The method includes: a home device sends operation information to a server, where the operation information is used to indicate an operation performed by a user on the home device; and after receiving the operation information from the home device, the server determines a target account, where the target account is one of accounts associated with the home device, and sends a notification message to a target terminal device, where the notification message includes status information used to indicate a status of the home device, the status information is related to the operation information, and the target terminal device is a terminal device on which the target account is logged in.
Abstract:
The embodiments of the present application discloses a circuit switched fallback method, a UE, an MSC, and an MME. The method includes: sending, by a UE to an MME, a request message for requesting to perform CSFB; receiving, by the UE, a switch command sent by an eNodeB; releasing or holding a default CS call of the UE after the UE switches to the CS domain according to the switch command, where the default CS call is generated by the UE according to the switch command; and by using an MSC, initiating, by the UE, a CS call or receiving a CS call. According to the circuit switched fallback method, the UE, the MSC, and the MME in the embodiments of the present application, circuit switched fallback can be implement in a manner of switching by a UE from a PS domain to a CS domain, and reduce a delay.
Abstract:
The present invention discloses a packet-switched network access method, a WLAN access system and a user equipment. The packet-switched network access method includes: receiving indication information sent by a user equipment attached to a WLAN or sent by an HSS/AAA, where the indication information is used to indicate whether the user equipment is capable of providing information of accessing a PS network; and determining, according to the indication information, whether establishing a PDN connection after authentication is successful or after a layer 3 message sent by the user equipment is received, so that the user equipment accesses a PS network by using the WLAN.

Abstract:
The present invention discloses a method and a device for handover to a serving network. The method includes: receiving a first Handover Request sent by a BSC/RNC; sending a second Handover Request to a target MME according to the first Handover Request, where the second Handover Request includes an IMSI and first information for determining a source SGSN so that the MME sends a Context Request message including the IMSI to the source SGSN and receives context information of a UE that corresponds to the IMSI and is sent by the source SGSN. Thereby avoiding a handover failure which is caused because the MSC server and the SGSN select different MMEs, and further synchronizing PS and CS handover processes, improving handover accuracy and efficiency, and enhancing user experience.
Abstract:
The present disclosure a service path changing method and apparatus, including: determining, by an MME, that a UE needs to be handed over from a first AG to a second AG; and instructing, by the MME, the UE to notify, according to bearer information used to perform service transmission between the second AG and the UE and assigned by the second AG, a service peer end that an IP address of the UE is changed from a first IP address assigned by the first AG to a second IP address assigned by the second AG. It is not required to add the first IP address assigned to the UE by the first AG into the IP address segment maintained by the second AG, and it is unnecessary to change routing information of a router in a PDN to route downlink data of the UE to the second AG.
Abstract:
Embodiments of the present invention disclose a method, a mobile switching center and a system for returning to a long term evolution network, which may prevent a UE which does not need to return to the LTE network from mistakenly returning to the LTE network. The method includes: receiving a first CSFB indication corresponding to a UE that is sent by a MME after the UE initiates CSFB, wherein the first CSFB indication is used for identifying that the UE needs to return to a LTE network after circuit service of the UE is finished; and sending, according to the first CSFB indication, a second CSFB indication corresponding to the UE to an RNC/BSC when the circuit service of the UE is finished, wherein the second CSFB indication is used for indicating that the RNC/BSC is to notify the UE of returning to the LTE network.
Abstract:
Embodiments of the present invention provide a method, device, and system for scheduling a data flow, which are used to improve the processing efficiency. A network side device marks a priority of a subsequent uplink and/or downlink data flow of a UE corresponding to a downlink data packet in the downlink data packet, and enables a downstream node to schedule an access network resource or air interface resource according to the priority. Therefore, a bearer does not need to be modified during the process of distinguishing different service flows and performing differentiation scheduling on different service flows, thereby reducing the workload and improving the processing efficiency.
Abstract:
Embodiments of the present invention provide a method for triggering data offload. The method includes: receiving, by a first network element from a home subscriber server HSS, information of a packet data network PDN connection, where the information includes offload indication information, and the PDN connection is established by a UE through a second access network; and obtaining, by the first network element, the offload indication information, and triggering, according to the offload indication information, processing of offloading a data flow in the PDN connection to a first access network. In the foregoing provided solution, the UE does not need to indicate, to the first network element, information that offloading is required for the PDN connection, and therefore the UE does not need to support an IKEv2 protocol. This lowers a requirement of the foregoing offload technology on the UE.
Abstract:
A method for a user equipment UE to access an evolved packet core network EPC includes: receiving, by an EPC access gateway connecting a wireless local area network WLAN to an EPC, a Dynamic Host Configuration Protocol DHCP request from the UE; and obtaining, by the EPC access gateway, subscription data of the UE according to a media access control MAC address of the UE in the DHCP request, and performing EPC access processing for the UE according to the obtained subscription data, where the obtaining subscription data of the UE according to a MAC address of the UE includes: obtaining the subscription data of the UE according to the MAC address of the UE and the MAC address of the UE and the subscription data of the UE that are correspondingly stored by a network device in an access authentication process.
