Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] method embodiment
[0040] According to an embodiment of the present invention, a transport flow template matching method in an LTE system is provided, which extracts required fields from the IP data packet header, matches them in the Filter linked list one by one, and matches those fields that cannot be matched with the current field Filter is temporarily eliminated, that is, the valid flag of the Filter is invalidated, and then the next field is matched in the remaining Filter, and the Filter that cannot be matched is also temporarily eliminated until the last Filter is left. Under normal circumstances, all fields can be matched in this Filter, and the bearer where the Filter is loca...

The invention discloses a transport stream template coupling method in an LTE (Long Term Evolution) system. The method comprises the following steps: after receiving an IP message, extracting a field which needs coupling; determining an address and PDN with is same as a source IP address of the IP message; coupling each field one by one in a Filter linked list of the PDN, and rejecting an unmatched Filter when coupling a field; if all Filter coupling are not successful, checking whether a default bearer exists a Filter or not, if so, indicating that the IP message can not transmitted, otherwise transmitting the message in the default bearer; if coupling the Filter, transmitting the Filter in a corresponding bearer. By employing a technical scheme of the present invention, a transport stream template coupling rate in the LTE system can be substantially raised. The invention also discloses a Transport stream template coupling apparatus in the LTE system. The apparatus comprises a field extraction module, a PDN determination module, a coupling module and a coupling result analysis module.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular to a transport flow template matching method and device in an LTE (Long Term Evolution, long term evolution) system. Background technique [0002] Compared with 3G technology, LTE adopts a brand-new network architecture, which reduces the number of network elements and the complexity of the signaling process. The response speed of the control plane and the speed of the data plane have also been greatly improved, with the uplink data plane reaching 50M / S and the downlink data plane reaching 100M / S. [0003] For a service, the LTE control plane is responsible for allocating channels, establishing bearers, and establishing a link from UE (User Equipment, user equipment) through eNB (evolved NodeB, evolved base station) to the core network; IP data packets are transmitted on the road. Multiple bearers are usually established between the UE and the core network, and each upl...
