Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, the present invention at first merges the transmission time slot of 3G network and the transmission time slot of 2G network, intercept employed time slot between base station controller (RNC) and the base station (Node B) then, by the time slot that listens to, adopt Bootstrap Protocol (BOOTP) mode to set up maintenance channel based on IPOA by Node B.
As shown in Figure 3, the present invention need dispose an external time slot intersection equipment (DACS) at the uplink direction of 2G network base station (BTS) and 3G network base station (Node B), this external time slot intersection equipment merges to the E1/T1 time slot of 2G network and the E1/T1 time slot of 3G network on the E1/T1, thereby realizes the transmission time slot of 3G network and 2G network sharing E 1/T1.External time slot intersection equipment has 3 E1/T1 ports at least, a port that connects 3G, a port that connects 2G, the 3rd port for output.Intersect equipment by external time slot, can set E1/T1 time slot that 3G network takies in certain scope.
As Fig. 4, shown in Figure 5,2G network base station equipment or 3G network base station equipment can be finished time slot intersection pooling function equally.
Set up physical layer by E1/T1 between Node B and the RNC and be connected, physical connection is based on Fractional ATM mode, and Fractional ATM mode requires Node B and the separate employed E1/T1 time slot of configuration of RNC.When adopting this mode, if there is not data file, Node B can't listen to RNC and use which time slot.
Time slot intersection equipment can pass through Timeslot cross function, discrete time slot packed format is unified, reduce the time slot format combination, in actual networking, the number of Node B base station has hundreds and thousands of usually, and each Node B base station can utilize time slot intersection equipment that its shared E1/T1 time slot is set.For example BTS takies 1-15 the time slot of its input E1, and Node B also takies 1-15 the time slot of its input E1, then the E1 mouth that connects Node B can be configured to use the 17-31 time slot by time slot intersection equipment, can not cause time slot collision like this on output E1.
Time slot intersection equipment can pass through Timeslot cross function, discrete time slot packed format is unified, reduce the time slot format combination, after finishing the construction of the network planning and physical equipment, the mode that all Node B in the network is taken the E1 time slot is combined into a time slot combination table, by certain mode this time slot combination table is notified to all Node B.Node B by time slot combination table that actual networking is used just intercept can with the connecting of RNC, thereby quickened the process of setting up of maintenance link greatly.The time slot combination table is notified to the mode that all Node B can adopt the near-end data to download, also can adopts predefined mode before delivery is installed in Node B base station.
Illustrate the method that time slot combination table that Node B uses actual networking is intercepted below.
When carrying out the port snooping of Fractional ATM mode, if be to be connected by the physical layer that E1 sets up between Node B and the RNC, following table is that all Node B take the time slot combination table that the mode of E1 time slot is formed:
{0Xfffe，0x2FFFE，0x7FFE，0x6FFFE，0x3FFE，0xEFFFE，0x1FFE，0x1EFFFE，0xFFE，0x3EFFFE，0x7FE，0x7EFFFE，0x3FE，0xFEFFFE，0x1FEFFFE，0x3FEFFFE，0x7FEFFFE，0xFFEFFFE，0x1FFEFFFE，0x3FFEFFFE，0x7FFEFFFE，0xFFFEFFF?E，0x1FE，0xFE，0x7E，0x3E，0x1E，0xE，0x6，0x2}；
Node B is fixed as 1～15 time slot according to the Fractional atm port of 15 time slots of above-mentioned time slot combination table elder generation's configuration, initiates BOOTP (Bootstrap Protocol) request with the forms of broadcasting to RNC then, attempts the response that whether can receive RNC.If it is unsuccessful, the Fractional atm port of 16 time slots of configuration, because 0 time slot and 16 time slots are system's reserved time slots, therefore the Fractional atm port of 16 time slots is fixed as the 1-15+17 time slot, start BOOTP then and attempt, attempt 30 kinds of slotted modes successively and promptly can intercept out RNC and used which time slot.In order to attempt most possible slotted mode earlier, it is as follows to attempt order:
15，16，14，17，13，18，12，19，11，20，10，21，9，22，23，24，25，26，27，28，29，30，8，7，6，5，4，3，2，1
Each hexadecimal number is used for representing that a kind of time slot intercepts mode in the time slot combination table, the time slot that " 1 " representative in its corresponding binary number will be intercepted, 0 time slot of the rightest low bit representation E1 of binary number.For example the binary number of 0xFFFE correspondence is 1,111 1,111 1,111 1110, and the time slot that expression need be intercepted is 1～15 time slot.The binary number of 0x2FFFE correspondence is the 1-15+17 time slot that E1 is intercepted in 0,010 1,111 1,111 1,111 1110 expression.
