Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
The problem that exists in order to solve prior art, the embodiment of the invention provides a kind of chain processing method, as shown in Figure 1, may further comprise the steps:
Step 101, local terminal obtain the performance parameter of current ascending physical signal link;
Step 102, according to the Link State of the current ascending physical signal link of determination of property parameter;
Step 103, establishment are carried the link detecting frame of link-state information, and are sent to the opposite end by descending physical link; Wherein, the bit number that takies of this link-state information is corresponding to the ascending physical signal number of links of local terminal with the opposite end.
As shown in Figure 2, take many physical link the transmission of datas by a logical links between local terminal and the opposite end, every physical link can be divided into descending physical link and descending physical link.Wherein, local terminal can only detect the opposite end by the transfer of data situation of ascending physical signal link transmission to local terminal, and can't know in time that local terminal sends to the transfer of data situation of opposite end by descending physical link.Wherein any physical link breaks down, and will affect the overall data transmission situation between local terminal and the opposite end.To this, the method that the embodiment of the invention provides is by adding link-state information in the link detecting frame that transmits and carry out physical link by this link detecting frame and detect between local terminal and opposite end, so that the operating state of link all can be in time known at two ends.
Concrete, local terminal is built logical links according to pre-configured basic physical slot by time and opposite end, and this logical links is corresponding to one or more ascending physical signal link and described descending physical link.Logical links carries out transfer of data after setting up and finishing between local terminal and the opposite end, for example set up logical links between base station controller and the base station transceiver after, when this base station controller was local terminal, base station transceiver was the opposite end; When base station transceiver was local terminal, base station controller was the opposite end.For fear of the operational failure link transmission data, local terminal starts the link detecting function, obtains the performance parameter of local terminal current physical layer and link layer; Wherein, local terminal periodically starts the link detecting function, also can be in real time or this link detecting function of start by set date.Performance parameter comprises: physical layer CRC (Cyclic Redundancy Check, cyclic redundancy check (CRC) code) mistake number, link layer retransmission frame number and frame-skipping number.
After getting access to performance parameter, this performance parameter and preset parameter threshold value are compared, determine the Link State of current ascending physical signal link according to comparative result, concrete condition is as follows:
When the Link State of (1) determining current ascending physical signal link is faulty link, close the transmission time slot of current ascending physical signal link, the length of adjusting the link detecting frame that sends to the opposite end is the presumptive test byte number, and sends to the opposite end by descending physical link.Link detecting frame after the adjustment length carries link-state information.
Wherein, because the original length of link detecting frame is too short, in the situation that the error rate is low, difficulty detects the link condition variation, and therefore, this presumptive test byte number is more, is good so that detect link failure, such as 200 joint numbers.As shown in Figure 3, the original length of this link detecting frame that the embodiment of the invention provides is 3 bytes, comprising: frame type, frame length and link-state information.The bit number that the link-state information of this link detecting frame takies is corresponding to the ascending physical signal number of links of local terminal with the opposite end, for example have 8 physical links between local terminal and the opposite end, the byte number that this link-state information takies is 1, comprise 8 bit (bit), the state of a physical link of each bit sign.When being normal link according to the current ascending physical signal link of determination of property parameter, fill in 0 at the bit that this ascending physical signal link is corresponding; When determining that current ascending physical signal link is faulty link, fill in 1 at the bit that this ascending physical signal link is corresponding.And, when up physical link is normal link before deserving, can carry the data message of N byte after this link-state information, wherein N is positive integer.
When local terminal is base station controller, when the Link State of determining current ascending physical signal link is faulty link, can also detect whether available free resource of service resources pond corresponding to other ascending physical signal links, if available free resource, the business datum that current ascending physical signal link is being transmitted is switched to idle ascending physical signal link.
