2. Description of the related technique

Mobile communications technology has experienced a rapid, spectacular development that has resulted to an increasing use of telecommunication products such as cellphones. Conventionally, in a communication based on cell phones several types of techniques For example, in a Global Communications System Mobile (GSM) adopts a Multiple Access access technique of Time Division (TDMA) and a duplex duplex technique by Frequency Division (FDD). In GSM, if there is no need for make a call during a cyclic paging (for example, one call every 30 minutes), a cell phone is not will communicate with the GSM for confirmation of the location after a location update procedure with respect to to GSM to save the electronic energy of the cell phone. He GSM system only records the local area (LA) associated with the phone mobile. However, a single location zone can cover more than 100 BTS, each BTS being designated to cover an area specific known as a cell. In case of providing Short message services (SMS) to all cell phones in some specific cells, the GSM system will confirm what cell phones in LA are located in the cells concrete asking all the BTS to call sequentially to all cell phones, and then it get all digital networks of integrated services from mobile stations (MSISDN) of all cell phones in the concrete cells Then the GSM system will provide SMS messages to all cell phones in some cells concrete based on the MSISDN. This inevitable paging increase system load and waste resources from system considerably. Therefore, there is a need for improvement in order to mitigate and / or obviate the problems above mentioned.

Detailed description of the preferred embodiment

With reference to figures 1 and 2, it is shown a well-known GSM network, in which a cell phone 20 is Able to communicate with another cell phone. The telephone 20 Cell phone is also known as Mobile Station (MS). The telephone 20 cell phone is supplied with a particular MSISDN, also known as The cell phone number. In case of receiving a call incoming or starting a call, GSM knows where it is the cellular telephone 20 (for example, in an LA1 corresponding to a BSC 60) asking a Base Position Record 72 (HLR). TO the BSC 60 will then assign one of the BTS (for example, a BTS 30) for communication with the cell phone 20. Every GSM component will be described in detail below.

A Transceiver Base Station (BTS) is adapted to transmit voice to cell phone 20 or to receive 20 cell phone voice. As shown in Figure 1, BTS 30, 31, 32, 33, 34 and 35 are arranged in LA1, BTS 40, 41, 42, 43, 44 and 45 are arranged in an LA2 and some BTS 50, 51, 52 and 53 are arranged in an LA3, respectively.

A Base Station Controller (BSC) is adapted to control each BTS in an LA to communicate with a cell phone. In addition, the BSC is coupled to a center of Mobile switching (MSC) to communicate with it. Each LA It has a unique Location Zone Identity (LAI) for use as your identification For example, the BSC 60 is adapted to control all the BTS in LA1. While entering LA1, the Cell phone 20 will store the LAI corresponding to LA1. Also, the BSC 62 is adapted to control all BTS in LA2. While entering LA2, cell phone 20 will store the LAI corresponding to LA2. The BSC 64 is adapted to Control all BTS in LA3. While entering LA3, the Cell phone 20 will store the LAI corresponding to LA3.

A Visited Position Record (VLR) is adapted to record some MSISDN of each cell phone in an LA and to provide an MSISDN information service to an MSC correspondent. For example, a VLR 65 records the MSISDN of the 20 cell phone when entering LA3. On the contrary, the VLR 65 deletes the MSISDN when the cell phone 20 leaves the LA3. In this way, the MSC 90 can determine whether the telephone 20 cell phone is on LA3 asking VLR 65. Also, a VLR 61 is adapted to record some MSISDN of each phone cell phone in LA1 and LA2 and to provide a service MSISDN information to a corresponding MSC 80. It is understood that a VLR can record the MSISDNs in at least one LA.

GSM can confirm the position of a cell phone asking for the MSISDN stored in a VLR at  through MSC 80 or 90. For example, MSC 90 asks the VLR 65 on the MSISDN of cell phone 20. If the VLR 65 responds to the question, the GSM confirms that the cell phone 20 is found on LA3, otherwise, the cell phone will found outside of LA3.

A 70 Equipment Identification Record (EIR) is adapted to record an international identity of the Unique mobile equipment (IMEI) of a cell phone. The IMEI is a number set by the manufacturer. For example, GSM will record the IMEI on EIR 70 when accessing GSM the first time to Determine the current state of the cell phone. The EIR 70 classifies the cell phone as one of the three lists on the base of the current state of the cell phone. Specifically, a whitelist means that a cell phone is in a state normal, a gray list means that the cell phone is being watched and a blacklist means that the cell phone It has been stolen or is out of order.

