Background technology
In TD SDMA (TD-SCDMA) system, the Traffic Channel (MTCH) that transmits multi-media broadcasting service (MBMS) is disposed and is controlled by MBMS control channel (MCCH), and the configuration information of MCCH then is to be broadcasted by the system information of terminal persistent district.Terminal reads the system message of persistent district under idle condition, and the MCCH configuration store of inciting somebody to action is wherein got off, when the user need receive the MBMS business, terminal receives the MCCH channel according to the MCCH configuration information of storage, thereby obtain the configuration information of MTCH, and on MTCH, receive the MBMS business according to the configuration information of MTCH.When receiving the MBMS business, terminal obtains the modification information of MBMS business by periodically monitoring the MCCH channel, and according to the timely reception of adjusting MBMS Traffic Channel MTCH of the modification information that receives.
When terminal was in the Cell-DCH state, because terminal is keeping being connected of signaling with network side, terminal did not need receiving system message under normal conditions; When the sub-district switching takes place terminal,, after terminal switches to new sub-district, do not need receiving system message because switching command carries enough target cell informations yet.Yet, for the TD-MBMS terminal that is in MBMS activation of service state, if the MCCH channel configuration difference of sub-district before and after switching, terminal need obtain the configuration of the MCCH channel of new sub-district by the system message that reads new sub-district, thereby can continue correctly to monitor the MCCH channel in the new sub-district.
Because the characteristic of MBMS business, in same service area, the configuration of MBMS business is identical, so in general the configuration of MCCH is static, the configuration of the MCCH of each sub-district can be identical in the same service area.In this case, if switch the minizone of terminal in same service area, then do not need frequently to read the system message of switching the sub-district, back, to obtain the configuration of MCCH channel.But, in the present system, terminal is when switching, and whether the configuration of the MCCH channel of sub-district is identical before and after not knowing to switch, and, do not comprise the MCCH channel configuration information that switches the sub-district, back in the switching command yet, thereby cause terminal in order to continue to receive the MBMS business, the read system message repeatedly of having to, this realization and scheduling to terminal brings very big complexity, even influences the experience of user to the MBMS business.
Summary of the invention
Technical problem to be solved by this invention provides in a kind of TD-SCDMA system terminal and obtains the method for MCCH configuration fast.
For solving the problems of the technologies described above, it is as follows to the invention provides technical scheme:
Terminal is obtained the method for MCCH configuration in a kind of TD-SCDMA system, and described terminal switches to Target cell from former sub-district, and described method comprises the steps:
Network terminal sends switching command to terminal, carries the MCCH configuration of sign Target cell in the described switching command and whether disposes identical information element with the MCCH of former sub-district;
Terminal receives switching command, whether the MCCH configuration of determining Target cell according to the described information element in the switching command is identical with the MCCH configuration of former sub-district, if then continue to use the MCCH configuration of former sub-district, otherwise, the MCCH configuration of from the system message of Target cell, obtaining Target cell.
Above-mentioned method wherein, also comprises: after terminal receives switching command, if do not receiving the MBMS business, then do not obtain the MCCH configuration of Target cell.
Above-mentioned method, wherein, described switching command is physical channel reconfiguration message, transmission channel reconfiguration message or radio bearer reconfiguration message.
By above technical scheme provided by the invention as can be seen, the present invention is on the basis of existing TD-MBMS system and TD-SCDMA system switching flow, by in switching command, add terminal switch before and after the whether consistent indication of MCCH channel configuration of sub-district, solved terminal when receiving multimedia broadcast is professional, whenever switch once, read to switch the back problem of cell system message newly with regard to needs, reduced the action of terminal, improved the operating efficiency of terminal.
Description of drawings
Fig. 1 obtains the method for MCCH configuration for terminal in the TD-SCDMA system of the embodiment of the invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
With reference to Fig. 1, the method that terminal is obtained MCCH configuration in the TD-SCDMA system of the embodiment of the invention comprises the steps:
Step 101: when network terminal determined that terminal need be carried out the switching of minizone, whether the MCCH configuration that increases the sign Target cell in sending to the switching command of terminal disposed identical information element with the MCCH of former sub-district;
The concrete information element that increases is as follows:
Information element title: MCCH configuration indication (MCCH configuration indication);
Information element type: Boolean type.When value was " very ", the MCCH configuration of expression Target cell (switching the sub-district, back) was identical with the MCCH configuration of former sub-district (switching preceding sub-district); When value was " vacation ", the MCCH configuration of expression Target cell was different with the MCCH configuration of former sub-district; Default value is " very ".
The information element existence condition: this information element only exists in switching command.
In the TD-SCDMA system, switching command can for: physical channel is reshuffled (PhysicalChannel Reconfiguration), transmission channel reshuffles (Transport Channel Reconfiguration) or radio bearer is reshuffled message such as (Radio Bearer Reconfinguration).
Particularly, terminal reads the MCCH configuration indication in the switching command, if this MCCH configuration indication value is " very ", think that then the MCCH configuration of Target cell is identical with the MCCH configuration of former sub-district, at this moment, do not need to read the system message of Target cell, directly use the MCCH configuration of former sub-district, dispose the MCCH channel of receiving target sub-district according to the MCCH of former sub-district; If this MCCH configuration indication value is " vacation ", think that then the MCCH configuration of Target cell is inequality with the MCCH configuration of former sub-district, the system message that need read Target cell obtains the MCCH configuration of new sub-district.
Certainly, after terminal receives the switching command of network terminal transmission, if do not receiving the MBMS business, then do not need to obtain the MCCH configuration of Target cell, the system message that does not just need to obtain the content in the above-mentioned information element and do not need to read Target cell yet.
In sum, the present invention is on the basis of existing TD-MBMS system and TD-SCDMA system switching flow, by in switching command, add terminal switch before and after the whether consistent indication of MCCH channel configuration of sub-district, solved terminal when receiving multimedia broadcast is professional, whenever switch once, read to switch the back problem of cell system message newly with regard to needs, reduced the action of terminal, improved the operating efficiency of terminal.
