Below in conjunction with Fig. 1, to method provided by the invention, be elaborated, the cellphone subscriber sends the workflow of asking Message Processing, when adopting the inventive method to handle, can comprise the steps.
Step 100: begin to carry out the inventive method.
Step 101: create a hash index array, a session status machine information array and a method state machine information array.
A) WAP gateway distributes a session for each cellphone subscriber that reaches the standard grade, an element of the corresponding hash index array of each session id.
B) the element memory mobile phone user of session status machine information array and session that WAP gateway is set up, the corresponding mobile phone of each the session number group element user that reaches the standard grade.
C) state machine information handled of method state machine information storage of array current phone request message, once mutual between corresponding cellphone subscriber of each method state machine array element and the application server.Session id under storing simultaneously, each session promptly shown in Figure 2.
D) size of each array can be decided according to the WAP gateway existing network serviceability that operator clearly stipulates.
Step 102: read user's request message from message queue, the parameter of sign cellphone subscriber identity is the IP address and the port of mobile phone in the message, carries out the Hash operation according to WAP gateway address port and cellphone subscriber's address port, calculates Hash KEY value.The subscript of the corresponding hash index table of KEY value.
Step 103: search in KEY the element whether have session information to hash index table (being the hash index array) according to the KEY value, for example, the KEY value is 17, then searches the 17th element to the hash index table and whether has session information, do not exist to forward step 104 to, exist then to forward step 105 to.
Step 104: the element that in session status machine information array, finds a sky, set up WAP gateway and this cellphone subscriber's session, and session information is stored in this sky element, and the following table of this element is as session id, simultaneously store session ID in the concordance list in KEY element and the hash index array associate.If be not free element in the session status machine information array, then refusal and this cellphone subscriber set up session.
Step 105: after cellphone subscriber and WAP gateway are set up session, mobile phone sends a PUL message or accepts a PUSH message, whether there is the method state machine information of mobile phone requesting method under judging under the session, do not exist to forward step 106 to, exist then to forward 107 to.
To not setting up session, mobile phone is the method request message of initiation just, and WAP gateway can directly be abandoned.
Step 107: according to request message that receives and the mobile phone requesting method state machine information array element that finds, handle the mobile phone request message, upgrade canned data in this state machine information array element.
The response message that the WAP gateway application server is returned is handled, according to the method state machine ID that carries in the response message, directly in method state machine information array, search, the response message that finds the reprocessing of requesting method information element to receive, the new information of recording status machine is in the state machine information array element.After the processing of method state machine flow process finishes, the element of the method state machine information array of release busy then.After method state machines all under the affiliated session was finished dealing with, then the element of the session status machine information array of release busy was used in order to other.Can use simultaneously timer cycle to check the session information array, clear up overtime session.
Step 108: finish to carry out the inventive method.
As shown in Figure 2, it has comprised the structural representation of each array, below in conjunction with Fig. 2 the present invention is further explained for WSP carries out data processing.
Step 201: WSP provides a message queue to accept all message, no matter message be terminal or server end, the unified message queue that is stored in, the address that the request message that mobile phone sends is formed with the IP address port of mobile phone and WAP gateway is to as a token of, and the response message that server returns is a sign with method state machine ID.
WAP gateway obtains message from message queue, judge this message be client or server end, the message of client can be operated the lookup method state machine through Hash by IP address and port, and server end can be according to method state machine ID directly to middle inquiry.
Step 202: the element store session ID in the hash index array, when receiving user's request message, the Hash operation is carried out in the IP address of mobile phone and the IP address and the port of port and WAP gateway, calculate a Hash KEY value.The subscript of KEY value representation hash index array directly searches whether deposit the session id of having set up in the hash index array.Because the hash index array is a static allocation, so get surplus according to the greatest member number of array to the KEY value.Hash-collision may occur like this, session id can not represent it is the session id that this cellphone subscriber sets up in the concordance list.Therefore in case of necessity, also need in session status machine information array, to search as linked list order.
In the session status machine information array as shown in Figure 2, user's [1] (being session [1], session id [1]) KEY value is 1, the index of its corresponding hash index array [1], the method [0] of method state machine information array.
Step 203: each reaches the standard grade mobile phone just and WAP gateway is set up a session, the subscript of session status machine information array is distributed to each session id, in this session id storage hash index array, when in the hash index array, finding this session id, directly search the session of foundation in the session status machine information array.For the phenomenon of hash-collision, be 17 o'clock as Hash KEY value among Fig. 2, corresponding 3 sessions comprise Session:28, Session:14, Session:0 (being session id); After WAP gateway is received the mobile phone request message, from the hash index array, at first find session 28, then this three sessions, 28,14,0 chained list of being formed is searched, for example make sequential search.Search criterion can be the IP address and the port of mobile phone, also can only be the IP address of mobile phone; Because when each mobile phone is reached the standard grade, WAP gateway can distribute a unique IP address for it.If do not find, then create a new session, be linked to session 0 back, form the chained list of 4 elements.
Step 204: after mobile phone and WAP gateway were set up session, mobile phone began and the server swap data, by PULL or PUSH method.Method state machine array index is assigned as method state machine ID, finds state machine ID in the session information array, just can directly find element in the method state machine array.The corresponding a plurality of methods of each session possibility are made sequential search so the identical method state machine element of affiliated session also can be formed chained list.The present invention is to various lookup methods and unrestricted.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection range of claims of the present invention.
