背景技术Background technique
随着互联网应用的迅速发展，越来越多的装置需要IP地址以与互联网进行通信，例如个人电脑、智能终端、笔记本电脑、智能手机以及各种电子装置。上述情况将导致互联网协议第四版(Internet Protocol Version 4,IPv4)提供的普遍采用的IP地址用尽的问题。为了满足快速发展的IP地址需求，互联网工程任务组(Internet Engineering TaskForce,IETF)已经提出了IPv6以解决IPv4地址未来耗尽的问题，并且提供足够的地址空间、简化的报头格式(header format)，支持认证和加密(authentication and privacy)、地址分配的自动配置以及新的服务质量(Quality-of-Service,QoS)功能。IPv4使用32个比特作为IP地址并且因此具有232个可能地址，而IPv6使用128个比特作为IP地址并且因此具有2128个可能地址(大约340乘以10的36次方个或3.4×1038个)。上述扩展能够满足互联网上更多装置与用户并且提供分配地址的较大灵活性以及路由业务的效率。这也缓解了网络地址转换(Network Address Translation,NAT)的需求，因此IPv6为广泛部署的用于解决IPv4地址耗尽问题的工作。典型地，IPv6由两部分组成：用于路由的64比特网络前缀(为了简化这里称为前缀)，以及用于鉴定主机网络接口的64比特接口标识(interface identifier)。通常，上述前缀包含在IPv6地址的最高有效64位比特中。使用改进的扩展唯一标识符64(Extended Unique Identifier-64,EUI-64)格式从接口的介质访问控制层(Media AccessControl,MAC)地址生成接口标识，上述由全球移动通信系统增强型数据速率GSM演进无线接入网络/通用陆地无线接入网络(GSM EDGE Radio Access Network/UniversalTerrestrial Radio Access Network,GERAN/UTRAN)网关通用分组无线业务支持节点(Gateway GPRS Support Node,GGSN)分配，由演进UTRAN(Evolved UTRAN,E-UTRAN)公共数据网网关(PDN Gateway,PGW)分配，随机建立或者手动分配。特别地，使用无状态地址自动配置(stateless address auto-configuration,SLAAC)配置动态IPv6地址。With the rapid development of Internet applications, more and more devices need IP addresses to communicate with the Internet, such as personal computers, smart terminals, notebook computers, smart phones and various electronic devices. The above situation will lead to the exhaustion of commonly used IP addresses provided by the Internet Protocol Version 4 (Internet Protocol Version 4, IPv4). In order to meet the rapid development of IP address requirements, the Internet Engineering Task Force (IETF) has proposed IPv6 to solve the problem of future exhaustion of IPv4 addresses, and to provide sufficient address space and a simplified header format. Support authentication and encryption (authentication and privacy), automatic configuration of address assignment, and new Quality-of-Service (QoS) functions. IPv4 uses 32 bits for an IP address and therefore has 232 possible addresses, while IPv6 uses 128 bits for an IP address and thus has 2128 possible addresses (about 340 times 1036 or 3.4×1038 indivual). The above expansion can satisfy more devices and users on the Internet and provide greater flexibility in address allocation and efficiency in routing services. This also alleviates the requirement of Network Address Translation (NAT), so IPv6 is widely deployed to solve the problem of IPv4 address exhaustion. Typically, IPv6 consists of two parts: a 64-bit network prefix (here referred to as a prefix for simplicity) used for routing, and a 64-bit interface identifier (interface identifier) used to identify a host network interface. Typically, the above prefixes are included in the most significant 64 bits of an IPv6 address. Use the improved Extended Unique Identifier-64 (Extended Unique Identifier-64, EUI-64) format to generate the interface identifier from the interface's Media Access Control layer (Media Access Control, MAC) address, the above-mentioned enhanced data rate GSM evolution by the Global System for Mobile Communications Radio Access Network/Universal Terrestrial Radio Access Network (GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network, GERAN/UTRAN) Gateway General Packet Radio Service Support Node (Gateway GPRS Support Node, GGSN) distribution, by Evolved UTRAN (Evolved UTRAN , E-UTRAN) public data network gateway (PDN Gateway, PGW) allocation, random establishment or manual allocation. In particular, the dynamic IPv6 address is configured using stateless address auto-configuration (SLAAC).
然而，因为未设定路由器通告(Router Advertisement,RA)的O旗标(O-flag)或者不存在适当协议以从移动终端(Mobile Terminal,MT)取得IPv6 DNS及/或SIP服务器地址，所以终端设备(Terminal Equipment,TE)可取得IPv6地址但不能获得IPv6 DNS及/或SIP服务器地址。因此，TE不能及时取得所需IPv6 DNS服务器地址用于分析域名及/或不能取得IPv6SIP服务器地址用于启动互联网协议电话(Voice over Internet Protocol,VoIP)或IP多媒体子系统(IP Multimedia Subsystem,IMS)服务的会话注册(sessionregistration)。However, because the O flag (O-flag) of the Router Advertisement (RA) is not set or there is no appropriate protocol to obtain the IPv6 DNS and/or SIP server address from the mobile terminal (Mobile Terminal, MT), the terminal A device (Terminal Equipment, TE) can obtain an IPv6 address but cannot obtain an IPv6 DNS and/or SIP server address. Therefore, TE cannot obtain the required IPv6 DNS server address in time for domain name analysis and/or cannot obtain the IPv6 SIP server address for starting Voice over Internet Protocol (VoIP) or IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) Service session registration (sessionregistration).

图2是根据本发明第一实施例描述的移动通信系统中获取IPv6 DNS及/或SIP服务器地址的消息时序图。如图2所示，在步骤S210中，MT 120与服务网络130通过激活分组数据协议上下文请求/激活分组数据协议上下文接收消息(Activate PDP Context Request/Activate PDP Context Accept message)启动分组数据协议上下文激活进程(PDPContext Activation Procedure)。具体地，激活分组数据协议上下文请求/激活分组数据协议上下文接收消息可包含多个参数，例如关于已请求接入点名称(Access Point Name,APN)、PDP类型、协议配置选项(Protocol Configuration Option,PCO)等信息，上述每个信息皆包含在激活分组数据协议上下文请求/激活分组数据协议上下文接收消息的相应信息元(Information Element,IE)中。APN是涉及用户希望连接的外部分组数据网络或服务的逻辑名，并且TE 110或MT 120可使用APN来选择对于特定外部网络的参考点或选择服务。将PDP类型设定为表示“IPv6”或“IPv4v6”的数值。PCO可包含协商认证协议数据(negotiatedAuthentication Protocol data)。PCO可包含协商网络控制协议数据(negotiatedNetwork Control Protocol data)。值得注意的是，因为激活PDP上下文的步骤是现有技术中的普遍技术，所以本发明未提供图2中激活PDP上下文步骤的细节描述。在本实施例中，在步骤S210，MT 120与服务网络130也可启动缺省演进分组系统(Evolved Packet System,EPS)承载上下文激活进程(Bearer Context Activation Procedure)、UE请求分组数据网络(Packet Data Network)连接进程(Connectivity Procedure)或EPS服务的长期演进附着(LTE Attach)进程。通过ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST消息启动缺省EPS承载上下文激活进程用于接收PCO信息，其中ACTIVATE DEFAULT EPS BEARERCONTEXT REQUEST消息可包含下列信息元(IE)：协议鉴别符(Protocol Discriminator)、EPS承载标识、进程交易标识(Procedure transaction identity)、激活缺省EPS承载上下文请求消息标识、EPS QoS、APN与公共数据网(PDN)地址。当激活了PDP上下文激活进程、缺省EPS承载上下文激活进程、UE请求PDN连接进程或EPS服务的长期演进附着进程时，在步骤S220中，MT 120可从PCO得到IPv6 DNS及/或代理呼叫会话控制功能(Proxy-Call SessionControl Function,P-CSCF)服务器地址。值得注意的是，P-CSCF服务器是一种IMS终端的第一接触点的SIP服务器。上述P-CSCF服务器可位于受访网络或本地网络中。在注册期间将P-CSCF分配至IMS终端，并且在注册期间不进行改变。P-CSCF位于所有信令消息(signalingmessage)的路径上，并且可检查每一个消息。其进一步认证用户并且与IMS终端建立安全连接。当前3GPP标准中指定的P-CSCF发现(discovery)包含在会话管理进程期间请求PCO中的P-CSCF地址供应。在本实施例中，某些IPv6 DNS及/或SIP服务器地址可预存在MT 120的非易失性存储器中，因此MT 120也可从非易失性存储器得到IPv6 DNS及/或SIP服务器地址。当在步骤S230来自服务网络130的路由器通告的O旗标设定为0时，则在步骤S240中MT 120可将路由器通告的O旗标设定为1并且将路由器通告(O旗标等于1)发送至TE 110。具体地，设定为1的路由器通告的O旗标表示服务网络130具有互联网协议第六版动态主机分配协议(DHCPv6)服务器并且设定为0的路由器通告的O旗标表示服务网络130不具有DHCPv6服务器。当TE 110接收路由器通告(O旗标等于1)时，在步骤S250，TE 110可向MT 120发送互联网协议第六版动态主机分配协议信息请求(DHCPv6 INFORMATION-REQUEST)消息。值得注意的是，如果将路由器通告的O旗标设定为0，则TE 110不向MT 120发送DHCPv6 INFORMATION-REQUEST消息。当MT 120从TE 110接收DHCPv6 INFORMATION-REQUEST消息时，在步骤S260，MT 120可根据PCO中的IPv6 DNS及/或P-CSCF服务器地址及/或非易失性存储器中的IPv6DNS及/或SIP服务器地址向TE 110发送互联网协议第六版动态主机分配协议回复(DHCPv6REPLY)消息。具体地，如果来自PCO的IPv6 DNS及/或P-CSCF服务器地址对于用户来说是需要的和足够的，则MT 120仅根据PCO中的IPv6 DNS及/或P-CSCF服务器地址向TE 110发送DHCPv6 REPLY消息。然而，如果来自PCO的IPv6 DNS及/或P-CSCF服务器地址对于用户来说不是需要的和足够的，则MT 120进一步根据非易失性存储器中的IPv6 DNS及/或SIP服务器地址向TE 110发送DHCPv6 REPLY消息。