Description

一种业务切换方法及相关设备Service switching method and related equipment

技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种业务切换方法及相关设备。The present invention relates to the field of communications technologies, and in particular, to a service switching method and related devices.

背景技术Background technique

在移动通信***中，多终端共享号码功能是指支持一个手机号码对应多张用户识别卡(Subscriber Identify Module，SIM)或全球用户识别卡(UMTS Subscriber Identify Module，USIM)，每张卡对应不同的国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI标识)。实际生活中，用户可以在多个终端分别放入具备相同的手机号码的SIM卡或者USIM卡，例如，手机中放一张SIM卡、车载电话中放入一张SIM卡、可穿戴设备中放入一张SIM卡，并且用户可以指定各个终端可使用的业务类型，例如，语音业务、分组数据业务等。可以看出，虽然是多张卡，但用户只要管理这多张卡对应的一个手机号码的消费单据就可以了，方便用户使用。In the mobile communication system, the multi-terminal shared number function refers to supporting a mobile phone number corresponding to multiple Subscriber Identify Modules (SIMs) or UMTS Subscriber Identify Modules (USIMs), each card corresponding to a different one. International Mobile Subscriber Identification Number (IMSI). In real life, users can put SIM cards or USIM cards with the same mobile phone number in multiple terminals, for example, put a SIM card in the mobile phone, put a SIM card into the car phone, and put it in the wearable device. A SIM card is entered, and the user can specify the type of service that each terminal can use, such as voice service, packet data service, and the like. It can be seen that although there are multiple cards, the user only needs to manage the consumption documents of one mobile phone number corresponding to the multiple cards, which is convenient for the user to use.

而在实际应用中，用户在某些场合中会需要将正在执行的业务由一个终端变更到另一个终端中，例如，在用户使用车载电话进行通话的情况下，若用户需要离开车而导致无法继续使用车载电话通话时，用户会想在手机中继续通话，这时用户常常会先断开车载电话的通话，并用手机重新建立通话。但是这样操作的方式较为复杂，且存在通话中断，给用户带来诸多不便，降低了终端的便捷性和智能性。In practical applications, the user may need to change the running service from one terminal to another in some occasions. For example, if the user needs to leave the car when the user uses the car phone to make a call, the user cannot When you continue to use the car phone to talk, the user will want to continue the call in the phone, then the user often disconnects the car phone first, and re-establishes the call with the phone. However, the manner of operation is complicated, and there is a call interruption, which brings a lot of inconvenience to the user, and reduces the convenience and intelligence of the terminal.

Those skilled in the art will understand and implicitly understand that the embodiments described herein can be combined with other embodiments.

为了便于理解本发明，下面先介绍下本发明实施例适用的一种可能的网络架构图，如图1所示，是一个演进分组***(Evolved Packet System，EPS)网络架构图，包括用户设备(User Equipment，UE)、物联网(Internet of Things，IoT)设备、演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，E-UTRAN)、移动性管理实体(Mobility Management Entity，MME)、GPRS服务支持节点(Serving GPRS Support Node，SGSN)、PDN网关(PDN Gateway，P-GW)、服务网关(S-GW，Serving Gateway)、归属签约用户服务器(Home Subscriber Server，HSS)、服务器(Service)。 In order to facilitate the understanding of the present invention, a possible network architecture diagram applicable to the embodiment of the present invention is first introduced. As shown in FIG. 1 , it is an Evolved Packet System (EPS) network architecture diagram, including user equipment ( User Equipment (UE), Internet of Things (IoT) equipment, Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), Mobility Management Entity (MME), GPRS Service Support Node (SGSN), PDN Gateway (P-GW), Serving Gateway (S-GW, Serving Gateway), Home Subscriber Server (HSS), Server (Service) ).

