Embodiments of the invention relate to the communications field, and provide a key generation method, device, and system. The method includes: after receiving a first command, obtaining, by UE located in a first-standard network, a type identifier of a second-standard network that needs to provide a service to the UE, where the first command is a service request response message, or a handover command, or any message in an air interface secure activation process; determining, by the UE, an access key according to the type identifier of the second-standard network, a key of the first-standard network, and a NAS count of the first-standard network by using a preset key derivation algorithm; and generating, by the UE, an AS key of the second-standard network according to the access key. The present invention can resolve problems of relatively long total communication latency and relatively high communication load of a heterogeneous network.

A wireless communication device (WCD), network node, and methods for determining whether to steer traffic from a first access point to a second access point according to an access network selection policy. The WCD obtains at least one input parameter for use in an algorithm that is part of the access network selection policy, obtains a random value, and determines whether to steer traffic from the first access point to the second access point based at least in part on the at least one obtained input parameter and the obtained random value. The at least one input parameter may be determined by the network node and signaled to the WCD. The network node may signal an indication to the WCD to cause the WCD to apply a random value when determining whether to steer traffic in accordance with the access network selection policy.

An operation method of a communication node in a millimeter-wave based communication system may comprise when a first communication path between the second base station and the terminal connected to the first base station is not established, transmitting a radio resource control (RRC) request message requesting establishment of the first communication path to the second base station via the first base station; receiving an RRC response message from the second base station via the first base station, the RRC response message being a response to the RRC request message; and establishing the first communication path based on the RRC response message.

The present invention discloses a processing method and device for reselecting or switching UE from a TD-SCDMA system to a TD-LTE system. The method includes: receiving, by a PGW, a modify bearer request message sent by an SGW; obtaining, by the PGW, an S5/S8 interface resource in current bearer context information, updating the bearer context information according to the modify bearer request message, and obtaining an S5/S8 interface resource in the updated bearer context information; when the PGW determines that the S5/S8 interface resource changes according to the S5/S8 interface resource in the updated bearer context information and the interface resource in the current bearer context information, sending back, by the PGW, a modify bearer response message carrying the S5/S8 interface resource in the updated bearer context information to the SGW, for enabling the SGW to update the bearer context information according to the modify bearer response message. In the present invention, the scenarios supported by the existing protocol are perfected, and support is provided for reselecting or switching the UE from the TD-SCDMA system to the TD-LTE system and processing under scenarios in which the S5/S8 interface and the Gn/Gp interface are in different networks.

This application discloses a network transfer method, an apparatus, and a device, and relates to the communications field. The method includes: receiving first extended steering of roaming SOR information sent by a network side device; in a case that the terminal device supports the a capability of negotiating extended SOR, determining a priority of an ongoing service based on the first extended SOR information; and performing a transfer operation matching the priority of the ongoing service, where the transfer operation is an operation that the terminal device transfers from a currently camping public land mobile network PLMN to a target PLMN.

A service transfer method and apparatus, and a service transfer processing method and apparatus relate to the field of mobile communications, are applied to a service transfer technology, and can improve utilization of network system resources. The method comprises: acquiring, by a UE, first information that is used to instruct the UE to perform service transfer to a wireless local area network (WLAN) access point; performing service transfer according to the first information; and sending a service transfer result to a 3rd Generation Partnership Project (3GPP) access point that serves the UE.

In a cellular communications network, user equipment connected to a base station, the active mode handover behavior of the base station for selecting handover targets is set to be different from idle mode reselection. The MME provides its eNodeBs with supplemental information about other PLMNs which can be considered for handover in accordance with dynamic criteria such as the time, location, subscriber group, etc to allow dynamic handover to other PLMNs in accordance with the commercial agreements.

Embodiments of the present application relate to the technical field of wireless communications, and in particular, to a method and a device for performing carrier scheduling, which are used to perform scheduling for an unlicensed carrier. In the embodiments of the present application, a terminal performs uplink channel measurement in an uplink subframe or an uplink measurement time period of an unlicensed carrier, to determine uplink channel quality information, and/or performs downlink channel measurement in a downlink subframe of the unlicensed carrier, to determine downlink channel quality information; and the terminal notifies a network side device of the determined uplink channel quality information, and the network side device determines, according to the received uplink channel quality information, whether to perform uplink scheduling on the terminal on the unlicensed carrier, and the terminal notifies the network side device of the determined downlink channel quality information, so that the network side device determines, according to the received downlink channel quality information, whether to perform downlink scheduling on the terminal on the unlicensed carrier. In this way, scheduling is implemented for the unlicensed carrier, thereby further improving system performance.

A method for controlling the activity of a base station entity of a first type in a mobile communication network via a mobile device having a communication link to a base station entity of a second type includes: sending, by the mobile device, a connection request to the base station entity of the second type, the connection request being related to a request of the mobile device to have a communication link with the base station entity of the first type while the base station entity of the first type is in its second operational mode; and activating the first operational mode of the base station entity of the first type and establishing the communication link between the mobile device and the base station entity of the first type established.
