Description

-种D2D通信中的资源协商方法及设备 - The resource negotiation method and device types D2D communication

技术领域 FIELD

[0001] 本发明设及通信技术领域,尤其设及一种D2D通信中的资源协商方法及设备。 [0001] The present invention is provided and communications technologies, and in particular is provided an apparatus and method for resource negotiation D2D communication.

背景技术 Background technique

[0002] 物联网是指,通过部署具有一定感知、计算、执行和通信能力的各种设备,获取物理世界的信息,并通过网络实现信息传输、协同和处理,从而实现人与物、物与物的互联的网络。 [0002] Things means, by deploying a certain sensing, computing, communication capabilities and the implementation of various devices, and obtaining information about the physical world, and transmitting information through the network, and the cooperative processing, in order to achieve objects, things and interconnected network objects. 简而言之,物联网就是要实现人与物、物与物的互联互通。 In short, things is to achieve interoperability and objects, things and objects. 物联网的应用包括智能电网、智能农业、智能交通W及环境检测等各个方面。 Things applications include all aspects of the smart grid, intelligent agriculture, intelligent traffic W and environmental detection. D2D值evice-to-Device,设备对设备) 通信,作为物联网应用的一种,主要是实现两个设备之间的直接通信。 D2D value evice-to-Device, the device of the devices), as a networking applications, is to achieve direct communication between the two devices. D2D通信设及的技术包括:WPAN(WirelessPersonalAreaNetworkCommunicationTechnologies,无线个人局域网通信技术)、UWB扣ItraWideband,超宽带)、藍牙炬luetooth)、Wifi(无线宽带)等短距无线通信技术。 D2D communication design and technology include: WPAN (WirelessPersonalAreaNetworkCommunicationTechnologies, wireless personal area network communication technology), UWB buckle ItraWideband, ultra-wideband), Bluetooth, torch luetooth), Wifi (wireless broadband) and other short-range wireless communications technology.

[0003] 为加强移动运营商在物联网领域的控制权,已经有相关公司开展了在运营商的授权频段支持D2D应用的研究,并积极推动在知名标准组织3GPP立项,目的是使用运营商的授权频段来支持和实现D2D应用。 [0003] In order to strengthen the mobile operators control over the Internet of Things, we have related companies to carry out research in the authorized carrier band support D2D applications, and actively promote the well-known standards organization 3GPP project the aim is to use the operator's licensed bands to support and implement D2D application. 在运营商授权频段实现D2D通信,首要解决的问题就是, 在不影响现有蜂窝通信的情况下,如何进行设备发现、资源协商和资源分配。 Licensed band achieved D2D communication operators, the primary problem is that, without affecting existing cellular communications, how to conduct discovery, resource negotiation and resource allocation. 现有UWB系统提供一种设备发现的方法,因为UWB是一种完全分布式系统,所WUWB设备之间通过定期在超帖中发送信标帖来实现设备发现和资源协商。 Existing UWB system provides a method of device discovery, because UWB is a fully distributed system, implemented by device discovery resource negotiation and periodically sends a beacon in the tie between the posts in the super WUWB devices. 其中,一个UWB超帖,长度为65536yS,由256个MAS(MediumAccessSlot,媒介接入时隙)组成,每个MAS长度为256US。 Wherein a UWB Ultra signature, length 65536yS, 256 MAS (MediumAccessSlot, media access slots), each MAS length is 256US. 每个UWB 超帖的开头都是一个BP(信标周期,beaconperiod),每个信标周期可W包括若干个信标时隙化eaconslot),信标时隙的长度可W为85yS,而BP的最大长度可W为96个信标时隙。 Each UWB Ultra posts are beginning a BP (beacon period, beaconperiod), each beacon period W may comprise a plurality of beacon slots eaconslot), the length of beacon slots may be W is 85yS, and BP the maximum length W of 96 beacon slots.

[0004] 基于上述设备发现方法,现有技术中的资源分配方式包括;一种是预留资源的方式,就是为之预留资源的设备在预留资源内可W发送信息;另外一种就是竞争方式,即是在BP和上述预留资源外,采用竞争方式发送信息。 [0004] The method based on the above discovery, resource allocation of the prior art comprises; one is reserved resources embodiment, whom the device is reserved resources may be sent within W reserved resources; another is competitive manner, that is, outside the BP and said reserved resources, send a message in a competitive manner.

