Description

用户注册信息的处理方法、装置及演进分组数据网关ePDG设备 技术领域
本公开涉及通信技术领域，例如涉及一种用户注册信息的处理方法、装置及演进分组数据网关ePDG设备。
背景技术
目前基于IP多媒体子系统(IP Multimedia Subsystem，IMS)架构的WiFi会话(Voice over WiFi，VoWiFi)业务，可通过在4G核心网络(Evolved Packet Core，EPC)中部署演进分组数据网关(Evolved Packet Data Gateway，ePDG)网元的方式实现。ePDG网元使得EPC网络具备无线局域网(Wireless Local Area Networks，WLAN)接入能力。
WLAN方式接入为一种非-第三代合作伙伴计划(non-3rd Generation Partnership Project，non-3GPP)的接入，假设终端处于“Untrusted Non-3GPP IP Access”，即WiFi无线网络。终端通过WiFi接入ePDG网元，从而附着到EPC网络，同时获取相关配置信息，如网络之间的互联协议(Internet Protocol，IP)地址、域名系统(Domain Name System，DNS)、代理呼叫会话控制功能(Proxy-Call Session Control Function，P-CSCF)地址等。然后借由与EPC网络建立的隧道传输会话初始协议(Session Initiation Protocol，SIP)消息，完成IMS网络的注册，最终以实现IMS语音以及其他IMS业务功能。
其中，终端与ePDG之间接口为SWu接口，建立基于IKEv2的安全加密连接。ePDG与公用数据网(Public Data Network，PDN)网关(PDN Gateway，PGW)之间为S2b接口，通过该接口建立通用分组无线服务(General Packet Radio Service，GPRS)隧道协议(GPRS Tunnelling Protocol，GTP)会话。PGW为终端分配EPC网络终端地址、DNS信息和P-CSCF地址，这些信息通过ePDG下发给终端。终端向会话边缘控制器(Session Border Controller，SBC)/P-CSCF发送SIP注册消息，消息的用户数据报协议(User Datagram Protocol，UDP)端口为知名端口5060。完成IMS的注册后，终端可进行VoWiFi等IMS业务。
在相关技术的VoWiFi注册过程中，PGW只向终端下发SBC/P-CSCF地址，并不包括端口号，因此终端在向IMS注册时一般使用的UDP端口为默认知名端口5060。
但相关的SBC产品通常具有可配SIP注册端口功能，可使用除默认知名端口 5060之外的其他端口注册。这样一方面可以使得在组网上更加灵活，另一方面，通过终端接入的端口号，SBC可以实现一些特有个性化产品功能，如根据端口号区分自身网元角色或者决策终端接入类型(接入类型可以为长期演进(Long Term Evolution，LTE)接入或WiFi接入)等多种个性化功能。
比如，针对终端接入类型的一个场景是，终端有可能由长期演进(Long Term Evolution，LTE)接入EPC网络，也可能由WiFi接入EPC网络。如果终端发送的SIP注册消息中未携带终端的接入类型信息，或携带的接入类型信息不准确，则IMS网络可能无法判断终端真实的接入类型。因为无论终端是通过LTE接入还是WiFi接入EPC网络，均可由锚定的PGW网元来为终端分配IP地址、下发SBC/P-CSCF地址。虽然PGW本身可以区分终端的接入类型，但PGW并无标准接口可直接将终端接入类型通知至SBC/P-CSCF网元。所以在这种情况下，IMS网络可能无法在收到终端SIP注册消息时，确定终端接入类型，例如，SBC网元可能无法使用通过区分不同端口号所带来的个性化产品功能。另外，如果通过在终端上手工配置端口号，对非专业的普通手机用户来说，配置的过程相对复杂和难以理解。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合可选实施例及附图进行详细描述。在不冲突的情况下，以下实施例和实施例中的特征可以相互组合。
本公开实施例提供了一种用户注册信息的处理方法、装置及ePDG设备，可以解决在VoWiFi注册过程中，终端无法灵活获取到SBC/P-CSCF开放的注册端口号的问题。
如图1所示，本公开实施例的用户注册信息的处理方法，包括步骤11-步骤13。
