终端发起AGPS定位时，需要将SUPL域名发送至DNS服务器，请求DNS服务器对SUPL域名进行解析，获得SUPL域名对应的多个IP地址，通过上述多个IP地址中的一个接入SUPL服务器。但是，在一些运营商网络下并非是解析后的所有IP地址均可用，如果接入不可用的IP地址，会造成AGPS无法正常工作。When the terminal initiates AGPS positioning, it needs to send the SUPL domain name to the DNS server, request the DNS server to resolve the SUPL domain name, obtain multiple IP addresses corresponding to the SUPL domain name, and access the SUPL server through one of the above multiple IP addresses. However, in some operator networks, not all resolved IP addresses are available. If unavailable IP addresses are accessed, AGPS will not work properly.
为了提高终端接入SUPL域名对应的IP地址的成功率与效率，本申请提出了一种AGPS定位启动方法，可以在终端中存储成功接入过的SUPL服务器的IP地址，后续的AGPS定位过程中，终端可以基于上述成功接入过的IP地址，去选择所要接入的SUPL服务器的IP地址。示例性的，如图1所示，示出了本申请一个示例性实施例提供的AGPS定位启动方法的流程图，该方法由终端执行，该方法包括：In order to improve the success rate and efficiency of the terminal accessing the IP address corresponding to the SUPL domain name, the present application proposes an AGPS positioning start method, which can store the IP address of the SUPL server that has been successfully accessed in the terminal. In the subsequent AGPS positioning process, the terminal can select the IP address of the SUPL server to be accessed based on the above-mentioned successfully accessed IP address. Exemplarily, as shown in FIG1, a flowchart of the AGPS positioning start method provided by an exemplary embodiment of the present application is shown, and the method is executed by the terminal, and the method includes:
步骤101，发起AGPS定位。Step 101: Initiate AGPS positioning.
示例性的，终端运行的应用程序请求定位服务，终端发起AGPS定位；或者，终端运行的操作系统请求定位服务，终端发起AGPS定位。For example, the application running on the terminal requests positioning services, and the terminal initiates AGPS positioning; or the operating system running on the terminal requests positioning services, and the terminal initiates AGPS positioning.
步骤102，连接DNS服务器。Step 102, connect to the DNS server.
终端在发起AGPS定位之后，连接DNS服务器；响应于终端成功连接DNS服务器，执行步骤103；响应于终端连接DNS服务器失败，执行步骤105。After initiating AGPS positioning, the terminal connects to the DNS server; in response to the terminal successfully connecting to the DNS server, step 103 is executed; in response to the terminal failing to connect to the DNS server, step 105 is executed.
步骤103，SUPL域名解析。Step 103, SUPL domain name resolution.
终端向DNS服务器发送域名解析请求，域名解析请求中携带有SUPL域名；由DNS服务器响应域名解析请求，对SUPL域名进行解析，得到至少两个IP地址；终端接收DNS服务器的反馈信息；响应于上述反馈信息包括SUPL域名对应的至少两个IP地址，终端确定SUPL域名解析成功，执行步骤104；响应于上述反馈信息指示SUPL域名解析失败，执行步骤105。The terminal sends a domain name resolution request to the DNS server, and the domain name resolution request carries the SUPL domain name; the DNS server responds to the domain name resolution request, parses the SUPL domain name, and obtains at least two IP addresses; the terminal receives feedback information from the DNS server; in response to the above The feedback information includes at least two IP addresses corresponding to the SUPL domain name. The terminal determines that the SUPL domain name resolution is successful and proceeds to step 104; in response to the feedback information indicating that the SUPL domain name resolution fails, the terminal proceeds to step 105.
步骤104，对比本地IP地址数据库。Step 104, compare with the local IP address database.
