Description

异系统切换或重选技术领域本发明涉及无线通信领域,特别涉及终端的切换和小区重选技术。 Inter-system handover or reselection Technical Field The present invention relates to wireless communications, and more particularly relates to a terminal handover and cell reselection techniques. 背景技术随着以通信技术和计算机技术为标志的高科技的发展,人们的生活发生了曰新月异的巨大变化,蜂窝移动通信的发展给用户带来极大的便利,目前其发展已经经历了三代。 BACKGROUND As with communications technology and computer technology as a symbol of high-tech development, people's life has undergone tremendous changes, saying crescent-specific development of cellular mobile communications giving users great convenience, currently its development has gone through three generations. 在所有的蜂窝移动通信技术中,当终端离开一个小区进入另外一个小区时,该终端所接收到的原来小区的信号必然越来越弱,而它所接收到的正在进入小区的信号也就将越来越强。 In all cellular mobile communications, when a terminal leaves a cell into another cell, the signal received by the terminal to the original cell bound to become weaker, and the signal it receives it is entering the cell stronger. 因此,终端需要切换或小区重选到新进入的小区。 Thus, the terminal needs to handover or cell reselection to a new incoming cell. 如果该终端正处于连接状态,则为了保持该终端的通信质量,必需将该终端的连接从原来的基站切换到新进入的信号较强的基站,具体地说,网络侧将该终端的邻小区列表携带在测量控制消息中下发给该终端,该终端对该列表中的各邻区发起测量,并上报测量报告,由网络侧执行切换判决,选择一个信号质量较好的小区进行切换。 If the terminal is in a connected state, in order to maintain the communication quality of the terminal, the terminal is connected to the necessary switching signal from the original base station to a stronger base station newly entering, in particular, the neighbor cell side of the network terminals list carried in the measurement control message sent to the terminal that initiates the measurement of the neighboring cell list, and to report the measurement report, the network side performs the handover decision, preferably a select switch cell signal quality. 如果该终端正处于空闲状态,则网络侧将该终端的邻小区列表携带在系统消息中下发给该终端,该终端对该列表中的各邻区发起测量,并根据测量结果重选一个信号质量较好的小区,请求接入到重选后的小区。 If the terminal is in the idle state, the neighbor cell list of the network-side terminal is carried in the message system of the terminal, the terminal initiates the measurement of the neighboring cell list, and a signal based reselection measurements better quality of the cell, after requesting access to the cell reselection. 对于只包含一个系统的网络侧,上述邻小区列表中只包含属于该系统的相邻小区,然而随着移动通信网络的发展,出现了越来越多不同的系统,如全球移动通信系统及其演进的增强数据无线接入网络(GSM EDGE RadioAccess Network,简称"GERAN")、通用移动通4言系统(Universal Mobile Telecommunications System,筒称"UMTS,,)、长期演进(Long Term Evolution, 简称"LTE")系统等,未来很可能会出现GERAN、 UMTS和LTE等多系统共存的场景,终端需要在属于不同系统的小区之间进行切换或小区重选, 此时,网络侧下发的邻小区列表中可以包含属于不同系统的相邻小区。终端在需要切换或小区重选时,同样根据邻小区列表来进行小区测量,选择一个信号质量较好的小区进行切换或小区重选,该小区可以是同系统小区,也可以是异系统小区。然而,本发明的发明人发现,由于不同系统之间的 For a system containing only the network side of the neighbor cell list contains only neighboring cells belonging to the system, but with the development of mobile communication networks, there has been a growing number of different systems, such as Global System for Mobile communication system and evolved enhanced data radio access network (GSM EDGE RadioAccess network, referred to as "GERAN"), universal mobile telecommunications system made 4 (universal mobile Telecommunications system, said cartridge "UMTS ,,), long term evolution (long Term Evolution, referred to as" LTE ") systems, is likely to occur in the future GERAN, UMTS and LTE systems coexist multiple scenes, the terminal needs to handover between cells belonging to a cell or a different system reselection case, sent by the network side, a neighbor cell list may be included in neighboring cells belonging to a different system. when the terminal needs a handover or a cell reselection, a cell is measured according to the same neighbor cell list to select a signal quality better cell handover or cell reselection, the cell may be a the same cell system, or may be inter-system cell. However, the present inventors found that, because of the different systems 载是不同的,有的系统的小区信号质量虽然较好,但负载已经较大,对于这种系统的小区是不适合继续容纳进行切换或小区重选的终端的,因为很可能由于终端的切换或小区重选,使负荷已经较大的系统超过其负载承受能力,影响该系统中原有终端的业务质量。