Disclosed is a rapid and facilitated method of producing from a parentlal template polynucleotide, a set of mutagenized progeny polynculeotides whereby at each original codon position there is produced at least one substitute codon encoding each of the 20 naturally encoded amino acids. Accordingly, there is also provided a method of producing from a parental template polypeptide, a set of mutagenized progeny polypeptides wherein each of the 20 naturally encoded amino acids is represented at each original amino acid position. The method provided is termed site-saturation mutagenesis, or simply saturation mutagenesis, and can be used in combination with other mutagenization processes, such as, for example, a process wherein two or more related polynucleotides are introduced into a suitable host cell such that a hybrid polynucleotide is generated by recombination and reductive reassortment. Also provided are vector and expression vehicles incuding such polynucleotides, polypeptides expressed by the hybrid polynucleotides and a method for screening for hybrid polypeptides.

The invention discloses a macro eNB and small cell eNB collaboration method and a device thereof. When a terminal which resides in a macrocell and is in an idle state satisfies triggering conditions, a union connection establishment request is initiated to a macro eNB corresponding to the macrocell; when the union connection establishment is finished, the macro eNB informs a mobile management entity of a small cell eNB which is selected for the terminal and is corresponding to a mini-cell ; the mobile management entity deletes a user plane bearing between the macro eNB and a signaling gateway, establishes a user plane bearing between the small cell eNB and the signaling gateway and controls the macro eNB and the small cell eNB to respectively complete initial context establishment; the terminal completes connection reassortment according to wireless configuration information obtained from the macro eNB; and transceiving of control plane signaling between the terminal and the mobile management entity is carried out through the macro eNB, and transceiving of user plane data between the terminal and the signaling gateway is carried out through random access in the mini-cell. With the application of the above scheme, reasonable collaboration between the macro eNB and the small cell eNB can be realized.

The invention provides a half-static scheduling reassortment method and system; the method comprises the following steps: calculating a half-static scheduling reassortment period in half-static scheduling now construction; carrying out half-static period scheduling according to the half-static scheduling reassortment period; calculating transmitted data amount when a user terminal reaches the half-static scheduling reassortment period; determining whether to start a half-static scheduling reassortment activate authorization or not according to a relation between the transmitted data amount, a MCS lowering threshold, an error rate threshold and a PRB lowering threshold. The method and system consider delay demands of different business periods, and no resource predistribution processing is needed, thus reducing processing amount cost, and greatly reducing DSP processing time.

The invention discloses an influenza A virus Vero cell adapted strain and application thereof.

The invention discloses a relocation method of wideband code division multiple access systems; wherein, by carrying a directional retrial cell in wireless bearing assignment response information and carrying the directional retrial cell and target district information of a wireless network controller in relocation application information, eHSPA Node B informs a core network to carry out the relocation from the eHSPA Node B to the wireless network controller when the core network carries out the circuit switching service. The invention can effectively realize the relocation as well as the establishment of CS service between the eHSPA Node B and RNC and has good compatibility for traditional protocols, therefore, the present RNC protocol and RNC need not be modified at all; in addition, the relocation method reduces the time of service establishment and the times of gap reassortment, thus reducing the risk of call drop caused by the gap reassortment.

The invention discloses a configuration method and a system of a backhaul link resource in wireless resource reassortment. The upper layer network node of an access point (AP) confirms the configuration information which is sent to the AP and is included in the backhaul link resource reassortment according to whether the spectrum resource which is used for allocating the backhaul link resource for the AP and the spectrum resource of the current access link of the AP are the same. The AP conducts resource reassortment according to the configuration information of the backhaul link resource in the wireless resource reassortment order after receiving an order of the backhaul link resource reassortment. The invention further discloses a configuration system of the backhaul link resource in the wireless resource reassortment. By means of the configuration method and the system of the backhaul link resource in the wireless resource reassortment, the problems that the resource reassortment of the backhaul link is still not clear and the how to configurate a backhaul link subframe of an existing art can be solved.

The invention provides a lead code form reassortment method and a lead code form reassortment system for a cognitive radio system. The method comprises that when a base station reassorts spectrum resources, whether a lead code form in a random access progress of a terminal needs to be reassorted is judged; and when the lead code form needs to be assorted, the base station can send lead code form assortment information to the terminal. After the base station reassorts the spectrum resources, when it is determined that the lead code form needs reassorting, the lead code form is then reassorted. Thus, the purpose of flexibly assorting lead code forms according to spectrum resources is achieved. Especially, when the frequency points of the spectrum resources needing to be reassorted are low, the lead code form can be reassorted with the short code length. Therefore, time frequency resources are saved, and resource utilization rate is improved.

The invention provides an indication method of a radio network controller-identification (RNC-ID) analytic mode, comprising the following steps: an RNC sends out a broadcasting signaling with a section ID cell and the indication of the RNC-ID analytic mode to UE; the UE adopts the radio source control connection to access the RNC-ID analytic mode indicated by the section broadcasting signaling as a local RNC-ID analytic mode in the process of establishing a radio source control connection; a destination RNC sends out a downlink reassortment signaling with a new U-RNTI and the indication of a new RNC-ID analytic mode to the UE; and the UE adopts the new RNC-ID analytic mode indicated by the downlink reassortment signaling as the local RNC-ID analytic mode in the process of adopting the new U-RNTI to set relocation or inter-system switching. The invention can confirm the RNC-ID analytic mode in a mobile communication system to further reduce the call drop rate.