在步骤11中，演进分组数据网管ePDG获取待注册终端的IMS网络配置信息，该IMS网络配置信息包括为待注册终端分配的会话边界控制器/代理呼叫会 话控制功能SBC/P-CSCF地址。
在本公开的可选实施例中，上述IMS网络配置信息可包括为上述待注册终端分配的IP地址，IMS的SBC/P-CSCF地址等。
在步骤12中，ePDG在上述IMS网络配置信息中增加SBC/P-CSCF端口号信息，得到IMS注册消息。
可选地，ePDG首先获取为所述待注册终端配置的SBC/P-CSCF端口号信息，然后可通过在IMS网络配置信息的私有属性中携带所述SBC/P-CSCF端口号信息，得到IMS注册消息，其中，所述私有属性为RFC7296中定义的值大于16384的属性。其中，ePDG可以将SBC/P-CSCF的端口号信息配置在本地设备上，也可以从外部网元获取，如在建立GTP会话时从PGW获取上述SBC/P-CSCF端口号信息。
在步骤13中，ePDG将上述IMS注册消息发送给待注册终端，并指示所述待注册终端根据所述SBC/P-CSCF端口号信息和所述SBC/P-CSCF地址进行IMS注册。
在本公开的可选实施例中，终端接收到携带有SBC/P-CSCF端口号信息和所述SBC/P-CSCF地址的IMS注册信息后，向SBC/P-CSCF发送SIP注册消息，用户数据报协议(User Datagram Protocol，UDP)端口为ePDG下发的SBC/P-CSCF端口号，SBC/P-CSCF收到注册消息后进行后续处理，完成上述待注册终端的注册。
本公开实施例的上述技术方案，获取待注册终端的IMS网络配置信息，所述IMS网络配置信息包括为待注册终端分配的SBC/P-CSCF地址；在所述IMS网络配置信息中增加SBC/P-CSCF端口号信息，得到IMS注册消息；将所述IMS注册消息发送给所述待注册终端，并指示所述待注册终端根据所述SBC/P-CSCF端口号信息和所述SBC/P-CSCF地址进行IMS注册。
本公开实施例中通过在IMS网络配置信息中增加SBC/P-CSCF端口号信息，使得终端可以根据SBC/P-CSCF端口号信息和SBC/P-CSCF地址进行IMS注册，进而使SBC可以灵活配置端口，不需固定于某一端口，从而在组网上更加灵活。
可选地，上述步骤11可以包括：对所述待注册终端进行鉴权处理；
在所述待注册终端鉴权通过后，向PDN网关PGW发送建立GIP会话的会话请求消息；获取所述PGW根据所述会话请求消息返回的会话响应消息，所述会话响应响应消息携带有所述IMS网络配置信息。其中，可以通过3GPP AAA服务器对所述待注册终端进行鉴权处理。
本公开实施例的用户注册信息的处理方法，在VoWiFi场景下，终端使用EPC网络下发的SBC/P-CSCF的端口号进行IMS注册，同时可以无需要在终端上手工配置，进而使SBC能够灵活配置端口，不需固定于5060端口，从而在组网上更加灵活，SBC/P-CSCF网元也可启用端口的相关个性化功能。
如图2所示，本公开实施例的用户注册信息的处理方法，包括步骤21-步骤29。
在步骤21中，终端UE与eDPG建立IKE隧道。
在步骤22中，终端通过ePDG与3GPP AAA服务器之间进行鉴权，网络侧进行鉴权和授权处理。
在步骤23中，ePDG向PGW发送建立会话请求的消息，请求建立GTP会话。
在步骤24中，PGW进行IP连接访问网络IP-CAN会话处理，包括终端IP地址的分配、与策略与计费规则功能(Policy and Charging Rules Function，PCRF)交互的处理等。
在步骤25中，PGW通知3GPP AAA服务器更新PGW地址信息。
在步骤26中，PGW向ePDG返回会话建立响应消息，其中包含分配给终端的IP地址，IMS的SBC/P-CSCF地址。
在步骤27中，终端与ePDG建立Internet协议安全性(Internet Protocol Security，IPSec)隧道。
在步骤28中，ePDG给终端返回IKEv2响应消息，携带PGW下发的终端的IP地址，IMS的SBC/P-CSCF地址等信息，同时在配置属性CFG_REPLY中通过私有属性类型携带SBC/P-CSCF端口号。
在步骤29中，终端向SBC/P-CSCF发送SIP注册消息，UDP端口为ePDG下发的SBC/P-CSCF端口号。其中，消息通过IPsec隧道、GTP隧道转发到IMS网络，SBC/P-CSCF收到注册消息后进行后续处理。
本公开实施例的用户注册信息的处理方法，在IMS网络配置信息中增加SBC/P-CSCF端口号信息，使得终端可以根据SBC/P-CSCF端口号信息和SBC/P-CSCF地址进行IMS注册，进而使SBC可以灵活配置端口，不需固定于某一端口，从而在组网上更加灵活。
