Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 2, the processing method of a kind of session management instructions that provides for the embodiment of the invention, this method may further comprise the steps:
When the Context identifier that arbitrary Context identifier that step 202, this current session management instructions carry and the session management instructions that receives before carry is identical, stop that the low session management instructions of priority carries should identical Context identifier correspondence bearer context flow process, and upgrade the flow state information and the operation result information of the identical Context identifier that the low session management instructions of this priority carries;
The operation result information of step 203, all Context identifier of carrying according to the current sessions supervisory instruction is returned session management instructions executable operations result to upper layer application.
Concrete, the session processing unit obtains the Context identifier that this session management instructions carries after receiving the AT instruction of upper layer application transmission, and is saved in the multi units tube reason structure of storage area.The relevant information of one or more cid that each session management instructions carries constitutes a group information.As shown in Figure 3, schematic diagram for multi units tube reason structure, it is including but not limited to following information: bOperCode (group action type), bCidNum (cid number in the group, be the effective length of atCidInfo array), bCidCnt (counter, the unclosed cid number of flow process in this group), and atCidInfo is used to deposit the relevant information of current group of interior each cid, comprise cid (the local sign of context), bCidOperStatus (context flow state), bPrimCid (cid of the pairing default bearer of context), bProcType (corresponding flow process type).Certainly, according to the actual needs, can also increase all the other related information content.After preserving successfully, each cid that session management instructions is carried initiates the flow process of corresponding bearer context successively.It should be noted that when successfully not getting access to the Context identifier of session management instructions, directly respond executable operations result failure to upper layer application.
Before the flow process of initiating the corresponding bearer context of cid that the current sessions supervisory instruction carries, need according to the processing that conflicts of the priority of session management instructions.When judging priority, the session management instructions priority of same type is identical; The session management instructions type is not simultaneously, the session management instructions priority of deexcitation type is the highest, the priority of other session management instructions, the rule that is higher than the priority of current sessions supervisory instruction according to the session management instructions priority that receives is earlier determined priority.Concrete, whether other session management instructions that receive before judging in the storage area carry this cid, if do not carry, then initiate the flow process of the corresponding bearer context of this cid, after the flow processing for the treatment of the corresponding bearer context of this cid finishes, the related data of upgrading in the multi units tube reason structure gets final product, as change bCidCnt, bCidOperStatus etc.; If carry identical cid, whether the type that then needs to judge the session management instructions that receives before that carries this cid is identical with the type of current sessions supervisory instruction, if identical with the type of current sessions supervisory instruction, then the flow state information updating of this cid that the current sessions supervisory instruction is carried for before the flow state information of this cid of carrying of the session management instructions that receives; If it is inequality with the type of current sessions supervisory instruction, and when the session management instructions type of current reception was non-deexcitation, the flow state information updating of this identical Context identifier that the session management instructions of this current reception is carried was for finishing and upgrading operation result information; If it is inequality with the type of current sessions supervisory instruction, and when the session management instructions type of current reception is deexcitation, the flow process of the corresponding bearer context of this identical Context identifier that the session management instructions that receives before stopping carries, the flow state information updating of the same context sign that session management instructions is before carried is for finishing, and upgrades the flow state information and the operation result information of the described identical Context identifier that described current sessions supervisory instruction carries.
After the flow process of the corresponding bearer context of all cid that session management instructions carries all finishes, bCidCnt is 0, the operation result information of all cid that carry according to the current sessions supervisory instruction this moment determines the executable operations result of this session management instructions, and return execution result to upper layer application, for example, when the flow process of arbitrary cid correspondence that the current sessions supervisory instruction is carried is failed, return the executable operations failure to upper layer application; The flow process of all cid correspondences of carrying when this session management instructions all during success, is returned the executable operations success to upper layer application.
The method that this embodiment of the invention provides is not limited to LTE, can also use with other scenes in, the method of using the embodiment of the invention to provide, when a plurality of session management instructions issue and different sessions supervisory instruction when carrying identical cid simultaneously, a plurality of session management instructions can carry out flow process separately smoothly, avoid clashing, improved the processing speed of session management instructions, and can make a session management instructions carry a plurality of cid simultaneously, and each cid in the same instruction can walk abreast and handle, and has improved the session management instructions treatment effeciency thus.