终端中设置有本地IP地址数据库，本地IP地址数据库中存储有IP列表，IP列表中SUPL域名与IP地址一一对应存储，其中，IP列表中存储的IP地址是终端在历史过程中从DNS服务器中获取的且成功接入过的IP地址；终端从IP列表中查询得到与上述一个SUPL域名对应的本地IP地址，将上述至少两个IP地址分别与上述本地IP地址进行匹配；响应于上述至少两个IP地址中存在上述本地IP地址，也即在上述至少两个IP地址中匹配到与本地IP地址相同的IP地址，优先接入至少两个IP地址中的本地IP地址，执行步骤108；响应于上述至少两个IP地址均与上述本地IP地址不同，执行步骤105。A local IP address database is set up in the terminal. An IP list is stored in the local IP address database. The SUPL domain name and IP address in the IP list are stored in one-to-one correspondence. Among them, the IP addresses stored in the IP list are obtained by the terminal from the DNS server in the historical process. The IP address obtained from and successfully accessed; the terminal queries the IP list to obtain the local IP address corresponding to the above-mentioned SUPL domain name, and matches the above-mentioned at least two IP addresses with the above-mentioned local IP address respectively; in response to the above-mentioned at least The above-mentioned local IP address exists in the two IP addresses, that is, the IP address that is the same as the local IP address is matched among the above-mentioned at least two IP addresses, and the local IP address among the at least two IP addresses is preferentially accessed, and step 108 is executed; In response to the at least two IP addresses being different from the local IP address, step 105 is performed.
步骤105，优先本地IP地址数据库。Step 105: Prioritize the local IP address database.
响应于本地IP地址数据库中存储有SUPL域名对应的本地IP地址，终端优先接入本地IP地址；终端接入本地IP地址成功，执行步骤108；终端接入本地IP地址失败，执行步骤106。In response to the local IP address corresponding to the SUPL domain name being stored in the local IP address database, the terminal preferentially accesses the local IP address; if the terminal successfully accesses the local IP address, perform step 108; if the terminal fails to access the local IP address, perform step 106.
步骤106，DNS服务器提供的第一IP地址。Step 106, the first IP address provided by the DNS server.
示例性的，在至少两个IP地址包括本地IP地址的情况下，第一IP地址是指至少两个IP地址中除本地IP地址之外的IP地址；在至少两个IP地址不包括本地IP地址的情况下，第一IP地址是指至少两个IP地址中的任意IP地址。终端接入第一IP地址；终端接入第一IP地址成功，执行步骤107和步骤108。For example, when at least two IP addresses include local IP addresses, the first IP address refers to the IP address other than the local IP address among the at least two IP addresses; when at least two IP addresses do not include local IP addresses, In the case of addresses, the first IP address refers to any IP address among at least two IP addresses. The terminal accesses the first IP address; the terminal accesses the first IP address successfully and executes steps 107 and 108.
示例性的，终端在接入本地IP地址失败的情况下，从剩余IP地址中选取一个第一IP地址接入，响应于成功接入第一IP地址，执行步骤107和步骤108；其中，剩余IP地址包括至少两个IP地址中除本地IP地址之外的至少一个IP地址。Exemplarily, when the terminal fails to access the local IP address, it selects a first IP address from the remaining IP addresses to access, and in response to successfully accessing the first IP address, performs steps 107 and 108; wherein, the remaining The IP address includes at least one IP address other than the local IP address among the at least two IP addresses.
在一些实施例中，第一IP地址可以包括至少两个，终端在接入一个第一IP地址失败的情况下，接入另一个第一IP地址。In some embodiments, the first IP address may include at least two, and when the terminal fails to access one first IP address, the terminal accesses another first IP address.
在一些实施例中，终端接入第一IP地址失败之后，还可以再次向DNS服务器发送域名解析请求，向DNS服务器重新请求SUPL域名对应的IP地址，直至终端成功接入SUPL服务器。比如，终端在第一IP地址接入失败的情况下，返回步骤103。In some embodiments, after the terminal fails to access the first IP address, it can send a domain name resolution request to the DNS server again, and re-request the IP address corresponding to the SUPL domain name from the DNS server until the terminal successfully accesses the SUPL server. For example, if the terminal fails to access the first IP address, it returns to step 103.
步骤107，更新本地IP地址数据库。Step 107: Update the local IP address database.
