支持移动终端在具有不同协议版本的基站间移动的方法Method for supporting mobile terminal to move between base stations with different protocol versions

技术领域technical field

本发明涉及通信领域,更具体地涉及一种支持移动终端在具有不同协议版本的基站间移动的方法。The present invention relates to the communication field, and more specifically relates to a method for supporting a mobile terminal to move between base stations with different protocol versions.

背景技术Background technique

CDMA20001xEV-DO(IS-856)是CDMA标准家族的一个分支,它包含一系列不断演进的协议。较新的IS-856协议版本不仅包含先前版本的特性和功能,还会加以改善并增加新的特性。为了支持新的特性,无论基站系统还是移动终端通常都需要从硬件和软件两方面进行升级。CDMA20001xEV-DO (IS-856) is a branch of the CDMA standard family, which includes a series of evolving protocols. Newer IS-856 protocol versions not only contain the features and functions of previous versions, but also improve and add new features. In order to support new features, both the base station system and the mobile terminal usually need to be upgraded in terms of hardware and software.

IS-856版本0和版本A是该协议族先后出现的两个标准,版本A相对于版本0有较大改进,物理层和MAC层协议的增强可以支持更高的前反向数据传输速率、更有效地降低用户间干扰;应用层协议的增强为支持用户业务的QoS特性提供了有力保障;会话层协议的增强可以支持更灵活的无线参数配置,典型地,版本A支持终端和基站系统初始就协商多套具有不同无线特性的参数配置。IS-856 version 0 and version A are two standards that appeared successively in this protocol family. Compared with version 0, version A has great improvement. The enhancement of physical layer and MAC layer protocol can support higher forward and reverse data transmission rate, More effectively reduce the interference between users; the enhancement of the application layer protocol provides a strong guarantee for supporting the QoS characteristics of user services; the enhancement of the session layer protocol can support more flexible wireless parameter configuration, typically, version A supports the terminal and base station system initial Negotiate multiple sets of parameter configurations with different wireless characteristics.

基于IS-856版本0的基站系统和移动终端已经得到较为广泛的商用,而版本A的诸多增强特性也引起越来越多运营商的关注,将版本0的系统升级到版本A的需求变得日益迫切起来。对于基站系统而言,基站控制器通常只需要软件升级,但基站收发信机由于包含了核心的调制解调单元,所以对于物理层有较大变化的演进协议版本,必须同时升级硬件和软件才能完全支持。但是运营商出于保护投资的考虑,会允许一些在硬件上只能支持较低协议版本的基站收发信机在全网升级后继续存在。对于这种混合配置的组网方式,存在如下问题:当具有协议版本0的移动终端在具有不同协议版本的基站间移动时,需要决定采用何种特性的无线参数配置才能被兼容,而当具有协议版本A的移动终端从协议版本较高的基站移动到协议版本较低的基站时,可能会因为信令格式或数据传输格式不被基站支持而导致掉话,当它从协议版本较低的基站移动到协议版本较高的基站时,又可能因为无线参数配置的限制而无法应用各种增强特性。Base station systems and mobile terminals based on IS-856 version 0 have been widely used in commercial use, and many enhanced features of version A have attracted more and more attention from operators. The need to upgrade version 0 systems to version A has become increasingly urgent. For the base station system, the base station controller usually only needs software upgrades, but since the base station transceiver contains the core modem unit, it is necessary to upgrade the hardware and software at the same time for the evolved protocol version that has a large change in the physical layer. fully support. However, in consideration of investment protection, operators will allow some base transceiver stations whose hardware can only support lower protocol versions to continue to exist after the entire network is upgraded. For this mixed configuration networking mode, there is the following problem: when a mobile terminal with protocol version 0 moves between base stations with different protocol versions, it needs to decide which wireless parameter configuration to use to be compatible. When a mobile terminal of protocol version A moves from a base station with a higher protocol version to a base station with a lower protocol version, it may cause call drop because the signaling format or data transmission format is not supported by the base station. When the base station moves to a base station with a higher protocol version, it may not be able to apply various enhanced features due to the limitation of wireless parameter configuration.

