摘要:
A method, system, and device for providing a service in the field of communications technologies are provided. The method includes the following steps. A terminal acquires a network instruction. The terminal initiates a call in a Circuit Switched (CS) domain according to the network instruction. The CS domain provides a service according to the received call from the terminal. The system includes a delivery device, user equipment (UE), and a device for providing a service. The UE includes an acquisition module and a processing module. By providing a network entity with enhanced functions (for example, an enhanced Visit Mobile Switch Center (VMSC) and an enhanced Proxy Call Session Control Function (P-CSCF)), the terminal is capable of providing an emergency call service and a monitoring service for a terminal user when a session is established by using an Internet Protocol (IP) Multimeda Subsystem (IMS) CS Control Protocol (ICCP) signaling.

A method, a system, and an apparatus for creating a Content-on-Demand (CoD) service are disclosed herein. The method includes receiving a Session Initiation Protocol (SIP) service request sent by a User Equipment (UE); converting the SIP service request into a Real-Time Streaming Protocol (RTSP) service request, and sending the RTSP service request to a server; receiving an RTSP service response sent by the server; and converting the RTSP service response into a SIP service response, and sending the SIP service response to the UE to create the CoD service between the UE and the server.
摘要:
The present invention discloses a communications network system including more than one type of communications network and a centralized subscriber database connected with the more than one type of communications network. The centralized subscriber database is able to process calls accessed via a communications network based on the subscriber data and send back the processing result of the calls to the communications network, which will re-route the calls based on the processing result thereof. Based on the above communications network system, this invention also discloses methods for flexible number plan, various simple services, smooth transfer of PHS subscribers to a 3G network, and short message communications based on flexible number plan.

A method for making awareness of occurrence of a supplementary service, a Voice Call Continuity service control entity and a media gateway control entity are disclosed. With the method, a Voice Call Continuity service control entity and/or a user may make awareness of the occurrence of a supplementary service in an IMS-based network architecture. The method includes: obtaining a notification signaling notifying that a user performs a supplementary service by at least one of the Voice Call Continuity service control entity or an opposite end of a call, and making awareness of occurrence of the supplementary service according to the notification signaling. With the method, functions of the Voice Call Continuity service control entity may be improved, so that the Voice Call Continuity service control entity may receive notification signaling notifying that a user performs a supplementary service, and to resolve the notification signaling, and to update the call attribute of the user.
摘要:
A thermal barrier coating composition is provided. The composition has a base oxide, a primary stabilizer, and at least two additional cationic oxide dopants. Preferably, a pair of group A and group B defect cluster-promoting oxides is used in conjunction with the base and primary stabilizer oxides. The new thermal barrier coating is found to have significantly lower thermal conductivity and better sintering resistance. In preferred embodiments, the base oxide is selected from zirconia and hafnia. The group A and group B cluster-promoting oxide dopants preferably are selected such that the group A dopant has a smaller cationic radius than the primary stabilizer oxide, and so that the primary stabilizer oxide has a small cationic radius than that of the group B dopant.

摘要:
A thermal barrier coating composition comprising a base oxide, a primary stabilizer oxide, and at least one dopant oxide is disclosed. Preferably, a pair of group A and group B defect cluster-promoting oxides is used in conjunction with the base and primary stabilizer oxides. The new thermal barrier coating is found to have significantly lower thermal conductivity and better sintering resistance. The base oxide is selected from the group consisting of zirconia and hafnia and combinations thereof. The primary stabilizing oxide is selected from the group consisting of yttria, dysprosia, erbia and combinations thereof. The dopant or group A and group B cluster-promoting oxide dopants are selected from the group consisting of rare earth metal oxides, transitional metal oxides, alkaline earth metal oxides and combinations thereof. The dopant or dopants preferably have ionic radii different from those of the primary stabilizer and/or the base oxides.

A method, system and apparatus for providing access mode selection to multimode terminal are disclosed. After selecting an access mode according to a certain policy, a routing decision entity correspondingly instructs a routing execution entity to perform a call connection in the selected access mode. The method for providing access mode selection to multimode terminal includes the following steps: (1) when establishing a registration connection, a terminal notifies related information of a current access network type to a network side; and (2) when performing a call connection to a called party, a routing decision entity on the network side selects the access mode and correspondingly instructs a routing execution entity to perform the call connection according to the related information and the selected access mode.
摘要:
A method and a system for maintaining session continuity, in which the system includes a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establish a session with the second user. The method further includes that, during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When access address or access technology of the terminal changes, or even the terminal changes during a session, the method and the system can logically replace the connection before the handover with a new connection to ensure the session continuity.
