Definitions
- the present invention relates to a technology for obtaining an identifier of a radio network controller (RNC), and particularly relates to a method and system for acquiring a radio network controller identifier (RNC ID, RNC Identity).
- RNC radio network controller
- the Universal Mobile Telecommunications System belongs to the third generation communication system.
- the network part of UMTS is called UMTS Terrestrial Radio Access Network (UTRAN), and the UTRAN structure is divided into wireless access networks.
- UE User Equipment
- the network elements of the wireless access network include a Radio Network Controller (RNC) and a Transceiver Base Station (Node B).
- RNC Radio Network Controller
- Node B Transceiver Base Station
- a Node B covers multiple cells, and each cell has a unique cell identity (Cell Identity), where Cell Identity contains the RNC ID of the RNC.
- the UTRAN URRAN (Registration Area) is a geographical area formed by one or more cells. Each URA has a unique identifier to indicate that it will be broadcast in system messages for all cells belonging to this URA.
- a URA may consist of cells controlled by one or more RNCs. When a UE in the URA paging (URA_PCH) state moves from one URA to another, it reports a change in its location. This process is called URA update.
- the RNC can determine the location of the UE by using the URA update reported by the UE, and control the UE by using the URA update confirmation message.
- the received system message includes "HS-DSCH paging system information".
- the cell carries the Cell Identity information. If the high 12 bits of the cell identity Cell Identity received in the system message and the "SRNC Identity" in the U_RNTI are inconsistent, the URA update process is started.
- the SRNC Identity indicates the service RNC identifier, which has the same meaning as the RNC ID.
- the U_RNTI indicates the temporary identifier of the radio network of the UE, and is composed of two parts, namely, the SRNC Identity and the S-RNTI, which are 32 bits in total; wherein the S-RNTI indicates the temporary identifier of the wireless network of the SRNC.
- the extended RNC ID is introduced in the current protocol, and the extended RNC ID can be expanded to up to 16 bits.
- the extended RNC ID is 16 bits, and the UE in the URA_PCH state supports the reception of the high-speed dedicated shared channel, if according to the existing protocol, the "HS-DSCH paging system information" cell in the received system message.
- the cell identity of the cell identity is only compared with the first 12 bits of the U_RNTI. Therefore, if the comparison result is that the first 12 bits are the same and the last 4 bits are different, the UE still considers that the RNC ID is consistent with its own RNTI, and the URA update process is not started. In this way, the RNC cannot control the UE, so the UE in the URA_PCH state cannot work normally.
- the ANR function (Automatic Neighbor Relation Function) is introduced in the UMTS.
- the ANR function is to receive the measurement control message sent by the network side in the dedicated connection state, and the information of the new cell is measured and reported to the network side.
- the information includes the RNC ID and the Cell Identity.
- the effect introduced by ANRF causes the UE to fail to switch effectively. For an air interface, it is very important to get the RNC ID correctly. Summary of the invention

Specifically, a corresponding indication cell may be added to the existing notification message to implement notification to the UE, or a notification message may be newly added, which is specifically used for Notify if the extended RNC ID is used.
- the method in which the RNC of the example indicates to the UE whether the extended RNC ID is used specifically includes the following steps:
- Step 101 The RNC sends an RRC message to the UE, where the RRC message includes an indication cell "extended RNC ID Ind” indicating whether the RNC ID uses 16 bits.
- the "extended RNC ID Ind” cell is used to indicate whether the extended RNC ID is used on the network side. For example, when the RNC sends the RRC message to the UE to carry the "extended RNC ID Ind” cell, it means that the RNC ID used by the network side is the extended RNC ID, that is, the RNC ID used is 16 If the RRC message is sent to the UE and does not carry the "extended RNC ID Ind” cell, it means that the RNC ID used by the network side is a normal RNC ID, that is, the used RNC ID. Is a 12-bit RNC ID.
- the RRC message sent by the RNC to the UE may be a new interface message, and the interface message is specifically used to notify the UE whether the RNC ID used by the network side is an extended RNC ID. It is also possible to indicate whether the network side uses the extended RNC ID by sending the new notification message; for example, when the UE receives the new message, confirm that the network side uses the extended RNC ID, and when the new RNC ID is not received, When adding a message, confirm that the network side uses the normal RNC ID.
- the name of the above new message can be called RNC ID Notify Information, or another name.
- the existing message can also be used as the notification message of whether the network side uses the extended RNC ID, such as using the system message SIB3, that is, expanding the existing SIB3, and inserting the aforementioned "extended RNC ID Ind" in the SIB3.