The session management instructions that upper layer application is issued to ESM generally comprises: the session management instructions of the flow process that is used to trigger the activation, be used to trigger the session management instructions of deexcitation flow process, and be used to trigger session management instructions of new technological process more etc.Providing more specifically execution mode below, as shown in Figure 4, is that example describes the method that the embodiment of the invention provides with the flow process that triggers the activation, and comprises the steps:
The activation process of the corresponding bearer context of this cid that step 403, initiation current sessions supervisory instruction are carried is upgraded the group information of current sessions supervisory instruction, and is upgraded the flow state information of this cid, execution in step 406;
Whether the session management instructions that carries this cid that receives before step 404, the judgement realizes mobilizing function, if, then the flow state information synchronization of this cid correspondence that the current sessions supervisory instruction is carried for before the flow state information of this cid of carrying of the session management instructions that receives; Otherwise, execution in step 405;
The activation process of step 406, the corresponding bearer context of the current cid of wait finishes, and upgrades the group information of current cid place session management instructions, and the flow state information of upgrading this cid correspondence is for finishing.
Each cid that the current sessions supervisory instruction is carried carries out aforesaid operations successively, counter in the group information of this session management instructions is 0, end is to the operation of current sessions supervisory instruction, the operating result of all cid that carry according to the current sessions supervisory instruction determines the operating result of this session management instructions, and return the executable operations result to upper layer application, for example, arbitrary cid flow operations failure that the current sessions supervisory instruction is carried is then returned the executable operations failure to upper layer application; When all cid flow operations that the current sessions supervisory instruction is carried are all successful, return the executable operations success to upper layer application.
As shown in Figure 5, new technological process is that example describes the method that the embodiment of the invention provides to trigger more, comprises the steps:
The more new technological process of the corresponding bearer context of this cid that step 503, initiation current sessions supervisory instruction are carried upgrades the group information of current sessions supervisory instruction, and upgrades the flow state information of this cid, execution in step 506;
Whether the session management instructions that carries this cid that receives before step 504, the judgement realizes update functions, if, then the flow state information synchronization of this cid correspondence that the current sessions supervisory instruction is carried for before the flow state information of this cid of carrying of the session management instructions that receives; Otherwise, execution in step 505;
The flow process of step 506, the corresponding bearer context of the current cid of wait finishes, and upgrades the group information of current cid place session management instructions, and the flow state information of upgrading this cid correspondence is for finishing.
Each cid that the current sessions supervisory instruction is carried carries out aforesaid operations successively, counter in the group information of current sessions supervisory instruction is 0, end is to the operation of current sessions supervisory instruction, the operating result of all cid that carry according to the current sessions supervisory instruction determines the operating result of this session management instructions, and return the executable operations result to upper layer application, for example, arbitrary cid flow operations failure that the current sessions supervisory instruction is carried is then returned the executable operations failure to upper layer application; When all cid flow operations that the current sessions supervisory instruction is carried are all successful, return the executable operations success to upper layer application.
As shown in Figure 6, be that example describes the method that the embodiment of the invention provides to trigger the deexcitation flow process, comprise the steps:
The deexcitation flow process of the corresponding bearer context of this cid that step 603, initiation current sessions supervisory instruction are carried is upgraded the group information of current sessions supervisory instruction, and is upgraded the flow state information of this cid, execution in step 606;
Whether the session management instructions that carries this cid that receives before step 604, the judgement realizes the deexcitation function, if, then the flow state information synchronization of this cid correspondence that the current sessions supervisory instruction is carried for before the flow state information of this cid of carrying of the session management instructions that receives; Otherwise, execution in step 605;
Each cid that the current sessions supervisory instruction is carried carries out aforesaid operations successively, counter in the group information of current sessions supervisory instruction is 0, end is to the operation of current sessions supervisory instruction, the operating result of all cid that carry according to the current sessions supervisory instruction determines the operating result of this session management instructions, and return the executable operations result to upper layer application, for example, arbitrary cid flow operations failure that the current sessions supervisory instruction is carried is then returned the executable operations failure to upper layer application; When all cid flow operations that the current sessions supervisory instruction is carried are all successful, return the executable operations success to upper layer application.
