Embodiment

Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope of protection of the invention.

As stated in the Background Art, though pure radio network or pure cellular network all have its limitation separately when mobile multi-media broadcasting service is provided, two kinds of network technologies have certain complementarity.Two networks are carried out effective fusion, can make the network after the fusion both can more effectively utilize network advantages separately, optimize and use Internet resources, can provide abundanter mobile multi-media service again.The following technical scheme that the embodiment of the invention provides is to address the above problem.

As shown in Figure 1, for a kind of in the embodiments of the invention merged the method that cellular network and radio network provide the MBMS business, be applied to comprise in the system of at least one terminal equipment and a fusion MCE, wherein, merge the switching of MCE control terminal between multiple cellular network and radio network, this method specifically may further comprise the steps:

Step S101, merge MCE and receive the current notification message that belongs to the QoS deterioration of the terminal equipment that the pairing access device of the terminal equipment that carries out the MBMS business in a kind of cellular network sends.

Wherein, the notification message of QoS deterioration specifically produces in the following manner:

Access device is by periodically detecting the QoS state information of obtaining terminal equipment;

When access device judged that the QoS state information of current terminal equipment is lower than default QoS threshold value, access device was to merging the notification message that MCE sends the QoS deterioration of terminal equipment.

Step S102, merge the information that MCE obtains the alternative network that terminal equipment can support.

In concrete application scenarios, this step specifically comprises following handling process:

Merge MCE and obtain the present Radio Resource state information of each alternative network that current terminal equipment may insert to the UNE information server;

Merge MCE and determine the alternative network set that terminal equipment may insert according to the Radio Resource state information;

Merge MCE to current access device transmitting capacity query requests, carry out capability query to terminal equipment by access device;

Merge MCE and receive the alternative network that terminal equipment that access device returns can be supported, determine the information of the alternative network that terminal equipment can be supported.

And after this step was finished, merging MCE can also gather the QoS information that pairing access device obtains each alternative network that terminal equipment can reach by each alternative network.

When comprising the information of radio network in the information of the alternative network that terminal equipment can be supported, execution in step S103;

When not comprising the information of radio network in the information of the alternative network that terminal equipment can be supported, execution in step S106.

Step S103, merge MCE judge the current MBMS business of carrying out of terminal equipment whether with current radio network content synchronization.

If execution in step S104 synchronously;

If asynchronous, execution in step S106.

Step S104, fusion MCE judge whether the state of terminal equipment meets the condition of carrying out the network switching to radio network.

If meet, execution in step S105;

If do not meet, execution in step S106.

Step S105, fusion MCE control terminal switch to radio network and carry out the MBMS business.

In the process of carrying out this step, on the one hand, merge the downstream service flow of MCE by the MBMS business of the channel support terminal equipment of radio network;

On the other hand, merge related control data stream and the uplink service stream that MCE still keeps the original MBMS business of terminal equipment.

Step S106, in the information of the alternative network that terminal equipment can be supported, select a kind of alternative network to carry out network to switch.

The processing procedure of this step specifically comprises:

Merge MCE and judge whether the state of current terminal equipment meets other alternative network that can support to current this terminal equipment and carry out the condition that network switches;

If meet, merge the MCE control terminal and switch to a kind of other alternative network that current terminal equipment can support and carry out the MBMS business.

If do not meet, merge MCE and abandon terminal equipment is carried out the network switching, or carry out the processing that other improve the communications status of this terminal equipment.

Need further be pointed out that, in above-mentioned step S105 and step S106, merge MCE and judge that whether the state of current terminal equipment meets the processing procedure that other alternative network that can support to radio network and/or current terminal equipment are carried out the condition that network switches, and specifically comprises following two kinds of situations:

Situation one, fusion MCE judge whether the QoS information of other alternative network that radio network and/or current terminal equipment can be supported reaches default switching threshold, when if QoS information reaches default switching threshold, merge MCE and determine that the state of current terminal equipment meets other alternative network that can support to radio network and/or current terminal equipment and carries out the condition that network switches.