A Base Position Record (HLR) is adapted to store, not just basic data, such as services telecommunication specials requested by users, routing messages and designated transfer numbers, but also the identifying data. Each cell phone is Register in an HLR. For example, cell phone 20 is registered on HLR 63 and recorded on VLR 61. When the phone 20 cell moves from one cell covered by BTS 30 to another cell covered by the BTS 50, this means that the phone 20 cell phone moves from LA1 (out of the MSC 80 service) to LA3 (at the service of MSC 90). Cell phone 20 asks MSC 90 to provide you with a communication service, and the MSC 90 compares  the basic data and the identifying data registered in the HLR 63. If the data match, the MSC 90 serves the 20 cell phone and record the MSISDN on VLR 65. It is understood that The MSISDN in VLR 61 will be deleted by MSC 90.

An authentication center 74 (AUC) is adapted to provide parameters required to perform an authentication by cell phone 20. The telephone 20 cell phone will ask the GSM to authenticate by providing same an international mobile subscriber identity (IMSI), a MSISDN or similar. Then the GSM uses some parameters of the cell phone 20 stored in the AUC 74 to authenticate the 20 cell phone. After completing phone authentication 20 cell, the cell phone 20 will be assigned an identity Temporary mobile subscriber (TMSI) and a protocol-based LAI specific, in which the LAI corresponds to the LA of telephone 20 mobile. The above procedure is known as the record of the location. The cell phone 20 will store the TMSI and the LAI. The cell phone 20 will request the GSM to authenticate providing to it the TMSI and the LAI before communicating with GSM In other words, communication between the phone 20 cell phone and GSM is only possible after the end of authentication.

There is no need to update the data of the cell phone 20 when cell phone 20 moved from a cell covered by BTS 30 to a cell covered by BTS 35 because both cells are controlled by MSC 80. However, when the cell phone 20 moves from the cell to another cell covered by the BTS 50, since the cell phone 20 is outside the service of the MSC 80 and in the service of the MSC 90, the cell phone 20 asks the GSM to update the position providing to it the TMSI and the LAI. GSM will erase the MSISDN of cell phone 20 recorded on VLR 61 and will record the MSISDN in VLR 65, and will assign a new LAI corresponding to the LA3 to cell phone 20. The above process is known as location update.

An MSC 76 gateway (GSMC) is coupled to an axis 78 trunk. The MSC 80 is adapted to transmit voice data from cell phone 20 to trunk axis 78 or to receive data from 78 axis trunk voice to be transmitted to cell phone 20. He trunk axis 78 is implemented as an existing network, such as a ISDN, a public switched telephone network (PSTN) or a mobile network public land (RMTP). GSM can be coupled to a line telephone through the PSTN, to a remote MSC through the ISDN or to a GSM of any other Internet service provider (ISP) through the RMTP.

An MSC is one of the switching centers of GSM Many control and authentication procedures are made by the MSC. In case of dialing a telephone number by cell phone 20 (at LA1), BSC 60 asks MSC 80 to Find the position of the number. First, the MSC 80 compares each registration in VLR 61 with the number. If no record matches, MSC 80 reads the records in the HLR to determine the position of the number Therefore, the BSC 60 can connect the BSC 64 to the Communication with another cell phone. Alternatively, the BSC 60 You can connect the trunk shaft 78 for communication with a wired phone

The operations of BSC 60 and 62 are both controlled by the MSC 80. In other words, a single MSC is able to control at least one BSC to provide the service of  communication. The MSC 80 and 90 are both coupled to the GSMC 76 to communicate with axis 78 trunk. This allows a phone call cell phone 20. In addition, a cell phone the GSM service of any ISP can perform a 20 cell phone call and vice versa.

Typical GSM has been described. In case of a communication between the GSM and the cell phone 20, the GSM first determine the location (i.e., LA) of telephone 20 cell phone and assign an appropriate BTS to establish a connection Wireless with cell phone 20. There are three methods made by the GSM to determine the cell phone 20 cell phone and to assign an appropriate BTS. Specifically, a first method is that each BTS transmits a paging signal and then wait for a response from cell phone 20 to determine the cell phone 20 and assign a BTS to establish a wireless connection with the phone 20. This will waste GSM resources and will reduce efficiency. A second method is that the cell phone cell 20 is updated by the GSM when phone 20 enters a new cell. This has the inconvenient that the GSM performs the update a large number of times, which results in a large increase in the burden of GSM A third method is that an LA is made up of many BTS and only a location update is performed when the phone 20 moves from its current LA to a different LA, in which a paging procedure is defined as signals from paging transmitted by all BTS in the same LA. He Third method is adopted by the current GSM.

