Description
技术领域technical field
本发明涉及通信技术领域,尤其涉及一种语音业务接入方法及设备。The present invention relates to the technical field of communication, in particular to a voice service access method and equipment.
背景技术Background technique
长期演进(Long Term Evolution,简称LTE)的网络架构不再区分电路域和分组域,采用统一的分组域架构,因此它不再支持传统的电路域语音业务。目前,为了保证LTE网络中的语音业务,诞生了多模双待、退回电路交换(CircuitSwitched Fallback,简称CSFB)业务和基于长期演进的语音业务(Voice overLTE,简称VoLTE)。The network architecture of Long Term Evolution (LTE for short) no longer distinguishes between circuit domain and packet domain, and adopts a unified packet domain architecture, so it no longer supports traditional circuit domain voice services. At present, in order to ensure the voice service in the LTE network, multi-mode dual standby, circuit switched fallback (CSFB for short) service and voice service based on long-term evolution (Voice over LTE, VoLTE for short) have been born.
CSFB语音业务,其技术的思想是在进行LTE覆盖下的用户终端(UserEquipment,简称UE)在处理语音业务时,终端先回退到电路域(CS)网络,在CS网络处理语音业务,达到了重用现有的CS域设备来为LTE网络中的UE提供传统的语音业务的目的。CSFB voice service, the technical idea is that when a user equipment (UE) under LTE coverage processes voice services, the terminal first falls back to the circuit domain (CS) network, and processes voice services on the CS network, achieving The purpose of reusing existing CS domain equipment to provide traditional voice services for UEs in the LTE network.
VoLTE语音业务是基于LTE网络的语音业务,即全部业务承载于LTE网络上,无需2G/3G网,可实现数据与语音业务在同一网络下的统一。其核心业务控制网络是IMS(IP多媒体子系统)网络,配合LTE和分组核心演进(Evolved PacketCore,简称EPC)网络实现端到端的基于分组域的语音、视频通信业务。通过IMS系统的控制,VoLTE解决方案可以提供和电路域性能相当的语音业务及其补充业务,包括:号码显示、呼叫转移、呼叫等待、会议电话等。The VoLTE voice service is a voice service based on the LTE network, that is, all services are carried on the LTE network, without the need for a 2G/3G network, and can realize the unification of data and voice services under the same network. Its core business control network is an IMS (IP Multimedia Subsystem) network, which cooperates with LTE and Evolved Packet Core (EPC) network to realize end-to-end voice and video communication services based on the packet domain. Through the control of the IMS system, the VoLTE solution can provide voice services and supplementary services comparable to the performance of the circuit domain, including: number display, call transfer, call waiting, conference calls, etc.
相比较CSFB业务,VoLTE语音业务具有以下优点:Compared with CSFB service, VoLTE voice service has the following advantages:
第一、VoLTE能够带来更好的使用感受和更佳的用户体验,高清语音和视频编解码的引入将语音通话质量提升2倍,VoLTE的呼叫接续时长大幅缩短,VoLTE能将高清语音业务与IMS(IP多媒体子系统)网络具有的其他多媒体业务(如融合消息、会议、视频共享等)以及互联网业务进行有机融合,从而提供远比窄带语音业务丰富的融合业务体验。First, VoLTE can bring better experience and better user experience. The introduction of high-definition voice and video codec can improve the quality of voice calls by 2 times, and the call connection time of VoLTE can be greatly shortened. The IMS (IP Multimedia Subsystem) network has organic integration of other multimedia services (such as converged messaging, conferencing, video sharing, etc.) and Internet services to provide a richer experience of converged services than narrowband voice services.
第二、VoLTE基于LTE承载语音,能够充分利用LTE无线技术高频谱利用率、抗衰落性、高带宽、大容量的优点。Second, VoLTE is based on LTE to carry voice, and can make full use of the advantages of LTE wireless technology's high spectrum utilization, anti-fading, high bandwidth, and large capacity.
第三、VoLTE网络性能高于现网,其接续时间相比2G/3G网络可提高50%以上”。Third, the performance of the VoLTE network is higher than that of the existing network, and its connection time can be increased by more than 50% compared with the 2G/3G network."
第四、VoLTE真正实现端到端IP语音业务,符合网络演进方向,方案简单。”Fourth, VoLTE truly realizes end-to-end IP voice services, conforms to the direction of network evolution, and has a simple solution. "
现有技术语音用户的接入方式是,根据UE支持的语音业务类型,并结合当前该用户所在位置的运营商的语音业务技术的部署情况,选择VoLTE或CSFB进行语音业务。;例如根据Voice domain preference for E-UTRAN字段所定义的用户支持或优先支持语音业务的类型,并结合当前该用户所在位置的运营商的语音业务技术的部署情况,选择VoLTE或CSFB进行语音业务。In the prior art, the voice user access method is to select VoLTE or CSFB for the voice service according to the voice service type supported by the UE and in combination with the current deployment of the voice service technology of the operator where the user is located. ; For example, according to the type of user support or priority support for voice services defined in the Voice domain preference for E-UTRAN field, and in combination with the current deployment of the operator's voice service technology at the user's location, VoLTE or CSFB is selected for voice services.
