20080248762 | METHOD FOR MANAGING ONE OR MORE MEDIA TYPES SUPPORTED IN A POC SESSION, AND A POC SYSTEM AND A POC USER EQUIPMENT FOR IMPLEMENTING THE SAME - A PoC system, method, user equipment and server used for managing one or more media types supported in a PoC session opened between a PoC server and one or more PoC clients is provided. When at least one PoC client is engaged in a Open Mobile Alliance (OMA) Push-to-talk (PPT) over Cellular (PoC) multimedia communication service and is to be withdraw from a PoC session in which the PoC client is participating, a PoC server identifies and stores information about one or more media types that were negotiated to be usable between the corresponding PoC client and the PoC server when the corresponding PoC client joined the PoC session. Next, when the number of PoC clients using the identified one or more media types among remaining PoC clients participating in the PoC session is one or less, the PoC server determines that the identified one or more media types is no longer needed for the corresponding PoC session, and corrects the PoC session so as to not use the identified one or more media types. Accordingly, when the one or more media types will not be received by any PoC client in the PoC session the use of the one or more media types in the PoC session is discontinued, so that it is possible to prevent a transmission error of the corresponding one or more media types and to save resources allocated to the corresponding one or more media types. | 10-09-2008 |

To this end, a REFER BYE message is used to terminate the PoC session while keeping the pre-established session maintained. The REFER BYE message must include information, such as pre-established session parameter information, a session ID, etc. In order to obtain the session parameter information, when the PoC session is opened by means of the pre-established session, a specified condition is determined in the terminating-side PoC client and a PoC server, and the pre-established session parameter information is stored in each PoC client and a PoC server acting as a participating PoC function according to a result of the determination. Also, the REFER BYE message is transmitted from the PoC client to the PoC server, and the PoC server receives the REFER BYE message, checks the contents of a header in the received message, and terminates the PoC session while keeping the pre-established session maintained when a specified condition is satisfied. | 10-09-2008 |

The method includes transmitting by a previous H-SLP a report message informing that a target terminal is in a roaming state during the triggered location service to an H-SLP of the target terminal or the target terminal. The H-SLP of the target terminal selects a new V-SLP based on a location identifier (LID) received from the target terminal, and the H-SLP provides the V-SLP with an ID of the target terminal, a positioning method of the target terminal (SET CAPABILITY), and the LID as the information on the network in which the target terminal currently exists. The newly selected V-SLP determines the positioning method and protocol used for the positioning with the target terminal by using the SET CAPABILITY, the newly selected V-SLP transmits its own IP address and the newly determined positioning method and protocol (POSMETHOD) to the H-SLP. The H-SLP transmits the IP address of the newly selected H-SLP and the new POSMETHOD to the target terminal, the target terminal transmits a positioning inducing message to the new V-SLP and calculates a location value by using the determined POSMETHOD, in such a manner that the triggered location service is maintained even though the target terminal is in a roaming state during the service by performing the step of selecting the H-SLP for calculating the location value of the target terminal without interruption. | 04-28-2011 |
