Description

利用后台网络扫描支持多媒体呼叫会话切换的方法和设备 Using background network scanning method and apparatus for supporting a multimedia call session handover

技术领域 FIELD

本发明涉及有线和无线混合网络中的通信。 The present invention relates to a hybrid wired and wireless communication networks. 具体地说本发明的一些实施例涉及利用后台网络扫描切换多媒体呼叫会话的系统和方法。 Some embodiments of the present invention particularly relates to the use of a scanning background network switching system and method for a multimedia call session.

背景技术 Background technique

移动及陆地有线通信服务商面临的一个普遍严重问题是市场竞争。 A common and serious problem of mobile landline communications service providers face market competition. 在如今的竞争性的市场气候下,移动服务商已发现提高其市场份额及保护其业务的一个方法是先发制人及形成联盟,并与陆地有线通信服务商合作。 A method in today's competitive market climate, mobile service providers have been found to increase its market share and protect their business is pre-emptive and form alliances and work with landline communications service providers. 另外,通过配合日益增长的对宽范围媒体形式(诸如MP3编码音频、静止及视频图片、数据、即时消息及电子邮件)的接入需求,服务商正在试图提供具有特色的服务,以赢取最大部分的市场收入。 In addition, with the growing demand for a wide range of media formats (such as MP3 encoded audio, still pictures and video, data, instant messaging and e-mail) access needs, service providers are trying to provide distinctive service to win the greatest income part of the market. 同理,陆地有线通信服务商也发现为提高其市场份额及规避竞争,其必须先发制人及形成联盟,并与移动服务商合作。 Similarly, landline communications service providers also found to increase its market share and avoid competition, it must be pre-emptive and form alliances and work with mobile service providers. 为使市场能够自由地增长,需要对这些趋同的通信形式提供宽范围的经济的接入支持;并且为支持新的手持设备的发展和使用,需要不断提高移动多媒体通信功能的水平。 For markets to be free to grow, the need to provide financial support for a wide range of access convergence of these forms of communication; and to support the development and use of new handheld devices need to continuously improve the level of mobile multimedia communication function.

尽管移动服务商与陆地有线通信服务商之间联盟及合作关系的建立有助于避开竞争,但这种联盟及合作关系也面临着其它的问题。 Despite the establishment of alliances and partnerships between service providers and mobile terrestrial wired communications service providers can help avoid competition, but this alliance and partnership is also facing other problems. 例如,由于可能需要购置不动产,无论是以全部购置或租用的形式,因而移动基础设施(如移动塔)的建立是一种昂贵的风险投资。 For example, due to the possible need to purchase real estate, whether it is the purchase or lease of all forms, and thus build mobile infrastructure (such as mobile towers) is an expensive venture. 移动基础设施还需要建立一个或多个昂贵的骨干链路以处理核心网络业务。 Mobile infrastructure also need to establish one or more expensive core network backbone links to handle business. 另一个与移动相关的问题是移动信号在建筑物(诸如住宅或办公室)内的穿透性及传播性不是很好。 Another problem is related to the movement in the building (such as a home or office) mobile penetration and propagation of the signal is not very good. 这在美国所典型采用的频率上更为明显,其频率在800MHz到1900MHz或1.9GHz之间变化。 This becomes more significant as the typical frequency used in the United States, the frequency varies between 800MHz to 1900MHz, or 1.9GHz.

在使用接入设备时,无线接入设备的用户可以在多个无线网络的覆盖区域内移动。 , Wireless access device the user may move within the coverage area of ​​the plurality of wireless network access device in use. 用户可以知晓多个无线网络的存在,并可以在处于已知无线网络所覆盖的地理区域内利用这一网络。 The user can know the presence of multiple wireless networks, and may be within a known geographical area covered by the wireless network using the network. 实际存在的无线网络的数量要比用户知晓的多一些,因而无线接入设备的用户可能失去利用这些其不知晓的网络进行通信的机会。 The number of users than the actual presence of wireless networks known more, so users wireless access device may lose access to those unaware of its network communications. 可利用的网络中,一些网络可能适合于特定接入设备的用户的通信活动,而其它网络可能不适合。 Available networks, some networks may be adapted to the user's specific access device communication activity, whereas other networks may not be suitable. 另外,无线业务供应商不断增加新的网络容量和特色,并且每天都有新的无线网络供应商进入市场。 In addition, wireless service providers continue to add new features and network capacity, and every day a new wireless network providers to enter the market. 取决于激活的用户数量以及每一个用户的活动,某一天能为用户提供满意质量服务的无线网络,也许另一天或其它时间就不能够满足特定无线接入设备用户的需求。 Depending on the number of active users and each user's activities, one day be able to provide Wi-Fi satisfied with the quality of service for users, maybe another day or another time would not be able to meet the specific needs of users wireless access equipment. 目前,无线接入设备的用户尚无法具有现有的服务供应商选择性的更新信息,且无法知晓从每一个服务供应商处可得到何种服务和/或性能。 Currently, the user of the wireless access device has not been possible to update information on existing service provider selective, and can not know which service and / or performance can be obtained from each service provider.

通过将这样的系统与本发明进行比较,对本领域的普通技术人员来说,传统方案的其它缺点和局限性是显而易见的。 By such a system compared to the present invention, one of ordinary skill in the art, other disadvantages and limitations of the conventional solutions is obvious. 以下将参考附图对本发明进行阐述。 Below with reference to the accompanying drawings of the present invention is illustrated.

每个CDMA及GSM/EDGE/GPRS网络112、114均包括多个小区站点(亦称移动塔),该小区站点位于每一网络的地理小区中。 Each CDMA and GSM / EDGE / GPRS networks 112, 114 each include a plurality of cell sites (also known as mobile column), the cell located at each site in the network of geographical cells. 在GSM/EDGE/GPRS网络114中,每个小区站点,例如小区站点114a可包括基地收发台(BTS),且一个或多个基地收发台可以连接到无线载波中心局114b。 In the GSM / EDGE / GPRS network 114, each cell site, such as cell site 114a may include a base transceiver station (BTS), and one or more base transceiver stations may be connected to the wireless carrier central office 114b. 无线载波中心局114b可包括基站控制器/无线网络控制器(BSC/RNC),如BSC/RNC 114d。 Wireless carrier central office 114b may include a base station controller / radio network controller (BSC / RNC), such as BSC / RNC 114d. 一个或多个基站控制器/无线网络控制器(BSC/RNC)可被连接到GSM/EDGE/GPRS网络114的核心网络114e。 One or more base station controllers / radio network controllers (BSC / RNC) may be connected to a core network 114e GSM / EDGE / GPRS network 114. 该核心网络114e包括称为移动交换中心(MSC)的网络边缘交换机,诸如MSC114g以及服务GPRS支持节点(SGSN)/分组数据服务节点(PDSN)114f。 114e includes the core network is called a mobile switching center (MSC) of the network edge switches, MSC114g and serving GPRS support node (SGSN) / packet data serving node, such as 114f (PDSN). 移动交换中心可经由传输网络110连接到,例如,PSTN 108。 The mobile switching center via the transport network 110 may be connected to, e.g., PSTN 108. 当一个接入设备从第一个小区站点区域移出,进入到第二个小区站点区域,则从第一小区站点接收到的信号功率降低,而从第二小区站点接收到的信号功率增大,从而启动呼叫(通话)从第一小区站点到第二小区站点的越区切换。 When the access device is removed from a first area of ​​a cell site, cell sites into the second area, from a first cell site received signal power to decrease, and the received signal power from a second cell site is increased to, thereby initiating a call (call) from a first cell site to a second cell site handover. 万一,当没有第二个小区站点进行越区切换时,该呼叫(通话)则被第一小区站点功率所维持,直到其衰弱到一个阈值,则其不再能够维持该呼叫(通话)。 In case, when there is no second cell station to perform handoff, the call (call) a first cell site power were maintained until it fades to a threshold value, it is no longer possible to maintain the call (call). 当该功率达到该阈值或跌落到该阈值以下时,则该呼叫(通话)会掉线,且所有相关的呼叫(通话)资源可以被释放。 When the power reaches the threshold or to fall below the threshold, the call (call) will be dropped, and all associated call (call) resources can be released. 期望在住宅或办公室环境有第二网络存在,以使该呼叫(通话)切换到该第二网络。 Desirable to have a second home or office network environment is present, so that the call (call) to switch to the second network.

作为一示例,用户可能在回家的路上,且当该用户接近其住宅时,该信号可能跌落至维持呼叫所需的最小信号功率阈值之下。 As an example, a user may be on the way home, and when the user approaches his house, the signal is likely to fall below a call to maintain the required minimum signal power threshold. 然而,该呼叫可以不掉线,而是被切换至如位于该用户住宅内的PAN或无线局域网(WLAN),或者位于该用户住宅内的免许可无线接入系统。 However, the call may not be dropped, but such is switched to be in the PAN or wireless LAN (WLAN) within the user's home, or in the unlicensed radio access system within the user's home. 例如,参考图1,当接入设备126从GSM/EDGE/GPRS网络114中的正在支持其呼叫的服务小区站点114a附近向在第一区域102内无线接口120移动,该呼叫可以被从GSM/EDGE/GPRS网络114小区站点114a切换到第一区域102中连接到网关118的无线接口120。 For example, referring to FIG. 1, when the access device 126 is supported near its call serving cell site 114a from the GSM / EDGE / GPRS network 114 to the mobile radio interface 120 within the first region 102, the call may be from GSM / EDGE / GPRS network 114 to cell site 102 to switch 114a is connected to the wireless interface 120 of the gateway 118 of the first region. 因此,该呼叫不会掉线,而是被无缝地切换,现在,由网关118通过无线接口120对其进行处理。 Thus, the call is not dropped, but are seamlessly switch, now, from the gateway 118 via wireless interface 120 for processing thereof. 然后,由此而来的无线数据经由到BAP106的宽带连接,传输给GSM/EDGE/GPRS网络114,其中该BAP 106与宽带无线局域网控制器(BWC)114c相连接。 Then, the resulting data via a wireless connection to the broadband BAP106, transmitted to the GSM / EDGE / GPRS network 114, wherein the BAP 106 and a broadband wireless LAN controller (BWC) 114c is connected.
