804; HLR/HSS selects according to called network in the step 803, only is that speech business is an example here with the bearing capacity, and other data services are analogized; Inquiring the User Status of preserving at HLR/HSS is MSC address and the VLR number of the corresponding CN1 of 2G access style of activated state; Then send the MAP request message that Provides Roaming Number to CN1, said message is carried the called IMS I1 under the 2G access style, and said message is also carried the MSC number of CN1;

Flow is referring to the step 404 in the prior art called flow～417.

The called voice service flow process of double-mode and double-standby terminal UE is set up and is accomplished since then.Called data traffic flows HLR/HSS selects CN3 to obtain roaming number, and from AN2 paging double-mode and double-standby terminal UE, whole process is similar, no longer is repeated in this description.

To combine Figure 11 to realizing that based on the double-mode and double-standby terminal of Fig. 9 framework the flow process of called service is described in detail below.

1101～1102, with the step 401 of prior art, 402 identical.

1103, HLR/HSS finds 2 the User Status that IMSI corresponding related with called number MSISDN of preservation, and selects access style by following mode:

If the User Status of 2 IMSI that this called number is corresponding all is an attached state; MSC address and the VLR number of CN3 under the promptly both in store 2G access style; MSC address and the VLR number of CN3 under the also in store 3G access style, then HLR/HSS selects access style according to the bearing capacity in the MAP routing inquiry message: if bearing capacity is speech business, preferentially select the 2G access style; If bearing capacity is the facsimile service in the data service; The preferential 3G access style of selecting if bearing capacity is the video traffic in the data service, is then only selected the 3G access style.

If having only the User Status of the corresponding IMSI of 2G access style among 2 IMSI of this called number correspondence is attached state,, select the 2G access style for the facsimile service in speech business and the data service; For the video traffic in the data service, judge whether the terminal has the ability that data service is revised as speech business, if any, select 2G to insert, otherwise will refuse current video call.

1104; HLR/HSS only is that speech business is an example with the bearing capacity according to the access style of selecting in the step 1103 here, and other data services are analogized; Inquiring the User Status of preserving at HLR/HSS is MSC address and the VLR number of the corresponding CN3 of 2G access style of activated state; Then send the MAP request message that Provides Roaming Number to CN3, said message is carried the called IMS I1 under the 2G access style, and said message is also carried the MSC number of CN3;

Flow is referring to the step 404 in the prior art called flow～417.