终端将SUPL域名与成功接入的第一IP地址对应更新至本地IP地址数据库。示例性的，终端将SUPL域名与成功接入的第一IP地址对应更新至本地存储的IP列表中。The terminal updates the correspondence between the SUPL domain name and the successfully accessed first IP address to the local IP address database. Exemplarily, the terminal updates the correspondence between the SUPL domain name and the successfully accessed first IP address into the locally stored IP list.
步骤108，启动AGPS。Step 108: Start AGPS.
示例性的，终端接入第一IP地址成功，启动AGPS。Exemplarily, the terminal successfully accesses the first IP address and starts AGPS.
或者，终端接入本地IP地址成功，启动AGPS。Or, the terminal successfully accesses the local IP address and starts AGPS.
综上所述，本实施例提供的AGPS定位启动方法，终端连接到DNS服务器，从DNS服务器中解析SUPL域名，得到至少两个IP地址；之后，在本地存储有上述SUPL域名对应的本地IP地址、且至少两个IP地址中存在本地IP地址的情况下，优先选择接入本地IP地址，由于本地IP地址是先前终端成功接入过的IP地址，这样能够提高终端连接SUPL服务器的成功率，大概率地避免了终端需要多次尝试连接SUPL服务器的情况，进一步地提高了成功连接SUPL服务器的效率。To sum up, in the AGPS positioning startup method provided by this embodiment, the terminal connects to the DNS server, parses the SUPL domain name from the DNS server, and obtains at least two IP addresses; then, the local IP address corresponding to the above SUPL domain name is stored locally. , and when there is a local IP address in at least two IP addresses, the local IP address is preferred. Since the local IP address is the IP address that the terminal has successfully accessed before, this can improve the success rate of the terminal connecting to the SUPL server. It is highly likely to avoid the situation where the terminal needs to try to connect to the SUPL server multiple times, further improving the efficiency of successfully connecting to the SUPL server.
其次，在无法连接到DNS服务器的情况下，或者在解析SUPL域名失败的情况下，终端还可以从本地存储中获得SUPL域名对应的本地IP地址，使得终端在无法通过解析SUPL域名获得IP地址的情况下，也存在成功接入SUPL服务器的可能，进一步提高了接入SUPL服务器的成功率。终端还在本地IP地址不可用的情况下及时对其更新，以进一步地保证本地IP地址的可用性。Secondly, when it cannot connect to the DNS server, or when it fails to resolve the SUPL domain name, the terminal can also obtain the local IP address corresponding to the SUPL domain name from local storage, so that the terminal cannot obtain the IP address by parsing the SUPL domain name. In this case, there is also the possibility of successfully accessing the SUPL server, further improving the success rate of accessing the SUPL server. The terminal also updates the local IP address in time when it is unavailable to further ensure the availability of the local IP address.

步骤330，成功接入本地IP地址，启动AGPS定位。Step 330: Successfully access the local IP address and start AGPS positioning.
终端在获得本地IP地址之后，接入本地IP地址；响应接入本地IP地址成功，启动AGPS定位。After obtaining the local IP address, the terminal accesses the local IP address; in response to successful access to the local IP address, AGPS positioning is started.
综上所述，本实施例提供的AGPS定位启动方法，终端在启动AGPS定位的过程中，可以从本地存储中查询是否存在SUPL域名对应的本地IP地址，在查询到SUPL域名对应的本地IP地址的情况下，直接接入本地IP地址，这一本地IP地址是终端在历史AGPS定位过程中从DNS服务器中获得的IP地址，且终端成功接入过本地IP地址，选择接入本地IP地址，能够成功接入SUPL服务器的成功率高，也即提高了终端一次接入SUPL的成功率，大概率地避免了多次尝试连接SUPL服务器的情况，进而提高了成功连接SUPL服务器的效率。且成功接入本地IP地址之后，不再需要向DNS服务器请求SUPL域名解析，节省了对SUPL域名解析获取IP地址的步骤，减少了AGPS定位所需花费的时间，进一步地提高成功连接SUPL服务器的效率。In summary, in the AGPS positioning start method provided by the present embodiment, during the process of starting AGPS positioning, the terminal can query whether there is a local IP address corresponding to the SUPL domain name from the local storage, and directly access the local IP address when the local IP address corresponding to the SUPL domain name is queried. This local IP address is the IP address obtained by the terminal from the DNS server during the historical AGPS positioning process, and the terminal has successfully accessed the local IP address. Selecting to access the local IP address can increase the success rate of successfully accessing the SUPL server, that is, the success rate of the terminal accessing the SUPL once is improved, and the situation of multiple attempts to connect to the SUPL server is avoided with a high probability, thereby improving the efficiency of successfully connecting to the SUPL server. After successfully accessing the local IP address, it is no longer necessary to request the DNS server for SUPL domain name resolution, which saves the step of resolving the SUPL domain name to obtain the IP address, reduces the time required for AGPS positioning, and further improves the efficiency of successfully connecting to the SUPL server.
