Jessica, need your help.

This should be a known issue, PS is in "searching" state until user selects the preferred network type in Settings. I've talked to Shawn, and it should be a modem issue related to preferred network type.

I would recommend you to take a look at bug 928297 too. That is the Gaia side we are working on to support data calls on multi ICC devices.

Hi jessica, 1. I cat these logs by I changed ril_const.js and set debug flag to true. 2. data registration process in dual SIM mode is different with single SIM card mode.

(In reply to sam.hua from comment #8) > Hi jessica, > > 1. I cat these logs by I changed ril_const.js and set debug flag to true. > 2. data registration process in dual SIM mode is different with single SIM > card mode. Thanks for your response. Just wanted to make things clearer. This bug is about getting data connection in SIM1 and bug 944231 is about getting data connection in SIM2. Currently for us, after boot up, data registration for both SIMs are in searching state while voice registrations are in registered state. After selecting manually the preferred network type, we can get data registration of SIM1 registered, at that point data connection can be established successfully on SIM1 (this is what this bug is reporting). However, I can not get data registration registered on SIM2 no matter how I select the preferred network type, this is reported in bug 944231. You said that data registration process in dual SIM mode is different, what exactly is the difference? Are there extra steps that we need to take care of? Thank you.

It is impossible to let two sim cards keep data connection at the same time.So our modem just keep data connection when it is necessary. And,SIM 2 will always work in GSM only.so it is useless to set preferred network to SIM 2. Maybe u can force the perferredNetworkType to GSM Only in the Gecko and check what happened.

Sam, we are not trying to "let two sim cards keep data connection at the same time", we just want to be able to use data connection in SIM1 and then be able to "switch to" SIM2. Data connection from only ONE sim will be established at the same time. But we need to have "data registration" registered before setting up data connection [1], so here are the two issues found: 1. we can get "data registration" registered on SIM1 only after manually selecting preferred network type (this bug) 2. we can't get "data registration" registered on SIM2 even after selecting GSM only for preferred network type (bug 944234) I think Shawn will explain to you on your conference call today.

Hi We should get the right APN settings for sim2, then we can setup the data call.But i can't find the correct settings for SIM2 in the log. Could u do a fake apn settings in the RadioInterfaceLayer for SIM2?

I can't find the way to set the apn and ril.data.enabled of SIM2 by UI operation. how to do it?

Sorry, I think i mistake the bugs.. It is for SIM1 to establish data link.

Please refer to comment 6, the gaia part is in Bug 928297. And to enable data connection on SIM2, first go to Settings -> SIM Manager, and choose SIM 2 for DATA, then go to Settings -> Cellular & Data -> SIM 2 to turn on data connection on SIM 2. The SIM Manager patch has landed already, see bug 932731.

FYI I am able to setup data calls for ICC card 1 without problems. By applying the patch from bug 933203 once the device boot the APN settings for the two ICC cards should get configured.

Jose, you mean you don't need to manually select preferred network type to make ICC card 1 data connection work? That's strange... does this happen only in Taipei?

It is same in Shanghai,i have to change preferred network to make sim1 setup the data call.

(In reply to Jessica Jong [:jjong] [:jessica] from comment #18) > (In reply to José Antonio Olivera Ortega [:jaoo] from comment #17) There is no need in my case to change the preferred network type. Data calls for the ICC card 1 work correctly with Movistar ICC card in Spain.

Thanks José and sam for the feedback. sam, were you able to find the cause of this?

Hi Jessic, I updated my code today, and now I can use data network just by open the data connection. gecko:0e3362fb5625eb6d98c7617b1b3019a2cc553d47 gaia: f64d282b6b44eaaf8cddc8be8f3250cb6fbacd95

Hi Jessica, I means if we get the right APN settings and setup the data call, we will have the data connection. So if u fail, u could find out 1. have u get the right APN settings ? 2. have u setup the data call? if have not, maybe u should find what cause it.

What I have been trying to say is that the PRECONDITION for setting up data call is to have data registration registered. If data registration is not registered, RIL will not try to setup data call. So, to answer your questions... 1. Yes 2. No, it is because data registration is in searching state, which is the problem reported in this bug.

In our design of dual cards, we can setup data call even if data isn't registed

(In reply to sam.hua from comment #27) > In our design of dual cards, we can setup data call even if data isn't > registed Then you are not following AOSP design. Could you solve this on modem side? Thank you.

It is modified to support data service of two cards.

for example. In dsds mode,if u are using data service of SIM1 and want to send MMS by SIM2,you will have to deactivate the SIM1 data connection first then setup data connection of SIM2.

(In reply to sam.hua from comment #30) > for example. > In dsds mode,if u are using data service of SIM1 and want to send MMS by > SIM2,you will have to deactivate the SIM1 data connection first then setup > data connection of SIM2. Yes, we have taken care of that too, see bug 926372. But the precondition for setting data call is still the same: to have data registration registered.

