The method comprises the following steps: (1) adding titanium alkoxide, silicon alkoxide, dihydric alcohol and metal co-catalyst into the solvent and conducting the reaction at a temperature of about 80° C. to 180° C., then removing the unreacted materials and small molecular products in the reaction system; (2) adding complexing agent into the reaction system, then collecting catalyst from the products obtained in this step. Moreover, the method may comprises steps of: (1) adding titanium alkoxide, dihydric alcohol and metal co-catalyst into the solvent and conducting the reaction at a temperature of about 80° C. to 180° C., then removing the unreacted materials and small molecular products in the reaction system; (2) adding silicon alkoxide and complexing agent into the reaction system, then collecting catalyst from the products obtained in this step. The catalyst in the present invention has higher activity and thus the catalyst additional amount is reduced which will improve the quality of the products. Moreover, the catalyst in the present invention could be used alone in the production of PBS or its copolyester without the need for other materials and it won't react with water and thus could be stored for a long time. In sum, the catalyst in the present invention has a broad prospect in industrial application.

摘要： During inter-radio access technology (IRAT) handover between LTE and eHRPD technologies, Internet protocol (IP) service continuity at a user equipment (UE) may be maintained. Thus, a method, an apparatus, and a computer program product are provided for maintaining the IP service continuity during IRAT handover from an SRAT to a TRAT within an evolved packet core (EPC)—capable region. The apparatus attempts to transfer an EPC context to a TRAT, determines that a failure occurs when attempting to transfer the EPC context to the TRAT, and attempts to maintain at least one IP service continuity within the EPC context according to the failure. The attempt to maintain may include an attempt to maintain an entire EPC context or a set of parameters including at least one of an IP address, a domain name system (DNS) address, a proxy call session control function (P-CSCF) address, or a quality of service (QoS).
