为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作一简单地介绍, 显而易见地, 下 面描述中的附图是本发明的一些实施例, 对于本领域普通技术人员来讲, 在 不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的附图。

图 11为本发明实施例提供的 MME结构示意图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明 中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获得的所 有其他实施例, 都属于本发明保护的范围。
当用户设备发起数据业务时, 网络出现拥塞可能导致数据业务的速率降 低或数据业务中断; 相对于数据业务, 语音业务对网络质量的要求更高, 当 用户设备发起语音业务时, 网络出现拥塞可能导致语音业务的通话质量降低 或语音呼叫失败。 语音业务呼叫失败或者质量降低 (例如通话时出现杂音或 者通话断断续续等) 会极大影响用户体验。 因此在网络拥塞时, 需要优先保 障语音业务。
图 1为无线通信网络的架构示意图, 如图 1所示的无线通信网络 100。 该无线通信网络 100包括若干基站 110和其他网络实体, 用以支撑若干用户 设备 120进行通信。 为方便描述, 以下以 LTE网络为例进行说明。
基站 110, 可以是 LTE中的演进型基站 ( evolved NodeB, eNB) 。 一个 基站 110可能支持 /管理一个或多个小区, 用户设备 (User Equipment, UE) 120需要和网络通信时, 它将选择一个小区发起接入。
UE120也可称之为移动终端 (Mobile Terminal, MT) 、 移动台 (Mobile Station, MS)等, 可以经无线接入网 (Radio Access Network, RAN) 与一个 或多个核心网进行通信。
核心网设备 130与一个或多个基站 110连接, 核心网设备 130包括移动
管理实体 (Mobility Management Entity, MME) 。
由于硬件能力限制或软件配置的限制, 基站 110能够接入的 UE120数量 有限。 原则上, 当基站 110已接入的 UE120的数量到达基站 110所支持的最 大数量时, 当新的 UE120向基站 110想要接入网络时, 基站 110将拒绝该 UE120接入网络。
UE120接入网络时需要向基站 110发送无线资源控制 (Radio Resource Control, RRC) 连接请求, RRC连接请求用于请求网络中的无线资源, 当基 站 110允许该 UE120接入时, 才会为该 UE120分配无线资源。但当基站 110 处于拥塞状态时, UE120向基站 110发送 RRC连接请求, 基站 110已经没有 额外的无线资源可进行分配, UE120将无法进行业务连接, 对于语音业务来 说, 这是不能接受的。
现有技术中, 当 UE向基站发送 RRC连接请求时, 该 RRC连接请求中 携带建立原因, 该建立原因包括: 紧急 (Emergency) 、 高优先级访问 (High Priority Access ) 、 禾多动被口 ^!访问 (Mobile Terminating Access, mt- Access ) 、 移云力主叫访问(Mobile Originating Access, mo-Access)、移云力主叫信令(Mobile Originating Signaling, mo- Signaling)、禾多动主叫数据 ( Mobile Originating Data, mo-Data) 、 或延迟容忍访问 (Delay Tolerant Access)等。 但上述建立原因不 区分是否是语音业务, 基站无法通过上述原因值判断发送 RRC连接请求的 UE是否需要进行语音业务。
基站处于拥塞状态可以包括: 已接入的 UE数量已经达到该基站所支持 的最大接入用户数量; 或者, 已接入的 UE数量已经达到该基站购买的接入 许可 (License) 数量。
为了解决上述问题, 本发明实施例提供了一种语音业务的 UE接入网络 的方法和装置, 通过在 UE向基站发送的 RRC连接请求中添加语音呼叫的建 立原因, 使基站在拥塞状态时也允许进行语音业务的 UE接入网络, 进而提 高语音业务的用户体验。 图 2为本发明实施例提供的语音业务的 UE接入网络的方法流程图, 如 图 2所示, 本实施例的方法包括:
S201 , 第一 UE向基站发送 RRC连接请求, 该 RRC连接请求中的建立
原因为语音呼叫。
为了指示语音呼叫的业务, RRC连接请求中的建立原因包括语音呼叫的 建立原因, 语音呼叫包括但不限于 VOIP或 CSFB。
当处于空闲态的第一 UE发起语音业务时, 向基站发送 RRC连接请求, 该 RRC连接请求中的建立原因为语音呼叫。
5202, 当基站处于拥塞状态时, 基站向第一 UE发送 RRC连接建立。 当基站处于拥塞状态时, 由于向基站发送 RRC连接请求的第一 UE的建 立原因为语音呼叫, 为了保证语音呼叫的 UE能够接入网络, 当基站接收到 第一 UE发送的 RRC连接请求后, 基于该语音呼叫的建立原因, 基站会向第 一 UE发送 RRC连接建立。
5203 , 第一 UE向基站发送 RRC连接建立完成, 该 RRC连接建立完成 中携带业务请求。
当第一 UE接收到 RRC连接建立后, 向基站发送 RRC连接建立完成, 其中携带业务请求, 业务请求为非接入层(Non- Access Stratum, NAS)消息。
S204, 基站将业务请求发送给 MME。
基站收到 UE发送的 RRC连接建立完成后, 获取到业务请求。 由于业务 请求为 NAS消息, 基站将该业务请求发送给 MME, 可选的, 基站将该业务 请求携带在初始 UE消息中发送给 MME。
5205, MME向基站发送初始上下文建立请求。
MME接收到业务请求后, 为第一 UE分配相关地接入信息, 并为该第一
UE配置初始上下文信息, 然后向基站发送初始上下文建立请求。
5206, 基站向第一 UE发送 RRC连接重配置。
基站收到 MME发送的初始上下文建立请求后, 向第一 UE发送 RRC连 接重配置。
S207, 第一 UE向基站发送 RRC连接重配置完成。
第一 UE接收基站发送的 RRC连接重配置, 执行配置, 当配置完成后, 向基站发送 RRC连接重配置完成, 以使基站收到第一 UE发送的 RRC连接 重配置完成后和 MME进一歩信息交互, 从而第一 UE完成语音业务接入。
通常来说, 基站可以在一定范围内超负荷运转。 本实施例, 通过在 UE 向基站发送的 RRC连接请求中添加语音呼叫的建立原因,使基站在拥塞状态
时也允许进行语音业务的 UE接入网络, 进而提高语音业务 UE的用户体验。 图图 33为为本本发发明明实实施施例例提提供供的的语语音音业业务务的的 UUEE接接入入网网络络的的方方法法流流程程图图,, 如如 图图 33所所示示,, 本本实实施施例例的的方方法法包包括括::

其中 S309中基站释放第二 UE的资源的操作可以在 S302之后的任意时 间进行, 也就是说 S309的执行顺序不以本实施例为限。 基站可以确定第二 UE后立刻释放该第二 UE的资源, 以使基站在正常运转状态下让第一 UE接 入网络, 也可以在基站超负荷运转状态下, 先让第一 UE接入网络, 然后再 释放确定的第二 UE的资源, 最终确保基站运转在正常状态。
优选的, 基站在收到第一 UE发送的 RRC连接重配置完成后, 释放第二 尽管基站可以在一定范围内超负荷运转, 但既保证基站在正常范围内运 转又让语音业务的 UE接入网络更有助于确保语音业务的 UE的用户体验。根 据建立原因, 基站确定非语音业务的第二 UE、 释放第二 UE的资源, 使语音 业务的 UE在基站拥塞的时候能够接入网络,进一歩确保语音业务的第一 UE 的用户体验。
本发明实施例, 通过在 UE向基站发送的 RRC连接请求中添加语音呼叫 的建立原因, 使基站在拥塞状态时也允许进行语音业务的 UE接入网络, 既 保证基站在正常范围内运转又让语音业务的 UE接入网络, 进而提高语音业 务 UE的用户体验。 图 4为本发明实施例提供的语音业务的 UE接入网络的方法流程图。 如 图 4所示, 本实施例的方法包括:
S401 , 第一 UE向基站发送 RRC连接请求, 该 RRC连接请求中的建立 原因为语音呼叫。
5402, 当基站处于拥塞状态时, 基站向第一 UE发送 RRC连接建立。
5403 , 第一 UE向基站发送 RRC连接建立完成, 该 RRC连接建立完成 中携带业务请求。
S404, 基站将业务请求发送给 MME。
5405, MME向基站发送初始上下文建立请求。
5406, 基站确定一个可释放资源的第二 UE。
基站接收到 MME发送的初始上下文建立请求后, 确定一个可释放资源 的第二 UE。 基站可以利用获取的信息, 从不同维度确定可释放资源的第二
可选的, 基站可以根据用户优先级或业务优先级或建立原因, 从已接入 的 UE中确定可释放资源的第二 UE。
初始上下文建立请求中包含第一 UE的用户优先级或业务优先级。 基站 可以获知已接入 UE的用户优先级或业务优先级。 根据用户优先级或业务优 先级, 基站确定一个可以释放资源的第二 UE。 具体的, 基站选择用户优先级 或业务优先级较低的已接入 UE作为第二 UE。
可选的, 基站还可以根据已接入 UE的用户优先级和建立原因, 或业务 优先级和建立原因, 从已接入的 UE中确定可释放资源的第二 UE。 由于基站 已接入的 UE中,可能有若干 UE的用户优先级或业务优先级是相同的, 因此 若仅根据 UE的用户优先级或业务优先级确定可释放资源的第二 UE, 则可能 确定的第二 UE是正在进行语音业务的 UE。因此同时根据用户优先级和建立 原因, 或业务优先级和建立原因, 则当已接入的 UE中用户优先级或业务优 先级最低的 UE为两个以上时,可以尽量选择非语音的呼叫的已接入 UE作为 第二 UE。
可选的, 用户优先级或业务优先级为分配和保留优先级 (Allocation and
Retention Priority, ARP) 。
可选的, 基站可从已接入的 UE中选择一个建立原因为非语音呼叫的第 二 UE。

5407 , 基站向第一 UE发送 RRC连接重配置。
基站确定可释放资源的第二 UE后, 向第一 UE发送 RRC连接重配置。
5408, 第一 UE向基站发送 RRC连接重配置完成。
5409, 基站释放第二 UE的资源。
可选的, 基站可以在确定一个可释放资源的第二 UE后的任何阶段释放 该第二 UE的资源。
S407-S409的具体实施方法与图 3的 S307〜S309的实施方法一致,不再 赘述。
根据用户优先级或业务优先级, 或在此基础上进一歩考虑建立原因, 基 站确定第二 UE、 释放第二 UE的资源, 进一歩确保语音业务第一 UE的用户
体验。
本发明实施例, 通过在 UE向基站发送的 RRC连接请求中添加语音呼叫 的建立原因, 使基站在拥塞状态时也允许进行语音业务的 UE接入网络, 既 保证基站在正常范围内运转又让语音业务的 UE接入网络, 进而提高语音业 务 UE的用户体验。
进一歩地, 图 2至图 4所示实施例中, 通过判断, 基站可确定是否处于 拥塞状态: 当已接入的 UE 的数量达到基站的最大能力值时, 基站判断该基 站处于拥塞状态; 或者, 当已接入的 UE 的数量达到基站的接入许可数量值 时, 基站判断该基站处于拥塞状态。
图 2至图 4所示实施例中, 通过增加语音呼叫的建立原因, 进行语音呼 叫的 UE在向基站发送的 RRC连接请求中携带语音呼叫的建立原因, 使基站 在拥塞状态时, 根据该语音呼叫的建立原因向该 UE发送 RRC连接建立, 以 使 UE进一歩完成语音业务接入。 可选的, 如图 5所示, 本发明实施例提供了另一种可能的实现方法。 图
5为本发明实施例提供的语音业务的 UE接入网络的方法流程图。本实施例的 方法包括:
5501 , 第一 UE向基站发送 RRC连接请求。
当处于空闲态的第一 UE发起语音业务时, 向基站发送 RRC连接请求, 该 UE可以是主叫 UE, 也可以是被叫 UE。
5502, 当基站处于拥塞状态时, 基站向第一 UE发送 RRC连接建立。 当基站处于拥塞状态时, 不论第一 UE发起的是什么业务, 基站都会向 第一 UE发送 RRC连接建立。