当用户支持或优先支持VoLTE业务,且当前网络支持VoLTE业务,选择VoLTE业务进行语音业务的接入。When the user supports or preferentially supports the VoLTE service, and the current network supports the VoLTE service, select the VoLTE service for voice service access.
当前LTE网络中的语音业务方案存在以下问题:The voice service solution in the current LTE network has the following problems:
1、当国外漫入用户发起语音业务时,当国外运营商不支持VoLTE业务,而国内有运营商支持VoLTE业务时,而用户终端支持CSFB和VoLTE业务时,该用户可能用VoLTE进行语音业务,这会造成该用户的通话中断,影响用户体验。所述国外漫入用户为归属地为国外且在本国进行语音业务的用户。2、对于国内同时部署了VoLTE和CSFB的区域,若UE定义为优先选择CSFB业务,则用户将不会采用VoLTE技术进行语音业务,这使得VoLTE的优越性不能充分体现。3、运营商无法根据自己的实际情况定制语音通信的方案,不利于用户向LTE的迁移。1. When a foreign roaming user initiates a voice service, when the foreign operator does not support the VoLTE service, but a domestic operator supports the VoLTE service, and the user terminal supports CSFB and VoLTE services, the user may use VoLTE for the voice service, This will cause the user's call to be interrupted, affecting user experience. The foreign roaming-in user is a user who belongs to a foreign country and performs voice services in the home country. 2. For areas where both VoLTE and CSFB are deployed in China, if the UE is defined as preferentially selecting CSFB services, users will not use VoLTE technology for voice services, which makes the superiority of VoLTE not fully reflected. 3. Operators cannot customize voice communication solutions according to their actual conditions, which is not conducive to users' migration to LTE.

The MME determines the attribution of the user terminal according to the pre-stored attribution information of the user terminal, where the attribution information is at least used to indicate that the user terminal is a foreign roaming user or a domestic user;
S13、当所述用户终端为国外漫入用户时,MME通过退回电路交换CSFB业务实现所述语音业务的接入。S13. When the user terminal is a foreign roaming user, the MME implements the voice service access by returning the CSFB service.
所述国外漫入用户为归属地为国外且在本国进行语音业务的用户。The foreign roaming-in user is a user who belongs to a foreign country and performs voice services in the home country.

进一步地,当所述用户终端为国内用户时,MME根据当前网络部署类型以及用户终端的能力,确定选择哪一种类型的语音业务将用户终端接入网络。Further, when the user terminal is a domestic user, the MME determines which type of voice service to select to connect the user terminal to the network according to the current network deployment type and the capability of the user terminal.
参见图2,以下将具体说明本发明实施例提供的语音业务接入方法。Referring to FIG. 2 , the voice service access method provided by the embodiment of the present invention will be described in detail below.
S101、MME接收来自用户终端的附着请求,该附着请求中携带有所述用户终端的归属地信息;以及携带有用于表征所述用户终端支持的语音业务类型信息,存储所述归属地信息以及用户终端支持的语音业务类型信息。S101. The MME receives an attach request from the user terminal, the attach request carries the attribution information of the user terminal; and carries voice service type information used to characterize the support of the user terminal, stores the attribution information and the user Voice service type information supported by the terminal.
例如,所述归属地为国外漫入用户或国内用户。所述语音业务类型包括:用户终端仅支持CSFB业务、用户终端仅支持VoLTE业务、用户终端同时支持CSFB业务和VoLTE业务。For example, the attribution is an overseas roaming user or a domestic user. The voice service type includes: the user terminal only supports CSFB service, the user terminal only supports VoLTE service, and the user terminal supports both CSFB service and VoLTE service.
进一步地,当用户终端同时支持CSFB业务和VoLTE业务时,还可以标识启用某一业务的优先级。Further, when the user terminal supports the CSFB service and the VoLTE service at the same time, the priority for enabling a certain service may also be identified.
具体地,MME接收来自用户终端的附着请求,该附着请求中携带有所述用户终端的归属地信息PLMN和语音域优先选择Voice domain preference forE-UTRAN字段信息;定义字段为00时,表示用户终端只支持电路域的语音业务,即仅支持CSFB业务;定义字段为01时,表示用户终端只支持分组域的语音业务,即仅支持VoLTE业务;定义字段为10时,优先选择电路域提供语音业务,分组域为备选;定义字段为11时,优先选择分组域进行语音业务,电路域作为备选。Specifically, the MME receives an attach request from the user terminal, which carries the attribution information PLMN of the user terminal and the Voice domain preference for E-UTRAN field information; when the definition field is 00, it means that the user terminal Only supports voice services in the circuit domain, that is, only supports CSFB services; when the definition field is 01, it means that the user terminal only supports voice services in the packet domain, that is, only supports VoLTE services; when the definition field is 10, the voice service is preferentially selected in the circuit domain , the packet domain is an option; when the definition field is 11, the packet domain is preferred for voice services, and the circuit domain is an option.