[0005] 因为设备在进行发现时,没有考虑发送信标帖的可用资源问题,在现有的蜂窝通信的资源上任意发送信标帖,该就会对已有的蜂窝通信造成干扰,即便设备能够实现发现, 但是也无法得知相互之间的资源预留情况,该就会导致设备在发现之后进行竞争资源占用,或者进行复杂的预留资源协商过程,直接应用到蜂窝通信环境中时效率较低;进一步的,如果信标帖中包含直接关于某个MS的预留信息,那么,就有可能存在资源预留冲突, 而需要进行复杂的冲突处理过程,也会导致设备之间资源协商的效率相对较低。 [0005] Since the device discovery is performed, without considering available resources to transmit a beacon posts, any post transmits a beacon, which will cause interference to the existing cellular communications in the cellular communication available resources, even if the device to achieve find, but can not know the resource reservation situation between each other, which will cause the device to compete footprint after discovery, or complex negotiation process to reserve resources, applied directly to the cellular communication environment efficiency lower; further, if the beacon post contains information about a reserved MS directly, then it is possible there is a resource reservation conflict, and the need for complex post-conflict processes, will lead to resource negotiation between devices the relatively low efficiency.

D2D通信双方,无论是否与基站失去连接,只要W主从方式进行通信,处于主地位的设备为主设备, 处于从地位的设备为从设备。 D2D communication parties, regardless of whether the connection is lost with the base station, as long as the main communication from W mode, the device is in the main position of the master device, slave device in position as a slave. 如果不W主从方式进行通信,D2D通信双方地位平等,则不区分主从设备。 If you do not communicate the main W, D2D communication from the way the two sides on an equal footing, not to distinguish between master and slave devices. 其中,主设备可W从蜂窝通信的基站侧或者其它主设备侧获取发送信标帖的可用资源位置信息,也可W自己定义信标帖可用资源位置信息,并可W根据需要把上述获取的、或者定义的信标帖可用资源位置信息发送给从设备;从设备可W从蜂窝通信的基站侧或者主设备侧获取信标帖可用资源位置信息,而不能自己定义信标帖可用资源位置信息。 Wherein W master device may acquire the position information of the available resources to transmit a beacon from the base station side posts or other cellular communication master device side, W can define their own beacon posts available resource location information, and W is required to obtain the above-described or beacon posts available resource location information defined sent from the device; device may W acquired beacon posts available resource location information from the base side or the master-side cellular communication, but can not define their own beacon posts available resource location information from . 主从设备在发送信标帖之前,都需要获取信标帖可用资源位置信息。 From the master device before transmitting a beacon posts, posts need to acquire beacon position information of the available resources.

[0032] 其中,在下述=种场景下,主从设备的定义标准可W为:(1)、所有D2D设备都能与蜂窝通信网基站连接的情况下,所有设备都可W从蜂窝通信基站侧获取信标帖可用资源位置信息,可是否选择主从式通信、W及在主从式通信中的主从地位,确定设备是主设备还是从设备;(2)、在有部分D2D设备与基站失去连接的情况下,与基站失去连接的设备可W是从设备,其它设备可W根据是否选择主从式通信模式,W及在主从通信模式中的主从地位,来确定主设备还是从设备;(3)、在所有D2D通信的设备都与基站失去连接的情况下, 可W按照一定的规则,选择部分设备作为主设备,比如选择信标时隙为〇、1或者其它时隙的设备作为主设备,并将剩余时隙对应的设备作为从设备。 [0032] wherein, in the following scene =, from the master device may define a standard for the W: the case (1), all devices can D2D communication network connected to the cellular base station, all devices from a cellular communication base station W side obtains beacon posts available resource location information, whether to select the master-slave communication, W, and the master-slave communication master from the position determination device is a master device or a slave device; (2), in part D2D device When the base station loses connection with the base station lost connection device may be W is a slave device, other devices may be W depending on whether the selected master-slave communication mode, W, and is determined from the position of the master-slave communication mode, the primary master or from equipment; (3), in the case where all the devices are lost D2D communication connection with a base station, according to certain rules may be W, the device selection section as a master device, such as selecting a beaconslot square, or other time slots 1 device as a master device, and the remaining time slot corresponding to the device as a slave device. 需要说明的是,除非经过预先设定,一个参与D2D通信的设备默认情况下为主设备; Incidentally, unless after a preset, the apparatus involved in a default D2D communication master device;

