一种建立承载的方法及装置Method and device for establishing bearer技术领域Technical field

本文涉及但不限于通信领域，具体涉及一种建立承载的方法及装置。This document relates to, but is not limited to, the field of communications, and specifically relates to a method and apparatus for establishing a bearer.

背景技术Background technique

在长期演进(LTE，Long Term Evolution)系统中，终端如要使用数据业务必须先与网络建立分组数据网络(Packet Data Network，PDN)连接演进分组域系统(Evolved Packet System，EPS)承载。使用不同的数据业务时终端需要与不同的PDN之间建立EPS承载，也就是使用不同的接入点名称(APN，Access Point Name)与网络建立EPS承载。In the Long Term Evolution (LTE) system, if a terminal needs to use data services, it must first establish a Packet Data Network (PDN) with the network to connect to an Evolved Packet System (EPS) bearer. When different data services are used, the terminal needs to establish an EPS bearer with different PDNs, that is, use different access point names (APNs) to establish EPS bearers with the network.

目前，终端与网络之间建立PDN连接的方法包括，每次对一个PDN网络单独建立一个EPS承载。比如中国移动支持VoLTE的终端，开机后会先建立APN“cmnet”的EPS承载，然后再建立APN“ims”的EPS承载。Currently, a method for establishing a PDN connection between a terminal and a network includes separately establishing an EPS bearer for each PDN network. For example, China Mobile supports VoLTE terminals. After booting, it will first establish an APN "cmnet" EPS bearer, and then establish an APN "ims" EPS bearer.

本发明的实施方式Embodiments of the invention

下文中将结合附图对本发明的实施例进行详细说明。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

中国移动支持VoLTE的终端，开机后会先建立APN“cmnet”的EPS承载，然后再建立APN“ims”的EPS承载，这是两个独立的过程，需要使用两次PDN连接建立信令流程。而建立PDN连接的方法是每次对一个PDN单独建立一个EPS承载。如果要建立两个PDN连接EPS承载就需要使用两次PDN连接建立信令流程。如果终端开机后需要进行更多的业务就需要建立更多的PDN连接EPS承载，也就需要分别执行多次PDN连接建立流程。这不仅会增加终端与网络之间的交互及信令开销，而且PDN连接EPS承载的建立速度慢，导致无法及时获取到可用业务。如图1A、1B、1C所示，当终端要和网络建立三个不同APN的PDN连接时，必须按顺序完成APN1、APN2、APN3三个不同的PDN连接建立流程。相应的，如图1D所示，需要释放PDN连接时也需分别执行相应的释放流程。China Mobile supports VoLTE terminals. After booting, it will establish the APN "cmnet" EPS bearer and then establish the APN "ims" EPS bearer. This is a two-independent process. It is necessary to use two PDN connections to establish a signaling flow. The method of establishing a PDN connection is to establish an EPS bearer separately for one PDN at a time. If two PDN connection EPS bearers are to be established, it is necessary to use two PDN connections to establish a signaling flow. If more services need to be established after the terminal is powered on, more PDN connection EPS bearers need to be established, and multiple PDN connection establishment processes need to be performed separately. This not only increases the interaction between the terminal and the network, but also the signaling overhead. The establishment of the PDN connection EPS bearer is slow, and the available services cannot be obtained in time. As shown in FIG. 1A, FIG. 1B and FIG. 1C, when the terminal establishes a PDN connection of three different APNs with the network, three different PDN connection establishment procedures of APN1, APN2, and APN3 must be completed in order. Correspondingly, as shown in FIG. 1D, when the PDN connection needs to be released, the corresponding release process needs to be performed separately.

本申请建立PDN连接EPS承载的方案，使用一次信令流程可同时建立多条不同APN的PDN连接，避免了多个PDN连接需要分别执行多次PDN连接建立信令流程，可以有效减少终端与网络之间的交互及信令开销，加速PDN连接EPS承载建立的速度，使用户更快速地获取到可用业务。The present invention establishes a PDN connection EPS bearer solution, and can establish multiple PDN connections of different APNs at the same time by using one signaling process, which avoids multiple PDN connections and needs to perform multiple PDN connection establishment signaling processes separately, which can effectively reduce terminals and networks. The interaction between the EPS and the signaling overhead speeds up the establishment of the PDN connection EPS bearer, enabling the user to obtain the available services more quickly.

本发明实施例提供了一种建立承载的方法，如图2所示，包括：An embodiment of the present invention provides a method for establishing a bearer, as shown in FIG. 2, including:

步骤201，对至少两个APN对应的PDN同时向网络侧发起请求；Step 201: Initiate a request to the network side of the PDN corresponding to the at least two APNs at the same time;

步骤203，激活所述至少两个APN对应的EPS承载。Step 203: Activate an EPS bearer corresponding to the at least two APNs.