In ril_worker.js setRadioEnabled: function setRadioEnabled(options) { Buf.newParcel(REQUEST_RADIO_POWER, options); Buf.writeInt32(1); Buf.writeInt32(options.enabled ? 1 : 0); Buf.sendParcel(); changed to setRadioEnabled: function setRadioEnabled(options) { Buf.newParcel(REQUEST_RADIO_POWER, options); Buf.writeInt32(2); Buf.writeInt32(options.enabled ? 1 : 0); Buf.writeInt32(CLIENT_ID?0:1); //SIM1 1;SIM2 0; Buf.sendParcel(); this can set SIM1 to auto attach the data network,u can try to get the precondition.

Hi Sam: Why add extra parameter in ril_worker.js to make auto attach work? If this is a place to make things work, is it possible to do the stuffs in RILD instead? For pure AOSP, this is not done by telephony framework side, IMO, it is not proper to do such specific things in gecko either. Please let me know any comments you have. Thanks!! sku

You can add sprd or DSDS flag.

Hi Jessica, "autoAttach" is defined in the Settings, if we choose SIM1 as default data sim card, it should be set to "1", and the other SIM card won't try to register data network at the beginning.I think gecko should add this control to support this setting. and, sprd extend the interface of rilc, REQUEST_GPRS_ATTACH,REQUEST_GPRS_DETACH,to control the data network.it could be found in sprd_ril.h. Gecko can use them to attach/detach when switch the simcard for data service.

You can add sprd or DSDS flag. Hi James/Sam: Thanks for lecture me the fugu behavior. My original though is: 1. RILD can use +CGATT=1 to auto attach PS domain during boot-up, then we got both SIM with PS auto attached. 2. radioInterfaceLayer will do the control of which SIM is used to setupData by user's desire. (there is a setting to control this part as you said) BTW, I said pure AOSP behavior is for single SIM w/o any modification from Google definitely. Please correct me if anything is wrong. Thanks!! shawn

Hi jessica, Only one sim card could be auto attached. if u switch the card for PS, the active one should disconnect data link and DEATTCH GRPS, then the other could do attach and setup data call.

could u give the AOSP link to me? Thanks!

You can get the AOSP from the instructions of below link: http://source.android.com/source/downloading.html And, The latest version is "android-4.3_r2.1"

The patch in comment 32 doesn't work. Using REQUEST_GPRS_ATTACH/REQUEST_GPRS_DETACH mentioned in comment 35 does work, but we will need to add these extra quirks for fugu devices. :( What is more, do we need to send GPRS_ATTACH request after airplanemode off/on? What if we lost PS registration temporary, do we need to send GPRS_ATTACH again?

I think we should add the control in the gecko. Don't need it in the cases u mentioned.

I will try to make the "AutoAttach" flag to work, it's a important flag to modem.I will info u if I succeed.

Hi jessica, I updated libreference-ril_sp.so, and please use comment 32. can u try it? if it is ok,i will update it in the github.

(In reply to sam.hua from comment #43) > Hi jessica, > I updated libreference-ril_sp.so, and please use comment 32. > > can u try it? > > if it is ok,i will update it in the github. I used the new libreference-ril_sp.so but it does not work. From the logs, I see libreference-ril_sp sending 'AT+SAUTOATT=0' to modem, but the PS are still always in searching state.

It should send "AT+SAUTOATT=1" for SIM card1 to auto attach gprs. could u give me the log?

Log for auto-attach.

(In reply to sam.hua from comment #46) > It should send "AT+SAUTOATT=1" for SIM card1 to auto attach gprs. > could u give me the log? I have attached the logs. From the SENDTRUE spec I googled, 0 is auto-attach? description 0 Set to auto attach 1 Set to manual attach(cancel auto attach) Note: Command AT+SAUTOATT is SENDTRUE’s specific.

Hi jessica, You can ask Ken to get the spec for at commands of our modem. Actually I can't find the description of the SAUTOATT command in the document, but i think it should be AT+SAUTOATT=1 to set auto-attach from the code in Android Framework. Do u send it with 1 for SIM1? I find that u sent AT+AUTOATT=0 for SIM1 in the log.

(In reply to sam.hua from comment #49) > Hi jessica, > > You can ask Ken to get the spec for at commands of our modem. > > Actually I can't find the description of the SAUTOATT command in the > document, but i think it should be AT+SAUTOATT=1 to set auto-attach from the > code in Android Framework. > > Do u send it with 1 for SIM1?

Hi sam, Sorry, I think I missed something before. Now I can see SIM1's data registration state registered. But how do we switch to SIM2? We can not call setRadioEnabled() each time we want to switch the default SIM for data call...

Hi Jessica, if u switch the card for PS, the active one should disconnect data link and DEATTCH GRPS, then the other could do attach and setup data call. maybe u should add a new process for DSDS data control in gecko instead of reusing the setRadioEnabled().

