A method and apparatus used for a dual-network dual-standby terminal implementing service distribution are disclosed in the present document. The dual-network dual-standby terminal includes an application module, a first communication module and a second communication module. When a user of the dual-network dual-standby terminal initiates a Circuit Switched (CS) service, the application module selects the first communication module, and the first communication module performs communication through a 2G network; when a user of the dual-network dual-standby terminal initiates a Packet Switched (PS) service, the application module selects the second communication module, and the second communication module performs communication through a 3G network or a 2G network.

A method for obtaining an identifier of a new cell in a radio communication system is provided. The method includes receiving information associated with the new cell from a user equipment (UE), obtaining an evolved universal terrestrial radio access (EUTRA) cell global identifier (ECGI) of the new cell, if it is determined based on the information associated with the new cell that the new cell is not set as a neighbor cell, determining whether a public land mobile network (PLMN) identifier (ID) (PLMN ID) in the ECGI is included in a relation table including at least one of PLMN IDs and shared PLMN IDs, and receiving an identifier of the new cell from a server, if the PLMN ID in the ECGI is included in the relation table.

A base station including a plurality of antenna assemblies in a mobile communication system divides an ultra wideband into a plurality of unit-bands (UBs), forms a plurality of beams by the plurality of antenna assemblies, groups a plurality of beam component carriers distinguished by the plurality of UBs into beam component carriers that belong to the same UB to operate the grouped beam component carriers as a plurality of cells, and configures one cell among the plurality of cells as a cell for movement of a terminal.

The present disclosure provides a terminal that comprises: a call setup unit, for carrying out a voice call setup procedure on the first communication network if a call request is received when data service is being carried out by using the first communication network; an interaction unit, for receiving circuit resource information of the second communication network required for establishing voice service corresponding to the call request; a processing unit, for sending an answer response to a mobility management entity, disconnecting the data service of the first communication network according to the received voice fallback information, and establishing voice service of the second communication network by using the received circuit resource information, if it is detected that an answer button of the terminal is selected after the voice call setup procedure is completed. Correspondingly, the present disclosure also provides a mobility management entity, a mobile switching center, a service processing method and a service processing system. By means of the present technical solution, whether to carry out a circuit domain fallback is determined according to whether a user answers a call, so that the data service is not affected when the user does not answer the call.

The present disclosure generally relates to the field of Radio Resource Control (RRC). More specifically, the present disclosure relates to techniques of supporting and initiating RRC connection establishment in a wireless communication network. A method embodiment relates to supporting RRC connection establishment in a wireless communication network and comprises setting up context information during a first RRC connection establishment procedure to establish a first RRC connection towards a radio access network element (200) of the wireless communication network implementing a first Radio Access Technology (RAT). The context information is associated with a wireless communication device (100) of the wireless communication network and is usable for a second RRC connection establishment procedure to establish a second RRC connection towards a radio access network element of the wireless communication network implementing a second RAT.

A data forwarding method includes: receiving, by a session management function network element, information about a first bearer in a first network from an access and mobility management function network element; and sending flow information of a first flow in a second network and forwarding information to the access and mobility management function network element. The flow information indicates a flow for data forwarding, and the forwarding information is used for forwarding the first flow to a tunnel corresponding to the first bearer.

In one example, an apparatus is provided that includes a processor configured to receive, in a first wireless network, an identifier of a base station in a second wireless network, and to determine an identity of a first device in the second wireless network. The apparatus is configured to transmit the identifier of the base station to the second wireless network.

A method for wireless communication is described. The method includes receiving a signal from a short-range transmit device using a first communication technology. The signal indicates proximity and characteristics of a remote device that uses a second communications technology. The method also includes configuring a controller according to the signal for communications with the remote device using the second communications technology.

One disclosure of the present specification provides a method by which a UE performs sidelink communication. The method may comprise the steps of: performing sidelink communication on the basis of a first RAT; switching a RAT for the sidelink communication from the first RAT to a second RAT; performing the sidelink communication on the basis of the second RAT; and communicating with a base station on the basis of NR.

A handover control method, a network-side device, and a system are provided. The method includes: sending, by a first network-side device, a first handover request to a second network-side device, wherein the first network-side device is applied to a first network, and the second network-side device is applied to a second network, and a terminal is attached to the first network, and the first handover request contains first terminal information of the terminal, and the first terminal information is used for configuring a resource prepared for handover for the terminal to hand over to the second network when the second network-side device determines that the first terminal information meets a predetermined condition for initiating a handover operation.
