In the following embodiment, the working process of the present invention is described in detail by using 6 mobile phone chips for serial connection.
In practical application, as shown in fig. 2, at this time, the integer N is 6, each of the 6 mobile phone chips includes a first serial communication terminal 1 and a second serial communication terminal 2, where the second serial communication terminal 2 of the first mobile phone chip is connected to the first serial communication terminal 1 of the second mobile phone chip, the second serial communication terminal 2 of the second mobile phone chip is connected to the first serial communication terminal 1 of the third mobile phone chip, and so on, the second serial communication terminal 2 of the fifth mobile phone chip is connected to the first serial communication terminal 1 of the sixth mobile phone chip, the second serial communication terminal 2 of the sixth mobile phone chip is connected to a wired interface, and the wired interface is connected to other devices.
In the prior art, a GSM base station belongs to a full-duplex working mode, and a mobile phone chip belongs to a half-duplex working mode, so that when the mobile phone chip is used for replacing a traditional base station chip, a problem that data cannot be transmitted and received simultaneously exists. Therefore, in the embodiment of the present invention, the 6 mobile phone chips are set in different working timeslots, as shown in table 1.
Table 1 mobile phone chip working time slot distribution table
The mobile chip 1 is used as a Broadcast Control Channel (BCCH) when transmitting signals, and operates in the downlink working time slot 0 at this time, and is used as a Random Access Channel (RACH) when receiving information, and operates in the downlink working time slot 3. The mobile phone chip 1 is used as a broadcast control channel for broadcasting the public information to all mobile users from the GSM base station provided by the embodiment of the present invention, which indicates that the GSM base station provided by the embodiment of the present invention is working, including the normal working or abnormal working condition. When the mobile phone chip 2 transmits a signal, it is used as a Traffic Channel (TCH), and at this time, it works in the downlink working time slot 1, and when the signal is received, it is also used as a Traffic Channel (TCH), and it works in the downlink working time slot 4. The mobile phone chips 3-5 have the same working mode as the mobile phone chip 2, but the data transmitting and receiving processes are in different working time slots. The mobile phone chips 2-5 are used as service channels and are arranged in different working time slots. When the GSM base station works, if uplink data is received in a certain working time slot, the uplink data is transmitted to a corresponding mobile phone chip, the unique identification code of the uplink data is added into the uplink data by the mobile phone chip, then the uplink data is transmitted to a next-stage mobile phone chip by the mobile phone chip and finally transmitted to a wired interface, and at the moment, the wired interface can add the receiving time slot of the mobile phone chip into the uplink data and continuously transmit the uplink data to other equipment. For example, data packets from the mobile phone chip 1 all include the unique identification number 1, data packets from the mobile phone chip 2 all include the unique identification number 2, and so on, so as to realize the identification of the uplink data and the external data.
The mobile phone chip 6 works in a downlink working time slot of 5-7, when the GSM base station has no information transmission, the mobile phone chip 6 uniformly transmits a DUMMY signal to indicate that no information transmission exists at present, and the GSM base station has no load in the working time slot; and, at this time, the mobile phone chip 6 does not receive a signal. In addition, the mobile phone chip 6 works in a standby channel, can cope with the situation of excessive uplink data, and is convenient to upgrade the GSM base station. When the mobile phone chips 2-5 are not loaded, the DUMMY signal is also transmitted as the mobile phone chip 6, which indicates that the GSM base station is not loaded in the time slot now, and the detailed description is omitted here.
In practical application, the transmitting time slot of each mobile phone chip is different from the transmitting time slots of other mobile phone chips, and the receiving time slot of each mobile phone chip is different from the receiving time slots of other mobile phone chips. For example, the working time slot of the mobile phone chip 1 for transmitting data is the downlink working time slot 0, and the working time slot for receiving data is the downlink working time slot 3. Therefore, the difference between the working time slots of the mobile phone chip 1 for transmitting data and receiving data is 3 working time slots, and the data transmitting and receiving processes are not influenced. The method for allocating the working time slots for the mobile phone chip 1 allocates the working time slots for the mobile phone chips 2-6, can meet the requirements of practical application, and is not described herein.
