Definitions
- the present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for network access. Background technique
- the mobile communication network includes GSM, UMTS and LTE, and each network uses a proprietary access network.
- the GSM access network is GERAN
- the UMTS access network is UTRAN
- the LTE access network is E-UTRAN.
- GERAN and UTRAN can be implemented using the same network device.
- network functions are divided according to network speed, for example, GSM and UMTS networks are used for voice services (such as calling, etc.), and LTE networks are used for data services (such as Internet access).
- the network side uses the CSFB technology to cause the UE to fall back to the GSM/UMTS circuit domain (CS), and the UE sub-CS performs voice service.

- the upper layer service does not support IMS voice.
- the UE accesses the network the UE mode configuration reported by the UE to the network side is voice priority "Voice Centric" and circuit domain voice priority, and IMS data domain voice is followed by "CS voice preferred, IMS PS Voice as secondary".
- the UE When the UE performs the voice service from the LTE access, if the network side supports the VoLTE technology but does not deploy the CSFB, the information that the network responds to the terminal is "CS domain registration failure", and prompts the terminal network side to support the VoLTE technology. After receiving the response, the UE does not reselect the GERAN/UTRAN network because the underlying chip of the UE supports IMS voice, so that the UE will continue to camp in the LTE network (E-UTRAN) in preparation for implementing the VoLTE technology.
- E-UTRAN LTE network

Or, because the UE cannot implement the VoLTE technology, the voice bearer channel for performing voice service data transmission cannot be established in the LTE network, and the UE voice service is unavailable. In the present invention, it can be judged by the network side whether the UE needs to perform the network switching.

Description
网络接入的方法及装置 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种网络接入的方法及装置。 背景技术
目前,移动通信网络包括 GSM、 UMTS和 LTE,每个网络使用专有的接入网, 例如 GSM的接入网为 GERAN、UMTS的接入网为 UTRAN、LTE的接入网为 E-UTRAN, 其中 GERAN和 UTRAN可使用同一套网络设备进行实现。 为了提高网络使用效 率, 根据网络速度对网络功能进行划分, 例如使用 GSM和 UMTS网络进行语音 业务(如打电话等), 使用 LTE网络进行数据业务(如上网等)。 如果 UE在进 行数据业务后欲进行语音业务,则网络侧通过 CSFB技术使 UE回落到 GSM/UMTS 的电路域 ( c i rcu i t sec t ion , 简称 CS ) 中, UE子 CS 中进行语音业务。 若 网络侧或 UE无法提供 CSFB技术, 则考虑在 LTE网络中实现语音业务, 又称 VoLTE技术或 IMS语音方案。 在 VoLTE技术中, 使用 IMS网络和 LTE网络, 其 中 IMS 网络用于实现通话建立、 号码分析、 通话拆线等信令处理功能, 而语 音数据承载则在 LTE网络用于实现语音数据承载和传输。 具体流程如下所示: 第一步、 UE建立串联 LTE和 IMS的 IMS PDN连接, 通过建立的 IMS PDN 在 IMS网络中进行注册, 以便 IMS网络实现通话建立、 号码分析、 通话拆线 等信令处理。
第二步、 UE通过建立的 IMS PDN在 LTE中完成语音承载建立过程中需要 进行的信令交互, 并 LTE中建立语音承载通道。
第三步、 当语音承载通道建立成功后, 在 LTE 网络中使用已建立的语音 承载进行语音数据传输, 实现语音业务。
在实现上述网络接入的过程中, 发明人发现现有技术中至少存在如下问 题:
现有的移动终端中, 存在底层芯片支持 IMS语言但上层业务(如终端中
的软件 ) 不支持 IMS语言的情况。 例如 UE (如苹果手机 iPhone 5 )底层芯片 支持 IMS语音, 上层业务不支持 IMS语音。 当 UE接入到网络时, UE上报给网 络侧的 UE模式配置是语音优先 "Voice Cent r ic "和电路域语音优先, IMS数 据域语音其次 "CS voice preferred, IMS PS Voice as secondary " 。 当 UE 从 LTE接入进行语音业务时, 如果网络侧已支持 VoLTE技术但未部署 CSFB, 则网络响应到终端的信息为 "CS域注册失败", 并提示终端网络侧支持 VoLTE 技术。 UE收到该响应后, 由于 UE的底层芯片支持 IMS语音, 因此其不会重选 GERAN/UTRAN网络,使得 UE将继续驻留在 LTE网络(E-UTRAN)中准备实施 VoLTE 技术。 但是由于 UE 的上层业务不支持 IMS语言, 而底层芯片无法独立实施 VoLTE技术, 因此 UE无法实施 VoLTE, 即 UE无法在 LTE网络中建立用于进行 语音业务数据传输的语音承载通道, 导致 UE语音业务不可用。 发明内容