其中，EUTRAN由多个演进型NodeB(eNodeB)组成的网络，实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能。eNodeB通过用户面接口S1-U和S-GW相连，用于传送用户数据；通过控制面接口S1-MME和MME相连，采用S1-AP协议实现无线接入承载控制等功能。SGSN通过Gb接口与GSM/EDGE无线接入网(GERAN)的基站控制器(Base Station Controller，BSC)连接，或通过Iu-PS接口与UMTS无线接入网(URAN)的无线网络控制器(Radio Network Controller，RNC)连接，进行移动数据的管理，如用户身份识别，加密，压缩等功能。MME主要负责用户即会话管理的所有控制平面功能，包括NAS信令及安全、跟踪区的管理、P-GW与S-GW的选择等。S-GW主要负责UE的数据传输、转发以及路由切换等，并作为UE在eNodeB之间切换时的本地移动性锚定点(对于每一个UE，每个时刻仅有一个S-GW为之服务)。P-GW作为公用数据网(Public Data Network，PDN)连接的锚定点，负责UE的IP地址分配，UE的数据报文过滤、速率控制、生成计费信息等。而IoT设备可以通过多种方式接入网络，IoT设备可通过直连链路(如无线接入技术)接入到网络，也可以先连接到一个中继节点(如UE)，然后再通过中继链路接入到网络。The EUTRAN is a network composed of multiple evolved NodeBs (eNodeBs), which implements wireless physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions. The eNodeB is connected to the S-GW through the user plane interface S1-U for transmitting user data. The S1-AP protocol is connected to the MME through the control plane interface, and the radio access bearer control function is implemented by using the S1-AP protocol. The SGSN is connected to the base station controller (BSC) of the GSM/EDGE radio access network (GERAN) through the Gb interface, or the radio network controller of the UMTS radio access network (URAN) via the Iu-PS interface (Radio) Network Controller (RNC) connects to manage mobile data, such as user identification, encryption, and compression. The MME is mainly responsible for all control plane functions of the user, that is, session management, including NAS signaling and security, tracking area management, P-GW and S-GW selection. The S-GW is mainly responsible for data transmission, forwarding, and routing handover of the UE, and serves as a local mobility anchor point when the UE switches between eNodeBs (for each UE, only one S-GW serves each time) . As the anchor point of the public data network (PDN) connection, the P-GW is responsible for IP address allocation of the UE, data packet filtering, rate control, and generation of charging information of the UE. The IoT device can access the network in multiple ways. The IoT device can access the network through a direct link (such as wireless access technology), or can be connected to a relay node (such as a UE) before passing through the medium. Follow the link to the network.

在图1所示的网络架构中，能够支持多终端共享号码功能，是指支持一个手机号码对应多张SIM或USIM，每张卡对应不同的IMSI标识，例如，一个用户的手机、智能手环、智能手表、智能眼镜可以配置不同的卡，而这些卡共用同一个手机号码，这样用户只需要对一个手机号码进行管理即可，方便了用户的使用。在多终端共享号码的场景中，假设终端A和终端B共享同一个手机号码，本发明实施例可以实现将终端A的业务切换至终端B，所切换的业务可以是语音业务、视频业务、分组数据业务等等，并且能够保证业务传输的连续性。例如，MME/SGSN接收第一终端发送的业务切换请求，所述业务切换请求用于请求切换源终端的待切换业务，所述业务切换请求携带所述源终端的标识；所述MME/SGSN根据所述业务切换请求，获取所述源终端的所述待切换业务的识别信息；所述MME/SGSN根据所述业务切换请求，确定所述待切换业务的目标终端；所述MME/SGSN为所述目标终端分配目标承载标识；所述MME/SGSN向所述SGW/PGW发送传输路径修改请求，所述传输路径修改请求携带所述待切换业务的识别信息、所述目标终端的标识和所述目标承载标识，所述传输路径修改请求用于请求所述SGW/PGW修改所述待切换业务的数据包的传输路径。相比现有技术，本发明实施例的方案能够实现多个终端之间的业务切换功能，并保证业务传输的连续性，进而提高终端的便捷性和智能性。In the network architecture shown in FIG. 1, the multi-terminal shared number function can be supported, which means that one mobile phone number is supported by multiple SIMs or USIMs, and each card corresponds to a different IMSI identifier, for example, a user's mobile phone and smart bracelet. Smart watches and smart glasses can be configured with different cards, and these cards share the same mobile phone number, so that the user only needs to manage one mobile phone number, which is convenient for the user. In the scenario where the multi-terminal shared number is used, it is assumed that the terminal A and the terminal B share the same mobile phone number. In this embodiment of the present invention, the service of the terminal A can be switched to the terminal B, and the switched service can be a voice service, a video service, or a packet. Data services, etc., and can guarantee the continuity of service transmission. For example, the MME/SGSN receives a service switching request sent by the first terminal, where the service switching request is used to request to switch the to-be-switched service of the source terminal, and the service switching request carries the identifier of the source terminal; the MME/SGSN is configured according to The service switching request acquires the identification information of the to-be-switched service of the source terminal; the MME/SGSN determines the target terminal of the to-be-switched service according to the service switching request; the MME/SGSN is The target terminal allocates a target bearer identifier; the MME/SGSN sends a transport path modification request to the SGW/PGW, where the transport path modification request carries the identification information of the to-be-switched service, the identifier of the target terminal, and the Target bearing And the transmission path modification request is used to request the SGW/PGW to modify a transmission path of the data packet of the to-be-switched service. Compared with the prior art, the solution of the embodiment of the present invention can implement the service switching function between multiple terminals, and ensure the continuity of service transmission, thereby improving the convenience and intelligence of the terminal.