Fig. 2 is a sequence diagram of messages for obtaining IPv6 DNS and/or SIP server addresses in the mobile communication system described according to the first embodiment of the present invention. As shown in FIG. 2 , in step S210, the MT 120 and the service network 130 initiate packet data protocol context activation through an activation packet data protocol context request/activation packet data protocol context receive message (Activate PDP Context Request/Activate PDP Context Accept message) Process (PDPContext Activation Procedure). Specifically, the Activation Packet Data Protocol Context Request/Activation Packet Data Protocol Context Receive message may contain multiple parameters, such as about the requested Access Point Name (Access Point Name, APN), PDP type, protocol configuration option (Protocol Configuration Option, PCO) and other information, each of the above information is included in the corresponding information element (Information Element, IE) of the packet data protocol context activation request/activation packet data protocol context reception message. APN is a logical name referring to an external packet data network or service that a user wishes to connect to, and the TE 110 or MT 120 can use the APN to select a reference point for a specific external network or to select a service. Set the PDP type to a value indicating "IPv6" or "IPv4v6". The PCO may include negotiated Authentication Protocol data. The PCO may include negotiated Network Control Protocol data. It should be noted that because the step of activating the PDP context is a common technique in the prior art, the present invention does not provide a detailed description of the step of activating the PDP context in FIG. 2 . In this embodiment, in step S210, the MT 120 and the service network 130 may also start the default Evolved Packet System (Evolved Packet System, EPS) bearer context activation procedure (Bearer Context Activation Procedure), UE request packet data network (Packet Data Network) connection procedure (Connectivity Procedure) or EPS service long-term evolution attach (LTE Attach) procedure. The default EPS bearer context activation process is started through the ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message to receive PCO information. The ACTIVATE DEFAULT EPS BEARERCONTEXT REQUEST message may contain the following information elements (IE): protocol discriminator (Protocol Discriminator), EPS bearer identifier, Procedure transaction identity, activation default EPS bearer context request message identity, EPS QoS, APN and public data network (PDN) address. When the PDP context activation process, default EPS bearer context activation process, UE request PDN connection process or EPS service long-term evolution attach process is activated, in step S220, MT 120 can obtain IPv6 DNS and/or proxy call session from PCO Control function (Proxy-Call SessionControl Function, P-CSCF) server address. It should be noted that the P-CSCF server is a SIP server of the first contact point of the IMS terminal. The above-mentioned P-CSCF server may be located in the visited network or the local network. The P-CSCF is assigned to the IMS terminal during registration and is not changed during registration. The P-CSCF is on the path of all signaling messages and can inspect each message. It further authenticates the user and establishes a secure connection with the IMS terminal. P-CSCF discovery as