示例性的，存在终端接入本地IP地址失败的情况，在这种情况下，终端可以尝试接入从DNS服务器获取的SUPL域名对应的IP地址。For example, there may be a situation where the terminal fails to access the local IP address. In this case, the terminal may try to access the IP address corresponding to the SUPL domain name obtained from the DNS server.
示例性的，如图4所示，如果终端在向DNS服务器请求解析SUPL域名之前，直接尝试接入本地IP地址，终端在接入本地IP失败的情况下，可以执行如下步骤：For example, as shown in Figure 4, if the terminal directly attempts to access the local IP address before requesting the DNS server to resolve the SUPL domain name, and the terminal fails to access the local IP, it can perform the following steps:
步骤340，响应于接入本地IP地址失败，从DNS服务器中解析SUPL域名，获得至少一个IP地址。Step 340: In response to the failure to access the local IP address, resolve the SUPL domain name from the DNS server and obtain at least one IP address.
终端响应本地IP地址接入失败，向DNS服务器发送域名解析请求，域名解析请求中携带SUPL域名，用于请求DNS服务器对SUPL域名进行解析，以获得至少一个IP地址；接收DNS服务器反馈的至少一个IP地址。The terminal responds to the local IP address access failure and sends a domain name resolution request to the DNS server. The domain name resolution request carries the SUPL domain name and is used to request the DNS server to resolve the SUPL domain name to obtain at least one IP address; receive at least one feedback from the DNS server. IP address.
步骤350，成功接入至少一个IP地址中的第二IP地址，启动AGPS定位。Step 350: Successfully access the second IP address among at least one IP address and start AGPS positioning.
示例性的，终端从至少一个IP地址中随机选取一个第二IP地址接入；响应于接入第二IP地址成功，启动AGPS定位。Exemplarily, the terminal randomly selects a second IP address from at least one IP address to access; in response to successfully accessing the second IP address, AGPS positioning is initiated.
可选地，响应于成功接入第二IP地址，终端还将SUPL域名与第二IP地址对应更新至本地存储。Optionally, in response to successfully accessing the second IP address, the terminal also updates the correspondence between the SUPL domain name and the second IP address to the local storage.
示例性的，SUPL域名与IP地址对应存储在本地存储的IP列表中；终端在成功接入第二IP地址的情况下，将SUPL域名与第二IP地址对应更新至本地存储的IP列表中。比如，终端将IP列表中SUPL域名对应的本地IP地址更新为第二IP地址。For example, the SUPL domain name and the IP address are correspondingly stored in a locally stored IP list; when the terminal successfully accesses the second IP address, the SUPL domain name and the second IP address are updated to the locally stored IP list. For example, the terminal updates the local IP address corresponding to the SUPL domain name in the IP list to the second IP address.