本发明实施例提供了一种网络接入的方法, 如图 6 所示, 所述方法应用 于网络服务器中, 所述网络服务器如移动性管理实体(Mobi l i ty Management Ent i ty, 简称 MME ), 所述方法在上述装置中进行执行, 所述方法包括:
步骤 601、 当电路域注册失败时, 根据用户设备 UE的 IMS功能支持状态 确定待转网用户设备。
所述电路域为 GSM/UMTS网络中的电路域, 该电路域用于为用户设备提供 语音业务。 所述 IMS功能支持状态用于表示所述用户设备是否支持 IMS语言。 如果所述用户设备支持 IMS语言, 则能够通过 IMS网络在 LTE网络中建立语 音业务通话承载, 进而实现在 LTE网络中进行语音通话。
步骤 602、 根据所述待转网用户设备的通信配置参数确定目标用户设备。 所述通信配置参数用于表示所述待转网设备的优先业务类型。 在 3GPP协 议中用户设备的优先业务类型分为 "语音优先(Voice cent r ic ) "和 "数据 优先 (Data centr ic ) " 两种类型。 "语音优先 ( Voice cent r ic ) "主要以 语音业务为主, 同时也可以进行上网等数据业务, 通常以语音优先为优先业 务类型的设备为手机。 对于语音优先的用户设备的业务定义为, 确保语音业 务始终可用。 如果是由于 UE自身原因或者网络原因, 导致不能在 LTE网络中
获取到 CSFB语音功能或者不能获取 IMS语音功能,则重选 GERAN/UTRAN接入; 重选后直接在 GERAN/UTRAN网络的 CS域获取语音业务。 对于数据优先的用户 设备, 如果语音业务不能获取, 则继续驻留在 LTE 网络, 以确保数据业务始 终可用。
步骤 603、 向所述目标用户设备发送携带有预设原因值的转网指令, 所述 转网指令用于指示所述目标用户设备接入到语音业务接入网络。
预设原因值为重选 GERAN/UTRAN 指令 ( Rese lec t GERAN/UTRAN Ind i ca t ion )。 现有的协议中已规定, 当 UE接收到重选 GERAN/UTRAN指令时, UE断开与当前网络的连接, 并重新建立与 GERAN/UTRAN网络的连接。

步骤 601b、 当电路域注册失败时, 如果用户设备不支持 IMS功能, 确定 所述用户设备为待转网用户设备。
判断用户设备是否为待转网用户设备所使用的参数如表 1所示。
当用户设备支持 IMS功能且在预设时长内未建立 IMS承载, 或者用户设 备不支持 IMS功能, 则将所述用户设备确定为待转网用户设备。
本发明实施例提供的网络接入的方法, 能够根据用户设备的 IMS 功能支 持情况和 IMS承载建立情况确定待转网用户设备, 进而保证服务器能够确定 需要转往的用户设备。
本发明实施例还提供了一种网络接入的方法, 作为对图 6 所示方法的具 体说明, 如图 8所示, 步骤 602、 根据待转网用户设备的通信配置参数确定目 标用户设备, 具体可通过下述方式进行实施:
步骤 801、 获取所述待转网用户设备的通信配置参数。
通信配置参数用于表示用户设备的优选业务类型,如语音业务优先 Vo ice Cent r ic或数据业务优先 Da ta Cent r ic。
步骤 802、 如果通信配置参数为语音业务优先 Voice Cent r ic , 将所述待 转网用户设备确定为目标设备。
当待转网用户设备的配置参数为语音业务优先时, 需要保证所述待转网 用户设备的语音业务保持畅通, 进而将该待转网用户设备确定为目标设备。
若所述待转网用户设备的配置参数为数据优先, 则需要保证所述待转网 用户设备的数据业务(如移动网络数据传输业务)保持畅通, 无需将所述待 转网用户设备确定为目标设备。