specified in current 3GPP standards involves requesting P-CSCF address provisioning in the PCO during the session management procedure. In this embodiment, some IPv6 DNS and/or SIP server addresses can be pre-stored in the non-volatile memory of MT 120, so MT 120 can also obtain IPv6 DNS and/or SIP server addresses from the non-volatile memory. When the O flag of the router advertisement from the service network 130 is set to 0 in step S230, then in step S240 the MT 120 may set the O flag of the router advertisement to 1 and set the router advertisement (O flag equal to 1 ) to TE 110. Specifically, a router advertisement O flag set to 1 indicates that the service network 130 has an Internet Protocol version 6 Dynamic Host Assignment Protocol (DHCPv6) server and a router advertisement O flag set to 0 indicates that the service network 130 does not have DHCPv6 server. When the TE 110 receives the router advertisement (the O flag is equal to 1), the TE 110 may send an Internet Protocol version 6 Dynamic Host Assignment Protocol Information Request (DHCPv6 INFORMATION-REQUEST) message to the MT 120 at step S250. It is worth noting that TE 110 does not send a DHCPv6 INFORMATION-REQUEST message to MT 120 if the O flag of the router advertisement is set to 0. When the MT 120 receives the DHCPv6 INFORMATION-REQUEST message from the TE 110, in step S260, the MT 120 may, according to the IPv6 DNS and/or P-CSCF server address in the PCO and/or the IPv6 DNS and/or SIP address in the non-volatile memory The server address sends an Internet Protocol version 6 Dynamic Host Assignment Protocol reply (DHCPv6 REPLY) message to the TE 110 . Specifically, if the IPv6 DNS and/or P-CSCF server address from the PCO is needed and sufficient for the user, the MT 120 only sends to the TE 110 according to the IPv6 DNS and/or P-CSCF server address in the PCO DHCPv6 REPLY message. However, if the IPv6 DNS and/or P-CSCF server address from the PCO is not needed and sufficient for the user, then the MT 120 further sends the IPv6 DNS and/or SIP server address in the non-volatile memory to the TE 110 Send a DHCPv6 REPLY message.
图3是根据本发明第二实施例描述的移动通信系统中获取IPv6 DNS及/或SIP服务器地址的消息时序图。如图3所示，在步骤S310中，MT 120与服务网络130通过激活分组数据协议上下文请求/激活分组数据协议上下文接收消息启动分组数据协议上下文激活进程。在本实施例中，在步骤S310，MT 120与服务网络130可启动缺省EPS承载上下文激活进程、UE请求分组数据网络连接进程或EPS服务的长期演进附着进程。通过ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST消息启动缺省EPS承载上下文激活进程用于接收PCO信息，其中ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST消息可包含下列信息元：协议鉴别符、EPS承载标识、进程交易标识、激活缺省EPS承载上下文请求消息标识、EPS QoS、APN与公共数据网地址。当激活了PDP上下文激活进程、缺省EPS承载上下文激活进程、UE请求PDN连接进程或EPS服务的长期演进附着进程并且MT 120不能从PCO得到IPv6 DNS及/或P-CSCF服务器地址时，在步骤S320中，MT 120可从具有预存IPv6 DNS及/或SIP服务器地址的非易失性存储器中得到IPv6 DNS及/或SIP服务器地址。当在步骤S330来自服务网络130的路由器通告的O旗标设定为0时，则在步骤S340中MT 120可将路由器通告的O旗标设定为1并且将路由器通告(O旗标等于1)发送至TE 110。当TE 110接收路由器通告(O旗标等于1)时，在步骤S350，TE 110可向MT 120发送DHCPv6 INFORMATION-REQUEST消息。当MT 120从TE 110接收DHCPv6 INFORMATION-REQUEST消息时，在步骤S360，MT 120可根据非易失性存储器中的IPv6 DNS及/或SIP服务器地址向TE 110发送DHCPv6 REPLY消息。