Description

Method for transmitting service information, network function entity and user equipment This application claims to be submitted to the Chinese Patent Office on July 27, 2007, the application number is 200710137634.1, and the invention name is "method of sending business information, network function entity and user equipment" Priority of Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for transmitting service information, a network function entity, and a user equipment. Background technique

In the IP Multimedia Subsystem (IMS) service, different Public Service Identity (PSI) is provided to represent different services. User Equipment (UE) needs to obtain these PSIs in advance in order to use the corresponding services in IMS.

For example, when the IMS service is a voice conference service, the service provider provides a URI of the voice conference service, which is called a conference factory URI, and belongs to the PSI. For users who need to hold a conference, the conference factory URI must be configured on the UE to use the conference service. In addition, different users need different service attributes, and the user needs to be configured on the UE to use normally. For example, in the group management service, each user has a unique global resource list URI (Resource List URI). This resource list URI also belongs to the PSI. The user needs to configure its own resource list URI on the UE to use. The business.

In the prior art, the PSI is configured on the UE, and the PSI is distributed to the user when the user opens the account, and is manually configured on the UE by the user. Specifically:

Step 101: The service provider issues the PSI to the user;

Step 102: The UE provides a configuration interface, and the user inputs the PSI acquired in advance through the configuration interface of the UE.

Step 103: Save the PSI on the UE device to avoid inputting every time it is used.

In the process of creating the present invention, the inventors found that the above-mentioned technology for configuring PSI on the UE is At least the following technical issues exist:

1) For service providers, there is a lack of flexibility in deployment. After the PSI is announced by the service provider, all the users need to be notified when the PSI is changed. Because of this long change cycle, the service provider needs to support both the old and new PSI, increase the cycle and cost of deployment changes, and cause difficulties for users. ;

2) For users, the ease of use is poor. When the user re-installs the UE or uses it on a different terminal device, the information needs to be manually re-configured, and the user needs to obtain the PSI in other ways in advance, which is inconvenient for the user who uses the service. Summary of the invention

The embodiments of the present invention provide a method for transmitting service information, a network function entity, and a user equipment, which can improve service configuration flexibility and ease of use.

A method for sending service information according to an embodiment of the present invention includes:

Embodiment 1

Referring to FIG. 1 , a method for sending service information according to an embodiment of the present invention includes the following steps: Step 101: Receive a registration request initiated by a user equipment;

In this embodiment, the user equipment is a Session Initiation Protocol (SIP) terminal. When a SIP terminal accesses an IMS system, it generally needs to be registered in the IMS system and authenticated before the corresponding service can be used. Therefore, in this embodiment, the registration process is performed, and the user equipment initiates a registration request to the network side, and the network side receives the request.

In this embodiment, the registration process can be implemented by SIP signaling interaction.

Step 102: Determine whether the user equipment registration is successful.

After receiving the registration request, the network side accepts the registration operation of the user equipment.

After the registration is completed, it is determined whether the user equipment registration is successful. The result of the judgment is used to decide whether or not to perform the following step 103.

Step 103: After determining that the registration is successful, sending corresponding service information to the user equipment;

When it is determined that the registration is successful, the network side joins the service information in the BODY part of the 200 OK response of the user equipment registration and login, for example, the service identifier corresponding to the user equipment, where the service identifier may be a public service identifier and/or Or personal public service logo. The 200 OK response carrying the service identifier is then returned to the user equipment.

At the same time, the BODY part of the 200 OK response may also carry a service description of the service identifier, to inform the user equipment that the service identifier is carried in the 200 OK response, and the service identifier may be used for configuration. The usage statement may be an identifier that the user equipment can recognize.

For more specific explanation, let's take an example of carrying a service identifier in a 200 OK response: SIP/2.0 200 OK

</config-info>

The BODY part of the 200 OK response may be in the format of an Extensible Markup Language (XML) document, where "Content-Type: application/config-info+xml" indicates that the xml document format is used, and It is used to carry the service identifier and its usage description, and tell the user that the device is used to configure the service identifier. This example is only for explaining how to carry the service information in the 200 OK response, and does not define the message format content, but can be understood by those skilled in the art. There are many ways to carry the service information in response to the 200 OK response, and in the present invention, the service information can be carried by the 200 OK response, and can be carried by the new message, and will not be described here.

Step 104: Receive service information corresponding to the user equipment from the network side, and if it is a service identifier, perform configuration.

After the user equipment receives the 200 OK response that is sent by the network side and carries the service identifier and its usage description, the service identifier is obtained from the 200 OK response according to the usage description. Identify and configure. The method for configuring the service identifier may include, but is not limited to, one of the following methods:

I. Cache the service identifier in a memory, so as to use the network side service according to the service identifier; or

II. The service identifier is stored locally, and may be in the form of a database or a file, so that the service on the network side is used according to the service identifier. If it is saved locally, it can be encrypted if necessary.

The foregoing embodiment is also used to obtain the required service identifier by the time when the user equipment registers with the network side, and more specifically, the service identifier is carried in the registration success response message 200 OK to obtain the service identifier, except that the service provider deploys the public service identifier. In addition to flexibility, it is more efficient because it does not increase signaling and processes;

At the same time, since the user can not participate in the operation, the process is invisible to the user, the user is easy to use, the user experience is improved, the high cost of the manual operation of the user is avoided, the mistakes that are easily caused by the manual operation are avoided, and the user is used. Satisfaction

Furthermore, the application of the present embodiment can improve the security of information. In the prior art, because the PSI is manually configured by the user, the PSI is not handled privately by the service provider to deliver the PSI to the user. However, for the user who has the privacy requirement, the service provider passes the account when the user opens the account. In the process of informing users who request privacy, such as paper, e-mail, etc., it is difficult to ensure that these PSIs that are private are not obtained by others. In the present embodiment, the SIP protocol with high information security is used to transmit information, satisfying the privacy requirements of customers, and avoiding leaks.

In addition, in step 103, the service description of the service identifier may not be sent, but the network side and the user equipment perform the pre-negotiation/protocol. After receiving the service identifier, the user equipment is configured according to the negotiation/protocol.

Embodiment 2