The cell phone 20 enters a mode of wait when you execute a registration procedure of the location or location update. In this At the moment, GSM only knows the current location (i.e., LA) of cell phone 20 instead of the current cell phone 20 mobile. There are three methods performed by the GSM to determine the cell phone cell 20. The first method is a cyclic paging. To ensure that cell phone 20 is still online and in your cell, the GSM will call periodically to cell phone 20. The cycle period depends on the Applications. For example, the period is 30 minutes. The second method is an active paging that is used when the GSM you receive an incoming call from phone 20. In case the phone 20 is in a cell covered by BTS 33, GSM knows that telephone 20 is in LA1 through the procedure of location update. If there is an incoming call from telephone 20, GSM requests all BTS (for example, BTS 30, 31, 32, 33, 34 and 35) controlled by BSC 60 that perform simultaneously a paging with respect to telephone 20 and wait for a phone call 20. If the answer indicates that the Cell phone 20 is in a cell corresponding to BTS 33, GSM asks BTS 33 to establish a wireless connection and contact phone 20. A third method is a active paging of the cell phone, which is used when a cell phone (for example, cell phone 20) starts a call. In case of dialing the cell phone 20, the phone 20 cell phone will request a connection to the GSM through the BTS 33. In response, GSM communicates with cell phone 20 at through the BTS 33.

In case there are three department stores A, B and C in each cell covered by BTS 33, 43 and 53, respectively, and department stores A, B and C are branches of department stores, if GSM wants to perform a Service of Short Messages (SMS) of "All at 50% discount" to consumers near department stores A, B and C as promotion, it is difficult to achieve the goal without increasing the burden of the GSM. In some area controlled by the army, there is a demand a list of MSISDN to verify the identity of each person. However, GSM is also not able to achieve the goal without increasing the load.

With reference to figures 3 and 4, it is illustrated an island-type mobile communications arrangement according to the present invention BTS 33, 43 and 53 are reallocated as BTS 39, 49 and 59 island, respectively. In addition, the BTS 39, 49 and 59 island are coupled to an island BSC 66 but are not coupled to the BSC 60, 62 and 64, respectively. In addition, an LAI is assigned corresponding to the BTS 39, 49 and 59 island to them. Such as shown in figure 3, the BTS 39, 49 and 59 island are separated. The BSC 66 Island is coupled to an MSC 85 Island and the MSC 85 Island is coupled to a VLR 67 Island.

All cells covered by BTS 30, 31, 32, 34 and 35 correspond to LA1 and are assigned to an LAI particular to communicate with cell phones. Likewise, all cells covered by BTS 40, 41, 42, 44 and 45 are correspond to LA2 and are assigned to a particular LAI for Communicate with cell phones. Likewise, all cells island covered by the BTS 50, 51 and 52 correspond to LA3 and are assigned to a particular LAI to communicate with some cellphones. In addition, all island cells covered by the BTS 39, 49 and 59 island correspond to the LA island and are assigned to a particular LAI in which the BTS 39, 49 and 59 island They are communicating with cell phones. The functionality of BSC 66 Island is the same as that of each of the BSC 60, 62 and 64. Also, the functionality of the island VLR 67 is the same as that of each of the VLR 61, 63 and 65.

The cell phone 20 will ask the GSM to update the position and save the MSISDN of the cell phone 20 in the VLR 67 island while entering the LA island from LA1, since the  Corresponding MSCs are different. It is understood that VLR 61 update the data and the MSISDN of the cell phone 20. By therefore, the island VLR 67 records the MSISDN of all phones Cells in island cells covered by BTS 39, 49 and 59 island. In case of providing an SMS for the promotion from the department stores A, B and C to consumers, the GSM will provide the SMS to all MSISDN recorded on the island VLR 67 sequentially GSM can provide a list of MSISDN reading the island VLR 67.

With reference to Figure 5, the provision of Island-type mobile communications of the invention can provide a special service that includes an SMS, a service of multimedia messages (MMS) or similar to each of about 201 and 202 cell phones. MMS is a type of format for document that includes images, animations, voices or movies.

In sum, the invention assigns a BTS in each LA as an island BTS, assign a particular LAI to the island BTS and record an MSISDN of cell phone 20 on the island VLR 67. As such, the Island-type mobile communications arrangement can know all MSISDNs on the island BTS reading VLR 67 records Island before starting an SMS. The provision of communications Island-type mobiles have substantially the same structure as that of the previous GSM. In addition, neither the communication protocol nor The operation of the GSM are changed by the invention. He mobile location detection method will not imply any additional paging with respect to cell phones, performing the location update only a few times.

As a result, GSM resources are They keep well. In addition, the invention is also applicable to any of the other mobile communications system, such such as the universal mobile telecommunications system (UMTS) or a  third generation mobile communications system, post than any of the mobile communications systems identified above are substantially equal to the GSM except that different protocols are used to communicate with a cell phone, each of the communications systems Mobile identified above is a cell-based system. The cell phone can be replaced by a personal assistant digital (PDA), a smartphone or a laptop that can communicate with mobile communications provisions at  Through a communication module.

Although the present invention has been explained in in relation to their preferred embodiment, it should be understood that they can make many other modifications and possible variations without depart from the spirit and scope of the invention as it see below in this document.
