Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application, as detailed in the accompanying claims, rather than all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Related concepts or nouns referred to in this application are explained first:
pico base station (Pico Site): the radio coverage unit (rru) is a miniaturized, low-power and low-power indoor coverage radio frequency unit, that is, an indoor base station, and the functions completed by the radio coverage radio frequency unit are basically the same as those of the traditional rru for macro coverage, and the radio coverage radio frequency unit has the functions of a receiver and a transmitter, that is, digital signals (firstly converted into intermediate frequency signals) are converted into radio frequency signals at a far end, and then amplified and transmitted; or the radio frequency signal received by the receiving antenna is converted into a digital signal and then transmitted to the baseband processing unit. The pico base station comprises an intermediate frequency module, a transceiver module, a power amplifier module, a filtering module and other functional modules, and the baseband function is completed by a baseband processing unit.
Macro base station (Macro Site): the large base station is erected on an iron tower, generally has three sectors, is covered in all directions, has larger power and wider coverage, and is provided with a special machine room for storing equipment. The configuration in the machine room comprises: the system comprises a control module, a radio frequency module, a transmission module, a combining and branching unit, a matched power supply (mains supply, electric power storage and alternating current screen), a lightning protection box, an environment control box (comprising three probes), an air conditioner, fire-fighting equipment and the like. The macro base station is connected with an antenna above the iron tower through a feeder line. The advantages are that: the power is high, and the coverage radius is wide; the capacity is large; the reliability is good. Disadvantages: the price of the equipment is high; the machine room and a special power supply system are needed, and the construction cost is high; is not suitable for moving and has poor flexibility.
The pico-base station fuses the gateway: the device is used for converting and integrating information transmission modes between all the pico-base stations and a core network into an Internet protocol network so as to uniformly manage and mutually convert and communicate, and has the functions of storage, receiving and sending.
Temporary mobile subscriber identity (Temporary Mobile Subscriber Identity, TMSI): by which is meant that the global system for mobile communications can provide security measures in view of the security of the mobile subscriber identity, i.e. the identity transmitted wirelessly over the air interface is replaced by a temporary mobile subscriber identity instead of an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI). The two can be mutually converted according to a certain algorithm. The visitor location register may assign a TMSI to a visiting mobile subscriber that is limited to use within the visitor service area.
In the prior art, due to the characteristic of large coverage of a macro base station, the macro base station is not suitable for carrying out accurate regional broadcast aiming at terminal equipment in a cell, so that a pico base station with smaller coverage compared with the macro base station is adopted for carrying out regional broadcast forwarding.
The pico-base station is directly connected with the core network for information interaction processing, and although the pico-base station is directly connected with a plurality of terminal devices within a certain range, the pico-base station cannot be used as an execution main body for sending broadcast information to the terminal devices due to TMSI limitation of frequent change of codes, and the terminal devices only accept communication signaling which is sent by the core network and carries correct TMSI, so that the pico-base station and the connection device between the pico-base station and the core network can only exist as transfer devices.
When a broadcast message needs to be sent in batches in a certain area, the corresponding pico-base station of the broadcast area needs to be found according to the broadcast area, then the corresponding server is found according to the pico-base station, and then the broadcast content is sequentially sent to the terminal equipment connected with the corresponding pico-base station through the servers.
According to the regional broadcast method, after a broadcast request is acquired through the pico-base fusion gateway, a target pico-base station which needs to transmit broadcast content is determined according to a broadcast region in the broadcast request, and then the broadcast content is transmitted to terminal equipment connected with the corresponding target pico-base station according to a stored correspondence table of the target pico-base station and the TMSI, so that the technical problem in the prior art is solved.
