Embodiment Construction
[0058] The present invention is based on the specific realization of the ad hoc network spreading code distribution method of time division synchronous code division multiple access including the following steps:
[0059] Step 1: Spreading code OVSF application stage: by exchanging messages on the public control channel and formulating codeword search rules to complete the allocation of spreading codes to new users;
[0060] The second step: the OVSF redistribution stage of the spreading code: redistribute the codewords that generate code blocking;
[0061] Step 3: Spreading code OVSF maintenance stage: By means of exchanging messages on the public control channel, update the spreading code tree information stored by each node;
[0062] Step 4: Spreading code OVSF release stage: according to the spreading code tree, correspondingly release the occupied codeword and its parent code and child code.
[0063] After the network nodes in the self-organizing network based on the TD-...