Optionally, when the wired interface receives downlink data, acquiring a unique identification number carried by the downlink data, and transmitting the downlink data to a mobile phone chip corresponding to the unique identification number according to the unique identification number; or acquiring a transmitting time slot carried by the downlink data, acquiring a unique identification number corresponding to the working time slot, and transmitting the downlink data to the corresponding mobile phone chip according to the unique identification number. For example: when the mobile phone chip 2 receives the uplink data and transmits the uplink data to the wired interface, the uplink data sequentially passes through the mobile phone chip 3, the mobile phone chip 4, the mobile phone chip 5 and the mobile phone chip 6. When the wired interface receives the downlink data and transmits the downlink data to the mobile phone chip 2 corresponding to the working time slot, the downlink data sequentially passes through the mobile phone chip 6, the mobile phone chip 5, the mobile phone chip 4 and the mobile phone chip 3.
In practical application, the embodiment of the present invention may further set that the transmission time slots of at least two mobile phone chips are discontinuous, and the reception time slots are also discontinuous. When a user requests for a call, mobile phone chips are dynamically allocated to the user, so that the load of each mobile phone chip is more balanced. For example, when only one user needs to perform voice call, the mobile phone chip 2 can be selected to work; when two users exist, the mobile phone chip 2 and the mobile phone chip 3 can be selected to work; when there are multiple users, distribute multiple mobile phone chips. Through dynamic allocation of the mobile phone chips, one or more mobile phone chips can be prevented from being in a working state all the time, and other mobile phone chips do not work, so that the load of each mobile phone chip is more balanced, and the service life of the GSM base station is prolonged. Of course, a person skilled in the art can also set the usage order of the mobile phone chips, and allocate the uplink data in a polling mode or a random mode, which can also solve the above technical problems and achieve similar technical effects. The invention is not limited.
Optionally, in the embodiment of the present invention, one of the at least two mobile phone chips performs time synchronization with an external GSM network adjacent to the GSM base station, and the mobile phone chip is used as a time slot synchronization source of the GSM base station. The mobile phone chip transmits broadcast signals to other mobile phone chips, so that the other mobile phone chips except the mobile phone chip carry out working time slot synchronization when receiving the broadcast signals. For example, in the embodiment of the present invention, as shown in table 1, the mobile chip 1 keeps synchronization with the external communication network connected to the GSM base station, and the mobile chip 1 transmits the BCCH signal as the synchronization signal source of the mobile chips 2 to 6, so that the mobile chips 2 to 6 keep synchronization with the operating time slots thereof. In practical application, the embodiment of the invention can also adopt an independent synchronization module to transmit synchronization signals to the mobile phone chips 1-6 to realize the synchronization of the working time slots of the 6 mobile phone chips.
In practical application, in the GSM base station provided by the present invention, each mobile phone chip allocates different transmission time slots and reception time slots, so that the time of the data transmission process and the time of the data reception process of all the mobile phone chips are not overlapped. Therefore, in the embodiment of the invention, the antenna interfaces of all the mobile phone chips are directly connected to the same antenna, thereby simplifying the circuit structure of the GSM base station.
In practical application, at least two mobile phone chips with the same model are adopted in the embodiment of the invention, so that clock sources and power supplies of all mobile phone chips can be connected to the same clock source and power supply. Of course, at least two mobile phone chips with different models can be adopted, and the requirements of each mobile phone chip on a clock source and a power supply need to be met during configuration. Those skilled in the art can set the setting according to the specific situation, and the invention is not limited.
In a second aspect, an embodiment of the present invention further provides a communication system, which is manufactured by using the GSM base station. For example, the GSM base station provided in the embodiment of the present invention may be added to a 4G base station, and the GSM base station and the 4G base station may form a communication system of a 2G +4G dual-mode base station; the GSM base station provided by the embodiment of the present invention may also be added to a router to form a router with the GSM base station function. Of course, those skilled in the art may also apply the communication system provided in the embodiment of the present invention to other systems according to actual situations to form a more complex communication system, and the present invention is not limited thereto.