Fig. 1 is a schematic structural diagram of an regional broadcast system according to an embodiment of the present application. As shown in fig. 1, the regional broadcast system includes a pico-base convergence gateway 101, a pico-base 102, a terminal device 103, and a core network 104. The plurality of terminal devices 103 access the nearby pico-base stations 102 in a wireless manner, the plurality of pico-base stations 102 access the pico-base station convergence gateway 101 in a wired or wireless manner, the pico-base station convergence gateway 101 is responsible for managing the accessed pico-base stations 102, and the pico-base station convergence gateway 101 accesses the core network 104 in a wired manner.
The pico-base station convergence gateway 101 is connected with a plurality of pico-base stations 102 to achieve convergence management of the pico-base stations 102, and the pico-base station convergence gateway 101 is connected with the core network 104 through a single gateway, so that unified management of communication signaling of the plurality of pico-base stations 102 is achieved, and connection relations between the pico-base stations and the TMSI are recorded according to authority of unified management of the communication signaling.
The pico-base station convergence gateway 101 is also connected with the terminal equipment 105 of other management systems, and the broadcast request is directly sent to the pico-base station 102 in the corresponding area through the pico-base station convergence gateway 101, and because the micro-signal coverage of the pico-base station 102 has the characteristics of continuous sheet formation and mutual overlapping, the number and the relative positions of the terminal equipment 103 in the range can be determined according to the strength of the terminal equipment 103 received by the pico-base station 102, and then the broadcast request is forwarded to the accessed terminal equipment 103 through the pico-base station 102, so that the synchronous sending of the regional broadcast is realized.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flow chart of a regional broadcast method according to an embodiment of the present application. As shown in fig. 2, the method includes:
s201, a leather base station fusion gateway acquires a broadcast request, wherein the broadcast request comprises a broadcast area and broadcast content;
specifically, the broadcast request is generated according to the requirement of the user, when the user needs to send broadcast information to all terminal devices in a specific area, the broadcast request can be generated according to the required broadcast area and broadcast content, for example, text message information is sent to all mobile phones currently surfing the internet in the area A, and then the broadcast request with the area A as the broadcast area and the text message information as the broadcast content is generated.
Because the pico-cell has the characteristic of small signal coverage, a relatively accurate location range can be obtained by the pico-cell. When the terminal equipment in a certain area needs to be broadcasted, the corresponding pico-cell base station in the area can be searched, and the corresponding pico-cell base station is transmitted to the terminal equipment after being transmitted to the pico-cell base station, so that the relative accurate range positioning is realized.
And the terminal equipment of the management system sends a broadcast request to the pico-base station convergence gateway, namely, the broadcast request information is directly sent to the pico-base station convergence gateway without being processed by a core network server, so that the computing resources of the core network are saved.
S202, the pico-cell fusion gateway determines the pico-cell existing in the broadcast area as a target pico-cell according to the broadcast request;
specifically, the pico-cell fusion gateway receives the broadcast request and then obtains the broadcast area and the broadcast content corresponding to the broadcast request through reverse analysis.
The broadcast area is a geographical range with preset position marks, for example, the broadcast area may be a geographical range according to administrative area division basis, a spatial range according to building identification division, or a signal coverage area according to signal distribution rule division.
When the pico-base station is installed, longitude and latitude coordinates of an installation position are automatically acquired, the acquired longitude and latitude coordinates are sent to a pico-base station fusion gateway for storage, the pico-base station fusion gateway stores the pico-base station and the longitude and latitude coordinates corresponding to the pico-base station into an installation position corresponding table, and identification information of a building and a signal coverage radius range of the pico-base station of a user terminal are acquired and stored into the installation position corresponding table.
After determining the broadcast area, it is necessary to determine which pico-stations are within the broadcast area, for example, according to a broadcast request that the broadcast area is a factory shop identifier, first, the pico-stations corresponding to the factory shop identifier are found in the installation location correspondence table, and these pico-stations are marked as target pico-stations to send broadcast contents.
The broadcast content may be in at least one of video form, audio form, or text form.
And S203, the pico-base station fusion gateway transmits the broadcast content to terminal equipment corresponding to the Temporary Mobile Subscriber Identity (TMSI) corresponding to the target pico-base station according to the corresponding relation table of the current target pico-base station and the TMSI.
