Fig. 3 illustrates the operating process according to portable terminal access to remote monitoring system of the present invention.
Below, with reference to the accompanying drawings 3, the operation of portable terminal access to remote monitoring system according to the present invention is described.
At first, at step S1, M-CU initiates professional application to Portal.At step S2, after receiving from the user of M-CU request, Portal carries MSISDN (parametric user's sign) and orders to ISMP and concern authentication.Then, at step S3, the relation of ordering of ISMP authentication MSISDN is returned the relation of ordering by the back to Portal.At step S4, after Portal received message from ISMP, Portal showed the control point tabulation that the user has the right to monitor to M-CU.At step S5, M-CU initiates the monitoring request according to the tabulation select target control point of being showed by Portal, control point to WAP GW, carries parameter service identification (SID), content identification (CID), stream media system address (PSS_URL) etc. in this request message.At step S6, WAP GW initiates the monitoring request according to finding stream media system (PSS) from the stream media system address in the request message of M-CU to it, carries parametric user's sign (MSISDN), SID, CID etc. in this request message.At step S7, after stream media system received this request, stream media system sent the request of charging according to the MSISDN, the SID that carry in the request, CID to ISMP.At step S8, after ISMP received this charging request, ISMP determined that according to SID, CID rate charges to the user, and co-current flow media system PSS returns charging message.At step S9, PSS carries the PSS-URL parameter and sends monitoring request return messages to WAP GW.At step S10, WAP GW carries the PSS-URL parameter and sends monitoring request return messages to M-CU.At step S11, after M-CU received return messages from WAP GW, M-CU carried MSISDN etc. and initiates video request to PSS.At step S11, after PSS received video request from M-CU, PSS initiated video request to 3G video access unit VAU.At step S12, after 3G video access unit received video request from PSS, 3G video access unit VAU carried out video request according to the parameter in the request message according to the operation flow of global eye definition in the global eyes side.Wherein, the process of the video that obtains asking according to global eye at the global eyes network side is known for those skilled in the art, therefore, does not repeat them here.At step S13, the video that 3G video access unit VAU will ask carry out encoding and decoding conversion and adaptive after transfer to PSS.At step S14, PSS receive from the encoding and decoding conversion of 3G video access unit VAU and adaptive after video data stream, and with transmission of streams of video data to M-CU, resolve and play by the terminal player among the M_CU.
In the above description, comprise Portal and ordered the step that concerns authentication to ISMP, and stream media system sends the request of charging to ISMP, ISMP determines the step that rate is chargeed to the user, but those skilled in the art are to be understood that, above-mentioned flow process only provides as example, and for the portable terminal access to remote monitoring system, above-mentioned charging step and other listed step are not must be necessary.
In addition, shown in the step S15 among Fig. 3, M_CU is undertaken can realizing the control of user terminal to front end cloud mirror alternately by interface and the VAU that formulates.For example, under the situation that the customer requirements The Cloud Terrace turns left, click in the customized application interface of 3G subscription on the M-CU/ terminal " turning left ", utilize this application related news to be transferred to 3G video access unit VAU " M-CU interface " by network then.3G video access unit VAU by global eyes CMS interface with the CMS of message transparent transmission to the global eyes network.CMS judges the position that will obtain the The Cloud Terrace place, and informs The Cloud Terrace by message.The Cloud Terrace turns left after receiving message, realizes the operation according to user's indication thus.
Though detailed description of the present invention is at example embodiment, to those skilled in the art, various modification and the replacement form of these embodiment all can be imagined.Therefore, all modification and replacement forms in the clear and definite scope of patent protection of the present invention of claims have been contained in the present invention.