因此,本发明的发明人认为,终端进行系统之间的小区重选和切换时需要考虑各个系统的负载情况,从而进行更合理的切换和小区重选。然而,由于切换和小区重选主要是在无线接入网(Radio Access Network, 简称"RAN")侧进行的,如在基站侧进行,现有技术中不同系统的接入网设备之间并不能进行负载信息的交互,从而无法结合负载情况进行终端的切换和小区重选。发明内容本发明实施方式要解决的主要技术问题是提供一种异系统切换或重选, 使得不同系统间负载更为均衡。为解决上述技术问题 The carrier is different, some cell systems, although the signal quality is better, but has a large load for a cell of this system is not suitable to continue receiving a cell reselection or handover of the terminal, because it is likely due to the switching terminal or cell reselection, the load of the system has been greater than its load bearing capacity, affect the quality of the service system of the original terminal. Thus, the present inventors believe that the terminal needs to perform a cell reselection and handover between systems consider the case of each system load, so that a more rational handover and cell reselection. However, since the handover and cell reselection is mainly performed in a radio access network (radio Access network, abbreviated "RAN") side, as in the base station the side to the load and can not interact prior art information between different access network device of the system, and thus can not load in conjunction with switching and terminal cell reselection. SUMMARY oF tHE iNVENTION the main technical problem to be solved by the embodiment to provide an inter-system handover or reselection, so that more balanced load between different systems. In order to solve the above problems ,本发明的实施方式提供了一种异系统切换或重选方法,包含以下步骤:第一系统的无线接入网节点获取与该节点下属小区相邻的第二系统中的小区的负载信息;第一系统的无线接入网节点根据所获取的负载信息协助该节点下属小区内的终端进行涉及第二系统中小区的切换或重选。本发明的实施方式还提供了一种无线接入网节点,该无线接入网节点属于第一系统,第一系统的无线接入网节点包含:信息获取单元,用于获取与本节点下属小区相邻的第二系统中小区的负载信息;切换或重选单元,用于根据所获取的负载信息协助本节点下属小区内的终端,进行涉及第二系统中小区的切换或重选。 , Embodiments of the present invention there is provided an inter-system handover or reselection method, comprising the steps of: a first radio access network node acquires system information of the second system under the load cell to the node adjacent to the cell;

RAN2收到该指示消息后,从该指示消息中获取CELL1的负载信息和其它需要的信息,保存所获取的CELL1 的负载信息。 RAN2 After receiving the indication message, acquires from the load indication message information and other information needed CELL1, preservation of the acquired load information of CELL1. 在步骤140中,RAN2以广播的形式在CELL2中下发该CELL1的负载信息和其它需要的信息,指示CELL2内空闲态的终端根据该负载信息进行'J 、 区重选,即,如果该负载信息显示CELL1中负载过高(大于第一门限)则终端不再小区重选到CELL1,如果该负载信息显示CELL1中负载小于第二门限,则在需要时终端可以重选到CELL1。 In step 140, RAN2 form of broadcast load information and other information required for the CELL1 is issued in CELL2, the indication idle state of the terminal of the load information according to the 'J, reselection within CELL2, i.e., if the load CELL1 information display load is too high (greater than a first threshold) then reselection to the cell terminal is no longer CELL1, the load if the load is smaller than in the information display CELL1 second threshold, when the terminal needs to reselect CELL1. 通过在小区重选时考虑负载信息, 可以有效防止两个系统之间负载的不平衡,避免过多的终端小区重选到CELL1使得系统1中的终端的服务质量降低,而系统2中的负载资源白白浪费。 By considering the load information during the cell reselection, can effectively prevent the unbalanced load between the two systems, to avoid excessive cell reselection to a terminal so that the service quality CELL1 system terminal 1 is lowered, and the load system 2 resources wasted. 在步骤150中,RAN2在CELL2内的终端上报测量报告时,根据所保存的CELL1负载信息进行切换判决,如果该负载信息显示CELL1的负载大于第一门限,则判定该终端不能够切换到CELL1,如果该负载信息显示CELL1 的负载小于第二门限,则判定该终端能够切换到CELL1,通知该终端进行切换。 