Techniques for session transfer between resources are described in which session data for communication sessions is transferred between distinct web-based resources to enable continuation of the communication sessions as navigation between the resources occurs. In one approach, shared session storage accessible to authorized resources is employed to facilitate the transfer of session data. Code embedded in pages for different resources rendered by a browser (or other communication module) operates to store session data for communication sessions in the shared storage. When navigation occurs between different pages, authorizations of the different resources to utilize the shared session storage are determined and communication sessions that are active are maintained across page reloads for the authorized resources. This involves retrieving session data stored in the shared session storage and passing the session data that is retrieved to a communication service to reconnect to the communication sessions after navigation occurs.

Session transfer between resources

In one embodiment, a method includes receiving a request at a wireless access point from a client system to access a network through the wireless access point. The wireless access point sends an identifier associated with the client system to a social-networking system, the social-networking system including user profiles arranged in one or more social graphs. The social graphs store relationships between the user profiles. The method further includes receiving at the wireless access point from the social-networking system an authorization determination. The authorization determination is based upon a first user profile of the plurality of user profiles. The first user profile includes the identifier associated with the client system. The method further includes providing the client system with access to the network through the wireless access point in accordance with the authorization determination.

Network access based on social-networking information

In one embodiment, a mobile device connecting to a Wi-Fi hotspot first performs a connectivity check to determine whether the wireless connection is trapped in the walled garden of a captive portal by transmitting a connectivity check message to one or more external endpoints in the public IP network. If no response is received, the mobile device determines that it is in the captive portal state, and generates a browser window bound to the Wi-Fi state tracker of the mobile device displaying the portal page for the captive portal. In such a manner, the mobile device does not offload any traffic from its wireless cellular interface to its Wi-Fi interface until it is certain the Wi-Fi interface may access the public IP network, thereby preventing data interruption for mobile applications.

Captive portal state detection and avoidance for multiple-interface traffic offloading

Techniques to manage digital telephones are described. An apparatus may comprise a digital telephone management component having a telephone interface module operative to receive security information in the form of a personal identification number (PIN) for an operator or device. The digital telephone management component may also comprise a telephone security module communicatively coupled to the telephone interface module, the telephone security module operative to receive encrypted security credentials from a computing device, and decrypt the encrypted security credentials with the PIN. The digital telephone management component may further comprise a telephone authentication module communicatively coupled to the telephone security module, the telephone authentication module operative to authenticate the digital telephone using the security credentials. Other embodiments are described and claimed.

Architecture for enabling user identities of callers to be collected from data sources and aggregated into respective meta-identities for each caller. Alternate user identities are searched, collected and associated with the meta-identity that can be a user name. A routing rule applied to the meta-identity is then applied across the alternate identities. The user identities can include a name of the caller, a phone number of the caller, or caller information collected from an external source. The phone numbers can include a partial phone number that is normalized into a full phone number format. The user identities can be mapped to the meta-identity and stored according to a hierarchy of confidence ratings. The user identities can be tagged with corresponding data source identifiers that designate respective data sources of the user identities. Conflict resolution is provided for selecting a suitable call routing path between callers having similar meta-identities.

An architecture for an extensible real-time collaboration system is provided. The architecture presents a unified application program interface for writing application programs that use communications protocols. The architecture has activity objects, endpoint objects, and multiple media stacks. These objects may use various communications protocols, such as Session Initiation Protocol or Real-Time Transport Protocol to send and receive messages. The activity objects, endpoint objects, and multiple media stacks may each have one or more APIs that an application developer can use to access or provide collaboration-related functionality. These objects map the API to the underlying implementation provided by other objects. Using the activity objects enables a developer to provide less application logic than would otherwise be necessary to provide complex collaboration services.

In one embodiment, a user paired controller communication device may pair with a user paired server communication device. The user paired controller communication device may direct the user paired server communication device to execute a first mode communication session of a multimodal conversation, such as a voice session. The user paired controller communication may execute a second mode communication session of the multimodal conversation, such as an instant messaging session.

Remote call control and conferencing using paired devices

Multiple peripheral devices are used for various modes of communication in a unified communication application. Employing standard or custom protocols, connected peripheral devices can be configured automatically and different modes of communication such as audio, video, data, and text, are routed to available or selected peripheral devices. Incoming communication requests can be extended to multiple peripheral devices synchronously and users enabled to switch between peripheral devices seamlessly during a communication session.

Dynamic call handling from multiple attached devices wherein devices advertize its capabililes before facilitating call through appropriate device

A facility for providing extensible alert types is described. The facility includes an endpoint component that has an associated application, an alert handler component provided by the application for handling received messages and providing alerts to the application, and a message transport component that receives a message, determines whether the message contains an alert, locates an alert handler to handle the alert, and provides a portion of the received message to the alert handler component so that the alert handler component can handle the alert. The facility can receive a request to register an alert handler, add an indication of the alert handler in a mapping data structure and, upon receiving a message containing an alert, identify an alert handler to handle the alert contained in the message.

Extensible alert types

A facility is described for managing parallel requests in a communications environment having devices or applications ('request handlers') that support serial and parallel message processing. In various embodiments, the facility receives messages directed to a recipient from an application and sends a first message to the recipient without sending subsequently received messages to the recipient. Upon receiving a response from the recipient to the first message, the facility determines whether the recipient supports parallel or serial message processing. When the recipient supports parallel message processing, the facility sends the subsequently received messages to the recipient without awaiting a response to a message before sending another message. When the recipient supports serial message processing, the facility sends a subsequent message after receiving a response to a previously sent message.
