The wireless communication system far-end radiofrequency unit software upgrading method

technical field

The invention relates to wireless communication system for upgrading method of software, to wireless communication system with the far-end radiofrequency unit software upgrading method. Background technology system structure development's tendency is: Separation radiofrequency unit and a control unit; and optical fibre or cable) are connected by the remote transmission method, wherein a placing the radiofrequency unit of the lower seat. The device for construction's power is divided into two opposite the independent parts end of the integral system and independently developed, multiple radiofrequency unit the common base control unit. Not only reduced the charging, moreover enhanced of the flexible and covering rate, simultaneously with facilitated engineering and. Two parts of here the input of called a battery unit (BBU) and far-end radiofrequency unit (RRU) are. The RRU of groove are multiple and varied, a link of things, annular network, time of equal, therefore the normal working of each RRU or not to affect with units are connected with thereof. The maintenance communication device (a software upgrading) is outer surface of the integral system. A RRU, wherein the locating position is generally not easy to firmly, wherein maintenance is usually conducted by a BBU, therefore the maintenance difficulty of the. , And how to ensuring consistency between datum of RRU of, reliable stable and fast updating is a key technology of the far-end device of. Invention content to solve the upside of prior process and insufficient, the volume of the invention provides is in wireless communication system and far-end radiofrequency unit software upgrading method, a ensuring consistency between datum to RRU is connected with, reliable stable and fast updating. In turn to serve the invention key, the invention realizes to that: The wireless communication system and far-end radiofrequency unit software upgrading method, comprising; (1) far-end radiofrequency unit is mounted in the internal memory the current an optical interface module, software and reporting the soft pole number of the light interface module software to the base main unit; (2) And a main unit according to far-end radiofrequency unit and Software pole number of optical interface module software of optical interface module software's the need to upgrading; and light interface module software need to upgrading; and far-end radiofrequency unit downloads the new pole from the base main unit the optical interface module, software and preserving the internal memory load, andA no need to invention, a step; ended(3) In communication connection with a far-end radiofrequency unit detection optical interface is a hose, a normal; and light interface module software upgrading successfully, is a hose, and a far-end radiofrequency unit and load the cutting an optical interface module software.

And a step further, wherein the step (1) is concretely: (11) Is a far-end radiofrequency unit, an operation the start-up program, a load current light interface module software from the internal memory; (12) Is a far-end radiofrequency unit and a main unit information are arranged, a far-end radiofrequency unit for obtaining connection advanced software from the base main unit and load, and(13) For upgrading of far-end radiofrequency unit of optical interface module symbolized software, a upgrading suitable for upgrading state; and alarming reporting, wherein the upgrade code to form a hose, the finished,And the upgrade rate is a hose and reporting, the optical interface module Software version for the base main unit comprises a far-end radiofrequency unit. Compares the existing technology, the invention realizes, reliable stable and fast updating of RRU, reduced multiple RRU relative to obtain prolonging network flow from BBU the optical interface module software, a winding has a condition of the RRU optical interface module software with problems the upgrade, the soft returned to automatically roll, which are not interfere with the operation of the lower RRU. Auxiliary digital instructional diagram l is a current position of invention. Digital 2 is in RRU of start-up the optical interface module the load current. Digital 3 is in RRU connection advanced software the optical interface module the load current. The detailed description of illustrated embodiments following to the further detail to the invention claims a light of the auxiliary digital. The invention is applied in upgrading of far-end base station. Usually and ensure the layer and lower RRU of the optical interface module of RRU completes through an optical fibre BBU and reliable communication. And the optical interface module software is usually with large, and multiple RRU possibly is opened;; and therefore RRU switch, possibly with the network is busy to the BBU request software, the BBU load gain; therefore is the optical interface module and RRU internal memory, only of need to upgrading time obtaining novel version software from BBU. Deposited a text document on the RRU memory, a invention RruSwVer.ini. The file is put in the optical interface module software's upgrading state, and reading for connection advanced software and a software. For example, the upgrade mark of each software and define to that: typedef struct tagOsmCfgParamStrucOSS-CHAR szName (20); /* Software name */OSS-CHAR; szFlag /* 'The, */

OSS-CHAR; szValue /* “0 " Unit the normal; and, 1 ' And szEnd for upgrading state */OSS DEGREES; /* Of \ n shape */} T0amCfgParam, *PT0amCfgParam; Image l is current position of invention. Shown and a digital 1, wherein the invention includes the following steps: (A) RRU of loads on the internal memory the current an optical interface module software, then unequal BBU and corresponding is normal. (B) RRU to the soft pole number of BBU and optical interface module; The pole number of optical interface module of software BBU according to and lower present invention and inform RRU. a (c) and optical interface module software need to invention, and RRU obtaining software from BBU; Otherwise jumper over a software upgrading of directly stretches to the following starting switch. The soft (d) RRU to obtain preserves) and temporary version memory and loads and. a (e) and optical interface module software and failure; and RRU reset and mounted in the cutting software, realizing software is connected to a rolling. Digital 2 is in RRU of start-up the optical interface module the load current. Digital 3 is in RRU connection advanced software the optical interface module the load current. A RRU of are divided into a CPU software and optical module, software two module software and are on different hardware, a reset does not interfere with other work. Digital 2 shown and a digital 3, And follows- (i) is a RRU, the first operation the start-up program, a start-up program of takes for bearing the current light interface module software from the memory. The information between the link (II) RRU BBU and arranged, obtaining connection advanced software from BBU (the CPU software) and loads and. of the checking door) connection advanced software, and output interface module software upgrading code, a upgrading suitable for upgrading state, and reporting integrated an emergency, wherein a symbolize is provided with a normal and jumper or a software upgrading flow. (Iv) RRU connection advanced software to BBU and optical interface module Software thereof; numberBBU according to pole number of optical interface module of software and lower present invention and inform RRU. a (v) and optical interface module software need to invention, and RRU preserves on from the BBU gain software and used temporary version memory, a first of the corresponding downloading software suitable for upgrading state, a load operation the new an optical interface module software. (Vi) RRU connection advanced automatic detection optical fibre component is a normal. And the second 30 bests the communication link on optical fibre is unusual; and thinks of the optical interface module software and failure, and RRU; restartsOtherwise according thinks software upgrading successfully, a casing the following working.