In step 150, RAN2 terminals within CELL2 the measurement report, in accordance with the stored CELL1 load information for a handover decision, if the load information display CELL1 of the load is greater than a first threshold, it is determined that the terminal can not switch to CELL1, If the load information is displayed CELL1 load is smaller than a second threshold, it is determined that the terminal can be switched to CELL1, informs the terminal switch. 在步骤160中,RAN2向CN2返回负载信息响应消息Target cell info Resp,通知CN2已收到该负载信息。 In step 160, RAN2 load information returned in response to the message CN2 Target cell info Resp, CN2 notification has been received the load information. 接着进入步骤170, CN2向CN1返回负载信息响应消息。 Proceeds to step 170, CN2 load information returned in response message to CN1. 接着进入步骤180,由CN1向RAN1返回负载信息响应消息,告知RAN1 此时RAN2已收到该负载信息。 Proceeds to step 180, load information from the returned response message to CN1 to RAN1, RAN2 informing RAN1 case the load information has been received. 其中步骤140、 150和160之间没有固定的先后关系,步骤160、 170和180可以作为可选步骤,在网络传输资源较紧张时,可以不返回响应消息。 Wherein the step of 140, 150 and 160 do not have a fixed relationship, steps 160, 170 and 180 can be used as an optional step, when the network transmission resources more intense, may not return a response message. 在本实施方式中所说的负载信息可以包括:衡量小区负载的参数的值、 和/或参数值对应的负载等级。 Referred to in the present embodiment, the load information may include: a load cell to measure the value of the parameter, and / or parameter values ​​corresponding to the load level. 如可以将小区负载情况划分为1至10的负载等级,该第一门限为等级8,第二门限为等级6,也就是说等级8以上认为过载,不允许其它系统的终端接入,等级6以下认为正常,允许其它系统的终端接入。 The load cell load level may be divided into 1 to 10, the first threshold is a level 8, a second threshold level is 6, that is to say that the overload level of 8 or more, the terminal is not allowed access to other systems, level 6 considered normal or less, the terminal is allowed access to other systems. 另夕卜,在不同系统中,衡量小区负载的参数也可以不同,如在GERAN 系统中,衡量小区负载的参数包含基站发射功率、用户数目等;在UMTS系统中,衡量小区负载的参数包含:终端平均发射功率、用户数目等;在LTE 系统中,衡量小区负载的参数包含:平均吞吐量、用户数目等。 Another Xi Bu, in different systems, measure the parameters of the cell load may be different, as in the GERAN system to measure parameters of the cell load includes a base station transmit power, number of users; in a UMTS system, to measure the parameters of the cell a load comprising: average terminal transmit power, number of users; in the LTE system, to measure the load cell parameters comprising: average throughput, number of users. 应用十分灵活,可满足不同系统的需求。 The application is very flexible and can meet the needs of different systems. 另外,在本实施方式中,RAN2也可以通过相同的设置和方式向RAN1 发送CELL2的负载信息,控制CELL1内终端的切换和小区重选,从而使得不同系统的负载能够得以平衡并充分利用。 Further, in the present embodiment, RAN2 may be transmitted in the same manner and provided to the load information RAN1 CELL2 control handover and cell reselection within CELL1 terminal, so that the system can be loaded with different balance and leverage. 本发明第二实施方式同样涉及一种异系统切换或重选方法,与第一实施方式大致相同,其区别在于,在第一实施方式中,RAN1在CELL1的负载大于第一门限或小于第二门限时,向RAN2发送指示消息,通知RAN2该CELL1 的负载信息;而在本实施方式中,预先在RAN1中设置周期性定时器,在周期性定时器超时时,该RAN1向RAN2发送指示消息,通知该RAN2该CELL1 的负载信息,如图2所示,从而使得该RAN2总能实时地获取CELL1的负载信息,方便CELL2内终端的切换和小区重选。 The second embodiment of the present invention also relates to a method for inter-system handover or reselection, substantially the same manner as in the first embodiment, except that, in the first embodiment, in the RANl CELL1 load greater than a first threshold or less than a second threshold, sends the indication message RAN2, RAN2 the load information notification CELL1;