- Step 102 The UE receives the message sent by the RNC, and determines, according to the received message, whether the extended RNC ID is used by the network side.
- step 101 when the network side uses the dedicated notification message to notify the UE whether the extended RNC ID is used, when the newly added dedicated notification message, such as RNC ID Notify Information, is received, the current RNC ID is indicated. If the extended RNC ID is not received, such as the RNC ID Notify Information, the current RNC ID is the normal RNC ID.
- the newly added dedicated notification message such as RNC ID Notify Information
- the newly added notification message or the existing message may include whether the network side is an indication cell that uses the extended RNC ID, such as "extended RNC ID Ind"
- the message includes the extended RNC ID Ind
- the UE It is considered that the RNC uses a 16-bit RNC ID and decodes it according to the 16-bit RNC ID. If the message does not contain the extended RNC ID Ind, the UE considers that the RNC uses the 12-bit RNC ID and decodes according to the 12-bit RNC ID.
- the UE in the URA_PCH state if receiving the reception of the high-speed dedicated shared channel, includes the "HS-DSCH paging system information" cell in the received system message.
- the upper 16 bits of the cell identity Cell Identity are parsed in the "HS-DSCH paging system information” cell, and the "SRNC identity" in the U_RNTI in the SIB5 is compared with the first 4 bits of the S-RNTI. If not, the UR A is started. Update process; Of course, if they are consistent, there is no need to start the UR A update process.
- FIG. 2 is a flowchart of an RNC indicating an RNC ID to a UE according to Embodiment 2 of the present invention.
- the RNC in the present invention indicates to the UE whether an extended RNC ID is used.
- the RNC notifies the UE whether to use.
- the specific notification mode of the extended RNC ID is an explicit notification mode. Specifically, a corresponding cell may be added to the existing notification message to carry the RNC ID, or a new notification message may be added to carry the RNC ID.
- the method in which the RNC of this example indicates to the UE whether the extended RNC ID is used specifically includes the following steps:
- Step 201 The RNC sends an RRC notification message to the UE, where the RRC notification message includes an RNC ID cell for carrying the RNC ID.
- the RNC ID used by the network side is directly notified to the UE. If the value of the RNC ID is greater than 4095, the RNC ID is a 16-bit extended RNC ID. If it is not greater than 4095, the RNC ID is a 12-bit RNC ID. That is to say, the network side directly notifies the UE of the RNC ID through the notification message. If the RNC ID in the notification message is greater than 12 digits, the RNC ID is the extended RNC ID, otherwise it is the normal RNC ID (12 digits).
- the message sent by the RNC to the UE may be a new interface message, such as the name of the RNC ID Notify Information, or other message name; or the notification message is an existing system message.
- Step 202 The UE receives the notification message sent by the RNC. If the message contains an RNC ID, If the RNC ID is greater than 4095 (that is, greater than 12 bits), the UE considers that the RNC uses the 16-bit RNC ID. If the RNC ID in the message ranges from 0 to 4095, the UE considers that the RNC uses the 12-bit RNC ID.
- the same manner as in Embodiment 1 is used to determine whether the RNC ID is consistent with the RNC ID included in the UE's own RNTI.

- the specific notification mode of the extended RNC ID is an implicit notification mode. Specifically, whether the current RNC ID is an extended RNC ID is determined by whether the set bit in the RNC ID is a set value.
- whether the first 12 bits of the extended RNC ID are set values indicates whether it is an extended RNC ID, that is, the current 12-bit bit is a specific value such as 4095 (the first 12 bits are all "1") or 0 (previous The 12 bits are all "0"), which means that the current RNC ID is the extended RNC ID.
- the specific value mentioned above may also be other values, but only the network side and the UE side agree in advance, and the specific value is no longer used as a normal RNC ID.
- the method in which the RNC of this example indicates to the UE whether the extended RNC ID is used specifically includes the following steps:
- Step 301 The RNC sends an RRC message to the UE, where the RRC message includes the Cell Identity.
- the RNC ID is 16 bits
- the corresponding value of the first 12 bits of the Cell Identity is a special value such as 4095
- the RNC ID is the first 16 bits of the Cell Identity.
- the first 12 bits of Cell Identity are non-specific, it means that the current RNC ID is a normal RNC ID, and the first 12 bits of Cell Identity is the RNC ID.