Fig. 3 is a sequence diagram of messages for obtaining IPv6 DNS and/or SIP server addresses in the mobile communication system according to the second embodiment of the present invention. As shown in FIG. 3 , in step S310 , the MT 120 and the service network 130 start the packet data protocol context activation process through an activate packet data protocol context request/activate packet data protocol context receive message. In this embodiment, in step S310, the MT 120 and the serving network 130 may start a default EPS bearer context activation process, a UE request packet data network connection process or a long term evolution attach process for EPS services. The default EPS bearer context activation process is started through the ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST message to receive PCO information. The ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message can contain the following information elements: protocol discriminator, EPS bearer ID, process transaction ID, activation default EPS bearer context request message identifier, EPS QoS, APN and public data network address. When the PDP context activation process, the default EPS bearer context activation process, the UE request PDN connection process or the long-term evolution attachment process of the EPS service are activated and the MT 120 cannot obtain the IPv6 DNS and/or P-CSCF server address from the PCO, in step In S320, the MT 120 may obtain the IPv6 DNS and/or SIP server address from a non-volatile memory with pre-stored IPv6 DNS and/or SIP server addresses. When the 0 flag of the router advertisement from the serving network 130 is set to 0 in step S330, then in step S340 the MT 120 may set the 0 flag of the router advertisement to 1 and set the router advertisement (0 flag equal to 1 ) to TE 110. When the TE 110 receives the router advertisement (the O flag is equal to 1), the TE 110 may send a DHCPv6 INFORMATION-REQUEST message to the MT 120 at step S350. When MT 120 receives the DHCPv6 INFORMATION-REQUEST message from TE 110, in step S360, MT 120 may send a DHCPv6 REPLY message to TE 110 according to the IPv6 DNS and/or SIP server address in the non-volatile memory.
图4是根据本发明第三实施例描述的移动通信系统中获取IPv6 DNS及/或SIP服务器地址的消息时序图。如图4所示，在步骤S410中，MT 120与服务网络130通过激活分组数据协议上下文请求/激活分组数据协议上下文接收消息启动分组数据协议上下文激活进程。在本实施例中，在步骤S410，MT 120与服务网络130可启动缺省EPS承载上下文激活进程、UE请求分组数据网络连接进程或EPS服务的长期演进附着进程。通过ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST消息启动缺省EPS承载上下文激活进程用于接收PCO信息，其中ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST消息可包含下列信息元：协议鉴别符、EPS承载标识、进程交易标识、激活缺省EPS承载上下文请求消息标识、EPS QoS、APN与公共数据网地址。当激活了PDP上下文激活进程、缺省EPS承载上下文激活进程、UE请求PDN连接进程或EPS服务的长期演进附着进程时，在步骤S420中，MT 120可从PCO中得到IPv6 DNS及/或P-CSCF服务器地址。值得注意的是，P-CSCF服务器是一种IMS终端的第一接触点的SIP服务器。当前3GPP标准中指定的P-CSCF发现包含在会话管理进程期间请求PCO中的P-CSCF地址供应。在本实施例中，某些IPv6 DNS及/或SIP服务器地址可预存在MT 120的非易失性存储器中，因此MT 120也可从非易失性存储器得到IPv6 DNS及/或SIP服务器地址。当在步骤S430来自服务网络130的路由器通告的O旗标设定为1时，则在步骤S440中MT 120可保留路由器通告的O旗标的设定值(即O旗标等于1)并且向TE 110发送路由器通告(O旗标等于1)。当TE 110接收路由器通告(O旗标等于1)时，在步骤S450，TE 110可向MT 120发送DHCPv6INFORMATION-REQUEST消息。接着在步骤S460，MT 120向服务网络130发送DHCPv6INFORMATION-REQUEST消息。当服务网络130从MT 120接收DHCPv6 INFORMATION-REQUEST消息时，在步骤S470，服务网络130可向MT 120发送DHCPv6 REPLY消息。接着在步骤S480，MT120向TE 110发送DHCPv6 REPLY消息。在本实施例中，MT 120在向TE 110发送DHCPv6 REPLY消息之前，MT 120可根据PCO中的IPv6 DNS及/或P-CSCF服务器地址及/或非易失性存储器中的预存IPv6 DNS及/或SIP服务器地址修改服务网络130发送的DHCPv6 REPLY消息。具体地，如果服务网络130发送的DHCPv6 REPLY消息中的IPv6 DNS及/或SIP服务器地址对于用户是需要的和足够的，则MT 120向TE 110发送DHCPv6 REPLY消息。然而，如果服务网络130发送的DHCPv6 REPLY消息中的IPv6 DNS及/或SIP服务器地址对于用户不是需要的和足够的，则MT 120可根据PCO中的IPv6 DNS及/或P-CSCF服务器地址及/或非易失性存储器中的IPv6 DNS及/或SIP服务器地址修改DHCPv6 REPLY消息并且将已修改的DHCPv6 REPLY消息发送至TE 110。