Abstract:
A method, apparatus, and system for disaster recovery of an Internet Protocol (IP) Multimedia Subsystem (IMS), where the method includes: triggering a redundant Call Session Control Function (CSCF); obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities (IMPUs) in an IMS subscription from a network storage entity of a user; and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. Hence, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.
Abstract:
A method, an apparatus, and a system for processing registration backup data are disclosed. A Serving Call Session Control Function (S-CSCF) receives a request from a User Equipment (UE) and judges whether the request carries multi-registration information so as to decide whether to add multi-registration indication information into a Server Assignment Request (SAR) message sent to a Home Subscriber Server (HSS). The HSS performs operations according to whether the SAR message carries the multi-registration indication information, therefore avoiding unnecessary signaling interactions, reducing the signaling load, avoiding unnecessary data processing between the HSS and the S-CSCF, and saving system resources.

Abstract:
In a location change reporting method, a session management function entity receives from a mobility management entity information including location change information of UE in a first presence reporting area (PRA), an identity of the first PRA, and an identity of a PRA set that includes the first PRA. The session management function entity identifies, based on the identity of the PRA set and locally stored PRA subscription information, a subscription entity that subscribes to location change events of the UE in the PRA set, and sends the identity of the first PRA and the location change information of the UE in the first PRA to the subscription entity.
Abstract:
Embodiments of the present invention disclose a method, a network element, and a system for determining a target RAT. The method includes: receiving, by an access network element, access control information of a UE that is sent by a mobility management network element, where the access control information includes an identity of a PLMN and a radio access technology RAT allowed and/or a RAT not allowed by the PLMN; and determining, by the access network element, a target RAT for the UE according to the access control information.
Abstract:
Embodiments of the present disclosure disclose a service processing method, a PCRF, and a system. The method performed by the PCRF includes: obtaining service information of a service, where the service information includes a service identity; obtaining, according to user information and the service information, information indicating that the service requires QoS guarantee, and service chain information; when determining, according to the service chain information, that a network resource occupied by the service may be changed, sending the service identity and the information indicating that the service requires the QoS guarantee to a value-added service processor; receiving target service information, returned by the value-added service processor, of the service corresponding to the service identity; generating a first control policy according to the target service information; and sending the first control policy to a PCEF, so that the PCEF reserves a first network resource according to the first control policy.
Abstract:
Embodiments of the present invention provide a method, an apparatus and a system for processing charging information, wherein the method includes: a mobility management device acquires a PLMN identifier corresponding to a network name displayed by a user equipment; transmits the PLMN identifier corresponding to the network name displayed by the user equipment to a call detail record information generating device, so that user call detail record information generated by the call detail record information generating device includes the PLMN identifier corresponding to the network name displayed by the user equipment; therefore, a charging device can charge the user according to the network name displayed by the UE included in the user call detail record information generated by the call detail record information generating device, thereby ensuring accuracy of the charging the user, and enhancing user experience.
