The present invention relates to the field of mobile communication services, and in particular, to a method and system for implementing a message push service. BACKGROUND Currently, there are two basic classifications of message push services: location-based message push services and message push services based on specific user groups. Location-based message push service, also known as cell based location advertisement (Location Based Advert), refers to the identification of mobile terminal users in a specific cell through specific technologies, and uses the current mobile communication network and SMS/MMS push platform to achieve specific Locations (eg, airports, stations, hotels, shopping malls, tourist attractions, shopping districts, etc.) provide personalized information services for specific customer groups (eg, travelers, diners, shoppers, etc.). A message push service based on a specific user group, also called a group message, refers to pushing a text message/mMS message to a certain certain user group through a short message/mMS push platform (eg, a merchant provides information to its VIP customer, a company, etc.) service). In combination with the foregoing two service features, a third type of location group message push service may also exist, that is, to push messages to mobile terminal users who are both in a specific user group and in a specific cell. Although mobile operators have aggressively developed location advertising services by introducing service providers (SPs) in combination with content publishers, they have created a promising value-added service industry. However, since there is currently no technology for controlling messages to achieve effective push, resulting in waste of resources, and easily causing complaints from end users, service providers and content publishers also face difficulties in fee settlement.

The contract/advertisement (pending approval, normal, rejection, abolition) of the above four states is automatically changed to 'expired, status' after the expiration of its set period. Embodiment 1 FIG. 4 and FIG. 5 are flowcharts of a location-based message push service of the present invention. Referring to FIG. 4, the illustrated flow is mainly for filtering the user and the hot zone, and includes the following steps (step S401 - step S407): Step S401: The IP gateway 204 receives the user location information from the signaling system, including the user mdn and The cell Id sends a message to a service processor 203X according to the user mdn number and the configured distribution policy. Step S402: The service processor 203X records the hot zone information edited by the cell Id and the portal (the hot zone is composed of multiple cells) Compose) to match the hot zone; if the match fails, exit and then process the next user; Step S403: The service processor 203X determines whether the current state of the hot zone is active or not; if it is in the invalid state, exits and then processes the next user; Step S404: The service processor 203X determines whether the user is in the blacklist (the blacklist is on the portal) If the user is in the blacklist, the user is logged out and then processes the next user; Step S405: The service processor 203X determines whether the number of advertisements received by the user on the day reaches the system configuration day. The number of receipts can be received; if it has been reached, exit and then process the next user; the purpose of this filtering is to prevent users from receiving too many advertisements and one complaint in one day. Step S406: The service processor 203X determines whether the number of advertisements received by the user in the hot zone reaches the maximum number of receivables set by the hot zone; if it has been reached, exits, and searches for an advertisement in the hot zone of the next match; The purpose of item filtering is to prevent users from receiving too many advertisements in a hot zone and causing other hot zone advertisements to be unavailable. Step S407: The service processor 203X searches for an effective advertisement in the hot zone and transmits it. The process of specifically finding an advertisement is described with reference to FIG. Referring to FIG. 5, the illustrated flow is a detailed description of step S407, that is, a process of finding an effective advertisement under the hot zone, including the following steps (step S501 - step S511): Step S501: the service processor 203X is in the hot zone Find all the advertisements in the 'normal, state, one-by-one traversal process; Step S502: Determine whether the type of the advertisement is a positioning or positioning group; if not one of the two types, exit and then process the next advertisement; Step S503 : determining whether the current time is in the sending period of the advertisement (the advertisement has multiple sending periods); if not in all the sending periods, exiting and then processing the next advertisement; Step S504: determining the sent item of the advertisement in the sending period Whether the number reaches the set value; if it has been reached, exits and then processes the next advertisement; Step S505: Determine whether the number of sent items of this type of the contract belongs to the set value; if it has been reached, exit and then process the next advertisement ; To further explain, if the advertisement is of type X, it belongs to contract A, and it is judged whether the number of sent items of the X type of contract A has reached the contract setting value (X is a positioning or positioning group). Step S506: determining whether the user attribute (according to the number segment entered by the portal can match whether the user is a local user or a foreign user or a provincial user in the province) matches with the sending object set by the advertisement; if not, exits and then processes the next advertisement; Step S507: It is determined whether the user has received the advertisement in the last N days (N days is the number of repeated transmission intervals in the advertisement attribute), and if it has been received, exits and then processes the next advertisement; the purpose of filtering is to prevent the user Repeatly receiving the same advertisement frequently; Step S508: determining whether the advertisement type is a positioning group; if not, only the positioning type (determined by step 502), proceeding to step S510 to send an advertisement; if positioning the group type, entering Step S509. The purpose of this control is to reduce the delivery range of advertisements, only for those who are in the group edited by the content publisher (one is a VIP customer, etc.) and enter the user zone in the set hot zone. ad. Step S509: determining whether the user is in the group set by the advertisement; if not, exiting and then processing the next advertisement; Step S510: After the above-mentioned series of filtering conditions are met, sending an advertisement to the user; the service processor 203X delivering the message To the IP gateway 204, protocol adaptation (supporting CMPP/SGIP/SMGP/MM7) by the IP gateway 204 is sent to the SMS gateway or multimedia message center. At the same time, the service processor 203X records the transmission details into the physical database, and updates related data such as the number of advertisements sent and the number of articles sent by the contract. Step S511: Determine whether the number of advertisements sent to the user reaches the maximum number of deliverables set by the hot zone; if not, continue to search for the next advertisement of the hot zone; if it has been reached, end the business process of finding the advertisement. Embodiment 2: FIG. 6 is a flowchart of a group-based message push service