Description

A method for customizing network push service

technical field

The invention relates to network services, in particular to a method for customizing network push services.

Background technique

The network push service, also called PUSH service, is a service mode in which the network actively pushes content to users at regular intervals (or in real time). Many current or future services require the ability of external network entities to actively push data to users.

According to the type of delivered content, there are two ways: one is to send the content directly to the user through a single message; the other requires a series of messages, such as movie clips. The content push of a single message does not require a specific IP connection, and the content push of multiple messages requires a specific IP connection between the application server and the user. For a specific connection situation, the user IP address is required, so that the application server can transmit PUSH content through IP. When the application server initiates a service, it requests a connection to the user. When the service ends, the server or the user releases the connection. The connection is assigned an IP address. For the connectionless case, the user IP address is not necessarily required.

There are many ways to identify the user address of the PUSH service, and each address way is related to a specific network structure. Including: directly using the user's static IP address to send IP packets; using the SIP (SessionInitiation Protocol, initial session protocol) logo to initiate a SIP session connection, using the returned IP address to send content on the SIP bearer connection; the content is included in the SIP notification message body In, send to the user identified by SIP; query the user domain name to DNS (Domain Name Server domain name server), and send the content with the returned IP address; the user address in the SIP Invite message body is such as MSISDN (MobileStation ISDN, mobile station ISDN number), After the bearer connection is established, use the returned IP address to send content; for connectionless transmission, the application server sends the entire PUSH content and user ID to the delivery network, and the delivery network directly uses the user ID to send messages to the user; use the user's short message address such as MSISDN, Send PUSH content to the short message center.

For mobile GPRS (General Packet Radio Service, General Packet Radio Service) packet network, 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) currently proposes a variety of PUSH methods, including: for a user identification (MSISDN number or IP Address) network request PDP context (Packet Data Protocol context, data packet protocol context) activation; trigger PDP context activation through DNS query; short message PUSH; PUSH through permanent online dynamic address and short message; SIP-based PUSH; use HTTP as a PUSH proxy structure for transport protocol.

Since different PUSH methods have different implementation schemes, and there are various wireless access methods, including WLAN (Wireless Local Area Network, wireless local network) and other broadband wireless access in addition to GPRS, users will use different access methods at different times. Way. The specific application server does not currently have any regulations on what delivery network and method a user uses to push content. Generally, the application server adopts the default PUSH method for specific content, and cannot customize the PUSH method for different user capabilities and personal preferences. Among them, the user capability characteristics include which access methods are supported, whether it supports SIP, whether it has a static IP address, whether it supports GPRS network side activation, whether it is permanently online, etc.; user personal preferences include supporting multiple access methods and multiple PUSH methods at the same time Which one is preferred at different times, and different options can be selected at different time periods. When a certain PUSH method fails, the application server automatically adopts other PUSH methods. Since the existing network cannot implement the above functions, the PUSH service cannot be implemented well, which not only reduces service efficiency, but also greatly reduces user service experience.

Contents of the invention

In view of the deficiencies in the prior art above, the present invention provides a method for customizing network push services, which can realize the customization of network push services for different users.

The network pushes the PUSH business customization method of the present invention, comprises the following steps:

A) establish a user database, store user information and PUSH service customization information corresponding to each user in the user database;

B) When there is business content in the application server that needs to be pushed to the user, the application server queries the user database, and the user database returns the corresponding PUSH method to the application server according to the stored user current information and the user's PUSH service customization information; The PUSH method includes one of the following methods or any combination of them:

General packet radio service GPRS network side activation mode;

Initial session protocol SIP PUSH;

Short message PUSH;

Wireless Application Protocol WAP PUSH;

Wireless local network WLAN PUSH;

C) The application server uses the PUSH method returned by the user database to push the service content to the user through the transmission network.

According to the above method of the present invention, the user database can be an independent network entity, which is connected with the application server through an interface protocol.

The user database can also be set in the application server, which is a part of the application server.

The returned PUSH method is a specific PUSH method or a priority-ordered PUSH method list.

If the list of PUSH methods is returned, the application server executes the PUSH method with high priority first, and then executes the PUSH method with lower priority when the execution of the PUSH method with high priority fails.

According to the method of the present invention, it also includes the step of the user accessing the user database to modify user static information or user PUSH service customization information. The user static information includes the PUSH mode and user identification supported by the user terminal.

The user identification is: mobile station ISDN number, International Mobile Subscriber Identification Code, SIP URI identification, static IP address or EMAIL address.

According to the method of the present invention, it also includes the step of requesting the application server to the user terminal to dynamically report the user's current information to the user database, and the user's current information at least includes: the user's access information and location information.

The dynamic reporting of the user's current information is realized by combining with the user status service Present service or other application layer protocols.

The user's PUSH service customization information in the method of the present invention includes: using different PUSH methods in different time periods, defining the priority levels of various PUSH methods, and the corresponding relationship between various PUSH methods and user access networks.

The method of the invention can enable users, operators or service providers to customize the PUSH service as required, so that the PUSH service can be realized more flexibly and more optimally.

Description of drawings

Fig. 1 is a customized PUSH service network framework of the present invention.

Detailed ways

The invention optimizes the realization of PUSH service, so that operators, service providers and users can customize PUSH service according to different user terminal capability characteristics, different access networks, user current status information and user personal preferences.

In order to better realize the PUSH service, the present invention adopts the network framework as shown in FIG. 1 . The PUSH service framework in the prior art includes a user terminal, a transmission network and a PUSH application server; the customized PUSH service framework of the present invention adds a user database on the basis of the prior art framework, which is used to store user terminal information, user or operator and information customized by service providers, current user information, etc., which may specifically include the following:

(1) PUSH methods supported by the user terminal, such as GPRS network side activation, SIP PUSH, short message PUSH, WAP (Wireless Application Protocol, wireless application protocol) PUSH, WLAN PUSH, etc. and any combination of the various methods ;User identification includes but not limited to: MSISDN number, IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) number, SIP URI (Unified Resource Identifier, Uniform Resource Identifier) logo, static IP address, EMAIL address, etc., this part The information can be statically configured by the operator, and can be modified according to the user's requirements, and the user can also modify it by himself in some way.

(2) Customization information of the PUSH method, including but not limited to: use different PUSH methods at different time periods; define the priority level of the PUSH method, and use a lower priority PUSH method when the high-priority PUSH method fails; The user's current information, such as which access network and whether the user is GPRS online, determines the corresponding PUSH method.

(3) The current information of the user, including whether the user is reachable, GPRS online status, SIP registration status, whether to access WLAN, user location information, etc. These information need to be updated dynamically, which can be reported actively by the user terminal, or reported by the network device through a certain method . The provision of the user's current information can be combined with the Presence service or realized in other ways. Such as positioning service LCS (LocationService).

The PUSH service customization process of the present invention is as follows:

(1) The operator or service provider configures user static information in the user database and customizes PUSH rules; the user accesses the user database in a certain way, customizes PUSH rules or modifies user static information.

(2) If the application server needs the user's current information, the application server can request the user terminal or network entity to dynamically report its current information to the user database through the Presenc service or other application layer protocols (such as location service LCS, Location Service), such as various Access information and location information, etc.

(3) When the application server has content that needs to be pushed to the user, query the user database, the user database selects the corresponding PUSH method according to the user's current information and the customized information of the PUSH service, and returns information to the application server, which can be a PUSH method, or A list of PUSH methods in order of priority.

(4) The application server pushes the content to the user through the corresponding transmission network through the PUSH method returned by the user database. When the list of PUSH methods with priority order is returned, the PUSH method with high priority is executed first, and if the PUSH method with high priority is unsuccessful, it is sent through the PUSH method with lower priority.

During specific implementation, the user database may be an independent network entity, or be set in the application server and belong to a part of the application server. If the user database is an independent network entity, it can be connected to the application server through various interface protocols in the prior art.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