And sending the downlink data packet of the modified destination IP address to the target terminal. This achieves switching the to-be-switched service of the source terminal to the target terminal.

可选地，步骤102具体可以采用如下四种可行的方案来实现：Optionally, step 102 can be implemented by using the following four feasible solutions:

在第一种可行的方案中，若所述业务切换请求未携带源承载标识和待切换业务的业务流模板，则所述第一核心网设备根据业务切换请求中携带的源终端的标识，获取所述源终端的IP地址，并将所述源终端的IP地址确定为所述待切换业务的识别信息。在这种情况下，所述第一核心网设备根据所述源终端的IP地址确定的待切换业务为源终端的全部业务。In a first feasible solution, if the service switching request does not carry the source bearer identifier and the service flow template of the to-be-switched service, the first core network device obtains the identifier of the source terminal carried in the service switching request. The IP address of the source terminal is determined, and the IP address of the source terminal is determined as the identification information of the service to be switched. In this case, the to-be-switched service determined by the first core network device according to the IP address of the source terminal is all services of the source terminal.

在第二种可行的方案中，若所述业务切换请求携带源承载标识，则所述第一核心网设备将所述源承载标识确定为所述待切换业务的识别信息。在这种情况下，所述第一核心网设备可以根据源终端的标识和所述源承载标识，将源终端中通过源承载标识所指示的承载传输的业务确定为待切换业务。In the second feasible solution, if the service switching request carries the source bearer identifier, the first core network device determines the source bearer identifier as the identification information of the to-be-switched service. In this case, the first core network device may determine, according to the identifier of the source terminal and the source bearer identifier, the service transmitted by the bearer indicated by the source bearer identifier in the source terminal as the service to be switched.

在第三种可行的方案中，若所述业务切换请求中携带所述待切换业务的业务流模板，则所述第一核心网设备将所述业务流模板确定为所述待切换业务的识别信息。In a third feasible solution, if the service switching request carries the service flow template of the to-be-switched service, the first core network device determines the service flow template as the identification of the to-be-switched service. information.

其中，一个业务对应一个TFT，一个TFT对应一个传输该业务的承载，一个TFT会包括多个包过滤器(packet filter，也称分组过滤器)，可以分为上行业务流模板与下行业务流模板，上行业务流模板是TFT中的上行包过滤器，下行业务流模板是TFT中的下行包过滤器。过滤器的主要内容是一个IP五元组，IP五元组包括：源IP地址、目的IP地址、源端口、目的端口和传输层协议号，其中，传输层协议可以分为传输控制协议(Transmission Control Protocol，TCP)、用户数据报协议(User Datagram Protocol，UDP)、序列分组交换协议(Sequenced Packet Exchange protocol，SPX)等。A service corresponds to a TFT, and a TFT corresponds to a bearer for transmitting the service. A TFT may include multiple packet filters (also referred to as packet filters), and may be classified into an uplink service flow template and a downlink service flow template. The uplink service flow template is an uplink packet filter in the TFT, and the downlink service flow template is a downlink packet filter in the TFT. The main content of the filter is an IP five yuan The IP quintuple includes: a source IP address, a destination IP address, a source port, a destination port, and a transport layer protocol number. The transport layer protocol can be classified into a Transmission Control Protocol (TCP) and a User Datagram Protocol. (User Datagram Protocol, UDP), Sequence Packet Exchange Protocol (SPX), and the like.

TFT在终端与PGW上使用，终端或PGW匹配业务数据包与TFT中包含的过滤器的过程就是检查业务数据包中的IP五元组与过滤器中的IP五元组是否匹配，若匹配，则将该业务数据包映射到与相匹配的TFT对应的承载上传输。因此，所述业务流模板能够唯一指示源终端中待切换业务。假设所述待切换业务是源终端与通信对端之间基于TCP协议的业务，则所述待切换业务的业务流模板中的过滤器包括的IP五元组包括：源终端的IP地址、通信对端的IP地址、源终端的端口、通信对端的端口和TCP协议号。The process of using the TFT on the terminal and the PGW, the terminal or the PGW matching the service data packet and the filter included in the TFT is to check whether the IP quintuple in the service data packet matches the IP quintuple in the filter, and if it matches, Then, the service data packet is mapped to the bearer corresponding to the matched TFT. Therefore, the service flow template can uniquely indicate the service to be switched in the source terminal. Assume that the to-be-switched service is a TCP-based service between the source terminal and the communication peer, and the IP quintuple included in the filter in the service flow template of the to-be-switched service includes: the IP address of the source terminal, and the communication IP address of the peer end, port of the source terminal, port of the communication peer, and TCP protocol number.