Specifically, when the terminal device sends the mobility management signaling to the core network through the pico-base station, the mobility management signaling belongs to important and confidential transmission information, so that the temporary mobile user identification code of the terminal device changes to ensure the safety of the communication transmission process, the changed temporary mobile user identification code is analyzed and acquired through the pico-base station and then is forwarded to the pico-base station fusion gateway, the pico-base station fusion gateway carries out binding record of the corresponding relation between the temporary mobile user identification code and the pico-base station corresponding to the temporary mobile user identification code and continuously sends the forwarding content to the core network, and because the temporary mobile user identification code does not change every moment, only changes when the mobility management signaling is sent, the recorded corresponding relation can be used in a change period, so that the limitation of the temporary mobile user identification code on the terminal device to receive the non-core network transmission information is temporarily relieved.
Because a plurality of terminal devices can be connected with one pico-base station, one pico-base station can correspond to a plurality of temporary mobile user identification codes, each temporary mobile user identification code corresponds to one terminal device, and when mobility management signaling occurs, all temporary mobile user identification codes of all access terminal devices in the pico-base station need to be recorded and updated.
According to the method provided by the embodiment, a broadcast request is acquired through a pico-base fusion gateway, wherein the broadcast request comprises a broadcast area and broadcast content; the pico-base station fusion gateway determines the pico-base stations existing in the broadcasting area as target pico-base stations according to the broadcasting request; the pico-base station fusion gateway transmits the broadcast content to the means on the terminal equipment corresponding to the temporary mobile user identification code corresponding to the target pico-base station according to the corresponding relation table of the current target pico-base station and the temporary mobile user identification code TMSI, transmits the broadcast request through the pico-base station fusion gateway, and forwards the broadcast content to the corresponding terminal equipment through the corresponding relation table of the pico-base station and the temporary mobile user identification code recorded by the pico-base station fusion gateway, so that the limitation that the terminal equipment cannot receive transmission information except a core network due to the existence of the temporary mobile user identification code is temporarily relieved, and the purpose that the broadcast content can be transmitted to the corresponding terminal equipment without depending on the core network is achieved.
The regional broadcast method of the present application will be described in detail with reference to a specific embodiment.
Fig. 3 is a schematic flow chart of a regional broadcast method according to an embodiment of the present application. As shown in fig. 3, the method includes:
s301, a leather base station fusion gateway acquires a broadcast request, wherein the broadcast request comprises a broadcast area and broadcast content; the broadcasting content is text broadcasting;
specifically, taking word broadcasting as an example, when a user has a need of sending word broadcasting in batches in a designated area, the word broadcasting and the designated area are converted into communication signaling of a broadcasting request through terminal equipment outside the system, and the communication signaling is sent to a pico-base station convergence gateway through the terminal equipment outside the system.
After the pico-cell convergence gateway receives the communication signaling of the broadcast request, the communication signaling of the broadcast request is analyzed into a broadcast area and broadcast content according to a preset analysis rule, wherein the broadcast area comprises a longitude and latitude coordinate range.
When the user is a factory user and the designated area is a specific building in the factory, the position is confirmed by the following method:
the method comprises the steps that longitude and latitude coordinate ranges of a specific building in a factory are stored in a pico-base station fusion gateway in advance, pico-base stations belonging to the same specific building range are bound in a partition mode in the pico-base station fusion gateway according to the occupied area of the specific building and the distribution position of the pico-base stations installed in the coverage area of the pico-base stations, and therefore when information needs to be forwarded to the specific building, the pico-base station fusion gateway can forward the information to all the pico-base stations belonging to the specific building, and further terminal equipment in the specific building can receive the information through the distributed pico-base stations.