RAN2获取CELL1负载信息和其它需要的信息后,根据这些信息为终端进行切换判决,如果CELL1的负载信息显示CELL1当前负载较小,则判定该终端可以切换到CELL1,并通知该终端进行相应的切换。 After RAN2 CELL1 obtain load information and other information needed to make a handover decision based on the information terminal, the information display if the load is small CELL1 CELL1 current load, it is determined that the terminal may switch to CELL1, and notifies the terminal corresponding switching . 另外,RAN2同样可以将CELL1的负载信息和其它需要的信息以广播的形式下发给CELL2 中的终端,使得空闲态的终端能够根据这些信息进行小区重选。 Further, the same may be CELL1 RAN2 load information and other information required in the form of a broadcast to the terminal under the CELL2, so that the terminal can perform an idle state according to a cell reselection information. 通过在切换和小区重选时考虑负载信息,可以有效防止两个系统之间负载的不平衡,避免过多的终端切换或小区重选到CELL1使得系统1中的终端的服务质量降低,而系统2中的负载资源白白浪费。 Consider through handover and cell reselection the load information, the load can effectively prevent the imbalance between the two systems, to avoid excessive cell reselection or switching the terminal to the service quality that CELL1 system terminal 1 is lowered, and the system 2 load resources wasted. 同样,在本实施方式中,RAN1也可以通过相同的设置和方式从RAN2 获取CELL2的负载信息,控制CELL1内终端的切换和小区重选,从而使得不同系统的负载能够得以平衡并充分利用。 Also, in the present embodiment, RANl can be obtained by setting the same manner and from the load information RAN2 CELL2 control handover and cell reselection within CELL1 terminal, so that the system can be loaded with different balance and leverage. 本发明第五实施方式同样涉及一种异系统切换或重选方法,本实施方式与前几个实施方式不同,在前几个实施方式中,CELL1的负载信息由RAN1 直接提供,RAN1通过其连接的CN1与相邻的系统2的CN2进行信息交互, 通过CN2将CELL1的负载信息传输给RAN2;而在本实施方式中,CELL1 的负载信息由RAN1连接的网元管理系统(Element Management System,简称"EMS" ) 1提供,EMS1通过与系统2的EMS2进行信息交互,将CELLl 的负载信息传输给RAN2。 The fifth embodiment of the present invention also relates to an inter-system handover or reselection method, the present embodiment is different from previous embodiments, the front several embodiments, CELL1 load information directly from RAN1, RAN1 is connected via its the CN1 CN2 with adjacent information exchange system 2, the load information transmitted by CN2 CELL1 to RAN2; in the present embodiment, the load information CELL1 element management system connected by a RAN1 (element management system, abbreviated "EMS") 1 provides, EMS1 EMS2 through interaction with information system 2, the load information transmitted CELLl to RAN2. 具体地说,在本实施方式中,系统1的RANI内有CELL1,系统2的RAN2内有CELL2, RAN 1由网络管理节点EMS 1管理,RAN2由网络管理节点EMS2管理,EMS 1与EMS2之间可以交互信息。 Specifically, in the present embodiment, the system of inner RANI CELL1, CELL2 there RAN2 within system 2, the RAN 1 1 by a network management node managing the EMS, EMS2 RAN2 managed by a network management node, between the EMS and EMS2 1 you can exchange information. 由于不同系统的RAN之间没有直接的通信接口,但RAN与同系统的EMS之间可以交互信息,且EMS中保存有所管理的小区的负载信息,所以RAN2可以通过两个系统的EMS之间的接口,从系统1的EMS 1获取CELL 1 的负载信息。 Since there is no direct communication interface between the RAN of different systems, but can exchange information, and cell load information stored in EMS management somewhat between the EMS and the RAN with the system, so RAN2 by EMS between two systems interface, the CELL 1 1 acquires load information from an EMS system. EMS1中有关CELL1的负载信息可以是由RANI定时上才艮,或EMS1主动向RANI请求。 EMS1 CELL1 load information may be made only on the RANI Burgundy timing or EMS1 actively requests to RANI. 在本实施方式中,EMS1在CELL1的负载大于第一门限或小于第二门限时,主动发送CELL1的负载信息给相邻小区CELL2的EMS2,通过EMS2 将CELL1的负载信息发送给CELL2所属的RAN2。 In the present embodiment, in EMS1 CELL1 load greater than a first threshold or less than a second threshold, sends load information to the cell CELL1 EMS2 CELL2 of an adjacent, CELL1 sends load information belongs to RAN2 CELL2 by EMS2. 其中,具体的第一第二门限的值可以由运营商根据需要灵活制定。 Among them, the first and second specific threshold value can be set by the operator the flexibility needed. 具体如图5所示,在步骤510中,EMS1监测到CELL1的负载大于第一门限或者小于第二门限,EMS1向CELL2所属的EMS2发送负载信息指示消息Target cell info Indication,在该消息中包含CELL1的负载信息以及其他需要的信息。 5 Specifically, in step 510, EMS1 CELL1 detected load is greater than a first threshold or less than a second threshold, EMS2 EMS1 belongs to CELL2 transmits load information indicating the message Target cell info Indication, contained in the message CELL1 the load information and other information needed. 