物理层接口

The A1, A2, A3, A5 and A7 interfaces are based on the use of:

T1 digital transmission system interfaces. Each 1.544 Mbps interface provides 2456 or 2464 Kbps channels, which can be used for traffic or signaling as operator requires.E1 digital transmission interfaces consisting of 30*64 Kbps user channels can also be used for traffic or signaling. As the operator requires, and as applicable to the network. As a BS/MSC agreed option, dedicated DSO signaling link(s) may be used instead of the T1/E1 interface.T3 digital transmission interfaces supporting transmission rates of 43.232 Mbps.OC3 digital transmission interfaces supporting transmission rates of 155.52 Mbps.

The A8 to A15 interfaces are based on the use of the Internet Protocol, which can operate across various physical layer media (generally, Ethernet Fast LAN or GbE).

CDMA2000 - 1x接口

接口描述A1A1接口承载MSC的呼叫控制（CC）和移动性管理（MM）功能与BS（BSC）的呼叫控制组件之间的信令信息。CC接口承载MSC / VLR和HLR之间的用户信令信息。EE接口承载MSC / VLR和GMSC之间的用户信令信息。A2A2接口在MSC的交换机部件和BS的选择/分配单元（SDU）功能之间携带64Kbps无限制数字信息（UDI，用于ISDN）的64/56 Kbps PCM信息。A3A3接口携带源BS SDU功能和目标BS的信道元件组件（BTS）之间的编码用户信息（语音/数据）和信令信息。 这是A3接口端点的逻辑描述。 A3接口由两部分组成：信令和用户流量。 信令信息通过来自用户业务信道的单独逻辑信道承载，并控制用于传输用户业务的信道的分配和使用。A5A5接口在MSC和BSC的SDU功能之间携带全双工字节流。A7A7接口承载源BS和目标BS之间的信令信息。A8A8接口在BS和PCF之间进行通信。A9A9接口承载BS和PCF之间的信令信息。A10A10接口承载PCF和PDSN之间的用户流量。A11A11接口承载PCF和PDSN之间的信令信息。P-HP-H接口在归属代理（HA）和外地代理（FA）之间传送移动IP /用户应用数据。P1P1接口携带与用于数据会话发起的终端认证有关的信令信息，用于归属AAA中的会话控制（SC）/移动性管理（MM）功能和访问的AAA（用于CDMA2000 1x的认证，运营和计费实体）和HA之间的信令信息。 和FA分别。PiPi接口将FA和HA连接到外部分组数据网络，例如Internet，Intranet和Extranet。

CDMA2000 - 1x-EV-DO接口

接口描述A8A8接口承载接入网（AN）和分组控制功能（PCF）之间的用户流量。A9A9接口承载AN和PCF之间的信令信息。A10A10接口承载PCF和PDSN之间的用户流量。A11A11接口承载PCF和PDSN之间的信令信息。A12A12接口携带与AN中的SC / MM功能和AN AAA（阶段I）之间或者在PCF和AN AAA（1xEVDO的认证，授权和计费实体）之间的阶段II中的终端认证相关的信令信息。A13A13接口承载源AN中的SC / MM功能与目标AN中的SC / MM功能（阶段I）或源PCF中SC / MM功能与SC / MM功能之间的阶段II之间的信令信息 在目标PCF中。A14A14接口承载PCF中的SC / MM功能与AN之间的信令信息。A15当使用AN间寻呼时，A15接口在AN之间携带信令信息。AxAx接口承载PCF中的SC / MM功能和AN之间的用户流量。