(In reply to sam.hua from comment #52) > Hi Jessica, > if u switch the card for PS, the active one should disconnect data link and > DEATTCH GRPS, then the other could do attach and setup data call. > > maybe u should add a new process for DSDS data control in gecko instead of > reusing the setRadioEnabled(). So we still need to use REQUEST_GPRS_ATTACH/REQUEST_GPRS_DETACH as mentioned in comment 40, right? Then, what is the auto-attach flag in setRadioEnabled() for? And, does gecko need to send REQUEST_GPRS_ATTACH each time we leave airplane mode? Will modem auto-attach after a temporary lost of data registration state? Thanks.

Yes, we need REQUEST_GPRS_ATTACH/DETACH action in the switch process. When we want to use SIM2 in the case of default PS is SIM1, we should: 1. deactive SIM1 and detach SIM1 2. attach SIM2 and setup data call 3. deactive SIM2 and detach SIM2 when ps completed 4. attach SIM1 and setup data call SIM1. or should be : 1. Switching to SIM2 for PS 2. PS transaction 3. Switching back to SIM1. The auto flag: It is to indicate the default sim card for PS.So we don't need to send REQUEST_GPRS_ATTACH when we leave airplane mode, the modem should know which sim card will auto attach the PS and which one won't. The auto flag is changed only in the case of the change for default SIM card of PS.

But it seems that the auto-attach flag can be sent only in setRadioEnable(), how can we set the auto-attach flag if we are only switching the default SIM for PS?

Hi Jessica, yes,but the flag seems to do work after setRadioEnable(). It is a bit complex in data control of DSDS in our Android framework. So ,could u give me design documents about DSDS?

PLease refer to: https://bug917705.bugzilla.mozilla.org/attachment.cgi?id=8342704

Hi jessica, You can get the manifest.xml from Ken of our android framework. The two new files,MsmsGsmDataConnectionTracker.java and MsmsGsmDataConnectionTrackerProxy.java, are used to control the PS in DSDS. Maybe u can reference it.

Attach/detach data registration on demand. This is needed for fugu devices only.

Actually, this is a workaround for a timing issue that I met: if the RadioInterface, that is becoming non-default for data, observes the 'ril.data.defaultServiceId' first, it will disconnect its data call and remove the data type from RILNetworkInterface.connectedTypes; later when the other RadioInterface, that is becoming default for data, observes the change and check for gNetworkManager.active.type, it will return 'NETWORK_TYPE_MOBILE_OTHERS' since it is no longer in RILNetworkInterface.connectedTypes. By the way, we are not handling data default service id change for non-default data calls, i.e. switching default sim for data while a mms send is in progress.

What if we don't? From my tests, if we don't detach here, the other SIM's data registration can still be attached, but when setting up data connection, modem always return failure in this case.

Hsinyi, after a quick scan, the following are what I found in partner's android code: On radio power, RIL will set the auto-attach flag on the default sim for data. (We are not doing this, instead we directly attach data registration on the default data sim for data.) When switching default sim for data (and setting up data connection), their RIL will check the 'mAutoAttachOnCreation' flag, if this flag is set means they don't need data registarion to setup data connection. Besides from that, their procedure is similar to what we have done: 1. disconnect all data calls on previous default sim for data. 2. detach data registration on previous default sim for data after data calls are disconnected. 3. If 'mAutoAttachOnCreation' is false, attach data registration on current default sim for data, otherwise setup data connection directly on current default sim for data. You can check out the checkAndSwitchPhone() and onDisconnectDone() in MsmsGsmDataConnectionTrackerProxy.java

We are moving dsds data setup handling to RadioInterfaceLayer, so that we can monitor data calls from every client correctly. We should move these to 'DataConnectionManager' when it is ready, see bug 905568.

The idea was to set _dataDefaultClientId to null to differentiate it from 0 (SIM1), then null would mean that we haven't read successfully from the db.

Could you explain why line #844 is needed? This is for the case where data is enabled, but there is no active data calls, then we need to call updateRILNetworkInterface() to trigger data call setup for the new selected client/sim. Thank you Hsinyi for the review, please let me know if there is anything unclear or we can discuss f2f.

Addressed comment 67, 71 and 72. Some other changes: - change the default values to -1 for id variables, I think it's clearer now. - use the _pendingDataCallRequest as requested.

Rebased based on Part 1, v2. After adjusting the logic in handleDataClientIdChange() in Part 1 v2, some extra code are introduced.

How > does partner's android code do? Partner's android code will wait for data state change to setup the pending data call. In our case, RIL will setup data call directly and will fail cause data registration is not registered, and once data registration becomes registered, we will try to setup data call again. We can also wait for data state change to setup the pending data call, but then the flow would be quite different with and without RILQUIRKS_DATA_REGISTRATION_ON_DEMAND.

Yes, and also on bootup, we will try to attach data registration on the default sim for data, but it would fail due to 'radio not available', so we need to set it again on radio on.
