See also shown in Figure 2ly, Fig. 2 has disclosed a detailed process of embodiment of the invention activation release of PDF context.
(1), the concrete application module in the user terminal generates and comprises tear down parameter in interior CGACT order;
Concrete application module is when generating the CGACT order, comprise the state parameter in this order, and the CID of the PDP Context of appointment, specifying PDP Context can be one, also can be a plurality of, comprise tear down parameter in addition, the concrete value of tear down parameter can be determined according to user's instruction, in the state parameter is 0 o'clock, and this CGACT order is removed activation command for CGACT.
(2), concrete application module comprises tear down parameter with this and sends to communication interface modules in interior CGACT order;
Step (1) has been described how to generate and has been comprised tear down parameter in interior CGACT order, is not difficult to be realized according to table 1 and prior art.
(3), communication interface modules generates corresponding activation release of PDF context message according to this CGACT order, and indicates in this message and remove all PDP Contexts that activation is used identical pdp address with the PDP Context of described appointment and is in state of activation;
(4), communication interface modules sends to core network with this activation release of PDF context message by Radio Access Network;
(5), after core network receives the message that subscriber equipment sends over, analyzing this message is activation release of PDF context message, and this message requires to remove all PDP Contexts that the PDP Context that activates described appointment uses identical pdp address and is in state of activation; And
(6), core network finds out all PDP Contexts that use identical pdp address and be in state of activation with the PDP Context of described appointment, and removes and activate these PDP Contexts;
Step (6) can also comprise afterwards:
(7), core network finish remove activation manipulation after, the communication interface modules in subscriber equipment sends to remove to activate finishes message;
(8), further, if have RAB (carrying of Radio Access Bearer Radio Link) between core network and the subscriber equipment before PDP Context is disengaged and activates, then carry out the RAB releasing operation between core network and the subscriber equipment, this step is disclosed by prior art, no longer describes in detail herein.
(9) communication interface modules notifies this CGACT order executed of concrete application module to finish in subscriber equipment.
By foregoing description, the embodiment of the invention can once removed the releasing activation manipulation of realizing in the activation process a plurality of PDP Contexts, has effectively improved the service efficiency of communication equipment.
See also shown in Figure 3ly, step (3) can specifically comprise:
Step 301 receives the CGACT order;
Step 302, utilizing the value of the state parameter that comprises in this CGACT order to determine this CGACT order is that CGACT removes activation command;
Step 303 judges this CGACT removes in activation command whether comprise second parameter, i.e. if tear down parameter is execution in step 309;
Step 309, the PDP Context to described CGACT removes each appointment in the activation command all generates a PDP Context that comprises this appointment in interior activation release of PDF context message;
Step 310, in each activation release of PDF context message indication remove to activate with this message in the PDP Context that comprises use identical pdp address and be in all PDP Contexts of state of activation.
Concrete when indicating, a particular information unit (Information Element) can be set in activation release of PDF context message, and finish by this particular information unit is provided with corresponding value, for example be set to 1.
If in step (1), the CGACT order that concrete application module in the user terminal generates does not comprise tear down parameter, will judge this CGACT order in step 303 so and not comprise the teardown parameter, can also at this moment comprise the steps that (this is not a prior art? can make existing goal of the invention? why on earth introduce this? different with prior art, prior art is had improvement):
Step 304 is determined described CGACT and is removed the number N of the PDP Context of appointment in the activation command more than or equal to 2;
Step 305 is inquired about the employed pdp address of PDP Context of described appointment;
Step 306 is determined M PDP Context according to the pdp address that inquires and is used an identical pdp address, and M is an integer, and more than or equal to 2;
Step 307 to this M PDP Context, generates an activation release of PDF context message, and selects a PDP Context as the appointment PDP Context in this activation release of PDF context message in this M PDP Context arbitrarily;
Step 308, in this activation release of PDF context message indication remove to activate with this message in the PDP Context that comprises use identical pdp address and be in all PDP Contexts of state of activation.
In step 307, to this M PDP Context, can only generate an activation release of PDF context message, also can generate a plurality of;
If there is one group of PDP Context to use address IpAddr1 in addition, another group PDP Context uses address IpAddr2, and IpAddr1 and IpAddr2 are inequality, to these two groups of PDP Contexts, can select only to generate two activation release of PDF context message so.
