Description

通信网络重选的方法 Communication network reselection method

技术领域 FIELD

[0001] 本发明涉及通信领域,特别是,涉及一种重新选择一个通信系统网络的方法。 [0001] The present invention relates to communication field, in particular, to a communication system, a network reselection method. 背景技术 Background technique

[0002] 每当手机开机或者用户移动到一个新的注册区域时,手机会发起一个公众陆地移动通信网络(以下简称PLMN)发现过程。 [0002] Every time the phone is switched or the user moves to a new registration area, the phone will initiate a Public Land Mobile Network (hereinafter PLMN) discovery process. 通常情况下,手机在其家乡PLMN(以下简称HPLMN) 的服务范围内移动,接收其HPLMN的服务。 Typically, mobile phone services within the scope of its home PLMN (hereinafter referred to as HPLMN), and receives its HPLMN services. 这个HPLMN通常就是与用户签约的服务提供商所提供的PLMN。 This is usually the HPLMN and PLMN user subscription service providers. 比如,某个手机号码为13901234567的“全球通”用户与中国移动签约之后,中国移动所提供的PLMN网络就是这个手机的HPLMN。 For example, a cell phone number is 13901234567 the "Global" after the user has signed with China Mobile, PLMN network provided by China Mobile is the mobile phone HPLMN.

[0003] 一般而言,在与服务提供商签约后,每个签约用户都会获得一个被用来唯一标识用户身份的代码——国际移动台识别码(以下简称IMSI),这个IMSI通常会保存在一个小小的SIM卡内部。 [0003] Generally, after signing the contract with the service provider, each subscriber will get a code that is used to uniquely identify the user identity - international mobile station identification number (hereinafter referred to as IMSI), typically the IMSI stored in a small internal SIM card. 这个SIM卡能够被插在手机里面,在需要时可以用来标识用户身份的代码。 The SIM card can be inserted inside the phone, when needed can be used to identify the user's identity code. 参见图1,IMSI包含了移动国家号码(以下简称MCC)、移动网号(以下简称MNC)和客户识别码字段(以下简称MSIN),分别用来表明这个用户是属于哪个国家、这个国家的哪一个移动网络以及这个移动网络中的哪一个用户。 Referring to Figure 1, IMSI comprising a mobile country code (hereinafter referred to as the MCC), mobile number (hereinafter referred to as MNC) and a customer identification field (hereinafter referred to as the MSIN), respectively, to indicate which country the user belongs to, what country a mobile network and the mobile network in which a user. 手机是通过比较一个PLMN的移动国家号码(以下简称MCC)和移动网号(以下简称MNC)字段与IMSI的MCC/MNC字段,来知道一个PLMN是不是HPLMN。 By comparing the PLMN phone is a mobile country code (hereinafter referred to as MCC) and mobile number (hereinafter referred to as MNC) field with the IMSI MCC / MNC field to know that a PLMN is not the HPLMN. 如果手机不能够同HPLMN建立连接,那么它必须寻找连接另一个不同的PLMN,也就是拜访PLMN(以下简称VPLMN)。 If the phone can not establish a connection with the HPLMN, then it must find a different connection PLMN, which is visited PLMN (hereinafter referred to VPLMN). 通常当手机漫游到其HPLMN不能够提供覆盖的区域时,这种情况就会发生。 Often when roaming can not provide its HPLMN coverage area, this situation occurs.

[0004] 当手机选到了一个合适的PLMN时,它就会寻找并选择所述PLMN的一个可以提供蜂窝服务的合适的小区。 [0004] When the phone is selected into a proper PLMN, it will find and select a suitable cell can provide cellular service in the PLMN. 随后手机会调谐到所选小区的控制信道上去,向网络注册其当前位置存在于所选小区所属的注册区域。 The phone is then tuned to the control channel of the selected cell up to the network registers its current location registration area is present in the selected cell belongs.

[0005] 以后,当需要发起通信时(如打电话),手机通过所选小区的控制信道接入网络。 [0005] Later, when it is desired to initiate a communication (e.g., phone), a mobile phone network through the access channel of the selected cell. 手机有时会周期性地继续寻找所选PLMN中的更合适的一个小区,这种情况有时会发生,比如手机移出了所选小区的服务范围,失去了所选小区的覆盖。 Sometimes the phone will periodically continue to look for the selected PLMN in a more suitable area, which sometimes happens, such as a mobile phone moves out of range of services selected cell, lost coverage selected cell.

[0006] 有的时候,一个特定区域可能有多于一个PLMN的覆盖,也就是说,存在PLMN服务区域的重叠。 [0006] Sometimes, there is a particular area may cover more than one PLMN, that is, there is an overlapping service area PLMN. 这时,手机在开始的时候就需要从这些存在的PLMN中选择某一个特定的PLMN,而不选择其他的PLMN。 At this time, the phone will need to select a particular PLMN from the PLMN these exist in the beginning, rather than select another PLMN. 另外,如在漫游的情况下,手机有可能失去所选PLMN的覆盖, 这时,手机必须选择另一个PLMN网络来提供服务。 In addition, as in the case of roaming, the phone may lose coverage selected PLMN, then, the phone must select another PLMN network to provide services.

[0007] 选择一个特定PLMN的操作可以是自动或者手动进行的。 [0007] a specific PLMN selection operation may be performed automatically or manually. 自动选择使用一个按照优先级排列的PLMN列表,手机从中依次选择存在的排在最前面PLMN。 Use automatic selection in accordance with a prioritized PLMN list, select the phone from which the presence at the top PLMN. 手动选择是向用户提供一个存在的PLMN的列表,用户必须从中选择一个PLMN。 Manual option is to provide a list of PLMN of an existing user, the user must select a PLMN. 通常情况下,用户的决定应该受到尊重,也就是说,应该允许用户接入他所手动选择的那个PLMN。 Under normal circumstances, the user's decision should be respected, that is to say, should allow the user to access the PLMN he manually selected.

