Abstract: A method in which a delegated client sends a request message containing operation information, a delegated client identity (ID), and a delegating client ID at the time of sending an operation request to a target system. The target system receives the request message and delegation-authorizes the delegated client by examining whether the delegating client is authorized to perform the operation requested by the request message and also whether the delegating client has delegated the authority to perform the operation to the delegated client sending the request message using the delegating client ID included in the request message. A new header is provided which includes ID information of the delegating client in the request message. When receiving the request message, the target system performs a procedure for authenticating and authorizing not only the delegated client but also the delegating client using the delegating client ID.

Abstract: A method, user equipment, and system are provided which can open an ad-hoc Push-To-Talk (PTT) over Cellular (PoC) session for a call target group whose group identifier is managed in a remote network domain when the ad-hoc PoC session is opened. A PoC client requesting session initiation sends, to a first PoC server of a home network, a session INVITE message containing information of at least one group identifier. The first PoC server checks the group identifier information and sends a group list information request message to a second PoC server hosting a group identifier when identifier information of a network group other than the home network is included. The second PoC server acquires list information about a group in the request message and sends the information to the first PoC server.

Abstract: Call processing methods and apparatuses are provided in a Session Initiation Protocol (SIP) based network involving at least one Push-to-Talk (PTT) over Cellular PoC client and a reception side PoC server. The reception side PoC server receives an INVITE request including a Manual Answer Override (MAO) indication from a transmission side PoC server. The MAO indication is for establishing an auto-answer mode in a pre-established session. If a reception side PoC client has the pre-established session with the reception side PoC server, the reception side PoC server sends an OK response to the transmission side PoC server in response to the INVITE request. The reception side PoC server sends a communication connection request including the MAO indication to the reception side PoC client.

Abstract: A call processing system and method based on an answer mode of a Push-to-Talk over Cellular (PoC) user are provided. A data format is defined, which inserts an indicator indicating a manual answer override into a payload of a Real-time Transport Control Protocol (RTCP) in a format of a new data field. When a PoC communication requester instructs the MAO to perform PoC communication regardless of an answer mode of a reception side PoC user, an auto-answer mode is immediately executed without any procedure of checking the instruction. In addition, when the reception side PoC user establishes an early session with a home PoC server in its own PoC terminal, the call processing can be performed at a quicker speed.

The media information includes a parameter related to media stored in the PoC box.

Abstract: The present invention provides a method in which when receiving an invitation request to a new PoC session, a PoC client participating in multiple sessions for which a maximum limit is set determines whether it is now participating in the maximum number of sessions, the PoC client notifies a user that the maximum number of sessions are used if the maximum limit is reached, and releases one of an existing session or the last requested session according to user selection.

Abstract: A converged IP messaging client transmits a session establishment request for interactive message communication. When a converged IP messaging server receives the request, it determines whether a target client of the interactive message communication uses a converged IP messaging service. If not, the converged IP messaging server transmits the session establishment request to an IWF. If it is determined that the target client is an SM client, the IWF generates an interactive message communication request by transforming a format of the session establishment request into an SMS format and transmits the interactive message communication request to the SM client. If the IWF receives an acceptance response from the SM client in response to the interactive message communication request within an effective response time, a session for the interactive message communication can be established between the converged IP messaging client and the SM client.

Abstract: A method and an apparatus for selecting a location platform for a user equipment to roam and a method for determining the location of the user equipment using the same. The method for selecting a location platform includes: checking a visiting network of the UE in response to a location request message transmitted from the UE which is roaming; and selecting a location platform to calculate a location of the UE by comparing positioning capability information of the checked visiting network and positioning capability information of a home network of the UE. According to such a method, it is possible to efficiently perform the positioning of the UE, regardless of the location of the UE, thereby improving the quality of the positioning service.
