Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 21/20

US Classification:

726 4

Abstract:

A relay server authentication service for a relay server is described. An apparatus may include a proxy server to receive an authentication request for client authentication information from a first client to traverse a network address translation device. The apparatus may further include a relay server with a relay server authentication service module. The relay server authentication service module may be arranged to receive the authentication request from the proxy server, generate the client authentication information for the first client, and send an authentication response with the client authentication information to the first client through the proxy server. Other embodiments are described and claimed.

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

H04L 12/56

US Classification:

370401

Abstract:

Techniques to manage a relay server and a network address translator are described. A system may include a relay server having a first private network interface operative to communicate with a private client, a second private network interface operative to communicate with a network address translator, and an enhanced relay manager module operative to receive a message from the private client over the first private network interface or a remote client over the second private network interface and through the network address translator, the enhanced relay manager module further operative to retrieve a public transport address and a mapped port for the network address translator from a mapped address attribute stored by the relay server, and send a response to the message with the public transport address and the mapped port to the private client or the remote client. Other embodiments are described and claimed.

International Classification:

G06F 15/16

US Classification:

709228

Abstract:

Techniques to manage communications between relay servers are described. A system may include multiple relay servers each having an enhanced relay control module. The enhanced relay control module may be operative to manage communications between private clients communicating over the first relay server and the second relay server. The enhanced relay control module may establish a media channel between control ports for the first and second relay servers when a port range attribute for at least one of the first or second relay servers is turned off. Other embodiments are described and claimed.

US Classification:

370331

Abstract:

Voice call continuity is provided for calls that are carried over a hybrid network infrastructure in which access connections are distributed over loosely coupled network portions including a backend network such as a core VoIP (Voice over Internet Protocol) service network, one or more cellular mobile networks, and a public switched telephone network (“PSTN”). The calls are routed through the core VoIP network regardless of their points of origination or termination in other network portions so that signaling and call context are anchored in the core VoIP network. The conditions under which user equipment operate are continuously monitored so that when a connection is determined to have been unacceptably degraded or is likely to be interrupted, and/or a more optimal connection is available, a handover of the call to another connection is initiated so that call continuity is maintained using the lowest cost connection that provides acceptable call quality.
