Abstract: A traffic flow processing method, and apparatus. A terminal device receives first policy information from a session management network element, wherein the first policy information includes a first processing method for an uplink traffic flow. In response to the terminal device meeting a first condition, a second processing method for the uplink traffic flow or a downlink traffic flow is determined. First notification information is sent to a user plane network element, wherein the first notification information is for notifying the user plane network element to determine a third processing method for the downlink traffic flow. After meeting the first condition, the terminal device sends the first notification information to the user plane network element, to assist the user plane network element in determining whether to update a steering mode of a corresponding traffic flow.

Abstract: Embodiments of the present invention provide a method for controlling an E-UTRA capability of UE, an apparatus, and a system, and relate to the communications field. After UE fails to register with an E-UTRAN in a visited network, a ping-pong effect occurring on the UE can be avoided by disabling an E-UTRA capability of the UE. The method includes: obtaining, by an MME in a visited network, first reason information indicating why UE fails to register with the visited network, obtaining first indication information corresponding to the first reason information, and sending the first indication information to the UE, so that the UE disables the E-UTRA capability of the UE according to the first indication information.

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: A communication method, an apparatus, and a system in which a first session management function entity based on information of a terminal group determines user plane function entities accessed by terminals in a terminal group, and the first session management function entity determines a target user plane function entity based on the user plane function entities, where the target user plane function entity is used to perform communication between terminals in the terminal group. According to the method, the terminals in the terminal group are redirected to a same user plane function entity, namely, the target user plane function entity, so that communication between the terminals in the terminal group is locally implemented in the target user plane function entity. This shortens a communication path, and reduces a communication latency.

Abstract: Embodiments of the present invention disclose a method, a related apparatus, and a system for recovering a called service of a terminal. The method includes: when a called request of a user terminal is received, querying an initial proxy-call session control function (P-CSCF) entity with which the user terminal currently registers; if it is detected that the initial P-CSCF is faulty, selecting an available P-CSCF and sending, to the available P-CSCF, a notification message that carries a redundancy identifier, where the redundancy identifier is used to instruct the available P-CSCF to trigger the user terminal to re-register with the P-CSCF; and when a registration complete message sent by the P-CSCF with which the user terminal re-registers is received, delivering the called request to the re-registered P-CSCF to bear a called service of the user terminal.
