Patent number: 8295158Abstract: A method of session processing in the Internet Protocol (IP) Multimedia Subsystem (IMS) comprises: Interrogating-Call State Control Function (I-CSCF) accessing the Home Subscriber Server (HSS) to query the registration location of the called user, the I-CSCF sending the Session Initiation Protocol (SIP) request to the Serving-Call State Control Function (S-CSCF) based on the response of the HSS; when the response time of the S-CSCF to the SIP request sent from the I-CSCF has expired, the I-CSCF re-selecting the S-CSCF, and sending the SIP request to the S-CSCF. And an Interrogating-Call State Control Function is provided. According to the present invention, if the S-CSCF returned by the HSS to process the unregistered service of the IMS user does not responded because of the device failure or communication interruption or the like, the I-CSCF can re-select other S-CSCF to process the unregistered service of the IMS user, so as to improve the quality of service and to increase the satisfaction of user.Type: GrantFiled: February 29, 2008Date of Patent: October 23, 2012Assignee: Huawei Technologies Co., Ltd.Inventors: Changlin Li, Fenqin Zhu, Jianguo Zhao, Jing Wang, Xiaoyan He

Publication number: 20100195610Abstract: A method for improving Broadcast (BC) services includes the following steps: a Proxy-Call Session Control Function (P-CSCF) determines that a received service layer message is a BC service request; the P-CSCF sends a resource reservation instruction to a resource reservation processing entity, instructing the resource reservation processing entity to reserve shared resources. A device for improving BC services is also provided. By using the present invention, when a user initiates a BC service request, the P-CSCF sends an instruction to the resource reservation processing entity according to the BC service request of the user, instructing the resource reservation processing entity to reserve specific network resources. Because the user may watch only one channel at the same time, these resources may be shared by channels in the service package, thus saving network resources.Type: ApplicationFiled: April 9, 2010Publication date: August 5, 2010Inventors: Jianfeng ZHONG, Xiaoyan He
