Description
Technical field
The present invention relates to wireless communication field, relate in particular to method, system, different system switchback equipment and the terminal of a kind of different system switchback.
Background technology
Development along with the communication technology, the manufacturing capacity of terminal is also at development, and present terminal is supported the network of multiple business standard mostly, but generally can a preferential resident network be set for terminal, require terminal in the situation that possible, preferentially reside in this network.But,, along with the change in location of terminal, may need to switch to other networks from preferential resident network when terminal in carrying out the process of business, and reside in and continue to carry out this business in other networks, namely terminal is carried out different system and is switched.When terminal resides in the execution of winding-up in the process of other networks, terminal need to switchback be to preferential resident network from current resident network, and namely terminal need to be carried out different system switchback.
for example, for sharing the second generation communication technology (Second Generation, 2G) data and Common Control Channel (Common Control Channels, CCCH) consideration of pressure, can require to support the multiple types network (as supporting TD SDMA (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA) network and global system for mobile communications (Global System of Mobile communication, GSM) terminal network) preferentially resides in the TD-SCDMA network in communication process, when terminal is initiated speech business in the residential quarter 1 of current resident TD-SCDMA network formats after, due to the network coverage, the a variety of causes such as network capacity and network strategy, terminal need to be carried out different system and be switched, terminal switches to the GSM network from resident TD-SCDMA, and the cell relays of the GSM after switching is continuous carries out speech business, as shown in Fig. 1 (a).
when end is carried out in this speech business, terminal still resides in GSM residential quarter after switching, due to the current resident network of terminal and Location Area Code (the Location Area Code of the preferential residing network of terminal, LAC) difference, therefore, terminal will be initiated LAU/RAU and carry out cell reselection in current resident GSM residential quarter, terminal from current resident GSM residential quarter switchback to the residential quarter 2 of the preferential resident identical standard of TD-SCDMA (it can be the different districts of identical standard that this residential quarter 2 and terminal are carried out the residential quarter 1 of different system when switching), this process needs 5 seconds consuming time, after this, terminal is initiated LAU/RAU again in current resident residential quarter 2, then 5 seconds consuming time.As shown in Fig. 1 (b), be the shared duration schematic diagram of operations in the different system switchback process of this terminal.
In the different system switchback process of above-mentioned terminal, terminal is returned resident twice LAU/RAU of initiation that need of TD-SCDMA network from the on-hook of GSM network and gravity treatment, this twice LAU/RAU process needs 10 seconds consuming time, in these 10 seconds, this terminal can not be paged, therefore cause the paging time-delay of terminal, and twice LAU/RAU process also can produce extra system resources consumption, the lifting interference.
Problem when solving above-mentioned different system switchback, fast return (Fast Return has been proposed, FR) scheme, take terminal from GSM network switchback to the TD-SCDMA network as example, when terminal is carried out different system switchback, send the GSM network channel to terminal and discharge (Channel Release) message, carry in this ChannelRelease message in the adjacent area with the current resident GSM network cell of terminal, standard is the adjacent area message of TD-SCDMA residential quarter, makes terminal can know fast the TD-SCDMA network cell that can carry out different system switchback after on-hook.Specific embodiment has two kinds:
First kind of way: terminal resides in the GSM network and carries out or not in communication process nearby region measurement, after hanging up terminal, base station controller (Base Station Controller, BSC) the adjacent area message of TD-SCDMA standard residential quarter is carried at Channel Release message and sends to terminal, terminal is carried out nearby region measurement according to the adjacent area message of the TD-SCDMA standard residential quarter that receives, select optimum TD-SCDMA network cell to carry out switchback, terminal is initiated LAU/RAU in switchback TD-SCDMA network cell extremely, as shown in Fig. 2 (a).
The second way: terminal resides in the GSM network and carries out in communication process, BSC sends the adjacent area message of TD-SCDMA standard residential quarter by measuring message (Measurement Information) to terminal, terminal is carried out nearby region measurement according to this adjacent area message to the residential quarter of TD-SCDMA standard, and to BSC reporting measurement result.After hanging up terminal, BSC determines optimum TD-SCDMA network cell according to the measurement result that receives, and the adjacent area message of TD-SCDMA network cell that should optimum is carried at ChannelRelease message and sends to terminal, make terminal can be directly carry out switchback according to the adjacent area message of the TD-SCDMA network cell of the optimum that receives, its process schematic diagram is also as shown in Fig. 2 (a).
above-mentioned first kind of way and the second way are for the different system switching mode shown in Fig. 1 (a), terminal is after on-hook and need to carrying out different system, need to not initiate LAU/RAU in current resident GSM residential quarter and carry out cell reselection, but the adjacent area message of the TD-SCDMA standard residential quarter that utilizes directly that BSC sends is carried out cell reselection, can save and initiate 5 seconds shared durations of LAU/RAU, reached and reduced the purpose that terminal can not paged duration, as shown in Fig. 2 (b), the shared duration schematic diagram of operations in different system switchback process for this terminal under above-mentioned first kind of way and the second way.
But, owing to there being different protocol versions under the consolidated network standard, therefore, support the terminal of diversity of protocol versions for fast return (Fast Return, FR) tenability of function is different, for the terminal of not supporting the FR function, if still carry out the words of different system switchback according to above-mentioned first kind of way and the second way, may cause the switchback failure of different system, make the reliability of different system switchback and success rate reduce.
