LTE and WLAN interconnecting system and switching method

InactiveCN101841880AMeet business quality requirementsReduce latencyWireless communicationTime delaysCoupling
The invention provides an LTE and WLAN interconnecting system and a switching method; and the system introduces the entity of a virtual base station under an LTE architecture, and accesses the entity into the interface of the LTE as WLAN. On the LTE side, the virtual base station remains transparent relative to the LTE side, and is provided with the functions of a general LTE base station. On the WLAN side, the virtual base station can control the WLAN access point. The switching between the LTE and the WLAN is realized through the virtual base station through a standard X2 interface. A second layer tunneling protocol or an Ethernet tunneling protocol is adopted between the virtual base station and the WLAN access point to realize the transmission and the receiving of data and signaling during the switching process, and the WLAN serves as the bottom layered transmission channel of the data and the signaling of an LTE system. The method has the advantage that for the LTE, the switching process is kept consistent with the LTE switching process, which has very small impact on the traditional LTE. The WLAN is connected with the LTE in a tight coupling way, thereby greatly meeting the business requirement requirements, reducing the time delay caused by system switching, and ensuring the system performance.

Sub-prime automobile sale and finance system

A system to provide automobile financing to individuals with relatively lower credit scores or ratings, or no credit rating, due to lack of credit or lending purchases, that would otherwise only qualify for sub-prime, higher interest loans. Due to the overall system structure, lower rate interest loans can be extended to participants. The system utilizes the auto financing loan applicant's term of employment and/or other employment performance data as the principal credit criteria to qualify the creditworthiness of an applicant versus the applicant's credit score or credit rating. Applicant's driving records are also reviewed as system automobile loan approval credit criteria. Loan applicants provide employment related information and execute a letter of authorization providing the system with authority/rights to contact the applicant's employer to verify said employment information. In order to provide participants with lower interest rates than would otherwise be available through conventional channels, automobiles financed under the system must meet minimum profile criteria, including the year of the auto, the mileage, retail value relative to the wholesale value, and autos financed under the system are covered by extended warranties and have GPS systems installed for asset protection purposes. In utilizing employment term as the principal creditworthiness criteria, the system can to be offered through employers as an employee loyalty reward program.

Uplink semi-persistent scheduling released feedback information sending method

InactiveCN101478371ATroubleshoot sending issuesMake sure to accept the statusError preventionWireless network protocolsTelecommunications
The invention provides a method for transmitting feedback information released by uplink semi-persistent scheduling (SPS), wherein the feedback information of resource release signaling of the uplink SPS, as the feedback information of the physical downlink shared channel, is processed. The invention also provides a method for transmitting feedback information released by SPS, wherein for the same one user terminal, when the resource release signaling of the uplink SPS and the resource release signaling of the downlink SPS are transmitted on the same sub-frame, the sub-frame transmits the resource release signaling of only one type of SPS, and the feedback information of the resource release signaling of the transmitted SPS, as the feedback information of the physical downlink shared channel, is processed. The method for transmitting feedback information released by uplink SPS solves the transmission problem of the feedback information released by uplink SPS and solves the problem of compatibility with the acknowledgement/negative acknowledgement (ACK/NACK) feedback information of existing downlink data, thereby ensuring the receiving stat of the resource release signaling of the uplink SPS, preventing the extra interference and unnecessary decoding error, and further ensuring the system performance.
