背景技术Background technique
随着长期演进(Long Term Evolution,LTE)网络技术的不断成熟，用户越来越倾向于使用LTE制式的用户识别模块(Subscriber Identity Model,SIM)卡，同时，现在的用户终端(User Equipment,UE)通常具有双卡双待的功能，因此，通常用户终端UE可以同时安装有LTE制式的卡和普通第二代移动通信技术(2rd-generation,2G)/第三代移动通信技术(3rd-generation,3G)网络制式的卡，LTE制式的卡主要用于处理分组交换(Packet Switch，PS)域上的数据业务，普通2G/3G制式的卡主要用于处理电路交换(Circuit Switched，CS)域上的语音业务。从而为用户带来更加便利的服务。With the continuous maturity of Long Term Evolution (LTE) network technology, users are more and more inclined to use LTE standard Subscriber Identity Module (Subscriber Identity Model, SIM) card. At the same time, the current User Equipment (UE ) usually has the function of dual-card dual-standby. Therefore, usually, the user terminal UE can be installed with an LTE-standard card and a common second-generation mobile communication technology (2rd-generation, 2G)/third-generation mobile communication technology (3rd-generation , 3G) network standard card, LTE standard card is mainly used to process data services on the packet switching (Packet Switch, PS) domain, ordinary 2G/3G standard card is mainly used to process circuit switching (Circuit Switched, CS) domain Voice services on the Internet. So as to bring more convenient services to users.
现有技术中，LTE网络中通常采用的是电路域回落(Circuit SwitchedDomain Fall Back，CSFB)技术，该CSFB技术实现用户终端UE在LTE网络接入下不能够发起和接收语音业务，LTE网络回退到2G/3G网络来处理CS域的语音业务，并且能够对用户终端UE在LTE网络接入下正在进行的数据业务进行正确的处理。In the prior art, the Circuit Switched Domain Fall Back (CSFB) technology is usually adopted in the LTE network. This CSFB technology realizes that the user terminal UE cannot initiate and receive voice services under the access of the LTE network, and the LTE network falls back. Go to the 2G/3G network to process the voice service of the CS domain, and can correctly process the ongoing data service of the user terminal UE under the access of the LTE network.
然而，现有技术存在如下问题：在用户终端UE在LTE卡上存在PS域上的数据业务的情况下，若这时存在其它用户终端寻呼本用户终端UE时，那么本用户终端UE触发LTE网络回退到了2G/3G网络处理CS域的语音业务，若回退后的网络不支持数据业务，因此，对于那些在LTE网络下进行的数据业务只能被挂起或者中断，从而降低了通信网络的可靠性。However, the existing technology has the following problem: when the user terminal UE has data services on the PS domain on the LTE card, if there are other user terminals paging the user terminal UE, the user terminal UE triggers the LTE The network falls back to the 2G/3G network to handle voice services in the CS domain. If the network after the rollback does not support data services, the data services carried out under the LTE network can only be suspended or interrupted, thereby reducing communication network reliability.

具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
图1为本发明一实施例提供的一种业务接入方法的流程图，该方法适用于用户终端UE双卡双待的场景，其中该方法的执行主体为移动管理实体MME，该方法具体包括如下流程：Figure 1 is a flow chart of a service access method provided by an embodiment of the present invention, the method is applicable to the scenario of dual card dual standby of the user terminal UE, wherein the subject of execution of the method is the mobile management entity MME, and the method specifically includes The following process:
S101：移动管理实体MME接收第一用户终端UE上的第一SIM卡发送的业务状态消息；S101: The mobility management entity MME receives a service status message sent by the first SIM card on the first user terminal UE;
具体地，所述业务状态消息携带第一SIM卡的数据业务状态，这里的第一SIM卡为LTE制式的卡，主要用于处理分组交换PS域上的数据业务。数据业务状态包括：开启状态和关闭状态。其中，所谓开启状态为：数据业务程序正在前台或者后台运行。比如：用户正在通过第一SIM卡浏览搜狐网页，该搜狐网页就是一项数据业务，它的对应程序正在前台运行，因此，这项数据业务状态为开启状态。所谓关闭状态为：数据业务程序既未在前台运行，也未在后台运行。Specifically, the service state message carries the data service state of the first SIM card, where the first SIM card is a card of the LTE standard, and is mainly used for processing data services on the packet switching PS domain. The data service state includes: on state and off state. Wherein, the so-called open state is: the data service program is running in the foreground or in the background. For example: the user is browsing the Sohu webpage through the first SIM card, the Sohu webpage is a data service, and its corresponding program is running in the foreground, therefore, the state of this data service is enabled. The so-called closed state is: the data service program is neither running in the foreground nor running in the background.
S102：若所述数据业务状态为开启状态，且当MME接收到第二UE向第一SIM卡发送的寻呼消息时，则MME将寻呼消息发送给第一UE上的第二SIM卡。S102: If the data service status is enabled, and when the MME receives the paging message sent by the second UE to the first SIM card, the MME sends the paging message to the second SIM card on the first UE.