面对上述问题,以下需求是显而易见的:一方面,升级后的网络,不但可以接纳具有较高协议版本的终端,而且能够继续为协议版本较低的终端服务;另一方面,对于协议版本较高的移动终端,当它在混合配置的网络内移动时,网络应能根据当前与该终端通信的基站收发信机的能力自动地指导终端采用与不同协议版本相匹配的无线参数来尽可能获取更高质量的服务,同时又要避免服务变得不可用进而导致掉话。Faced with the above problems, the following requirements are obvious: on the one hand, the upgraded network can not only accept terminals with higher protocol versions, but also continue to serve terminals with lower protocol versions; High mobile terminal, when it moves in the mixed configuration network, the network should be able to automatically guide the terminal to adopt wireless parameters that match different protocol versions to obtain as much Higher quality of service while avoiding service becoming unavailable and resulting in dropped calls.

The method according to the invention can be applied to a CDMA communication system.

图2是具有协议版本0的终端在网络下起呼以及移动的实施例图。如图2所示,具有协议版本0的终端可能在支持协议版本0的基站下起呼(A处),也可能在支持协议版本A的基站下起呼(B处),其后可能移动到有多个基站同时覆盖的区域(C处)。如果终端初始接入网络,基站控制器会与终端协商一套具有版本0特性的会话配置信息并在协商完成后启用这套配置信息。此后终端起呼及移动切换过程中,基站控制器对其的控制参见图4和图5所示的流程图。Fig. 2 is an embodiment diagram of a terminal with protocol version 0 making a call and moving under the network. As shown in Figure 2, a terminal with protocol version 0 may initiate a call at a base station supporting protocol version 0 (at A), or may initiate a call at a base station supporting protocol version A (at B), and then may move to An area with multiple base stations covering simultaneously (at C). If the terminal initially accesses the network, the base station controller will negotiate with the terminal a set of session configuration information with version 0 features and enable this set of configuration information after the negotiation is completed. Thereafter, during the terminal calling and mobile switching process, the control of the base station controller refers to the flow charts shown in FIG. 4 and FIG. 5 .

图3是具有协议版本A的终端在网络下起呼以及移动的实施例图。如图3所示,具有协议版本A的终端可能在支持协议版本0的基站下起呼(A处),也可能在支持协议版本A的基站下起呼(B处),其后可能移动到有多个基站同时覆盖的区域(C处)。如果终端初始接入网络,基站控制器会与终端协商至少两套会话配置信息,至少有一套全部采用版本0能够支持的协议子类型以及协议协商参数,至少有一套全部采用版本A能够支持的协议子类型以及协议协商参数。如果终端是在A处起呼,出于最适配的考虑,协商结束后基站控制器会要求启用具有版本0特性的会话配置信息,同理,如果是在B处起呼,则基站控制器会要求启用具有版本A特性的会话配置信息,如果是在C处起呼,则基站控制器会要求启用与终端上报的参考导频所在基站的协议版本相一致的会话配置信息。此后终端起呼及移动切换过程中,基站控制器对其的控制参见图4和图4所示的流程图。Fig. 3 is an embodiment diagram of a terminal with protocol version A making a call and moving under the network. As shown in Figure 3, a terminal with protocol version A may initiate a call at a base station supporting protocol version 0 (at A), or may initiate a call at a base station supporting protocol version A (at B), and then may move to An area with multiple base stations covering simultaneously (at C). If the terminal initially accesses the network, the base station controller will negotiate at least two sets of session configuration information with the terminal, at least one set adopts all the protocol subtypes and protocol negotiation parameters that version 0 can support, and at least one set adopts all the protocols that version A can support Subtype and protocol negotiation parameters. If the terminal initiates a call at A, for the sake of best fit, the base station controller will request to enable session configuration information with version 0 features after the negotiation is completed. Similarly, if the terminal initiates a call at B, the base station controller The session configuration information with the characteristics of version A will be required to be enabled. If the call is initiated at C, the base station controller will require the activation of the session configuration information consistent with the protocol version of the base station where the reference pilot reported by the terminal is located. Thereafter, during the terminal calling and mobile switching process, the control of the base station controller refers to the flow chart shown in FIG. 4 and FIG. 4 .

图4是移动终端起呼时的控制流程图。如图4所示,移动终端起呼过程包含如下步骤:Fig. 4 is a control flow chart when the mobile terminal initiates a call. As shown in Figure 4, the calling process of the mobile terminal includes the following steps:

S402,终端上报连接建立请求及路由更新消息;S402, the terminal reports a connection establishment request and a routing update message;

S404,基站控制器根据本地存储的终端的会话配置信息判断终端协议版本类型,无论协商一套或多套会话配置信息,如果其中物理层协议子类型均为缺省值,则判断该终端为支持协议版本0的终端,如果至少有一套会话配置信息中物理层子类型为子类型2,则判断该终端为支持协议版本A的终端;S404. The base station controller judges the terminal protocol version type according to the session configuration information of the terminal stored locally. No matter one or more sets of session configuration information are negotiated, if the subtype of the physical layer protocol is the default value, it is judged that the terminal supports For a terminal of protocol version 0, if the physical layer subtype in at least one set of session configuration information is subtype 2, it is determined that the terminal is a terminal supporting protocol version A;

S406,如果终端的协议版本类型为版本0,则维持当前的会话配置信息不变,同时为终端上报的所有符合加入有效集条件的导频分配资源并继续后续的连接建立流程。因为终端上报的导频中无论属于支持协议版本0的基站还是属于支持协议版本A的基站,都能完全支持该终端当前会话配置的所有特性,所以对导频不做区别;S406. If the protocol version type of the terminal is version 0, keep the current session configuration information unchanged, and at the same time allocate resources for all pilots reported by the terminal that meet the conditions for joining the active set, and continue the subsequent connection establishment process. Because the pilot reported by the terminal belongs to the base station that supports protocol version 0 or the base station that supports protocol version A, it can fully support all the features of the current session configuration of the terminal, so no distinction is made between the pilots;

S408,如果终端的协议版本类型为版本A,因为该种终端可能协商多套会话配置信息,所以需要首先判断当前启用的会话配置信息的版本特性是否与之一致;S408, if the protocol version type of the terminal is version A, because this type of terminal may negotiate multiple sets of session configuration information, it is necessary to first determine whether the version characteristics of the currently enabled session configuration information are consistent with it;

S410,如果当前启用的会话配置信息的版本特性是版本0的,需要查询起呼小区所在的基站收发信机的协议版本类型;S410, if the version characteristic of the currently enabled session configuration information is version 0, it is necessary to query the protocol version type of the base station transceiver where the calling cell is located;

S412,如果起呼小区所在的基站收发信机的协议版本类型也是版本0的,则维持当前会话配置信息,并为终端上报的所有符合加入有效集条件的导频分配资源并继续后续的连接建立流程;S412, if the protocol version type of the base transceiver station where the calling cell is located is also version 0, maintain the current session configuration information, allocate resources for all pilots reported by the terminal that meet the conditions for joining the active set, and continue subsequent connection establishment process;

S414,如果起呼小区所在的基站收发信机的协议版本类型是版本A的,与当前会话配置信息的版本特性不一致,为了让终端能获取更高质量的服务,基站控制器会在公共信道发起会话配置信息的切换,要求终端切换到具有版本A特性的会话配置信息再重新起呼;S414, if the protocol version type of the base transceiver station where the originating cell is located is version A, which is inconsistent with the version characteristics of the current session configuration information, in order to allow the terminal to obtain higher quality services, the base station controller will initiate on the public channel The switching of session configuration information requires the terminal to switch to the session configuration information with version A features and then start calling again;

S416,如果在步骤S408判断当前启用的会话配置信息的版本特性是版本A的,同样要查询起呼小区所在的基站收发信机的协议版本类型;S416, if it is judged in step S408 that the version characteristic of the currently enabled session configuration information is version A, the protocol version type of the base transceiver station where the calling cell is located will also be inquired;

S418,如果起呼小区所在的基站收发信机的协议版本类型是版本0的,为了保证连接可以正常建立,基站控制器会在公共信道发起会话配置信息的切换,要求终端切换到具有版本0特性的会话配置信息后再重新起呼,这样在连接建立过程中所使用的无线参数才能为基站所识别;S418, if the protocol version type of the base transceiver station where the calling cell is located is version 0, in order to ensure that the connection can be established normally, the base station controller will initiate the switching of session configuration information on the public channel, requiring the terminal to switch to version 0 features Then start the call again, so that the wireless parameters used in the connection establishment process can be identified by the base station;

S420,如果起呼小区所在的基站收发信机的协议版本类型是版本A的,需要剔除属于协议版本0基站的小区,因为这些小区无法支持某些版本A特性的信令或数据传输格式;S420, if the protocol version type of the base station transceiver where the originating cell is located is version A, it is necessary to exclude cells belonging to the protocol version 0 base station, because these cells cannot support some signaling or data transmission formats with version A characteristics;

S422,在执行了步骤S420的剔除操作后,为剩余导频分配资源并继续连接建立流程。S422. After performing the elimination operation in step S420, allocate resources for the remaining pilots and continue the connection establishment process.

在步骤S420有一种场景需要特别提到,就是所有属于协议版本A基站的小区的导频强度都没有超过切换加门限,而且所有属于协议版本0基站的小区中最强的导频强度与所有属于协议版本A基站的小区中最强的导频强度相比,强度要超过一个比较门限,则为了避免勉强在属于协议版本A基站的小区上建立连接而后很快掉话,基站控制器会采用与步骤S418相同的方法控制终端切换到具有版本0特性的会话配置信息后再重新起呼。步骤S420的特殊场景提到的导频强度比较门限的调整范围是3-5dB。In step S420, there is a scenario that needs to be specially mentioned, that is, the pilot strengths of all cells belonging to protocol version A base stations do not exceed the handover threshold, and the strongest pilot strength among all cells belonging to protocol version 0 base stations is the same as that of all cells belonging to protocol version 0 base stations. Compared with the strongest pilot strength in the cell of the protocol version A base station, if the strength exceeds a comparison threshold, in order to avoid barely establishing a connection on the cell belonging to the protocol version A base station and then quickly dropping the call, the base station controller will adopt the same method as The same method as step S418 controls the terminal to switch to the session configuration information with version 0 characteristics and then restarts the call. The adjustment range of the pilot strength comparison threshold mentioned in the special scenario of step S420 is 3-5 dB.

图5是移动终端在切换过程中的控制流程图。如图5所示,移动终端在切换过程中的控制流程包含如下步骤:Fig. 5 is a control flow diagram of the mobile terminal during the handover process. As shown in Figure 5, the control flow of the mobile terminal in the handover process includes the following steps:

S502,连接维持过程中,终端在业务信道发送路由更新消息,请求切换加入新的导频;S502, during the connection maintenance process, the terminal sends a routing update message on the traffic channel, requesting to switch and add a new pilot;

S504,基站控制器根据本地存储的终端的会话配置信息判断终端协议版本类型,无论协商一套或多套会话配置信息,如果其中物理层协议子类型均为缺省值,则判断该终端为支持协议版本0的终端,如果至少有一套会话配置信息中物理层子类型为子类型2,则判断该终端为支持协议版本A的终端;S504. The base station controller judges the terminal protocol version type according to the session configuration information of the terminal stored locally. No matter one or more sets of session configuration information are negotiated, if the subtype of the physical layer protocol is the default value, it is judged that the terminal supports For a terminal of protocol version 0, if the physical layer subtype in at least one set of session configuration information is subtype 2, it is determined that the terminal is a terminal supporting protocol version A;

S506,如果终端的协议版本类型为版本0,则维持当前的会话配置信息不变,同时为终端上报的所有符合加入有效集条件的导频分配资源并继续后续的切换流程;S506. If the protocol version type of the terminal is version 0, maintain the current session configuration information unchanged, and at the same time allocate resources for all pilots reported by the terminal that meet the conditions for joining the active set, and continue the subsequent switching process;

S508,如果终端的协议版本类型为版本A,接下来需要判断当前启用的会话配置信息的版本特性是否与之一致;S508, if the protocol version type of the terminal is version A, then it is necessary to determine whether the version characteristics of the currently enabled session configuration information are consistent with it;

S510,如果当前启用的会话配置信息的版本特性是版本0的,需要根据路由更新消息中属于不同协议版本基站的导频的强度对比来判断是否需要发起会话配置信息的更新流程。如果路由更新消息中所有属于协议版本0基站的小区的导频强度都没有超过切换加门限,而且所有属于协议版本A基站的小区中最强的导频强度与所有属于协议版本0基站的小区中最强的导频强度相比,强度要超过一个比较门限,则为了避免有效集中全都是属于协议版本A基站的小区却只能进行版本0特性的服务这种资源浪费情况的存在,认为满足会话配置信息更新条件;S510, if the version characteristic of the currently enabled session configuration information is version 0, it is necessary to determine whether to initiate an update process of the session configuration information according to the strength comparison of pilots belonging to different protocol version base stations in the routing update message. If the pilot strength of all the cells belonging to the protocol version 0 base station in the routing update message does not exceed the handover plus threshold, and the strongest pilot strength among all the cells belonging to the protocol version A base station is the same as that of all the cells belonging to the protocol version 0 base station Compared with the strongest pilot strength, if the strength exceeds a comparison threshold, in order to avoid the waste of resources that all belong to the protocol version A base station in the effective concentration, but can only provide the service of version 0 characteristics, it is considered that the session is satisfied Configuration information update conditions;

S512,如果会话配置信息更新条件不满足,基站控制器维持当前会话配置信息,为终端上报的所有符合加入有效集条件的导频分配资源并继续后续的切换流程;S512, if the session configuration information update condition is not met, the base station controller maintains the current session configuration information, allocates resources for all pilots reported by the terminal that meet the conditions for joining the active set, and continues the subsequent handover process;

S514,如果会话配置信息更新条件满足,基站控制器会在业务信道发起会话配置信息更新流程,控制终端切换到具有版本A特性的会话配置信息后再重新起呼,尽管会造成一次掉话,但其后终端可以获取更高质量的服务,利大于弊;S514, if the session configuration information update condition is satisfied, the base station controller will initiate a session configuration information update process on the traffic channel, control the terminal to switch to the session configuration information with the version A feature and then start the call again, although it will cause a call drop, but Afterwards, the terminal can obtain higher quality services, and the advantages outweigh the disadvantages;

S516,如果当前启用的会话配置信息的版本特性是版本A的,也需要根据路由更新消息中属于不同协议版本基站的导频的强度的对比来判断是否需要发起会话配置信息的更新流程。如果路由更新消息中所有属于协议版本A基站的小区的导频强度都没有超过切换加门限,而且所有属于协议版本0基站的小区中最强的导频强度与所有属于协议版本A基站的小区中最强的导频强度相比,强度要超过一个比较门限,则为了避免勉强在属于协议版本A基站的小区上维持连接却由于无线条件太差造成原有服务质量不能保证,也为了避免无谓的资源浪费,认为满足会话配置信息更新条件;S516, if the version characteristic of the currently enabled session configuration information is version A, it is also necessary to judge whether it is necessary to initiate an update process of the session configuration information according to the comparison of the strengths of pilots belonging to base stations of different protocol versions in the routing update message. If the pilot strength of all the cells belonging to the protocol version A base station in the routing update message does not exceed the handover plus threshold, and the strongest pilot strength among all the cells belonging to the protocol version 0 base station is the same as that of all the cells belonging to the protocol version A base station Compared with the strongest pilot strength, the strength must exceed a comparison threshold, in order to avoid barely maintaining the connection on the cell belonging to the protocol version A base station but the original service quality cannot be guaranteed due to poor wireless conditions, and to avoid unnecessary Waste of resources, it is considered that the update condition of session configuration information is met;

S518,如果会话配置信息更新条件不满足,基站控制器维持当前会话配置信息,并从路由更新消息中剔除属于协议版本0基站的小区,因为这些小区无法支持某些版本A特性的信令或数据传输格式;S518, if the session configuration information update condition is not satisfied, the base station controller maintains the current session configuration information, and removes the cells belonging to the protocol version 0 base station from the routing update message, because these cells cannot support the signaling or data of some version A features transmission format;

S520,在剔除操作结束后,基站控制器为剩余符合加入有效集条件的导频分配资源并加入当前有效集;S520, after the elimination operation ends, the base station controller allocates resources for the remaining pilots that meet the conditions for joining the active set and adds them to the current active set;

S522,如果会话配置信息更新条件满足,基站控制器会在业务信道发起会话配置信息更新流程,控制终端切换到具有版本0特性的会话配置信息后再重新起呼,尽管会造成一次掉话,但可以缩短占用过多资源却不能使用期望的高等级服务的时间,同样利大于弊。S522, if the session configuration information update condition is satisfied, the base station controller will initiate a session configuration information update process on the traffic channel, control the terminal to switch to the session configuration information with version 0 characteristics and then start the call again, although it will cause a call drop, but It can also shorten the time when excessive resources are used but the desired high-level service cannot be used, and the advantages outweigh the disadvantages.

步骤S510和步骤S516使用的导频强度比较门限的调整范围是3-5dB。The adjustment range of the pilot strength comparison threshold used in step S510 and step S516 is 3-5 dB.