综上所述，本实施例提供的AGPS定位启动方法，在AGPS定位启动方法启动过程中，在本地存储有SUPL域名对应的本地IP地址的情况下，优先接入本地IP地址，在接入本地IP地址失败后，再从DNS服务器中解析获取SUPL域名对应的IP地址。由于各个运营商的SUPL服务器IP地址不会经常性更换，因此，采用本地IP地址接入成功的概率高，一旦接入本地IP地址成功，则无需从DNS服务器获取SUPL域名对应的IP地址，能够节省AGPS定位启动所需花费的时间，提高了AGPS定位的效率。To sum up, in the AGPS positioning startup method provided by this embodiment, during the startup process of the AGPS positioning startup method, when the local IP address corresponding to the SUPL domain name is stored locally, the local IP address is given priority. After the IP address fails, the IP address corresponding to the SUPL domain name is obtained from the DNS server. Since the IP addresses of the SUPL servers of each operator do not change frequently, the probability of successful access using the local IP address is high. Once the access to the local IP address is successful, there is no need to obtain the IP address corresponding to the SUPL domain name from the DNS server. It saves the time required to start AGPS positioning and improves the efficiency of AGPS positioning.
其次，如果接入本地IP地址失败，且从DNS服务器中获取的IP地址接入成功，终端还将本次成功接入的IP地址与SUPL域名对应更新至IP列表，以保证SUPL域名对应的本地IP地址的可用性。Secondly, if access to the local IP address fails and the IP address obtained from the DNS server is successfully accessed, the terminal will also update the IP address corresponding to the SUPL domain name to the IP list to ensure that the local IP address corresponding to the SUPL domain name is successfully accessed. IP address availability.
还存在一种情况，终端在接入IP地址之前，向DNS服务器请求解析SUPL域名，获得至少两个IP地址；如果至少两个IP地址中存在本地IP地址，终端优先选择接入本地IP地址，如图5所示，这一AGPS定位启动方法的示例性实施例如下所示：There is also a situation where the terminal requests the DNS server to resolve the SUPL domain name before accessing the IP address to obtain at least two IP addresses; if there is a local IP address among the at least two IP addresses, the terminal preferentially chooses to access the local IP address, as shown in FIG5 . An exemplary embodiment of this AGPS positioning start method is as follows:
步骤410，获取SUPL域名。Step 410: Obtain the SUPL domain name.
示例性的，上述SUPL域名是一个或者一组SUPL服务器的标识。终端中设置有SUPL服务器对应的SUPL域名；终端在AGPS定位的过程中，读取SUPL域名，以基于SUPL域名解析得到SUPL服务器的IP地址，再接入上述SUPL服务器的IP地址，启动AGPS定位。For example, the above-mentioned SUPL domain name is the identifier of one or a group of SUPL servers. The terminal is set with the SUPL domain name corresponding to the SUPL server; during the AGPS positioning process, the terminal reads the SUPL domain name to obtain the IP address of the SUPL server based on SUPL domain name resolution, and then accesses the IP address of the above-mentioned SUPL server to start AGPS positioning.
示例性的，上述SUPL域名是终端入网时自动设置的；或者，上述SUPL域名是由用户自主设置的。For example, the above-mentioned SUPL domain name is automatically set when the terminal accesses the network; or the above-mentioned SUPL domain name is set independently by the user.
示例性的，终端上运行的应用程序请求AGPS定位，终端从自身存储器上读取SUPL域名。或者，终端上运行的操作系统请求AGPS定位，终端从自身存储器上读取SUPL域名。For example, the application running on the terminal requests AGPS positioning, and the terminal reads the SUPL domain name from its own memory. Or, the operating system running on the terminal requests AGPS positioning, and the terminal reads the SUPL domain name from its own memory.
步骤420，从DNS服务器中解析SUPL域名，获得至少两个IP地址。Step 420: Resolve the SUPL domain name from the DNS server to obtain at least two IP addresses.
终端向DNS服务器发送域名解析请求，域名解析请求中携带有SUPL域名；之后由DNS服务器对SUPL域名进行解析，获得SUPL域名对应的至少两个IP地址，将至少两个SUPL域名反馈给终端；终端接收DNS服务器反馈的至少两个SUPL域名。The terminal sends a domain name resolution request to the DNS server, and the domain name resolution request carries the SUPL domain name; the DNS server then parses the SUPL domain name, obtains at least two IP addresses corresponding to the SUPL domain name, and feeds back at least two SUPL domain names to the terminal; the terminal Receive at least two SUPL domain names fed back by the DNS server.