在第四种可行的方案中，若所述业务切换请求携带源承载标识和待切换业务的业务流模板，则所述第一核心网设备检测所述源承载标识对应的业务流模板与所述待切换业务的业务流模板是否相同；或者，所述第一核心网设备检测所述待切换业务的业务流模板对应的承载标识与所述源承载标识是否相同。In a fourth possible solution, if the service switching request carries the source bearer identifier and the service flow template of the service to be switched, the first core network device detects the service flow template corresponding to the source bearer identifier and the Whether the service flow template of the service to be switched is the same; or the first core network device detects whether the bearer identifier corresponding to the service flow template of the to-be-switched service is the same as the source bearer identifier.

若相同，则表示通过所述源承载标识所指示的承载传输的业务和所述业务流模板所指示的业务相同，因此，所述第一核心网设备将所述源承载标识和/或所述业务流模板确定为所述待切换业务的识别信息。If the same, the service indicated by the bearer transmission indicated by the source bearer identifier is the same as the service indicated by the service flow template, and therefore, the first core network device identifies the source bearer and/or the service The service flow template is determined as the identification information of the service to be switched.

若不相同，则表示通过所述源承载标识所指示的承载传输的业务和所述业务流模板所指示的业务不相同，因此，所述第一核心网设备将所述源承载标识和所述业务流模板确定为所述待切换业务的识别信息。If not, the service indicated by the source bearer identifier and the service indicated by the service flow template are different, and therefore, the first core network device identifies the source bearer and the The service flow template is determined as the identification information of the service to be switched.

可选地，步骤103具体可以采用如下两种可行的方案来实现：Optionally, step 103 can be implemented by using two feasible solutions:

Specifically, the first core network device authenticates the identifier of the target terminal, and if the target terminal and the source terminal correspond to the same user, the first core network device authorizes the identifier indication of the target terminal. Terminal And determining, by the target terminal, that the target terminal and the source terminal are different users, the first core network device does not switch the to-be-switched service.

在步骤103的第二种可行的方案中，若所述业务切换请求中未携带目标终端的标识，则所述第一核心网设备根据源终端的标识确定目标终端。In the second feasible solution of step 103, if the service switching request does not carry the identifier of the target terminal, the first core network device determines the target terminal according to the identifier of the source terminal.

209、所述第二核心网设备接收在所述目标承载上传输的上行数据包。209. The second core network device receives an uplink data packet transmitted on the target bearer.

其中，在待切换业务切换完成之后，所述第二核心网设备接收到的在所述目标承载上传输的上行数据包是由所述目标终端的发送的。The uplink data packet transmitted by the second core network device and transmitted on the target bearer is sent by the target terminal after the handover of the to-be-switched service is completed.

210、所述第二核心网设备将上行数据包中的源IP地址设置为所述源终端的IP地址。210. The second core network device sets a source IP address in the uplink data packet to an IP address of the source terminal.

举例来说，待切换业务为终端A和终端C之间的语音业务，将终端A的待切换业务切换至终端B之后，终端B发送的上行数据包携带的源IP地址为终端B的IP地址，目的IP地址为终端C的IP地址。第二核心网设备在接收到由终端B发送至终端C的上行数据包时，将上行数据包的源IP地址由终端B的IP地址修改为终端A的IP地址，这样终端C在接收到上行数据包时认为该数据包是由终端A发送的，以使终端C在所述待切换业务的上行数据包是由终端B发送的情况下也能够识别，即待切换业务从终端A到终端B的切换对终端C没有影响，从而保证了待切换业务传输的连续性。For example, the to-be-switched service is the voice service between the terminal A and the terminal C. After the to-be-switched service of the terminal A is switched to the terminal B, the source IP address carried by the uplink data packet sent by the terminal B is the IP address of the terminal B. The destination IP address is the IP address of terminal C. When receiving the uplink data packet sent by the terminal B to the terminal C, the second core network device modifies the source IP address of the uplink data packet from the IP address of the terminal B to the IP address of the terminal A, so that the terminal C receives the uplink. The data packet is considered to be sent by the terminal A, so that the terminal C can also identify that the uplink data packet of the to-be-switched service is sent by the terminal B, that is, the service to be switched is from the terminal A to the terminal B. The switching has no effect on the terminal C, thereby ensuring the continuity of the service transmission to be switched.

