Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a PoC-based information presentation method and apparatus. BACKGROUND OF THE INVENTION In recent years, with the development of mobile phone technology and the continuous growth of service providers, many new services have emerged, including PoC services.

PoC is the abbreviation of Push to Talk over Cellular. It refers to the half-duplex voice service implemented by VoIP technology based on the mobile cellular network packet domain, and can support one-to-one session and group session. The PoC conversation group can be divided into a preset group, a temporary group, and a chat group, which can be managed by the operator or the enterprise administrator or can be defined by the user. In addition to having a session function, PoC services can also provide users with automatic answering, manual answering, do not disturb, callback requests and other functions. Currently, the PoC presence information includes only the status information presented: online, offline, and do not disturb. The user device logs in to the network through the PoC. During the login process, the PoC sends a message to the server on the network, and the message carries a field with status information. Through this field, the server issues the status of the user to the contact on the user's PoC. , such as online, do not disturb, when the user leaves the network, the server publishes the user's offline status to the contact on the user's PoC. In the above login process, since the PoC only carries a message embodying three states, the content of the message delivered to the server is small, thereby reducing the amount of information acquired by the PoC user's contacts. SUMMARY OF THE INVENTION An object of the present invention is to provide a PoC-based information presentation method and apparatus, which solves the problem that PoC technology carries less information when presenting information. In order to achieve the above object, the present invention provides a PoC-based information presentation method, including: receiving a PoC status message of a PoC user; transmitting the acquired PoC status message to a PoC user associated with the PoC user through the PoC; User gets XML in PoC status message Data for each field in the document; associated PoC users present data. According to another aspect of the present invention, a PoC-based information presentation apparatus is provided, including: a receiving module, configured to receive a PoC status message of a PoC user, and a transmission module, configured to transmit the acquired PoC status message to the PoC through the PoC a PoC user associated with the PoC user; a parsing module, configured to acquire, by the associated PoC user, data corresponding to each field in the XML document in the PoC status message; and a display module, configured to present data through the associated PoC user. The present invention can enable the PoC service to support extended presentation information such as busy, leave, mute, stealth status and avatar, personalized signature, city, weather forecast, etc., so that the user can have a more comprehensive body-risk when using the PoC service. For example, the user can get a clearer picture of the friend before going online to prepare a call with the friend.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A PoC-based information presentation method will be described below with reference to the accompanying drawings. Refer to the PoC client and network side software function framework diagram shown in Figure 1. The client software includes four functional modules: client function PoC client module, XML document management client XDMC module, Presence source module and Watcher module. among them, The PoC client module is located on the mobile terminal and is used to access PoC services. The PoC client module implementation functions include: implementing session establishment, participation, and release; registering with the Session Initialization Protocol/IP (Internet Protocol) Core; authenticating the user to the SIP/IP Core; Collect and encode to generate and send Talk Burst; Receive Talk Burst, and generate speech by decoding; Support the control process of the voice and media negotiation; If it is a server-initiated session, support the user-level adaptation process.

The XML Document Management Client (XDMC) module enables the creation, modification, retrieval, and deletion of XML documents stored in XDMS. The XML document management client is able to subscribe to XML documents stored in XDMS and will be notified when the XML document changes. The Presence Source information publishing module is used to publish Presence publishing information of the user's settings.

The Watcher monitor module is used to complete the Presence publishing information of the subscribed contact list. The network side software should include seven functional modules: SIP Proxy SIP proxy/SIP Registrar SIP registration function module, used for user login registration, PoC XDMS function module is used for management group operation, when the PoC document stored in the network changes, notify it The subscribed user, the PoC Server function module is used to control the session, the Aggregation Proxy module is used to authenticate the user's access rights, the DB database management module is used to manage the database, and the Presence Server function module, Shared XDMS module. In addition, the Presence Server function module is used to receive, store, and distribute Presence information of the PoC client function module. The user's Presence information may be published by the Presence Source module in the user equipment UE, or may be published by the SIP Proxy/SIP Registrar module of the SIP Proxy/SIP registration on the server side. The Presence publishing information of the associated buddy user can be subscribed and obtained by the Watcher module in the UE. The Presence Sever module also retrieves XML document data from the Shared XDMS module and the Presence XDMS module, and subscribes to changes to the XML document.