Fig. 4 is a sequence diagram of messages for obtaining IPv6 DNS and/or SIP server addresses in the mobile communication system according to the third embodiment of the present invention. As shown in FIG. 4 , in step S410 , the MT 120 and the service network 130 start the packet data protocol context activation process through an activate packet data protocol context request/activate packet data protocol context receive message. In this embodiment, in step S410, the MT 120 and the service network 130 may start a default EPS bearer context activation process, a UE request packet data network connection process or a long term evolution attach process for EPS services. The default EPS bearer context activation process is started through the ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST message to receive PCO information. The ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message can contain the following information elements: protocol discriminator, EPS bearer ID, process transaction ID, activation default EPS bearer context request message identifier, EPS QoS, APN and public data network address. When the PDP context activation process, default EPS bearer context activation process, UE request PDN connection process or EPS service long-term evolution attach process is activated, in step S420, MT 120 can obtain IPv6 DNS and/or P- CSCF server address. It should be noted that the P-CSCF server is a SIP server of the first contact point of the IMS terminal. P-CSCF discovery as specified in current 3GPP standards involves requesting P-CSCF address provisioning in the PCO during the session management procedure. In this embodiment, some IPv6 DNS and/or SIP server addresses can be pre-stored in the non-volatile memory of MT 120, so MT 120 can also obtain IPv6 DNS and/or SIP server addresses from the non-volatile memory. When the O flag of the router advertisement from the service network 130 is set to 1 in step S430, then in step S440, the MT 120 may retain the set value of the O flag of the router advertisement (that is, the O flag is equal to 1) and report to the TE 110 Send Router Advertisement (0 flag equal to 1). When TE 110 receives the router advertisement (O flag is equal to 1), TE 110 may send a DHCPv6 INFORMATION-REQUEST message to MT 120 at step S450. Then in step S460 , the MT 120 sends a DHCPv6 INFORMATION-REQUEST message to the service network 130 . When the service network 130 receives the DHCPv6 INFORMATION-REQUEST message from the MT 120, the service network 130 may send a DHCPv6 REPLY message to the MT 120 at step S470. Next in step S480 , MT 120 sends a DHCPv6 REPLY message to TE 110 . In this embodiment, before MT 120 sends a DHCPv6 REPLY message to TE 110, MT 120 may, according to the IPv6 DNS and/or P-CSCF server address in the PCO and/or the pre-stored IPv6 DNS and/or Or a DHCPv6 REPLY message sent by the SIP server address modification service network 130 . Specifically, if the IPv6 DNS and/or SIP server address in the DHCPv6 REPLY message sent by the service network 130 is needed and sufficient for the user, then the MT 120 sends the DHCPv6 REPLY message to the TE 110 . However, if the IPv6 DNS and/or SIP server address in the DHCPv6 REPLY message sent by the service network 130 is not needed and sufficient for the user, then the MT 120 can use the IPv6 DNS in the PCO and/or the P-CSCF server address and/or Or the IPv6 DNS and/or SIP server addresses in non-volatile memory modify the DHCPv6 REPLY message and send the modified DHCPv6 REPLY message to the TE 110 .
