A method for managing UMA communications within a local area network and a network controller includes establishing a first connection between a first UMA device and a LAN-based UMA network controller (LAN-UNC) and establishing a second connection between a second UMA device and the LAN-UNC. The first and second connections are carried over the local area network. The first and second UMA devices are connected to the same local area network. The method provides establishing a third connection between the LAN-UNC and a UMA network controller (UNC). The UNC is connected to an external network and the third connection extends over the external network. The method includes transporting packets received using the first and second connections to the UNC using the third connection. Packets received using the third connection are transported to the first UMA device using the first connection and to the second UMA device using the second connection.

A method for managing UMA communications within a local area network and a network controller are disclosed. The method includes establishing a first connection between a first UMA device and a LAN-based UMA network controller (LAN-UNC) and establishing a second connection between a second UMA device and the LAN-UNC. The first and second connections are carried over the local area network. The first and second UMA devices are connected to the same local area network. The method provides establishing a third connection between the LAN-UNC and a UMA network controller (UNC). The UNC is connected to an external network and the third connection extends over the external network. The method includes transporting packets received using the first and second connections to the UNC using the third connection. Packets received using the third connection are transported to the first UMA device using the first connection and to the second UMA device using the second connection.

Methods, apparatuses, and systems are presented for determining an appropriate transport protocol for supporting Session Initiation Protocol (SIP) communication, which may involve repeatedly sending SIP requests from a first device destined for a second device using at least one transport protocol, attempting to receive responses to the SIP requests at the first device from the second device, based on results of attempting to receive responses to the SIP requests, updating a data record associated with the first device, the data record containing an entry for the second device, the entry for the second device including at least one indication of operability with the at least one transport protocol, and selecting one of the at least one transport protocol, based on the entry for the second device in the data record, as a selected transport protocol for establishing a desired SIP communication between the first device and the second device.

Determination of SIP transport to reduce call setup delays

A method for managing Unlicensed Mobile Access (UMA) communications within a local area network and a LAN-based UMA network controller are disclosed. The method includes monitoring packets received from a first UMA device connected to the local area network and detecting whether they represent a call between the first UMA device and a second UMA device. The method also includes determining whether the second UMA device is connected to the local area network. If the packets represent a call between the first and second UMA devices and the second UMA device is connected to the local area network, packets representing audio data are maintained within the local area network.

LAN-based UMA network controller with local services support

Telephones connected to a gateway can still make calls when connectivity to a central processing device is lost. The gateway determines when connectivity with the central processing device is lost. When a communication is received from a first telephone for second telephone, the communication is routed to the second entity by bypassing the central processing device. This is possible using identification information that is stored for the second entity when the second entity registered with the central processing device.

Gateway to route communications during a fault

A method for establishing a synchronous connection between two terminals over an asynchronous communication transport is provided. The method includes receiving, from a first secure terminal, an indication for establishing a connection with a second secure terminal. The indication is received at a first gateway, which then sends the indication to a second gateway. The first gateway negotiates with the first secure terminal to establish a connection with the first gateway. The negotiation is performed without the first gateway communicating with the second gateway or the second secure terminal. A second gateway also negotiates with the second secure terminal to establish a connection with the second gateway. When it is determined that the first secure terminal and first gateway have established a first connection and the second secure terminal and second gateway have established a second connection, a connection between the first secure terminal and the second secure terminal is established through the first gateway and the second gateway.

Non-relay initialization for modems

Techniques for compensating for synchronous data stream transported over an asynchronous system are provided. The techniques include compensating for network jitter for an asynchronous connection over an asynchronous transport, using frame slip control for compensating for a synchronous connection over an asynchronous transport, and dropping filler frames for compensating for a synchronous connection over an asynchronous transport.

A system for providing network access translation device traversal to facilitate communications is provided. The system includes a network access translation (NAT) device, a first Session Initiation Protocol (SIP) client located on the interior of the NAT device, a second SIP client located on the exterior of the NAT device, and a proxy server configured to maintain registration information relating to the first SIP client and the NAT device. The proxy server is further configured to allow the second SIP client to initiate contact with the first SIP client and establish a communication session using the registration information. The communication session is established by traversing the NAT device.

Methods, apparatus, and systems are presented for communicating structured data in a system utilizing devices having different data processing capabilities. The methods, apparatus, and systems involve transmitting a unit of data from a first device, wherein the unit of data comprises at least a version-specific portion and a version identifier associated with the version-specific portion, receiving the unit of data at a second device distinct from the first device, processing the version-specific portion at the second device if the second device recognizes the associated version identifier, and disregarding the version-specific portion at the second device if the second device does not recognize the associated version identifier. Disregarding the version-specific portion may comprise examining a data length field in the data unit associated with the version-specific portion to determine a length value and skipping an amount of data corresponding to the length value.

Structured data communication with backwards compatibility

A method is provided for forward error correction for packets of information transmitted in a network. In one example, the method includes adding redundant information to the packets to be transmitted; transmitting the packets, wherein many of the packets become arrived packets, and wherein one or more of the packets becomes one or more lost packets; and restoring the one or more lost packets using redundant information of the arrived packets.