示例性的，DNS服务器中存储有SUPL域名与IP地址的对应关系表；终端向DNS服务器发送域名解析请求之后，由DNS服务器基于上述对应关系表对SUPL域名进行解析，解析出与SUPL域名对应的至少两个IP地址，将上述至少两个IP地址返回给终端，则终端即可获得SUPL域名对应的至少两个IP地址。For example, the DNS server stores a correspondence table between the SUPL domain name and the IP address; after the terminal sends a domain name resolution request to the DNS server, the DNS server parses the SUPL domain name based on the above correspondence table and parses out the IP address corresponding to the SUPL domain name. At least two IP addresses, return the above at least two IP addresses to the terminal, then the terminal can obtain at least two IP addresses corresponding to the SUPL domain name.
步骤430，从终端的本地存储中查询到SUPL域名对应的本地IP地址；本地IP地址是终端在历史AGPS定位过程中，从DNS服务器中获得的且成功接入过的IP地址。Step 430, query the local IP address corresponding to the SUPL domain name from the local storage of the terminal; the local IP address is the IP address that the terminal has successfully accessed and obtained from the DNS server during the historical AGPS positioning process.

步骤440，响应于至少两个IP地址中存在本地IP地址，优先接入本地IP地址。Step 440: In response to the local IP address being present in the at least two IP addresses, the local IP address is preferentially accessed.
终端确定至少两个IP地址中存在与本地IP地址相同的IP地址，优先接入本地IP地址。The terminal determines that at least two IP addresses have the same IP address as the local IP address, and accesses the local IP address first.
示例性的，终端本地存储有IP列表，该IP列表中一一对应存储有SUPL域名与IP地址。终端获得至少两个IP地址之后，将至少两个IP地址分别与本地IP地址进行匹配；在至少两个IP地址中存在本地IP地址的情况下，优先接入本地IP地址。For example, the terminal locally stores an IP list, and the IP list stores SUPL domain names and IP addresses in one-to-one correspondence. After the terminal obtains at least two IP addresses, it matches the at least two IP addresses with the local IP address respectively; if there is a local IP address in the at least two IP addresses, the local IP address is given priority.
比如，终端遍历至少两个IP地址，确定至少两个IP地址中是否存在本地IP地址；在至少两个IP地址中存在本地IP地址的情况下，优先接入本地IP地址。或者，终端将至少两个IP地址依次与本地IP地址进行匹配；直至匹配到与本地IP地址相同的IP地址，优先接入本地IP地址。For example, the terminal traverses at least two IP addresses to determine whether there is a local IP address in at least two IP addresses; if there is a local IP address in at least two IP addresses, the local IP address is given priority. Or, the terminal matches at least two IP addresses with the local IP address in sequence; until an IP address that is the same as the local IP address is matched, the local IP address is given priority.
比如，上述至少两个IP地址包括“XX.XXX.XXX.xx”、“XX.XXX.XXX.yy”和“XX.XXX.XXX.zz”这三个IP地址；在本地存储的IP列表中与SUPL域名对应存储的本地IP地址为“XX.XXX.XXX.yy”；终端与上述三个IP地址依次匹配，在匹配到与第2个IP地址“XX.XXX.XXX.yy”相同时，不再继续与第三个IP地址匹配，选择优先接入本地IP地址“XX.XXX.XXX.yy”。For example, the above-mentioned at least two IP addresses include the three IP addresses of "XX.XXX.XXX.xx", "XX.XXX.XXX.yy" and "XX.XXX.XXX.zz"; the locally stored IP list The local IP address stored corresponding to the SUPL domain name is "XX.XXX.XXX.yy"; the terminal matches the above three IP addresses in sequence, and then matches the second IP address "XX.XXX.XXX.yy" At the same time, it will no longer continue to match the third IP address, and choose to access the local IP address "XX.XXX.XXX.yy" first.

