Description

An information synchronization method, system and terminal equipment

technical field

The present invention relates to the communication field, in particular to an information synchronization method, system and terminal equipment.

Background technique

In the future wireless network, the whole network IP (Internet Protocol, Internet Protocol) is the mainstream trend. The design version R99 of the first 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization group) system officially released is backward compatible with the existing GSM circuit switching system, but due to the purchase and maintenance of special hardware equipment for the circuit switching system The cost is very high, and the bandwidth loss for transmitting user data is also very large, so the 3GPP system began to gradually shift to a core network based entirely on IP. This means that due to the increasingly fierce market competition, the existing circuit switching system will be eliminated and replaced by an IP-based hardware system with openness, good scalability, and lower purchase and maintenance costs. Services and applications are also mostly IP-based. Due to the above reasons, the fourth and fifth editions of the 3GPP specifications have increasingly highlighted the importance of the IP architecture and introduced the concept of IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). Users provide traditional circuit switching services (such as voice services), and the second is to provide users with all multimedia services through this subsystem. IMS is an extension of the packet-switching core network, which is intended to be independent from the packet-switching core network after the sixth version of 3GPP. It uses SIP (SessionInitiation Protocol, Session Initiation Protocol) to establish, maintain and terminate voice and multimedia processes.

The PoC (Push to Talk over Cellular) service applied in the whole network IP system will be widely used in future 3G applications. PoC service is a half-duplex voice service that allows a user to establish immediate communication with one or more other users through a specific key. It is the application of VoIP service in the mobile network, which can flexibly provide the functions of "one-to-one" and "one-to-many" group calls. At present, the PoC service is developed based on the SIP application, and has the characteristics of instant communication, group communication, half-duplex, direct answering, and VOIP (Voice Over IP).

In IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) and other network-wide IP systems, PoC (Push to Talk over Cellular) services and other SIP (Session Initiation Protocol, Session Initiation Protocol) application services need to use To SIP URI (Uniform Resource Identifiers, Uniform Resource Identifiers, Uniform Resource Identifiers), EMAIL and other SIP application user information, these user information correspond to the user's TEL URI (Telephone Uniform Resource Identifiers, contact identifier). When the terminal opened the SIP application service, the corresponding relationship between the SIP application user information and the user's TEL URI (telephone number identification) was stored on the SIP application information server.

At present, there is a phonebook synchronization service in the prior art, that is, the contact information stored in the terminal phonebook (such as the correspondence between the contact name and the TEL URI) can be backed up on the user information server on the network side, and the contact information stored in the user information server The person information is synchronized with the contact information stored in the terminal phonebook, and the terminal can synchronize the contact information stored in the local phonebook to the user information server on the network side, so that the user can download the contact information.

There are many SIP application services carried out on the entire network IP system. Different SIP application services have different requirements for user information. Therefore, terminals need to store and maintain different SIP application information corresponding to different SIP application services. These SIP application services The information is related to the contact information stored in the terminal phonebook, but they are different functional entities. For example, in the PoC service, the terminal needs to separately store and maintain a PoC user information list, in which user information such as friend information is stored. This makes the user information to be maintained on the terminal redundant. In addition, different SIP application service terminals need to maintain different SIP application user information, which is not conducive to the unified requirements of various SIP application services for user information, and is not conducive to the development of SIP application services. .

In addition, since the current user information server cannot perform data interaction with the SIP application information server, the terminal cannot download the SIP application user information, resulting in the terminal being unable to update in time when the SIP application user information in the SIP application information server is modified. SIP application user information stored locally.

Step S11, the network server sends the information synchronization request submitted by the terminal to the user information server through the Syncml protocol or the XML protocol or the XCAP protocol or a proprietary protocol, and the user information server judges whether the terminal is stored in the user information server according to the terminal identifier in the request message Corresponding contact information, if yes, execute step S13, otherwise, execute step S12.

Step S12, the user information server returns to the network server a prompt message that the contact information corresponding to the terminal does not exist, and the network server displays the prompt message on the entry page to remind the terminal user.

Step S13, the user information server judges whether the locally stored contact information corresponding to the terminal has the contact identifier specified in the request message, if yes, execute step S15, otherwise, execute step S14.

Step S14 , the user information server returns a prompt message that the specified contact identifier does not exist to the network server, and the network server displays the prompt message on the entry page to remind the terminal user.

Step S15, the user information server sends an information synchronization request to the SIP application information server through the Syncml protocol, the SIP protocol, the XML protocol, the XCAP protocol, or a proprietary protocol, and the request carries the terminal-specified contact identifier.

Step S16, after the SIP application information server receives the information synchronization request sent by the user information server, it retrieves the SIP application information corresponding to the contact identifier specified by the terminal from the SIP application information database, and the SIP application information includes at least the contact The person's SIP address identifier may also include the contact's mailbox name and/or group information and/or status information, and the SIP application information server sends the retrieved SIP application information to the user information server.

Step S17, after the user information server receives the SIP application information returned by the SIP application information server, it is associated with the corresponding contact identifier and stored in the contact information corresponding to the terminal identifier, and then sent to the terminal through the Alert message in the Syncml protocol Notification of successful information synchronization.

Step S18, after the terminal receives the information synchronization success notification from the user information server, it sends a contact information synchronization request to the user information server, and the user information server forwards the SIP application information obtained from the SIP application server to the terminal, and sends it to the terminal phone The directory is stored in association with the corresponding contact identifier, so that the terminal's local phonebook information is synchronized with the terminal's corresponding contact information in the user information server.