Situation two, MCE sends the access capability query requests from other alternative network that radio network and/or current terminal equipment can support to access device that merges, and receive other alternative network that access device can support at radio network and/or current terminal equipment QoS information return Query Result, merge MCE and determine that according to Query Result the state of current terminal equipment meets other alternative network that can support to the pairing radio network of Query Result and/or current terminal equipment and carries out the condition that network switches.

Need be pointed out that further that for above-mentioned situation two, the Query Result that fusion MCE reception access device returns specifically can be divided into following dual mode:

Mode one, fusion MCE judge whether QoS information reaches default switching threshold

In this kind mode, after merging MCE transmission access capability query requests, all access devices that receive the access capability query requests all return to self current QoS information that can offer this terminal equipment MBMS business and merge MCE, judge by merging MCE whether the current QoS information that can offer this terminal equipment MBMS business of various alternative network that receives reaches corresponding switching threshold, and when reaching, determine whether the respective alternative network meets the condition that network switches.

In this mode, as long as each access device receives the access capability query requests, promptly carry out the current corresponding QoS feedback information that can offer this terminal equipment MBMS business, carry out no longer separately and handle, all judgement process unifications realize by merging MCE.

Further, owing to merge the current QoS information that can offer this terminal equipment MBMS business that MCE has obtained whole access device feedbacks, so, merge MCE and can consider respectively to merge the current QoS information state that can offer this terminal equipment MBMS business in the heterogeneous network comprehensively, and make corresponding judgment, wherein, if the QoS information of all-network does not all reach switching threshold, so, merge MCE and can determine whether that also needs selection network carries out network and switches according to the QoS information state of current each network, even without the alternative network that reaches switching threshold, also the service resources that may exist one or more network to provide is better than current network, under these circumstances, merge the switching that MCE can comprehensively judge whether to merge heterogeneous network.

For example: the resource that current network is being used is 40Mb/s, switching threshold is that resource reaches 60Mb/s, but the current alternative network of maximum resources that provides also can only provide 50Mb/s, so, merge MCE and may will consider to carry out the network switching, though because do not reach the switching threshold of 60Mb/s, the resource of 50Mb/s also will obviously be better than the stock number of current 40Mb/s, if system can tolerate resource and realize that such part promotes that it still is feasible implementing corresponding network switching.

It is to be noted; in concrete application scenarios; the above-mentioned processing of judging whether QoS information reaches default switching threshold can independently realize by merging MCE; also can be that MCE and other policy control functions entity are collaborative to be handled by merging; based on the above-mentioned technological thought of the present invention, the variation of specific implementation main body does not influence protection scope of the present invention.

Mode two, access device only feed back the QoS information of the switching threshold that reaches default

In this kind mode, each access device is after receiving the access capability query requests that merges the MCE transmission, judge at first whether the current QoS information that can offer this terminal equipment MBMS business reaches corresponding switching threshold, only when reaching, just feed back corresponding QoS information to merging MCE, therefore, merge all QoS information that MCE receives and all reach switching threshold, promptly all pairing networks of access device that fed back QoS information all meet the condition that network switches.

In this mode, each access device is after receiving the access capability query requests, at first need to carry out currently can offer the judgement whether this terminal equipment MBMS QoS of survice information reaches switching threshold, and the QoS information that will reach switching threshold is fed back, so no longer need to merge MCE and carry out judgment processing, and, for the QoS information that does not reach switching threshold, corresponding access device will no longer feed back, thereby save the mutual expense of the control information in the network.

In UNE with radio network and other alternative network, when terminal equipment need carry out the network switching, judgment mechanism based on UNE and content synchronization, the network of realizing cellular network and radio network switches, for terminal equipment continues to provide the MBMS business, thereby give full play to the advantage of radio network, can optimize the Radio Resource that uses UNE, improve the wireless network resource utilance.

The technical scheme that is proposed in order more clearly to describe the embodiment of the invention does further to elaborate below in conjunction with concrete application scenarios.

At first it is to be noted, in embodiments of the present invention, cellular network and radio network merge on content network and access device, the Data-carrying net is based on the all-IP net, and support various functions and multimode business in the UNE by corresponding functional modules based on each functional entity in each heterogeneous network that merges, this is the precondition that realizes the technical scheme that the embodiment of the invention proposed.
