Abstract:
A method and apparatus is provided for communication between a first terminal capable of using both a Circuit Switched (CS) call and an Internet Protocol Multimedia Subsystem (IMS) session, and a second terminal capable of using the IMS session, in a communication system supporting a Combined CS call and IMS session (CSI service). If the second terminal sends a Session Initiation Protocol (SIP) request (INVITE) message to originate a voice service or a multimedia service including the voice service with the first terminal, a CSI Application Server (AS) of an IMS domain managing the first terminal separates a voice service-related component included in the request message from a multimedia service-related component, and generates and sends first and second request messages to the first terminal. Upon receipt of first and second response messages corresponding to the first and second request messages from the first terminal, the CSI AS generates a combined response message and sends the combined response message to the second terminal.
Abstract:
A method and system in which upon occurrence of a P-CSCF failure, a network sends an IMS reregistration request message to a UE. An S-CSCF or an AS monitors a P-CSCF to detect occurrence of a failure in the P-CSCF. Upon detecting the occurrence of a P-CSCF failure, the S-CSCF or the AS sends a request message for IMS reregistration to the UEs being served by the failed P-CSCF. In this manner, the UE can continuously receive the service even though a failure occurs in the P-CSCF.

Abstract:
A method for sharing user profile information includes transmitting a session initiation message including profile information of a first user of the terminal to a communication network server based on a sharing level for the first user's profile information, receiving a response message responsive to the session initiation message from the communication network server or a corresponding terminal, storing or displaying profile information of a second user of the corresponding terminal, if the response message includes the profile information of the second user, and performing a call with the corresponding terminal. A terminal includes a controller configured to transmit a session initiation message including profile information of a first user of the terminal to a communication network server based on a sharing level setting on the first user's profile information, receive a response message responsive to the session initiation message, when the response message includes profile information of a second user of the corresponding terminal.
Abstract:
A method is provided for communication between a UE and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority. The MAC-PDU including the first and second fields is transmitted to the Node B. Grant information is received from the Node B. Data is transmitted to the Node B based on the grant information and the priority. One amount of data in the second field corresponds to one queue ID in the first field.

The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
Abstract:
An image sensor includes a photoelectric converter to generate charges in response to incident light and to provide the generated charges to a first node, a transfer transistor to provide a voltage of the first node to a floating diffusion node based on a first control signal, a source follower transistor to provide a voltage of the floating diffusion node as a unit pixel output, a correlated double sampler (CDS) to receive the unit pixel output and to convert the unit pixel output into a digital code. The first control signal having first, second, and third voltages is maintained at the second voltage in a period between when the voltage of the first node is provided to the floating diffusion node and when the CDS is provided with the voltage of the first node as the unit pixel output.
