Problems solved by technology

[0004] When a terminal requests to remove a certain carrier, the removed carrier may be the carrier currently carrying signaling data. If the access network continues to use this carrier to carry signaling data, the terminal cannot receive signaling data; For a certain carrier, the added carrier may be better than the current carrier carrying signaling data. If this carrier continues to be used to carry signaling data, the efficiency of signaling data transmission will not be high.

Embodiment Construction

[0016] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0017] figure 2 It is a schematic structural diagram of a device for selecting a signaling data bearing carrier according to an embodiment of the present invention. The device is located in an access network, and the device includes: a carrier class division and storage module 10, which is used to determine and save each of the currently available carrier sets of the terminal. The level of the carrier, and when the current available carrier set of the terminal changes, the carrier selection module 20 is triggered; the carrier selection module 20 is used to select the carrier with the highest level from the above-mentioned currently available carrier set as the bearer of the signaling data of the ter...

Abstract

A method and an apparatus for selecting signaling data bearing carriers are disclosed in the present invention. The method for selecting the signaling data bearing carriers includes that: a current available carrier set of a terminal changes (S502); an access network acquires the grade of each carrier in the current available carrier set of the terminal (S504); the access network selects the carrier with the highest grade from the current available carrier set as the bearing carrier of the signaling data for the terminal (S506). With the present invention, when the available carriers for the terminal are increased or deleted, the carrier with the highest grade is timely selected from the current available carrier set of the terminal to substitute for the bearing carrier of the current signaling data, which thereby ensures that the signaling data of the access network can be transmitted accurately and efficiently to the terminal.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for selecting a signaling data bearing carrier. Background technique [0002] Since it is stipulated in the air interface protocol that the fragmented signaling data arriving out of sequence will be discarded, it is required for the signaling data to arrive at the receiving end reliably and without disorder. However, if the signaling data is sent on multiple carriers, such as figure 1 As shown, the signaling fragments are likely to arrive at the receiving end (that is, the terminal) out of order. When the terminal reassembles the signaling fragments, it finds out-of-order data, discards the data, and clears the buffer, resulting in cause data loss. [0003] Therefore, it is necessary to ensure that signaling data is sent on a single carrier in a multi-carrier system. However, in the multi-carrier system with symmetrical forward and reverse links, the c...
