet, on the first channel by the first central antenna and during a second uplink time period; receive the first device-specific packet, on a second channel by a second central antenna and during a third uplink time period; receive the second device-specific packet, on the second channel by the second central antenna and during a fourth uplink time period; generate a third broadcast packet that includes packetized downlink information; and transmit the third broadcast packet to the set of end-user communication devices.

A method of establishing a communication link between a mobile terminal of a wireless network and a subscriber of a network, such as an enterprise network, and/or a residential network.

A method of routing calls from a mobile unit to a destination location can include registering the mobile unit with a wireless adjunct, wherein the wireless adjunct is in communication with a switching unit and a packet based network and is operable to receive data from the switching unit and place the data, in packetized form, on the packet based network. The method can further include responding to a call setup request from the mobile unit and querying a subscriber database to determine if the mobile unit is a resident or a guest. If the mobile unit is a resident, communications data can be routed from the mobile unit through the switching unit to a first destination location. If the mobile unit is a guest, communications data can be routed from the mobile unit through an RF source to a second destination location.

Methods and systems for instant activation of virtual PBX services on a mobile device are disclosed. In one aspect, a user request for activating virtual PBX services is received on a mobile device. An available primary identification number for the virtual PBX services is retrieved from a telecommunication service provider (TSP). A user interface is presented on the mobile device including a first interface portion presenting the available primary identification number and a second interface portion configured to receive a user identifier. Upon receiving the user input specifying the user identifier and while the user interface is still presented on the mobile device, a user instruction for activating the virtual PBX services is received. Upon receiving the user instruction, the user identifier is sent to the TSP. Then, a confirmation is received from the TSP.

Cordless telephone equipment includes a portable unit and a base unit. The base unit includes: a portable unit control section controlling a communication protocol with the portable unit through a wireless interface wirelessly connecting with the non-IP terminal type portable unit; a wireless LAN interface section transmitting and receiving packet data to and from a wireless IP terminal and wireless LAN access point; a wireless LAN bridge control section forwarding the received packet data to the wireless IP terminal, or the wireless LAN access point, or within the base unit in accordance with a destination address of the packet data received through the wireless LAN interface section; and a base unit control section processing the packet data received from the wireless IP terminal and forwarded within the base unit, as data received from a portable unit under control of the base unit.

In an embodiment, a bridge circuit is configured for connecting a desk phone (e.g., a VoIP phone) to a mobile device (e.g., a smart phone), while allowing the existing desk-phone VoIP/PSTN system (e.g., a PBX system) to be eliminated with significant savings in reduced telecommunication-infrastructure costs. The bridge circuit can be powered through traditional wall power, and can include a CAT 5 cable port with Power Over Ethernet (PoE), a PSTN port such as an RJ11 port, a set of electronics that provide wireless connectivity to the mobile device, a control circuit, and a set of software instructions for programming the desk phone to communicate with the bridge circuit and for providing other features such as conference calling, putting a call on hold, and transferring contact information from the mobile device to the desk phone or vice-versa.

A system, method and computer-readable medium for allowing the use of an alternative numbering plan for delivering short messages to mobile subscribers using the public mobile telephone network is provided. Users of an enterprise or other closed networks as well as users that are not part of a closed network may send short messages destined to members of an enterprise or closed network from their mobile or other devices associated with their subscription using an alternative enterprise directory number, such as the office number, instead of the mobile number, such that the alternative number will be presented at the destination device as the originating number. The recipient may respond to the message by addressing the response to the enterprise or closed network number, and the response may be delivered to the originator's mobile or other device associated with their subscription.

In nurse call systems that enable communication from a plurality of cordless handsets with a plurality of extension terminals carried by nurses belonging to a group, a nurse call conversion unit is provided between a nurse call control device and a private branch exchange. A call signal for a group representative call in which only an identification number for a group is given is transmitted by the nurse call conversion unit from the nurse call control device to the private branch exchange. From this call signal, the private branch exchange generates a call signal for extension terminals belonging to a group and calls the extension terminals.
