US 2016/0262197 A1 · ROUTING METHOD BETWEEN BASE STATIONS, SERVING GATEWAY, AND BASE STATION

Abstract

Embodiments of the present invention provide a routing method between base stations, a serving gateway, and a base station, where the method includes: receiving, by a first serving gateway, a first user data packet of first UE sent by a first base station, and determining, according to the first user data packet, whether the first serving gateway serves both the first UE and second UE, where the second UE is a communication peer end of the first UE; and if the first serving gateway determines that the first serving gateway serves both the first UE and the second UE, triggering, by the first serving gateway, the first base station to acquire first routing information required for direct communication with a second base station, and triggering the second base station to acquire second routing information required for direct communication with the first base station.

Dependent claims

A routing method between base stations, the method comprising:

receiving, by a first serving gateway, a first user data packet of first user equipment (UE) sent by a first base station, and determining, according to the first user data packet, whether the first serving gateway serves both the first UE and a second UE, wherein the second UE is a communication peer end of the first UE;
and
if the first serving gateway determines that the first serving gateway serves both the first UE and the second UE, triggering, by the first serving gateway, the first base station to acquire first routing information required for direct communication with a second base station, and triggering, by the first serving gateway, the second base station to acquire second routing information required for direct communication with the first base station, the first routing information and the second routing information are used for the first base station and the second base station to establish a direct connection, wherein the second base station serves the second UE.

A serving gateway, wherein the serving gateway is a first serving gateway and comprises:

a receiver, configured to receive a first user data packet of first user equipment (UE) sent by a first base station;
a processor, configured to determine, according to the first user data packet, whether the first serving gateway serves both the first UE and a second UE, wherein the second UE is a communication peer end of the first UE;
and
a transmitter, configured to:
after the processor determines that the first serving gateway serves both the first UE and the second UE, trigger the first base station to acquire first routing information required for direct communication with a second base station, and trigger, the second base station to acquire second routing information required for direct communication with the first base station, the first routing information and the second routing information are used for the first base station and the second base station to establish a direct connection, wherein the second base station serves the second UE.

2 more elements

A base station, wherein the base station is a first base station and comprises:

a transmitter, configured to send a first user data packet of first user equipment (UE) to a first serving gateway, so that the first serving gateway determines, according to the first user data packet, whether the first serving gateway serves both the first UE and a second UE, wherein if the first serving gateway serves both the first UE and the second UE, the first serving gateway triggers the first base station to acquire first routing information required for direct communication with a second base station, and the first serving gateway triggers the second base station to acquire second routing information required for communication with the first base station, the first routing information and the second routing information are used for the first base station and the second base station to establish a direct connection, wherein the second UE is a communication peer end of the first UE, and the second base station serves the second UE;
and
a processor, configured to acquire the first routing information according to the triggering by the first serving gateway, and establish the direct connection with the second base station according to the first routing information.
