Abstract: A method to transmit a broadband multimedia resource locator using a narrowband communication system embeds the broadband multimedia resource locator into a narrowband audio stream and transmits the narrowband audio stream to one or more receiving communication devices over the narrowband communication system. The receiving communication device(s) subsequently extract the broadband multimedia resource locator from the narrowband audio stream and use the broadband multimedia resource locator to access a broadband communication system to retrieve multimedia content.

Abstract: A method for enabling group communications includes: establishing a group identity for a communication group comprising a first set of communication devices, and storing an identity for each of the communication devices in the first set; establishing a session to associate a second set of communication devices with the group identity, wherein the communication devices in the second set are different from the communication devices in the first set, wherein the session with the second set of communication devices is set up irrespective of a call being initiated for the communication group; detecting a first event associated with the initiation of a call for the communication group; and in response to detecting the first event, using the stored identities to join at least one of the communication devices in the first set to the session.

Abstract: A method (800, 900) for terminating a communication session. The method can include generating a first message (114) requesting permission to terminate participation in the communication session and communicating the first message to a server (108). The method can also include receiving a second message (116) from the server authorizing the participation in the communication session to be terminated and terminating the participation in the communication session.

Abstract: Techniques are provided for enabling application steering/blocking in a secure network which includes a network entity, and a first tunnel endpoint coupled to the network entity over an encrypted tunnel. The first tunnel endpoint associates at least a first Security Parameter Index (SPI) to a first application identifier to generate first mapping information (MI), communicates the first MI to the network entity, and transmits an encrypted message to the network entity over the encrypted tunnel. The encrypted message includes an encrypted packet and an unencrypted header including the first SPI. The network entity determines the first SPI from the unencrypted header, determines the first application identifier based on the first SPI and the first MI, and identifies a first application associated with the first application identifier. The network entity can still perform application steering/blocking even though traffic passing through the tunnel is encrypted.

Abstract: A key management facility for a communication network masquerades as a first device within the communication system during an Internet Key Exchange (IKE) negotiation with a second device within the communication system. The key management facility establishes, on behalf of the first device, a security association with the second device using IKE. After the negotiation is complete, the key management device provides information regarding the security association to the first device such that the first device can engage in an Internet Protocol Security-protected communication with the second device.
