Problems solved by technology

[0007] In the prior art, the amount of data carried by ordinary short messages is very small. For example, a 9K PRL list needs more than 80 short messages. Influenced by factors such as delay, some short messages may be lost, the delay is too long, etc., which will lead to the failure of PRL content update. It is difficult to guarantee the success rate of PRL content update. The success rate of PRL update is relatively low. For large-capacity PRL list, the update success very low rate
The above problems restrict the development of international roaming services and seriously affect the user's international roaming experience
In addition, if the service channel is not removed before the short message is sent, sending dozens of short mes...

Embodiment Construction

[0039] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0040] figure 2 A flowchart showing an embodiment of the method for setting an international roaming preference list of the present invention.

[0041] Such as figure 2 As shown, in step 202, the PRL list is downloaded to the terminal through the PRL MMS using the packet link. For example, the PRL update server constructs a PRL multimedia message according to the PRL list, and pushes the PRL list to the terminal through the PRL multimedia message; or, the PRL update server constructs a PRL short message according to the PRL list, sends the PRL short message to the MMS server, and the MMS server constructs a PRL multimedia message according to the PRL short message , to push the PRL MMS message to the terminal. An example of the PRL MMS format will be introduced later.

[0042] In step 204, th...

Abstract

The invention discloses a preferred roaming list setting method in a CDMA (Code Division Multiple Addressing) system, a system thereof, a terminal and a server. The method comprises the following steps: downloading a preferred roaming list (PRL) to the terminal through a PRL multimedia message; extracting the PRL from the PRL multimedia message to carry out PRL setting of the terminal. According to the method and the system in the invention, the PRL is downloaded to the terminal by utilizing packet link in a multimedia message mode, the terminal sends PRL content to an intelligent card, the intelligent card carries out update on a PRL related file, and an update success rate of the PRL is effectively raised.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method, system, terminal and server for setting a preferred roaming list (Preferred Roaming List, preferred roaming list). Background technique [0002] It is very common for mobile networks that mobile users roam between networks of different countries or different operators. With the increasing mobility of the global population and the increasing number of business contacts, different countries or different mobile operators need to sign roaming agreements so that their own mobile users can enjoy mobile services in as many regions of the world as possible, thereby attracting more Multiple users, increase enterprise operating income, and improve operators' own competitiveness. [0003] In the CDMA (Code Division Multiple Access, Code Division Multiple Access) system, in addition to saving the SID (System Identity, system identification) and frequency o...