Certainly in step 303, judge this CGACT remove comprise second parameter in activation command after, also can execution in step 304 to 308, to those use the PDP Context of identical pdp address select to generate an activation release of PDF context message get final product (? comprise second parameter, handle all the same? why on earth does that also want second parameter? the feature of 304-308 goes for two kinds of situations: comprise second parameter or do not comprise second parameter).
When indication is removed activation and is specified PDP Context to use identical pdp address and be in all PDP Contexts of state of activation, can be by in activation release of PDF context message, setting a particular information unit, and the value that this particular information unit is set is made as 1 and realizes, whether described particular information unit is used to represent to remove and activates all that use identical pdp address and be in the PDP Context of state of activation;
Step (5) can specifically comprise:
Step 51, core network receives the message that subscriber equipment sends;
Step 52 confirms that this message is activation release of PDF context message;
Step 53 judges that this message requires releasing to activate all PDP Contexts that use identical pdp address and be in state of activation with the PDP Context of described appointment;
Step 53 specifically can comprise the steps:
Judge whether comprise particular information unit in this message, described particular information unit is used to represent whether remove all PDP Contexts that activation is used identical pdp address with the PDP Context of described appointment and is in state of activation; And
When comprising particular information unit in this message, the value of further judging this information unit is 1.
In actual applications, core network may receive many activation release of PDF context message, and described message all requires to remove all PDP Contexts that activation is used identical pdp address with the PDP Context of appointment and is in state of activation, the PDP Context that appointment in two or the multiple messages might occur wherein uses identical address, after executing a message so, during another message below carrying out, whether the PDP Context of appointment uses identical address in the PDP Context that can further judge appointment in this another message and the message of having carried out.
If in step (6), can select directly to send to remove to activate completed message to subscriber equipment; If not, remove to activate with described another message in the PDP Context of appointment use identical pdp address and be in all PDP Contexts of state of activation.
Further, in step (1), concrete application module is when generating CGACT releasing activation command in the subscriber equipment, whether a plurality of PDP Contexts that can also inquire about appointment use identical pdp address, when using different pdp addresses, CGACT removes in the activation command and to the PDP Context that uses different pdp addresses different tear down parameters can be set (this thought should be included in the method for essence of this patent, be not replenish this one or two just passable, this can relate to the variation of entire method, all replacement schemes, should be included in the upper method, retell replacement scheme then, and replacement scheme is to have substituted entire method, or step, should be clear and definite, the seedling seedling you say excellent, the change of one or two feature sometimes can cause the variation of whole proposal, I just ran into this situation now, here can be described as further qualification, with the conflict that prevents from when adding the teardown parameter, may occur), carry out different releasing activation manipulations in order to indication, when for example CID1 uses different pdp addresses with CID2, can select to remove and activate the PDP Context that all use identical pdp address and be in state of activation with CID1, and remove activation CID2.
Except that table 1, the CGACT command syntax can also be as shown in table 2 respectively,
The new CGACT command syntax of table 2
| Order | Possible response |
| +CGACT＝[<state>[，<cid>，[，<cid >，[，...]]]][，<tear?down>] | OK ERROR |
| +CGACT？ | +CGACT:<cid>，<state> [<CR><LF>+CGACT:<cid>， <state> [...]] |
| +CGACT＝？ | +CGACT:(list?of?supported <state>s) |
Compare with table 1, tear down parameter is placed on the last of AT order, the back of the PDP Context of i.e. all appointments, tear down parameter can be placed on before the PDP Context of first appointment in addition, these two kinds different form implications are identical, meaning all requires to carry out the releasing activation manipulation of same type to the PDP Context of all appointments, at this moment if the PDP Context of appointment is a plurality of and when using different pdp addresses, PDP Context CID1 and CID2 that two appointments are for example arranged, and the IpAddr2 that IpAddr1 that CID1 uses and CID2 use is not simultaneously, require to remove activation CID1 and CID2, require to remove all PDP Contexts that activation is used all PDP Contexts of IpAddr1 and used IpAddr2, and can not require to remove activation CID1 simultaneously, and all PDP Contexts of use IpAddr2.