图5是根据本发明第四实施例描述的移动通信系统中获取IPv6 DNS及/或SIP服务器地址的消息时序图。如图5所示，在步骤S510中，MT 120与服务网络130通过激活分组数据协议上下文请求/激活分组数据协议上下文接收消息启动分组数据协议上下文激活进程。在本实施例中，在步骤S510，MT 120与服务网络130可启动缺省EPS承载上下文激活进程、UE请求分组数据网络连接进程或EPS服务的长期演进附着进程。通过ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST消息启动缺省EPS承载上下文激活进程用于接收PCO信息，其中ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST消息可包含下列信息元：协议鉴别符、EPS承载标识、进程交易标识、激活缺省EPS承载上下文请求消息标识、EPS QoS、APN与公共数据网地址。当激活了PDP上下文激活进程、缺省EPS承载上下文激活进程、UE请求PDN连接进程或EPS服务的长期演进附着进程并且MT 120不能从PCO得到IPv6 DNS及/或P-CSCF服务器地址时，在步骤S520中，MT 120可从具有预存IPv6 DNS及/或SIP服务器地址的非易失性存储器中得到IPv6 DNS及/或SIP服务器地址。。当在步骤S530来自服务网络130的路由器通告的O旗标设定为1时，则在步骤S540中MT 120可保留路由器通告的O旗标的设定值(即O旗标等于1)并且向TE 110发送路由器通告(O旗标等于1)。当TE 110接收路由器通告(O旗标等于1)时，在步骤S550，TE 110可向MT 120发送DHCPv6 INFORMATION-REQUEST消息。接着在步骤S560，MT 120向服务网络130发送DHCPv6 INFORMATION-REQUEST消息。当服务网络130从MT 120接收DHCPv6 INFORMATION-REQUEST消息时，在步骤S570，服务网络130可向MT 120发送DHCPv6 REPLY消息。接着在步骤S580，MT 120向TE 110发送DHCPv6 REPLY消息。在本实施例中，MT 120在向TE 110发送DHCPv6 REPLY消息之前，MT 120可根据非易失性存储器中的预存IPv6 DNS及/或SIP服务器地址修改服务网络130发送的DHCPv6 REPLY消息。Fig. 5 is a sequence diagram of messages for obtaining IPv6 DNS and/or SIP server addresses in the mobile communication system according to the fourth embodiment of the present invention. As shown in FIG. 5 , in step S510 , the MT 120 and the service network 130 start the packet data protocol context activation process through an activate packet data protocol context request/activate packet data protocol context receive message. In this embodiment, in step S510, the MT 120 and the service network 130 may start a default EPS bearer context activation process, a UE request packet data network connection process or a long term evolution attach process for EPS services. The default EPS bearer context activation process is started through the ACTIVATE DEFAULT EPSBEARER CONTEXT REQUEST message to receive PCO information. The ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message can contain the following information elements: protocol discriminator, EPS bearer ID, process transaction ID, activation default EPS bearer context request message identifier, EPS QoS, APN and public data network address. When the PDP context activation process, the default EPS bearer context activation process, the UE request PDN connection process or the long-term evolution attachment process of the EPS service are activated and the MT 120 cannot obtain the IPv6 DNS and/or P-CSCF server address from the PCO, in step In S520, the MT 120 can obtain the IPv6 DNS and/or SIP server address from the non-volatile memory with the IPv6 DNS and/or SIP server address pre-stored. . When the O flag of the router advertisement from the service network 130 is set to 1 in step S530, then in step S540, the MT 120 may retain the set value of the O flag of the router advertisement (that is, the O flag is equal to 1) and report to the TE 110 Send Router Advertisement (0 flag equal to 1). When TE 110 receives the router advertisement (O flag is equal to 1), TE 110 may send a DHCPv6 INFORMATION-REQUEST message to MT 120 in step S550. Then in step S560 , the MT 120 sends a DHCPv6 INFORMATION-REQUEST message to the service network 130 . When the service network 130 receives the DHCPv6 INFORMATION-REQUEST message from the MT 120, the service network 130 may send a DHCPv6 REPLY message to the MT 120 at step S570. Then in step S580 , MT 120 sends a DHCPv6 REPLY message to TE 110 . In this embodiment, before the MT 120 sends the DHCPv6 REPLY message to the TE 110, the MT 120 may modify the DHCPv6 REPLY message sent by the service network 130 according to the IPv6 DNS and/or SIP server addresses pre-stored in the non-volatile memory.
图6A-6D是根据本发明实施例描述的移动通信装置作为MT的IPv6地址获取方法流程图。首先，在步骤S610，从服务网络接收路由器通告。接着，在步骤S620，确定来自服务网络的路由器通告的O旗标是否已经设定为0。如果来自服务网络的路由器通告的O旗标已经设定为0，则在步骤S630，由MT将路由器通告的O旗标设定为1。如果来自服务网络的路由器通告的O旗标已经设定为1，则在步骤S640，由MT保留路由器通告的O旗标的设定值。6A-6D are flowcharts of a method for obtaining an IPv6 address of a mobile communication device serving as an MT according to an embodiment of the present invention. First, in step S610, a router advertisement is received from a serving network. Next, in step S620, it is determined whether the O flag of the router advertisement from the service network has been set to 0. If the O flag of the router advertisement from the serving network has been set to 0, then in step S630, the MT sets the O flag of the router advertisement to 1. If the O flag of the router advertisement from the serving network has been set to 1, then in step S640, the MT retains the set value of the O flag of the router advertisement.
