Description

能力信息获取方法、装置及系统 Capability information acquisition method, device and system

技术领域 FIELD

[0001] 本发明涉及通信领域,具体而言,涉及一种能力信息获取方法、装置及系统。 [0001] The present invention relates to communication field, particularly, to a capability information acquisition method, device and system.

背景技术 Background technique

[0002] 在相关协议中,从演进分组系统(Evolved Packet System,简称为EPS)的角度描述了演进的通用移动通讯系统陆地无线接入网(Evolved UTRAN(Universal MobileTelecommunicat1ns System Terrestrial Rad1 Access Network))内的演进的基站(NodeB) (Evolved NodeB,简称为eNodeB,eNB)的切换过程。 [0002] In a related protocol, from the evolved packet system (Evolved Packet System, referred to as EPS) describes an angle Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (Evolved UTRAN (Universal MobileTelecommunicat1ns System Terrestrial Rad1 Access Network)) within handover procedure evolved base station (NodeB) (evolved NodeB, referred to as eNodeB, eNB) of. 图1是根据相关技术的长期演进(LTE)系统内跨移动性管理实体(Mobility Management Entity,简称为MME)切换信令流程图,如图1所示,E-UTRAN内的eNB间切换过程又分为以下两类: FIG 1 is a cross according to the related art in a long term evolution (LTE) system the mobility management entity (Mobility Management Entity, referred to as MME) handover signaling flow chart, as shown, between the eNB in ​​the E-UTRAN handover procedure 1 and divided into the following two categories:

[0003] 一、基于X2接口的eNB间切换: [0003] First, based on the inter eNB X2 interface switches:

[0004] 此切换过程中MME未改变。 [0004] This handover process MME is not changed. 又可以根据服务网关(Serving Gateway,简称为S_GW)是否重定向分为X2切换(S-GW未改变)流程、X2切换S-GW重定向切换流程。 The serving gateway may turn (Serving Gateway, abbreviated as S-GW) into X2 handover whether to redirect (S-GW is not changed) process, X2 handover redirection S-GW handover procedure. 切换准备阶段源eNB决定哪些承载需要进行分组转发。 The source eNB handover preparation phase determines which bearer for packet forwarding.

[0005] 二、基于SI接口的eNB间切换: [0005] Second, the interface between the eNB SI based handover:

[0006] 基于X2接口的切换不可用时,E-UTRAN可以发起基于SI的切换。 [0006] handover with the X2 interface is not based, E-UTRAN may initiate handover based SI. 此过程中MME可以重定向、S-GW也可能重定向。 This process can be redirected MME, S-GW may be redirected. 当UE已经移动离开为其服务的MME时,MME需要重定向,源MME选择目标MME,目标MME决定S-GW是否重定向。 When the UE has moved away from its services MME, MME needs to be redirected, the source MME selects target MME, S-GW target MME decides whether to redirect.

[0007] 源eNB决定哪些承载需要进行分组转发(DL FORWARDING)。 [0007] The source eNB determines which bearer packet forwarding (DL FORWARDING). 分组转发可以采用直接方式通过源eNB直接转发到目标MME,也可以间接地通过源或者目标S-GW转发。 The packet forwarding mode can be used directly by the source eNB forwards directly to the target MME, may be forwarded by the source or indirectly target S-GW. 源eNB判断X2连接可用,则采用直接方式;若不可用则采用间接转发方式。 Analyzing the source eNB X2 connection is available, the direct mode; If forwarding is available through an indirect manner.

[0008] 协议规定跨核心网(Core Network,简称为CN)节点之间是不能传递用户设备(User Equipment,简称为UE,也称终端)能力相关的信息的,所以UE在发生跨CN的切换之后,在切换目标小区所对应的MME是没有保存UE的能力信息。 [0008] The agreement across a core network (Core Network, abbreviated as CN) is not transmitted between a user equipment node (User Equipment, UE for short, also referred to as the terminal) related to the capability information, the UE handover occurs across CN Thereafter, the handover target cell in the corresponding MME is not stored UE capability information. 当UE切换到目标小区之后,可能因为用户激活定时器(User Inactive)定时器超时释放进去空闲(IDLE)态。 When the UE switches to the target cell, probably because the user activates the timer (User Inactive) released into the idle timer expires (IDLE) state. 之后如果UE要发起随机接入,此时接入的过程中,核心网由于没有该UE的能力信息,所以空口会发起UE能力查询过程获取UE能力信息。 If, after UE to initiate a random access procedure. The access, the core network information is not due to the ability of the UE, so the air interface will initiate the process of obtaining UE capability inquiry UE capability information. 这一过程会导致UE接入时延的增加。 This process will lead to increased UE access delay.

[0009] 针对相关技术中基于SI接口的跨CN的eNB间切换后的接入时延较长的问题,目前尚未提出有效的解决方案。 [0009] in the related art after a long delay between access across the CN eNB SI interface based switching problem, we have not yet come up with effective solutions.