The XML document saved by the Shared XDMS module is a list of contacts' URIs, which can be PoC,

Businesses such as Presence share. Support for directory document capabilities for display of contact lists. The Shared XDMS module can support subscription and update notifications for shared XML documents stored there. The information presentation method of the present invention can be performed based on the above-described functional framework. Referring to the flowchart of the first embodiment shown in FIG. 2, the method generally includes the following steps: S100: a Presence Source module in a PoC user issues a PoC ^1 state message indicating a large state change to a server; After logging in, once the status information changes, the Presence Source module first sends a PoC status message indicating the status change to the server;

S102: The Presence Sever module of the server receives the PoC status message; S104: The Presence Sever module of the server queries the Shared based on the PoC status message

The friend associated with the Poc user in the XDMS module sends a message corresponding to the status change to the friend of the PoC user. The notification message contains an XML document for storing the presentation information of the client of the PoC user. The server may also directly send the PoC status message to the PoC user's friend, that is, the PoC user's associated PoC user, in ^! The state message has an XML document, including the presentation information of the PoC user. Network Status Messages Of course, the PoC network status message may include status information such as busy, leave, mute, stealth presentation status, and personality signature, or may be user-uploaded avatar information, or may be user's geographic location and weather information. . Next, the processing method of the change of these information in the present invention will be described one by one with reference to the drawings. It should be noted that the above user information is not limited to the information we mentioned. The specific process of issuing a personalized signature and network status of a PoC user is described in the following. The flowchart of the second embodiment shown in FIG. 3 includes the following steps:

S200: The PoC user starts the PoC client and successfully logs in. S202: After the PoC user manually sets the busy/away state through the Poc client module, execute

S204: The PoC user issues a PUBLISH poc-setting message corresponding to the busy/away state through the presence source module; and then proceeds to step S224; S206: After the PoC client module determines that the busy and leaving state is reached, the process proceeds to S208: the PoC client module automatically sets a PUBLISH poc-setting message corresponding to the busy and leaving state, and then proceeds to step S224; when the PoC user, that is, the PoC client is running in the background When the PoC client has no resources to create a session, the PoC client will automatically publish the busy presentation state. After the PoC client is idle for a period of time or when the mobile phone is sleeping, the PoC client will automatically leave the presentation state.

S210: After the PoC client sets the state to the mute state by using the PoC client module, the process proceeds to S212: the PUBLISH poc-setting message corresponding to the mute state is issued by the Presence Source module, and then the step S420 is performed. S214: The PoC user sets the state through the PoC client module. After the invisible state, execute S216:

The Presence Source module issues a PUBLISH poc-setting message corresponding to the stealth state, and then proceeds to step S224;

S222: The PoC user tampers with the PUBLISH poc-setting message corresponding to the signature by using the PoC client module, and then proceeds to step S224. After step S206 and step S208, the method further includes:

S218: When the PoC client module determines that the busy and leaving status conditions are not met, step S220 is performed: the Presence Source module automatically issues the busy/de-settled state, and then proceeds to step S224.

S224: The Presence Sever module in the server notifies its PoC friend to update the updated status information. The Watch module in the PoC buddy, ie, the associated user, monitors the presence status and presents the corresponding text or picture after the status message changes. The status information of the PoC user published to the server is a message. In this XML message corresponding to the PUBLISH PoC-setting message, the network status field is enhanced, for example, an extra-presence-setting field is added, and the field is added. Contains two fields: status: rendering status, description: signature. The data corresponding to the Status field is "Busy", "Away", "Mute", or "Invisible". The notification message sent to other users is a message, which also contains the network status field in the XML document corresponding to the NOTIFY presence message, such as the booster port. The extra-presence field, which in turn contains two fields: status: presentation state, description: signature. The data corresponding to the Status field is "Busy", "Leave", or "Mute". With these updated status data, the user can display the corresponding text and/or picture of the status data to display the corresponding status and signature. For new PoC clients that do not support busy, leave, mute, stealth, or personality signatures, these new fields can be ignored. In the above process, if the PoC user turns on the silent mode, regardless of whether the current scene mode of the mobile phone is silent mode, all callback requests and incoming calls do not play ringtones. If the setting status of the PoC user is invisible, the PoC friend will not receive the online notification, and the corresponding presentation status is still offline. If the PoC user logs in and the status is invisible, the friend will receive the offline notification, and the corresponding presentation will be performed. The status is offline. Stealth status does not affect users accepting callback requests and incoming calls. The present invention can also implement busy, leave, mute, stealth state and personalized signature by adding event types, that is, re-creating a new message, and the corresponding XML document contains a presence status field and a personalized signature field. Image information When the PoC user updates the avatar information, the server posts the updated avatar information to the associated PoC user. After the PoC user successfully logs in, the static image of BMP, JPG, JPEG, PNG, etc. can be selected and uploaded to the HTTP PUT method. The server then publishes the PoC user information uploaded by the avatar to the server. After the server receives the complete avatar data, it is saved in the corresponding folder of the PoC user. The file name is a fixed value, for example: The file name is portrait, and the CRC value of the new avatar is calculated and saved in the folder. Also a fixed value, for example: portrait-crc. A NOTIFY message containing avatar information is then sent to the PoC friend of the PoC user. The specific process can be seen in Figure 4, the process is as follows:

S300: The PoC user starts the PoC client and logs in successfully. S302: PoC User The PoC Client module sets an avatar, uploads it to the PoC xdms module in the server through HTTP PUT, and receives the PoC xdms module feedback message.

