Description

A method and system for starting a PoC service

technical field

The present invention relates to radio communication technology, in particular to a method and system for starting a PoC service.

Background technique

The Push-to-Talk Over Cellular ("PoC") service defines a half-duplex packet voice (Voice over IP, "VoIP") system suitable for mobile devices. Through this service, users A PoC session can be initiated to a single user or a group. The general process is that the caller first submits a session request to the server, and the server then sends a session request to a single user or all members of the group, and the called party joins the PoC session by replying.

The structure diagram in the PoC standard formulated by the Open Mobile Alliance (OMA) is shown in FIG. Presence) processing is implemented through reference points PoC-2 and PRS-2.

The communication between PoC Server (PoC Server) and Presence Server (Presence Server) is completed by using Session Initiation Protocol (SIP: Session Initiation Protocol) and SIP specific event notification mechanism [RFC3261], [RFC3265].

The relevant functions of the PoC server are as follows:

1) As a status information source (Presence Source):

11) Mapping the dynamic PoC state information into user state information, which describes the availability of the user for communication using the PoC service.

12) Release PoC-related status information to the status service on behalf of the PoC client (PoC Client).

2) As an observer:

Requests or obtains state information from a state server to convert that information into information meaningful to the session's initiation policy enforcement.

In the user equipment (UE: User Equipment), the watcher (Watcher) associated with the PoC client can use the status service engine to determine the PoC status of other PoC clients.

The presence source (Presence Source) can publish status information to the PoC server, and the relevant status information includes:

1) Session availability: indicates whether the user is currently able to answer a new incoming call request.

2) Willingness to receive a session: indicates whether the PoC user is currently willing to receive the current incoming call request.

Status sources providing status information are routed to the status server via interface reference points PRS-1 and PRS-3.

The PoC server can publish status information to the status server based on the status of the PoC client in the PoC session.

The PoC server can use the function of the state service engine to obtain the state information of any client by subscribing to the state information of the PoC client.

The communication between the state server and the PoC server is completed by signaling SIP/IP, and the routing is realized through the interface reference point PRS-3.

When the user equipment at the calling end initiates a session request to the PoC server, the PoC server can obtain the group members from the document management server (XDMS: XML Document Management Server), and then forward the call request to each other member in the group (by Calling client), after the called client answers (it may be a manual answer, or it may be an automatic answer) to join the session.

At present, there is already an application system that integrates PoC services and mobile services on a mobile terminal (such as a mobile phone). When the PoC application service in the mobile terminal is activated, the PoC service can be used after registration is completed, but there is a situation where the user Only turn on the mobile phone without starting the PoC service. If other PoC users want to talk to the PoC user who has not logged in to the PoC service, the call cannot be established, and the called user will not receive any notification. The current solution is: , the terminal needs to continuously re-register with the server to tell the server the location information of the terminal, so it occupies a relatively large network resource, and the status information is not effectively used, and the application function of the system cannot be fully realized.

Contents of the invention

The purpose of the present invention is to provide a kind of PoC service start method and system that can start PoC service in time, by obtaining whether the user who does not open PoC service opens the mobile terminal, then sends the notice of starting PoC service to the terminal, so that the received user can Start the PoC service and establish a PoC session.

Status information, when the PoC-related status information of the called party is unavailable, the PoC server sends a session notification to the called party through the mobile terminal message system, and the called party starts the PoC service accordingly according to the session notification.

The method comprises the steps of:

A. The PoC server receives or actively initiates a session request;

B. The PoC server obtains the called PoC-related state information, and performs the following operations according to the called PoC-related state information:

B1. If the PoC-related state information of the called party is that the session is available and is willing to receive a new session, the PoC server initiates a PoC session request to the called party;

B2. If the called PoC-related state information is unavailable, the PoC server obtains the called mobile service-related state information, and performs the following operations according to the called mobile service-related state information:

B21. If the mobile service-related status information is available, the PoC server sends a session notification to the called party through the mobile terminal message system, and proceeds to step C as follows;

B22. If the mobile service-related status information is not available, return failure information and end the process;

C. After receiving the session notification, the called party starts the PoC service accordingly.

When the PoC server sends a session notification to the called party, the application is sent with a high priority.

The session notification sent by the PoC server includes the starting method after the user receives it;

The described startup mode is to start immediately by the user or after confirmation by the user.

The notification sent by the PoC server also includes session related information.

This PoC service activation system includes a PoC server, a status server and a mobile terminal integrating PoC services and mobile services. The PoC server obtains the service status of the mobile terminal through the status server, and is characterized in that it also includes a mobile terminal message system. The mobile terminal message system described above handles authentication and routing of session notifications. The service status of the mobile terminal includes PoC-related status information of the mobile terminal. When the PoC-related status information of the called party is unavailable, the PoC server passes the mobile terminal message The system sends a session notification to the called party, and the mobile message system receives the session notification sent by the PoC server and forwards it to the mobile terminal.

The service status of the mobile terminal includes PoC-related status information and mobile service-related status information of the mobile terminal.

The PoC server includes a corresponding message sending module, and the mobile terminal includes a corresponding message parsing module, wherein the message sending module completes the application for sending session notification authentication, sending the session notification, and Invite a corresponding session according to the status information of the service; the message parsing module receives the session notification, and completes the start of the PoC service according to the session notification or related configuration.

The message analysis module receives the flash message information of the message system of the mobile terminal, that is, it only displays the information without storing it.

The message parsing module is provided with a memory, and the memory is used for data buffering.

The mobile terminal message system is a short message system, and the short message system forwards the short message information of the session notification to the called party.

The mobile terminal messaging system is a mail system, and the mail system forwards the email of the session notification to the called party

The beneficial effects of the present invention are: in the present invention, when the called PoC-related status information is unavailable, the PoC server sends a session notification to the called party through the mobile terminal message system, and the called party starts the PoC service accordingly. When the PoC service in the terminal is turned on, the session notification can be obtained in time, and the call will not be missed, which makes up for the deficiency in the prior art that the call cannot be established without starting the PoC service, and can fully realize the application functions of the system; at the same time, the PoC terminal (i.e. the mobile terminal) can start the PoC service in time and properly without opening the PoC service, which can effectively save network resources compared with the prior art; the notification sent by the PoC server can also include session-related information, such as Initiator, topic of the conversation, group ID or participants of the current conversation, etc., so that even if the user cannot receive the PoC request during the busy process (such as making a phone call), he can receive the corresponding PoC request when he is idle (such as after the call is completed). Short messages or emails can be used to obtain session information in a timely manner, so as not to miss the PoC session, which further improves the practicability of the present invention.