For example, there are different protocol versions: R4, R5, R6, R7 and R8 in the GSM network, and in gsm protocol 44.018-630, because the ADA compiler does not support the relation of negative need to introduce CRGP-031155, but mistake has occured, until gsm protocol 44.018-750 is just revised by CR GP-061161 when introducing this CR GP-031155.And above-mentioned first kind of way and the second way are introduced when the GSM procotol is the R6 version, make and support the terminal of R6.30 GSM version in the past not support Fast Return function, if the adjacent area message of the TD-SCDMA standard residential quarter of not supporting that the terminal of Fast Return function receives that BSC issues is also carried out different system switchback, may be because terminal can't correctly be processed signaling, the problem that causes terminal to crash.

Be described in detail below in conjunction with the scheme of Figure of description to the embodiment of the present invention.
Embodiment one:
As shown in Fig. 3 (a), be the method flow diagram of a kind of different system switchback of the present embodiment one, the method specifically comprises:
Step 101: the ability label of whether supporting Fast Return function that receiving terminal reports.
The spare bits whether terminal supports the ability label of Fast Return function can pass through terminal capability cell (Information Element, IE) reports.Particularly, in the connection of communications field circuit domain, the terminal capability cell can be class indication (Classmark), in the connection of carrying out packet switch, the terminal capability cell can be MS wireless access (MS Radio Access).The below describes the mode of terminal to report ability label in this step 101 take Classmark as example.
In the scheme of this step 101, described ability label can be carried in the spare bits of terminal capability cell.
Particularly, according to the definition of 3GPP agreement to Classmark2, Classmark2 is total 24bit always, all information that comprised Classmark1, and expanded the ability information that the part terminal is supported, as terminal whether support remarks (Postscript, PS) ability information, whether support machine translation (Machine Translation, MT) ability information of end-to-end note etc., its structural representation as shown in Figure 4.
101 couples of Classmark shown in Figure 4 of this step modify, place in its spare spare bits and be used for the ability label whether the expression terminal supports Fast Return function, by the different content of this ability label, the expression terminal can support maybe can not support Fast Return function.For example: when the numerical value of the ability label that arranges in the spare spare bits is 1, represent this terminal support Fast Return function; When the numerical value of the ability label that arranges in the spare spare bits is 0, represent that this terminal do not support Fast Return function.The different values that in the present embodiment scheme are the handling capacity sign represent that whether terminal supports Fast Return function, does not make restriction to the concrete content of ability label.
Arrange in Classmark when terminal self whether support the ability label of Fast Return function after, need this Classmark is reported to core net, particularly, state residing according to terminal is different, terminal will report by different modes this Classmark, include but not limited to following several mode:
1, when terminal during as caller, terminal reports to core net by " CM service request (CM Service request) " message with the content of Classmark;
2, when terminal when called, terminal reports to core net by " paging response (Paging Response) " message with the content of Classmark;
3, when terminal is carried out IMSI DETACH, terminal is carried Classmark and is reported to core net in " IMSI detach indication " message;
4, when terminal position upgrades, terminal is carried Classmark and is reported to core net in " position updating request (Location updating request) " message;
5, when terminal was carried out the RRC connection, terminal was carried Classmark and is reported to core net in " rrcConnectionSetupComplete " message;
6, when terminal is carried out Ciphering, if what carry in the Classmark that terminal reported before carrying out Ciphering is the information of supporting algorithm A5/1, but the algorithm of current terminal residing network support is A5/2, the algorithm that is terminal to report self support is different from the algorithm of the current residing network support of terminal, this moment, MSC was sent to BSS with " Classmark request " message, BSS initiates the CLASSMARKINTERROGATION flow process to terminal, and sends " Classmark enquiry " message to terminal; Terminal to report " Classmark change " message is to BSS, and carries Classmark report to core net in this " Classmark change " message.
This step 101 also is not limited to realize by the modification to other-end ability cell.
Step 102: when terminal is carried out the switching of different system, according to the ability label of described terminal, judge whether described terminal supports Fast Return function.
If terminal reports by spare spare bits in Classmark the ability label of whether supporting Fast Return function to core net, in the scheme of this step 102, core net can be identified the ability label in the spare spare bits in the Classmark that receives, and judges whether this terminal supports Fast Return function.
This step 102 can be to carry out judging immediately whether terminal supports the FastReturn function after different system is switched in terminal, can be also the decision operation of carrying out any time before terminal is carried out different system switchback.
Step 103: when described terminal was supported Fast Return function, after indicating terminal switches, resident network side issued be used to the adjacent area message of carrying out different system switchback to terminal.
Support Fast Return function if judge described terminal in step 102, when core net determines that this terminal is carried out different system switchback afterwards again, can utilize the adjacent area message that receives to know fast the network cell that can carry out different system switchback, therefore, no matter whether current terminal needs to carry out different system switchback, after core net can be switched to terminal, resident network side issues Fast Return signaling, and being used to indicate the rear resident network side of terminal switching can issue be used to the adjacent area message of carrying out different system switchback to terminal.Afterwards, after terminal is switched, resident network side can be when terminal need to be carried out different system switchback (when satisfying different system switchback condition, business as current in terminal is finished), send the Channel Release message of carrying adjacent area message to terminal, as shown in Fig. 3 (b); Terminal is switched rear resident network side also can before terminal need to be carried out different system switchback, send the Channel Release message that carry adjacent area message, as shown in Fig. 3 (c) to terminal.
Terminal can be carried out network reselection according to frequency point information, the scrambling code information for the adjacent area of carrying out different system switchback of carrying in the message of adjacent area after receiving this adjacent area message.Particularly, terminal can be carried out network reselection according to the dual mode shown in Fig. 2 (a).