[0008] 通常情况下,可用的PLMN列表和他们的优先级决定于哪个网络提供最强的信号或者说最强的射频(以下简称RF)。 [0008] Typically, PLMN list their priorities and decisions available to provide the strongest signal or the strongest radio frequency (hereinafter referred to as RF) in which network. 例如,如果第一个PLMN的提供商提供了比第二个PLMN的提供商更强的信号,那么手机在列表里面将第一个PLMN排在第二个PLMN更靠前的位置,这样,如果手机使用了自动选择,那么第一个PLMN将基于其信号强度而被自动选择。 For example, if the first PLMN provider provides a stronger signal than the second PLMN provider, then the mobile phone in the list inside the first row in the second PLMN PLMN more forward position, so that if phone uses automatic selection, then the first PLMN will be automatically selected based on their signal strength. 如果选择了一个VPLMN,那么手机可能会持续周期性的寻找其HPLMN。 If a VPLMN is selected, the phone may continue periodically to find its HPLMN. 关于目前的PLMN选择的更详细的说明,可以参阅“Universal MobileTelecommunications System(UMTS)Non-Access-Stratum functions related toMobile Station(MS)in idle mode, " 3GPP TS23. 122, v. 4. 1. O, Release4, European Telecommunications Standards Institute(2001)。 A more detailed description of the current PLMN selection, can be found in "Universal MobileTelecommunications System (UMTS) Non-Access-Stratum functions related toMobile Station (MS) in idle mode," 3GPP TS23. 122, v. 4. 1. O, release4, European Telecommunications Standards Institute (2001).

[0009] 随着人民群众生活水平的提高,以及移动通信事业的发展,用户从HPLMN漫游到外地的情况越来越多。 [0009] With the improvement of people's living standards, as well as mobile communications business, where the user roams from HPLMN to the field more and more. 其中,漫游目的区域就有可能存在有多个VPLMN的覆盖,也就是说, 有多个VPLMN都可以为用户提供服务。 Among them, roaming the region of interest is likely to exist covering multiple VPLMN, that is, there are multiple VPLMN that users can provide services. 这样,如果手机采用“自动选择”模式进行网络选择的话,那么根据信号的强弱,这些VPLMN都有可能被选中从而进行接入。 Thus, if the phone use "automatic selection" network selection mode, then according to the signal strength, which might be selected so VPLMN to access. 而从商业的角度而言,漫游用户所签约的HPLMN运营商可能希望差异性对待这些VPLMN。 And from a business point of view, the signing of a roaming user HPLMN operator may wish to treat these differences VPLMN. 比如,德国全境同时存在Vodafone、Orange和T_mobile三个网络。 For example, exist throughout Germany Vodafone, Orange and T_mobile three networks. 而中国移动和德国的Vodafone可能会签订协议,如果从中国漫游到德国的用户中有超过80%的用户选择了德国的Vodafone网络,那么Vodafone会给中国移动非常优惠的国际网间结算价格。 China Mobile Germany and Vodafone signed an agreement might be, if the roaming users from China to Germany in more than 80% of users chose the Vodafone network in Germany, then Vodafone will give China Mobile a very favorable international interconnection prices. 因此,在这种情况下,作为HPLMN 的中国移动可以通过现有的合适的方法,给漫游到德国的手机发送指令,让其重新选择网络接入到Vodafone网络。 Thus, in this case, China Mobile as the HPLMN by a conventional suitable method, to the roaming mobile phone to send commands to Germany, allowed access to the network reselection Vodafone network. 所述的现有的方法包括但是不限于手机和网络双方约定的特定消息、短消息。 Existing methods include, but are not limited to the specific message and mobile phone network mutually agreed upon, the short message.

[0010] 在现有系统中,HPLMN没有办法知道手机进行网络选择采用的是“自动选择”模式还是“手动选择”模式,因此,即使用户采用“手动选择”模式选择了一个VPLMN,那么HPLMN 也可能会给这个手机发送指令,让其重新选择另一个VPLMN。 [0010] In the existing system, there is no way to know the phone HPLMN network selection used the "automatic selection" mode or "manual selection" mode, so even if the user uses "manual selection" mode to select a VPLMN, HPLMN then also this may give the phone to send command, allowed to re-select another VPLMN. 这样就违背了用户的最终意愿,给用户带来不好的体验。 This contrary to the wishes of end-users, giving users a bad experience.

[0011] 另一方面,如果采用了“手动选择”模式的手机决定不接受HPLMN发来的所述的重新选择另一个VPLMN的指令,那么所述的这个指令的从HPLMN到手机的传输过程就是不必要的,这个传输过程会造成网络资源的浪费。 [0011] On the other hand, if the mobile phone "manual selection" mode is decided not to accept the HPLMN sent to another VPLMN reselection instruction, then the transmission process according to the instruction from the mobile phone is the HPLMN unnecessary, the transmission process will result in waste of network resources.

发明内容 SUMMARY

[0012] 因此,本发明的目的是提供一种手机重新选择PLMN的方法,使得手机能够根据其采用的网络选择模式,来决定是否继续进行PLMN重新选择。 [0012] Accordingly, an object of the present invention is to provide a method for PLMN reselection the mobile phone, so that the mobile phone network mode can be selected according to its use, to decide whether to proceed PLMN reselection.

[0013] 为实现上述目的,一种通信网络的重新选择方法,包括步骤: [0013] To achieve the above object reselection method, a communication network, comprising the steps of:
