    Abstract: This invention discloses a control method of a single-frequency network and a control entity of a single-frequency network. The control method of the single-frequency network provided by this invention comprises: obtaining the service request information sent by a user terminal; changing the single-frequency network according to the service request information. The control entity of the single-frequency network provided by this invention comprises: an obtaining unit, used for obtaining the service request information sent by a user terminal; a controlling unit, used for changing the single-frequency network according to the service request information. This invention realizes the dynamic control of a single-frequency network by changing the single-frequency network according to the service request information sent by a user terminal. Consequently, the service provider can dynamically change a single-frequency network according to the requirement of users and implement the optimization configuration of wireless network resources.

    Abstract: A method and a system for feeding a service state information back are disclosed, which are applied to a multimedia broadcasting/multicasting service system. The method comprises steps as follows: after an event triggered is detected, a user equipment transmits uplink feedback signaling with the service state information of the user equipment to a coordinating entity in a region where the user equipment locates(101); the coordinating entity re-assigns network resources to the user equipments in its region of right according to the uplink feedback signaling(102). The system comprises: user equipments, base station nodes and the coordinating entities. According the solution, when the event is triggered, the user equipment forwardly transmits the uplink feedback signaling so as to assign the network resources, thereby it is unnecessary to periodically use the polling mechanism to statistically count the user equipments, then the system resources engrossed due to the periodical polling are reduced. In addition, the system can simultaneously obtain the service information and application information.

    Abstract: A service state information feedback method and system for a multimedia broadcast/multicast service system are disclosed. The method comprises the steps: the broadcast/multicast service center receives the uplink feedback information containing the service use information transmitted by the user terminal; the broadcast/multicast service center acquires the service use state information according to the uplink feedback information, and sends it to the multimedia broadcast/multicast adjusting entity; the multimedia broadcast/multicast adjusting entity configures the wireless resources according to the service use state information. Compared with making statistic of users and assigning the resources by means of polling in the art, with the solutions, services are adjusted and controlled, and the network resources are flexibly configured, then the solutions can save network resources at the top, decrease the spending of network resources and air interface physical resources, and increase the network use efficiency.

    Abstract: 本发明涉及一种以稻壳灰为原料制备纤维增强SiO 2 气凝胶的方法，其特征在于由以下步骤制得：稻壳灰经无机碱溶液浸取，阳离子交换树脂处理，无机碱中和生成二氧化硅溶胶，待溶胶变得粘稠时与增强纤维复合，静置得到二氧化硅复合凝胶，凝胶经老化、水洗、有机溶剂置换、干燥，制备出纤维增强的SiO 2 气凝胶。获得气凝胶密度为0.1~0.4g/cm 3 ，比表面积可达400~700m2/g，孔体积为1.0~3.0cm 3 /g，平均孔径为5~30nm，抗压强度为0.5~2.5MPa。本发明以价格低廉、来源充足的农业废料稻壳灰代替价格昂贵且有一定毒性的有机硅为原料，以纤维为增强体，制备得到SiO 2 气凝胶，在保持气凝胶优异性能的前提下，既降低了气凝胶的生产成本又提高了气凝胶的力学性能。