5503 , 第一 UE向基站发送 RRC连接建立完成, 该 RRC连接建立完成 中携带业务请求, 该业务请求中携带语音呼叫的指示信息。
当第一 UE接收到 RRC连接建立后, 向基站发送 RRC连接建立完成, 其中携带业务请求, 业务请求为 NAS消息, 其中该业务请求中包括语音呼叫 的指示信息。
5504, 基站将业务请求发送给 MME。
基站收到 UE发送的 RRC连接建立完成后, 获取到业务请求。 由于业务
请求为 NAS消息, 基站将该业务请求发送给 MME, 可选的, 基站将该业务 请求携带在初始 UE消息中发送给 ΜΜΕ。
5505, ΜΜΕ向基站发送初始上下文建立请求。
ΜΜΕ接收到业务请求后, 为第一 UE分配相关地接入信息, 并为该第一 UE配置初始上下文信息, 然后向基站发送初始上下文建立请求。
5506, 基站向第一 UE发送 RRC连接重配置。
基站收到 ΜΜΕ发送的初始上下文建立请求后, 向第一 UE发送 RRC连 接重配置。
S507, 第一 UE向基站发送 RRC连接重配置完成。
与前述实施例通过在 RRC连接请求中扩展语音呼叫的建立原因不同,本 发明实施例通过在业务请求中携带语音呼叫的指示信息, 以使语音呼叫的用 户设备在基站拥塞时也能正常接入网络。 图 6为本发明实施例提供的语音业务的 UE接入网络的方法流程图, 如 图 6所示, 本实施例的方法包括:
5601 , 第一 UE向基站发送 RRC连接请求。
在本发明实施例中,沿用现有技术中的 RRC连接请求不增加语音呼叫的 建立原因。
5602, 当基站处于拥塞状态时, 基站向第一 UE发送 RRC连接建立。 基站接收到第一 UE发送的 RRC连接请求后, 无论该第一 UE是何种业 务, 在基站处于拥塞状态时, 基站向第一 UE发送 RRC连接建立, 以使该第 一 UE继续进行后续接入流程。
5603 , 第一 UE向基站发送 RRC连接建立完成, 该 RRC连接建立完成 中携带业务请求, 该业务请求中携带语音呼叫的指示信息。
第一 UE在接收到基站发送的 RRC连接建立后, 向基站发送 RRC连接 建立完成, 其中携带业务请求, 并在该业务请求中携带语音呼叫的指示信息。
5604, 基站将业务请求发送给 ΜΜΕ。
基站接收到 RRC连接建立后, 将其中携带的业务请求发送给 ΜΜΕ。
5605, ΜΜΕ为第一 UE配置初始上下文建立请求, 该初始上下文建立请 求中的用户优先级或业务优先级为高优先级。
由于业务请求中携带语音呼叫的指示信息, 因此 MME在接收到业务请 求后, 得知该第一 UE为语音呼叫的 UE。
UE在接入网络的过程中, MME都会在初始上下文建立请求中为 UE配 置不同的用户优先级或业务优先级, UE的用户优先级或业务优先级低意味着 UE是非重要 UE或 UE正在进行的是非重要业务。 在 MME接收到的业务请 求中包括语音呼叫的指示信息时, 将第一 UE的用户优先级或业务优先级配 置高优先级。
上述用户优先级或业务优先级包括分配和保留优先级 (Allocation and Retention Priority, ARP) 。
S606, MME向基站发送初始上下文建立请求。
5607, 基站确定一个可释放资源的第二 UE。
基站可获知每个已接入的 UE的用户优先级或业务优先级, 因此当基站 接收到 MME发送的初始上下文配置后, 基站获取到第一 UE的用户优先级 或业务优先级。基站根据第一 UE的用户优先级或业务优先级以及已接入 UE 的用户优先级或业务优先级, 确定一个已接入的 UE为可以释放资源的第二 可选的, 基站确定用户优先级或业务优先级最低的已接入 UE作为第二 UE; 可选的, 基站可随机确定一个已接入的 UE作为第二 UE。
5608, 基站向第一 UE发送 RRC连接重配置。
基站确定可释放资源的第二 UE后, 向第一 UE发送 RRC连接重配置。
5609, 第一 UE向基站发送 RRC连接重配置完成。
5610, 基站释放第二 UE的资源。
可选的, 基站可以在确定一个可释放资源的第二 UE后的任何阶段释放 该第二 UE的资源。
S608-S610的具体实施方法与图 3的 S307〜S309的实施方法一致,不再 赘述。