综上所述，本实施例提供的AGPS定位启动方法，终端在启动AGPS定位的过程中，连接到DNS服务器，请求对SUPL域名进行解析，得到SUPL域名对应的多个IP地址；之后，终端在本地存储有上述SUPL域名对应的本地IP地址的情况下，确定多个IP地址中的第一IP地址与本地IP地址相同，则在多个IP地址中选择优先接入第一IP地址，由于本地IP地址是先前终端成功接入过的IP地址，优先选择接入第一IP地址，能够提高终端连接SUPL服务器的成功率，大概率地避免了多次尝试连接SUPL服务器的情况，进一步地提高了成功连接SUPL服务器的效率。To sum up, in the AGPS positioning startup method provided in this embodiment, during the process of starting AGPS positioning, the terminal connects to the DNS server, requests to parse the SUPL domain name, and obtains multiple IP addresses corresponding to the SUPL domain name; after that, the terminal When the local IP address corresponding to the above SUPL domain name is stored locally and it is determined that the first IP address among the multiple IP addresses is the same as the local IP address, then the first IP address among the multiple IP addresses is selected to access first. Since the local The IP address is the IP address that the terminal has successfully accessed before. The first IP address is given priority, which can improve the success rate of the terminal connecting to the SUPL server and avoid multiple attempts to connect to the SUPL server with a high probability, further improving the The efficiency of successfully connecting to the SUPL server.
如果从DNS服务器解析SUPL域名得到的IP地址中，不存在SUPL域名对应的本地IP地址，终端仍可以选择优先接入本地IP地址，示例性的，如图6所示，在图5所示实施例的基础上，增加一个步骤460，如下所示：If there is no local IP address corresponding to the SUPL domain name in the IP address obtained by parsing the SUPL domain name from the DNS server, the terminal can still choose to give priority to the local IP address. For example, as shown in Figure 6, the implementation is shown in Figure 5 Based on the example, add a step 460 as follows:
步骤460，响应于至少两个IP地址均与本地IP地址不同，优先接入本地IP地址。Step 460: In response to at least two IP addresses being different from the local IP address, access the local IP address first.
终端确定至少两个IP地址均与本地IP地址不同，优先接入本地IP地址。The terminal determines that at least two IP addresses are different from the local IP address, and accesses the local IP address first.
示例性的，终端本地存储有IP列表，该IP列表中一一对应存储有SUPL域名与IP地址。终端获得至少两个IP地址之后，将至少两个IP地址分别与本地IP地址进行匹配；在至少两个IP地址均与本地IP地址不同的情况下，优先接入本地IP地址。Exemplarily, the terminal locally stores an IP list, in which the SUPL domain name and the IP address are stored in a one-to-one correspondence. After obtaining at least two IP addresses, the terminal matches the at least two IP addresses with the local IP address respectively; when the at least two IP addresses are different from the local IP address, the local IP address is preferentially accessed.
比如，终端遍历至少两个IP地址，确定至少两个IP地址中是否存在本地IP地址；在至少两个IP地址中不存在本地IP地址的情况下，优先接入本地IP地址。For example, the terminal traverses at least two IP addresses to determine whether a local IP address exists in the at least two IP addresses; if the local IP address does not exist in the at least two IP addresses, the local IP address is preferentially accessed.
比如，上述至少两个IP地址包括“YY.YYY.YYY.xx”、“YY.YYY.YYY.yy”和“YY.YYY.YYY.zz”这三个IP地址；在本地存储的IP列表中与SUPL域名对应存储的本地IP地址为“YY.YYY.YYY.qq”；终端与上述三个IP地址依次匹配，在确定上述三个IP地址均与本地IP地址不同时，选择优先接入本地IP地址“YY.YYY.YYY.qq”。For example, the above-mentioned at least two IP addresses include the three IP addresses of "YY.YYY.YYY.xx", "YY.YYY.YYY.yy" and "YY.YYY.YYY.zz"; the locally stored IP list The local IP address stored corresponding to the SUPL domain name is "YY.YYY.YYY.qq"; the terminal matches the above three IP addresses in sequence. When it is determined that the above three IP addresses are different from the local IP address, select priority access Local IP address "YY.YYY.YYY.qq".