S302, the pico-cell fusion gateway determines the pico-cell existing in the broadcast area as a target pico-cell according to the broadcast request;
specifically, the pico-cell fusion gateway comprises a memory, wherein the memory stores pico-cell equipment information connected with the pico-cell fusion gateway, each pico-cell equipment information comprises longitude and latitude coordinates of an installation position of the pico-cell, after the longitude and latitude coordinate range of a broadcasting area is determined, the pico-cell belonging to the longitude and latitude coordinate range of the broadcasting area is searched from the stored pico-cell equipment information, and the pico-cell belonging to the longitude and latitude coordinate range of the broadcasting area is determined to be a target pico-cell for broadcasting content to be transmitted.
How to determine whether the latitude and longitude coordinates of the installation position of the pico-cell are within the latitude and longitude coordinates of the broadcast area belongs to conventional operation which can be easily expected by a person skilled in the art, and detailed description is omitted in this application.
S303, the pico-cell fusion gateway monitors and acquires a mobility management signaling uploaded by the pico-cell to the core network, wherein the mobility management signaling carries a TMSI (temporary mobile station identifier) so as to establish a connection relationship between the pico-cell and the TMSI;
the mobility management signaling comprises a terminal registration signaling, a terminal position updating signaling and/or a terminal switching signaling;
the temporary mobile subscriber identity is a communication identity specific to the terminal device, so that it is necessary to send relevant change information to the core network whenever the terminal device changes in configuration, only a few possible changes of registration, handover and location update are listed here, but other corresponding changes that are easily conceivable by those skilled in the art are also within the scope of application of the method of the present application, and are not listed here.
Specifically, the pico-base station analyzes new mobile management signaling from the power-on, the new mobile management signaling is carried in the accessed terminal equipment, the temporary mobile user identification codes of the terminal equipment are carried in the mobile management signaling, the temporary mobile user identification codes corresponding to the terminal equipment can be obtained through the analysis of the pico-base station, and the pico-base station fusion gateway has management authority to the pico-base station, so that the temporary mobile user identification codes sent by each pico-base station to the core network can be obtained in the communication signaling transmission process of the management pico-base station and the core network.
S304, the pico-base station fusion gateway stores or updates a corresponding relation table of the target pico-base station and the TMSI according to the connection relation between the TMSI and the pico-base station;
specifically, the pico-cell fusion gateway does not need to bind the corresponding relation between the Temporary Mobile Subscriber Identity (TMSI) and the terminal equipment, and only needs to record the connection relation between the Temporary Mobile Subscriber Identity (TMSI) and the pico-cell.
Because the temporary mobile user identification code changes after the mobile management signaling is sent each time, the temporary mobile user identification code stored before is invalid, the connection relation between the temporary mobile user identification code recorded before and the pico-base station can be deleted after the latest temporary mobile user identification code is recorded by the pico-base station fusion gateway, the problem that the storage amount occupies the storage resource of the pico-base station fusion gateway because the storage amount is too large is avoided, and the searching load of the pico-base station fusion gateway in the process of forwarding the signaling is increased.
The method comprises the steps that after a pico-base station receives a terminal registration signaling, a terminal position updating signaling and/or a terminal switching signaling sent by a terminal device, the signaling is forwarded to a pico-base station convergence gateway, the pico-base station convergence gateway receives the signaling and records temporary mobile subscriber identification codes in the signaling to a corresponding relation table of the corresponding sent pico-base station, the memory occupation can be limited by using the storage number because the updating period of a mobility management signaling is generally short, namely, the storage time of each temporary mobile subscriber identification code is marked when the temporary mobile subscriber identification codes are stored, the pico-base station convergence gateway limits the number of connection relations between the pico-base station and the temporary mobile subscriber identification codes, when one pico-base station exceeds the threshold of the number of the temporary mobile subscriber identification codes, for example, 10 pico-base stations clear the temporary mobile subscriber identification codes stored first according to the storage time sequence, so that the storage occupation space of the temporary mobile subscriber identification codes is limited in a certain range, and system resources are saved.