according to the present invention, including the following steps (step S601 - step S614): Step S601: The service processor 203 periodically scans the group type in the normal state. ad. In order to prevent the multiple service processors 203N from repeatedly processing the same group advertisement, the multi-service processor 203N also adopts a load sharing strategy: the number of weights configured for each node of the service processor 203 is modulo according to the group advertisement Id. According to the modulo result, it is distributed to each service processor 203N for processing. Step S602: determining whether the current time is within the sending period of the group advertisement; if not, exiting and then processing the next group advertisement; Step S603: determining whether the number of sent items of the sending period reaches the set value of the group advertisement If it has been reached, exit and then process the next group advertisement; Step S604: Determine whether the number of sent group types of the contract to which the advertisement belongs has reached the contract setting value, if it has been reached, exit and then process the next group Advertisement; Step S605: After the above judgment, the group advertisement can be sent, and all users in all the sending groups set for the group advertisement are traversed. All group users are loaded into the memory of the business processor 203 and dynamically updated with the portal operator's editing, user ordering/unsubscription. Step S606: In the process of traversing the user, determining whether the current time is still within the sending time period set by the advertisement; if not, exiting and then processing the next advertisement; considering the large number of group users, the traffic when sending Control, may have been limited by the delivery period before traversing all users. Step S607: In the process of traversing the user, determining whether the number of sent items in the current period reaches the set value of the advertisement; if it has been reached, exiting and then processing the next advertisement; considering that the advertisement setting may be smaller than the group The number of users needs to be judged. Step S608: In the process of traversing the user, determining whether the number of sent group types of the contract to which the advertisement belongs has reached the set value of the contract, and if so, exiting and then processing the next advertisement; Step S609: determining that the user has received the same day Whether the number of advertisements has reached the maximum allowable reception value of the system configuration. If it has been reached, exit and then process the users in the next group; this configuration item is to avoid complaints caused by users receiving too many advertisements in one day. Step S610: determining the user attribute (according to the number segment entered on the portal, the user can be matched locally. Whether the user or the foreign user or the province user in the province matches the sending object set by the advertisement; if it cannot match, exits and then processes the user in the next group; Step S611: Determine the user in the last N days (N days is the advertising attribute) Whether the advertisement has been received within the number of repeated transmission intervals, if it has been received, exits and then processes the user in the next group; the purpose of this filtering is to prevent the user from repeatedly receiving the same advertisement frequently; Step S612: After satisfying After the above series of filtering conditions, the advertisement is sent to the user; the service processor 203X delivers the message to the IP gateway 204, and the IP gateway 204 performs protocol adaptation (supports CMPP/SGIP/SMGP/MM7) to the short message gateway or the multimedia message center. At the same time, the service processor 203X records the transmission details into the physical database, and updates related data such as the number of advertisements sent and the number of articles sent by the contract. Step S613: Whether all the users in all the sending groups set by the advertisement are traversed; if the traversal is not completed, the processing flow of the user in the next group is continued; if the traversal has been completed, the business processing flow of the group advertisement is ended. Then processing the next group advertisement; Step S614: Whether to traverse all the group advertisements in the 'normal state'; if not traversing, continue the business process of the next group advertisement, if the traversal is finished, the current timing is ended Business processing of scanner scanning. 7 is a flow chart of a method for monthly settlement of a contract. Taking the location type as an example, the method includes the following steps: Step S701: The task of the database 202 counts the sum of the number of sent advertisements of all advertisements of the type of the contract under the contract, PHS and this month. The sum of the number of sent PMS; the execution period of the contract may exceed one month, so PHS >= PMS. Step S702: Determine whether the number of sent and the PHS of the contract positioning type are still smaller than the number of the PFC of the contract positioning type. When the number of sent packets is less than the number of billing, each one is billed. When the number of sent packets exceeds the number of bills, the excess is not billed. The business logic processing controls that the number of sent items is definitely not exceeding the sum of the number of bills + the number of gifts. Step S703: If PHS < PFC, it indicates that the number of sent items has not reached the contractual agreement. The number of billing, at this time the contract positioning type settlement fee: PF = PMS * Positioning type settlement amount I PFC. Further explanation: Positioning type settlement amount / PFC gets the cost of each advertisement, and multiplies it by the monthly delivery amount PMS. If PHS >= PFC, the number of sent packets has reached or exceeded the number of bills agreed in the contract, and the excess is not included in the number of gifts. At this time, the contract location type settlement fee: PF = (PMS - (PHS - PFC)) * Positioning type settlement amount / PFC. Further explanation: PHS - PFC can get the number of gifts sent, and then subtract the PMS from the current month to get the number of bills in the monthly delivery volume, and multiply the cost of each advertisement: PFC. Step S704: Obtain a contract settlement type settlement fee PF of this month. According to the same method, it can be calculated: the settlement fee GF of the group type, and the settlement fee PGF of the location group type; thus, the PF + GF + PGF can obtain the current month settlement fee of the contract. In summary, according to the embodiment of the present invention, the service provider can settle the monthly settlement fee according to the settlement fee of the contract, and the flexible setting of the number of the three types of advertisements in the contract, the number of gifts, and the amount of the offer. The rich and varied billing strategy and package scheme facilitates the service provider to conduct business, and also greatly reduces the advertising operation cost for the content publisher. It is to be understood that the specific procedures and components of the present invention are set forth by way of example only and not as a limitation of the invention. The invention may be embodied in a variety of other various modifications and changes without departing from the spirit and scope of the invention. The deformation P should fall within the scope of protection of the appended claims.