示例性的，终端优先接入本地IP地址成功的情况下，执行步骤450。For example, if the terminal successfully accesses the local IP address preferentially, step 450 is performed.
综上所述，本实施例提供的AGPS定位启动方法，在解析SUPL域名得到的多个IP地址中不存在任何IP地址与本地IP地址相同，这时终端优先选择接入本地IP地址，由于本地IP地址是先前终端成功接入过的IP地址，优先选择接入本地IP地址，能够提高终端连接SUPL服务器的成功率，大概率地避免了多次尝试连接SUPL服务器的情况，进一步地提高了成功连接SUPL服务器的效率。In summary, in the AGPS positioning startup method provided by the present embodiment, there is no IP address that is the same as the local IP address among the multiple IP addresses obtained by resolving the SUPL domain name. At this time, the terminal preferentially chooses to access the local IP address. Since the local IP address is an IP address that the terminal has successfully accessed before, the local IP address is preferentially selected to access, which can improve the success rate of the terminal connecting to the SUPL server, and avoids the situation of multiple attempts to connect to the SUPL server with a high probability, and further improves the efficiency of successfully connecting to the SUPL server.

For example, when the terminal successfully accesses the first IP address, the terminal updates the correspondence between the SUPL domain name and the first IP address to the terminal's locally stored IP list. It should be noted that the terminal can respond to the successful access of the first IP address and sequentially perform the steps of initiating AGPS positioning and IP list update, or it can respond to the successful access of the first IP address and simultaneously perform the steps of initiating AGPS positioning and IP list update. .
示例性的，第一IP地址包括至少两个，在一个第一IP地址接入失败的情况下，选取另一个第一IP地址接入，直至终端成功接入SUPL服务器，还将接入成功的第一IP地址与SUPL域名对应更新至本地存储的IP列表。Exemplarily, the first IP addresses include at least two. When one first IP address fails to access, another first IP address is selected for access until the terminal successfully accesses the SUPL server, and the correspondence between the successfully accessed first IP address and the SUPL domain name is updated to the locally stored IP list.
在一些实施例中，终端接入本地IP地址与第一IP地址均失败的情况下，终端重新向DNS服务器请求解析SUPL域名，之后再次执行步骤440至步骤470。In some embodiments, when the terminal fails to access both the local IP address and the first IP address, the terminal requests the DNS server to resolve the SUPL domain name again, and then performs steps 440 to 470 again.

在一些实施例中，DNS服务器在向终端反馈至少两个IP地址的同时，每个IP地址还标记有当前使用率；终端在接入本地IP地址失败的情况下，可以按照当前使用率由低到高的顺序选择第一IP地址接入。或者，终端在本地存储中不存在本地IP地址的情况下，可以按照当前使用率由低到高的顺序选择第二IP地址接入。比如，第二IP地址1的使用率为0.1，第二IP地址2的使用率为0.6，则终端选择接入第二IP地址1，这是因为使用率高的IP地址，接入的用户终端较多，可能存在接入困难的情况，进而提高了终端接入的成功率与效率。In some embodiments, while the DNS server feeds back at least two IP addresses to the terminal, each IP address is also marked with a current usage rate; if the terminal fails to access the local IP address, it can use the current usage rate from low to low. Select the first IP address in order to access. Alternatively, if the terminal does not have a local IP address in the local storage, the terminal may select the second IP address for access in order of current usage from low to high. For example, if the usage rate of the second IP address 1 is 0.1 and the usage rate of the second IP address 2 is 0.6, then the terminal chooses to access the second IP address 1. This is because the IP address with the high usage rate is connected to the user terminal. If there are too many, access difficulties may occur, thereby improving the success rate and efficiency of terminal access.
综上所述，本实施例提供的AGPS定位启动方法，在解析SUPL域名得到一个IP地址的情况下，仍优先选择接入本地IP地址，以保证成功接入SUPL服务器的概率。To sum up, the AGPS positioning startup method provided in this embodiment still prefers to access the local IP address when parsing the SUPL domain name to obtain an IP address to ensure the probability of successful access to the SUPL server.
