20130128828 | Compromise Resource Allocation Field Size When Aggregating Component Carriers of Differing Size - Methods and arrangements for resource allocation in a telecommunication system in which aggregation of component carriers is applied. The size of the resource allocation field is determined based on the transmission bandwidth of a selection of component carriers. The selection of component carriers comprises the component carrier on which the resource allocation message is monitored and the component carriers which are cross-scheduled from said component carrier.

The second media path extends between the originating device and a second destination device, the second media path not including the communication session controller. | 2013-05-23 |

20130128880 | System and Method for Dynamic Telephony Resource Allocation Between Premise and Hosted Facilities - A population of networked Application Gateway Centers or voice centers provides telephony resources. The telephony application for a call number is typically created by a user in XML (Extended Markup Language) with predefined telephony XML tags and deployed on a website. A voice center provides facility for retrieving the associated XML application from its website and processing the call accordingly. The individual voice centers are either operated at a hosted facility or at a customer's premise. Provisioning Management Servers help to allocate telephony resources among the voice centers. This is accomplished by suitably updating a voice center directory. In this way, the original capacity at a premise, predetermined by the hardware installed, can be adjusted up or down. If the premise is under capacity, it can be supplemented by that from a hosted facility. If the premise has surplus capacity, it can be reallocated for use by others outside the premise. | 2013-05-23 |
20130128881 | Method and System of Voice Carry Over for Instant Messaging Relay Services - A method of assisting communication for a user is provided. The method includes receiving an IM message including a request for a voice carry over from the user, and transmitting to the user an invitation to join a first voice connection. The method further includes initiating the first voice connection with the user, and initiating a second voice connection with a recipient. Additionally, the method includes communicating to the recipient a first voice communication from the user over the first and second voice connections, and communicating to the user a response IM message including a transcribed version of a second voice communication from the recipient. An apparatus for assisting communication for a user is provided. A computer-readable medium having stored thereon computer-executable instructions is provided. The computer-executable instructions cause a processor to perform a method when executed. | 2013-05-23 |
20130128882 | SYSTEM AND METHOD FOR PROCESSING TELEPHONY SESSIONS - In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource. | 2013-05-23 |