接着进入步骤520, EMS2向CELL2所属的RAN2发送该负载信息指示消息,该消息中包含CELL1的负载信息以及其他需要的信息。 Proceeds to step 520, RAN2 EMS2 CELL2 belongs to transmit the load information indication message, the message comprising CELL1 load information and other required information. RAN2收到该指示消息后,从该指示消息中获取CELL 1的负载信息和其它需要的信息并进行保存。 After receiving the indication message RAN2, CELL 1 acquires load information and other necessary information from the indication message and save it. 在步骤530中,RAN2以广播的形式在CELL2中下发该CELL1的负载信息和其它需要的信息,指示CELL2内空闲态的终端根据该负载信息进行小区重选,即,如果该负载信息显示CELL1中负载过高(大于第一门限)则终端不再小区重选到CELL1,如果该负载信息显示CELL1中负载小于第二门限,则在需要时终端可以重选到CELL1。 In step 530, RAN2 form of broadcast load information and other information required for the CELL1 is issued in CELL2, the indication idle state terminals in CELL2 be a cell based on the load information reselection, i.e., if the load information display CELL1 load is too high (greater than a first threshold) then reselection to the cell terminal is no longer CELL1, the load if the load is smaller than in the information display CELL1 second threshold, when the terminal needs to reselect CELL1. 通过在小区重选时考虑负载信息,可以有效防止两个系统之间负载的不平tf,避免过多的终端小区重选到CELL1使得系统1中的终端的服务质量降低,而系统2中的负载资源白白浪费。 By considering the load information during the cell reselection, can effectively prevent uneven load tf between two systems to avoid excessive cell reselection to a terminal so that the service quality CELL1 system terminal 1 is lowered, and the load system 2 resources wasted. 在步骤540中,RAN2在CELL2内终端上报测量报告时,根据所保存的CELL1的负载信息进行切换判决,如果该负载信息显示CELL1的负载大于第一门限,则判定该终端不能够切换到CELL1,如果该负载信息显示CELL1 的负载小于第二门限,则判定该终端能够切换到CELL1,通知该终端进行切换。 In step 540, RAN2 measurement report in CELL2 terminal, make a handover decision in accordance with the stored load information CELL1, if the load information display CELL1 of the load is greater than a first threshold, it is determined that the terminal can not switch to CELL1, If the load information is displayed CELL1 load is smaller than a second threshold, it is determined that the terminal can be switched to CELL1, informs the terminal switch. 在步骤550中,RAN2向EMS2返回负载信息响应消息Target cell info Resp,通知EMS2已收到该负载信息。 In step 550, RAN2 load information returned in response to the message EMS2 Target cell info Resp, EMS2 notification has been received the load information. 接着进入步骤560, EMS2向EMS1返回负载信息响应消息。 Then proceeds to Step 560, EMS2 information response message returned to the load EMS1. 其中步骤530、 540和550之间没有固定的先后关系,RAN2也可能先收到终端上报的测量报告,根据CELL1的负载信息进行切换判定。 Wherein the step 530, has no fixed relationship, RAN2 may receive a measurement report reported by the terminal to between 540 and 550, switching information determined according to the load of CELL1. 步骤550 和560可以作为可选步骤,在网络传输资源较紧张时,可以不返回响应消息。 Steps 550 and 560 can be used as an optional step, when the network transmission resources more intense, may not return a response message. 另外,在本实施方式中,EMS2也可以通过相同的设置和方式向RAN1 发送CELL2的负载信息,控制CELL1内终端的切换和小区重选,从而使得不同系统的负载能够得以平衡并充分利用。 Further, in the present embodiment, EMS2 may be transmitted in the same manner and provided to the load information RAN1 CELL2 control handover and cell reselection within CELL1 terminal, so that the system can be loaded with different balance and leverage. 本发明第六实施方式同样涉及一种异系统切换或重选方法,与第五实施方式大致相同,其区别在于,在第五实施方式中,EMS1在CELL1的负载大于第一门限或小于第二门限时,向RAN2发送指示消息,通知RAN2该CELL 1 的负载信息;而在本实施方式中,预先在EMS1设置周期性定时器,在周期性定时器超时时,该EMS1向RAN2发送指示消息,通知该RAN2该CELL1 的负载信息,从而使得该RAN2总能实时地获取CELL1的负载信息,方便CELL2内终端的切换和小区重选。 The sixth embodiment of the present invention also relates to a method for inter-system handover or reselection, the fifth embodiment is substantially the same manner, except that, in the fifth embodiment, in EMS1 CELL1 load greater than a first threshold or less than a second threshold, sends the indication message RAN2, the CELL load information notification RAN2 1;