本实施例可同时发起至少两个不同APN的PDN连接并同时激活相应的至少两个EPS承载，从而可使用一次信令流程同时建立至少两条不同APN的PDN连接，有效减少终端与网络之间的交互及信令开销，提高PDN连接EPS承载建立的效率。In this embodiment, the PDN connection of the at least two different APNs can be simultaneously initiated and the corresponding at least two EPS bearers can be activated at the same time, so that the PDN connection of at least two different APNs can be simultaneously established by using one signaling process, thereby effectively reducing the terminal and the network.

For example, when the terminal does not agree to activate, the ACTIVATE DEFAULT EPS BEARER CONTEXT REJECT signaling may be sent to the network side to reject an EPS bearer. Activation, in which the cell "EPS bearer identity" carried in this signaling specifies the specific EPS bearer that is rejected for activation.

本实施例中，所述激活所述至少两个APN对应的EPS承载之后，如果网络侧需要释放一个或多个APN的PDN连接EPS承载或者终端向网络侧请求过释放一个或多个APN的PDN连接EPS承载，那么上述方法还可以包括：接收来自网络侧的释放EPS承载请求，所述释放EPS承载请求携带所述至少两个APN中一个或多个APN对应的EPS承载参数；根据所述释放EPS承载请求，去激活相应APN的PDN连接EPS承载。如此，终端可以根据网络侧的指示将一个或多个APN的PDN连接EPS承载进行释放。In this embodiment, after the activation of the EPS bearer corresponding to the at least two APNs, if the network side needs to release the PDN connection EPS bearer of one or more APNs, or the terminal requests the network side to release the PDN of one or more APNs.

Improve the efficiency of PDN connection EPS bearer establishment.

下面以具体实例对本申请进行详细说明。The present application will be described in detail below by way of specific examples.

中国移动网络下的终端在使用internet数据业务时需要使用APN“cmnet”建立EPS承载，在使用彩信业务时需要使用APN“mms”建立EPS承载，而在使用VoLTE业务时需要使用APN“ims”建立EPS承载。一些业务要求实现“一直在线”功能，也就是终端开机后就立即建立PDN连接EPS承载，比如目前中国移动支持VoLTE的终端开机后就要建立APN“cmnet”和APN“ims”的EPS承载。后续随着业务的增加，要求“一直在线”功能的业务可能越来越多，也就是开机后要求立即建立的PDN连接EPS承载也会越来越多，比如APN“rcs”、APN“xcap”等的EPS承载都有可能在开机后立即建立。中国移动支持VoLTE的终端开机后会先建立APN“cmnet”的EPS承载，然后再建立APN“ims”的EPS承载，这是两个独立的过程，需要使用两次PDN连接建立信令流程。如果终端开机后需要进行更多的业务就需要建立更多的PDN连接EPS承载，也就需要多次执行PDN连接建立信令流程。When using the internet data service, the terminal in the China Mobile network needs to use the APN "cmnet" to establish the EPS bearer. When using the MMS service, you need to use the APN "mms" to establish the EPS bearer. When using the VoLTE service, you need to use the APN "ims" to establish the EPS bearer. EPS bearer. Some services require the "always on" function, that is, the PDN connection EPS bearer is established immediately after the terminal is powered on. For example, the mobile terminal supporting the VoLTE terminal of China Mobile must establish the EPS bearer of APN "cmnet" and APN "ims". With the increase of services, the services that require the "always on" function may be more and more, that is, the PDN connection EPS bearers that are required to be established immediately after booting will be more and more, such as APN "rcs" and APN "xcap". Equivalent EPS bearers are likely to be established immediately after booting. After the China Mobile supports VoLTE, the APN "cmnet" EPS bearer will be established first, and then the APN "ims" EPS bearer will be established. This is a two-independent process. It is necessary to use two PDN connections to establish a signaling flow. If more services need to be established after the terminal is powered on, more PDN connection EPS bearers need to be established, and the PDN connection establishment signaling process needs to be performed multiple times.

通过本申请可以将多个PDN连接建立过程放到一个信令流程当中，在需要“一直在线”功能的业务越来越多的情况下减少终端与网络之间的交互及信令开销，加速业务PDN连接EPS承载建立速度，使用户更快速地获取到可用业务。Through this application, multiple PDN connection establishment processes can be put into one signaling process, and interaction and signaling overhead between the terminal and the network are reduced, and services are accelerated, in the case where more and more services are required to be "always on". The PDN connects to the EPS bearer establishment speed, enabling users to obtain available services more quickly.
