Abstract:
Embodiments of the present invention disclose a security control method for an eUICC, including: verifying, by an embedded integrated circuit card eUICC, whether a subscription manager-secure routing SM-SR entity is authorized to manage the eUICC; and if yes, establishing, by the eUICC, a secure transmission channel with the SM-SR entity, where the secure transmission channel is used for management interaction of the eUICC. The embodiments of the present invention further disclose an eUICC. Security of the eUICC can be ensured by using the present invention.
Abstract:
A method and apparatus for service control in which a service centralization and continuity application server (SCC AS): receives a first SIP message for establishing an IMS centralized service session; receives early session media information; and sends a second SIP message carrying the early session media information to a media gateway control device. The early session media information is carried in the second SIP message in a form of regular session media information, thus the media gateway control device uses an existing circuit switched bearer to transmit early session media to a first user equipment. The existing circuit switched bearer is established under control of the media gateway control device for a session between the first user equipment and a third user equipment. The SCC AS receives an off-hook signal from the second user equipment, and sends the regular session media information to the media gateway control device.
Abstract:
The present invention discloses a mobility management method, a serving GPRS support node or mobility management entity (SGSN/MME), and a terminal to solve the problem of setting or dynamically modifying the mobility management frequency of a particular terminal among numerous terminals. The technical solution of the present invention includes: obtaining subscription data of a terminal, where the subscription data carries periodic update (RAU/TAU) setting information; obtaining a periodic update timer of the terminal according to the periodic update setting information; sending the periodic update timer of the terminal to the terminal; and setting a value that is a little longer than the periodic update timer of the terminal as a mobile reachable timer for monitoring the periodic update of the terminal. The embodiments of the present invention may be applied in low-mobility machine-type communication.
Abstract:
A management method for an embedded universal integrated circuit card includes: sending, by a subscription manager-secure routing SM-SR entity, a push request that includes a trigger message and at least one user identity to a public land mobile network PLMN/push server, so as to instruct the PLMN/push server to push the trigger message to a target embedded universal integrated circuit card eUICC indicated by the at least one user identity, where the trigger message is used to trigger the target eUICC to initiate communication with the SM-SR entity; establishing, by the SM-SR entity, a communications connection to the target eUICC; and performing, by the SM-SR entity, a management operation on the target eUICC by using the communications connection. The embodiments of the present invention further disclose a related device. In the present invention, batch management can be performed on eUICCs, which improves management efficiency.
Abstract:
The present invention is applicable to the field of communications technologies, and provides an method, the method includes: when a CS service and PS service of a local LTE single-card dual-standby multi-mode terminal are concurrent, detecting, by a local LTE single-card dual-standby multi-mode terminal, whether a peer communication terminal that is performing voice communication with it is in a voice silent period; when detecting that the peer communication terminal is not in the voice silent period, receiving, by the local LTE single-card dual-standby multi-mode terminal, downlink data in an LTE system, and suspending, by the local LTE single-card dual-standby multi-mode terminal, sending of uplink data in the LTE system at the same time; and when detecting that the peer communication terminal is in the voice silent period, sending the uplink data and receiving the downlink data, by the local LTE single-card dual-standby multi-mode terminal, in the LTE system.
Abstract:
Embodiments of the present invention disclose a method for a single card dual standby user equipment to camp on a network and a user equipment, so as to reduce power consumption of a user equipment. The method in the embodiment of the present invention includes: when a circuit switched domain CS domain of a UE camps on a second-generation mobile communications technology 2G/third-generation mobile communications technology 3G network and a packet switched domain PS domain camps on a long term evolution LTE network, executing, by the UE, a routing area update process of the PS domain of the 2G/3G network if the UE meets a preset first condition, so as to make the PS domain of the UE camp on the 2G/3G network; and after the PS domain of the UE camps on the 2G/3G network, turning off an LTE radio frequency unit.
Abstract:
Embodiments of the present invention provide a method and an apparatus for measuring an antenna space correlation, and a terminal device. The method includes: measuring and acquiring, by a terminal device when it is in measurement mode, measurements related to antenna space correlation measurement, and sending the acquired measurements related to the antenna space correlation measurement to a test instrument. After entering a measurement mode, the terminal device measures and calculates measurements required for the antenna space correlation measurement, and sends a measurement result to the test instrument. An antenna space correlation result of the terminal device can be calculated by using a parameter displayed on the test instrument, thereby providing a basis for an antenna engineer and a hardware design engineer to optimize antenna design.