在步骤S630后，在步骤S631，向TE发送上述路由器通告。在步骤S632，当TE接收了上述路由器通告时从TE向MT发送DHCPv6 INFORMATION-REQUEST消息。在步骤S633，MT可确定MT是否从服务网络中得到IPv6 DNS及/或SIP服务器地址。如果MT从服务网络中得到IPv6DNS及/或SIP服务器地址，则在步骤S634，根据服务网络中的IPv6 DNS及/或SIP服务器地址及/或MT存储器中的预存IPv6 DNS及/或SIP服务器地址，直接从MT发送DHCPv6 REPLY消息至TE。如果MT不能从服务网络中得到IPv6 DNS及/或SIP服务器地址，则在步骤S635，根据MT存储器中的预存IPv6 DNS及/或SIP服务器地址，直接从MT发送DHCPv6 REPLY消息至TE。After step S630, in step S631, send the router advertisement to TE. In step S632, when the TE receives the above router advertisement, a DHCPv6 INFORMATION-REQUEST message is sent from the TE to the MT. In step S633, the MT may determine whether the MT obtains the IPv6 DNS and/or SIP server address from the service network. If the MT obtains the IPv6 DNS and/or SIP server address from the service network, then in step S634, according to the IPv6 DNS in the service network and/or the SIP server address and/or the prestored IPv6 DNS and/or SIP server address in the MT memory, Send DHCPv6 REPLY message directly from MT to TE. If the MT cannot obtain the IPv6 DNS and/or SIP server address from the service network, then in step S635, send a DHCPv6 REPLY message directly from the MT to the TE according to the pre-stored IPv6 DNS and/or SIP server address in the MT memory.
在步骤S640后，在步骤S641，向TE发送路由器通告。在步骤S642，当TE接收了上述路由器通告时从TE向MT发送DHCPv6 INFORMATION-REQUEST消息。在步骤S643，从MT向服务网络发送DHCPv6 INFORMATION-REQUEST消息。在步骤S644，从服务网络向MT发送DHCPv6REPLY消息。在步骤S645，MT可确定MT是否从服务网络中得到IPv6 DNS及/或SIP服务器地址。如果MT从服务网络中得到IPv6 DNS及/或SIP服务器地址，则在步骤S646，MT可根据服务网络中的IPv6 DNS及/或SIP服务器地址及/或存储器中的预存IPv6 DNS及/或SIP服务器地址修改从服务网络发送的DHCPv6 REPLY消息。如果MT不能从服务网络中得到IPv6 DNS及/或SIP服务器地址，则在步骤S647，MT可根据存储器中的预存IPv6 DNS及/或SIP服务器地址修改从服务网络发送的DHCPv6 REPLY消息。在步骤S648，从MT向TE发送DHCPv6 REPLY消息。After step S640, in step S641, a router advertisement is sent to the TE. In step S642, when the TE receives the above router advertisement, a DHCPv6 INFORMATION-REQUEST message is sent from the TE to the MT. In step S643, a DHCPv6 INFORMATION-REQUEST message is sent from the MT to the serving network. In step S644, a DHCPv6 REPLY message is sent from the serving network to the MT. In step S645, the MT may determine whether the MT obtains the IPv6 DNS and/or SIP server address from the service network. If MT obtains IPv6 DNS and/or SIP server address from service network, then in step S646, MT can according to the IPv6 DNS in service network and/or SIP server address and/or the prestored IPv6 DNS and/or SIP server address in memory Address modification DHCPv6 REPLY message sent from the serving network. If the MT cannot obtain the IPv6 DNS and/or SIP server address from the serving network, then in step S647, the MT can modify the DHCPv6 REPLY message sent from the serving network according to the pre-stored IPv6 DNS and/or SIP server address in the memory. In step S648, a DHCPv6 REPLY message is sent from the MT to the TE.
因此，在本方法中当未设定路由器通告消息的O旗标或者不存在来自服务网络的IPv6 DNS及/或SIP服务器地址回复分组时，TE可获得IPv6 DNS及/或SIP服务器地址。Therefore, in this method, when the O flag of the RA message is not set or there is no IPv6 DNS and/or SIP server address reply packet from the serving network, the TE can obtain the IPv6 DNS and/or SIP server address.
