Abstract: Embodiments of this application relate to the field of communications technologies, and disclose a service setup method and a device, to resolve a problem that a service cannot be normally executed. The method includes: receiving, by an access network device, a first setup request; sending a first setup response to a first core network device or a first service application server, where the first setup response is used to indicate that the access network device accepts the first setup request; when radio channel quality of a first cell of a first network in which UE is located does not satisfy a service requirement of a first service carried in the first setup request, handing over the UE to a second cell of the first network, or handing over the UE to a third cell of a second network.

Abstract: This disclosure provides a service communication method and a device, and relates to the field of communications technologies. A solution carried out by access network device is: receiving, from a core network device, a bearer setup request message for requesting to set up a bearer for a service, where the bearer setup request message carries a service requirement of the service; setting up the bearer for the service; sending a bearer setup response message to the core network device, where the bearer setup response message is used to notify the core network device that the access network device has set up the bearer for the service; and sending, a bearer deletion request message to the core network device when the access network device determines that radio channel quality provided by the access network device does not meet the service requirement.

Abstract: A method where a data analytics network element may determine a background traffic transmission data analysis result of a first terminal device based on target background traffic transfer policies of another terminal device (that is, a second terminal device), and where the data analytics network element may further enable a first policy control network element to determine a background traffic transfer policy of the first terminal device. Therefore, the background traffic transfer policy of the first terminal device is determined by the first policy control network element with reference to the other terminal devices.

Abstract: Embodiments of this application provide a session management method, an interworking method between different systems, and a network apparatus. The session management method includes: when establishing a guaranteed bit rate (GBR) flow of a terminal device in a first communications system, determining, by a session management network element in the first communications system, that the GBR flow is a GBR flow required for handing over the terminal device from the first communications system to a second communications system; and establishing, by the session management network element for the GBR flow, a session context corresponding to the second communications system. The methods and the network apparatus are used to resolve a technical problem of resource waste existing in a handover method in the prior art.

Abstract: Embodiments of the present invention relate to the field of communications technologies and disclose a data processing method, apparatus, terminal, mobility management entity, and system, so as to reduce data transmission resources and avoid bringing an economic loss to a user. The method in the present invention includes: detecting a status of a data switch of a terminal, where the status includes a disabled state or an enabled state; and sending, by the terminal, a public data network PDN disconnection request to a mobility management entity MME after the status of the data switch is changed from the enabled state to the disabled state, where the PDN disconnection request carries information about a data bearer corresponding to a data domain access point name APN, and the PDN disconnection request is used to trigger the MME to delete the data bearer corresponding to the APN.

Abstract: A voice roaming method, a mobility management network element, and an access network element are provided. When determining that a terminal is a roaming terminal and supports a voice over Long Term Evolution (VoLTE) service in a roaming network, the mobility management network element prohibits a single radio voice call continuity (SRVCC) function of the terminal, and notifies the access network element, so that the access network element prohibits triggering an SRVCC procedure for the terminal.

Abstract: In a network handover method, after UE located on an LTE network initiates a request message that requests CSFB, an MME instructs an enodeB to move the UE from the LTE network to a 2G or 3G network, and requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network for the CSFB, so that the 2G or 3G network allocates a CS domain resource to the UE. Further, by determining that an IMS voice session does not exist, it is identified that the handover of the UE from the LTE network to the CS domain of the 2G or 3G network is triggered by the CSFB, so as to ensure that handover from the LTE network is properly performed.

Abstract: The present invention discloses a network handover method, where in a process of implementing circuit switched fallback, handover from an LTE network to a 2G or 3G network is triggered, so that UE can be directly handed over from the LTE network to a CS domain of the 2G or 3G network, and the network or the UE uses a session generated in the process in which the called party is handed over from the LTE network to the CS domain of the 2G or 3G network. Therefore, a common called procedure does not need to be performed after the UE is handed over from the LTE network to the 2G or 3G network, thereby shortening time for which a user waits before the voice session is connected.

Abstract: The present invention discloses an LTE network selection method. In a process of implementing CSFB combined registration, an MME of a Long Term Evolution LTE network sends a location area identity LAI to UE, where the LAI includes a PLMN identity of the LTE network, so that after a circuit switched fallback-based voice session ends, the UE preferably returns to the LTE network according to the PLMN identity.