S102、MME接收用户终端的语音业务接入请求;S102. The MME receives the voice service access request of the user terminal;
S103、MME根据所述预先存储的该用户终端的归属地信息判断所述用户终端的归属地,所述归属地信息至少用于表征所述用户终端为国外漫入用户或国内用户;S103. The MME determines the attribution of the user terminal according to the pre-stored attribution information of the user terminal, where the attribution information is at least used to indicate that the user terminal is a foreign roaming user or a domestic user;
当所述用户终端为国外漫入用户时,执行步骤S107,否则(即为国内用户)执行步骤S104;When the user terminal is a foreign roaming user, execute step S107, otherwise (that is, a domestic user) execute step S104;
S104、MME判断当前网络是否支持基于长期演进的语音VoLTE业务,如果当前网络不支持基于长期演进的语音VoLTE业务,执行步骤S107;否则执行步骤S105;所述当前网络为所述MME所在的网络。S104, the MME judges whether the current network supports voice VoLTE services based on long-term evolution, and if the current network does not support voice VoLTE services based on long-term evolution, perform step S107; otherwise perform step S105; the current network is the network where the MME is located.
S105、判断所述用户终端支持的语音业务类型;如果所述用户终端仅支持电路域的语音业务,则执行步骤S107,如果用户终端支持分组域的语音业务,无论其是否支持电路域的语音业务,则执行步骤S106;S105.

判断所述用户终端支持的语音业务类型可以通过判断语音域优先选择Voice domain preference for E-UTRAN字段信息实现。例如,当所述Voice domainpreference for E-UTRAN字段信息为00时,则执行步骤S107;当所述Voicedomain preference for E-UTRAN字段信息为01、10、或11时,则执行步骤S106。实现了优选根据用户归属地,以及运营商网络的部署情况,结合移动终端的设置确定语音通信方案。对于VoLTE部署规模较完善的区域,优先采用VoLTE技术进行语音业务。避免了营运商部署了VoLTE的区域,且用户终端支持VoLTE功能时,仍然通过CSFB实现语音业务的接入导致资源的浪费,且导致语音体验效果较差的问题。Judging the voice service type supported by the user terminal may be realized by judging the Voice domain preference for E-UTRAN field information. For example, when the Voice domain preference for E-UTRAN field information is 00, then perform step S107; when the Voice domain preference for E-UTRAN field information is 01, 10, or 11, then perform step S106. It realizes preferably determining the voice communication scheme according to the location of the user and the deployment situation of the operator's network in combination with the setting of the mobile terminal. For areas with relatively complete VoLTE deployment scale, VoLTE technology is preferred for voice services. It avoids the problem that operators have deployed VoLTE in areas and user terminals support VoLTE functions, but CSFB is still used to implement voice service access, resulting in waste of resources and poor voice experience.
S106、通过基于长期演进的语音VoLTE业务实现所述语音业务的接入。S106. Realize access to the voice service through the voice VoLTE service based on long-term evolution.
由于VoLTE语音方案是运营商的终极解决方案。VoLTE的核心业务控制网络是IMS(IP多媒体子系统)网络,配合LTE和EPC网络实现端到端的基于分组域的语音、视频通信业务。通过IMS系统的控制,VoLTE解决方案可以提供和电路域性能相当的语音业务及其补充业务,包括:号码显示、呼叫转移、呼叫等待、会议电话等。本发明在VoLTE部署规模较完善的区域,优先采用VoLTE技术进行语音业务,充分利用了VoLTE的优越性。Because the VoLTE voice solution is the ultimate solution for operators. The core service control network of VoLTE is the IMS (IP Multimedia Subsystem) network, which cooperates with LTE and EPC networks to realize end-to-end voice and video communication services based on the packet domain. Through the control of the IMS system, the VoLTE solution can provide voice services and supplementary services comparable to the performance of the circuit domain, including: number display, call transfer, call waiting, conference calls, etc. In the area where the VoLTE deployment scale is relatively complete, the present invention preferentially adopts the VoLTE technology for voice services, and makes full use of the advantages of the VoLTE.
S107、通过退回电路交换CSFB业务实现所述语音业务的接入。S107. Realize the voice service access by returning the CSFB service.
通过退回电路交换CSFB业务实现所述语音业务的接入,以及通过VoLTE业务实现所述语音业务的接入与现有技术接入语音业务的方式类似,这里不再赘述。Implementing the access of the voice service by returning the CSFB service, and implementing the access of the voice service by using the VoLTE service are similar to the way of accessing the voice service in the prior art, and will not be repeated here.
