Description
Technical field
The present invention relates to wireless communication technology field, determine that terminal will leave the network coverage particularly to one
The method and apparatus in region.
Background technology
In LTE (Long Term Evolution, Long Term Evolution) system, take is that network concentrates control
The mode of system, i.e. the up-downgoing data of UE (subscriber equipment) are transmitted the most under the control of a network and connect
Receive.Communication between UE and UE, is forwarded by network and controls.Do not deposit between UE and UE
At direct communication link, UE does not the most allow to send upstream data voluntarily, sees Figure 1A.
D2D (Device-to-Device, device-to-device), i.e. subscriber equipment leads directly to technology, refers to neighbouring
Subscriber equipment can in short range by the way of direct connected link carries out data transmission, it is not necessary to logical
Cross Centroid (i.e. base station) to forward, as shown in Figure 1B.
In 3GPP (3rd Generation Partnership Project, 3G (Third Generation) Moblie standardization body),
D2D includes following two big classes close to service:
D2D finds: UE uses E-UTRA to confirm that another one UE is in its vicinity.Such as, D2D
UE can use this service to carry out the taxi of finding nearby, find friend etc. in its vicinity；
D2D communicates: UE close to each other, by directly setting up link between two UE, so will
Originally the communication link transmitted by network is converted into the DCL of this locality, saves substantial amounts of bandwidth
And network efficiency；Or two UE close to each other, it is possible to use direct link communication obtains stable height
The communication service that speed is cheap.Usually carry out under network controls or auxiliary close to communication for service,
ENB (evolution base station) possibly even can be for carry out the dynamic Resources allocation of UE close to communication for service.
D2D communicates and is divided into two kinds of Linktypes at present:
D2D link: refer to the link directly communicated between equipment and equipment；
D2N link: the link communicated between equipment and network node.
Participate in D2D find/UE of communication is divided into two kinds of roles:
D2D sends UE: i.e. send the UE of D2D discovery/communication information；
D2D receives UE: i.e. receives D2D and sends the UE of discovery/communication information that UE sends.
In 3GPP Rel-12, introduce the interface carrying out direct interaction between UE and UE, be referred to as
PC5 interface.
D2D find and communication technology on the basis of, UE can by Relay (relaying) by the way of and
Network carries out data transmission.
UE is referred to as UE-to-Network Relay (also referred to as by the way of Relay UE communicates with network
For UE-to-NW Relay), as shown in Figure 1 C.UE2 outside the network coverage in order to communicate with network,
Using UE1 as Relay node, forwarded the uplink and downlink signals of oneself by UE1.Wherein, UE1 and UE2
Between communication by D2D communication realize, realized by cellular communication between UE1 and network.
Relay UE: provide the Relay UE of service for other UE.
Remote UE: the UE outside network coverage, need to be realized and between network by Relay node
The UE of communication.
UE likely leaves network's coverage area (i.e. entering off-grid state) mobile when, if UE
Currently carry out data transmission, data interruption and loss of data can be caused after leaving network's coverage area.
Need to leave network's coverage area if UE can obtain in advance, then can be prepared minimizing in advance and cause
The situation of data interruption and loss of data occurs.But there is presently no one and determine that terminal will be left in advance
The scheme of network's coverage area.
In sum, there is presently no a kind of scheme determining that terminal will leave network's coverage area in advance.