具体地，这里的第二SIM卡通常为普通的2G/3G制式的卡，通常主要用于处理CS域上的语音业务。本发明中的第一UE为被叫方，第二UE为主叫方，为了解决现有技术中由于第二UE寻呼第一UE的第一SIM卡时，所造成第一SIM卡上的数据业务被挂起或者中断的技术问题。本实施例中提出：若第一SIM卡上的数据业务状态为开启状态，则当UE在第一SIM卡上接收到第二UE发送的寻呼消息时，即在第一SIM卡上存在电路交换CS域上的语音业务时，则MME将寻呼消息发送给第二SIM卡。从而使得第一SIM卡上的数据业务无需挂起或者中断。Specifically, the second SIM card here is usually a common 2G/3G standard card, and is usually mainly used to process voice services on the CS domain. In the present invention, the first UE is the called party, and the second UE is the calling party. In order to solve the problems on the first SIM card caused by the second UE paging the first SIM card of the first UE in the prior art, A technical problem in which data services are suspended or interrupted. In this embodiment, it is proposed that if the data service status on the first SIM card is enabled, when the UE receives the paging message sent by the second UE on the first SIM card, there is a circuit on the first SIM card. When exchanging voice services on the CS domain, the MME sends a paging message to the second SIM card. Therefore, the data service on the first SIM card does not need to be suspended or interrupted.
本实施例提供了一种业务接入方法，包括：移动管理实体MME接收第一UE发送的业务状态消息，其中业务状态消息携带UE上的第一SIM卡的数据业务状态；若数据业务状态为开启状态，且当MME接收到第二UE向第一SIM卡发送的寻呼消息时，则MME将寻呼消息发送给第二SIM卡。即将第一SIM卡上的语音业务转接入至第二SIM卡上，从而避免了现有技术中当UE在第一SIM卡上存在CS域上的语音业务时，造成第一SIM卡上的数据业务被挂起或者终端的问题，进而提高了通信网络的可靠性。This embodiment provides a service access method, including: a mobile management entity MME receives a service status message sent by a first UE, wherein the service status message carries the data service status of the first SIM card on the UE; if the data service status is In the ON state, and when the MME receives the paging message sent by the second UE to the first SIM card, the MME sends the paging message to the second SIM card. That is, the voice service on the first SIM card is transferred to the second SIM card, thereby avoiding the voice service on the first SIM card when the UE has a voice service on the CS domain on the first SIM card in the prior art. Data services are suspended or terminated, thereby improving the reliability of the communication network.
图2为本发明另一实施例提供的一种业务接入方法的流程图，本实施例在上一实施例的基础上，进一步地提供了通信网络中的多个网元的交互流程，其中业务接入方法具体包括：Fig. 2 is a flow chart of a service access method provided by another embodiment of the present invention. On the basis of the previous embodiment, this embodiment further provides an interaction process of multiple network elements in a communication network, wherein Service access methods specifically include:
S201：第一SIM卡与MME之间建立LTE网络附着过程。S201: An LTE network attachment process is established between the first SIM card and the MME.
S202：第二SIM卡与移动交换中心1(Mobile Switching Center1，MSC1)之间建立2G/3G网络附着过程。S202: A 2G/3G network attachment process is established between the second SIM card and a mobile switching center 1 (Mobile Switching Center1, MSC1).
S203：第一SIM卡向第一基站发送第二SIM卡消息。S203: The first SIM card sends a second SIM card message to the first base station.
S204：第一基站向MME发送第二SIM卡消息。S204: The first base station sends a second SIM card message to the MME.
S205：MME判断第一SIM卡和第二SIM卡是否属于同一个UE。S205: The MME judges whether the first SIM card and the second SIM card belong to the same UE.
S206：第一SIM卡向第一基站发送第一SIM卡的业务状态消息。S206: The first SIM card sends a service status message of the first SIM card to the first base station.
S207：第一基站向MME发送第一SIM卡的业务状态消息。S207: The first base station sends a service status message of the first SIM card to the MME.
S208：MME接收第二UE所在的移动交换中心MSC2发送的对第一SIM卡的寻呼消息。S208: The MME receives a paging message for the first SIM card sent by the mobile switching center MSC2 where the second UE is located.
S209：若第一SIM卡的数据业务状态为开启状态，MME发送第二SIM卡消息给MSC2。S209: If the data service status of the first SIM card is enabled, the MME sends a second SIM card message to MSC2.
S210：MSC2根据第二SIM卡的IMSI信息向归属位置寄存器(HomeLocation Register,HLR)发送建立呼叫请求消息。S210: MSC2 sends a call establishment request message to a home location register (HomeLocation Register, HLR) according to the IMSI information of the second SIM card.
S211：HLR向MSC2发送建立呼叫响应消息。S211: The HLR sends a call establishment response message to MSC2.
S212：MSC2与第二SIM卡所在的2G/3G网络之间建立呼叫连接。S212: Establish a call connection between MSC2 and the 2G/3G network where the second SIM card is located.
