The present invention discloses a called service processing method, a mobility management entity, and a home subscriber server. The method includes: generating, by an MME, VOPS capability indication information according to a faulty state of a PGW after determining that the PGW in which UE is located is faulty, where the VOPS capability indication information is used to indicate that a network in which the UE is located does not support VOPS; and sending, by the MME, the VOPS capability indication information to an HSS. According to the called service processing method, the mobility management entity, and the home subscriber server provided in embodiments of the present invention, a called service is not affected after a PGW is faulty.

Called service processing method, mobility management entity, and home subscriber server

A communication method includes: sending, by an MME, a bearer setup request message to an eNodeB, where the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message, sending, by the MME, an indication message to the user equipment, where the indication message is used to indicate that a voice over VoIMS of the user equipment is unavailable. When setup of a voice bearer of a VoLTE call fails, the user equipment is notified that a VoLTE is unavailable, so that the user equipment can be prevented from continuing attempting to initiate the VoLTE call and exacerbating cell congestion.

Communication method, device, and system

The present invention discloses a method and an apparatus for obtaining a neighbor relationship between network nodes, and a network device. The method includes: receiving a message sent by a network node; and parsing the message, to obtain a neighbor relationship between at least two network nodes involved in the message. The present invention further discloses a corresponding apparatus for obtaining a neighbor relationship between network nodes, and network device. According to the message sent by the network node, a core network learns the neighbor relationship between network nodes, and efficiency of performing a service between neighboring network nodes may be improved by using the neighbor relationship.

Embodiments of the present invention relate to the field of communications, and provide a method, a node, a mobile terminal and a system for identifying a network tethering behavior. The method includes: receiving, by a gateway general packet radio service support node (GGSN), an Internet protocol (IP) packet sent by a to-be-networked device and forwarded by a mobile terminal; acquiring a time to live (TTL) value in the IP packet; determining whether the acquired TTL value is different from a specified TTL value; and if yes, determining that the to-be-networked device performs a network tethering behavior. Further provided are a corresponding gateway general packet radio service support node, mobile terminal and system. The present invention improves accuracy of identifying a network tethering behavior and expands a range of applicable scenarios for identifying a network tethering behavior.

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.

Embodiments of the present invention provide a method for controlling UE to access a communications network of a high-speed moving vehicle, a core network control plane node device, a base station, UE, and a communications system. The method includes: determining that UE accessing the communications network is first-type UE, allocating a temporary identifier that includes a first sequence to the UE, and sending the temporary identifier to the UE, where when the UE accesses a public network, the first sequence is used to instruct the base station to transfer the UE to the communications network. In the embodiments of the present invention, user experience of the UE is improved.