When carrying out the port snooping of Fractional ATM mode, if be to be connected by the physical layer that T1 sets up between Node B and the RNC, following table is that all Node B take the time slot combination table that the mode of T1 time slot is formed:
{0x7FFF，0xFFFF，0x3FFF，0x1FFFF，0x1FFF，0x3FFFF，0xFFF，0x7FFFF，0x7FF，0xFFFFF，0x3FF，0x1FFFFF，0x1FF，0x3FFFFF，0x7FFFFF，0xFFFFFF，0xFF，0x7F，0x3F，0x1F，0xF，0x7，0x3，0x1}；
Node B is the Fractional atm port of 15 time slots of configuration earlier, is fixed as 0～14 time slot, initiates BOOTP (Bootstrap Protocol) request with the forms of broadcasting to RNC then, attempts the response that whether can receive RNC.If unsuccessful, the Fractional atm port of 16 time slots of configuration is fixed as the 0-15 time slot, starts BOOTP then and attempts, and attempts 24 kinds of slotted modes successively and promptly can intercept out RNC and used which time slot.In order to attempt most possible slotted mode earlier, it is as follows to attempt order:
15，16，14，17，13，18，12，19，11，20，10，21，9，22，23，24，8，7，6，5，4，3，2，1。
Each hexadecimal number is used for representing that a kind of time slot intercepts mode in the time slot combination table, the time slot that " 1 " representative in its corresponding binary number will be intercepted, 0 time slot of the rightest low bit representation T1 of binary number.For example the binary number of 0x7FFF correspondence is 0,111 1,111 1,111 1111, and the time slot that expression need be intercepted is 0～14 time slot.The binary number of 0xFFFF correspondence is 0～15 time slot that T1 is intercepted in 1,111 1,111 1,111 1111 expressions.
Transmit employed time slot by carrying out lub between the RNC that listens to and the Node B, initiate Bootstrap Protocol (BOOTP) request by Node B with broadcast mode, communicate that request to RNC, RNC delivers to the centralized operation maintenance console to this BOOTP request package, and guarantee that it is the request which Node B sends that the centralized operation maintenance console can be discerned this BOOTP request package, thereby give its distributing IP address.If therefore the centralized operation maintenance console is the outside at RNC, so just need Node B that the BOOTP request package is done some processing, the information that for example adds this base station of expression in the client hardware address of BOOTP request package can be discerned this BOOTP request package and from which Node B send to guarantee outside centralized operation maintenance console.The BOOTP response that will guarantee the response of centralized operation maintenance console in addition can be returned Node B side, thereby obtain the centralized operation maintenance console and give Node B IP address allocated, Node B creates the IPOA passage according to IP address that obtains and the time slot that listens to, thereby finishes the foundation based on the maintenance channel of IPOA between Node B and the RNC.
Carry out lub between RNC and the Node B and transmit the mode of employed time slot except intercepting out according to time slot packed format table by Node B, Node B can also use a special time slot packed format table, this combination comprises 30 available single time slots of E1, or available 24 single time slots of T1.This method only need be reserved the request of intercepting that a single time slot is used to monitor Node B in advance at the RNC end, maximum 30 trials of Node B process under the E1 mode just can listen to the time slot communication port with RNC, under the T1 mode through attempting just can listening to the time slot communication port with RNC for maximum 24 times, as long as can listen to single time slot port, Node B just can send the BOOTP request to RNC by the single time slot port that listens to, this request is sent to RNC, RNC delivers to the centralized operation maintenance console to this BOOTP request package, give Node B distributing IP address by the centralized operation maintenance console, Node B creates the IPOA passage according to the IP address that obtains on single time slot passage, thereby finishes the foundation based on the interim maintenance channel of IPOA between Node B and the RNC.RNC sends Node B to by time slot data and other configuration files that this temporary IP OA maintenance channel uses actual networking, Node B just can create formal IPOA passage according to time slot data and the configuration file received, thereby finishes the foundation based on the maintenance channel of IPOA between Node B and the RNC.
After successfully setting up the IPOA maintenance link, Node B regularly carries out the ping operation to RNC, and whether monitor the IPOA link has chain rupture.Ping operation is to check bag by send IP on the IPOA link, and checks that the response of whether receiving destination judges whether normal method of link.If chain rupture is arranged then directly utilize the Fractional ATM timeslot number listened to set up BOOTP and call out, need not carry out the trial of time slot format more again.
Below only the present invention will be described with preferred embodiment, and those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
