    摘要: The invention is CDMA quadrature signal technology that controls the transmit power of a CDMA signal. The CDMA quadrature signal technology receives a CDMA signal, and in response, process quadrature components of the CDMA signal to generate a power control signal. The CDMA quadrature signal technology adjusts the gain of the CDMA signal in response to the power control signal. A CDMA transmitter transmits the CDMA signal after the gain is adjusted. One example of the CDMA transmitter is a CDMA base station. Using the invention, a multi-sector CDMA base station can control power without transferring gain information to base station components for all sectors. The invention eliminates unnecessary data transfer and storage.

    摘要: A system and method for enabling a UE to roam to a visited IMS-based network from a home network that does not have an IMS infrastructure. A visiting UE sends to an Intelligent Roaming Application Server (I-RAS) in the visited network, a first SIP Registration message that includes a SIP URI identifying the UE as a visitor from a home network that does not have an IMS infrastructure. The I-RAS rejects the registration, but includes a temporary Tel URI in the rejection message. The UE sends a second Registration message using the temporary Tel URI, which is forwarded to a Visited S-CSCF for authentication. The S-CSCF returns authentication vectors, which the UE uses to compute ciphering parameters and establish an IPSEC connection with a Visited P-CSCF. The UE then sends a third Registration message, which is accepted, and registration in the visited network is complete. The I-RAS acts as a pseudo Visited MSC/VLR and performs an update location procedure with the visiting UE's home network.

    摘要: In an Internet Protocol Multimedia Subsystem (IMS), a user profile is provided with an extended schema that provides one or more error code definitions and associated error handling instructions. Response codes received in response to requests to an application server are processed to determine if a matching response code is defined in the user profile. If a match is found, the associated response handling instructions are performed. If no match is found, a default response handling is performed.