[0033] 信标帖可用资源位置:可位图化itmap)的形式示意出可W发送信标帖的资源位置; [0033] beacon location posts available resources: a bitmapped itmap) W can be in the form of a schematic illustrating the beacon transmission resource location posts;

[0034] 业务类型;用来标识信标发送设备要求的业务类型,可W表示当前设备在进行哪一种业务类型,比如语音业务,视频业务,抄表业务等。 [0034] The service type; beacon transmission device is used to identify the required service type, this device can be performed which W represents a service type, such as voice services, video services, service meter reading and the like. 需要说明的是,设备的业务类型可W 预先定义优先级。 Note that the service type device W can be pre-defined priority.

[0035] 通信对端设备标识;用来唯一标识通信对端设备,该通信对端设备标识根据信标帖的类型,设置不同的通信对端设备的标识; [0035] The communication peer device identifier; used to uniquely identify the communication peer device, the peer device communication identifier according to the type of the beacon posts, a different set of peer communication device identification;

[0036] 所申请资源数量;表示信标帖的发送设备在下一超帖中申请的资源数量。 [0036] The amount of resources requested; represents the number of resource beacon transmitting device application posts in the next super quote. 需要说明的是,为公平起见,可W限定每个超帖周期内,每个设备申请的资源的数量,W为其它设备在同一个超帖中申请资源保留机会; It should be noted that, in fairness, W can define within each super post cycle, the amount of resources each device applications, W for other devices in the same opportunity to apply for resource reservation in a super-post;

[0037] 信息发送的位置:指示当前超帖中,信息发送所使用的资源位置。 [0037] The location information transmitted: indicates the current super-post, the location information transmission resource used.

[003引需要说明的是,上述字段,并不一定会在每个类型的信标帖中都全部包含,可W根据功能需要进行取舍。 [003 cited Incidentally, the above-mentioned fields, are not necessarily all included in each type of beacon post, according to the function W may need to compromise. 信标帖所包括的内容可W根据"信标帖类型标识"字段确定。 Beacon posts may be included in the W content is determined according to a "beacon signature type identifier" field.

[0039] 则本发明实施例在实际应用中,把可用资源定义为"超帖周期",并把一个"超帖周期"划分成"信标周期"和"数据周期",参与D2D通信的设备可W在"信标周期"内发送各种类型的信标帖,在"数据周期"内发送信息。 [0039] In the embodiment of the present invention in practical applications, the available resources is defined as "super post cycle", and to a "super post cycle" into a "beacon period" and "data period", participate D2D communication device W may send various types of beacons in post "beacon period", the information transmitted in the "data period." 其中,"超帖周期"并不局限于时域上的一段时间,也可W是一段时间和/或一段频段上的所有可用资源。 Wherein, "super post cycle" is not limited to a period of time in the time domain, it may be all available resources and W is or the period of time / period of bands. 比如,可W是LTE(LongTerm Evolution,长期演进)系统中的一个子帖中的所有可用时频资源块;同样,"信标周期"和"数据周期"也不局限于时域上的一段时间,也可W是频域上的一段频段。 For example, W can all resource blocks available are a sub-frequency signature LTE (LongTerm Evolution, LTE) system in the; same "beacon period" and "data period" is not limited to a period of time in the time domain , W may also be a section of the band in the frequency domain. "信标周期"又划分成若干"信标时隙",比如,可W是LTE系统中相对"信标周期"更小的一块时频资源。 "Beacon period" is divided into several "beacon slot", for example, W can be an LTE system is relatively "beacon period" a smaller time-frequency resource.

[0040] 参考图1,在本发明一个实施例中,实现本发明实施例所提供的设备发现方法的一种实施例,可W包括W下步骤: [0040] Referring to FIG 1, in one embodiment of the present invention, to realize an embodiment of a device discovery method according to the embodiment of the present invention is provided, it may comprise W W the steps of:
