[0048] 步骤205、 RNC发起建立主叫UE的Iu接口用户面承载。 [0048] Step 205, RNC initiates the establishment of Iu interface user plane bearer calling UE.

[0049] 步骤206、 RNC向CN应答RAB指配响应消息。 [0049] Step 206, RNC refers to the response RAB assignment response message to the CN.

[0050] 步骤207、 MSC寻呼被叫UE。 [0050] Step 207, MSC pages the called UE.

[0051] 步骤208、被叫UE向MSC发送寻呼响应消息。 [0051] Step 208, the called UE sends a paging response message to the MSC.

[0052] 步骤209、MSC判断主叫UE和被叫UE是否在同一个RNC下,如果是,执行步骤210,如果否,后续流程与现有技术相同,结束本流程。 [0052] Step 209, MSC determines whether the calling UE and the called UE in the RNC the same, if so, step 210 is performed, and if not, the prior art processes follow the same, the process ends.

[0053] 步骤210、MSC判断主叫UE和被叫UE的语音编码速率是否相同,如果不相同,先执行步骤211,之后执行步骤212,如果相同,直接执行步骤212。 [0053] Step 210, MSC determining speech encoding rate of the calling UE and the called UE is the same, if not identical, to step 211, after performing step 212, if the same, step 212 is directly executed.

[0054] 步骤211、将主叫UE和被叫UE的语音编码速率调整为相同,比如第一语音编码速率。 [0054] Step 211, the speech coding rate the calling UE and the called UE is adjusted to be the same, such as a first speech encoding rate.

[0055] 步骤212、 MSC向RNC发送无线接入承载RAB指配消息,该消息中携带本地交换信息,本地交换信息包括:本地交换指示(Local Switch)、主叫标识、被叫标识。 [0055] Step 212, MSC transmits to the RNC a Radio Access Bearer RAB assignment message, which carries information on the local exchange, the local exchange of information comprising: a local switching indication (Local Switch), Caller ID, called ID. 当主叫UE和被叫UE的语音编码速率不相同时,该无线接入承载RAB指配消息中还携带:调整得到的第一语音编码速率。 When the voice coding rate of the calling UE and the called UE are not the same, the radio access bearer RAB assignment message further carries: a first speech coding rate adjustment obtained.

[0058] 当步骤212中的无线接入承载RAB指配消息中携带了第一语音编码速率时,本步骤中的RNC需要根据第一语音编码速率,建立与主叫UE间的用户面承载,以及建立与被叫UE间的用户面承载。 [0058] When in step 212 a radio access bearer RAB assignment message carries a first speech coding rate, this step is required in accordance with a first RNC speech coding rate, establishing a bearer plane between the calling user and the UE, and the user plane bearer establishment between the called UE.

[0059] 如果上述步骤210中MSC判断得到主叫UE和被叫UE的语音编码速率相同时,在步骤212中的RAB指配消息中可以不用携带该相同的语音编码速率,在该步骤213中RNC 根据该相同的语音编码速率,建立与主叫UE间的用户面承载,以及建立与被叫UE间的用户面承载。 [0059] If the MSC determines in step 210 above to give the speech coding rate the calling UE and the called UE are the same, in step 212 an RAB assignment message may not carry the same voice coding rate, in step 213 RNC according to this same speech coding rate to establish the user plane bearer between the UE and the calling party, and establishing a user plane bearer between the called UE.

[0060] 步骤214、RNC配置主叫UE数据转发地址是被叫UE的地址;配置被叫UE数据转发地址是主叫UE的地址。 [0060] Step 214, RNC calling UE configuration data forwarding address is the address of the called UE; UE configuration data forwarding address is called the address of the calling UE.

[0061] 步骤215、RNC接收来自主叫UE的数据。 [0061] Step 215, RNC receives the data from the calling UE.

[0062] 步骤216、RNC根据主叫UE数据的转发地址,将来自主叫UE的数据转发到被叫UE。 [0062] Step 216, RNC according to the data forwarding address calling UE, the calling UE from the data forwarded to the called UE. [0063] 步骤217、RNC接收来自被叫UE的数据。 [0063] Step 217, RNC receives the data from the called UE.

[0065] 其中,步骤215、216,与步骤217、218为并列关系,并不限定其执行的先后顺序。 [0065] wherein, step 215,216, step 217,218 is the parallel relationship, it is not limited to the order of execution. [0066] 在步骤209或者步骤212之后,该方法还可以包括:释放为主叫UE建立的Iu 口用 [0066] After step 209 or step 212, the method may further comprise: releasing the calling UE establishes an Iu oral

户面承载。 User plane bearer.

[0067] 在上述实施例一中,主叫UE可以作为第一用户设备,被叫UE作为第二用户设备, 或者主叫UE作为第二用户设备,被叫UE作为第一用户设备,不影响本发明的实现。 [0067] In one embodiment the above-described embodiment, the calling UE as a first user equipment, called UE as the second user device, or user equipment as a second calling UE, the called user equipment UE as the first, does not affect implementation of the invention. [0068] 上述基站控制器可以采用自适应多速率编码(Adaptive Multi-RateCoding, AMRC)技术,AMRC根据网络状况,可以调整主叫UE和被叫UE的语音编码速率,将用于与第一用户设备和第二用户设备建立用户面承载的语音编码速率改成第二语音编码速率,从而以最合适的速率保证语音的通话质量达到最优。 [0068] The base station controller may employ adaptive multi-rate coding (Adaptive Multi-RateCoding, AMRC) technology, the AMRC based on network conditions, it is possible to adjust the voice coding rate of the calling UE and the called UE, for the first user device and the second user equipment to establish a voice coding rate is changed to a second user plane bearer speech encoding rate so as to ensure the optimum rate to achieve optimal voice call quality. 其中,用于与第一用户设备和第二用户设备建立用户面承载的语音编码速率可以是:上述第一用户设备和第二用户设备相同的语音编码速率,或者上述调整得到的第一语音编码速率。 Wherein the speech coding rate for establishing the user plane bearer with the first user and the second user equipment device may be: a first speech encoding the same first user equipment and second user equipment speech coding rate, or the adjustment obtained rate. 基站控制器再根据第二语音编码速率, 建立与第一用户设备之间的用户面承载,建立与第二用户设备之间的用户面承载。 According to a second base station controller further speech coding rate, is established between the first user device and the user plane bearer, and establishing a user plane bearer between the second user equipment. 举例说明:假定MSC调整主叫UE和被叫UE的第一语音编码速率为64kbps,当网络中接入更多的用户设备时,基站控制器根据网络实际情况,利用AMRC技术将64kbps的语音编码速率降低到12. 2kbps (可以作为第二语音编码速率),以最合适的速率保证语音的通话质量达到最优。 Example: assume that the calling UE and the called MSC to adjust the UE a first speech encoding rate of 64kbps, when more users access to the network equipment, a base station controller according to actual network, speech encoding techniques using AMRC of 64kbps rate is decreased to 12. 2kbps (as a second speech coding rate), the most appropriate rate to ensure optimal voice call quality. 其中,基站控制器也可以利用宽带自适应多速率编码技术(Wide-band Adaptivecoder With Multiple Rates),将用于与第一用户设备和第二用户设备建立用户面承载的语音编码速率改成第二语音编码速率,不影响本发明的实现。 Wherein the base station controller can also use adaptive multi-rate wideband coding technique (Wide-band Adaptivecoder With Multiple Rates), it will be used to establish a user plane bearer to the first user device and the second user device into a second rate speech encoder speech coding rate, without affecting the implementation of the invention.

[0069] 在现有网络中,某些情况下,需要对CS域的呼叫进行监听,由核心网侧的监听中心下达监听命令给MSC, MSC启动呼叫监听,将所述监听命令所指定用户的呼叫业务都传送到监听中心。 [0069] In existing networks, in some cases, the need for CS domain call listening, listening issued by a central core network side monitor command to the MSC, MSC initiates a call to listen, the user monitor command specified call service are sent to the monitor center. 由于本发明实施例中,呼叫双方进行在基站控制器内本地交换,不再经过核心网,因此不能对进行本地交换的呼叫双方进行监听。 Since the embodiment, both locally switched calls within a base station controller, not through the core network, and therefore can not be locally switched calls both listening present invention. 如果需要对某个特殊的用户设备的呼叫进行监听,可以在MSC上设置该用户设备的标识(比如用户号码)为不启动本地交换的特殊用户设备标识,由MSC判断主叫UE和被叫UE是否都能启动本地交换,也就是判断主叫UE的标识和被叫UE的标识是否是不启动本地交换的用户设备标识,如果主叫UE和被叫UE中任一个不能启动本地交换,上述步骤212中的RAB指配消息中不包括本地交换信息,主叫UE和被叫UE通过MSC进行数据交换,如果主叫UE和被叫UE都能启动本地交换,继续执行步骤212。 If a call is required to listen to a particular user device, the user can set the identifier of the device (such as a user number) on the MSC for the particular user equipment identifier does not start a local exchange MSC is determined by the calling UE and the called UE if the local exchange can be started, i.e. judges whether the called UE identifier and the identifier of the calling UE user equipment identifier is not the start of the local exchange, if any calling UE and the called UE can not start a local exchange, the above-described step 212 RAB assignment message does not include information about the local exchange, the calling UE and the called UE data exchange via the MSC, if the calling UE and the called UE can start a local exchange, proceed to step 212.

[0070] 在上述本发明实施例一步骤212中MSC向RNC发送的RAB指配消息中通常带有RAB分配的用于建立用户面承载的地址字段,对于本发明实施例可以忽略RAB分配的地址字段,不再为被叫建立IU 口用户面承载。 Example Step a [0070] The MSC sends the RAB assignment to the RNC 212 with the RAB assignment message commonly used to establish a user plane bearer address field of the present invention, in the above, embodiments of the present invention to be ignored in the address RAB Assignment field, it no longer carries the called user plane establishment IU port.

[0071] 本发明实施例二提供一种本地交换的方法,可以适用于UMTS PS域业务,用于支持分组数据业务和一些多媒体业务,使位于同一个RNC下的第一UE和第二UE间的用户面数据交换在本地实现,该方法具体包括: It provides a local switching according to the second embodiment of the method of [0071] the present invention can be applied to UMTS PS domain service, to support a number of packet data service and multimedia service that is located at the first UE and the second UE with an inter RNC the user plane data exchange implemented locally, the method comprises:

[0072] 步骤301、当GGSN确定第一UE和第二UE位于同一个SGSN下时,向SGSN发送本地交换查询消息。 [0072] Step 301, when the GGSN determining a first and second UE located in the same SGSN, the SGSN sends the local exchange inquiry message.

[0073] 步骤302、SGSN接收到本地交换查询消息后,判断第一UE和第二UE是否位于同一 After [0073] Step 302, SGSN receives the query message to the local exchange determines a first and second UE are on the same

个RNC下,如果是,执行步骤303。 The next RNC, if yes, step 303. 如果否,后续流程与现有技术相同,结束本流程。 If not, the prior art processes follow the same, the process ends.

[0074] 步骤303、 SGSN向RNC发送RAB指配消息,该消息中携带本地交换信息,本地交换 [0074] Step 303, SGSN transmits to the RNC RAB assignment message, which carries information on the local exchange, the local exchange

信息包括:本地交换指示(Local Switch)、第一UE的标识和第二UE的标识。 Information includes: a local switching indication (Local Switch), identifying the first UE and the second UE identity.

[0075] 步骤304、RNC配置第一UE数据转发地址是第二UE的地址;配置第二UE数据转发 [0075] Step 304, RNC UE configuration data forwarding address is a first address of the second UE; UE data forwarding a second configuration

地址是第一UE的地址。 Address is the address of the first UE.

[0076] 步骤305、RNC接收来自第一UE的数据。 [0076] Step 305, RNC receives the data from the first UE.

[0077] 步骤306、 RNC根据第一UE数据转发地址,将来自第一UE的数据转发到第二UE。 [0077] Step 306, RNC forwards the data address according to the first UE, forwarding data from the first UE to the second UE. [0078] 步骤307、RNC接收来自第二UE的数据。 [0078] Step 307, RNC receives the data from the second UE.

[0079] 步骤308、RNC根据第二UE数据的转发地址,将来自第二UE的数据转发到第一UE。 [0079] Step 308, RNC according to the data forwarding address of the second UE, the second UE from the data forwarded to the first UE. [0080] 由于在步骤301之前,第一UE和第二UE已经建立了PS业务,因此已经为第一UE和第二UE建立了IU 口用户面承载;因此,该方法还可以包括:释放为主叫UE建立的Iu 口用户面承载,释放为被叫UE建立的Iu 口用户面承载。 [0080] Since prior to step 301, the first and second UE has established the PS service, and therefore has established a user plane for the first port IU and second UE bearer; therefore, the method may further comprise: releasing as the calling UE establishes an Iu interface user plane bearer release Iu interface user plane is established for the called UE bearer.

[0081 ] 在UE与UTRAN之间的RRC连接建立成功后,UE通过RNC建立与CN之间的信令连接,也叫非接入层(Non-Access Stratum, NAS)信令连接,用于交互NAS信息,如鉴权等。 A signaling connection between the [0081] After the RRC connection between the UE and the UTRAN connection is established, the UE by the RNC establishes CN, also called NAS (Non-Access Stratum, NAS) signaling connection for interactive NAS information, such as authentication and the like. 上述两个实施例仍然保持UE与CN间的NAS信令连接,非接入层信令仍然由核心网处理。 The above two embodiments remains NAS signaling connection between the UE and the CN, remain non-access stratum signaling processed by the core network. [0082] 如果一个用户设备同时进行CS域业务和PS域业务,可以分别按照本发明实施例一和本发明实施例二所提供的技术方案进行处理;对于CS域的业务,如果要进行本地交换,在步骤212中MSC向RNC发送的无线接入承载RAB指配消息中携带本地交换信息;对于PS域的业务,如果要进行本地交换,在步骤303中SGSN向RNC发送的RAB指配消息中携带本地交换信息。 [0082] If a user equipment simultaneously the CS domain service and the PS domain service, may each embodiment according to the present invention a and the technical solutions according to the second embodiment of the present invention provides for processing; for the service of the CS domain, if local switching , wireless access in step 212 sent by the MSC to the RNC bearer (RAB) assignment message carries the local exchange of information; for PS domain service, if local switching, at step 303 SGSN sends a RAB the assignment message to the RNC carry local exchange of information.

[0083] —个UTRAN可以包括一个或者多个无线网络子系统(Radio NetworkSubsystem,RNS),而一个RNS又包括:基站NodeB和RNC。 [0083] - a UTRAN may include one or more radio network subsystems (Radio NetworkSubsystem, RNS), while an RNS in turn comprising: a base station NodeB and RNC. 如果在一个UE与UTRAN的连接中用到了超过一个RNS的无线资源,那么这些涉及的RNC具有两个独立的逻辑功能:[0084] 1、服务RNC(SRNC):管理UE和UTRAN之间的无线连接,是对应于该UE的Iu接口的终止点。 If the radio resources used in more than one RNS is connected in a UE and the UTRAN, then the RNC according to having two separate logical functions: [0084] 1, the service RNC (the SRNC): manage a wireless connection between the UE and the UTRAN connector, corresponding to the termination point of the Iu interface to the UE. 无线接入承载的参数映射到传输信道的参数、是否进行越区切换、开环功率控制等基本的无线资源管理都是由SRNC来完成的。 Radio access bearer parameters mapped to the transport channel parameters, whether the handover, open loop power control basic radio resource management is done by the SRNC. 一个与UTRAN相连的UE有且只能有一个SRNC。 A UE and UTRAN connected to one and only one SRNC.

[0085] 2、漂移RNC(DRNC):在RNC之间的软切换需要第二个RNC参与,这个RNC为UE提供资源称为DRNC ; [0085] 2, the drift RNC (DRNC): the need for a second RNC soft handover between the RNC involvement, the RNC provides the resources for the UE is called the DRNC;

[0086] 通常在实际的RNC中包含了SRNC和DRNC的功能。 [0086] SRNC and DRNC typically contains the actual functions of the RNC.

[0087] 上述本发明实施例一的介绍已实现本发明的目的,对于本发明实施例一所提供的主叫UE和被叫UE在RNC内进行本地交换的过程中,当其中一方跨RNC切换时,本地交换不能够再进行,图4示出了UMTS CS域中UE跨RNC切换伴随迁移流程图,假定主叫UE跨RNC切换,切换过程具体包括: Process Embodiment [0087] The above described embodiment of the present invention, one object of the present invention has been achieved, the local switching is in the RNC for one embodiment of the calling UE and the called UE provided by the embodiment of the present invention, wherein when the inter-RNC handover party when the local exchange can not be performed again, FIG. 4 shows a UMTS UE CS domain RNC handover across mobility accompanying flowchart, assume that the calling UE inter-RNC handover, the handover procedure comprises:

[0088] 步骤401、主叫UE向服务RNC (SRNC)发送测量报告。 [0088] Step 401, the calling UE sends a measurement report to the serving RNC (SRNC).

[0089] 步骤402、 SRNC根据测量报告获知主叫UE需要外迁到其他RNC,本地交换不能再 [0089] Step 402, SRNC needs to know the calling UE relocated to another RNC according to the measurement report, the local exchange can not

进行,SRNC为主叫UE建立IU 口用户面承载;为被叫UE建立IU 口用户面承载。 Performed, SRNC calling UE establishes a user plane bearer IU port; IU port establishing the user plane bearer to the called UE.

[0090] 该步骤中SRNC可以不用为主叫UE建立IU 口用户面承载,不影响本发明的实现。 [0090] In this step SRNC calling UE can not establish a user plane bearer IU port, it does not affect the implementation of the invention.