- Step 302 The UE receives the message sent by the RNC. If the corresponding value of the first 12 bits of Cell Identity in the message is a special value such as 4095, the UE can recognize that the RNC ID uses 16 bits and solve the RNC ID according to 16 bits.
- step 401 according to the method in Embodiment 1 or Embodiment 2 or Embodiment 3, the UE may know that the network side is I used a 12bit or 16bit RNC ID.
- the UE in the URA_PCH state if receiving the reception of the High Speed Dedicated Shared Channel (HS-DSCH), acquires a system message in the received channel, and judges when the system message includes the "HS-DSCH paging system information" cell, "HS-DSCH paging system information"
- the Cell Identity high or high 16 bits in the cell are compared with the first 12 bits or the first 16 bits of the UE's own RNTI. If they match, the URA update is not initiated. Otherwise, the URA is initiated. Update.
- the 16-bit RNC ID is used on the network side, the upper 16 bits of the Cell Identity received by the SIB3 in the system message are compared with the "SRNC identity" in the U_RNTI in the SIB5, together with the first 4 bits of the S-RNTI. Inconsistent, the URA update process is initiated, otherwise the URA update process is not initiated. If the network side uses the 12-bit RNC ID, the first 12 bits of the Cell Identity received in the system message are compared with the "SRNC identity" in the U_RNTI. If they are inconsistent, the URA update process is started. Otherwise, the URA update process is not started. URA update process.
- the UE When the URA update procedure needs to be initiated, the UE sends a URA Update message (UR A UPDATE ) to the RNC.

Description
获取无线网络控制器标识的方法及系统 技术领域
本发明涉及空口获取无线网络控制器( RNC, Radio Network Controller ) 标识的技术, 尤其涉及一种获取无线网络控制器标识 (RNC ID , RNC Identity ) 的方法及系统。 背景技术
通用移动电信系统 ( UMTS , Universal Mobile Telecommunications System )属于第三代通信系统, UMTS的网络部分称作 UMTS陆地无线电 接入网 ( UTRAN, UMTS Terrestrial Radio Access Network ), UTRAN结构 分为无线接入网络 ( RAN, Radio Access Network )和核心网 (CN, Core Network ), 其中无线接入网络用于处理所有与无线接入相关的业务, 而 CN 处理系统内所有的话音呼叫和数据连接与外部网络的交换和路由。 上述两 个单元与用户设备( UE, User Equipment )一起构成了整个系统。 无线接入 网络的网络单元包括无线网络控制器( RNC , Radio Network Controller )和 收发基站 ( Node B )。 一个 Node B覆盖多个小区, 每个小区都有唯一的一 个小区标识( Cell Identity ), 其中 Cell Identity包含 RNC的标识 RNC ID。
UTRAN 注册区( URA, UTRAN Registration Area )为一个或多个小区 构成的地理区域。 每个 URA都有一个唯一的标识来表示, 在属于本 URA 的所有小区的系统消息中都会广播。 一个 URA可以由一个或多个 RNC控 制的小区组成。 处于 URA寻呼( URA_PCH )状态下的 UE从一个 URA移 动到另一个 URA时,会报告其位置的改变。该过程被称作 URA更新。 RNC 通过 UE上报的 URA更新可以确定 UE所在的位置,通过 URA更新确认消 息来对 UE进行控制。
相关协议中规定, 处于 URA_PCH状态的 UE, 如果支持高速专用共享 信道(HS-DSCH, High-Speed Downlink Shared Channel ) 的接收, 在所接 收到的系统消息中包含了 "HS-DSCH paging system information" 信元, 该 信元中承载有 Cell Identity信息, 如果在系统消息中接收到的小区标识 Cell Identity的高 12bit和 U_RNTI中的 "SRNC Identity" 不一致, 则启动 URA 更新过程。其中, SRNC Identity表示服务 RNC标识,含义与 RNC ID相同。 U_RNTI表示 UE的无线网络临时标识,由两部分组成,分别是 SRNC Identity 和 S-RNTI, 共 32bit; 其中, S-RNTI表示 SRNC的无线网络临时标识。
目前协议中引入了扩展的 RNC ID, 扩展的 RNC ID最多可以扩展为 16bit。 艮设扩展的 RNC ID为 16bit, 而处于 URA_PCH状态的 UE, 如果支 持高速专用共享信道的接收, 如果按照现有的协议, 在接收到的系统消息 中的 "HS-DSCH paging system information"信元中的小区标识 Cell Identity 仅与 U_RNTI的前 12bit高位进行比较, 这样, 如果比较结果是前 12bit相 同而后 4bit不同, UE仍然会认为 RNC ID与自身的 RNTI—致, 则不会启 动 URA更新过程。这样, RNC就无法对 UE进行控制,因此处于 URA_PCH 状态下的 UE就无法正常工作。
同时, 在 UMTS 中引入了 ANR 功能 (Automatic Neighbor Relation Function ), ANR功能就是通过 UE在专用连接态下接收到网络侧下发的测 量控制消息,辅助测量新小区的信息并上报给网络侧,上报的消息包括 RNC ID和 Cell Identity等, 网络侧获取后可以得知哪些邻接 RNC的小区进行了 漏配, 可自动添加漏配的邻区配置, 同时也可以进行切换。 如果 UE读取目 标小区的系统消息中的 RNC ID和 Cell Identity后解码错误, 那么上报给 RNC后, RNC也无法正确解出, 那么会导致添加的漏配的邻区也不正确, 从而影响了 ANRF引入的效果, 导致 UE不能有效地进行切换。 对于空口 而言, 正确地获取 RNC ID是非常重要的。
发明内容
有鉴于此, 本发明的主要目的在于提供一种获取无线网络控制器标识 的方法及系统, 在网络侧使用扩展的 RNC ID时能及时通知 UE, UE能准 确判断所接收到的扩展的 RNC ID是否正确,从而能准确判断是否进行 URA 更新。
为达到上述目的, 本发明的技术方案是这样实现的:
一种获取无线网络控制器标识的方法, 包括:
网络侧将使用扩展的 RNC ID的信息通知 UE;
所述 UE从所接收的网络侧的系统消息中获取扩展的 RNC ID。
优选地, 所述方法还包括:
所述 UE确定所获取的扩展的 RNC ID与自身的 RNTI中包含的 RNC ID 是否一致, 不一致时发起 URA的更新。
优选地, 所述 UE确定所获取的扩展的 RNC ID与自身的 RNTI中包含 的 RNC ID是否一致具体为:

本发明的基本思想为, 当网络侧确定使用扩展的 RNC ID时,将会通知 给 UE, 这样, UE即可对所接收到的小区 ID进行相应的判断, 当确定所接 收到的 RNC ID与自身的 RNTI中包含的 RNC ID不一致时, 将发起 URA 的更新。
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
实施例 1
图 1为本发明实施例 1的 RNC向 UE指示 RNC ID的流程图, 如图 1 所示, 本发明中的 RNC向 UE指示是否使用了扩展的 RNC ID, 本示例中, RNC通知 UE是否使用了扩展的 RNC ID的具体通知方式为显式通知方式; 具体的, 可以在现有通知消息中增加相应的指示信元来实现对 UE的通知, 或者, 新增设一条通知消息, 专门用于通知是否使用了扩展的 RNC ID。 本 示例的 RNC向 UE指示是否使用了扩展的 RNC ID的方法具体包括以下步 骤:
步骤 101 , RNC向 UE发送 RRC消息,该 RRC消息中包括了一个指示 RNC ID是否釆用 16bit的指示信元 "extended RNC ID Ind"。 该 "extended RNC ID Ind" 信元用于指示网络侧是否是使用了扩展的 RNC ID。 例如, 当 RNC向 UE发送 RRC消息中携带该 "extended RNC ID Ind" 信元时, 即意 味着网络侧所使用的 RNC ID为扩展的 RNC ID, 即所使用的 RNC ID为 16
位的 RNC ID; 而如果 RRC向 UE发送 RRC消息中不携带有该 "extended RNC ID Ind"信元时,则意味着网络侧所使用的 RNC ID为普通的 RNC ID, 即所使用的 RNC ID为 12位的 RNC ID。
RNC向 UE发送的 RRC消息, 可以为一条新增的接口消息, 该接口消 息是专门用于通知 UE网络侧所使用的 RNC ID是否是扩展的 RNC ID。 也 可以通过是否发送该新增的通知消息来指示网络侧是否使用扩展的 RNC ID; 例如, 当 UE接收到该新增消息时, 确认网络侧使用扩展的 RNC ID, 而当未接收到该新增消息时, 确认网络侧使用普通的 RNC ID。 上述的新增 消息的名称可称为 RNC ID Notify Information , 或者其它名称。
当然,也可以使用现有的消息作为网络侧是否使用扩展的 RNC ID的通 知消息, 如釆用系统消息 SIB3 , 即对现有的 SIB3进行扩展, 在 SIB3中插 入前述的 "extended RNC ID Ind"信元, 用于指示网络侧是否使用了扩展的 RNC ID。
步骤 102, UE接收到 RNC发送的消息,并根据所接收消息确定网络侧 是否使用了扩展的 RNC ID。
针对步骤 101中的情形,当网络侧釆用专用通知消息通知 UE是否釆用 了扩展的 RNC ID时, 当接收到新增设的专用通知消息如 RNC ID Notify Information时, 则说明当前的 RNC ID为扩展的 RNC ID, 而未接收到新增 设的专用通知消息如 RNC ID Notify Information时, 则说明当前的 RNC ID 为普通的 RNC ID。
当然, 也可以不论新增通知消息或现有消息, 均可以包含网络侧是否 是使用了扩展的 RNC ID的指示信元如 "extended RNC ID Ind" , 如果消息 中包含了 extended RNC ID Ind, UE认为 RNC釆用了 16bit的 RNC ID, 按 照 16bit的 RNC ID进行解码。 如果消息中没有包含 extended RNC ID Ind, UE认为 RNC釆用了 12bit的 RNC ID, 按照 12bit的 RNC ID来解码。
具体的, 如果网络侧釆用了扩展的 RNC ID, 则处于 URA_PCH状态的 UE, 如果支持高速专用共享信道的接收, 在所接收的系统消息中包含了 "HS-DSCH paging system information" 信元, 在 "HS-DSCH paging system information" 信元中解析出小区标识 Cell Identity的高 16bit, 与 SIB5中的 U_RNTI中的 "SRNC identity" 连同 S-RNTI的前 4bit进行比较, 如果不一 致, 则启动 UR A更新过程; 当然, 如果一致, 则不需要启动 UR A更新过 程。
实施例 2
图 2为本发明实施例 2的 RNC向 UE指示 RNC ID的流程图, 如图 2 所示, 本发明中的 RNC向 UE指示是否使用了扩展的 RNC ID, 本示例中, RNC通知 UE是否使用了扩展的 RNC ID的具体通知方式为显式通知方式; 具体的, 可以在现有通知消息中增加相应的信元来承载 RNC ID, 或者, 新 增设一条通知消息来承载 RNC ID。 本示例的 RNC向 UE指示是否使用了 扩展的 RNC ID的方法具体包括以下步骤:
步骤 201 , RNC向 UE发送 RRC通知消息 ,该 RRC通知消息中包括了 一个用于承载 RNC ID的 RNC ID信元。
本示例中, 直接将网络侧所使用的 RNC ID通知给 UE; 如果 RNC ID 的值大于 4095 , 则 RNC ID为 16bit的扩展 RNC ID, 如果不大于 4095 , 则 RNC ID为 12bit的 RNC ID。也就是说,网络侧直接通过通知消息将 RNC ID 通知给 UE。如果通知消息中的 RNC ID大于 12位, 则说明该 RNC ID为扩 展的 RNC ID, 否则即是普通的 RNC ID ( 12位)。
RNC向 UE发送的消息, 可以为一条新增的接口消息, 如名称为 RNC ID Notify Information, 或者其它的消息名称; 或者, 通知消息为现有的系 统消息。
步骤 202, UE接收到 RNC发送的通知消息。如果消息中包含了 RNC ID,
且 RNC ID大于 4095(即大于 12位),则 UE认为 RNC釆用了 16bit的 RNC ID。如果消息中的 RNC ID的范围在 0到 4095之间, 则 UE认为 RNC釆用 了 12bit的 RNC ID。
当确定出 RNC ID是否是扩展的 RNC ID后,釆用如实施例 1相同的方 式来判断 RNC ID与 UE自身的 RNTI中包含的 RNC ID是否一致。
实施例 3
图 3为本发明实施例 3的 RNC向 UE指示 RNC ID的流程图, 如图 3 所示, 本发明中的 RNC向 UE指示是否使用了扩展的 RNC ID, 本示例中, RNC通知 UE是否使用了扩展的 RNC ID的具体通知方式为隐式通知方式; 具体的,通过 RNC ID中的设定位是否为设定值来指示当前的 RNC ID是否 是扩展的 RNC ID。 本示例中, 是以扩展 RNC ID的前 12位是否是设定值 来标示是否是扩展 RNC ID, 即当前 12位比特为特定值如 4095 (前 12位全 为 "1" )或 0 (前 12位全为 "0" ), 则意味着当前的 RNC ID为扩展的 RNC ID。 当然, 上述的特定值也可以是其他值, 只是, 网络侧与 UE侧事先约定 即可, 该特定值不再用于作为普通的 RNC ID。 本示例的 RNC向 UE指示 是否使用了扩展的 RNC ID的方法具体包括以下步骤:
步骤 301 , RNC向 UE发送 RRC消息, 该 RRC消息中包含了 Cell Identity, 如果 RNC ID为 16bit, 则 Cell Identity的前 12bit的对应的值为一 个特殊值如 4095 , RNC ID是 Cell Identity的前 16bit。当然,如果 Cell Identity 的前 12位为非特定值, 则意味着当前的 RNC ID为普通的 RNC ID, Cell Identity的前 12bit即为 RNC ID。
步骤 302, UE接收到 RNC发送的消息。 如果消息中 Cell Identity的前 12bit的对应的值为一个特殊值如 4095 , 则 UE可以识别出 RNC ID釆用了 16bit, 按照 16bit来解 RNC ID。
隐式通知方式中, 也可以是 RNC ID的前 12位为 0 ( 12位全为 "0" )
来表示扩展的 RNC ID, 或者, 扩展的 RNC ID的前 n ( n<=12 )位为其他特 定值(该特定值一旦用于指示扩展的 RNC ID, 该设定位的特定值将不再用 于普通的 RNC ID中)。
本示例中, 当确定出 RNC ID是否是扩展的 RNC ID后, 釆用如实施例 1相同的方式来判断 RNC ID与 UE自身的 RNTI中包含的 RNC ID是否一 致。
实施例 4
图 4为本发明实施例 4的 UE进行 URA更新的流程图, 如图 4所示, 步骤 401 , 根据前述实施例 1或实施例 2或实施例 3中的方法, UE可 以得知网络侧是釆用了 12bit还是 16bit的 RNC ID。
处于 URA_PCH状态的 UE, 如果支持高速专用共享信道(HS-DSCH ) 的接收, 在所接收的信道中获取系统消息, 并在系统消息中包含了 "HS-DSCH paging system information" 信元时, 判断 "HS-DSCH paging system information" 信元中的 Cell Identity高 12位或高 16位与 UE自身的 RNTI的前 12位或前 16位进行比较, 如果一致, 则不发起 URA更新, 否 则, 发起 URA更新。
网络侧如果釆用了 16bit的 RNC ID,则将系统消息中 SIB3接收到的小 区标识 Cell Identity的高 16bit,与 SIB5中的 U_RNTI中的 "SRNC identity" 连同 S-RNTI的前 4bit进行比较, 如果不一致, 则启动 URA更新过程, 否 则不启动 URA更新过程。 网络侧如果釆用了 12bit的 RNC ID,在系统消息 中接收到的小区标识 Cell Identity的前 12bit和 U_RNTI中的 "SRNC identity" 进行比较即可, 如果不一致, 则启动 URA更新过程, 否则不启动 URA更 新过程。 当需要启动 URA更新过程时, UE向 RNC发送 URA更新消息 ( UR A UPDATE )。
步骤 402, RNC向 UE发送确认消息 URA UPDATE Confirm消息, 消 息中包括新的 URNTI等信息。
网络侧将为 UE分配的 RNTI通知给 UE, 实现对 UE的 URA更新。 实施例 5
图 5为本发明实施例 5的 ANRF的流程图,如图 5所示 ,本示例的 ANRF 具体包括以下步骤:
步骤 501 , 根据实施例 1中或实施例 2或实施例 3中的方法, UE可以 得知网络侧是釆用了 12bit还是 16bit的 RNC ID。
UE在满足网络侧下发的测量上报条件时进行上报, 上报消息中包含了 RNC ID。
步骤 502, 网络侧收到 UE上报的消息后, 自动进行邻区配置更新, 同 时根据 UE上报的 RNC ID可以识别出是哪些 RNC的小区进行了漏配, 可 以和邻接的 RNC进行信息交换,以便邻接 RNC也可以把本 RNC的小区配 置为邻区。
图 6为本发明获取无线网络控制器标识的系统的组成结构示意图, 如 图 6所示, 本发明获取无线网络控制器标识的系统包括通知单元 60和获取 单元 61 , 其中,
通知单元 60, 设置于网络侧, 用于将网络侧使用扩展的 RNC ID的信 息通知 UE; 具体的, 通知单元 60可通过专用的通知消息或扩展的现有系 统消息将网络侧是否使用扩展的 RNC ID的信息通知 UE。 关于通知消息的 实现方式, 具体可参见前述实施例 1至实施例 3中的相关描述。