S304: The server notifies its PoC friend to update the presentation. After receiving the complete avatar data, the PoC xdms module of the server first queries the PoC friend of the PoC user on the Shared XDMS module, and then sends a field NOTIFY message containing the indication image through the Presence Server module. In this message, the fields are also stored in the XML document.

S306: After the PoC friend finds that the presence information is changed by the Watch module, the PoC Client module compares the image indication data CRC data in the field of the received indication image with the locally saved CRC data, and the process proceeds to step S308. If you do the same, you can continue to use the locally stored avatar data without performing any operations. In the XML document corresponding to the NOTIFY presence message, the booster port indicates the portrait field of the image, and the field further contains two fields, each field having corresponding image indication data, respectively: crc field: avatar CRC data, url field: Avatar URL. The url is the HTTP address of the PoC user avatar. The PoC client module in the PoC friend determines whether the avatar CRC is the same as the locally saved CRC, that is, whether the local storage is the latest one. If not, the HTTP GET method is used to download the avatar data according to the URL address in the field, and then save. Go to the local and display.

S308: The PoC Client module in the PoC friend downloads new avatar data, overwrites the original avatar data, and saves it to the local, and updates the interface display. For PoC clients that do not support avatars, these new fields can be ignored when processing PoC user information. The invention can also realize the presentation of the avatar information by adding the event type, that is, re-creating a new message, and the corresponding XML document contains the CRC field and the URL field. Of course, these avatar data are image data of the user, and may also be image data of various scenery. The specific process of the geographic location is shown in Figure 5. When the PoC user logs in, the server searches for the geographic location of the PoC user according to the IP address of the PoC client or the location address of the base station to which the PoC client is located, and obtains the city where the PoC client is located and the local area according to the geographic location. The weather forecast, and then send a NOTIFY message containing information about the city and the weather to its friends. The process is as follows:

S400: Start the PoC client and log in successfully. S402: The SIP Proxy/SIP Registrar module of the server collects the geographical location of the user. The SIP Proxy/SIP Registrar in the server obtains the corresponding geographical location data through the IP address information of the PoC user or the location information of the base station, and according to the geographical location data, the corresponding weather data is obtained. S404: The server issues a message to its friend through the Presence Server module and notifies the update presentation. The server adds an attribution location field to the XML document corresponding to the NOTIFY presence message posted to the friend through the Presence Server module. The field contains two fields: city: city, weather: weather. The range of city is limited to prefecture-level cities. Weather can include temperature, wind direction, wind direction, sunny and rainy weather.

After the Watch module of the PoC client finds that the status information of the friend changes, the PoC Client module identifies the field as a home field. If the data corresponding to the field is identified as the geographic location data, the corresponding address location text information is displayed, such as Beijing; if the data is identified as weather data, the corresponding text and/or picture, such as light rain, sunny, etc., is displayed. For PoC clients that do not support geolocation, these new fields can be ignored. Of course, step

The Ml S402 can also perform operations to update the geographic location and weather by the associated PoC client. The present invention can also realize the geographic location by adding a new event type, that is, re-creating a new message, and the corresponding XML document contains a city field and a weather field. In each of the above embodiments, the PoC user transmits a status message to the server, and the server issues the latest status to the associated PoC user through the status message. In this process, the PoC user can transmit a status message to the server, and the status message is forwarded by the server. For each associated PoC user, that is, the same message is sent; or, the PoC user sends user information indicating the status change to the server, where the user information may be a message containing the first XML document, For storing various information such as "busy" information, "away" information, "mute" information, "invisible" information, and personalized signature information of the client; the server sends and changes to the associated user based on the user information; Corresponding notification message, the notification message, the second XML document is used to store the client's "busy" information, "away" information, a message in the "mute" message, and status message information such as personalized signature information; Send with a different message. Preferably, the status message sent by each PoC user can be passed by the base station through the message short message. The Unstructured Supplementary Services Data (USSD) receives the PoC status message of the PoC user, and also receives the PoC status message of the PoC user by using the SIP protocol, and passes the obtained PoC status message through the month. The server transmits to the PoC user associated with the PoC user. The method of the present invention has been described in detail above.
