Abstract
The invention forwards a method for detecting the transmitting the ring network of the base station, which includes the following steps. The controller of the base station sends a massage of transmission-detection. If receiving the massage, the station shows that the transmission of uplink works in a normal state, and the updated massage is sent to the downlink equipment. If not receiving the massage in the preset time, the station triggers a downlink level transmission-detection and sets the working state of uplink to be unmoral. This invention runs a loop detection and anti-loop detection simultaneously in the ring network, and each base station can obtains the transmission link status simultaneously, to avoid inconsistent transmitting massages by different station. The link detection does not involve a number of logic levels, thus the detection speed is very rapid.
Description

The networking mode of base stations in mobile communication system mainly contains: star-like, chain, tree type and ring-like four kinds.Star-like networking mode is realized fairly simple, and reliability is higher, but takies more port and transfer resource; The chain networking mode can be saved transmission and port resource, but very high to the reliability requirement of transfer resource, in case the transmission chain rupture, a plurality of base stations will be affected, and can not provide professional; Chain is actually special tree group network, can save port and transfer resource, but reliability can't ensure.
Under some special occasions, when cellular system is served the very high occasion of safety or reliability requirement, require system can continually provide professional, even require in some unusual situations, such as the transmission chain rupture etc., also require ongoing business not interrupt; Often adopt the ring-shaped network mode this moment, and the base station joins end to end by two links and forms a ring in the ring-shaped network, and the benefit of ring-shaped network mode is in the situation of local transmission chain rupture, and the base station still can provide service.
In order to realize that the ring-shaped network transmission is interrupted but business is not interrupted, must detect transmission link in time.With the gsm system is example, existing GSM base station ring-shaped network depends on OML (the Operation Maintainence Link between base station and the base station controller, Operation and maintenance link) transmitting chain rupture detects, and the independent OML link that oneself is all arranged between each base station and the base station controller, thus the OML link between each base station and base station controller transmission link is detected is separate.
But, adopt OML link detecting transmission chain rupture to have following deficiency:
1, the OML link adopts multilayer communication protocol realization between communication system entity, transmission of information needs the time between the entity interior layer, and the overwhelming majority of transmitting on the OML link is Operation and Maintenance information rather than link detecting information, thereby blunt to transmission chain rupture detection, and efficient is not high;
2, own independent O ML link is all arranged between each base station and the base station controller, each link all detects carrying out chain rupture, because link entity state machine more complicated, thereby the chain rupture difference on opportunity that each OML link detecting arrives when causing transmitting chain rupture;
3, carried relevant base station all operations were maintenance information on the OML link, the OML chain rupture represents that namely base station and base station controller are out of touch, thus adopt the OML link transmit chain rupture detect be difficult to accomplish with the base station operation maintenance function independent;
4, there are close ties between OML link and the BTS service, as: base station configuration and cell attribute all are to be issued to the base station by OML from base station controller, also have close ties between transmission chain rupture and the BTS service; Therefore, adopt OML link detecting transmission chain rupture to be difficult to accomplish with business independent.

Description of drawings
Fig. 1 is an embodiment of the invention base station annular networking schematic diagram.
Embodiment
Core concept of the present invention is: base station controller sends the transmission detect-message, the normal and unusual of higher level's span line indicated according to the situation of receiving message in the base station, and continue to send detect-message to next stage base station or base station controller, to finish the detection of whole ring-shaped network.
Below in conjunction with specific embodiments and the drawings the present invention is further specified.
Fig. 1 is an embodiment of the invention base station annular networking schematic diagram, as shown in the figure, base station 1-〉base station 2-〉base station 3-〉base station 4 forms and just encircling networking, base station 4-〉base station 3-〉base station 2-〉base station 1 forms the networking of anti-ring.Just encircling and instead encircling in the networking 5 span lines are being arranged respectively.
The course of work of present embodiment is specific as follows:
The first interface of base station controller is responsible for just encircling the transmission detection of networking in the present embodiment, and the transmission that second interface is responsible for the anti-ring networking detects.So the base station controller first interface is just encircling networking direction transmission transmission detect-message, base station controller second interface sends the transmission detect-message in anti-ring networking direction.
The transmission of transmission detect-message is periodically to carry out, and the transfer resource of this message arranges, and for example: present embodiment is with certain time slot among the E1 or sub-slots transmission detect-message.Preferably, the transmission detect-message can comprise following field: transmission detect-message identifier Transmission_Detect_Message_ID, just encircle each span line status indication Transmission_Foward_Segments_Status_Mark, each span line status indication Transmission_Backward_Segments_Status_Mark of anti-ring, check (CRC).Wherein, just encircling the transmission state that each span line status indication Transmission_Foward_Segments_Status_Mark record is just encircling each span line, for example, if it is all normal just to encircle 5 span lines, then its value is: 11111.Equally, the transmission state of each each span line of span line status indication Transmission_Backward_Segments_Status_Mark record anti-ring of anti-ring.
If the transmission detect-message is received in step 2 base station, be normal at the mid-upper level span line of described transmission detect-message state then, and send transmission detect-message after upgrading to next stage equipment; If the base station can not receive the transmission detect-message in the given time, then trigger to next stage equipment and send the transmission detect-message, and be set up one-level span line state for unusual.
