Retrieving One Or More Temporary Mobile Group Identities During A Connection Resume Procedure
A base station configure to receive, from a second base station, a retrieve user equipment context request message that includes a resume identity. The base station may further transmit a response message that includes one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that the wireless device is receiving or interested to receive. In an embodiment, the response message may be based on the resume identity.
1 . A method comprising:
receiving, by a first base station from a second base station, a retrieve user equipment context request message comprising a resume identity; and
transmitting, by the first base station, a response message comprising one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that a wireless device is receiving or interested to receive, wherein the response message, comprising the one or more TMGIs, is based on the resume identity.
2 . The method of claim 1 , wherein the response message further comprises:
a first identifier of a first packet flow of one or more packets flows;
at least one first vehicle-to-everything (V2X) parameter of the first packet flow indicating whether the first packet flow is for at least one first V2X service; and
a quality of service (QoS) indicator of the first packet flow.
3 . The method of claim 1 , wherein the response message further comprises at least one of:
an MBMS frequency;
an MBMS session identifier;
a group-radio network temporary identifier (G-RNTI) of an MBMS service or a V2X service;
a destination layer-2 identifier for an MBMS service or a V2X service;
an MBMS service priority; or
a V2X service priority.
4 . The method of claim 1 , further comprising receiving, by the first base station from the second base station, at least one configuration message of a system information block type 20 (SIB20) or a single cell point to multipoint (SCPTM) configuration message.
5 . The method of claim 4 , wherein the at least one configuration message comprising one or more parameters for the at least one of the one or more MBMS services.
6 . The method of claim 1 , further comprising updating, by the first base station, one or more traffic parameters of at least one of the one or more MBMS services.
7 . The method of claim 1 , further comprising increasing, by the first base station, a priority of at least one of the one or more MBMS services.
8 . The method of claim 1 , wherein the one or more TMGIs is retrieved based at least on the resume identity.
9 . The method of claim 1 , wherein the transmitting the response message is further based on the retrieve user equipment context request message.
10 . A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
receive, from a second base station, a retrieve user equipment context request message comprising a resume identity; and
transmit a response message comprising one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that a wireless device is receiving or interested to receive, wherein the response message, comprising the one or more TMGIs, is based on the resume identity.
11 . The base station of claim 10 , wherein the response message further comprises:
a first identifier of a first packet flow of one or more packets flows;
at least one first vehicle-to-everything (V2X) parameter of the first packet flow indicating whether the first packet flow is for at least one first V2X service; and
a quality of service (QoS) indicator of the first packet flow.
12 . The base station of claim 10 , wherein the response message further comprises at least one of:
an MBMS frequency;
an MBMS session identifier;
a group-radio network temporary identifier (G-RNTI) of an MBMS service or a V2X service;
a destination layer-2 identifier for an MBMS service or a V2X service;
an MBMS service priority; or
a V2X service priority.
13 . The base station of claim 10 , wherein the instructions, when executed, further cause the base station to receive at least one configuration message of a system information block type 20 (SIB20) or a single cell point to multipoint (SCPTM) configuration message.
14 . The base station of claim 13 , wherein the at least one configuration message comprising one or more parameters for the at least one of the one or more MBMS services.
15 . The base station of claim 10 , wherein the instructions, when executed, further cause the base station to update one or more traffic parameters of at least one of the one or more MBMS services.
16 . The base station of claim 10 , wherein the instructions, when executed, further cause the base station to increase a priority of at least one of the one or more MBMS services.
17 . The base station of claim 10 , wherein the transmission of the response message is further based on the retrieve user equipment context request message.
18 . A system comprising:
a first base station; and
a second base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
receive, from the first base station, a retrieve user equipment context request message comprising a resume identity; and
transmit, to the first base station, a response message comprising one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that a wireless device is receiving or interested to receive, wherein the response message, comprising the one or more TMGIs, is based on the resume identity.