举例来说，同步骤210中的例子相同，终端C发送至终端B的下行数据包携带的源IP地址为终端C的IP地址，目的IP地址为终端A的IP地址。第二核心网设备接收到下行数据包时，将下行数据包的目的IP地址由终端A的IP地址修改为终端B的IP地址，从而能够将待切换业务的下行数据包传输到待切换业务切换后的终端B，保证了待切换业务数据包的正确传输。For example, as in the example in step 210, the source IP address carried by the downlink data packet sent by the terminal C to the terminal B is the IP address of the terminal C, and the destination IP address is the IP address of the terminal A. First When the second core network device receives the downlink data packet, the destination IP address of the downlink data packet is changed from the IP address of the terminal A to the IP address of the terminal B, so that the downlink data packet of the service to be switched can be transmitted to the service to be switched. Terminal B ensures the correct transmission of the service data packets to be switched.

其中，所述第二核心网设备接收到下行数据包时，获取下行数据包中的IP五元组信息，并根据下行数据包中的IP五元组信息匹配下行TFT，若检测到下行TFT是待切换业务的TFT，将所述下行数据包中的目的IP地址设置为所述目标终端的IP地址。The second core network device obtains the IP quintuple information in the downlink data packet when receiving the downlink data packet, and matches the downlink TFT according to the IP quintuple information in the downlink data packet, and if the downlink TFT is detected, The TFT of the service to be switched sets the destination IP address in the downlink data packet to the IP address of the target terminal.

在第一种情况中，若所述待切换业务的识别信息为所述源终端的IP地址，则待切换业务为所述源终端可支持的全部业务类型标识所指示的业务，进而所述待切换业务的TFT为所述源终端中全部业务的TFT。In the first case, if the identification information of the to-be-switched service is the IP address of the source terminal, the service to be switched is the service indicated by all the service type identifiers that the source terminal can support, and then the to-be-switched service The TFT of the switching service is a TFT of all services in the source terminal.

在第二种情况中，若所述待切换业务的识别信息为源承载标识，则待切换业务为所述源终端中通过所述源承载标识指示的承载进行传输数据包的业务，进而所述待切换业务的TFT为通过所述源承载标识指示的承载进行传输数据包的业务的TFT。In the second case, if the identification information of the to-be-switched service is the source bearer identifier, the to-be-switched service is a service for transmitting a data packet by using the bearer indicated by the source bearer identifier in the source terminal, and further The TFT of the service to be switched is a TFT that performs a service of transmitting a data packet by using a bearer indicated by the source bearer identifier.

在第三种情况中，若所述待切换业务的识别信息为所述待切换业务的业务流模板，则所述第二核心网设备可以直接确定待切换业务的TFT。In the third case, if the identification information of the to-be-switched service is the service flow template of the to-be-switched service, the second core network device may directly determine the TFT of the service to be switched.

在第四种情况中，若所述待切换业务的识别信息为源承载标识和所述待切换业务的业务流模板，则所述第二核心网设备检测到所述源承载标识对应的TFT为所述待切换业务的业务流模板，或者，所述第二核心网设备检测到所述待切换业务的业务流模板对应的承载标识为所述源承载标识，则所述第二核心网设备确定源承载标识和所述待切换业务的业务流模板所指示的业务相同，可以直接确定待切换业务的TFT；否则，所述第二核心网设备确定源承载标识和所述待切换业务的业务流模板所指示的业务不相同，并将源承载标识对应的TFT和所述传输路径修改请求中携带的业务流模板均确定待切换业务的TFT。In the fourth case, if the identification information of the to-be-switched service is the source bearer identifier and the service flow template of the to-be-switched service, the second core network device detects that the TFT corresponding to the source bearer identifier is The service flow template of the service to be switched, or the second core network device determines that the bearer identifier corresponding to the service flow template of the to-be-switched service is the source bearer identifier, and the second core network device determines The source bearer identifier is the same as the service indicated by the service flow template of the to-be-switched service, and may directly determine the TFT of the service to be switched; otherwise, the second core network device determines the source bearer identifier and the service flow of the to-be-switched service. The services indicated by the template are different, and the TFTs corresponding to the source bearer identifier and the service flow template carried in the transport path modification request are all determined by the TFTs to be switched.