For example, as shown in Figure 1, if the transmission detect-message of just encircling is received in base station 1, then at mid-span line 1 state that just encircling in each span line transmission state mark of this transmission detect-message for normal (in the present embodiment, normal with " 1 " expression, " 0 " expression is unusual).Simultaneously, the value of this transmission detect-message mid-base station 1 anti-ring upper level span line state, namely the state value of anti-ring span line 4 is the state value of anti-ring span line 4 in the transmission detect-message on the upper anti-ring received of base station 1.Then, the transmission detect-message after base station 1 is upgraded to the transmission of next stage equipment is just being encircled on the networking direction, and base station 2 is the next stage equipment of base station 1.
If base station 1 can not receive the transmission detect-message of just encircling within the predetermined time, think that then span line 1 is unusual, the 2 transmission transmission detect-message to the base station are triggered in base station 1, and put and just encircle in each span line transmission state mark span line 1 state for unusual, the correlation in the transmission detect-message that sends on the upper anti-ring that the value of each span line transmission state mark of anti-ring and anti-ring transmission state is still received for base station 1 in this message.
Similarly, if the transmission detect-message on the anti-ring is received in the base station, be normal at the mid-anti-ring upper level of described transmission detect-message span line state then, and the transmission detect-message after send upgrading to anti-ring next stage equipment, the value of just encircling upper level span line state of base station described in this message is the correlation in the upper transmission detect-message of just encircling received of base station; If the base station can not receive the transmission detect-message on the anti-ring direction in the given time, then trigger to anti-ring next stage equipment and send the transmission detect-message, be unusual at the mid-anti-ring upper level of message span line state, the correlation in the upper transmission detect-message of just encircling upper transmission that the value of just encircling each span line transmission state and anti-ring transmission state in this message is still received for the base station.
The next stage equipment of base station also may be base station controller.For example, be exactly base station controller at the next stage equipment that just encircles base station 4 on the networking direction.If second interface of base station controller receives the transmission detect-message of just encircling that base station 4 sends, then put and just encircling in each span line transmission state mark span line 5 states in the message for normal; If second interface of base station controller can not receive the transmission detect-message of just encircling, then record is just encircling in each span line transmission state mark span line 5 states for unusual.
Be specially: the base station controller first interface obtains and just encircles the networking situation according to just encircling each span line state value in the transmission detect-message of receiving, and upgrades the just ring transmission state value in the transmission detect-message; Base station controller second interface is according to the anti-ring networking situation of obtaining of each span line state of anti-ring in the transmission detect-message of receiving, and the anti-ring transmission state value in the renewal transmission detect-message.
For example, thresholding is as follows in the transmission detect-message received of base station controller first interface:
| Transmission_Foward_Segments_Status_Mark | 10111 |
| Transmission_Backward_Segments_Status_Mark | 10111 |
Then the base station controller first interface judges that just encircling span line 2 interrupts;
Thresholding is as follows in the transmission detect-message that base station controller second interface is received:
| Transmission_Foward_Segments_Status_Mark | 10111 |
| Transmission_Backward_Segments_Status_Mark | 10111 |
Then base station controller second interface judges that anti-ring span line 2 interrupts.
Therefore, base station 1 just is operated in to be encircled, and namely is connected to the base station controller first interface, base station 4 is operated in anti-ring, namely be connected to base station controller second interface, base station 2, base station 3 can not just be encircled and be connected to the base station controller first interface, can not anti-ring be connected to base station controller second interface.
Preferably, the transmission detect-message can also comprise field: just encircling transmission state Transmission_Foward_Status and anti-ring transmission state Transmission_Backward_Status.
After base station controller first interface and base station controller second interface obtain transmitting the result of detection, more encircle the Transmission_Foward_Status in the transmission detect-message that periodically sends on direction and the anti-ring direction, the value of Transmission_Backward_Status the first month of the lunar year.The value of Transmission_Foward_Status is used for expression and is just encircling the networking transmission state, for example, the transmission fault of 4 of the transmission fault, base station controller first interface of 3 of transmission fault with 2 of 1,2,3,4 transmission faults of representing 1 of base station controller first interface and base station respectively, base station controller first interface and base stations, base station controller first interface and base stations and base stations can be set, and it is normal to represent just to encircle the networking transmission with 0.Same, Transmission_Backward_Status is used for representing the anti-networking transmission state that encircles, for example, the transmission fault of 4 of the transmission fault, base station controller second interface of 3 of transmission fault with 2 of 1,2,3,4 transmission faults of representing 1 of base station controller second interface and base station respectively, base station controller second interface and base stations, base station controller second interface and base stations and base stations can be set, represent that with 0 counter to encircle the networking transmission normal.
In sum, the present invention adopts the work of two base station controller interface start detection, and an interface is responsible for just encircling the transmission detection of networking, and the transmission that another interface is responsible for the anti-ring networking detects, and the ring-shaped network transmission is detected become simple.Detect link among the present invention and do not relate to a plurality of logical levels, thereby detection speed is very fast, and, detect link and be independent of the OML link, so that the business function of the Operation and Maintenance function of transmission measuring ability and base station and base station keeps independent.
Suppose that distributing to the bandwidth of transmitting detection is 64Kbps, every the transmission detect-message is 10 Bytes, then the transmission delay of every transmission detect-message is 1.25MS (10 * 8/64000=0.00125S=1.25MS), each base station is the propagation delay time 3.75MS (leaving surplus) of 3 times of transmission detect-message to the processing delay of transmission detect-message, the maximum transmission cycle of then transmitting detect-message can reach 5MS (can not have transmission detect-message congestion phenomenon on the link), 20 transmission detect-message are filtered after the smoothing processing sampling and once (are left surplus) and just carrying out annular networking, the anti-ring decision-making is then transmitted detection sensitivity and can be reached 100MS.More than transmit tens of seconds of detection highly sensitive by the OML link.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