具体地，在移动管理实体MME接收第一SIM卡发送的第一SIM卡的业务状态消息之前，MME接收第二SIM卡消息，其中，第二SIM卡消息携带第二SIM卡的国际移动用户识别码(International Mobile SubscriberIdentification Number，IMSI)信息。当然第二SIM卡消息也可以携带第一SIM卡的IMSI信息，MME会获取第一UE的移动设备国际身份码(InternationalMobile Equipment Identity，IMEI)，由于每个UE的IMEI是唯一的，因此MME可以根据第一SIM卡的IMSI信息与第二SIM卡的IMSI信息是否对应于同一个IMEI，来判断第一SIM卡和第二SIM卡是否属于同一个UE。若MME判断第一SIM卡和第二SIM卡同属于一个UE，则MME接收第一UE发送的第一SIM卡的业务状态消息，其中，所述业务状态消息携带所述UE上的第一SIM卡的数据业务状态；数据业务状态包括：开启状态和关闭状态。Specifically, before the mobility management entity MME receives the service status message of the first SIM card sent by the first SIM card, the MME receives the second SIM card message, wherein the second SIM card message carries the international mobile subscriber identity of the second SIM card Code (International Mobile Subscriber Identification Number, IMSI) information. Of course, the second SIM card message can also carry the IMSI information of the first SIM card, and the MME will obtain the International Mobile Equipment Identity (IMEI) of the first UE. Since the IMEI of each UE is unique, the MME can Whether the first SIM card and the second SIM card belong to the same UE is determined according to whether the IMSI information of the first SIM card and the IMSI information of the second SIM card correspond to the same IMEI. If the MME judges that the first SIM card and the second SIM card belong to the same UE, the MME receives the service status message of the first SIM card sent by the first UE, wherein the service status message carries the first SIM card on the UE The data service state of the card; the data service state includes: open state and closed state.
进一步地，当MME接收到第二UE所在的移动交换中心MSC2发送的寻呼消息，其中，该寻呼消息携带所述第一SIM卡的IMSI信息，即第二UE是向第一SIM卡发送寻呼消息，这时若第一SIM卡的数据业务状态为开启状态，MME将寻呼消息发送给所述第二SIM卡。Further, when the MME receives the paging message sent by the mobile switching center MSC2 where the second UE is located, where the paging message carries the IMSI information of the first SIM card, that is, the second UE sends the paging message to the first SIM card A paging message. At this time, if the data service status of the first SIM card is enabled, the MME sends the paging message to the second SIM card.
其中，MME将寻呼消息发送给所述第二SIM卡，具体包括：MME发送第二SIM卡消息给第二UE，以使第二UE根据IMSI信息建立与第二SIM卡所在网络的呼叫连接。第二UE根据IMSI信息建立与第二SIM卡所在网络的呼叫连接，具体为：MSC2解析第二SIM卡消息，获取第二SIM卡的IMSI信息。这时MSC2将发送的寻呼消息中所携带的第一SIM卡的IMSI信息修改为第二SIM卡的IMSI信息。从而实现将寻呼消息发送给第二SIM卡，而不是发送给第一SIM卡。Wherein, the MME sending the paging message to the second SIM card specifically includes: the MME sending the second SIM card message to the second UE, so that the second UE establishes a call connection with the network where the second SIM card is located according to the IMSI information . The second UE establishes a call connection with the network where the second SIM card is located according to the IMSI information. Specifically, the MSC2 parses the message of the second SIM card to obtain the IMSI information of the second SIM card. At this time, MSC2 modifies the IMSI information of the first SIM card carried in the sent paging message to the IMSI information of the second SIM card. Therefore, it is realized that the paging message is sent to the second SIM card instead of the first SIM card.
可选地，若所述数据业务状态为关闭状态，则当所述第一UE在第一SIM卡上存在CS域上的语音业务时，所述MME将所述语音业务接入所述第一UE的第一SIM卡上。Optionally, if the data service status is off, when the first UE has voice services in the CS domain on the first SIM card, the MME accesses the voice services to the first SIM card. on the first SIM card of the UE.
本实施例提供了一种业务接入方法，包括：第一UE向MME发送第二SIM卡消息，MME判断第一SIM卡和第二SIM卡是否属于同一个UE，MME接收第一SIM卡发送的业务状态消息，若数据业务状态为开启状态，且当所述MME接收到第二UE向所述第一SIM卡发送的寻呼消息时，则所述MME将所述寻呼消息发送给所述第二SIM卡。从而避免了现有技术中当第一UE在第一SIM卡上存在CS域上的语音业务时，造成第一SIM卡上的数据业务被挂起或者终端的问题，进而提高了通信网络的可靠性。This embodiment provides a service access method, including: the first UE sends a second SIM card message to the MME, the MME judges whether the first SIM card and the second SIM card belong to the same UE, and the MME receives the information sent by the first SIM card. If the data service status is enabled, and when the MME receives the paging message sent by the second UE to the first SIM card, the MME sends the paging message to the the second SIM card. Therefore, in the prior art, when the first UE has a voice service in the CS domain on the first SIM card, the data service on the first SIM card is suspended or terminated, thereby improving the reliability of the communication network sex.
