Description

会话建立方法及装置、储存介质及电子设备 技术领域
本发明涉及通信技术领域，特别涉及一种会话建立方法及装置、储存介质及电子设备。
背景技术
近年来，随着通信技术的快速发展以及移动终端的普及，现有业务所支持的带宽已经无法满足与日俱增的通信需求。在此背景下，多媒体广播多播业务eMBMS的出现为解决这一困境提供了有效的解决方案，eMBMS支持更大带宽，能够提供更多频道以及更加丰富的多媒体内容。
eMBMS通过建立会话的形式向用户提供服务，每一会话的建立，都需要占用一部分会话资源用于传输多媒体内容。3GPP第三代合作伙伴计划协议定义eMBMS最多只能占用60％的会话资源，即一个系统帧的10个子帧中，最多分配6个子帧用于传输多媒体内容，当会话资源需求超过承载能力时，便无法获取足够的会话资源用于传输目标会话提供的多媒体内容，导致目标会话建立失败，用户无法获取所需多媒体内容，降低了eMBMS的服务质量，影响用户的使用体验。
发明内容
有鉴于此，本发明提供了一种会话建立方法，当无法获取足够的会话资源用于建立目标会话时，通过释放话权低于新建会话的已建立会话占用的会话资源，获取建立目标会话所需会话资源，以实现在剩余会话资源无法满足建立目标会话所需会话资源时，建立目标会话，保证eMBMS服务质量的目的。
本发明还提供了一种会话建立装置，用以保证上述方法实际中的实现及应用。

上述的方法，可选的，所述依据预设的会话资源释放策略，对所述第一会话集合占用的会话资源进行释放，包括：
将所述第一会话集合中的各个会话，按其对应的会话优先级，划分为多个优先级会话组；
将每个优先级会话组按优先级由低到高的顺序依次加入第三会话集合，并实时计算所述目标资源与所述第三会话集合占用的会话资源的差值是否不大于当前待加入所述第三会话集合的优先级会话组占用的会话资源；
当不大于时，判断所述当前待加入所述第三会话集合的优先级会话组中，是否包含多个会话；
当包含多个会话时，按每个会话感兴趣用户数由少到多的顺序，逐一将每个会话加入所述第三会话集合，直至所述第三会话集合占用的会话资源不小于所述目标资源时，停止加入；
释放当前第三会话集合占用的会话资源。
上述的方法，可选的，还包括：
确定当前剩余会话资源满足所述目标会话的建立需求时，直接建立目标会话。
上述的方法，可选的，还包括：
