20100128716 | Method and apparatus for providing network based services to private branch exchange endpoints - Many of the current IMS standards and enriched services were originally designed for the individual subscribers that are serviced by the wireless network. However, the IMS standards do not fully address the problem of providing the IMS enriched services and features to users connected to a PBX. The present invention discloses a method for providing IMS enriched services and features to users connected to a PBX or an IP-PBX. Access to network services can be secured through a web-friendly interface via the IMS, enabling third-party developers, service providers and even subscribers to self-manage their service experience while the network operator retains control over network resources. | 05-27-2010 |
20100150137 | IMS and Method of Multiple S-CSCF Operation in Support of Single PUID - A method for providing multimedia services to subscriber user equipment (UE) within an IP multimedia subsystem network (IMS) may include configuring the IMS to enable a single UE to fork register and cooperate with multiple serving-call session control functions (S-CSCFs). After obtaining IP connectivity, the single UE signals to register with the IMS and the IMS determines whether the UE is configured to fork register with multiple S-CSCFs. If the UE is configured, the IMS determines which S-CSCFs are eligible for the UE registration and fork registers the UE to multiple S-CSCFs of the eligible S-CSCFs. Consequently, incoming and outgoing calls to/from the UE are routed by the IMS to any of the multiple registered S-CSCFs. | 06-17-2010 |
20100153567 | Method and Apparatus for Providing Network Based Services to Non-registering EndPoints - Many of the current IMS standards and enriched services were originally designed for the individual subscribers that are serviced by the wireless network. However, the IMS standards do not fully address the problem of providing the IMS enriched services and features to business PBX customers or wholesale customers that do not directly register to the IMS network. The present invention discloses a method for providing IMS enriched services and features to business PBX customers or wholesale customers through the use of a static provisioning and registration method. | 06-17-2010 |
20100197286 | System and Method for Improving Cellular Telephone User Experience - A method for determining an amount of time required to download a data file to a wireless device includes receiving information indicating a first amount of wireless bandwidth allocated for the download of the data file, calculating a first length of time required to download the data file to the wireless device based on the first amount of wireless bandwidth allocated, and comparing the first length of time required to a predetermined amount of time. If the first length of time required is less than the predetermined amount of time, the download begins. If the first length of time required is more than the predetermined amount of time, information indicating the first length of time required is sent to the wireless device, a start download signal is received from the wireless device, and download of the data file to the wireless device begins in response to the start download signal. | 08-05-2010 |
20100233991 | METHOD TO IMPLEMENT E911 SERVICES IN IMS (IP MULTIMEDIA SUBSYSTEM) - A system and method that facilitates processing and/or routing of emergency call in an IMS (IP Multimedia Subsystem) for VoIP (Voice over IP) subscribers is provided. Specifically, an E911 profile is generated, for example, by an application server, for each VoIP subscriber based in part on current location information associated with the subscriber, such as, the subscriber's IP address. The E911 profile is pushed to the HSS (Home Subscriber Server) of the IMS. The E911 profile can then be stored in the HSS and can be queried by an E-CSCF (Emergency Call Session Control Function) during emergency call processing. Moreover, when an emergency call is received from the subscriber, the E-CSCF can retrieve the E911 profile associated with the subscriber from the HSS and route the call to an appropriate PSAP (Public Safety Answering Point) based on an analysis of the information in the E911 profile. | 09-16-2010 |

20120044861 | CONTROL DOMAIN CHANGE BASED ON NETWORK REGISTRATION CONDITION - Aspects describe a separate domain selection function that is utilized as the first function in a communication path for a communication that is to be connected to a user device registered in a first network or a second network. If a result of the domain selection function indicates call control should be maintained by first network (e.g., user device is registered with first network or a network with which first network has a control relationship), call control of the communication remains with first network. If the result of the domain selection function indicates the user device is registered with second network, call control is suspended by the first network, which allows the communication to bypass the first network. | 02-23-2012 |
